                      PREFERRED STOCK PURCHASE AGREEMENT


          PREFERRED STOCK PURCHASE AGREEMENT dated May 8, 2000 (the "Agreement")

Morgan Investment Corporation, Sixty Wall Street SBIC Fund, L.P., First Union
Capital Partners, Inc., Meritage Private Equity Fund, L.P., Meritage Private
Equity Parallel Fund, L.P., Meritage Entrepreneurs Fund, L.P., and Stolberg,

          1.   Purchase and Sale of Stock.
               --------------------------

               1.1  Sale and Issuance of Series C Preferred Stock.
                    ---------------------------------------------

                    (a)  Prior to the date hereof, the Company has adopted and
filed with the Secretary of State of Delaware the Third Amended and Restated
Certificate of Incorporation in the form attached hereto as Exhibit A (the
                                                            ---------
"Restated Certificate").

                    (b)  Subject to the terms and conditions of this Agreement,
each Investor agrees, severally but not jointly, to purchase from the Company at
the Closing, and the Company agrees to sell and issue to each Investor at the
Closing, that number of shares of the Company's Series C Preferred Stock set
forth opposite such Investor's name on Schedule A hereto for the purchase price
                                       ----------
of $22.00 per share.

               1.2  Closing. The purchase and sale of the Series C Preferred
                    -------
Stock shall take place at the Company's offices located at 938 Bannock Street,
Suite 300, Denver, Colorado 80204 at 10:00 a.m. on May 8, 2000, or at such other
time and place as the Company and the Investors mutually agree upon orally or in
writing (which time and place are designated as the "Closing"). At the Closing,
the Company shall deliver to each Investor a certificate representing the Series
C Preferred Stock that such Investor is purchasing against payment of the
purchase price therefor by wire transfer of immediately available funds.

               1.3  Subsequent Sale of Series C Preferred Stock. The Company may
                    -------------------------------------------
sell up to an additional 2,022,727 shares of Series C Preferred Stock at a price
of not less than $22.00 per share (and otherwise on substantially identical
terms) prior to June 22, 2000 to one or more additional purchasers selected by
the Company. Any such additional purchaser shall execute a purchase agreement in
substantially the form of this Agreement and shall become a party to the Third
Amended and Restated Investors' Rights Agreement in the form attached hereto as
Exhibit B (the "Investors' Rights Agreement") and the Third Amended and Restated
---------
Stockholders' Agreement in the form attached hereto as Exhibit C (the
                                                       ---------
"Stockholders' Agreement"). Notwithstanding the foregoing, and subject to the
following sentences, in the event that the Company issues additional shares of
Series C Preferred Stock at a price per share less than $22.00 per share (the
"Lower Price") prior to June 22, 2000, the Company shall concurrently issue to
each Investor (the "Additional Series C Shares"), for no additional
consideration, that number of additional shares of Series C Preferred Stock that
such Investor
<PAGE>

would have received had it purchased shares pursuant to this Agreement at the
Lower Price. Any Additional Series C Shares issued pursuant to this Section 1.3
shall be treated as if they were issued at the Closing, and the Company and the
Investors shall use their best efforts to amend the Company's Restated
Certificate to (a) reduce the "Original Series C Issue Price" and the "Series C
Conversion Price" (as such terms are defined therein) to equal such Lower Price
and (b) if necessary, authorize the issuance of additional Series C Preferred
Stock in order to issue the Investors the Additional Series C Shares. The
Investors acknowledge that any issuance of Additional Series C Shares pursuant
to this Section 1.3 is intended to make the Investors whole for the issuance of
shares of Series C Preferred Stock by the Company prior to June 22, 2000, and
shall be in lieu of any anti-dilution protection otherwise applicable under the
Company's Restated Certificate.

