and Cornerstone Equity Investors IV, LP, Private Equity Portfolio Fund II, LLC,

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

               1.1  Omitted.
                    -------

               1.2  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 Fifth 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
of Cornerstone Equity Investors IV, LP, Private Equity Portfolio Fund II, LLC,
BMO Nesbitt Burns Capital (U.S.), Inc., Carlyle High Yield Partners, L.P., Spire
Capital Partners, L.P. and Stolberg, Meehan and Scano II, L.P. agrees, severally
but not jointly, to purchase from the Company at the Closing, and the Company
agrees to sell and issue to each Additional Investor at the Closing, that number
of shares of Series C Preferred Stock set forth opposite such Additional
Investor's name on Schedule A hereto (the "Purchase Shares") for a purchase
                   ----------
price of $20.50 per share.

               1.3  Closing.  The purchase and sale of the Series C Preferred
                    -------
Stock to the Additional Investors shall take place at the Company's offices
located at 938 Bannock Street, Suite 300, Denver, Colorado 80204 at 10:00 a.m.
on August 11, 2000, or at such other time and place as the Company and the
Additional Investors mutually agree upon orally or in writing (which time and
place are designated as the "Closing").  No later than August 31, 2000, the
Company shall deliver to each Additional Investor a certificate representing the
Series C Preferred Stock that such Additional Investor is purchasing against
payment of the purchase price therefor by wire transfer of immediately available
funds.

               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 Additional
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 Additional Investors, an additional
number of shares of Series C Preferred Stock such that each Additional 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
<PAGE>

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 (i) be treated as if they were issued
at the Closing, (ii) shall reflect any anti-dilution adjustments arising from
the date of Closing through the date of such issuance, and (iii) be deemed to be
an adjustment to the per share purchase price of the Series C Preferred Stock
set forth in Section 1.2(b) above and to have been issued as part of a single
integrated transaction with the issuance of the shares of Series C Preferred
Stock at the Closing. 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.

               1.5  Omitted.
                    -------

               1.6  Restated Certificate Adjustments.  The parties agree for
                    --------------------------------
federal tax purposes to treat any adjustments to the Conversion Price (as
defined in the Restated Certificate) of the Series C Preferred Stock as a result
of a Reduced Offering (as defined in the Restated Certificate) or a Reduced
Liquidation Event (as defined in the Restated Certificate) as adjustments to the
purchase price of the Purchase Shares.

          2.  Representations and Warranties of the Company.  The Company
              ---------------------------------------------
hereby represents, warrants and covenants to each Additional Investor with
respect to the purchase of the Purchase Shares on the date hereof that, except
as set forth on the Schedule of Exceptions (the "Schedule of Exceptions")

                   ----------

under the laws of the State of Delaware. The Company has all requisite corporate

Investors' Rights Agreement and the Stockholders' Agreement, and to issue, sell
and deliver the Purchase Shares and the Common Stock (as hereinafter defined)
issuable upon conversion of the Purchase Shares. The Company is duly qualified
to transact business and is in good standing in each jurisdiction in which the

assets, operations, properties or financial condition of the Company (an "MAE").

                    --------------------------------

     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

                                       2
<PAGE>

     (iii) 7,610,000 shares have been designated Series C Preferred Stock (the
     "Series C Preferred Stock"), of which 5,707,317 shares are outstanding. The
     rights, privileges and preferences of the Series A Preferred Stock, Series
     B Preferred Stock, and Series C Preferred Stock are as stated in the
     Restated Certificate.

                         (ii) Common Stock.  42,080,000 shares of common stock,
                              ------------
     par value $0.001 ("Common Stock"), of which 3,655,480 shares are issued and
     outstanding.

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

                    (c) The outstanding shares of Series A Preferred Stock,
Series B Preferred Stock, Series C 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
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock, (B) the
rights provided in Section 3 of the Fifth Amended and Restated Stockholders'
Agreement in the form attached hereto as Exhibit C (the "Stockholders'
                                         ---------
Agreement"), and (C) 1,798,000 options outstanding as of June 15, 2000, as set
forth on Schedule 2.2 (which list is true and complete in all material
         ------------
respects), 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/Stock Issuance Plan, as amended (the
"Option Plan"), which Option Plan authorizes the grant of options to purchase up
to 2,685,000 shares of Common Stock ("Management Option Pool"), 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. All options granted from the Management Option Pool
shall contain vesting and buy-back restrictions in substantially the same form
as issuances of options from the Management Option Pool prior to the date of
this Agreement. The Company may also 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 5,707,317 outstanding shares of Series C Preferred
Stock combined with the issuance by the Company of 1,902,440 shares of Series C
Preferred Stock pursuant to the terms of this Agreement, as of the date hereof
would constitute, in the aggregate, approximately 31% 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, except for the subsidiaries listed on
Exhibit D attached hereto. The Company is not a participant
---------

                                       3
<PAGE>

in any joint venture, partnership, or similar arrangement. The Company is not,
directly or indirectly, subject to any obligation or requirement to provide
funds to, or invest in any company, partnership, association, joint venture or
similar non-corporate business enterprise.

