 (As Representatives of the Several
Underwriters named in Schedule I hereto)


Gentlemen:

          ImageMatrix Corporation, a Colorado corporation (the "Company"),
proposes to sell to the several underwriters named in Schedule I hereto (the
"Underwriters"), on whose behalf Neidiger, Tucker, Bruner, Inc. and Joseph
Charles & Assoc., Inc. are acting as the representatives (the
"Representatives"), 1,400,000 Units (the "Firm Units"), each Unit consisting of
one share of the Common Stock, no par value, of the Company (the "Common Stock")
and one Redeemable Common Stock Purchase Warrant (the "Warrants").  The terms of
the Units and the components of the Units shall be as described in the
Registration Statement which is described below in Section 1(a).  In addition,
for the sole purpose of covering over-allotments in connection with the sale of
the Firm Units, the Company proposes to grant to the several Underwriters an
option to purchase up to an additional 210,000 Units (the "Option Units").

          The Company further agrees to sell and issue to you individually, and
not in your capacities as Representatives, five-year warrants (the
"Representatives' Warrants") to purchase, for 120% of the public offering price
of the Firm Units, an aggregate of 140,000 Units (the "Representatives' Warrant
Units").   Each Representatives' Warrant Unit consists of one share of Common
Stock ("Warrant Unit Shares") and one Redeemable Common Stock Purchase Warrant
("Underlying Warrant").  The terms and conditions of the Representatives'
Warrants, Representatives' Warrant

                                      -1-

 
Units, Warrant Unit Shares and Underlying Warrant, including the purchase price
thereof, shall be as set forth in the Representatives' Warrant Agreement filed
as an exhibit to the Registration Statement.

          Each of the Representatives has advised the Company that:  (a) it is
authorized to enter into this Agreement on behalf of the several Underwriters;
and (b) the several Underwriters are willing, acting severally and not jointly,
to purchase the numbers of Firm Units set forth opposite their respective names
in Schedule I.

          The Firm Units, any Option Units purchased pursuant to this Agreement
and the Representatives' Warrant Units are collectively called herein the
"Units" and the Warrants included in the Units and the Representatives' Warrants
are collectively called herein the "Warrants."  The shares of Common Stock
issuable upon exercise of the Warrants are collectively called the "Warrant
Shares" and the Warrant Shares, together with the shares of Common Stock
included in the Units, are collectively called the "Shares."  The Shares,
Warrants and the Representatives' Warrant Units are sometimes referred to herein
collectively as the "Underlying Securities."  The term "Underwriters" refers to
any individual member of the underwriting syndicate and includes any party
substituted for an Underwriter under Section 7 hereof.

          In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:

         1.  Representations and Warranties.  The Company represents and
warrants to, and agrees with, each Underwriter that:

             (a) A registration statement on Form SB-2 (File No. 33-31990), and
         as a part thereof a preliminary prospectus and related exhibits, for
         registration of the Units, Warrants, and Shares has been prepared by
         the Company in conformity with the requirements of the Securities Act
         of 1933, as amended, and the rules and regulations promulgated
         thereunder (the "1933 Act" and the "1933 Act Regulations",
         respectively) has been filed with the Securities and Exchange
         Commission (the "Commission"). One or more amendments to such
         registration statement have been so prepared and filed in the form
         delivered to you. No other amendment thereto has been filed and none
         will be filed with the Commission prior to the time such registration
         statement becomes effective which shall be disapproved by you promptly
         after reasonable notice thereof. The registration statement, including
         the prospectus, Part II, the documents incorporated by reference
         therein and all schedules and exhibits thereto, as amended at the time
         when it becomes effective is hereinafter referred to as the
         "Registration Statement." Any prospectus included in the Registration
         Statement and in any amendments thereto prior to the effective date of
         the Registration Statement is referred to herein as the "Preliminary
         Prospectus." The prospectus on file with the Commission when the
         Registration Statement becomes effective is herein referred to as the
         "Prospectus," except that if the prospectus filed by the Company
         pursuant to Rules 424(b) and 430A of the 1933 Act Regulations of the
         Commission differs from the prospectus on file at the time the

                                      -2-

 
         Registration Statement becomes effective, the term "Prospectus" shall
         also include the Rules 424(b) and 430A prospectus from and after the
         time it is transmitted to the Commission for filing.

             (b) No order preventing or suspending the use of any Preliminary
         Prospectus has been issued by the Commission or any state of the United
         States or other regulatory body, and each Preliminary Prospectus, at
         the time of filing thereof, did not contain an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading; provided,
         however, that the foregoing shall not apply to statements or omissions
         made in reliance upon and in conformity with written information
         furnished to the Company by you or by an Underwriter(s) through you
         expressly for use in the Registration Statement or Prospectus.

             (c) When the Registration Statement becomes effective, and at all
         times subsequent thereto up to and including each Closing Date (as
         defined in Section 3), the Registration Statement, any post-effective
         amendment thereto and the Prospectus, each as amended or supplemented,
         will contain all statements which are required to be stated therein in
         accordance with the 1933 Act and 1933 Act Regulations and shall
         otherwise comply in all material respects with the requirements of the
         1933 Act and 1933 Act Regulations. No such document shall contain any
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading; provided, however, that the foregoing shall not apply to
         statements or omissions made in reliance upon and in conformity with
         written information furnished to the Company by an Underwriter(s)
         through you expressly for use in the Registration Statement or
         Prospectus.

             (d) To the best of the Company's knowledge and information, each
         firm of accountants which certified any of the financial statements
         included in the Registration Statement is an independent certified
         public accountant as required by the 1933 Act and the 1933 Act
         Regulations. The financial statements (including the related notes)
         included in the Registration Statement, any Preliminary Prospectus and
         the Prospectus present fairly the financial condition, the results of
         operations, changes in financial condition and cash flows of the
         Company at the dates and for the periods indicated and have been
         prepared in accordance with generally accepted accounting principles
         and accounting requirements of the 1933 Act and the 1933 Act
         Regulations applied on a consistent basis throughout the periods
         indicated. All adjustments necessary for a fair presentation of results
         for such periods have been made. The selected financial data included
         in the Registration Statement, any Preliminary Prospectus and the
         Prospectus present fairly the information shown therein and have been
         compiled on a basis consistent with the audited financial statements
         included in the Registration Statement, any Preliminary Prospectus and
         the Prospectus.

                                      -3-

 
             (e) The Company is a corporation duly organized, validly existing
         and in good standing under the laws of the State of Colorado, with full
         power and authority (corporate and other) to own or lease its
         properties and conduct its business as described in the Prospectus, and
         is duly qualified to do business and is in good standing in each
         jurisdiction in which the character of the business conducted by it or
         the location of the properties owned or leased by it makes such
         qualification necessary, except where the failure to do so would not
         have a material adverse effect. The Company holds all material
         licenses, certificates, permits, consents, orders and approvals or
         other authorizations necessary to lease or own, as the case may be, and
         to operate its property and conduct its business as described in the
         Prospectus. None of the activities or businesses of the Company is in
         violation of any law, rule, regulation or order of the United States,
         any state, county or locality, or of any agency or body of the United
         States or of any state, county or locality, other than violations which
         would not have a material adverse effect upon the Company. The Company
         has no "subsidiaries" (as that term is defined in the 1933 Act
         Regulations) and has not had any subsidiaries since its formation,
         other than the subsidiary or subsidiaries ("Subsidiary" or
         "Subsidiaries") identified in the Registration Statement. (As used
         herein, the term "Company," when used with respect to any period during
         which any Subsidiary was a subsidiary of the Company, shall be deemed
         to include such Subsidiary or Subsidiaries.) The Company does not own
         or hold any interest in any corporation, partnership, joint venture or
         other entity except as described in the Registration Statement and
         Preliminary Prospectus and the Prospectus.

             (f) The capitalization of the Company is or will be as set forth
         under the caption "Capitalization" in the Prospectus, and the Units and
         the Underlying Securities conform or will conform to the description
         thereof contained under the caption "Description of Securities" in the
         Prospectus. The outstanding shares of Common Stock have been, and the
         Units and their components upon issuance and delivery and payment
         therefor in the manner contemplated by this Agreement, will be, duly
         authorized, validly issued, fully paid and nonassessable. The shares of
         Common Stock are not subject to preemptive rights or other rights to
         subscribe for or to purchase additional securities from the Company, or
         subject to any restriction upon voting or transfer, pursuant to the
         Company's Articles of Incorporation or Bylaws, as amended, or any
         agreement (except as provided in Section 4(u) hereof) or other
         instrument to which the Company is a party or by which it is bound.
         Neither the filing of the Registration Statement nor the offering or
         sale of the Units, Warrants or Shares, as contemplated by this
         Agreement and the Representatives' Warrant Agreement, gives rise to any
         rights other than those which have been waived or satisfied.

             (g) Except as may be described in or contemplated by the
         Prospectus, there has not been any material adverse change in, or any
         adverse development that materially affects, the business, properties,
         financial condition, results of operations or prospects of the Company
         from the date as of which information is given in the Prospectus; and
         except as described in the Prospectus, the Company has not, directly or
         indirectly, incurred any

                                      -4-

 
         material liabilities or obligations, direct or contingent, not in the
         ordinary course of business, other than obligations related to the
         offering of the Units and as otherwise provided herein, or entered into
         any transaction not in the ordinary course of business which is
         material to the business of the Company and required to be disclosed in
         the Prospectus. Except as described in or contemplated by the
         Prospectus, there has not been any material change in the capital stock
         of, or any incurrence of long-term debt by, the Company, or any
         issuance or grant of options, warrants or rights to purchase the
         capital stock of the Company, or any declaration or payment of any
         dividend on the capital stock of the Company from the date as of which
         information will be given in the Prospectus.

