                   CIRCUIT RESEARCH LABS INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (unaudited)


1.   The Consolidated Condensed Financial Statements included herein have been
prepared by Circuit Research Labs, Inc. ("CRL" or the "Company"), pursuant to
the rules and regulations of the Securities and Exchange Commission. The
Consolidated Condensed Balance Sheet as of March 31, 2002 and the Consolidated
Condensed Statements of Operations for the three months ended March 31, 2002 and
2001 and the Consolidated Condensed Statements of Cash Flows for the three
months ended March 31, 2002 and 2001 have been prepared without audit.

     Certain information and note disclosures normally included in financial
statements prepared in accordance with accounting principles generally accepted
in the United States of America have been condensed or omitted pursuant to such
rules and regulations, although the Company believes that the disclosures are
adequate to make the information presented not misleading. It is suggested that
these Consolidated Condensed Financial Statements be read in conjunction with
the consolidated financial statements and notes thereto included in the
Company's Annual Report on Form 10-KSB for the year ended December 31, 2001.

     In the opinion of management, the Consolidated Condensed Financial
Statements for the unaudited interim periods presented herein include all
adjustments, consisting only of normal recurring adjustments, necessary to
present a fair statement of the results of operations for such interim periods.
Net operating results for any interim period may not be comparable to the same
interim period in previous years, nor necessarily indicative of the results that
may be expected for the full year.

2.   Significant Accounting Policies are as follows:

a.   Net loss per share

     In calculating earnings per share for the three months ended March 31, 2002
the effects of 1,000,000 shares relating to options to purchase common stock and
1,708,158 shares relating to warrants were not used for computing diluted
earnings per share because the result would be anti-dilutive. For the three
months ended March 31, 2001 the options and warrants to purchase 1,026,500 and
1,708,158 shares respectively, of common stock were not used in computing
diluted earnings because the result would be anti-dilutive. Statement of
Financial Accounting Standards ("SFAS") No. 128, "Earnings per Share"
establishes standards for computing and presenting earnings per share. It also
requires the dual presentation of basic and diluted earnings per share on the
face of the statement of operations. Earnings per share is calculated as
follows:

b.   New accounting pronouncements

     In July 2001, the Financial Accounting Standards Board (FASB) issued SFAS
Nos. 141 and 142 ("SFAS 141" and "SFAS 142"), "Business Combinations" and
"Goodwill and Other Intangible Assets."  SFAS 141 replaces APB Opinion No. 16
and eliminates pooling-of-interests accounting prospectively.  It also provides
guidance on purchase accounting related to the recognition of intangible assets
and accounting for negative goodwill.  SFAS 142 changes the accounting for
goodwill from an amortization method to an impairment-only approach.  Under SFAS
142, goodwill will be tested at least annually and whenever events or
circumstances occur indicating that goodwill might be impaired.  SFAS 141 and
SFAS 142 are effective for all business combinations initiated after
June 30, 2001.

     Upon adoption of SFAS 142, amortization of goodwill recorded for business
combinations consummated prior to July 1, 2001 will cease, and intangible assets
acquired prior to July 1, 2001 that do not meet the criteria for recognition
under SFAS 141 will be reclassified to goodwill.  Companies are required to
adopt SFAS 142 for fiscal years beginning after December 15, 2001.  The Company
adopted SFAS 142 on January 1, 2002.  SFAS 142 requires that goodwill be tested
for impairment, at least annually, and shall not be amortized.  The goodwill
impairment test is a two-step process.  The first step compares the fair value
of a reporting unit with its carrying amount.  If the fair value exceeds the
carrying amount, goodwill of the reporting unit is considered not impaired and
no further testing is necessary.  If the fair value is less than the carrying
value, the second step must be performed to determine the amount of the
impairment.  The second step compares the implied fair value of the reporting
unit goodwill with the carrying amount of that goodwill.  If the carrying amount
of the reporting unit goodwill exceeds the implied fair value of that goodwill,
an impairment loss is recognized in an amount equal to that excess.  Any loss
resulting from the transitional impairment test will be reflected as a change in
accounting principle.

     The Company is in the process of determining the estimated fair value of
each reporting unit with a view to determining whether the goodwill value has
been impaired under these new rules.  In accordance with the transition
provisions of SFAS 142, this evaluation will be completed by June 30, 2002.
Management has not yet completed this assessment.

     At the time that an acquisition is made, the Company records each asset
acquired and each liability assumed at its estimated fair value, which estimate
is subject to future adjustment when appraisals or other valuation data are
obtained.  The excess of (i) the total consideration paid for the acquired
assets over (ii) the fair value of the assets acquired, less liabilities
assumed, is recorded as goodwill.  As of March 31, 2002, the Company has no
identifiable intangible assets with definite lives.


                                        9

     At December 31, 2001 and March 31, 2002, the Company reported $5,734,180
and $7,476,008, respectively, of net goodwill on its consolidated balance
sheets.  At both dates, both amounts included $5,719,142 for the acquisition of
Orban, Inc. and $15,038 for the acquisition of Avocet Instruments, Inc.  In
addition, the March 31, 2002 figure includes $1,741,828 for the acquisition of
Dialog4 System Engineering GmbH.  The following table presents the impact of
goodwill amortization to the quarter ended March 31, 2001 net loss and loss per
share:
                                          Net Loss    Basic EPS   Diluted EPS
                                          ---------   ---------   -----------
     Reported Net Loss                    $(42,172)   $(0.02)     $(0.02)
     Add back: Goodwill amortization       263,960      0.12        0.12

     In August 2001, the FASB issued Statement of Financial Accounting Standards
No. 143 ("SFAS 143"), "Accounting for Obligations Associated with the Retirement
of Long-Lived Assets."  SFAS 143 establishes accounting standards for the
recognition and measurement of an asset retirement obligation and its associated
asset cost.  It also provides accounting guidance for legal obligations
associated with the retirement of tangible long-lived assets.  SFAS 143 is
effective in fiscal years beginning after June 15, 2002, with early adoption
permitted.  The Company plans to adopt SFAS 143 effective January 1, 2003.  The
Company has not determined the effect of adopting SFAS 143 on its consolidated
results of operations or financial position.