               1.4  Post-Closing Obligations. In the event that, at any time,
                    ------------------------
the Company's representation and warranty in Section 2.2 is determined not to
have been true when made, the Company shall promptly issue to the Investors, on
a pro rata basis as an adjustment to the purchase price paid for the shares of
Series C Preferred Stock purchased hereunder and without the payment of
additional consideration by the Investors, an additional number of shares of
Series C Preferred Stock such that each Investor would own the same economic
interest and voting power as it would have owned had such representation and
warranty been true and correct in all respects when made. If at the time of an
adjustment pursuant to the preceding sentence any shares of Series C Preferred
Stock purchased hereunder have been converted into Common Stock, the Company
shall issue additional shares of Common Stock with respect to such converted
shares of Series C Preferred Stock based on the conversion ratio that would have
been in effect if such shares had remained outstanding. Any additional shares
issued pursuant to this Section 1.4 shall be treated as if they were issued at
the Closing and shall reflect any anti-dilution adjustments arising from the
date of Closing through the date of such issuance. Concurrently with each such
issuance, the Company shall pay or accrue all dividends or other distributions
which would have been paid or accrued with respect to such additional shares
from the date of Closing through the date of such issuance.

          2.   Representations and Warranties of the Company. The Company hereby
               ---------------------------------------------
represents and warrants to each Investor that, except as set forth on the
Schedule of Exceptions (the "Schedule of Exceptions") attached hereto as
Schedule B, which exceptions shall be deemed to be representations and
----------
warranties as if made hereunder:

               2.1  Organization, Good Standing, Power and Qualification. The
                    ----------------------------------------------------
Company is a corporation duly organized, validly existing and in good standing
under the laws of the State of Delaware. The Company has all requisite corporate
power and authority to own and operate its property, to lease the property it
operates as lessee and to conduct the business in which it is currently, or is
currently proposed to be, engaged and has the power and authority to execute,
deliver and perform its obligations under this Agreement, the Investors' Rights
Agreement and the Stockholders' Agreement. The Company is duly qualified to
transact business and is in good standing in each jurisdiction in which the
failure to so qualify would have a material adverse effect on the business,
assets or financial condition of the Company (an "MAE").

               2.2  Capitalization and Voting Rights. (a) The authorized, issued
                    --------------------------------
and outstanding capital stock of the Company will consist immediately prior to
the Closing of:

                         (i)   Preferred Stock. 13,720,000 shares of Preferred
                               ---------------
     Stock, par value $0.001 (the "Preferred Stock"), of which (i) 3,310,000
     shares have been designated Series A Preferred Stock (the "Series A
     Preferred Stock"), of which 3,309,953 shares are outstanding, (ii)
     7,000,000 shares have been designated Series B Preferred Stock (the "Series
     B Preferred Stock"), of which 6,896,552 shares are outstanding and (iii)
     3,410,000 shares have been designated Series C Preferred Stock (the "Series
     C Preferred Stock"), of which none are outstanding. The rights, privileges
     and preferences of the Series A, Series B, and Series C Preferred Stock are
     as stated in the Restated Certificate.

                         (ii)  Common Stock. 36,280,000 shares of common stock,
                               ------------
     par value $0.001 ("Common Stock"), of which 3,657,630 shares are issued and
     outstanding.

                    (b)  The outstanding shares of Series A and Series B
Preferred Stock and Common Stock are owned by the stockholders and in the
numbers specified in Exhibit D hereto.
                     ---------

                    (c)  The outstanding shares of Series A and Series B
Preferred Stock and Common Stock are all duly and validly authorized and issued,
fully paid and nonassessable, and were issued in compliance with all applicable
state and federal laws concerning the issuance of securities.

                    (d)  Except for (A) the conversion privileges of the Series
A, Series B and Series C Preferred Stock, (B) the rights provided in Section 3
of the Stockholders' Agreement, and (C) 1,004,420 options outstanding as of
April 30, 2000, and such other options which have been granted in the ordinary
course by the Company since such date to purchase shares of the Company's Common
Stock pursuant to the Company's 1997 Stock Option Plan, as amended (the "Option
Plan"), which Option Plan authorizes the grant of options to purchase up to
2,685,000 shares of the Company's Common Stock, there are no outstanding
options, warrants, rights (including conversion or preemptive rights) or
agreements for the purchase or acquisition from the Company of any shares of its
capital stock. The Company also expects to grant warrants to purchase up to
250,000 shares of Common Stock to a lender or financial institution in
connection with a new credit facility. The Company is not a party or subject to
any agreement or understanding which affects or relates to the voting or giving
of written consents with respect to any security or other ownership interest in
the Company or by a director of the Company.