               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 Fifth Amended and
Restated Investors' Rights Agreement in the form attached hereto as Exhibit E
                                                                    ---------
(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
                    --------------------------------------------
Preferred Stock that is being purchased hereunder, when issued, sold and
delivered in accordance with the terms of this Agreement for the 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 being purchased hereunder 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 which have not been obtained prior to the date of this Agreement,
except for filings required pursuant to applicable federal and state securities
laws and blue sky laws.

               2.7  Offering.  The Company filed a Registration Statement on
                    --------
Form S-1 with the Securities and Exchange Commission on February 18, 2000 and
filed amendments thereto on March 28, 2000 and May 12, 2000 (File No. 333-30684)
for the issuance of up to 8,050,000 shares of its Common Stock. Assuming the
truth and accuracy of each Additional Investor's representations set forth in
Section 3 of this Agreement (and such similar representations made by other
purchasers of the Company's Series C Preferred Stock), including without
limitation the qualification of each Additional Investor as a "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 and the issuance of the Common Stock upon conversion of such Series C
Preferred Stock as contemplated by the Restated Certificate 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 made available to the Additional 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, trademark
applications, service marks, service mark rights, trade names, trade name
rights, copyrights, copyright applications, 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 or as it is presently proposed to be 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,
technology, streaming media files, domain name, domain name applications,
databases, websites, other materials included on the Company's website 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

                                       5
<PAGE>

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 or infringement of its Proprietary Information or Intellectual
Property.  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 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) or consultants 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.  The Company has taken reasonable steps to protect and preserve the
security and confidentiality of its Intellectual Property and Proprietary
Information.  Immediately following the Closing, the Company will continue to
own or license all Intellectual Property and Proprietary Information owned or
use by it on the same terms and conditions as immediately prior to the Closing.

               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 (i) a default under the
Restated Certificate, the Bylaws, any Contractual Obligation or Requirement of
Law, or (ii) 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

                                       6
<PAGE>

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, to its actual
knowledge, 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.

                     (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 a potential credit facility the
Company is considering entering into, as set forth on the Financial Statements
(as hereinafter defined), or pursuant to the Contractual Obligations set forth
on Schedule 2.12, incurred any indebtedness for money borrowed or any other
   -------------
liabilities which would be commitments required to be disclosed in the footnotes
to financial statements under generally accepted accounting principles,
individually for which it currently owes, or in the future will owe 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, holder of greater than five percent (5%) of the
Company's outstanding Common Stock, or member of his or her immediate family is
indebted to, or a party to any agreements, contracts or transactions with 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
                     --------------------
Additional Investor its audited financial statements (balance sheet and
statement of operations,

                                       7
<PAGE>

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 accordance with the books and records
of the Company, have been prepared 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.

               2.15  Changes. Since March 31, 2000, except for the prior
                     -------
issuances of shares of Series C Preferred Stock, there has not been:

                     (a) any change in the assets, liabilities, financial
condition or operating results of the Company from that reflected in the
Financial Statements, except changes in the ordinary course of business
consistent with past practice that are not reasonably likely to have an MAE;

                     (b) any damage, destruction or loss, whether or not covered
by insurance, materially and adversely affecting the assets, properties,
financial condition, operating results or business of the Company;

                     -------------
authority to enter into this Agreement, the Investors' Rights Agreement and the

<PAGE>

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 each Additional Investor in reliance upon such Additional Investor's
representation to the Company, which by such Additional Investor's execution of
this Agreement such Additional Investor hereby confirms, that the Series C
Preferred Stock to be received by such Additional Investor and the Common Stock
issuable upon conversion thereof (collectively, the "Securities") will be
acquired for investment for such Additional 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 Additional 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 Additional Investor further represents that such Additional
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 Additional Investor
                    -------------------------

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

organized for the purpose of acquiring the Series C Preferred Stock.

               3.5  Restricted Securities. Such Additional 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 Additional 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.

