EXECUTION VERSION


Shareholders, be converted into a number of shares of Parent Series F Preferred
Stock equal to the Exchange Ratio as of the Effective Time multiplied by ten
(10) and reduced to reflect the applicable option or warrant exercise price; and
(iii) in lieu of any right of redemption, each share of Company Redeemable
Preferred Stock that is issued and outstanding immediately prior to the
Effective Time shall, by virtue of the Merger and without any action on the part
of the Company Shareholders, be converted into a Preferred Note equal to a
proportionate share of the PN Amount based on the liquidation preference for
such shares of Company Redeemable Preferred Stock held by each holder.
Notwithstanding the foregoing, each warrant for Company stock which as of the
Effective Date has not been exercised, whether such warrant is for Company
common stock or any series of Company preferred stock, shall receive an amount
of Merger Consideration which reflects a discount for any unpaid exercise price
applicable to such warrant. The Parties agree that as of the date of this
Agreement the Exchange Ratio and the calculation thereof is as set forth in
Exhibit I. Before applying the Exchange Ratio for the Effective Time pursuant to
any provision of this Section 3, each component thereof which is defined in this
Agreement will, subject to the provisions of Section 3.3, be recalculated as of
such time to reflect changes in the amount of issued and outstanding capital
stock, options and warrants for capital stock of Parent and such Exchange Ratio
will be used to compute the initial Merger Shares to be issued to the holders of
the Company Capital Stock as of the Effective Time.

              (b)  Final Exchange.  Within five (5) days after the IPO, the
parties will recalculate the Exchange Ratio as of the time immediately prior to
the IPO (the "Final Exchange Ratio"). The Parent will deliver by virtue of the
Merger and without any action by the Company Shareholders the number of
additional shares of the Parent's common stock necessary to cause each Company
Shareholder holding Company Capital Stock to receive shares of Common Stock
(including Common Stock received on the conversion of the Parent Series F
Preferred Stock) that such Company Shareholder would have received if the Final
Exchange Ratio had been used to compute the shares received under clauses (i)
and (ii) of Section 3(a).

              (c)  Calculations. Notwithstanding the provisions of Sections
3.1(a) and Section 3.1(b), in calculating the Exchange Ratio, options issued to
the employees of the Company or the Parent between the date of this Agreement
and the Effective Time will only be taken into account to the extent that such
options granted by the Parent exceed One Million Two Hundred Thousand
(1,200,000) shares with respect to options granted to a newly hired Chief
Operational Officer of Parent and Five Hundred Thousand (500,000) shares with
respect to other grants, and that such options granted by the Company exceed
Twenty Five Thousand (25,000) shares. Company hereby represents and warrants to
Parent and Sub that as of the Effective Time there shall be no capital stock of
Company, or any security convertible into capital stock of the Company, which
carries any right of redemption by the holder thereof with the exception of
Company's Redeemable Preferred Stock

