Note 5 - Business Acquisitions

On July 1, 1999, ITHC entered into an agreement with Cognigen to purchase all of
Cognigen's net assets. The purchase price included 5,500 shares of ITHC common
stock ($.01 par value), a $300,000 note payable due October 1, 1999 and a four
year employment contract for the founder of Cognigen with an annual base salary
of $175,000. The transaction was accounted for as a purchase. ITHC acquired net
assets of $86,230 and recorded goodwill of $213,770. The goodwill will be
amortized over a life of 20 years.

On August 20, 1999, the Company completed the acquisition of all of the net
assets of ITHC in exchange for up to 49,041,397 shares of the Company's common
stock. For financial statement purposes, this business combination was accounted
for as an additional capitalization of ITHC (a reverse acquisition in which ITHC
was the accounting acquirer). ITHC is considered the surviving entity and the
historical financial statements prior to the acquisition are those of ITHC. The
Company's net book value prior to the transaction was $0. The issuance of the
stock must be completed in two closings due to the limited amount of authorized
stock available for issuance under the Company's articles of incorporation. The
first closing resulted in the issuance of 11,742,953 shares while the remaining
37,298,444 shares will be issued after a shareholder vote to increase the
authorized number of shares or after a reverse stock split is effected. The
Company issued 5,000,000 shares of the Company's common stock as finders' fees
in connection with the transaction to unrelated individuals.

Additionally on August 20, 1999, ITHC purchased 12,602,431 shares of the
Company's common stock for a price of $190,000 from certain existing
shareholders of the Company. This was recorded as a charge to equity in the
amount of $190,000.

The Company is the legal survivor and plans to change its name to Cognigen
Networks, Inc.

              Notes to Unaudited Consolidated Financial Statements

Note 6 - Stockholders' Equity

During the six months ended December 31, 1999, the Company received
subscriptions for 12,489,102 shares of the Company's common stock at prices of
$0.38 per share (11,562,302 shares) and $1.60 per share (926,800 shares) from
various persons. These shares were issued by March 31, 2000. The Company agreed
to pay a fee of 12% of the total proceeds received from the sale of the common
stock to a distributor and issue warrants to purchase up to a maximum of
1,500,000 shares of the Company's common stock to various persons in connection
with the sales. These warrants were valued at $347,400 based on a value of $.23
per warrant. This fee was accounted for as a cost of the reverse acquisition.
The Company paid a total of $727,474 related to the total fee due and other
expenses associated with the offering.

In August 1999, the Company issued 31,600,000 options entitling the holders to
purchase the Company's common stock at $0.46 per share. The options vest
immediately and expire five years from the date issued. The options cannot be
exercised until the Company amends it articles of incorporation or effects a
reverse split of its common stock so that it has sufficient shares available for
issuance upon the exercise of these options. 25,200,000 of these options were
issued to non employees while the remaining options were issued to employees and
directors. The Company has adopted the disclosure-only provisions of Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation." Accordingly, no compensation cost has been recognized for the
stock options issued to employees and directors. $5,836,724 of compensation
expense was recorded in connection with the options granted to non employees
based on a value of $.23 per option.


Note 7 - Related Party Activities

During the nine months ended March 31, 2000, the Company advanced $570,000 to a
company it had entered into a letter-of-intent to acquire. The Company completed
the acquisition in April of 2000 by issuing 2,041,445 shares of its common stock
for all of the stock of the company acquired.


Note 8 - Non-Cash Investing and Financing Activities

During the nine months ended March 31, 2000:

The Company acquired net assets of 86,230 and recorded goodwill on the amount of
$213,770 by issuing a note for $300,000 in connection with a business
acquisition (Note 5).

During the nine months ended March 31, 1999:

The Company issued notes of $1,300,000 in exchange for customer lists of
1,300,000.

            MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION


Forward-Looking Statements

Certain of the information discussed in this quarterly report, and in particular
in this section entitled "Management's Discussion and Analysis or Plan of
Operation," contains forward-looking statements that involve risks and
uncertainties that might adversely affect the operating results of Silverthorne
Production Company ("Company") in the future in a material way. Such risks and
uncertainties include, without limitation, rate changes, fee policy or
application changes and competition. Many of these risks are beyond the control
of the Company. The Company is not entitled to rely on the safe harbor
provisions of Section 27A of the Securities Act of 1933, as amended, or Section
21E of the Securities Exchange Act of 1934, as amended, when making
forward-looking statements.

Overview

The Company was incorporated on May 6, 1983, in Colorado. On August 20, 1999,
the Company completed the acquisition of all of the net assets of ITHC in
exchange for up to 49,041,397 shares of the Company's common stock. For
financial statement purposes, this business combination was accounted for as an
additional capitalization of ITHC (a reverse acquisition in which ITHC was the
accounting acquirer). For accounting purposes, ITHC is considered the surviving
entity and the historical financial statements prior to the acquisition are
those of ITHC. The Company's net book value prior to the transaction was $0.

Inter-American Telecommunications Holding Corporation (ITHC) was incorporated on
July 24, 1998 in Delaware. Since its inception, ITHC has directed its efforts
toward the acquisition of assets that would allow it to be engaged in direct and
multilevel agency marketing and sale of long distance service and products as
well as the switching and transport of voice, fax and data telephone and
internet traffic and related services. On July 1, 1999, ITHC acquired the net
assets of Cognigen Corporation (Cognigen) in exchange for 5,500 shares of its
common stock and a note payable of $300,000. Cognigen was actively marketing
long distance telephone services over the internet.