<PAGE>

                    (a)   Without in any way limiting the representations set

of all or any portion of the Securities unless:

                         (i)  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

                         (ii) (A)  Such Additional Investor shall have notified
the Company of the proposed disposition and shall have furnished the Company, if
reasonably requested, with a detailed statement of the circumstances surrounding
the proposed disposition, and (B) if reasonably requested by the Company, such
Additional 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.

                    (b)  Notwithstanding the provisions of subsections (i) and
(ii) above, no such registration statement or opinion of counsel shall be
necessary for a transfer by an Additional Investor to any affiliate or limited
or general partner of such Additional Investor 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 Additional Investor hereunder.

the Securities may bear one or all of the following legends:

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 Additional 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) or are properly sold pursuant to an effective registration
statement under the Act, 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 Additional Investor has reviewed with

accordance with the notice requirements of this Agreement prior to or

          (d) If the Company does not elect to purchase all of the Offered
Shares from the RFR Holder, each Purchaser Holder shall have the absolute right
at any time within ten (10) days following the expiration of the Company
Election Period (the "Purchaser Election Period") to elect to purchase, at the
price per share specified in the Sale Notice, or if no price is specified
therein, at the Fair Market Value thereof, that portion of the balance of the
Offered Shares from the RFR Holder as shall be equal to the number of such
Offered Shares multiplied by a fraction, the numerator of which shall be the
number of Preferred Shares then owned by each Purchaser Holder and the
denominator of which shall be the aggregate number of Preferred Shares then
owned by all of the Purchaser Holders.  (The amount of Offered Shares that each
Purchaser Holder is entitled to purchase under this Section 2(e) shall be
referred to as its "Pro Rata Share").

          (e) If any Purchaser Holder elects not to exercise its option to
purchase its Pro Rata Share of the Offered Shares from the RFR Holder, then
those Purchaser Holders that do exercise their option shall have the option, for
an additional five (5) days following the end of the Purchaser Election Period,
to elect to acquire the Offered Shares that could have been acquired by the
nonexercising Purchaser Holders in proportion to the relative number of
Preferred Shares held by the exercising Purchaser Holders.

          (f) If the Company and/or the Purchaser Holders elect to purchase all
or any portion of the Offered Shares from the RFR Holder, any written
communication of an election to so purchase delivered by the Company or the
Purchaser Holders shall, when taken in conjunction with the offer, be deemed to
constitute a valid, legally binding and enforceable agreement for the sale and
purchase of the stated Offered Shares.  Sales of the Offered Shares to be sold
to the Company and/or the Purchaser Holders pursuant to this Section 2 shall be
made at

                                       3
<PAGE>

the offices of the Company on the 60th day following the date of the Sale Notice
(or if such 60th day is not a business day, then on the next succeeding business
day). Such sales shall be effected by the delivery to the Company of a
certificate or certificates evidencing the Offered Shares to be purchased by the
Company or the Purchaser Holders duly endorsed for transfer to such party, free
and clear of all liens, claims and encumbrances except those arising under this
Agreement and the Investors' Rights Agreement of even date herewith, against
payment to the RFR Holder of the purchase price therefor by the party purchasing
such Offered Shares.

          (g) If the Company and/or the Purchaser Holders do not purchase all of
the Offered Shares from the RFR Holder, then, subject to the other terms of this
Agreement all, but not less than all, of the Offered Shares not so purchased may
be sold by the RFR Holder at any time within ninety (90) days after the date of
the Sale Notice. Any such sale shall be to the proposed transferee specified in
the Sale Notice, at not less than the price and upon other terms and conditions,
if any, not more favorable to the proposed transferee than those specified in
the offer. If the Offered Shares are not sold within such 90-day period, the RFR
Holder shall not thereafter transfer any Offered Shares without again complying
with the requirements of this Section 2.

          (h) In the event that the Selling Stockholder is a Purchaser Holder,
the Company shall have the right to approve the proposed transferee(s) of the
Offered Shares, which approval shall not be unreasonably withheld (it being
understood that the Company's failure to approve a proposed transferee that the
Company believes in good faith constitutes an actual or potential competitor of
the Company shall be conclusively deemed reasonable).

          (i) If Offered Shares are sold pursuant to this Section 2 to any
purchaser who is not a party to this Agreement, it shall be a condition of such
sale that the purchaser shall execute a counterpart of this Agreement and the
Offered Shares so sold shall be subject to this Agreement.