             (h) The Company is not, nor with the giving of notice or lapse of
         time or both will it be, in violation of or in default under, nor will
         the execution or delivery hereof or of the Representatives' Warrant
         Agreement or consummation of the transactions contemplated hereby or
         thereby result in a violation of, or constitute a default that would be
         material to the business of the Company under the Company's Articles of
         Incorporation or Bylaws, as amended, or other governing documents of
         the Company, or any material agreement, deed of trust, indenture or
         other instrument, to which the Company is a party or by which it is
         bound, or to which any of its properties is subject, nor will the
         Company's performance of its obligations hereunder or under the
         Representatives' Warrant Agreement violate any law, rule,
         administrative regulation or decree of any court or any governmental
         agency or body having jurisdiction over the Company or any of its
         properties, or result in the creation or imposition of any lien,
         charge, claim or encumbrance upon any property or asset of the Company.
         Except for an order of the Commission declaring the Registration
         Statement effective, and except for permits and similar authorizations
         required under the securities or "blue sky" laws of certain states of
         the United States and for such permits and authorizations which have
         been obtained, no consent, approval, authorization or order of any
         court, governmental agency or body or financial institution is required
         in connection with the consummation of the transactions contemplated by
         this Agreement or the Representatives' Warrant Agreement.

             (i) This Agreement, including the Representatives' Warrant
         Agreement and the other agreements of the Company provided for herein,
         has been duly authorized, executed and delivered by the Company and
         constitute the valid and binding agreement of the Company enforceable
         against the Company in accordance with its terms, except insofar as
         rights to indemnity and/or contribution may be limited by federal or
         state securities laws or the public policy underlying such laws and
         except as enforcement may be limited by bankruptcy, insolvency,
         reorganization or other similar laws affecting creditors' rights
         generally, and be subject to general principles of equity (regardless
         of whether such enforceability is considered in a proceeding in equity
         or at law). The Units, Warrants and Shares have been duly authorized
         for issuance and sale, and, when issued pursuant to this Agreement and
         the Representatives' Warrant Agreement against payment of the
         consideration therefor, will be validly issued, fully paid and
         nonassessable and not subject to preemptive rights. The Shares issuable
         upon exercise of the Warrants have been duly

                                      -5-

 
         authorized and reserved for issuance upon exercise of the Warrants and
         when issued upon payment of the consideration therefor will be validly
         issued, fully paid and nonassessable shares of Common Stock and not
         subject to preemptive rights.

             (j) The Company has good and marketable title to each of the items
         of real property and good title to each of the items of personal
         property which are described or referred to in the Prospectus as being
         owned by it and valid and enforceable leasehold interests in each of
         the items of real and personal property which are referred to in the
         Prospectus as being leased by it, in each case free and clear of all
         liens, encumbrances, claims, security interests and defects, other than
         those described in the Prospectus and those which do not and will not
         have a material adverse effect upon the value and the Company's use of
         such properties or the Company's business, financial condition or
         results of operations.

             (k) There is no litigation or governmental proceeding to which the
         Company is a party or to which any property of the Company is subject
         or which is pending in which the Company has been served or, to the
         best knowledge of the Company, is otherwise pending or threatened
         against the Company, nor is there any basis therefor, which will result
         in any material adverse change in the financial condition, results of
         operations, business or prospects of the Company or which is required
         to be disclosed in the Prospectus which has not been disclosed in the
         Prospectus. To the Company's knowledge, no labor disturbance by the
         employees of the Company exists or is imminent which, if it now exists
         or comes to exist, is expected materially to affect adversely the
         financial condition, results of operations, business or prospects of
         the Company or which is required to be disclosed in the Prospectus.

             (l) The descriptions in the Registration Statement and the
         Prospectus of material contracts and other documents are accurate in
         all material respects and present fairly the information required to be
         disclosed, and there are no contracts or other documents required to be
         described in the Registration Statement or Prospectus or to be filed as
         exhibits to the Registration Statement under the 1933 Act or the 1933
         Act Regulations which have not been so described or filed as required.
         Each material contract or other instrument (however characterized or
         described) to which the Company is a party or by which its property or
         business is or may be bound or affected and to which reference is made
         in the Prospectus has been duly and validly executed by the Company, is
         in full force and effect in all material respects and is enforceable
         against the parties thereto in accordance with its terms, subject, as
         to enforcement of remedies, to applicable bankruptcy, insolvency,
         reorganization, moratorium and other laws affecting the rights of
         creditors generally and the discretion of courts in granting equitable
         remedies; and none of such contracts or instruments has been assigned
         by the Company and neither the Company nor, to the best knowledge of
         the Company, any other party is in material default thereunder, which
         default would have a material adverse effect on the business,
         prospects, financial condition or results of operations of the Company;
         and, to the best knowledge of the Company, no event has occurred which,
         with the lapse of time or the giving of notice, or both, would
         constitute a default thereunder,

                                      -6-

 
         which would have a material adverse effect on the business, prospects,
         financial condition or results of operations of the Company. None of
         the material provisions of such contracts or instruments violates any
         existing applicable law, rule, regulation, judgment, order or decree of
         any governmental agency or court having jurisdiction over the Company
         or any of its assets or business including, without limitation, those
         relating to health care or employee benefits, which violation would
         have a material adverse effect on the business, prospects, financial
         condition or results of the operations of the Company.

             (m) The Company has filed with the appropriate federal, state and
         local governmental agencies, and all foreign countries and political
         subdivisions thereof, all tax returns, including franchise tax returns,
         which are required to be filed or has duly obtained extensions of time
         for the filing thereof and has paid all taxes shown on such returns and
         all assessments received by it to the extent that the same have become
         due. The provisions for income taxes payable, if any, shown on the
         financial statements filed with or as part of the Registration
         Statement are sufficient for all accrued and unpaid foreign and
         domestic taxes, whether or not disputed, and for all periods to and
         including the dates of such financial statements. The Company has not
         executed or filed with any taxing authority, foreign or domestic, any
         agreement extending the period for assessment or collection of any
         income taxes and is not a party to any pending action or proceeding by
         any foreign or domestic governmental agency for assessment or
         collection or taxes; and no claims for assessment or collection of
         taxes have been asserted against the Company.

             (n) The Company is not in violation of or in default under (i) any
         term or provision of its Articles of Incorporation or Bylaws, as
         amended; (ii) any material term or provision or any material financial
         covenant of any indenture, mortgage, contract, commitment or other
         agreement or instrument to which it is a party or by which it or any of
         its property or business is or may be bound or affected; or (iii) any
         existing applicable law, rule, regulation, judgment, order or decree of
         any governmental agency or court, domestic or foreign, having
         jurisdiction over the Company or any of its properties or business the
         violation of which would have a material adverse effect on the Company.
         The Company owns, possesses or has obtained all governmental and other
         (including those obtainable from third parties) licenses, permits,
         certifications, registrations, approvals or consents and other
         authorizations necessary to own or lease, as the case may be, and to
         operate its properties, whether tangible or intangible, and to conduct
         any of the business operations of the Company as presently conducted
         (except where the Company's failure to obtain such license, permit,
         certification, registration, approval, consent or other authorization
         would not materially adversely affect the Company) and all such
         licenses, permits, certifications, registrations, approvals, consents
         and other authorizations are outstanding and in good standing, and
         there are not any proceedings pending or, to the best of the knowledge
         of the Company, threatened, seeking to cancel, terminate or limit such
         licenses, permits, certifications, registrations, approvals or consents
         or other authorizations.

                                      -7-

 
             (o) The books, records and accounts of the Company accurately and
         fairly reflect, in reasonable detail, the transactions in and
         dispositions of assets of, and results of operations of, the Company.
         The Company maintains a system of internal accounting controls
         sufficient to provide reasonable assurances that (i) transactions are
         executed in accordance with management's general or specific
         authorization; (ii) transactions are recorded in a manner sufficient to
         permit preparation of financial statements in conformity with
         applicable generally accepted accounting principles and to maintain
         accountability for assets; (iii) access to assets is permitted only in
         accordance with management's general or specific authorizations; and
         (iv) the recorded accountability for assets is compared with existing
         assets at reasonable intervals and appropriate action is taken with
         respect to any differences. The Company's internal accounting controls
         and procedures are sufficient to cause the Company to comply in all
         material respects with applicable law.

             (p) Neither the Company nor to the Company's knowledge any officer,
         director or employee of or agent acting on behalf of the Company has at
         any time (i) made any contributions to any candidate for political
         office in violation of law, or failed to disclose fully any
         contributions to any candidate for political office in accordance with
         any applicable statute, rule, regulation or ordinance requiring such
         disclosure, (ii) made any payment to any governmental officer or
         official, or other person charged with similar public or quasi-public
         duties, other than payments required or allowed by applicable law,
         (iii) made any payment outside the ordinary course of business to any
         purchasing, selling, licensing or reselling agent or person charged
         with similar duties of any entity to which the Company sells or from
         which the Company buys products, services or rights for the purpose of
         influencing such agent or person to buy products, services or rights
         from or sell products, services or rights to the Company, or (iv)
         engaged in any transaction on behalf of the Company, maintained any

         been and are reflected in the normally maintained books and records of
         the Company.

             (q) The Company's properties are adequately insured by insurors of
         recognized financial responsibility against loss or damage by fire and
         other appropriate risks (including computer failure), the Company's
         performance is adequately guaranteed by bonding firms of recognized
         financial responsibility in accordance with all requirements under its
         agreements and all applicable regulations and rules applicable to its

         performance guaranty bonds as are prudent or customarily maintained by
         companies of comparable size and in the same or similar business and in
         the same or similar localities; the Company has not been refused any
         insurance or bonding coverage sought or applied for; and the Company
         has no reason to believe that it will not be able to renew its existing
         insurance coverage and performance guaranty bonds as and when such
         coverage expires or to obtain similar coverage from similar insurors
         and bonding firms as may be necessary to continue its business at a
         cost that would not

                                      -8-

 
         materially and adversely affect the condition (financial or otherwise),

         except as described in or contemplated by the Prospectus.