         3.2  Company Options.  In addition to the provisions of Section 3.1,
at the Effective Time, each of the then outstanding option to purchase Company
Capital Stock, whether vested or unvested, (collectively, the "Company Options")
(including all outstanding options granted under the Company's 1999 Plan (the
"Company Plan"), and any individual non-plan options not converted pursuant to
Section 3.1) and the Company Plan will by virtue of the Merger, and without any
further action on the part of any holder thereof, be assumed by Parent and
converted into options to purchase that whole number of shares of Parent Series
F Preferred Stock determined by multiplying the number of shares of Company
Capital Stock subject to such Company Option at the Effective Time by the
Exchange Ratio, at an exercise price per share of Parent Series F Preferred
Stock equal to the exercise price per share of such Company Option immediately
prior to the Effective Time divided by the Exchange Ratio, rounded up to the
nearest cent. If the foregoing calculation results in an assumed Company Option
being exercisable for a fraction of a share of Parent Series F Preferred Stock,
then the number of shares of Parent Series F Preferred Stock subject to such
option will be rounded to the nearest whole number of shares. Except as
expressly stated otherwise in this Agreement, the Parties agree that the term,
exercisability, vesting schedule, vesting commencement date, status as an
"incentive stock option" under Section 422 of the Code, if applicable, and all
other terms and conditions of the Company Options will otherwise be unchanged as
a result of the transactions contemplated by this Agreement. Without limiting
the foregoing, Company further hereby represents and warrants to Parent that no
Company Options shall vest, nor shall the vesting schedule of any Company
Options accelerate, as a result of the transactions contemplated by this
Agreement, except as follows (the "Accelerated Stock Rights"): (a) 75,000
Company Options held by Arthur Klebanoff; (b) 75,000 Company Options held by
Caroline Vanderlip; (c) 20,000 Company Options held by Allison Dollar; (d)
75,000 Company Options held by Michael Grandfield; (e) 250,000 Company Options
held by Robert Rankin; and (f) 250,000 Company Options held by Vaughn Rachal
(unless modified by amendment to Mr. Rachal's employment agreement). Company
hereby represents and warrants to Parent that none of the aforementioned
persons, other than Robert Rankin or Vaughn Rachal, is now or will be as of the
Effective Time an employee of Company. Parent agrees that for all Company
Options which, pursuant to the Merger are converted into options to acquire
Parent Series F Preferred Stock, the Common Stock into which the resulting
shares of Parent Series F Preferred Stock are convertible will be included by
Parent in any S-8 filing made by Parent with the SEC and as a result all of such
Common Stock will freely salable without restriction or further registration.
Within five (5) days after the IPO, Parent shall recalculate the conversion of
the Company Options by applying the Final Exchange Ratio, such that each Company
Option holder is in the same position such holder would have been in had the
Final Exchange Ratio been applied at Effective Time (including without
limitation an adjustment of the Exercise Price using the Final Exchange Ratio).

effecting the surrender of the Certificates in exchange for the Merger Shares.
Upon surrender of a Certificate for cancellation to the Exchange Agent or to
such other agent or agents as may be appointed by Parent, together with such
letter of transmittal and a Shareholder Certificate in the form of Exhibit D,
duly executed, the holder of such Certificate shall be entitled to receive in
exchange therefor the number of Merger Shares to which the holder of Company
Capital Stock is entitled pursuant to Section 3.1 hereof. The Certificates so
surrendered shall forthwith be canceled. Except as expressly provided in the
Preferred Notes, no interest will accrue or be paid to the holder of any
outstanding Company Capital Stock, other than as provided in the Preferred

dividends or other distributions declared or made after the Effective Time with
respect to Parent Series F Preferred Stock with a record date after the
Effective Time will be paid to the holder of any unsurrendered Certificate with
respect to the shares of Parent Series F Preferred Stock represented thereby
until the holder of record of such Certificate shall surrender such Certificate.
Subject to applicable law, following surrender of any such Certificate, there
shall be paid to the record holder of the certificates representing whole shares
of Parent Series F Preferred Stock issued in exchange therefor, without
interest, at the time of such surrender, the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid with
respect to such whole shares of Parent Series F Preferred Stock.

              (e)  Transfers of Ownership.  If any certificate for shares of
Parent Series F Preferred Stock is to be issued in a name other than that in
which the Certificate surrendered in exchange therefor is registered, it will be
a condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the Person
requesting such exchange will have paid to Parent or any agent designated by it
any transfer or other taxes required by reason of the issuance of a certificate
for shares of Parent Series F Preferred Stock in any name other than that of the
registered holder of the Certificate surrendered, or established to the
satisfaction of Parent or any agent designated by it that such tax has been paid
or is not payable.

              (f)  Lost, Stolen or Destroyed Certificates.  In the event that
any Certificates shall have been lost, stolen or destroyed, the Exchange Agent
shall issue in exchange for such lost, stolen or destroyed Certificates, upon
the making of an affidavit of that fact by the holder thereof, such shares of
Parent Series F Preferred Stock as may be required pursuant to Sections 3.1 and
3.2 hereof; provided, however, that Parent may, in its discretion and as a

Effective Time and the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive Parent

upon surrender of the certificate representing such shares.