     In October 2001, the FASB issued Statement of Financial Accounting
Standards No. 144 ("SFAS 144"),  "Accounting for the Impairment or Disposal of
Long-Lived Assets."  SFAS 144 establishes a single accounting model for the
impairment or disposal of long-lived assets, including discontinued operations.
SFAS 144 superseded Statement of Financial Accounting Standards No. 121,
"Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed Of," and APB Opinion No. 30, "Reporting the Results of Operations -
Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary,
Unusual and Infrequently Occurring Events and Transactions."  The provisions of
SFAS 144 are effective in fiscal years beginning after December 15, 2001, with
early adoption permitted, and in general are to be applied prospectively.  The
Company adopted SFAS 144 effective January 1, 2002 and has not yet determined
the impact, if any, this standard will have on its consolidated results of
operations and financial position.


c.   Reclassifications

     Certain reclassifications have been made to the 2001 consolidated condensed
financial statements to conform to the classifications used in 2002 and have no
effect on previously reported net loss.

                                                    ==========

      On May 31, 2000, CRL Systems, Inc. and Harman Acquisition Corp. (formerly
known as Orban, Inc.) entered into a Credit Agreement to establish the terms and
conditions of the $8,500,000 loan from Harman to CRL Systems.  The agreement was
executed in conjunction with the Asset Sale Agreement between Harman and CRL
Systems, Inc.  The loan is evidenced by two promissory notes, the Senior
Subordinated Tranche A Note (the "Tranche A Note") and the Senior Subordinated
Tranche B Note (the "Tranche B Note").  The Tranche A Note, in the amount of
$5,000,000, originally bore interest at 8 percent per annum and required
quarterly principal payments beginning March 31, 2001, with a balloon payment
of $3,000,000 due on March 31, 2003.  The Tranche B Note, in the amount of
$3,500,000, originally bore interest at 8 percent per annum for the period from
June 1, 2000 to July 31, 2000 and 10 percent per annum from August 1, 2000 up to
its September 30, 2000 maturity date.  The notes are collateralized by, among
other things, all receivables, inventory and equipment, investment property,
including CRL's capital stock in CRL Systems, and intellectual property of CRL
and CRL Systems, as defined in the Guarantee and Collateral Agreement.  In
addition, all proceeds of debt or equity or sales of assets are to be first
applied to the remaining balance due on the notes, with the exception of
proceeds from the sale of stock to the Company's President and Chief Executive
Officer, Charles Jayson Brentlinger, pursuant to a Stock Purchase Agreement
between the Company and Mr. Brentlinger which was entered into prior to the date
of the Orban acquisition.

     The Company received several payment extensions on the Tranche A and B
notes.  First, in exchange for $150,000 cash and an increase in the interest
rates to 12 percent per annum for both the Tranche A and Tranche B notes, Harman
extended the maturity date of the Tranche B note to November 30, 2000.  The
maturity date of the Tranche B note was subsequently extended several additional
times without fees or other significant changes to the original terms of the
note and is now due in full on April 30, 2002.  Also, the first principal
payment on the Tranche A note of $250,000, originally due March 31, 2001, was
extended to September 30, 2001 with the remaining quarterly principal payments
deferred until April 30, 2002.  Interest only payments are payable monthly for
both notes.  The Asset Sale Agreement between CRL Systems and Harman contained a
provision allowing Harman to rescind the transaction if, as of November 30,
2000, CRL Systems had not paid in full the $3.5 million short-term

note.  If Harman had exercised its option to rescind the agreement, it would
have been required to return $9,250,000 of the purchase price to CRL Systems,
with the difference due to Harman as liquidating damages.  Harman's option to
rescind the agreement has since expired.

     On October 1, 2001, the Company and Harman entered into an Amendment to the
Credit Agreement (the "Amended Credit Agreement") under which both the
short-term and the long-term promissory notes were amended and restated.  Under
the Amended Credit Agreement, both promissory notes were converted to demand
notes payable upon the demand of Harman.  Interest is paid monthly at 12 percent
per annum.  Additionally, $1,250,000 is due April 30, 2002, unless Harman
demands payment at an earlier date.

     On May 1, 2002, the Registrant entered into a Second Amendment to Credit
Agreement with Harman under which the long- and short-term demand notes were
amended and restated to remove the requirement for quarterly payments on the
long-term note and to extend the maturity dates for the notes to December 31,
2003, unless Harman demands payment at an earlier date.  Interest only payments
remain payable monthly at 12 percent per annum for both notes and are also due
on demand.

     In consideration for arranging the purchase financing of Orban, the Company
incurred fees of $97,500 to a stockholder, the total of which was included in
the current portion of long-term debt at December 31, 2000.  The note was due on
August 14, 2001 after being extended from its prior due date of May 14, 2001 and
accrues interest of 7.5 percent per annum.  On August 10, 2001, the note was
converted to equity at the market price of $1.05 per share.

     In connection with the acquisition of the assets of Orban, the Company
issued $205,000 in long-term debt to a stockholder in consideration for his role
in such acquisition.  The note bears interest at 7.5 percent per annum, with
principal and interest due monthly beginning August 1, 2000 for four years.
Based on a verbal agreement with the note holder, the Company made payments in
2001 sufficient for interest and some principal.  Subsequently on November 12,
2001, the Company amended the agreement whereby the Company and the stockholder
agreed to defer the payments to January 2002 with interest accruing at the rate
of 7.5% per annum. As of March 31, 2002, the Company has made partial payments
on the accrued interest.

     On May 30, 2000, the Company mortgaged its office building and
manufacturing facility in Tempe, Arizona for $335,000 in order to raise part of
the purchase price payable in connection with its acquisition of Orban.  The
mortgage note bore interest at 15.25 percent per annum, payable monthly.  The
full principal balance of the mortgage note was originally due November 30,
2000, but the maturity date was extended to December 31, 2000.  Prior to that
date, the Company refinanced the unpaid balance and entered into two new
mortgage agreements for $300,000 and $62,000, respectively.  The notes bear
interest at 11.75 percent per annum and 14.75 percent per annum, respectively.
Principal and interest payments are payable monthly for both notes commencing in
February 2001, using a 12-year amortization period and requiring a balloon
payment in February 2006.