             (r) The Company owns or possesses adequate and enforceable rights

         Intangibles described or referred to in the Prospectus and any
         Intangibles incorporated into any product of the Company described in
         the Prospectus. The Company is not in material breach of, or in
         material default under, any license, reseller, integrator or other
         agreement or instrument to which any Intangibles are subject. All third
         parties whose consent to assignment of any agreement with respect to
         the Intangibles or any product of the Company or any third party which
         incorporates any Intangibles have consented to such assignment to the
         Company. Except as may be set forth in the Prospectus, the Company has
         not received any notice of infringement of or conflict with, and to
         best of the Company's knowledge, the Company is not infringing or in
         conflict with, asserted rights of others with respect to any Intangible
         which, singly or in the aggregate, if the subject of a decision, ruling
         or finding unfavorable to the Company, would materially and adversely

         members of the families of any of them, which are required by the 1933
         Act Regulations to be described in the Registration Statement, which
         are not fully and adequately described therein.

             (t) The Company is not, and, upon completion of the offering of the

         Company Act of 1940, as amended.

             (u) The Company has not taken and shall not take, directly or

         Act"), or designed to cause or result in, or which has constituted or
         which might reasonably be expected to constitute, the stabilization or
         manipulation of the price of the Units or the Underlying Securities to
         facilitate the sale or resale of any of such securities.

                                      -9-

         Regulations", respectively) and the Units, the Common Stock and the
         Warrants have been approved for quotation on the National Association
         of Securities Dealers Automated Quotation System ("NASDAQ") upon

             (w) No person (other than a person affiliated with either of you)
         has rendered services of any nature whatsoever to the Company for which
         such person has received compensation required to be aggregated with
         the compensation to be received by the Underwriters in connection with
         this offering and no person has any claim for services in the nature of
         a finder's fee or brokerage fee with respect to this offering for which
         the Company or any Underwriter may be responsible.

             (x) The Company has retained a public relations firm acceptable to
         the Company and you for a period of six months commencing with the Firm

         purpose of covering any over-allotments in connection with the

         purchase, severally and not jointly, up to an aggregate of 210,000
         Option Units in the aggregate. The purchase price per Unit to be paid
         for the Option Units shall be the same price per Unit as for the Firm

         of the Option Units at any time or times not more than 60 days
         subsequent to the effective date of this Agreement. No Option Units
         shall be sold and delivered unless the Firm Units previously have been,

          Delivery of certificates for the Firm Units and the Option Units shall

one full Business Day prior to such Closing Date.  Time shall be of the essence,
and delivery at the time and place specified in this Agreement is a further
condition to the obligations of each Underwriter.

         4.  Covenants.   The Company covenants and agrees with each
Underwriter as follows:

             (a) The Company shall comply with the provisions of and make all
         requisite filings with the Commission pursuant to Rule 430A and Rule
         424(b) under the 1933 Act and 1933 Act Regulations and notify you
         promptly, and confirm in writing, of all such filings. The Company
         shall use its best efforts to cause the Registration Statement and any
         amendment thereto to become effective and, upon notification from the
         Commission that the Registration Statement or any amendment thereto has
         become effective, shall so advise you promptly, in writing. The Company
         shall notify you promptly of any request by the Commission for any
         amendment of or supplement to the Registration Statement or the
         Prospectus or for additional information; the Company shall carefully
         prepare and file with the Commission promptly upon your request, any
         amendment of or supplement to the Registration Statement or Prospectus
         which, in your reasonable opinion, may be necessary or advisable in
         connection with the distribution of the Units; and the Company shall
         not file any amendment of or supplement to the Registration Statement
         or the Prospectus which is not approved by you after reasonable notice
         from the Company to you, which approval shall not be unreasonably
         withheld or delayed. The Company shall advise you promptly of the
         issuance by the Commission, any state securities commission or any
         other regulatory body of any stop order or other order suspending the
         effectiveness of the Registration Statement, suspending or preventing
         the use of the Prospectus or suspending the qualification of the Units
         and the securities comprising the Units for offering or sale in any
         jurisdiction, or of the institution of any proceedings for any such
         purpose; and the Company shall use its best efforts to prevent the
         issuance of any stop order or other such order and, should a stop order
         or other such order be issued, to obtain as soon as possible the
         lifting thereof.

             (b) The Company shall furnish to the Representatives and their
         counsel, from time to time and without charge, a reasonable number of
         copies of the Registration Statement as originally filed and as
         subsequently amended, of which at least four copies of each such filing
         shall be manually signed and shall include all exhibits.

             (c) Within the time during which a Prospectus relating to the Units
         is required to be delivered under the 1933 Act and 1933 Act
         Regulations, the Company shall comply

                                      -12-

 
         with all requirements imposed upon it by the 1933 Act or the 1934 Act,
         as now or hereafter amended, and by the 1933 Act Regulations, as from
         time to time in force, so far as is necessary to permit the continuance
         of sales of or dealings in the Units as contemplated by the provisions
         hereof and the Prospectus. If during such period any event occurs as a
         result of which the Prospectus as then amended or supplemented would
         include an untrue statement of a material fact or omit to state a
         material fact necessary to make the statements therein, in the light of
         the circumstances then existing, not misleading, or if during such
         period it is otherwise necessary, in the opinion of the Company or in
         your opinion, to amend the Registration Statement or supplement the
         Prospectus to comply with the 1933 Act, the Company or you, as the case
         may be, shall promptly notify the other party and the Company shall
         amend the Registration Statement or supplement the Prospectus (at the
         expense of the Company) so as to correct such statement or omission or
         effect such compliance.

             (d) The Company shall cooperate with you and your counsel in
         connection with the registration or qualification of the Units for sale
         under the "blue sky" laws of such jurisdictions which you shall
         designate and to continue such qualifications in effect for as long a
         period as you may reasonably request, except that in no event shall the
         Company be obligated in connection therewith to qualify as a foreign
         corporation or as a dealer in any jurisdiction where it is not already
         so qualified, or to execute a general consent for service of process in
         suits other than those arising out of the offer and sale of the Units,
         or to take any action which would subject it to taxation in any
         jurisdiction where it is not now so subject.

             (e) The Company shall make generally available to its security
         holders (and shall deliver to you), in the manner contemplated by Rule
         158(b) under the 1933 Act, as soon as practicable but in any event not
         later than 45 days after the end of its fiscal quarter in which the
         first anniversary date of the effective date of the Registration
         Statement occurs, an earnings statement satisfying the requirements of
         Section 11(a) of the 1933 Act covering a period of at least twelve
         consecutive months beginning after the effective date of the
         Registration Statement.

             (f) For a period of five (5) years from the effective date of the
         Registration Statement, the Company will deliver to you on a timely
         basis (i) a copy of each report, including, without limitation, reports
         on Form 8-K, 10-C, 10-K (or 10-KSB) and 10-Q (or 10-QSB) or any
         successor form and exhibits thereto filed with or furnished by the
         Company to the Commission, any securities exchange or the National
         Association of Securities Dealers, Inc. (the "NASD") on the date each
         such report or document is so filed or furnished; (ii) as soon as
         practicable, copies of any reports or communications (financial or
         other) of the Company mailed to its security holders; (iii) as soon as
         practicable, a copy of any Schedule 13D, 13G, 14D-1, 13E-3 or 13E-4 (or
         any successor form) received or prepared by the Company from time to
         time; and (iv) such additional information concerning the business and
         financial condition of the Company as you may from time to time
         reasonably request and which can be prepared or obtained by the Company
         without unreasonable effort or expense.

                                      -13-

 
             (g) The Company shall apply the net proceeds of the sale of the
         Firm Units and any Option Units as set forth in the Prospectus under
         the caption "Use of Proceeds." In particular, the Company shall prior
         to May 30, 1996 pay in full the Company's obligations to ENTEX and the
         Company shall prior to May 30, 1996 pay in full the outstanding
         principal amount and all interest and principal payable in respect of
         the Company's obligations to BankOne, regardless of the extension of
         due date on the BankOne obligation executed between the Company and
         BankOne in February 1996 on any forbearance of any default in respect
         of the death of any Co-Borrower. Prior to the full application of such
         net proceeds in the manner therein contemplated, the Company shall
         invest or reinvest such proceeds only in high quality, short-term
         investments or cash equivalents as described in the Prospectus.

             (h) The Company shall file such reports with the Commission with
         respect to the sale of the Units and the application of the proceeds
         therefrom as may be required in accordance with Rule 463 under the 1933
         Act.