              (c)  The Company shall give Parent (i) prompt notice of any
written demands for appraisal of any shares of Company Capital Stock,
withdrawals of such demands, and any other instruments served pursuant to
Oklahoma Corporate Law and received by the Company and (ii) the opportunity to
participate in all negotiations and proceedings with respect to demands for

         3.7  Contingent Consideration.

              (a) For purposes of this Agreement: (i) "Budgeted Revenue" shall
mean the budgeted revenue of the Company as projected in the "webcasts.com
revenue plan" dated as of January 10, 2000 attached hereto as Exhibit K (the
"Revenue Plan") earned between April 1, 2000 and April 1, 2001 (the "Earn Out
Date"), calculated in accordance with GAAP; and (ii) "Notice Representative"
shall mean that person designated in writing by the Company Shareholders as
their representative with respect to this Section 3.8. The Company hereby
designates John Frick as the Notice Representative until such time as the
Company Shareholders designate another person as the Notice Representative.

              (b) If by the Earn Out Date, the Company achieves revenue,
calculated in accordance with GAAP, of at least seventy percent (70%) but less
than ninety five percent (95%) of Budgeted Revenue, then within twenty (20) days
after the Earn Out Date Parent shall issue, as additional Merger Consideration,

and place acceptable to Parent in its reasonable discretion, Parent's financial
information pertaining to the determinations made by Parent pursuant to Section

such objection shall be submitted to arbitration pursuant to the applicable
rules of the American Arbitration Association, such arbitration shall be
conducted in Sunnyvale, California.  The results of such arbitration shall be
binding on the parties.  If no timely objections are made, then the Parent's

then within ten (10) business days after such date Parent shall issue, in lieu
of and not in addition to the issuances described in Section 3.7(b) and Section
3.7(c), as additional Merger Consideration an aggregate number of shares of
Parent Series F Preferred Stock equal to one percent (1.0%) of the Parent's
issued and outstanding capital stock as of May 31, 2000. Parent shall deliver
such additional Merger Consideration to the Notice Representative for delivery
to the parties entitled to receive same.

              (f) The obligation of Parent to issue shares as additional Merger
Consideration pursuant to this Section 3.7 shall not be subject to set-off for
claims Parent has or may have against the Persons entitled to receive such
shares.

              (g) In addition to the rights and obligations applicable to Parent
Series F Shares, Parent shall use its Best Efforts to register under applicable
Federal securities laws all shares issued pursuant to this Section 3.7.

              (h) Parent and the Surviving Corporation shall make such
expenditures as are consistent with the Revenue Plan.

stock.

EXECUTION VERSION


              (j) Any additional Merger Consideration to be delivered pursuant
to Section 3.7(b), Section 3.7(c), or Section 3.7(e) shall be allocated among
the Persons entitled to receive same in accordance with their respective
holdings of Company Capital Stock and Company Options as of the Effective Time.
Parent agrees to adjust the exercise price of any Company Options downward to
reflect any increase in the Merger Consideration pursuant to this Section 3.

         3.8  Further Action.  Parent, Sub and the Company shall take all such
actions as may be necessary or appropriate in order to effect the Merger as
promptly as possible. If, at any time after the Effective Date, any further
action is necessary or desirable to carry out the purposes of this Agreement and
to vest the Surviving Corporation with full right, title and possession to all
assets, property, rights, privileges, powers and franchises of the Company, the
officers and directors of such corporation are fully authorized in the name of
the corporation or otherwise to take, and shall take, all such action.