     On June 12, 2000, the Company entered into an unsecured promissory note for
$68,387 from an employee, which bears interest at 12 percent per annum.  The
unpaid principal and interest that was due September 12, 2000 was extended to
June 30, 2001 without payment of a fee.  In order to further extend the note,
the Company agreed to make 12 monthly installments of principal and interest
over a one-year period commencing September 1, 2001.  The Company did not pay a
fee in connection with this extension.  As part of the agreement, the note
continues to bear interest at 12 percent per annum, but will be compounded
monthly.


                                       12


     On May 31, 2001, CRL acquired the assets of Avocet Instruments, Inc., for
$82,980 plus other costs of $3,350.  The acquisition has been accounted for as
an asset purchase.  The excess of the total acquisition costs over the fair
value of the assets acquired was $16,195.  In conjunction with the Asset Sale
Agreement between the Company and Avocet Instruments, Inc. and Eric B. Lane
(Sellers), the Company and the Sellers entered into a Credit Agreement to
establish the terms and conditions of the purchase price.  The loan is evidenced
by an agreement whereby the Company paid the Sellers $25,000 interest-free, paid
$5,000 on the Closing Date, and $5,000 in each of the following four months.
Thereafter, the balance ($57,980) is being paid in monthly installments of
$1,200, including interest at the rate of five percent per annum for 54 months.

     In the fourth quarter of fiscal year 2001, the Company converted various
payables into notes payable and long-term debt totaling $179,903, of which
$90,076 was short-term debt and $89,827 was long-term debt. As of March 31, 2002
the balance of the notes payable and long-term debt have been reduced to
$108,556, of which $103,917 is current and $4,639 is non-current.


5.   ACQUISITION OF DIALOG4

     On January 18, 2002, the Company acquired the assets of Dialog4 System
Engineering GmbH ("Dialog4").  Dialog4, a German corporation based in
Ludwigsburg, Germany, is a worldwide leader in ISO/MPEG, audio, ISDN, satellite
transmission, networking and storage.  Dialog4 has been designing and
manufacturing equipment for the codec market for over ten years.  Its products,
available in Europe since 1993, include the MusicTaxi codec for encoding and
decoding audio and data over TCP/IP on the Internet, ISDN and satellite.

     The Company purchased the assets of Dialog4 pursuant to an Asset Sale and
Purchase Agreement for $2 million, comprised of 1,250,000 shares of restricted
common stock, valued at $1.00 per share, and $750,000 cash to be paid at a later
date either by the Company from its working capital or by the Company's
President and Chief Executive Officer, Charles Jayson Brentlinger.  On April 8,
2002, the Company executed an amendment to the Asset Sale and Purchase Agreement
with Dialog4.  The amended agreement extends the term of the Company's payments
to Dialog4 over twenty months while reducing the amount of the monthly payment
installments to $37,500 plus interest on the remaining principal balance at a
rate of 10 percent per annum.  The monthly installments of principal and
interest are due and payable on the twentieth day of each month commencing
April 20, 2002.

The following table shows the fair values of assets and liabilities recorded for
the acquisition of Dialog4 System Engineering GmbH:

     Inventories                                      $228,000
     Property and equipment, net                        65,000
     Goodwill                                        1,742,000

     Share consideration paid                       $1,250,000
     Debt issued                                       750,000
     Cash consideration paid                            35,000
     Debt assumed                                            0


                                       13

     In connection with the acquisition, Berthold Burkhardtsmaier, Dialog4's
managing director, has become the Company's Vice President of European
Operations and has been appointed to its board of directors.

ITEM  2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

     The following discussion of our financial condition and results of
operations should be read together with the financial statements and the
accompanying notes included elsewhere in this report.  This discussion contains
statements about future events, expectations, risks and uncertainties that
constitute forward-looking statements, as do discussions elsewhere in this
report. Forward-looking statements are based on management's beliefs,
assumptions and expectations of our future economic performance, taking into
account the information currently available to management.  These statements are
not statements of historical fact.  Forward-looking statements involve risks and
uncertainties that may cause actual results, performance or financial condition
to differ materially from the expectations of future results, performance or
financial condition we express or imply in any forward-looking statements.  The
words "believe," "may," "will," "should," "anticipate," "estimate," "expect,"
"intend," "objective," "seek," "strive" or similar words, or the negative of
these words, identify forward-looking statements. Our actual results may differ
materially from those anticipated in those forward-looking statements as a
result of certain factors, including, but not limited to, those described below
under this Item 2, "Management's Discussion and Analysis or Plan of Operation -
Risk Factors."  We qualify any forward-looking statements entirely by these
cautionary factors.


RECENT DEVELOPMENTS

     Effective May 1, 2002, we entered into a Second Amendment to Credit
Agreement with Harman Acquisition Corp. (formerly known as Orban, Inc.) under
which the long- and short-term demand notes payable to Harman were amended and
restated to remove the requirement for quarterly payments on the long-term note
and to extend the maturity dates for the notes to December 31, 2003, unless
Harman demands payment at an earlier date.  Interest only payments remain
payable monthly at 12 percent per annum for both notes and are also due on
demand.


OVERVIEW

     We develop, manufacture and market high-quality electronic audio
processing, transmission encoding and noise reduction equipment for the
worldwide radio, television, cable, Internet and professional audio markets.
In recent periods, we have acquired the assets of other companies within our
industry or in related industries into which we desire to expand.  On May 31,
2000, we acquired the assets of Orban, Inc., a producer of audio editing and
processing equipment.  On May 31, 2001, we acquired the assets of Avocet
Instruments, Inc., a supplier of quality audio receivers and coders for the
television and post-production industry.  On January 18, 2002, we acquired the
assets of Dialog4 System Engineering GmbH, a worldwide leader in ISO/MPEG,
audio, ISDN, satellite transmission, networking and storage.  The results of our
acquisition of Dialog4 are reflected in the financial statements included in
this report.