      3.  Preemptive Right.
          ----------------

          (a) The Right.  If the Company shall propose to issue any New
              ---------
Securities, it shall first offer to sell to each Purchaser Holder a Ratable
Portion of such New Securities on the same terms and conditions and at the
lowest price as such New Securities are offered to any person.  "Ratable
Portion" shall mean that portion of such New Securities equal to the fraction
determined by dividing the number of shares of Common Stock held by the
Purchaser Holder (assuming full conversion and exercise of all convertible or
exercisable securities held by such Purchaser Holder) by the number of Common
Shares then outstanding (assuming full conversion and exercise of all
convertible or exercisable securities but excluding the New Securities so
issued).

          (b) Notice.  The Company shall give written notice of the proposed
              -------
issuance of New Securities to each Purchaser Holder not later than thirty (30)
days prior to issuance.  Such notice shall contain all material terms and
conditions of the issuance and of the New Securities.  Each Purchaser Holder may
elect to exercise all or any portion of its rights under this Section 3 by
giving written notice to the Company within thirty (30) days of the

                                       4
<PAGE>

Company's notice. If the consideration paid by others for the New Securities is
not cash, the value of the consideration shall be determined in good faith by
the Company's Board of Directors (with no less than 2/3 of the group consisting
of the Series C Director and the Outside Directors (as defined in Section 7
below) voting to approve the value so determined), and any electing Purchaser
Holder shall pay the cash equivalent thereof as so determined. All payments
shall be delivered by electing Purchaser Holders to the Company not later than
the date specified by the Company in its notice, but in no event earlier than
thirty-five (35) days after the Company's notice. Each Purchaser Holder shall
have a right of over allotment such that, if any other Purchaser Holder fails to
exercise the right to purchase its full Ratable Portion of the New Securities,
the other participating Purchaser Holders may, before the date ten (10) days
following the expiration of the thirty (30) day period, set forth above,
exercise an additional right to purchase, on a pro rata basis, the New
Securities not previously purchased by so notifying the Company, in writing,
within such ten (10) day period. Each Purchaser Holder shall be entitled to
apportion New Securities to be purchased among its affiliates, members and
general and limited partners, provided that such Purchaser Holder notifies the
Company of such allocation.

          4.  Right of Co-Sale.
              ----------------

              (a) The Right.  If at any time a Selling Stockholder proposes to
                  ---------
sell any shares of Stock to any third party in a transaction involving the sale
of more than five percent (5%) of the then-outstanding Common Stock determined
on an as-converted basis (a "Co-Sale Transaction"), then the Sale Notice
required by Section 2 shall be delivered to all Stockholders. For purposes of
calculating the preceding percentage, all transfers by a Selling Stockholder
shall be aggregated with all prior and contemporaneous transfers by such Selling
Stockholder (not including transfers to affiliates, members and general and
limited partners). In the event that, after giving effect to all purchases of
such Stock by the Company and the Purchaser Holders pursuant to Section 2, the
amount of Stock to be sold to such third party continues to represent at least
five percent (5%) of the then-outstanding Common Stock on an as-converted basis,
then each Stockholder which notifies the Selling Stockholder in writing within
30 days following receipt of the Sale Notice (a "Co-Seller") shall have the
opportunity to sell a pro rata portion of the remaining Stock which the Selling
Stockholder proposes to sell to such third party in the Co-Sale Transaction. In
the event a Co-Seller exercises its right of co-sale hereunder, the Selling
Stockholder shall assign so much of his interest in the proposed agreement of
sale as the Co-Seller shall be entitled to and shall request hereunder, and the
Co-Seller shall assume such part of the obligations of the Selling Stockholder
under such agreement as shall relate to the sale of the securities by the Co-
Seller. For the purposes of this Section 4, the "pro rata portion" which each
Co-Seller shall be entitled to sell shall be an amount of Stock equal to a
fraction of the total amount of Stock proposed to be sold to such third party
(after giving effect to all purchases pursuant to Section 2), the numerator of
which shall be the number of shares of Stock owned by such Co-Seller and the
denominator of which shall be the total number of shares of Stock then held by
the Selling Stockholder and all Co-Sellers (giving effect in each case to the
conversion of all Preferred Shares into Common Stock). Insofar as possible this
right of co-sale shall apply to Stock of the same class or classes as the Stock
subject to the Sale Notice. If any Person desiring to exercise its rights of co-
sale hereunder does not have a sufficient amount of Stock of the same class as
the Stock subject to the Sale Notice, such Person may substitute Stock of
another class so long as such class ranks senior in liquidation to the class of
Stock subject to

                                       5
<PAGE>

the Sale Notice. In the event the proposed Transfer is of Common Stock and a
Person wishing to exercise its rights of co-sale hereunder does not have
sufficient shares of Common Stock, but has Preferred Shares, such Person may
convert a sufficient number of Preferred Shares into Common Stock in accordance
with the procedures set forth in the Certificate of Incorporation, as amended.