         4.  Securities Act Compliance.  Parent intends that the shares of
Parent Series F Preferred Stock issued in connection with the Merger will be
issued in a transaction exempt from registration under the Securities Act of
1933, as amended (the "Securities Act"), by reason of Rule 506 of Regulation D
promulgated under Section 4(2) of the Securities Act. The certificates for the
shares of Parent Series F Preferred Stock to be issued in the Merger shall bear
appropriate legends to identify such privately placed shares as being restricted
under the Securities Act, to comply with applicable state securities laws and,
if applicable, to notice the restrictions on transfer of such shares. It is
acknowledged and understood that Parent is relying upon certain written
representations made by the Company Shareholders in the Shareholder Certificates
in substantially the form attached hereto as Exhibit D. In the event that Parent
and its representatives and advisers reasonably determine that Rule 506 of
Regulation D is unavailable to Parent to exempt the issuance of the Parent
Series F Preferred Stock in connection with the Merger from registration under
the Securities Act, Parent, in its sole discretion, may seek to exempt the
Series F Preferred Stock issued in connection with the Merger from the
requirements of the Securities Act pursuant to Section 3(a)(10) of the
Securities Act through a fairness hearing conducted in the State of California
(a "3(a)(10) Proceeding"). In the event that Parent succeeds in exempting the
Series F Preferred Stock through a 3(a)(10) proceeding, and as a result thereof
the Parent Series F Preferred Stock and any Common Stock to be received on
conversion of the Parent Series F Preferred Stock are and will not be subject to
restriction on resale or further registration requirements under Federal
securities laws, the rights of Company Shareholders under the Second Amended and
Restated Investors Rights Agreement shall terminate and be of no further force
and effect; provided however that Company Shareholders, who (i) at the Closing
are Affiliates of the Company, or (ii) become Affiliates of Parent after the
Closing and continue to be Affiliates of Parent, shall continue to have the
rights and obligations set forth in the Second Amended and Restated Investors
Rights Agreement under the terms of such Agreement.

arbitration, or investigation of, in, or before any court or quasi-judicial or
administrative agency of any federal, state, local, or foreign jurisdiction or
before any arbitrator. To the Knowledge of Parent, there are no facts or
circumstances which would form the basis of any claim against Parent. No
Governmental Body has at any time challenged or questioned in a writing
delivered to Parent the legal right of Parent to design, manufacture, offer or
sell any of its products or services in the present manner or style thereof.

         6.9 Brokers' Fees. Parent does not have any liability or obligation to

Registered Intellectual Property Rights owned by, filed in the name of, or
applied for, by the Company (the "Parent Registered Intellectual Property
Rights") and lists any proceedings or actions before any court, tribunal
(including the PTO or equivalent authority anywhere in the world) related to any
of the Parent Registered Intellectual Property Rights or Parent Intellectual
Property.

              (b) Each item of Parent Registered Intellectual Property Rights is
valid and subsisting, and all necessary registration, maintenance and renewal
fees in connection with such Parent Registered Intellectual Property Rights have
been paid and all necessary documents and certificates in connection with such
Parent Registered Intellectual Property Rights have been filed with the relevant

filing of any responses to PTO office actions, documents, applications or
certificates for the purposes of obtaining, maintaining, perfecting or

Property Right from any person, the Parent has obtained a valid and enforceable

EXECUTION VERSION


accordance with, applicable laws and regulations, the Parent has recorded each
such assignment of a Registered Intellectual Property Right assigned to the
Parent with the relevant Governmental Body, including the PTO, the U.S.
Copyright Office, or their respective equivalents in any relevant foreign
jurisdiction, as the case may be. The Parent has claimed "Small Entity Status"
in the patent application and to the Parent's Knowledge, such claim will remain
true and accurate despite the Closing.

              (c) The Parent has no Knowledge of any facts or circumstances that
would render any Company Intellectual Property invalid or unenforceable. To the
Parent's knowledge, each item of Company Intellectual Property is free and clear
of any Security Interests except for non-exclusive licenses granted in the
Ordinary Course of Business and the Parent is the exclusive owner or exclusive
licensee (except for any rights reserved by the licensor) of all Parent
Intellectual Property. To the Parent's Knowledge, all Parent Intellectual
Property, except with respect to those Intellectual Property Rights which may be
personal and non-transferable, will be fully transferable, alienable or
licensable by Surviving Corporation and/or Parent without restriction and
without payment of any kind to any third party.

              (d) To the Parent's Knowledge, to the extent that any Parent
Technology has been developed or created by a third party for the Parent, the
Parent has a written agreement with such third party with respect thereto,
either (i) conveying ownership to the Parent of such Intellectual Property,
except with respect to those Intellectual Property Rights which may be personal
and non-transferable, or (ii) granting a license to the Parent of such
Registered Intellectual Property.

              (e) To the Parent's Knowledge, with exception of "shrink-wrap"
licenses, or other end-user licenses for third-party software technology used in
the conduct of Parent's business as presently conducted by the Parent was
written and created solely by either (i) employees of the Parent acting within
the scope of their employment or (ii) by third parties from which the Parent has
obtained an assignment which to the best of Parent's Knowledge is valid.