     We are still in the process of integrating the operations of our CRL and
Orban divisions, including integration of our financial accounting and
management information systems.  Once this integration is complete, we expect to
benefit from cost savings produced by combined research and development,
marketing, sales and administration, manufacturing efficiencies and
cross-selling opportunities.  Our recent acquisition of the Dialog4 product line
has led to the establishment of our new Orban Europe division offices in
Ludwigsburg, Germany.  We now face the challenge of integrating our financial
accounting and management information systems with those of Dialog4 as well as
the challenge of overcoming obstacles produced as a result of different
corporate cultures and different accounting and reporting regulations.  We will
also face new risks arising from foreign currency fluctuations.


                                       15

     We incurred losses of $2,046,640 and $2,258,121 during the years ended
December 31, 2001 and 2000, respectively.  Our deteriorating financial results
and reduced liquidity caused us to renegotiate our $8.5 million loan agreement
with Harman.  Under the terms of the new agreement, Harman can demand at any
time that we immediately pay in full the outstanding balance.  Should this
happen, we would immediately be forced to file for protection under Chapter 11
of the United States Bankruptcy Code.  Our inability to pay the $8.5 million
debt to Harman should payment be demanded, our difficulties in meeting our
financing needs and our negative working capital position have resulted in our
independent public accountants adding a going concern emphasis paragraph to
their report (set forth in our Form 10-KSB for the year ended December 31, 2001)
by including a statement that such factors raise substantial doubt about our
ability to continue as a going concern.  In addition to our efforts to reduce
costs and increase sales, we are currently seeking sources of long-term
financing.  However, the inclusion of a going concern emphasis paragraph
generally makes it more difficult to obtain trade credit, insurance or
additional capital through public or private debt or equity financings.

(1)  EBITDA is defined as earnings before interest, taxes, depreciation and
amortization.  Companies and analysts do not calculate this measure in the same
fashion and, as a result, the measure presented may not be comparable to
similarly titled measures reported by other companies.  EBITDA should be
considered in addition to, not as a substitute for or superior to, operating
income, cash flows or other measures of financial performance prepared in
accordance with accounting principles generally accepted in the United States.
This information is not intended to assist investors in an analysis of our
liquidity because there are a number of uses of cash that are excluded from the
EBITDA measurement, as reported in our statement of cash flows.  Rather,
investors may wish to use this information as one of a number of points of
comparison between our reported net loss in 2002 and 2001.  None of the funds
depicted by the EBITDA measure above were available for management's
discretionary use.


                                       16

THREE MONTHS ENDED MARCH 31, 2002 COMPARED TO THE THREE MONTHS ENDED
MARCH 31, 2001

      Net Sales.  Net sales during the three months ended March 31, 2002 were
$3.0 million compared to $3.9 million during the comparable period in 2001
reflecting a decrease of 23%.  The decrease in net sales was primarily
attributable to a decreased in demand for our product. Our Orban division
reported net sales of $2.8 million for the three months ended March 31, 2002 as
compared to $3.6 million for the same period in 2001. This decrease was
primarily a result of a decreased demand from our single largest customer by
66%. Our CRL division reported net sales of $172,000 for the three months ended
March 31, 2002 as compared to $350,000 for the same period in 2001, representing
a decrease of 51%.  This decrease was the result of decreased demand from one
customer overseas.  We are uncertain whether this decreased demand will continue
for our CRL products, but generally, we expect continued stable demand across
its product lines in 2002.  Orban Europe reported net sales of $327,000.

     Gross Profit.   Gross profit was 47% of net sales for the first quarter
ended March 31, 2002 compared to 55% for the same period in 2001. The 8%
decrease in gross profit is primarily due to decreased production while
maintaining the same fixed overhead costs and the acquisition of the Dialog4
assets. Gross profit for that division was 38%. The lower percentage as a
division is primarily due to the discounting of sales price for the introduction
of Orban Europe products into the market under the Orban name.  The Orban Europe
division plans to focus on increasing the gross profit.

     Selling, General and Administrative.  Selling, general and administrative
expenses ("SG&A") for the three months ended March 31, 2002 were $1,126,000, a
decrease of 10%  compared to $1,253,000 reported the first quarter of 2001. As a
percentage of net revenue, SG&A increased from 32% for the three months ended
March 31, 2001 to 38% for the same period in 2002.  The increase in SG&A expense
is due in part to the variable component of SG&A (discounts and other domestic
and international sales and marketing expenses) associated with the increase in
revenues following our acquisition of the Dialog4 assets. The fixed component of
SG&A has also increased due to the additional personnel in sales, marketing,
administration and cost related to operating the Orban Europe office following
the January 18, 2002 acquisition.

     Research and Development.   Research and development expense was $315,000
for the three months ended March 31, 2002, a decrease of 3% compared to $324,000
for the same period in 2001. The decrease resulted from the reduction of fees to
outside consultants.

     Other (Income) Expense.   Other expense, net for the three months ended
March 31, 2002 was $279,000 of which $255,000 represents interest paid to Harman
International Industries, Inc. in connection with the seller carry-back loan
that financed a portion of our purchase price for the Orban assets.  Other
expense, net for the three months ended March 31, 2001 was $273,000, of which
$255,000 represented interest and fees paid to Harman. Interest expense was
$283,000 1for the three months ended March 31, 2002, a 2% increase over $277,000
reported for the same period in 2001. The increase represents the interest
expense associated with the Second Amendment to the Asset purchase of Dialog4.

     Operationally, we are reporting a $33,000 loss for the three months ended
March 31, 2002, before interest, taxes, depreciation and amortization (EBITDA)
which represents approximately 1% of the total net sales in 2002 as compared to
2001 in which we reported a $574,000 profit before interest, taxes, depreciation
and amortization (EBITDA) representing 15% of net sales.  The decrease in EBITDA
is primarily due to the reduction in sales.


                                       17

     Net Loss.  Net loss was $402,664 for the three months ended March 31, 2002
compared to $42,172 for the same period in 2001.  Excluding the impact of the
non-cash items, we would have reported a net loss $248,084 for the three months
ended March 31, 2002 compared to a positive net income of $296,535 for the same
period in 2001.