             (i) The Company shall pay or cause to be paid (i) all expenses
         (including stock transfer taxes, if any) incurred in connection with
         the delivery of the Firm Units and Option Units to the Underwriters,
         (ii) all fees and expenses (including, without limitation, fees and
         expenses of the Company's accountants and counsel) in connection with

         Registration Statement (including the financial statements therein and
         all amendments and exhibits thereto), each Preliminary Prospectus and
         the Prospectus as amended or supplemented, and the copying, delivery
         and shipping (but not preparation) of the Underwriting Agreement and
         other underwriting documents, including Underwriters' Questionnaires,
         Underwriters' Powers of Attorney, Blue Sky Memoranda, Agreements Among
         Underwriters and Selected Dealer Agreements and any letters
         transmitting the offering materials to selling group members (including
         costs of mailing and shipment); (iii) all filing fees and fees for
         legal services and disbursements of Representatives' counsel incurred
         in connection with the registration/qualification of the Units under
         state securities laws; (iv) the filing fees, listing fees and costs of
         the NASD and NASDAQ; (v) applicable listing or similar fees; (vi) the
         cost of printing certificates representing the components comprising
         the Units; (vii) the cost and charges of the transfer agent or
         registrar for the Units and Underlying Securities; (viii) the costs of
         "tombstone" advertisements in such publications as you shall reasonably
         request, as well as the costs of any other advertising undertaking at
         the Company's request, including all graphic slide costs (not to exceed
         $3,000 in the aggregate); (ix) the costs of preparing, printing and
         distributing bound volumes for you and your counsel; (x) the costs of
         all due diligence meetings to be held in cities selected by mutual
         agreement of the Company and you; provided, however, each of the
         Company and you shall be solely responsible for the travel expenses of
         their respective employees or representatives to attend such meetings;
         and (xi) all other costs and expenses incident to the performance of
         the obligations of the Company under this Agreement which are not
         otherwise provided for in this section. In addition, the Company shall
         also pay to you, individually and not in your capacity as
         Representatives, at the

                                      -14-

 
         applicable Closing Date, a nonaccountable expense allowance equal to 3%
         of the initial public offering price of the Units purchased on such
         Closing Date (including Option Units purchased pursuant to the option
         granted pursuant to Section 2 hereof). If the sale of the Units
         provided for herein is not consummated by reason of any termination of
         this Agreement pursuant to Section 8(b) hereof, or by reason of any
         failure, refusal or inability on the part of the Company to perform any
         agreement on its part to be performed or because any condition of the
         Underwriter's obligations set forth in Section 5 herein is not
         fulfilled, the Company shall reimburse the Representatives for all of
         the Representatives' accountable out-of-pocket expenses (including
         reasonable fees and disbursements of Representatives' counsel) actually
         incurred in connection with the investigation, preparing to market and
         marketing of the Units or in contemplation of performing
         Representatives' obligations hereunder, such reimbursement not to

         1933 and 1934 Act Regulations and reported on by its independent
         certified accountants. For five (5) years after the First Closing Date,
         at its expense, the Company shall furnish to you (i) as soon as
         practicable after the end of each fiscal year, a balance sheet of the
         Company and any Subsidiary as at the end of such fiscal year together
         with statements of income or operations, shareholders' equity and cash

         unreasonable effort or expense.

             (k) If and so long as the Company has an active subsidiary or
         subsidiaries, the financial statements provided for in Section 4(j)
         will be on a consolidated basis to the extent the accounts of the
         Company and its subsidiary or subsidiaries are consolidated in reports
         furnished to its shareholders generally. Separate financial statements
         shall be furnished for all subsidiaries whose accounts are not
         consolidated but which at the time are significant subsidiaries as
         defined in the 1933 and 1934 Act Regulations.

         accounting controls described in Section 1(o).

             (n) The Company shall use its best efforts to maintain the
         inclusion of the Units, the Common Stock and the Warrants for quotation
         on NASDAQ. If the Common Stock qualifies at a future time for quotation
         on the National Market System of NASDAQ ("NASDAQ NMS"), the Company
         will use its best efforts to obtain inclusion of the Common Stock and
         Warrants for quotation of NASDAQ NMS.

             (o) For a period of five (5) years from the effective date of the
         Registration Statement, the Company shall (i) use its best efforts to

         beneficial owners of securities held by Depository Trust Company and
         any other nominees; and (iii) retain such accounting firm as its
         independent public accountants as shall be reasonably acceptable to
         you.

             (p) The Company shall take such steps as shall be necessary to
         ensure that neither the Company nor any subsidiary thereof shall become
         an "investment company" within the meaning of such term under the
         Investment Company Act of 1940, as amended, and the rules and
         regulations thereunder.

             (q) Prior to the filing and closing of the public offering
         contemplated by this Agreement, no discussions will be held by any
         representative of the Company with any member of the news media or
         release any information or other publicity about the Company, its
         business or its management without the approval of counsel to the
         Company and Representatives.

             (s) The Company shall use its best efforts to obtain and to cause
         to be in force within 60 days of the effective date of the Registration
         Statement policies of life insurance in the face amounts and on the
         lives of such key employees of the Company as designated by the
         Representatives; and each policy shall identify the Company as the
         beneficiary thereof.

                                      -16-

 
             (t) For a period of 12 months from the effective date of the
         Registration Statement, the Company shall not authorize or otherwise
         effect any change in the compensation to any officer and/or director of
         the Company without 30 days' prior written notice to you.

             (u) Prior to the effective date of the Registration Statement, the
         Company shall cause (i) each officer, director of the Company and each
         holder of 5% or more of the Company's Common Stock (or securities
         convertible into Common Stock) to furnish to you their written
         agreement, in form and content satisfactory to your counsel, whereby
         each such person shall not sell, pledge, assign or otherwise dispose or
         contract to dispose of any of their shares of Common Stock (or
         securities convertible into Common Stock) for a period of 12 months
         following the effective date of the Registration Statement without the
         prior written consent of Neidiger, Tucker, Bruner, Inc., and (ii) each
         other holder of the Company's Common Stock (or securities convertible
         into Common Stock) to furnish to you their written agreement, in form

         effective date of the Registration Statement without the prior written
         consent of Neidiger, Tucker, Bruner, Inc. The foregoing agreements
         shall also provide that any sale of shares of Common Stock by such
         persons during the applicable restrictive period, and which sale is
         subject to Rule 144 under the 1933 Act (or comparable provision under
         the 1933 Act) shall be made in transactions by or directly with
         Neidiger, Tucker, Bruner, Inc.

             (v) So long as any Warrants are outstanding, the Company shall use
         its best efforts to cause post-effective amendments to the Registration
         Statement to become effective in compliance with the 1933 Act and
         without any lapse of time between the effectiveness of any such post-
         effective amendments and cause a copy of each Prospectus, as then
         amended, to be delivered to each holder of record of a Warrant and to
         furnish to the Underwriters and each dealer as many copies of each such
         Prospectus as the Underwriters or dealer may reasonably request.

                                      -17-

 
             (w) On the Firm Closing Date, the Company and NTB shall enter into
         an agreement which shall provide that NTB shall have the right to
         designate one person as an advisor to the Company's Board of Directors.
         Such advisor will be reimbursed for his or her expenses in attending
         meetings of the Board of Directors and will receive cash compensation
         equal to that received by any other outside director but will have no
         power to vote as a director. Such person shall be indemnified by the
         Company against any claim arising out of his or her participation in
         meetings of the Board of Directors to the same extent as directors.
         During the stated 3 year period, NTB's advisor to the Company's Board

         Actual Meeting; (iii) furnished with a copy of all public filings by
         the Company and Company press releases as released; (iv) updated by the

         applicable law. During the subject 3 year period, the Company will hold
         meetings of its Board of Directors at intervals of not less than 90
         days each year. Any advisor to the Company's Board of Directors
         designated by NTB also shall be acceptable to the Company, which
         acceptance shall not be unreasonably withheld and such advisor(s) shall
         each be required to execute an appointment letter representing that
         such advisor will comply with certain responsibilities under the
         federal securities laws with respect to Company information obtained by
         such advisor in the attendance at meetings of the Board of Directors,
         in a form to be agreed between the Company and NTB on the Firm Closing
         Date.

             (x) Upon the exercise of any Warrants after ______________________,
         1997 (13 months after the effective date of the Registration
         Statement), and assuming that the Company desires assistance to solicit
         Warrant exercises, the Company will pay NTB a solicitation fee of 5% of
         the aggregate exercise price of such Warrants which are exercised
         through the efforts and with the assistance of NTB, if (i) the market
         price of the Common

                                      -18-

 
         Stock is greater than the exercise price of such Warrants on the date
         of exercise, (ii) written confirmation by the warrantholder that the
         exercise of the Warrant was solicited by NTB and that NTB is designated
         to receive the solicitation fee, (iii) the Warrant is not held in a
         discretionary account, (iv) disclosure of compensation arrangements has
         been made in documents provided to the warrant holder (such as the
         Prospectus) both as part of the original offering and at the time of
         exercise and (v) the solicitation of the Warrant was not in violation
         of Rule 10b-6 promulgated under the 1934 Act.

             (y) On the Firm Closing Date, the Company shall enter into a
         consulting agreement ("Consulting Agreement"), retaining NTB,
         individually, and not as a Representative of the Underwriters, as
         financial consultant to the Company for a period of 12 months for a fee
         of $30,000 ($2,500 monthly for 12 months) all payable in full on the
         Firm Closing Date. As financial consultant, NTB will advise the Company
         as to market conditions, financial alternatives, resource allocation,
         mergers, acquisition and other business combinations and other
         investment banking services. Such consulting Agreement will also
         provide for such compensation to NTB as shall be agreed between the NTB
         and the Company for varying percentages not to exceed five percent (5%)
         of any consideration paid or received by the Company or the Company's
         shareholders in any transaction (including mergers and acquisitions)
         consummated by the Company in which NTB introduced the other party to
         the Company within 36 months from the Firm Closing Date if such
         transaction is consummated within 36 months from the Firm Closing Date.

         5.  Conditions of Underwriters' Obligations.  The obligations of the
several Underwriters hereunder to purchase and pay for the Units are subject to

additional conditions:

             (a) The Registration Statement and all post-effective amendments
         thereto shall have become effective and all filings required by Rule
         424 and Rule 430A under the 1933 Act shall have been made within the
         time period required by the 1933 Act Regulations prior to the Firm
         Closing Date; no stop order suspending the effectiveness of the
         Registration Statement or any amendment or supplement thereto shall

         Commission for additional information (to be included in the
         Registration Statement or the Prospectus or otherwise) shall have been
         complied with to your satisfaction.

             (b) You shall not have advised the Company that the Registration
         Statement or Prospectus, or any amendment or supplement thereto,
         contains an untrue statement of fact which, in your reasonable opinion,
         is material, or omits to state a fact which, in your reasonable
         opinion, is material and is required to be stated therein or is
         necessary to make

                                      -19-

 
         the statements therein, in light of the circumstances under which they
         were made, not misleading.