              (f) To the Parent's Knowledge, all employees of the Parent have
entered into a written agreement with the Parent assigning to the Parent of all
Technology, including all accompanying Intellectual Property Rights, created by
such employee in the scope of his or her employment with the Parent, subject to
exceptions as may be specified in such agreements.

              (g) To the Parent's Knowledge, the Parent has taken reasonable
steps to protect the Parent's rights in confidential information and trade
secrets of the Parent or provided by any other person to the Parent. Without
limiting the foregoing, the Parent has, and to its knowledge enforces, a policy
requiring each employee, consultant and contractor to execute a proprietary
information, confidentiality and assignment agreement, substantially in the
forms attached hereto as Section 6.10(i) of the Parent Disclosure Schedule.

              (a) Parent has filed all reports and returns with respect to any
Taxes ("Parent Tax Returns") that it was required to file. All Parent Tax
Returns were prepared in accordance with all applicable statutes, rules and
regulations. To Parent's Knowledge, no Parent Tax Returns are currently the
subject of audit or examination nor has Parent been notified of any request for
an audit or examination. All Taxes owed by Parent (whether or not shown on any
Parent Tax Return) were paid in full when due or are being contested in good
faith and are supported by adequate reserves on the Parent Financial Statements.
Parent has provided adequate reserves on the Parent Financial Statements for the
payment of any taxes accrued but not yet due and payable as of the dates of the
Parent Financial Statements. Parent is not currently the beneficiary of any
extension of time within which to file any Parent Tax Return, and Parent has not

of time with respect to any Tax assessment or deficiency.

              (b) There is no dispute, claim or proposed adjustment concerning
any Tax liability of Parent either (i) claimed or raised by any authority in

Parent is not a party to nor has it been notified that it is the subject of any
pending, proposed or threatened action, investigation, proceeding, audit, claim
or assessment by or before the Internal Revenue Service or any other
governmental authority and no claim for assessment, deficiency or collection of
Taxes, or proposed assessment, deficiency or collection from the Internal
Revenue Service or any other governmental authority which has not been
satisfied, nor does Parent have any reason to believe that any such notice will
be received in the future. The Internal Revenue Service has never audited any
federal income tax return of Parent. Parent has not filed any requests for
rulings with the Internal Revenue Service. No power of attorney has been granted
by Parent or any of its Affiliates with respect to any matter relating to Taxes
of Parent. There are no tax liens of any kind upon any property or assets of
Parent, except for inchoate liens for taxes not yet due and payable.

              (c) Parent has not filed a consent under Sec. 341(f) of the Code
concerning collapsible corporations. Parent has not made any payments, is not

any circumstances could obligate it to make any payments as a result of the
consummation of the Merger that will not be deductible under Code Sec. 280G.

transferee or successor, by contract, or otherwise. Parent has not requested or
received a ruling from any taxing authority or signed a closing agreement with
any taxing authority. To Parent's Knowledge, no claim has ever been made by a
taxing authority in a jurisdiction where Parent does not file Tax returns that
Parent is or may be subject to taxation by such jurisdiction.

              (d) The unpaid Taxes of Parent (i) did not, as of the close of
Parent's most recent taxable year, exceed by any amount the reserve for Tax
liability (other than any reserve for deferred taxes established to reflect
timing differences between book and tax income) set forth on the face of
Parent's Financial Statements (rather than in any notes thereto) and (ii) will
not exceed that reserve as adjusted for operations and transactions through the
Closing Date in accordance with the past custom and practice of Parent in filing
its Tax Returns.