     Non-cash expense items for the three months ended March 31, 2002 were as
     follows:

                   $0     Increase in inventory reserve
                 (267)    Decrease in provision for uncollectible accounts
                    0     Amortization of intangible
               50,000     Stock compensation
               86,156     Depreciation
             --------
             $135,889     Total (representing 38% of the net loss for the year)
             ========

     Non-cash expense items for the three months ended March 31, 2001 were as
     follows:

              $74,747     Depreciation
              263,960     Amortization of intangible
             $338,707     Total (representing 803% of the net loss for the year)

     The decrease in amortization from 2001 to 2002 reflected in the charts
above resulted from our adoption of Statement of Financial Accounting Standards
No. 142 effective January 1, 2002.


LIQUIDITY AND CAPITAL RESOURCES

     We had negative net working capital of approximately $7.1 million at
March 31, 2002, and the ratio of current assets to current liabilities was
...37 to 1. At March 31, 2001, we had net positive working capital of
approximately $2.5 million and a current ratio of 2.08 to 1.  The decrease in
working capital resulted from the conversion to demand notes of the $3.5
million short-term note and the $5 million long-term notes payable to Harman.
The notes are payable on December 31, 2003 or as specified in the Second
Amendment to Credit Agreement that we entered into with Harman effective
May 1, 2002.

     Our substantial obligation to Harman may have important consequences for
us, including the following:

     * Our ability to continue as a going concern will depend in part on whether
       Harman demands payment on the $8.5 million debt, or any portion thereof;
     * A significant portion of our cash flow from operations will be dedicated
       to servicing our debt obligations and will not be available for other
       business purposes;
     * The terms and conditions of our indebtedness limit our flexibility in
       planning for and reacting to changes in our business, and in making
       strategic acquisitions;
     * Our ability to obtain additional financing in the future for working
       capital, capital expenditures and other purposes may be substantially
       impaired; and
     * Our substantial leverage may make us more vulnerable to economic
       downturns and competitive pressures.

     Our ability to meet our debt service obligations and reduce our total
indebtedness to Harman depends in part on our future operating performance.  Our
future operating performance will depend on


                                       18

our ability to expand our business operations by growing our core audio
processing business, expanding our product offerings and penetrating new and
emerging markets, which we anticipate will require additional financing.  In
addition, our future operating performance will depend on economic, competitive,
regulatory and other factors affecting our business that are largely beyond our
control.  If we are unable to expand our business operations as planned, we may
not be able to service our outstanding indebtedness to Harman.

     On January 18, 2002, with Harman's consent, we acquired the assets of
Dialog4 System Engineering GmbH.  We purchased the assets of Dialog4 pursuant to
an Asset Sale and Purchase Agreement for $2 million, comprised of 1,250,000
shares of our common stock, valued at $1.00 per share, and $750,000 cash to be
paid at a later date either by us from our working capital or by our President
and Chief Executive Officer, Charles Jayson Brentlinger.  On April 8, 2002, we
executed an amendment to the Asset Sale and Purchase Agreement with Dialog4.
The amended agreement extends the term of our payments to Dialog4 over twenty
months while reducing the amount of the monthly payment installments to $37,500
plus interest on the remaining principal balance at a rate of 10 percent per
annum.  The monthly installments of principal and interest are due and payable
on the twentieth day of each month commencing April 20, 2002.

     Working capital generated from 2002 operations will be used to service our
contractual obligations and commercial commitments, excluding our obligations to
Harman.  Any excess working capital generated from 2002 operations will be
applied to expand our business operations.  The terms of the Harman debt
restrict our ability to obtain financing for these types of expansion
expenditures, as well as financing for other purposes.  Accordingly, our ability
to expand will primarily depend on our ability to generate sufficient working
capital from operations.  We will closely monitor our working capital in 2002 as
we evaluate any expenditures related to expansion.

     Accounts receivable were $1,157,000 at March 31, 2002 compared to $641,000
at December 31, 2001 representing a net increase of $516,000 or 80%.  The
increase is primarily due to an increase in sales for the quarter ended
March 31, 2002 compared to the quarter ended December 31, 2001.

     Total inventories were $2,663,000 at March 31, 2002 compared to total
inventories of $2,828,000 at December 31, 2001.  The value of inventory
decreased $165,000, or 6%, due primarily to the reduction of raw materials and
work in process.

     For the year ending December 31, 2002, our principal working capital
requirements will be the payment of normal recurring operating costs.
Management believes that these requirements can be met from the operating cash
flows.

     On May 31, 2000, our wholly owned subsidiary, CRL Systems, Inc., acquired
the assets of Orban, Inc., a wholly owned subsidiary of Harman International
Industries, Inc.  The total stated purchase price was $10.5 million, of which
$2 million was paid in cash and the balance of which was paid by means of a
combination of short-term and long-term promissory notes that we issued to
Harman.  On October 1, 2001, we entered into an Amendment to Credit Agreement
with Harman under which both the long-term and the short-term notes were
converted to demand notes payable on the demand of Harman or, if no demand is
sooner made, on the dates and in the amounts specified in the Amended Credit
Agreement.  Effective May 1, 2002, we entered into a Second Amendment to Credit
Agreement with Harman under which both demand notes were amended and restated to
remove the requirement for quarterly payments on the long-term note and to
extend the maturity dates for the notes to December 31, 2003, unless Harman
demands payment at an earlier date.  Interest only payments remain payable
monthly at 12 percent per annum for both notes and are also due on demand.



                                       19

     Approximately $9,563,000 of our total indebtedness is due and payable by
December 31, 2003, unless with respect to the $8,500,000 due Harman, payment is
demanded at an earlier date.  Our President, Mr. Charles Jayson Brentlinger, has
committed to exercise his stock options, if necessary, to satisfy a portion of
the Company's debt payment requirements if operating cash flows are inadequate
to retire the debt.  If Mr. Brentlinger exercised all of his options to purchase
shares of our common stock, we would realize gross proceeds of approximately
$1,250,000.  We are actively pursuing opportunities to raise additional capital
through a private equity placement of our common stock, asset based lending, or
a combination of the two.  We cannot offer any assurances that we will be able
to attract additional capital or that additional financing, if obtained, will be
sufficient to meet our current obligations.  If we cannot meet our current
obligations, our ability to continue as a going concern will be jeopardized.