                    (e)  The issuance by the Company of 3,409,091 shares of
Series C Preferred Stock as of the date hereof would constitute approximately
17.38% of the Company's outstanding capital stock, calculated on a fully diluted
basis.

               2.3  Subsidiaries. The Company does not presently own or control,
                    ------------
directly or indirectly, any interest in any other corporation, association, or
other business entity,

                                       3
<PAGE>

except for the subsidiaries listed on Exhibit F attached hereto. The Company is
not a participant in any joint venture, partnership, or similar arrangement.

               2.4  Authorization. All corporate action on the part of the
                    -------------
Company, its officers, directors and stockholders necessary for the
authorization, execution and delivery of this Agreement, the Investors' Rights
Agreement, and the Stockholders' Agreement, the performance of all obligations
of the Company hereunder and thereunder, and the authorization (or, in the case
of the Common Stock, reservation for issuance), sale and issuance of the Series
C Preferred Stock being sold hereunder and the Common Stock issuable upon
conversion of the Series C Preferred Stock has been taken or will be taken prior
to the Closing. This Agreement, the Investors' Rights Agreement, and the
Stockholders' Agreement constitute valid and legally binding obligations of the
Company, enforceable in accordance with their respective terms, except (i) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium and
other laws of general application affecting enforcement of creditors' rights
generally, (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies, and (iii) to the
extent the indemnification provisions contained in the Investors' Rights
Agreement may be limited by applicable federal or state securities laws.

               2.5  Valid Issuance of Preferred and Common Stock. The Series C
                    --------------------------------------------

consideration expressed herein, will be duly and validly issued, fully paid and
nonassessable, free and clear of all liens and other encumbrances and will be
free of restrictions on transfer, other than restrictions on transfer under this
Agreement, the Investors' Rights Agreement, the Stockholders' Agreement and
under applicable state and federal securities laws. The Common Stock issuable
upon conversion of the Series C Preferred Stock purchased under this Agreement
has been duly and validly reserved for issuance and, upon issuance in accordance
with the terms of the Restated Certificate, will be duly and validly issued,
fully paid and nonassessable, free and clear of all liens and other encumbrances
and will be free of restrictions on transfer, other than restrictions on
transfer under this Agreement, the Investors' Rights Agreement, the
Stockholders' Agreement and under applicable state and federal securities laws.

               2.6  Consents. No consent, approval, order or authorization of,
                    --------
or registration, qualification, designation, declaration or filing with, any
federal, state or local governmental authority or any individual, firm,
corporation, partnership, trust, limited liability company, incorporated or
unincorporated association, joint venture, joint stock company or other entity
of any kind (each, a "Person") on the part of the Company is required in
connection with the consummation of the transactions contemplated by this
Agreement, except for filings required pursuant to applicable federal and state
securities laws and blue sky laws, which filings will be effected within the

Statement with the Securities and Exchange Commission on February 18, 2000 and
an S-1/A Registration Statement on March 28, 2000 (File No. 333-30684) for the

"qualified institutional buyer" within the meaning of Rule 144A of the
Securities Act of 1933, as amended (the "Act") or an institutional "accredited
investor" as defined under Regulation D of the Act as set forth in Section 3.10,
the offer, sale and issuance of the Series C Preferred Stock as contemplated by
this Agreement are exempt from the registration requirements of the Act.

               2.8  Litigation. There is no action, suit, proceeding or
                    ----------
investigation pending, or to the Company's knowledge currently threatened,
against the Company that questions the validity of this Agreement, the
Investors' Rights Agreement or the Stockholders' Agreement or the right of the
Company to enter into any of the foregoing or to consummate the transactions
contemplated hereby or thereby, or that would have, either individually or in
the aggregate, an MAE. The Company is not a party or subject to the provisions
of any order, writ, injunction, judgment or decree of any court or government
agency or instrumentality. There is no action, suit, proceeding or investigation
by the Company currently pending or that the Company intends to initiate.