insurance policy (including policies providing property, casualty, liability,
and workers' compensation coverage and bond and surety arrangements) with
respect to which Parent is a party, a named insured, or otherwise the
beneficiary of coverage. With respect to each such insurance policy: (A) the
policy is legal, valid, binding, enforceable, and in full force and effect (and
there has been no notice of cancellation or nonrenewal of the policy received by
Parent); (B) neither Parent nor, to Parent's Knowledge, any other party to the
policy is in breach or default under such policy (including with respect to the
payment of premiums or the giving of notices), and, to Parent's Knowledge, no
event has occurred which, with notice or the lapse of time, would constitute
such a breach or default, or permit termination, modification, or acceleration,
under the policy; (C) no party to the policy has repudiated any provision
thereof; and (D) there has been no failure by Parent to give any notice or
present any claim under the policy in due and timely fashion. Section 6.16 of

of this Agreement under Section 11.1 above will be effective immediately upon
the delivery of written notice of the terminating party to the other parties
hereto.  In the event of the termination of this Agreement as provided in
Section 11.1, this Agreement shall be of no force or effect, except (i) Section
11.2, Section 11.3 (Fees and Expenses), Section 7.8 (Confidentiality) and
Section 12 (Miscellaneous), will survive the termination of this Agreement, and
(ii) nothing herein shall relieve any Party from liability due to breach by
such Party of any of its representations, warranties or covenants set forth in
this Agreement.

         11.3  Fees and Expenses.

               (a)  General.  Each Party will bear its own costs and expenses
(including legal and accounting fees and expenses) incurred in connection with

reason or in a manner other than as specified in Section 11.1 hereof, the
Company shall pay to Parent an amount equal to $10 million within one business
day after written notice of such event.  Notwithstanding the foregoing, no
amount shall be due and owing to the Parent from the Company based on the terms
of this Section 11.3(b) in the event that the Company fully complies with the
provisions of Section 7.6 of this Agreement (Shareholder Approval), but the
vote or consent of a sufficient amount of the Company Shareholders necessary to
approve this Agreement and the Merger is not obtained by  April 1, 2000.
Further, Parent shall not be entitled to such break-up fee if the conduct of
the Company which is the basis of such break-up fee results from a breach of
this Agreement by Parent.

               (c)  Parent Break-Up Fee.  If (i) the Board of Directors of the
Parent shall have withheld, withdrawn or modified in a manner adverse to the
Company, its recommendation in favor of adoption and approval of this Agreement

Company $10 million within one business day of  delivery of  written notice of
such termination.  Notwithstanding the foregoing, no amount shall be due and

Preferred Stock or (ii) amend its Investors' Rights Agreement to provide for
the granting of registration rights to the Company Shareholders. Further, the

          12.1  Press Releases and Public Disclosure.  No Party shall issue any
press release or make any public disclosure relating to the subject matter of
this Agreement prior to the Closing without the prior written approval of the
other Party; provided, however, that Parent may make any public disclosure it
believes in good faith is required by applicable law or any listing or trading
agreement concerning its securities (in which case Parent will use its Best
Efforts to advise the Company prior to making the disclosure), securities laws
or exchange requirements, then Parent shall use its Best Efforts to provide the
Company prior notice of such disclosure.

          12.2  No Third-Party Beneficiaries.  This Agreement shall not confer
any rights or remedies upon any Person other than the Parties, the Company
Shareholders and their respective successors and permitted assigns.

          12.3  Entire Agreement and Modification.  This Agreement (including
the exhibits hereto) constitute the entire agreement among the Parties with

executed by all Parties and after the Effective Time except by a written
agreement signed by Parent.

          12.4  Succession and Assignment.  This Agreement shall be binding
upon and inure to the benefit of the Parties named herein and their respective
successors and permitted assigns.  No Party may assign either this Agreement or
any of its rights, interests, or obligations hereunder without the prior
written approval of the other Parties; provided, however, that Parent may (i)
assign any or all of its rights and interests hereunder to one or more of its
Affiliates and (ii) designate one or more of its Affiliates to perform its
obligations hereunder.

          12.5  Counterparts.  This Agreement may be executed in counterparts,

          12.8  Governing Law.  This Agreement shall be governed by and

as a waiver of such right, power or privilege, and no single or partial
exercise of such right, power, or privilege will preclude any other or further
exercise of such right, power, or privilege or the exercise of any other right,
power, or privilege.  To the maximum extent permitted by applicable law, (a) no
claim or right arising out of this Agreement or the documents referred to in

referred to in this Agreement.

          12.11  Severability.  Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect

situation or in any other jurisdiction.

          12.12  Construction.  The Parties have participated jointly in the
negotiation and drafting of this Agreement.  In the event an ambiguity or

local, or foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise.  The