     On June 12, 2000, we borrowed $68,387 from an employee to assist us in the
purchase of the assets of Orban.  The unsecured promissory note evidencing the
debt bears interest at 12 percent per annum.  The note was originally due
September 12, 2000 but was extended to June 30, 2001 without payment of a fee.
In order to further extend the note, we agreed to make 12 monthly installment
payments of principal and interest over a one-year period commencing
September 1, 2001.  We did not pay a fee in connection with this extension.  As
part of the agreement, the note continues to bear interest at 12 percent per
annum, but is compounded monthly.  As of March 31, 2002, we had paid a total of
$27,576 on the note and the remaining unpaid balance was $40,811.

     Management believes that the required $37,500 due to Dialog4 each month can
be met from the operating cash flows generated from the Dialog4 line of
products.  The required payments may slow our ability to ramp up our European
operations.


RISK FACTORS

     You should carefully consider the following risk factors and all other
information contained in this report in evaluating us and our business.  You
should also keep these risk factors in mind when you read and consider the
forward-looking statements in this report and other reports we file with the
SEC.  The risks and uncertainties described below are not the only ones facing
us.  Additional risks and uncertainties that we are unaware of, or that we
currently deem less material, also may become important factors that affect us.


AS A RESULT OF OUR LARGE OUTSTANDING DEBT OBLIGATIONS, WE HAVE SIGNIFICANT
ONGOING DEBT SERVICE REQUIREMENTS WHICH MAY ADVERSELY AFFECT OUR FINANCIAL AND
OPERATING FLEXIBILITY.

     On May 31, 2000, we acquired the assets of Orban, a wholly-owned subsidiary
of Harman International Industries, Inc.  Including the $250,000 previously paid
to Harman as non-refundable deposits in 1999, the total stated purchase price
was $10.5 million, of which $2 million was paid in cash and the balance of which
was paid by means of a combination of short-term and long-term promissory notes
that we issued to Harman.  As of September 30, 2001, our total indebtedness was
approximately $8.5 million.  Effective October 1, 2001, this indebtedness was
converted to demand notes payable on the demand of Harman or, if no demand is
sooner made, on the dates and in the amounts set forth in the amended Credit
Agreement that we entered into with Harman.  Our substantial leverage may have
important consequences for us, including the following:

     *    our ability to continue as a going concern will depend in
          part on whether Harman demands payment on the $8.5 million debt,
          or any portion thereof;


                                       20


     *    a significant portion of our cash flow from operations will
          be dedicated to servicing our debt obligations and will not be
          available for other business purposes;
     *    the terms and conditions of our indebtedness limit our
          flexibility in planning for and reacting to changes in our
          business, and in making strategic acquisitions;
     *    our ability to obtain additional financing in the future for
          working capital, capital expenditures, and other purposes may be
          substantially impaired; and
     *    our substantial leverage may make us more vulnerable to
          economic downturns and competitive pressures.

     Our ability to meet our debt service obligations and reduce our total
indebtedness to Harman depends in part on our future operating performance.  Our
future operating performance will depend on our ability to expand our business
operations by growing our core audio processing business, expanding our product
offerings and penetrating new and emerging markets, which we anticipate will
require additional financing.  In addition, our future operating performance
will depend on economic, competitive, regulatory and other factors affecting our
business that are beyond our control. If we are unable to expand our business
operations as planned, we may not be able to service our outstanding
indebtedness to Harman.


THE EXISTENCE OF AN UNQUALIFIED OPINION CONTAINING A GOING CONCERN EMPHASIS
PARAGRAPH MAY MAKE IT MORE DIFFICULT FOR US TO OBTAIN CREDIT OR ADDITIONAL
CAPITAL AND MAY JEOPARDIZE OUR RELATIONSHIP WITH EXISTING AND NEW CUSTOMERS.

     Our inability to pay the $8.5 million debt to Harman should payment be
demanded, our difficulties in meeting our financing needs and our negative
working capital position created by the demand notes have resulted in our
independent public accountants adding a going concern emphasis paragraph in
their report by including a statement that such factors raise substantial doubt
about our ability to continue as a going concern. The inclusion of a going
concern emphasis paragraph generally makes it more difficult to obtain trade
credit, insurance or additional capital through public or private debt or equity
financings.  We may also find it more difficult to maintain existing customer
relationships and to initiate new customer relationships.


WE WILL NEED ADDITIONAL DEBT OR EQUITY TO SERVICE THE DEBT PAYABLE AS A RESULT
OF OUR ACQUISITION OF ORBAN, AND WE MAY NOT BE ABLE TO OBTAIN THIS FINANCING ON
ACCEPTABLE TERMS.

     Upon our acquisition of the assets of Orban, we issued a $3.5 million
short-term note and a $5 million long-term note payable to Harman.  Effective
October 1, 2001, both of these notes were converted to demand notes payable on
the demand of Harman or, if no demand is sooner made, on the dates and in the
amounts set forth in the amended Credit Agreement that we entered into with
Harman.  Our ability to service this debt will depend on our ability to obtain
either additional debt or equity financing, or a combination thereof.  We cannot
be sure, however, that we will be able to obtain the necessary debt or equity
financing on acceptable terms.  Also, additional debt financing or the sale of
additional equity securities may cause the market price of our common stock to
decline.  If we are unable to obtain additional debt or equity financing on
acceptable terms, we may have to negotiate further restructuring of the debt
with Harman. If Harman is unwilling to restructure the debt, we may default on
the debt and our ability to continue as a going concern would be jeopardized.


OUR ABILITY TO OBTAIN AN OUTSIDE LINE OF CREDIT IS SUBJECT TO THE APPROVAL OF
OUR CURRENT CREDITORS AND, IF SUCH APPROVAL IS WITHHELD, OUR ABILITY TO COMPETE
EFFECTIVELY IN OUR INDUSTRY COULD BE JEOPARDIZED.