               2.9  Proprietary Information Agreements. Each employee and
                    ----------------------------------
officer of the Company has executed a Proprietary Information and Inventions
Agreement in substantially the form provided to the Investors.

               2.10 Patents and Trademarks. Schedule 2.10 sets forth a complete
                    ----------------------  -------------
and accurate list and description of all material franchises, licenses, patents,
patent rights, patent applications, trademarks, trademark rights, service marks,
service mark rights, trade names, trade name rights, copyrights and rights with
respect to any of the foregoing (collectively, "Intellectual Property")
presently owned or held by the Company. The Company owns the right to use all of
the Intellectual Property. To the actual knowledge of the Company (without
independent investigation), the Intellectual Property is all that is necessary
for the Company to conduct its business as presently conducted. To its knowledge
(but without having conducted any special investigation or patent search), no
Intellectual Property conflicts with or infringes on the valid rights of others
and the Company has not received any notice of infringement upon or conflict
with the asserted rights of others. No event has occurred which permits, or
after notice or lapse of time would permit, the revocation or termination of any
of the Intellectual Property. The Company has a valuable body of trade secrets,
including know-how, concepts, computer programs and other technical data (the
"Proprietary Information"). To its knowledge, the Company has the right to use
the Proprietary Information free and clear of any rights, liens, encumbrances or
claims of others, except that the possibility exists that other persons may have
independently developed trade secrets or technical information similar or
identical to those of the Company. The Company is not aware of any such
independent development nor of any misappropriation of its Proprietary
Information. The Company is not aware that any of its employees is obligated
under any contract (including licenses, covenants or commitments of any nature)
or other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of his or her best
efforts to promote the interests of the Company or that would conflict with the
Company's business. The Company

                                       5
<PAGE>

does not believe it is or will be necessary to utilize any inventions of any of
its employees (or people it currently intends to hire) made prior to their
employment by the Company, except for inventions that have been assigned or
licensed to the Company as of the date hereof.

               2.11 Compliance with Other Instruments. The Company is not in
                    ---------------------------------
violation of any provision of its Restated Certificate or Bylaws or any
securities issued by the Company, any indenture, credit agreement, contract,
agreement, instrument or other undertaking ("Contractual Obligations") or any
judgment, order, writ, decree or contract, statute, rule or regulation to which
the Company or its assets or property is subject ("Requirements of Law"), a
violation of which would have an MAE. The execution, delivery and performance of
this Agreement, the Investors' Rights Agreement and the Stockholders' Agreement
and the consummation of the transactions contemplated hereby and thereby will
not result in any such violation, or be in conflict with or constitute, with or
without the passage of time and giving of notice, either a default under any
Contractual Obligation or Requirement of Law or an event that results in the
creation of any lien, charge or encumbrance upon any assets of the Company or
the suspension, revocation, impairment, forfeiture or nonrenewal of any material
permit, license, authorization or approval applicable to the Company, its
business or operations or any of its assets or properties.

               2.12 Agreements; Action.
                    ------------------

                    (a)  Except for agreements explicitly contemplated hereby,
there are no agreements, understandings or proposed transactions between the
Company and any of its officers, directors, affiliates or any affiliate thereof.

                    (b)  Except for this Agreement, the Investors' Rights
Agreement and the Stockholders' Agreement, Schedule 2.12 hereto sets forth a
                                           -------------
complete and accurate list of all material Contractual Obligations of the
Company in effect on and as of the Closing. To its knowledge, each such
Contractual Obligation is valid and enforceable by the Company against any other
party thereto in accordance with its terms except to the extent that such
enforcement may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium and other laws of general application affecting enforcement of
creditors' rights generally, and by laws relating to the availability of
specific performance, injunctive relief or other equitable remedies. The Company
has performed and is in compliance with all of the terms of such Contractual
Obligations and all instruments and agreements relating thereto and no default
or event of default, or event or condition which with notice or lapse of time or
both would constitute such a default or event of default, on its part or on the
part of any other party thereto exists with respect to any material Contractual
Obligation of the Company, except where such nonperformance, noncompliance,
default or event of default is not reasonably likely to result in an MAE. The
Company has no actual knowledge that any such Contractual Obligation contains
any contractual requirement with which there is a reasonable likelihood the
Company will be unable to comply and such failure to comply would likely result
in an MAE or the Company's compliance is reasonably likely to result in an MAE.