             (c) On each Closing Date, there shall have been furnished to you
         the opinion (addressed to you as Representatives) of Chrisman, Bynum &
         Johnson, P.C., Boulder, Colorado, special securities counsel for the
         Company, dated such Closing Date and in form and substance reasonably
         satisfactory to counsel for you and stating that it may be relied upon
         by counsel for the Representatives in giving their opinion, if required
         by you, to the effect that:

                    (i) Each of the Company and its subsidiaries has been duly
                 organized and is validly existing as a corporation in good
                 standing under the laws of Colorado, with full corporate power
                 and authority to own or lease its properties and conduct its
                 business as described in the Prospectus. The Company is duly
                 qualified to do business and is in good standing in each
                 jurisdiction, to the extent the character of the business
                 conducted by it or the location of the properties owned or
                 leased by it makes such qualification necessary, except to the
                 extent that the failure to so qualify does not have a material
                 adverse effect upon the Company.

                    (ii) The authorized, issued and outstanding share capital of
                 the Company is as set forth under the caption "Capitalization"
                 in the Prospectus and the Units, Common Stock, Representatives'
                 Warrants and Underlying Securities conform to the descriptions
                 thereof contained under the captions "Description of
                 Securities" and "Underwriting" in the Prospectus. The offering
                 and sale of securities pursuant to the Prospectus will not
                 violate the rights of any holder of the Company's outstanding
                 securities including its common stock, warrants or options, and
                 all required notices, consents or waivers required with respect
                 to any security holder pursuant to any Registration Right
                 Agreement(s) as referred to in the Prospectus have been given
                 by the parties thereto. The outstanding shares of Common Stock
                 have been, and the Units and each Unit component, upon issuance
                 and delivery and payment therefor in the manner herein
                 described will be duly authorized, validly issued, fully paid
                 and nonassessable. There are no preemptive or, except as
                 described in the Registration Statement, other rights to
                 subscribe for or to purchase from the Company, or any
                 restriction upon the voting or transfer of, any Common Stock
                 pursuant to the Company's Articles of Incorporation or Bylaws,
                 as amended, or, to the best knowledge of such counsel, any
                 agreement or other instrument to which the Company is a party
                 or by which it is bound, except restrictions under applicable
                 securities laws and as provided in Section 4(u) hereof.

                                      -20-

 
                    (iii) To the best of such counsel's knowledge, the Company
                 is not, nor with the giving of notice or lapse of time or both
                 would be, in violation of or in default under, nor will the
                 execution or delivery hereof or of the Representatives' Warrant
                 Agreement or Unit Warrant Agreement or consummation of the
                 transactions contemplated hereby or thereby result in a
                 violation of, or constitute a default under, the Company's
                 Articles of Incorporation or Bylaws, as amended, of the
                 Company, or any material agreement, indenture or other
                 instrument to which the Company is a party or by which it is
                 bound nor will the performance by the Company of its
                 obligations hereunder or under the Representatives' Warrant
                 Agreement or Unit Warrant Agreement violate any law, rule,
                 administrative regulation or decree of any court or any
                 governmental agency or body having jurisdiction over the
                 Company or any of its properties which would have a material
                 and adverse effect, or result in the creation or imposition of
                 any lien, charge, claim or encumbrance, upon any property or
                 asset of the Company.

                    (iv) Each of this Underwriting Agreement, the
                 Representatives' Warrant Agreement, the Unit Warrant Agreement
                 and the Warrants has been duly authorized, executed and
                 delivered by the Company, constitutes the valid and binding
                 agreement of the Company, and is enforceable against the
                 Company in accordance with its terms except insofar as rights
                 to indemnity and/or contribution may be limited by applicable
                 securities laws or the public policy underlying such laws and
                 except as enforcement may be limited by bankruptcy, insolvency,
                 reorganization or other similar laws affecting creditors'
                 rights generally, and be subject to general principles of
                 equity (regardless of whether such enforceability is considered
                 in a proceeding in equity or at law).

                    (v) The Warrant Shares (including those issuable upon
                 exercise of the Representatives' Warrants) and Representatives'
                 Warrant Units have been duly authorized and reserved for
                 issuance and, when issued and delivered in accordance with the
                 terms of this Agreement and the Representatives' Warrant
                 Agreement, respectively, will be duly and validly issued, fully
                 paid and nonassessable.

                    (vi) The certificates representing the Underlying Securities
                 and the Representatives' Warrants are in due and proper form.

                    (vii) The information, if any, required to be set forth in
                 the Registration Statement in answer to Item 9 of Form SB-2
                 (insofar as it relates to such counsel) is to the best of such
                 counsel's knowledge accurately and adequately set forth therein
                 in all material respects.

                                      -21-

 
                    (viii) To the best of such counsel's knowledge, all
                 descriptions in the Prospectus of statutes, regulations, legal
                 or governmental proceedings, contracts and other documents and
                 the description of the consequences to the Company of such
                 laws, proceedings or documents are accurate and fairly present
                 the information required to be shown in all material respects;
                 and such counsel does not know of any statutes, regulations,
                 proceedings, contracts or documents of a character required to
                 be summarized or described in the Prospectus or to be filed as
                 exhibits to the Registration Statement which are not so
                 summarized, described or filed, nor does such counsel know of
                 any pending or threatened litigation or any governmental
                 proceeding, statute or regulation required to be described in
                 the Prospectus which is not so described.

                    (ix) To the best of such counsel's knowledge, the Company
                 owns or has adequate and enforceable rights to use each of the
                 Intangibles (as defined in Section 1(r)) used in connection
                 with the operation of the Company's business, including,
                 without limitation, the Intangibles described or referred to in
                 the Prospectus and any Intangibles incorporated into any
                 product of the Company described in the Prospectus, and all
                 statements with respect to the Intangibles, including
                 statements with respect to products of the Company which
                 incorporate any Intangibles, are accurate and fairly present
                 the information required to be presented in all material
                 respects.

                    (x) To the best of such counsel's knowledge, no holder of
                 any securities of the Company has any right to require
                 registration of shares of Common Stock or other securities of
                 the Company under the 1933 Act, except as any such right may
                 arise under the Representatives' Warrant Agreement and certain
                 Registration Rights Agreements among the Company and the
                 holders of all its outstanding Common Stock as set forth in
                 Part II of the Registration Statement, including any
                 registration rights applicable to any options or warrants
                 heretofore granted by the Company and all rights to require
                 registration in connection with the offering and sale of
                 securities described in the Prospectus, pursuant to the
                 Registration Rights Agreement(s) or any similar agreement to
                 which the Company is a party have been effectively waived by
                 all parties for the applicable periods stated in Section 4(u).
                 The description of the Registration Rights Agreement set forth
                 in the Prospectus is accurate and fairly presents the
                 information required to be shown in all material respects.

                    (xi) The presently outstanding shares of Common Stock of the
                 Company were issued in transactions which were not subject to
                 the registration provisions of the 1933 Act and applicable
                 state securities laws, except that such opinion shall not
                 include an opinion regarding subjective

                                      -22-

 
                 investment intent of purchasers in any private placement. To
                 the best knowledge of such counsel, there is a reasonable basis
                 to conclude that neither the offering nor sale of any presently
                 outstanding shares of Common Stock will be integrated with the
                 offering of the Units for purposes of registration under the
                 Securities Act, or qualification under any state securities
                 laws.

                    (xii) Except for the order of the Commission declaring the
                 Registration Statement effective under the 1933 Act, and except
                 for permits and similar authorizations required under the
                 securities or "blue sky" laws of certain jurisdictions and for
                 such permits and authorizations which have been obtained, no
                 consent, approval, authorization or order of any federal or
                 state court, governmental agency or body is required in
                 connection with the consummation by the Company of the
                 transactions contemplated by this Agreement, the Warrants or
                 the Representatives' Warrant Agreement.

                    (xiii) The Registration Statement and any post-effective
                 amendments thereto have become effective under the 1933 Act
                 and, to the best of such counsel's knowledge, no stop order
                 suspending the effectiveness of the Registration Statement has
                 been issued and, to the best of such counsel's knowledge, no
                 proceedings for that purpose have been instituted or are
                 pending before or threatened by the Commission or any state of
                 the United States or other regulatory body and all filings
                 required by Rule 424 under the 1933 Act in connection with the
                 public offering of the Units have been made within the time
                 periods required; and the Registration Statement and the
                 Prospectus and any amendment or supplement thereto, as of their
                 respective effective dates, comply as to form in all material
                 respects with the requirements of the 1933 Act (except that
                 counsel need express no opinion with respect to the financial
                 statements, management's discussion and analysis or other
                 financial data included therein).

                    (xiv) To the best of such counsel's knowledge, the Company
                 has reasonable grounds to believe that it meets all the
                 requirements for filing on Form SB-2.

                    (xv) The Company is not, and following completion of the
                 offering of the Units and receipt and intended investment of
                 proceeds therefrom as described in the Prospectus, will not be,
                 an "investment company" as defined in the Investment Company
                 Act of 1940, as amended.