The Company intends to seek an increase in their authorized number of shares or
the authorization for a 1-2, 1-3 or 1-4 reverse stock split as the Board deems
appropriate. The Company intends to take these actions at its next annual
shareholder meeting anticipated to be held in June 2000.

            MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION


Results of Operations

ITHC was a developmental stage company since its inception on July 24, 1998
through June 30, 1999. During this stage, ITHC generated no revenues and
incurred only minimal operational costs. ITHC focused its efforts on the pursuit
of the acquisition of business opportunities. On July 1, 1999, ITHC completed
the acquisition of all the net assets of Cognigen in a transaction accounted for
as a purchase. Additionally, in a transaction accounted for as a reverse
acquisition, ITHC acquired control of the Company, a non-operating public shell
corporation. Therefore, the results of operations for the three and nine months
ended March 31, 2000 are comprised entirely of the operations generated from the
net assets purchased from Cognigen on July 1, 1999. As no operations existed for
ITHC for the three and nine month periods ended March 31, 1999, no meaningful
comparisons can be made.

For purposes of this Management's Discussion and Analysis or Plan of Operation,
the Company believes that the unaudited results of operations for Cognigen for
the three and nine months ended March 31, 1999 shown below provide a more
meaningful basis for analysis. Therefore, all comparisons and analysis included
in this Management's Discussion and Analysis or Plan of Operation are based
upon these unaudited results of operations for Cognigen for the three and nine
months ended March 31, 1999.

            MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION


Three Months Ended March 31, 2000 Compared to Three Months Ended March 31, 2000.

Total revenue for the three months ended March 31, 2000 was $908,598 compared to
$504,212 for the three months ended March 31, 1999. Total revenue for the 2000
period consisted of $82,632 related to prepaid cards and pins and $707,193
related to commissions. Total revenue for the comparable period in 1999
consisted of $226,616 related to prepaid cards and pins and $277,596 related to
commissions. The $143,984, or 63%, decrease in prepaid cards and pins is due to
reduced tariff calls as a result of competition. The $429,597, or 155%, increase
in commissions is due to an increase in agents of 20% or 236 new agents.

Operating costs related to prepaid cards and pins for the three months ended
March 31, 2000 decreased $23,085, or 12%, to $170,798 from $193,883 during the
three months ended March 31, 1999. Operating costs related to commissions for
the three months ended March 31, 2000 increased $251,728, or 123%, to $457,062
from $205,334 during the three months ended March 31, 1999. The cost increases
are directly related to the increases in sales revenue

General and administrative operating expenses increased $687,950, or 498%, to
$826,184 during the three months ended March 31, 2000 from $138,234 during the
three months ended March 31, 1999. This increase is due to increased salaries of
$164,706 or 182% as a result of more headcount, increased legal and professional
expenses of $101,031 or 131% due to acquisitions and increased commissions paid
of $51,200 or 13%.

The Company incurred a loss from operations of $545,446 for the three months
ended March 31, 2000 compared to $33,239 for the three months ended March 31,
1999. The decrease in operating loss during the current period is directly
related to the increase in general and administrative expenses discussed above.

Net interest income for the three months ended March 31, 2000 of $2,935 compares
to net interest income during the same three months ended March 31, 1999 of $0.
The reason for this increase is due to larger cash balances earning interest
from an increase in deposits. After interest income, the net loss for the three
months ended March 31, 2000 was $542,511, or $.01 loss per share, compared to
net income of $33,239 for the three months ended March 31, 1999.

Nine Months Ended March 31, 2000 Compared to Nine Months Ended March 31, 1999

Total revenue for the nine months ended March 31, 2000 was $2,592,189 compared
to $1,091,710 for the nine months ended March 31, 1999. Total revenue in 2000
consisted of $846,427 related to prepaid cards and pins and $1,642,400 related
to commissions. Total revenue for the comparable period in 1999 consisted of
$657,003 related to prepaid cards and pins and $434,707 related to commissions.
The $189,424, or 29%, increase in prepaid cards and pins is due to an increase
in sales agents of approximately 800 agents. The $1,207,693, or 278%, increase
in commissions is also directly related to the increase in agents.

to $7,726,564 during the nine months ended March 31, 2000 from $359,023 during
the nine months ended March 31, 1999. This increase is due to a non-cash charge

salaries resulting from significant Company growth and increased legal and
professional costs from business acquisitions and related public filings.

The Company incurred a loss from operations of $7,043,439 for the nine months

                         SILVERTHORNE PRODUCTION COMPANY

            MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION


The Company currently has three notes with total outstanding blanaces of
$690,000. Two of these notes are due in July 2000 while the remaining note is
due November 2000.

The Company believes its current liquidity requirement primarily will be to meet
working capital requirements. The Company has no planned significant capital
expenditures in the foreseeable future. Cash generated from operations was not
sufficient to meet working capital requirements for the nine months ended March
31, 2000, and may not be sufficient to meet working capital requirements for the
foreseeable future. Therefore, additional debt or equity financing may be
required for the Company to satisfy its short term capital needs. There can be
no assurances that the Company will be able to generate additional debt or
equity financing if needed.

The Company advanced $570,000 to Aquila International Telecommunications, Inc.
(Aquila) in connection with a carrier service agreement.  This agreement was for
performing services for migrating customers from the Company's customer lists
to active status, switching services and full customer maintenance.  The Company
acquired all of the outstanding common stock of Aquila in April 2000 by issuing
2,041,445 shares of its common stock.  The required financial statements and
pro forma information will be included in the Company's Current Report on
Form 8-K/A anticipated to be filed with the Securities and Exchange Commission
within the required timeline.