          (b) Failure to Notify. If within thirty (30) days following receipt of
              -----------------
the Sale Notice, any Stockholder fails to notify the Selling Stockholder that it
desires to participate in the Co-Sale Transaction, then the Selling Stockholder
may effect the Co-Sale Transaction within a period of ninety (90) days after the
date of the Sale Notice without the participation of such Stockholder. Any such
sale shall be made only to persons identified in the Sale Notice and at the same
price and upon the same terms and conditions as those set forth in the Sale
Notice. In the event the Selling Stockholder has not sold the Stock or entered
into an agreement to sell the Stock within such ninety (90) day period, the
Selling Stockholder shall not thereafter sell any Equity Securities without
again complying with Section 2 and this Section 4.

          (c) Prohibited Transfers. In the event that a Selling Stockholder
              --------------------
should sell any Stock in contravention of the co-sale rights under this
Agreement (a "Prohibited Transfer"), each holder of such co-sale rights, in
addition to such other remedies as may be available at law, in equity or
hereunder, shall have the put option provided below, and such Selling
Stockholder shall be bound by the applicable provisions of such option. In the
event of a Prohibited Transfer, each holder of co-sale rights shall have the
right to sell to such Selling Stockholder the type and number of shares of Stock
equal to the number of shares each holder of co-sale rights would have been
entitled to transfer to the purchaser under Section 4(a) hereof had the
Prohibited Transfer been effected pursuant to and in compliance with the terms
hereof. Such sale shall be made on the following terms and conditions:

              (i)   The price per share at which the shares are to be sold to
         the Selling Stockholder shall be equal to the price per share paid by
         the purchaser to such Selling Stockholder in such Prohibited Transfer.
         The Selling Stockholder shall also reimburse each co-sale rights holder
         for any and all fees and expenses, including legal fees and expenses,
         incurred pursuant to the exercise or the attempted exercise of the
         rights under Section 4.

              (ii)  Within ninety (90) days after the date on which a holder of
         co-sale rights received notice of the Prohibited Transfer or otherwise
         became aware of the Prohibited Transfer, such Person shall, if
         exercising the option created hereby, deliver to the Selling
         Stockholder the certificate or certificates representing shares to be
         sold, each certificate to be properly endorsed for transfer, free and
         clear of all liens, claims and encumbrances except those arising under
         this Agreement and the Investors' Rights Agreement of even date
         herewith.

              (iii) Such Selling Stockholder shall, upon receipt of the
         certificate or certificate for the shares to be sold by a co-sale
         rights holder pursuant to this Section 4(c), pay the aggregate purchase
         price therefor and

                                       6
<PAGE>

               the amount of reimbursable fees and expenses, as specified in
               Section 4(c)(i), in cash or by other means acceptable to the co-
               sale rights holder.

           5.  Limitations to Rights of First Refusal and Co-Sale.
               --------------------------------------------------
Notwithstanding the provisions of Sections 2 and 4 of this Agreement, each
Purchaser Holder may sell or otherwise assign, with or without consideration, an
unlimited amount of Stock to any spouse or member of his immediate family, or to
a custodian, trustee (including a trustee of a voting trust), executor or other
fiduciary for the account of his spouse or members of his immediate family, or
to a trust for himself, or to a charitable remainder trust, or any affiliate,
member or limited or general partner of such Purchaser Holder; provided that
each such transferee or assignee, prior to the completion of the sale, transfer
or assignment shall have executed documents assuming the obligations of the
Purchaser Holder under this Agreement with respect to the transferred
securities. Notwithstanding the provisions of Section 4 of this Agreement, each
of Art Zeile and Joel Daly may sell his Common Shares without the participation
of any Co-Seller following the termination of his employment with the Company
(not including such individual's voluntary termination of his employment with
the Company), other than for Cause, or following a material reduction in his (i)
duties and responsibilities or (ii) compensation, unless agreed to by such
Common Holder or required by law, or a material change in his responsibilities
which are not agreed to by such Common Holder. As used herein, "Cause" shall
mean a termination for any of the following reasons: (i) engaging in intentional
misconduct which would tend to discredit the Company; (ii) being convicted of a
felony; (iii) committing an act of fraud against the Company or the willful
material misappropriation of property belonging to the Company; (iv) materially
breaching any proprietary information agreement between such Common Holder and
the Company or (v) willfully disregarding such Common Holder's duties despite
adequate warnings from the Board.

