BERTHEL GROWTH & INCOME TRUST I
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE A - BASIS OF PRESENTATION
The accompanying unaudited financial statements have been prepared in accordance
with accounting principles generally accepted in the United States of America
for interim financial information and with the instructions to Form 10-Q and
Article 10 of Regulation S-X. Accordingly, they do not include all information
and footnotes required by generally accepted accounting principles for complete
financial statements and should be read in conjunction with the Trust's Form
10-K filed with the Securities and Exchange Commission for the year ended
December 31, 2005. In the opinion of management, all adjustments (consisting of
normal recurring accruals) considered necessary for a fair representation have
been included. Operating results for the three months ended March 31, 2006 are
not necessarily indicative of the results that may be expected for the year
ended December 31, 2006.

The preparation of the Trust's financial statements in conformity with
accounting principles generally accepted in the United States of America
necessarily requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

The Trust continues to have a deficiency in net assets. Berthel SBIC, LLC
("SBIC"), a wholly owned subsidiary of the Trust, has agreed to liquidate its
portfolio assets in order to pay its indebtedness to the United States Small
Business Administration ("SBA").

In August 2002, the SBA notified the SBIC that all debentures, accrued interest
and fees were immediately due and payable. The SBIC was transferred into the
Liquidation Office of the SBA at that time. On September 1, 2003, management
signed a loan agreement with the SBA for $8,100,000 (after paying $1,400,000 on
the $9,500,000 debentures) with a term of 48 months at an interest rate of
7.49%. The Agreement requires principal payments on the debt to the extent the
SBIC receives cash proceeds exceeding $250,000 for the sale or liquidation of
investments. As of March 31, 2006, $5,122,326 is outstanding under the loan
agreement, which is secured by substantially all assets of the SBIC. The loan
agreement contains various covenants, including limits on the amounts of
expenses, other than interest expense, that can be incurred and paid. The loan
agreement also contains various events of default, including a decrease in the
aggregate value of the SBIC's assets of 10% or greater.

As of March 31, 2006, total assets and liabilities of the Trust are $7,372,925
and $12,693,989, respectively. These factors raise substantial doubt about the
ability of the Trust to continue as a going concern. No assurance can be given
that the Trust will have sufficient cash flow to repay the debt or that the
Trust will be financially viable.

NOTE C - NOTES PAYABLE
The SBIC issued debentures payable to the SBA totalling $9,500,000 since
inception. The original debenture terms required semiannual payments of interest
at annual interest rates ranging from 6.353% to 7.64%. In addition to interest
payments, the SBIC was required to pay an annual 1% SBA loan fee on the
outstanding debentures balance.

In August 2002, the SBA notified the SBIC that all debentures, accrued interest
and fees were immediately due and payable. The SBIC was transferred into the
Liquidation Office of the SBA at that time. On September 1, 2003, management
signed a loan agreement with the SBA for $8,100,000 (after paying $1,400,000 on
the $9,500,000 debentures) with a term of 48 months at an interest rate of
7.49%. The Agreement requires principal payments on the debt to the extent the
SBIC receives cash proceeds exceeding $250,000 for the sale or liquidation of
investments. As of March 31, 2006, $5,122,326 is outstanding under the loan
agreement, which is secured by substantially all assets of the SBIC. The loan
agreement contains various covenants, including limits on the amounts of
expenses, other than interest expense, that can be incurred and paid. The loan
agreement also contains various events of default, including a decrease in the
aggregate value of the SBIC's assets of 10% or greater.

           ---------------------------------------------------------------
           Results of Operations
           ---------------------

Results of Operations
Net investment income (loss) reflects the Trust's revenues and expenses
excluding realized and unrealized gains and losses on portfolio investments.
Interest income consists of the following:

                               Three Months Ending March 31
                                   2006              2005

                               -----------       -----------
     Interest income           $    18,313       $    51,541
                               ===========       ===========

     Dividend income           $     4,167       $    30,819
                               ===========       ===========

Changes in interest earned on portfolio investments reflect the level of
investment in interest earning debt securities and loans. Money market interest
is earned on investments in highly liquid money market savings funds. Dividend
income reflects dividends earned on preferred stock investments.

Management fees, calculated as 2.5% of the combined temporary investment in
money market securities and loans and investments balances, were $49,574 for the
first three months of 2006 and $52,022 the same period a year ago. These fees
are currently accrued as payable to the Trust Advisor but are not paid, in
accordance with the loan agreement with the SBA.

Professional fees were $11,659 for the first three months of 2006 compared to
$8,614 for 2005 and include legal and accounting fees. Other general and
administrative expenses were $11,403 for the first three months of 2006 compared
to $11,439 for 2005. Interest expense was $102,118 for the first three months of
2006 and $137,164 for the same period of 2005 and is interest on the note
payable to the SBA.