                                       21

     In connection with our acquisition of Orban, we entered into a Credit
Agreement with Harman.  Under the terms of the Credit Agreement, we are bound by
certain covenants that prevent us from obtaining additional credit facilities
without the prior written approval of Harman.  This limitation on our ability to
obtain additional outside lines of credit may curtail our ability to make
strategic acquisitions and to conduct research and development.  This in turn
could jeopardize our competitive position within our industry.


FOREIGN CURRENCY FLUCTUATIONS COULD ADVERSELY AFFECT OUR RESULTS OF OPERATIONS.

     On January 18, 2002, we acquired the assets of Dialog4 System Engineering
GmbH.  Our acquisition of this new product line has led to the establishment of
our new Orban Europe offices in Ludwigsburg, Germany.  Transactions and expenses
of our Orban Europe operations will be conducted in Euros which will expose us
to market risks related to foreign currency exchange rate fluctuations that
could adversely affect our operating results. For instance, a strengthening of
the U.S. dollar against the Euro could reduce the amount of cash and income we
receive and recognize from Orban Europe.  Furthermore, it is likely that for
accounting purposes we will recognize foreign currency gains or losses arising
from our operations in Europe on weighted average rates of exchange in the
period incurred and translate assets and liabilities of these operations into
U.S. dollars based on year-end foreign currency exchange rates, both of which
are subject to currency fluctuations between the U.S. dollar and the Euro.  As
foreign exchange rates vary, our results from operations and profitability may
be adversely affected.

     We expect to derive approximately 13% of our total revenues from our Orban
Europe operations.  This percentage may increase in future years as we further
develop and expand our operations in Europe.  We cannot predict the effects of
exchange rate fluctuations on our operating results.  We do not currently intend
to engage in foreign currency exchange hedging transactions to manage our
foreign currency exposure.  If and when we do engage in foreign currency
exchange hedging transactions, we cannot assure you that our strategies will
adequately protect our operating results from the effects of exchange rate
fluctuations.


WE HAVE A LIMITED OPERATING HISTORY ON WHICH TO BASE AN EVALUATION OF OUR
COMBINED OPERATIONS WITH ORBAN AND OUR PROSPECTS FOR THE FUTURE.

     We commenced our combined operations with Orban on May 31, 2000.
Accordingly, we have a limited operating history on which an evaluation of our
combined operations with Orban can be based. Our prospects must be considered in
light of the risks, expenses, difficulties and uncertainties frequently
encountered by companies in the early stages of integration, such as:

     *    the difficulty of integrating the operations, technologies,
          personnel and cultures of our companies;
     *    the potential disruption of the ongoing business of our
          companies;
     *    the distraction of management of our companies from ongoing
          business concerns;
     *    potential unknown liabilities associated with the merger of
          our companies; and
     *    the potential disruption of our employee base.

     We cannot guarantee that any or all of the above risks, expenses,
difficulties and uncertainties will not occur as a result of our integration of
the Orban operations.  Nor can we guarantee that our integration with Orban will
be achieved successfully or as rapidly as we would like.


                                       22

OUR FUTURE SUCCESS IS DEPENDENT ON OUR SUCCESSFUL INTEGRATION OF THE ORBAN
OPERATIONS INTO OUR OWN.

     We are in the process of integrating the operations of Orban with our
existing operations in order to achieve economies of scale, manufacturing and
marketing efficiencies, reduced operational expenses and cross-selling
opportunities.  Although the combination of our operations with those of Orban
has produced substantial synergies, nevertheless this combination is ongoing and
continues to present significant management challenges.  We cannot assure you
that this integration, and the synergies expected to result from that
integration, will be achieved to the extent initially anticipated.  If
management is unable to completely and successfully integrate our operations
with those of Orban, we will not fully realize the benefits of integration noted
above, and our business, results of operations and financial condition could be
adversely affected.


WE SERVE A MARKET IN WHICH THERE ARE A LIMITED NUMBER OF CUSTOMERS AND OUR
FINANCIAL WELL-BEING IS DIRECTLY TIED TO THE FINANCIAL HEALTH OF THESE
CUSTOMERS.

     In recent years, the radio and television industry in the United States has
experienced a great deal of consolidation of ownership.  As a result, several
corporations each now own a substantial number of radio and television stations.
These corporations are the largest purchasers of our audio processing and
post-production equipment.  Moreover, a significant amount of our revenue is
derived from audio processing replacement orders that come from these customers.
Our financial stability and well-being is thus directly tied to the financial
health of these customers.  If these customers experience financial difficulty,
regardless of the cause, they may delay, reduce or cancel orders for new audio
processing or post-production equipment.  If this occurs, our results of
operations could decline and we could experience difficulty in servicing our
debt obligations.


WE MUST ADAPT TO RAPID TECHNOLOGICAL CHANGE AND INCREASED COMPETITION IF WE ARE
GOING TO BE ABLE TO COMPETE EFFECTIVELY IN OUR INDUSTRY.

     While audio processing has been and will continue to be our core business,
we are using our existing technologies to enter the emerging markets of digital
audio broadcasting, cable television and Internet-related audio delivery.  These
markets are characterized by rapid technological change and require a
significant commitment of capital and human resources.  We intend to engage
continually in research and development activities so that we can improve our
current products and develop new products.  However, our significant debt
obligations may limit the amount of resources, both capital and human, that we
can commit to research and development.  This could jeopardize the success and
reception of our products in these emerging markets. In addition, because of the
rapid pace of change and the intense competition that characterizes these
markets, our products may become unmarketable or obsolete by a competitor's more
rapid introduction to the marketplace.


WE MAY NOT BE ABLE TO RETAIN OUR EXISTING PERSONNEL OR HIRE AND RETAIN THE
ADDITIONAL PERSONNEL THAT WE NEED TO SUSTAIN AND GROW OUR BUSINESS.

     Our future success will depend on our ability to attract, retain and
motivate employees with the necessary skills and expertise required by our
business.  Competition for employees who possess the technical expertise to
develop and manufacture our products is intense.  A shortage in available
skilled labor could require us to increase our wages and benefits to attract
and retain enough employees.  An increase in our labor costs, or our inability
to attract, retain and motivate employees, would likely harm our growth plans
and may adversely affect our business and results of operations.