         6.  Drag-Along Rights. If holders of (i) greater than 50% of the
             -----------------
outstanding Series A and Series B Preferred Stock (voting together as a single
class) and (ii) greater than 50% of the outstanding Series C Preferred Stock
(together, the "Required Preferred Holders") approve any liquidation,
dissolution or winding up of the Company or a transaction to sell, or in any
other way, directly or indirectly convey, assign, distribute, pledge, encumber
or otherwise dispose of all or substantially all of the Company's assets,
property or business or merge into or consolidate with any other corporation
(other than a wholly-owned subsidiary of the Company) or effect any transaction
or series of related transactions in which more than fifty percent (50%) of the
voting power of the Company is disposed of (collectively, a "Drag-Along
Transaction"), then, upon thirty (30) days written notice to the other
Stockholders and the Company (the "Drag-Along Notice"), which notice shall
include reasonable details of the proposed transaction, including the proposed
time and place of closing and the consideration to be received by the
Stockholders in such transaction, each Stockholder shall raise no objection to
such Drag-Along Transaction and be obligated to, and shall sell, transfer and
deliver, or cause to be sold, transferred and delivered, to such third party,
all of his Equity Securities in the same transaction at the closing thereof (and
will deliver certificates for all of his shares at the closing, free and clear
of all liens, claims, or encumbrances except those arising under this Agreement
and the Investors' Rights Agreement of even date herewith). Each Common Holder
shall receive the same consideration per share on an as-converted to Common
Stock basis upon consummation of the Drag-Along Transaction as is received by
the holders of Preferred Shares after giving effect

                                       7
<PAGE>

to any liquidation preference to which any Person is entitled to pursuant to the
Company's Certificate of Incorporation, as amended; provided, however, that if
within thirty (30) days of receipt of the Drag-Along Notice, the Company
irrevocably commits in writing to use its best efforts to complete a firm
commitment underwritten public offering pursuant to an effective registration
statement under the Securities Act covering the offer and sale of the Company's
Common Stock at a price per share of not less than the price per share which the
holders of the Equity Securities (on an as-converted to Common Stock basis)
would receive upon the consummation of the Drag-Along Transaction (a "Qualified
IPO"), then the closing of the Drag-Along Transaction shall be suspended until
the earlier of (i) one hundred twenty (120) days after the Company so commits or
(ii) the date the Company determines that it will be unable to complete the
Qualified IPO within such 120-day period.

         7.   Board of Directors.
              ------------------

              (a) Composition.  The Stockholders agree that, in any election of
                  -----------
directors of the Company (or action by written consent in lieu thereof), they
shall vote all shares of capital stock of the Company owned or controlled by
them (or act by written consent) to elect a Board of Directors comprised of
seven members designated as follows:

                  (i)   two directors (the "Common Directors"), each of
               whom shall be an executive officer of the Company designated by
               the holders of a majority of the then-outstanding Common Stock
               (currently Art Zeile and Joel Daly);

                  (ii)  one director (the "Series A Director"), which
               shall be designated by First Union Capital Partners, Inc.
               (currently Scott Perper) so long as such Stockholder and its
               affiliates continue to hold at least 1,122,143 shares of Series A
               Preferred Stock, as adjusted; provided, however, at such time
               that First Union Capital Partners, Inc. does not hold at least
               1,122,143 shares of Series A Preferred Stock, as adjusted, the
               holders of a majority of the then outstanding Series A Preferred
               Stock, voting as a separate class, shall designate the Series A
               Director;

                  (iii) one director (the "Series B Director"), which shall be
               designated by Meritage Private Equity Fund, L.P. (currently G.
               Jackson Tankersley, Jr.) so long as such Stockholder and its
               affiliates continue to hold at least 1,149,851 shares of Series B
               Preferred Stock, as adjusted; provided, however, at such time
               that Meritage Private Equity Fund, L.P. does not hold at least
               1,149,851 shares of Series B Preferred Stock, as adjusted, the
               holders of a majority of the then outstanding of Series B
               Preferred Stock, voting as a separate class, shall designate the

                  (iv)  two independent directors (the "Outside Directors")
               selected by the holders of a majority of the then-outstanding
               Common Stock and approved by the holders of a majority of the
               then-outstanding

                                       8
<PAGE>

               Preferred Shares (currently Stephen O. James and Donald F.
               Detampel, Jr.); and

                    (v) one director (the "Series C Director") which shall be
               designated by Spire Capital Partners, L.P., (currently Andrew
               Armstrong) so long as such Stockholder and its affiliates
               continue to hold at least 536,586 shares of Series C Preferred
               Stock, as adjusted; provided, however, at such time that Spire
               Capital Partners, L.P. does not hold at least 536,586 shares of
               Series C Preferred Stock, as adjusted, the holders of a majority
               of the then outstanding of Series C Preferred Stock, voting as a
               separate class, shall designate the Series C Director.