                 In rendering the foregoing opinion, counsel may state that such
         opinion is limited to federal and applicable state law, and rely, as to
         matters of fact, upon certificates of responsible officers of the
         Company and on certificates of public

                                      -23-

 
         officials, and may base its opinion upon such reasonable investigations
         and assumptions as shall be set forth in such opinion. In rendering
         such opinion such counsel may rely, to the extent such counsel deems
         proper and to the extent specified in such opinion, if at all, upon an
         opinion or opinions (in form and substance reasonably satisfactory to
         counsel to you) of other counsel familiar with the applicable laws and
         admitted to practice in the applicable jurisdiction. The opinion of
         such counsel for the Company shall state that the opinion of any such
         other counsel is in form satisfactory to such counsel and that in their
         opinion the Representatives and they are justified in relying thereon.
         In addition, such counsel shall state that such counsel has
         participated in conferences with officers and other representatives of
         the Company, representatives of the independent public accountants for
         the Company, representatives of the Representative and counsel for the
         Representative at which the contents of the Registration Statement and
         related matters were discussed and, although such counsel has not
         independently verified, is not passing upon and does not assume any
         responsibility for, the accuracy, completeness or fairness of the
         statements contained in the Registration Statement, no facts have come
         to the attention of such counsel that lead it to believe that the
         Registration Statement, as of the date it is declared effective by the
         Commission, contained an untrue statement of a material fact or omitted
         to state a material fact required to be stated therein or necessary to
         make the statements therein not misleading, or that the Prospectus as
         of the Closing Date includes an untrue statement of a material fact or
         omits to state a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading (it being understood that such counsel need
         not comment as to the financial statements, management's discussion and
         analysis, and other financial data included in the Registration
         Statement, and the Prospectus or the exhibits to the Registration
         Statement).

             (d) There shall have been furnished to you the certificate, dated
         the Closing Date and addressed to you as Representatives, signed by the
         President and Chief Executive Officer and by the Treasurer and Chief
         Financial Officer of the Company, to the effect that (i) the
         representations and warranties of the Company contained in Section 1 of
         this Agreement are true and correct as if made at and as of such
         Closing Date, and the Company has complied with all the agreements and
         satisfied all the conditions on its part to be performed or satisfied
         at or prior to such Closing Date; (ii) no stop order suspending the
         effectiveness of the Registration Statement has been issued, and no
         proceedings for that purpose to their knowledge have been initiated or
         threatened; (iii) the signers of said certificate have carefully
         examined the Registration Statement and the Prospectus, and any
         amendments or supplements thereto, and such documents contain all
         statements and information required to be included therein, and do not
         include any untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading; and (iv) since the effective date of
         the Registration Statement, there

                                      -24-

 
         has occurred no event required to be set forth in an amendment or
         supplement to the Registration Statement or the Prospectus which has
         not been so set forth.

             (e) Since the effective date of the Registration Statement under
         the 1933 Act, the Company shall not have sustained any loss by fire,
         flood, accident or other calamity, nor shall it have become a party to
         or the subject of any litigation, individually or in the aggregate,
         which is materially adverse to the Company, nor shall there have been a
         material adverse change in the general affairs, business, key
         personnel, capitalization, financial position or net worth of the
         Company, whether or not arising in the ordinary course of business,
         which loss, litigation or change, in your reasonable judgment, shall
         render it inadvisable to proceed with the delivery of the Units.

             (f) On the date of this Agreement and on each Closing Date, Ernst &
         Young shall have furnished to the Representatives a letter or letters
         dated respectively as of the date of this Agreement and as of each
         Closing Date, in form and substance satisfactory to the
         Representatives, confirming that they are independent accountants
         within the meaning of the 1933 Act and the applicable 1933 Act
         Regulations and stating in effect that:

                    (i) in their opinion the audited financial statements and
                 financial statement schedules included in the Registration
                 Statement and Prospectus and reported on by them comply in form
                 in all material respects with applicable accounting
                 requirements of the 1933 Act and the 1933 Act Regulations;

                    (ii) on the basis of a reading of the latest unaudited
                 financial statements made available by the Company; their
                 limited review in accordance with standards established by the
                 American Institute of Certified Public Accountants of the
                 unaudited interim financial information for the 3 month period
                 ended March 31, 1996, and as at March 31, 1996, carrying out
                 certain specified procedures (but not an examination in
                 accordance with generally accepted auditing standards) which
                 would not necessarily reveal matters of significance with
                 respect to the comments set forth in such letter; a reading of
                 the minutes of the meetings of the stockholders, directors and
                 audit and compensation committees of the Company; and inquiries
                 of certain officials of the Company who have responsibility for
                 financial and accounting matters of the Company as to
                 transactions and events subsequent to December 31, 1995,
                 nothing came to their attention which caused them to believe
                 that:

                         A. any unaudited financial statements included in the
                         Registration Statement and the Prospectus do not comply
                         in form in all material respects with applicable
                         accounting requirements of the 1933 Act and with the
                         1933 Act

                                      -25-

 
                         Regulations with respect to registration statements on
                         Form SB-2; and said unaudited financial statements are
                         not in conformity with generally accepted accounting
                         principles applied on a basis substantially consistent
                         with that of the audited financial statements included
                         in the Registration Statement and the Prospectus; and


                         B. with respect to the period subsequent to March 31,
                         1996, there were any changes, at a specified date not
                         more than five business days prior to the date of the
                         letter, in the long-term debt of the Company or capital
                         stock of the Company or decreases in the stockholders'
                         equity of the Company or decreases in working capital,
                         total assets, income from operations or gross profit of
                         the Company as compared with the amounts shown on the
                         March 31, 1996 balance sheet included in the
                         Registration Statement and the Prospectus or for the
                         period from March 31, 1996 to such specified date there
                         were any decreases, as compared with the amounts shown
                         in the balance sheet at December 31, 1995 included in
                         the Prospectus, in net revenues or income before income
                         taxes or in total or per share amounts of net income of
                         the Company except in all instances for changes or
                         decreases set forth in such letter, in which case the
                         letter shall be accompanied by an explanation by the
                         Company as to the significance thereof unless said
                         explanation is not deemed necessary by the
                         Representatives; and

                    (iii) they have performed certain other specified procedures
                 as a result of which they determined that certain information
                 of an accounting, financial or statistical nature (which is
                 limited to accounting, financial or statistical information
                 derived from the general accounting records of the Company) set
                 forth in the Registration Statement and the Prospectus,
                 including the information set forth under the captions "Summary
                 Financial Information", "Risk Factors", "Dilution",
                 "Capitalization", "Selected Financial Data", "Management
                 Discussion and Analysis of Financial Condition and Results of
                 Operations", "Business" and "Management" in the Prospectus,
                 agrees with the accounting records of the Company excluding any
                 questions of legal interpretation.

                    References to the Prospectus in this paragraph (f) include
                 any supplement thereto at the date of the letter.

                                      -26-

 
                    The Representatives shall have also received from Ernst &
                 Young a letter stating that the Company's system of internal
                 accounting controls, taken as a whole, is sufficient to meet
                 the broad objectives of internal accounting control insofar as
                 those objectives pertain to the prevention or detection of
                 errors or irregularities in the amounts that would be material
                 in relation to the financial statements of the Company.

             (g) Subsequent to the date of this Agreement or, if earlier, the
         dates as of which information is given in the Registration Statement
         (exclusive of any amendment thereof) and the Prospectus (exclusive of
         any supplement thereto), there shall not have been (i) any change or
         decrease specified in the letter or letters referred to in paragraph
         (f) of this Section 5 or (ii) any change, or any development involving
         a prospective change, in or affecting the business or properties of the
         Company the effect of which, in any case referred to in clause (i) or
         (ii) above, is, in the judgment of the Representatives, so material and
         adverse as to make it impractical or inadvisable to proceed with the
         offering or delivery of the Units as contemplated by the Registration
         Statement (exclusive of any amendment thereof) and the Prospectus
         (exclusive of any supplement thereto).

             (h) On or prior to the date of this Agreement, the NASD shall have
         approved the Underwriters' participation and the distribution of the
         Units to be sold pursuant to the Registration Statement and the
         Prospectus.

             (i) The Units, the Common Stock and the Warrants shall have been
         designated for quotation on NASDAQ Small Cap, and, in each case,
         subject only to notice of issuance.

             (j) At or prior to the Firm Closing Date, the Representatives'
         Warrant Agreement shall have been entered into by the Company and you,
         and the Representatives' Warrants shall have been issued and sold to
         you pursuant to the Representatives' Warrant Agreement.

             (k) At or prior to the Firm Closing Date, you shall have received
         the written agreements and representations described in Section 4(u),
         (w), and (y) hereof.

             (l) Prior to the Firm Closing Date, the Company shall have
         furnished to the Representatives such further information, certificates
         and documents as the Representatives may reasonably request.

             If any of the conditions specified in this Section 5 shall not have
         been fulfilled in all material respects when and as provided in this
         Agreement, or if any of the opinions and certificates mentioned above
         or elsewhere in this Agreement shall not be in all material respects
         reasonably satisfactory in form and substance to the Representatives
         and counsel for the Representatives, this Agreement and all obligations
         of the Underwriters hereunder may be canceled at, or at any time prior
         to, the Firm Closing Date by the Representatives. Notice

                                      -27-

 
         of such cancellation shall be given to the Company in writing, or by
         telephone or facsimile and confirmed in writing.