The Trust continues to have a deficiency in net assets, as well as net
investment losses. In addition, the SBIC is in violation of the maximum capital
impairment percentage permitted by the SBA. In August, 2002, the SBA notified
the SBIC that all debentures, accrued interest and fees were immediately due and
payable. The SBIC was transferred into the Liquidation Office of the SBA at that
time. On September 1, 2003, management signed a loan agreement with the SBA for
$8,100,000 (after paying $1,400,000 on the $9,500,000 debentures) with a term of
48 months at an interest rate of 7.49%. The loan is secured by substantially all
assets of the SBIC. The loan agreement contains various covenants including
establishment of a reserve account in the amount of $250,000 with excess cash
paid to the SBA, limits on the amounts of expenses, other than interest expense,
that can be incurred and paid. The loan agreement also contains various events
of default, including a decrease in the aggregate value of the SBIC's assets of
10% or greater.

As of March 31, 2006, total assets and liabilities of the Trust are $7,372,925
and $12,693,989, respectively. These factors raise substantial doubt about the
ability of the Trust to continue as a going concern. No assurance can be given
that the Trust will have sufficient cash flow to repay the debt or that the
Trust will be financially viable.

The change in unrealized and realized gains and losses is summarized in the

The change in the unrealized gains and losses are the result of carrying the
Trust's portfolio of loans and investments at fair value. The fair value of the
loans and investments are approved by the Independent Trustees, and in the case
of the SBIC, are in accordance with SBA regulations. The Trust recognizes
realized gains and losses when investments have been either sold or written off
as deemed to be worthless. Securities that are traded publicly are valued at the
market price less any appropriate discount for reasons of liquidity or
restrictions.

Liquidity and Capital Resources
The Trust continues to have a deficiency in net assets, as well as net
investment losses. In addition, the SBIC is in violation of the maximum capital
impairment percentage permitted by the SBA. In August, 2002, the SBA notified
the SBIC that all debentures, accrued interest and fees were immediately due and
payable. The SBIC was transferred into the Liquidation Office of the SBA at that
time. On September 1, 2003, management signed a loan agreement with the SBA for
$8,100,000 (after paying $1,400,000 on the $9,500,000 debentures) with a term of
48 months at an interest rate of 7.49%. The loan is secured by substantially all
assets of the SBIC. The loan agreement contains various covenants including
establishment of a reserve account in the amount of $250,000 with excess cash
paid to the SBA, limits on the amounts of expenses, other than interest expense,
that can be incurred and paid. The loan agreement also contains various events
of default, including a decrease in the aggregate value of the SBIC's assets of
10% or greater.

The loan agreement with the SBA is due as follows:

                       Maturity Date                Amount
                       -------------                ------
                     September 1, 2007            $5,122,326

As of March 31, 2006, total assets and liabilities of the Trust are $7,372,925
and $12,693,989, respectively. These factors raise substantial doubt about the
ability of the Trust to continue as a going concern. No assurance can be given
that the Trust will have sufficient cash flow to repay the debt or that the
Trust will be financially viable.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
        ----------------------------------------------------------
The Trust's investment objective is capital appreciation and current income by
making investments through private placements in securities of small and medium
sized privately and publicly owned companies. Securities consist of subordinated
debt, preferred stock, or common stock combined with equity participation in
common stock or rights to acquire common stock. Investments are not held for
trading purposes.

The primary risk of the portfolio is derived from the underlying ability of
investee companies to satisfy debt obligations and their ability to maintain or
improve common equity values. Levels of interest rates are not expected to
impact the Trust's valuations, but could impact the capability of investee
companies to repay debt or create and maintain shareholder value.

As of March 31, 2006, the portfolio is valued at fair value, as determined by
the Independent Trustees ("Trustees"). In determining fair value, investments
are initially stated at cost until significant subsequent events and operating
trends require a change in valuation. Among the factors considered by the
Trustees in determining fair value of investments are the cost of the
investment, terms and liquidity of warrants, developments since the acquisition
of the investment, the sales price of recently issued securities, the financial
condition and operating results of the issuer, earnings trends and consistency
of operating cash flows, the long-term business potential of the issuer, the
quoted market price of securities with similar quality and yield that are
publicly traded, and other factors generally pertinent to the valuation of
investments. The Trustees relied on financial data of the portfolio companies
provided by the management of the portfolio companies. The Trust Advisor
maintains ongoing contact with management of the portfolio companies including
participation on their Boards of Directors and review of financial information.

There is no assurance that any investment made by the Trust will be repaid or
re-marketed. Accordingly, there is a risk of total loss of any investment made
by the Trust. At March 31, 2006, the amount at risk was $6,906,654 and consisted
of the following:

                                                    Cost            Valuation

     Debt securities and loans                 $   1,524,687      $   1,416,892

On September 1, 2003, the SBIC signed a loan agreement with the SBA. This debt
is carried on the balance sheet at its principal amount of $5,122,326 as of
March 31, 2006, which approximates the fair value of the loan.