The obligation to vote shares in accordance with this Section 7 shall be
specifically applicable to and enforceable against any transferees of the
parties hereto.

               (b)  Vacancies; Removal. In the event of any vacancy in the Board
                    ------------------
of Directors, each of the Stockholders agree to vote all shares of stock owned
or controlled by them and to otherwise use their best efforts to fill such
vacancy so that the Board of Directors of the Company will include directors
designated as provided in Section 7(a) above. Each of the Stockholders agrees to
vote all shares of stock owned by them for the removal of a director whenever
(but only whenever) there shall be presented to the Board of Directors the
written direction that such director be removed executed by the person or
persons entitled to designate such director pursuant to Section 7(a).

                (c) Meetings. The Board of Directors shall hold regularly
                    --------
scheduled meetings as determined by a majority of the Bo of Directors. The
Company will give each Director written notice at least three (3) days (24
hours, in the case of a telephone meeting) in advance of all meetings of the
Board of Directors and all meetings of committees of the Board of Directors. If
the Company proposes to take any action by written consent in lieu of a meeting
of its Board of Directors or any committee thereof, the Company shall give
written notice thereof to each such Director prior to the effective date of such
consent describing in reasonable detail the nature and the substance of such
action.

                (d) Expenses and Insurance. The Company shall reimburse all
                    ----------------------
persons serving as directors, consistent with the Company's policies for such
reimbursement, if any, for their actual and reasonable out-of-pocket expenses
incurred in attending meetings of the Board of Directors and all committees
thereof. In addition, the Company shall maintain directors' and officers'
liability insurance from reputable insurers of sound financial standing as
presently in effect or in such greater amounts as determined by the Company's
Board of Directors.

                (e) Compensation Committee of the Board of Directors. The Board
                    ------------------------------------------------
of Directors shall establish a compensation committee (the "Compensation
Committee") to which it shall delegate the authority to take all actions with
respect to the Option Plan. The Compensation Committee shall consist of five
members, one of which shall be a Common Director (it being agreed that so long
as such person shall be Art Zeile or Joel Daly, he shall vote on all matters
other than the compensation for such individuals) one of which shall be the
Series A Director, one of which shall be the Series

                                       9
<PAGE>

B Director, one of which shall be the Series C Director and one of which shall
be an Outside Director.

               8.   Legend. Each existing or replacement certificate for shares
                    ------
now owned by the Purchasers and Company Holders shall bear the following legend
upon its face:

               THE OWNERSHIP, VOTING, TRANSFER, ENCUMBRANCE, PLEDGE, ASSIGNMENT
               OR OTHER DISPOSITION OF THIS CERTIFICATE AND THE SHARES OF STOCK
               REPRESENTED THEREBY, ARE SUBJECT TO THE RESTRICTIONS CONTAINED IN
               A STOCKHOLDERS' AGREEMENT AMONG THE COMPANY AND CERTAIN
               STOCKHOLDERS. COPIES OF THE AGREEMENT MAY BE OBTAINED UPON
               WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY."

               9.   Public Offering.  In the event that the Board of Directors
                    ---------------
of the Company approves an initial public offering of the Common Stock of the
Company, each of the Company Holders shall take all necessary or desirable
actions in connection with the consummation of the initial public offering. In
the event that such public offering is an underwritten offering and the managing
underwriters advise the Company in writing that in their opinion the current
capital structure may adversely affect the marketability of the offering, each
of the Company Holders shall consent to and vote for a recapitalization,
reorganization and/or exchange of the Company's capital stock into securities
that the managing underwriters and the Board of Directors find acceptable and
shall take all necessary or desirable actions in connection with the
consummation of the recapitalization, reorganization and/or exchange; provided
that the resulting securities reflect and are consistent with the rights and
preferences set forth in the Company's Certificate of Incorporation as in effect
immediately prior to such public offering.