     6.  Indemnification and Contribution.

             (a) The Company shall indemnify and hold harmless each Underwriter,
         each of their respective officers, directors, partners, employees,
         agents and counsel, and each person, if any, who controls any
         Underwriter within the meaning of Section 15 of the 1933 Act or Section
         20(a) of the 1934 Act, against any loss, claim, damage or liability (or
         any action in respect thereof), joint or several, to which such
         Underwriter may become subject, under the 1933 Act or otherwise,
         insofar as such loss, claim, damage or liability (or action with
         respect thereto) arises out of or is based upon (i) any untrue
         statement or alleged untrue statement of a material fact made by the
         Company in Section 1 hereof, or (ii) any untrue statement or alleged
         untrue statement of a material fact contained (A) in the Prospectus or
         any amendment or supplement thereto, or (B) in any application or other
         document executed by the Company specifically for that purpose or based
         upon written information furnished by the Company filed with any state
         or other jurisdiction in order to qualify any or all of the Units or
         other securities under the securities laws thereof or with the
         Commission or securities regulatory authority or securities exchange
         (any such application, document or information being hereinafter called
         a "Application"), or (iii) the omission or alleged omission to state in
         the Registration Statement, any Preliminary Prospectus or the
         Prospectus or any amendment or supplement thereto or in any Application
         a material fact required to be stated therein or necessary to make the
         statements therein not misleading; and shall, promptly upon request,
         reimburse each Underwriter for any reasonable legal or reasonable other
         expenses as incurred by such Underwriter in connection with
         investigating, preparing to defend, or defending against or appearing
         as a third-party witness in connection with any such loss, claim,
         damage, liability or action, notwithstanding the possibility that
         payments for such expenses might later be held to be improper, in which
         case the person receiving them shall promptly refund them; provided,
         however, that the Company shall not be liable in any such case to the
         extent, but only to the extent, that any such loss, claim, damage or
         liability arises out of or is based upon an untrue statement or alleged
         untrue statement or omission or alleged omission made in reliance upon
         or in conformity with written information furnished to the Company
         through you by or on behalf of any Underwriter specifically for use in
         the preparation of the Registration Statement, any Preliminary
         Prospectus, the Prospectus or any amendment or supplement thereto, or
         any Blue Sky Application; and provided further, that with respect to
         any untrue statement or omission or alleged untrue statement or
         omission made in any Preliminary Prospectus, the indemnity agreement
         contained in this paragraph shall not inure to the benefit of any
         Underwriter from whom the person asserting any such losses, claims,
         damages, liabilities or expenses purchased the Units concerned (or to
         the benefit of any person controlling such Underwriter) to the extent
         that any such loss, claim, damage, liability or expense of such
         Underwriter or controlling person results from the fact that a copy of
         the Prospectus was not sent or given to such person at or prior to the
         written confirmation of sale of such Units as required by the 1933 Act,
         and if the untrue statement

                                      -28-

 
         or omission has been corrected in the Prospectus, unless such failure
         to deliver the Prospectus was a result of noncompliance by the Company
         with its obligations under Section 4(c) hereof.


             (b) Each Underwriter severally, but not jointly, shall indemnify
         and hold harmless the Company, each of its directors, each nominee (if
         any) for director named in the Prospectus, each of its officers who has
         signed the Registration Statement and each person who controls the
         Company within the meaning of Section 15 of the 1933 Act or Section
         20(a) of the 1934 Act, against any loss, claim, damage or liability (or
         any action in respect thereof) to which the Company or any such
         director, nominee, officer or controlling person may become subject,
         under the 1933 Act or otherwise, insofar as such loss, claim, damage or
         liability (or action with respect thereof) arises out of or is based
         upon (i) any claim which results from failure to send or give a copy of
         the Prospectus to an investor at or prior to the written confirmation
         of sale of Units at any time when the Company shall have delivered
         sufficient Prospectuses to the Underwriters to effect distribution of
         such Prospectus (ii) any untrue statement or alleged untrue statement
         of a material fact contained (A) in the Registration Statement, any
         Preliminary Prospectus or the Prospectus or any amendment or supplement
         thereto, or (B) in any Application, or (iii) the omission or alleged
         omission to state in the Registration Statement, any Preliminary
         Prospectus or the Prospectus or any amendment or supplement thereto or
         in any Application a material fact required to be stated therein or
         necessary to make the statements therein, in light of the circumstances
         under which they were made, not misleading, except that such
         indemnification shall be available in each such case to the extent, but
         only to the extent, that such untrue statement or alleged untrue
         statement or omission or alleged omission was made in reliance upon or
         in conformity with written information furnished to the Company by such
         Underwriter specifically for use in the preparation thereof; and shall
         reimburse any legal or other expenses as and when reasonably incurred
         by the Company or any such other indemnified person in connection with
         investigating, defending against, settling, compromising or paying any
         such loss, claim, damage, liability or action.

             (c) Promptly after receipt by an indemnified party under subsection
         (a) or (b) above of notice of any claim or the commencement of any
         action, the indemnified party shall, if a claim with respect thereto is
         to be made against the indemnifying party under such subsection, notify
         the indemnifying party in writing of the claim or the commencement of
         that action; and the failure to notify the indemnifying party shall not
         relieve it from any liability that it may have to an indemnified party
         otherwise than under such subsection. If any such claim or action is
         brought against an indemnified party, the indemnifying party shall be
         entitled to participate therein and, to the extent that it wishes,
         jointly with any other similarly notified indemnifying party, to assume
         the defense thereof with counsel reasonably satisfactory to the
         indemnified party. After notice from the indemnifying party to the
         indemnified party of its election to assume the defense of such claim
         or action, the indemnifying party shall not be liable to the
         indemnified party under such subsection for any legal or other expenses
         subsequently incurred by the indemnified party in connection with

                                      -29-

 
         the defense thereof other than reasonable costs of investigation,
         except that you shall have the right to employ counsel to represent you
         and those other Underwriters who may be subject to liability arising
         out of any claim with respect to which indemnity may be sought by the
         Underwriters against the Company under such subsection if, in your
         reasonable judgment, it is advisable for you and those Underwriters to
         be represented by separate counsel, and in that event the reasonable
         legal fees and expenses of one such separate counsel shall be paid by
         the Company.

             (d) If the indemnification provided for in this Section 6 is
         unavailable or insufficient to hold harmless an indemnified party under
         subsection (a) or (b) above, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party as a
         result of the losses, claims, damages or liabilities referred to in
         subsection (a) or (b) above (i) in such proportion as is appropriate to
         reflect the relative benefits received by the Company and the
         Underwriters from the offering of the Units, or (ii) if the allocation
         provided by clause (i) above is not permitted by applicable law, in
         such proportion as is appropriate to reflect not only the relative
         benefits referred to in clause (i) above but also the relative fault of
         the Company and the Underwriters in connection with the statements or
         omissions that resulted in such losses, claims, damages or liabilities,
         as well as any other relevant equitable considerations. The relative
         respective benefits received by the Company and the Underwriters shall
         be deemed to be in the same proportion that the total net proceeds from
         the offering of the Units (before deducting expenses other than the
         non-accountable expense allowance) received by the Company and the 
         total underwriting discounts and commissions received by the
         Underwriters bear to one another. The relative fault shall be
         determined by reference to, among other things, whether the untrue or
         alleged untrue statement of a material fact or the omission or alleged
         omission to state a material fact relates to information supplied by
         the Company or the Underwriters and the parties' relative intent,
         knowledge, access to information and opportunity to correct or prevent
         such untrue statement or omission. The Company and the Underwriters
         agree that it would not be just and equitable if contributions pursuant
         to this subsection (d) were to be determined by pro rata allocation or
         by any other method of allocation which does not take into account the
         equitable considerations referred to in the first sentence of this
         subsection (d). The amount paid by an indemnified party as a result of
         the losses, claims, damages or liabilities referred to in this
         subsection (d) shall be deemed to include any legal or other expenses
         reasonably incurred by such indemnified party in connection with
         investigating or defending against any action or claim which is the
         subject of this subsection (d). Notwithstanding the provisions of this
         subsection (d), no Underwriter shall be required to contribute any
         amount in excess of the amount by which the total price at which the
         Units underwritten by it and distributed to the public exceeds the
         amount of any damages that such Underwriter has otherwise been required
         to pay by reason of such untrue or alleged untrue statement or omission
         or alleged omission. No person guilty of fraudulent misrepresentation
         (within the meaning of Section 11(f) of the 1933 Act) shall be entitled
         to contribution from any person who was not guilty of such fraudulent
         misrepresentation. The Underwriters' obligations in this subsection (d)
         to contribute are several in proportion to their respective
         underwriting obligations and are

                                      -30-

 
         not joint. Each party entitled to contribution agrees that upon the
         service of a summons or other initial legal process upon it in any
         action instituted against it with respect to which contribution may be
         sought, it shall promptly give written notice of such service to the
         party or parties from whom contribution may be sought, but the omission
         so to notify such party or parties of any such service shall not
         relieve the party from whom contribution may be sought from any
         obligation it may have hereunder or otherwise (except as specifically
         provided in Section 6(c) above).

             (e) The obligations of the Company under this Section 6 shall be in
         addition to any liability that the Company may otherwise have, and
         shall extend, upon the same terms and conditions, to each person, if
         any, who controls any Underwriter within the meaning of Section 15 of
         the Securities Act or Section 20(a) of the 1934 Act, and the
         obligations of each Underwriter under this Section 6 shall be in
         addition to any liability that such Underwriter may otherwise have, and
         shall extend, upon the same terms and conditions, to each director of
         the Company (including any person who, with his consent, is named in
         the Registration Statement as about to become a director of the
         Company), to each officer of the Company who has signed the
         Registration Statement and to each person, if any, who controls the
         Company within the meaning of Section 15 of the 1933 Act or Section
         20(a) of the 1934 Act.

         7. Substitution of Underwriters. If on any Closing Date any Underwriter
defaults in its obligation to purchase the number of Units which it has agreed
to purchase hereunder, the non-defaulting Underwriters shall be obligated to
purchase (in the respective proportions which the number of Firm Units set forth
opposite the name of each non-defaulting Underwriter in Schedule I hereto bears
to the total number of Firm Units set forth opposite the names of all of the
non-defaulting Underwriters in Schedule I hereto) the Units which the defaulting
Underwriter agreed but failed to purchase on such Closing Date, except that the
non-defaulting Underwriters shall not be obligated to purchase any of the Units
if the total number of Units on such Closing Date which the defaulting
Underwriter or Underwriters agreed but failed to purchase exceeds 10% of the
total number of Units to be purchased on such Closing Date, and any non-
defaulting Underwriter shall not be obligated to purchase more than 110% of the
number of Units which it agreed to purchase on such Closing Date pursuant to the
terms of Section 2 hereof. If the foregoing maximums are exceeded, the non-
defaulting Underwriters, and any other underwriters satisfactory to you who so
agree, shall have the right, but shall not be obligated, to purchase (in such
proportions as may be agreed upon among them) all the Units to be purchased on
such Closing Date; and if the non-defaulting Underwriters and any other
underwriters satisfactory to you do not elect to purchase the Units that the
defaulting Underwriter or Underwriters agreed but failed to purchase, this
Agreement shall terminate without liability on the part of any non-defaulting
Underwriter or the Company except for the payment of expenses to be borne by the
Company and the Underwriters as provided in Section 4(i) hereof and the
indemnity and contribution agreements of the Company and the Underwriters
contained in Section 6 hereof.

     Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have for damages caused by its default.  If the other
underwriters satisfactory to you are obligated or agree 

                                      -31-

 
to purchase the Units of a defaulting Underwriter, either you or the Company may
postpone the Firm Closing Date for up to seven full Business Days in order to
effect any changes that may be necessary in the Registration Statement, the
Prospectus or in any other document or agreement, and to file promptly any
amendments or any supplements to the Registration Statement or the Prospectus
which in your reasonable opinion may thereby be made necessary.

     8.  Effective Date and Termination.

             (a) This Agreement shall become effective at 11:00 A.M., Denver,
         Colorado time, on the earlier of (i) the first full Business Day
         following the date the Registration Statement becomes effective, or
         (ii) at such time after the Registration Statement becomes effective as
         you shall release the Firm Units for sale to the public. You shall
         notify the Company and its counsel immediately after you have taken any
         action that causes this Underwriting Agreement to become effective.
         Until this Agreement is effective, it may be terminated by the Company
         by giving notice as hereinafter provided to you or by you by giving
         notice as hereinafter provided to the Company, except that the
         provisions of Sections 4(i) and 6 hereof shall at all times be
         effective. For purposes of this Agreement, the release of the Firm
         Units for sale to the public shall be deemed to have been made when you
         release, by telegram or otherwise, firm offers of the Firm Units to
         securities dealers or release for publication a newspaper advertisement
         relating to the Firm Units, whichever occurs first.

             (b) This Agreement shall be subject to termination by you (subject,
         however, to your undertakings with the NASD) by giving notice to the
         Company prior to the delivery of and payment for the Units, if prior to
         such time (i) the Company shall have failed, refused or been unable to
         perform any agreement on its part to be performed hereunder unless
         compliance therewith or performance or satisfaction thereof shall have
         been expressly waived in writing by the Representatives; (ii) any other
         condition of the obligations of the Underwriters hereunder is not
         fulfilled; (iii) there shall have occurred any material adverse change,
         since the respective dates as of which information is given in the
         Prospectus, in or affecting the business or financial condition of the
         Company or the Company's earnings, business affairs, management or
         prospects of the Company, whether or not arising in the ordinary course
         of its business; (iv) there shall have occurred an outbreak of major
         hostilities (or an escalation thereof) in which the United States is
         involved, a declaration by the United States of a national emergency or
         war or other calamity or crisis the effect of which on financial
         markets is such as to result, in your judgment, in a material
         impairment of this Agreement by making it impracticable or inadvisable
         to proceed with the offering or delivery of the Units as contemplated
         by the Prospectus (exclusive of any supplement thereto); (v) there
         shall have occurred suspension of trading in securities on the New York
         Stock Exchange, the American Stock Exchange or the NASDAQ market system
         or minimum or maximum prices shall have been established on either of
         said Exchange or market system; (vi) a banking moratorium shall have
         been declared by federal or state authorities; (vii) there shall have
         occurred any action by any federal, state or local government or agency
         in respect to monetary or fiscal affairs or regulations affecting 
         health care delivery or the health care

                                      -32-

 
         claims process which in the reasonable opinion of the Representatives
         have a material adverse effect on the securities markets in the United
         States or the business prospects of the Company or business generally;
         or

             (c) This Agreement also may be terminated as provided in Section 5.

             (d) Any termination of this Agreement pursuant to this Section 8
         shall be without liability on the part of the Company or the
         Underwriters, except as otherwise provided in Sections 4(i) and 6
         hereof.

             Any notice referred to in Section 8 above may be given at the
         address specified in Section 10 hereof in writing or by facsimile or
         telephone; and if by facsimile or telephone, shall be immediately
         confirmed in writing.

     9.  Survival of Indemnities, Contribution, Warranties and Representations.
The indemnity and contribution agreements contained in Section 6 and the
representations, warranties and covenants of the Company in Sections 1 and 4
shall survive the delivery of the Units to the Underwriters hereunder and shall
remain in full force and effect, regardless of any termination or cancellation
of this Agreement or any investigation made by or on behalf of any indemnified
party or any party to the contribution provisions of Section 6(d).

     10. Notices.   Except as otherwise provided in this Agreement, (a)
whenever notice is required by the provisions hereof to be given to the Company,

     11. Representations and Warranties and Information Furnished by
Underwriters.  Each Representative, for itself and on behalf of the several
Underwriters, represents and warrants (and the Company acknowledges) that the
statements set forth in the table on the front cover page with respect to
underwriting discounts, the paragraph on or about the inside front cover page
with respect to stabilization, and under the caption "Underwriting" in any
Preliminary Prospectus and in the Prospectus (except for statements made under
the caption "Underwriting" in any such Prospectus relating to sales or
dispositions by the Company and the Company's undertakings), constitute the

                                      -33-

 
only written information furnished by or on behalf of the Underwriters referred
to in paragraphs (b) and (c) of Section 1 hereof and in paragraphs (a) and (b)
of Section 6 hereof, and are true and correct in all material respects. The
Representatives further represent and warrant that they have been authorized by
each of the several Underwriters as Representatives to enter into this
Underwriting Agreement on its behalf and to act in the matter herein provided.

     12.  Parties.   This Agreement is made solely for the benefit of the
several Underwriters, the Company, and any officer, director or controlling
person referred to in Section 6 hereof, and their respective successors and
assigns, and, except as provided in Section 15 of this Agreement, no other
person shall acquire or have any right by virtue of this Agreement.  The term
"successors and assigns," as used in this Agreement, shall not include any
purchaser of any of the Units from the Underwriters.  You shall act on behalf of
each of the several Underwriters and the Company shall be entitled to act and
rely upon any statement, request, notice or agreement on behalf of each of the
several Underwriters if the same shall have been made or given in writing by
you.

     13.  Definition of "Business Day".   For purposes of this Agreement,
"Business Day" means any day on which the New York Stock Exchange, Inc. is open
for trading.

     14.  Governing Law.   This Agreement shall be governed by and construed in
accordance with the laws of the State of Colorado without giving effect to the
choice of law or conflict of laws, principles or rules thereof.

     15. Submission to Jurisdiction and Waiver of Inconvenient Forum. The
Company, by the execution and delivery of this Underwriting Agreement,
designates and appoints CT Corporation System as the authorized agent of the
Company upon whom process may be served in any suit, proceeding or other action
which is brought against the Company in any United States federal or state court
sitting in the City and County of Denver, State of Colorado, and which relates
to or arises out of this Underwriting Agreement or the offering of the Units
hereunder and the Company expressly accepts jurisdiction of any such court in
respect of any such suit, proceeding or other action and, without limiting other
methods of obtaining jurisdiction, expressly submits to exclusive personal
jurisdiction of any such court in respect of any such suit, proceeding or other
action. Such designation and appointment shall be irrevocable, unless and until
a successor authorized agent in the City and County of Denver, State of Colorado
reasonably acceptable to you shall have been appointed by the Company, such
successor shall have accepted such appointment and written notice thereof shall
have been given to you. The Company further agrees that service of process upon
its authorized agent or successor (and written notice of said service to the
Company, given as provided in Section 10 above) shall be deemed in every respect
personal service of process upon the Company in any such suit, proceeding or
other actions. (For the Company's convenience only and not for the purposes of
service of process or effecting personal jurisdiction in any such suit,
proceeding or other action, copies of such process shall also, if practicable,
be mailed to the notice parties set forth in Section 10 of this agreement if
Neidiger, Tucker, Bruner, Inc. shall be the party serving such process on giving
such notice.) The Company hereby irrevocably waives any objection that it may
have or hereafter have to the laying of venue of any such action or proceeding
arising out

                                      -34-

 
of or based on the Units, or this Agreement or otherwise relating to
the offering, issuance and sale of the Units in any federal or state court
sitting in City and County of Denver and State of Colorado and hereby further
irrevocably waives any claim that any such action or proceeding in any such
court has been brought in an inconvenient forum.  The Company agrees that any
final judgment after exhaustion of all appeals or the expiration of time to
appeal in any such action or proceeding arising out of the sale of the Units or
this Agreement rendered by any such federal court or state court shall be
conclusive, and may be enforced in any other jurisdiction by suit on the
judgment or in any other manner provided by law.  Nothing contained in this
Agreement shall affect or limit the right of any Underwriter to serve any
process or notice of motion or other application in any other manner permitted
by law or limit or affect the right of any Underwriter to bring any action or
proceeding against the Company or any of its property in the courts of any other
jurisdiction.  The Company further agrees to take any and all action, including
the execution and filing of all such instruments and documents, as may be
necessary to continue such designation and appointment or such substitute
designation and appointment in full force and effect.  The Company hereby agrees
to the exclusive jurisdiction of the courts of the State of Colorado, or the
federal courts sitting in the City and County of Denver, State of Colorado in
connection with any action brought by it relating to this Agreement or the
offering of the Units hereunder.

     The provisions of this Section 15 are also intended to benefit those
persons who acquire the Firm Units and the Option Units from the Underwriters.

     16.  Counterparts.   This Underwriting Agreement may be signed in two or
more counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement.

                                      -35-

 
     Please confirm, by signing and returning to us counterparts of this
Agreement, that you are acting on behalf of yourself and the several