                    (c)  There are no judgments, orders, writs or decrees to
which the Company is a party or by which it is bound that involve obligations
(contingent or otherwise) of, or payments to the Company, in excess of $25,000.

                                       6
<PAGE>

                    (d)  The Company has not (i) declared or paid any dividends
or authorized or made any distribution upon or with respect to any class or
series of its capital stock, (ii) except for the anticipated credit facility
currently being negotiated, incurred any indebtedness for money borrowed or any
other liabilities individually in excess of $100,000 or, in the case of
indebtedness and/or liabilities individually less than $100,000, in excess of
$250,000 in the aggregate, (iii) made any loans or advances to any Person, other
than advances in the ordinary course of business, or (iv) sold, exchanged or
otherwise disposed of any of its assets or rights, other than the sale of its
inventory in the ordinary course of business.

                    (e)  For the purposes of subsections (c) and (d) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same Person (including Persons the
Company has reason to believe are affiliated therewith) shall be aggregated for
the purpose of meeting the individual minimum dollar amounts of such
subsections.

               2.13 Related-Party Transactions. No employee, officer or director
                    --------------------------
of the Company or member of his or her immediate family is indebted to the
Company, nor is the Company indebted (or committed to make loans or extend or
guarantee credit) to any of them. To the best of the Company's knowledge, none
of such persons has any direct or indirect ownership interest in any firm or
corporation with which the Company is affiliated or with which the Company has a
business relationship, or any firm or corporation that competes with the
Company, except that employees, officers or directors of the Company and members
of their immediate families may own stock in publicly traded companies that may
compete with the Company. No member of the immediate family of any officer or
director of the Company is directly or indirectly interested in any material
Contractual Obligation with the Company.

               2.14 Financial Statements. The Company has delivered to each
Investor its audited financial statements (balance sheet and statement of
operations, statement of stockholders' equity and statement of cash flows,
including notes thereto) at December 31, 1999 and for the fiscal year then ended
and its unaudited financial statements (balance sheet and statement of
operations, statement of stockholders' equity and statement of cash flows) at
March 31, 2000 and for the three-month period then ended (the "Financial
Statements"). The Financial Statements have been prepared in all material
respects in accordance with generally accepted accounting principles applied on
a consistent basis throughout the periods indicated and with each other and
fairly present in all material respects the assets, liabilities, financial
condition and operating results of the Company as of the dates, and for the
periods, indicated therein, subject in the case of unaudited Financial
Statements to normal year-end audit adjustments. Except as set forth in the
Financial Statements, the Company has no liabilities or obligations, contingent
or otherwise, other than (i) liabilities incurred in the ordinary course of
business subsequent to March 31, 2000 and (ii) obligations under contracts and
commitments incurred in the ordinary course of business and not required under
generally accepted accounting principles to be reflected in the Financial
Statements, which, in both cases, individually or in the aggregate, are not
material to the financial condition or operating results of the Company and
which the Company has satisfied as they have become due. Except as disclosed in
the Financial Statements, the Company is not a guarantor or indemnitor of any
indebtedness of any other Person. The Company maintains and will continue to
maintain a standard system of accounting established and administered in
accordance with generally accepted accounting principles.

consistent with past practice that are not reasonably likely to have an MAE;

               3.1  Authorization. Such Investor has full power and authority to
                    -------------
enter into this Agreement, the Investors' Rights Agreement and the Stockholders'
Agreement, and each such agreement constitutes its valid and legally binding
obligation, enforceable in accordance with its terms, except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium and other laws of
general application affecting enforcement of creditors' rights generally, (ii)
as limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies, and (iii) to the extent the
indemnification provisions contained in the Investors' Rights Agreement may be
limited by applicable federal or state securities laws.