               10.  "Market Stand-Off" Agreement.  Each Company Holder hereby
                    ----------------------------
agrees to be bound by the provisions of Section 1.15 of that certain Fifth
Amended and Restated Investors' Rights Agreement dated as of the date hereof.

               11.  Notices.  All notices, demands or other communications to be
                    -------
given or delivered under or by reason of the provisions of this Agreement shall
be in writing and shall be deemed to have been given when delivered personally
to the recipient, sent to the recipient by reputable overnight courier service
(charges prepaid), or transmitted by facsimile or electronic mail (with request
for immediate confirmation of receipt in a manner customary for communications
of such type and with physical delivery of the communication being made by one
of the other means specified in this Section as promptly as practicable
thereafter).  Such notices, demands and other communications shall be addressed
(i) in the case of a Stockholder, to his or its address as is designated in
writing from time to time by such party, (ii) in the case of the Company, to its
principal office, and (iii) in the case of any transferee of a party to this
Agreement or its transferee, to such transferee at its address as designated in
writing by such transferee to the Company from time to time.

          12.  Assignment of Rights.  This Agreement and the rights and
               --------------------
obligations of the parties hereunder shall inure to the benefit of, and be
binding upon, the parties' respective successors, assigns and legal
representatives; provided, however, that the rights of the Stockholders
hereunder are only assignable to an assignee or transferee (i) who acquires all
of the securities of the Company held by the transferring Stockholder on the
date hereof or, if less than all, securities representing at least fifty percent
(50%) of the securities of the Company held by such transferring Stockholder as
of the date of this Agreement, or (ii) to a transferee described in the first
sentence of Section 5, and it shall be a requirement of such transfer that such
assignee shall then become a party to this Agreement.

          13.  Term.  This Agreement shall terminate upon the earlier of (i) the
               ----

               ----------------
understanding of the parties with respect to the subject matter hereof,
supersedes all other agreements between or among any of the parties with respect
to the subject matter hereof and cannot be altered or otherwise amended except
pursuant the terms of Section 17 below.  This Agreement shall be interpreted
under the laws of the State of Colorado without reference to its principles of
conflicts of law.

          15.  Attorneys' Fees.  If any action at law or in equity is necessary

          16.  Further Instruments and Actions.  The parties agree to execute
               -------------------------------
such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement.  The parties further agree
to cooperate affirmatively with the Company, to the extent reasonably requested
by the Company to enforce rights and obligations to this Agreement.

          17.  Amendments and Waivers.  Any term of this Agreement may be
               ----------------------
amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of at least seventy-five percent (75%) of the outstanding
Preferred Shares (and if any amendment or waiver by its terms adversely affects
the rights of the persons holding a particular series of the Preferred Shares
and not similarly the rights of holders of the other series of Preferred Shares,
the written consent of a majority in interest of the holders of outstanding
shares of such adversely affected series of Preferred Shares), provided,
however, that any amendment or waiver adversely affecting the rights of the
persons holding Common Shares and not similarly adversely affecting the rights
of holders of Preferred Shares shall require the written consent of a majority
in interest of the outstanding Common Shares.  Any amendment or waiver effected
in accordance with this Section shall be binding upon the Company and all
Stockholders and their respective successors and assigns.

          18.  Rights; Separability.  Unless otherwise expressly provided
               --------------------
herein, a Company Holder's rights hereunder are several rights, not rights
jointly held with any other Company Holder.  In case any provision of this
Agreement shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

          19.  Waiver of Jury Trial.  Each party hereto hereby waives trial by
               --------------------
jury in any legal action or proceeding relating to this agreement.

          20.  Other Covenants.  The Company covenants to each Preferred Holder
               ---------------
that has purchased at least $1,000,000 of Preferred Shares and that shall
continue to own at least 25% of the Preferred Shares that it holds as of the
date hereof, that the Company shall:

               (a) maintain its corporate existence; and

               (b) comply with applicable laws, except where failure to do so
would not reasonably be expected to have a material adverse effect on its
business, assets, operations, properties or financial condition.

          21.  Liquidation Events.  No Stockholder shall be permitted to sell,
               ------------------
assign or otherwise dispose of any stock to any Person in connection with a
Liquidation Event (as defined in the Company's Fifth Amended and Restated
Certificate of Incorporation) if such sale, assignment or disposition would
prevent the realization by the holders of Preferred Shares of the amounts
payable to them in accordance with Article IV(B)(2)(a) of the Company's Fifth
Amended and Restated Certificate of Incorporation.

                                       12