               3.2  Purchase Entirely for Own Account. This Agreement is made
                    ---------------------------------
with such Investor in reliance upon such Investor's representation to the
Company, which by such Investor's execution of this Agreement such Investor
hereby confirms, that the Series C Preferred Stock to be received by such
Investor and the Common Stock issuable upon conversion thereof (collectively,
the "Securities") will be acquired for investment for such Investor's own
account and not with a view to the resale or distribution of any part thereof in
violation of applicable securities laws, and that such Investor has no present
intention of selling, granting any participation in or otherwise distributing
the same in violation of applicable securities laws. By executing this
Agreement, such Investor further represents that such Investor does not have any
contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person in
violation of applicable securities laws, with respect to any of the Securities.

               3.3  Disclosure of Information. Such Investor believes it has
                    -------------------------
received all the information it considers necessary or appropriate for deciding

               3.4  Investment Experience. Such Investor is an investor in
                    ---------------------
securities of companies in the development stage and acknowledges that it can
bear the economic risk of its investment, and has such knowledge and experience
in financial or business matters that it is capable of evaluating the merits and
risks of the investment in the Series C Preferred Stock. If other than an
individual, such Investor also represents it has not been organized for the
purpose of acquiring the Series C Preferred Stock.

               3.5  Restricted Securities. Such Investor understands that the
                    ---------------------
Securities it is purchasing are characterized as "restricted securities" under
the federal securities laws inasmuch as they are being acquired from the Company
in a transaction not involving a public offering and that under such laws and
applicable regulations such Securities may be resold without registration under
the Act only in certain limited circumstances. In the absence of an effective
registration statement covering the Series C Preferred Stock (or the Common
Stock issued on conversion thereof) or an available exemption from registration
under the Act, the Series C Preferred Stock (and any Common Stock issued on
conversion thereof) must be held indefinitely. In this connection, such Investor
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Act, including
without limitation the Rule 144 condition that current information about the
Company be available to the public. Such information is not now available and
the Company has no present plans to make such information available.

to make any disposition of all or any portion of the Securities unless:

                    (a)  There is then in effect a registration statement under
the Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

                    (b)  (i)  Such Investor shall have notified the Company of
the proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
requested by the Company, such Investor shall have furnished the Company with an
opinion of counsel, reasonably satisfactory to the Company that such disposition
will not require registration of such shares under the Act. It is agreed that
the Company will not require opinions of counsel for transactions made pursuant
to Rule 144 except in unusual circumstances.

                    (c)  Notwithstanding the provisions of subsections (a) and
(b) above, no such registration statement or opinion of counsel shall be
necessary for a transfer by an Investor that is a partnership to a partner of
such partnership or a retired partner of such partnership who retires after the
date hereof, or to the estate of any such partner or retired partner or the
transfer by gift, will or intestate succession of any partner to his or her
spouse or to the siblings, lineal descendants or ancestors of such partner or
his or her spouse, if the transferee agrees in writing to be subject to the
terms hereof to the same extent as if he or she were an original Investor
hereunder.

Securities Act of 1933, as amended. They may not be sold, offered for sale,
pledged or hypothecated in the absence of a registration statement in effect
with respect to the securities under such Act or an applicable exemption
therefrom."

                    (b)  Any legend required by the Investors' Rights Agreement
and the Stockholders' Agreement.

The Company agrees, upon the request of any Investor or its transferee, to
remove the legend required by paragraph (a) above at such time as all Securities
held by such person may be freely transferred pursuant to SEC Rule 144(k), and
to remove the legend required by paragraph (b) above at such time as the
restrictions of the Investors' Rights Agreement and the Stockholders' Agreement
are no longer applicable to such Securities.

               3.8  Tax Advisors. Such Investor has reviewed with such
                    ------------