                                      23

WE DEPEND ON A NUMBER OF VENDORS TO SUPPLY US WITH COMPONENT PARTS THAT ARE
NECESSARY TO THE PRODUCTION OF OUR AUDIO PROCESSING AND POST-PRODUCTION
EQUIPMENT.

     We rely on certain vendors to provide component parts for use in the
manufacturing of our audio processing and post-production equipment.  As
technology improves, some of these parts have become obsolete and vendors have
discontinued their production of such parts.  When this occurs, we must either
obtain these necessary parts from alternative sources, or design around these
parts so that we are able to continue producing our audio processing and
post-production equipment.  If any of the component parts that we require become
unavailable and we are not able to design around these parts, we may not be able
to offer some of our products and our sales revenues may decline.


OUR PRESIDENT, CHIEF EXECUTIVE OFFICER AND CHAIRMAN OF THE BOARD EXERCISES
SIGNIFICANT CONTROL OVER US.

     Charles J. Brentlinger, our President, Chief Executive Officer and Chairman
of the Board, currently owns 820,318 shares of our common stock and holds
options to purchase approximately 1,365,005 additional shares.  Based on a total
of 3,706,880 shares of our common stock issued and outstanding as of March 31,
2002, if Mr. Brentlinger exercises all of his options he will own of record and
beneficially approximately 43.1% of our issued and outstanding shares.  This
means that Mr. Brentlinger exercises, and will continue to exercise, significant
control over the business and affairs of our company.  Mr. Brentlinger's
exercise of this control may, in certain circumstances, deter or delay a merger,
tender offers, other possible takeover attempts or changes in our management
which may be favored by some or all of our minority shareholders.


WE DEPEND ON A FEW KEY MANAGEMENT PERSONS.

     We are substantially dependent on the personal efforts and abilities of
Charles Jayson Brentlinger, our Chairman, President and Chief Executive Officer,
and Robert Orban, our Vice President and Chief Engineer.  The loss of either of
these officers or our other key management persons could harm our business and
prospects for growth.  As a result, we have obtained key man life insurance
policies on the lives of each of these officers.  We also have employment
agreements with each of these officers which are more fully described elsewhere
in this report.


THE LOCATION OF OUR ORBAN DIVISION SUBJECTS US TO A NUMBER OF RISKS THAT ARE
BEYOND OUR CONTROL WHICH COULD RESULT IN PRODUCTION INTERRUPTIONS.

     Our business depends on the efficient and uninterrupted production of our
audio processing equipment and other products. Our Orban division is currently
located in San Leandro, California, and we expect to maintain our operations at
this facility for the foreseeable future.  While we have taken precautions
against production interruptions, interruptions could nevertheless result from
natural disasters such as earthquakes, fires or floods.  In addition, the power
shortages which occur in California from time to time have resulted in planned
and unplanned power outages and increased energy costs which we may not be able
to pass on to our customers.  Power outages, which last beyond our backup and
alternative power arrangements, could harm our customers and our business.
Finally, our location in the Silicon Valley corridor of California subjects us
to increased operating costs and labor shortages which could adversely affect
our production capabilities and result in reduced revenues.


THE MARKET PRICE OF OUR COMMON STOCK HAS BEEN VOLATILE AND THE VALUE OF YOUR
INVESTMENT MAY DECLINE.


                                       24

     The volatility of the market price of our common stock may cause wide
fluctuations in the price of our common stock on the OTC Bulletin Board.  The
market price of our common stock is likely to be affected by:

     *    changes in general conditions in the economy or the
          financial markets;
     *    variations in our quarterly operating results;
     *    changes in financial estimates by securities analysts;
     *    other developments affecting us, our industry, customers or
          competitors;
     *    the operating and stock price performance of companies that
          investors deem comparable to us; and
     *    the number of shares available for resale in the public
          markets under applicable securities laws.


THE LIQUIDITY OF OUR COMMON STOCK COULD BE RESTRICTED BECAUSE OUR COMMON STOCK
FALLS WITHIN THE DEFINITION OF A PENNY STOCK.

     Under the rules and regulations of the Securities and Exchange Commission
(SEC), as long as the trading price of our common stock on the OTC Bulletin
Board is less than $5 per share, our common stock will come within the
definition of a "penny stock."  On April 1, 2002, the last sale price of our
common stock on the OTC Bulletin Board was $1.33 per share.  Generally speaking,
the definition of a "penny stock" does not include stock that is traded on
Nasdaq or on a national securities exchange.  Since our common stock is traded
on the OTC Bulletin Board, rather than on Nasdaq or a national securities
exchange, our common stock falls within the definition of a  "penny stock"
while it is trading below $5 per share.  As a result, the trading of our common
stock is subject to certain "penny stock" rules and regulations.

     The SEC rules and regulations require that broker-dealers, prior to
effecting any transaction in a penny stock, satisfy certain disclosure and
procedural requirements with respect to the prospective customer.  These
requirements include delivery to the customer of an SEC-prepared risk disclosure
schedule explaining the nature and risks of the penny stock market, disclosure
to the customer of the commissions payable to both the broker-dealer and any
other salesperson in connection with the transaction, and disclosure to the
customer of the current quotations for the stock to be purchased.  In addition,
if the broker-dealer is the sole market maker, it must disclose this fact and
the broker-dealer's presumed control over the market. Finally, prior to
effecting any penny stock transaction, broker-dealers must make individualized
written suitability determinations and obtain a written agreement from customers
verifying the terms of the transaction.  Subsequent to any sale of penny stock,
broker-dealers must send monthly statements disclosing recent price information
for the penny stock held in the customer's account and certain other information
relating to the limited market in penny stocks. These rules, regulations and
procedural requirements may restrict the ability of broker-dealers to sell our
common stock or discourage them from doing so.  As a result, purchasers may find
it more difficult to dispose of, or to obtain accurate quotations for, our
common stock.


BECAUSE OUR SUCCESS DEPENDS IN PART ON OUR ABILITY TO PROTECT OUR INTELLECTUAL
PROPERTY, INFRINGEMENT ON OUR PROPRIETARY RIGHTS COULD LEAD TO COSTLY LITIGATION
AND DECREASED REVENUES.

     Our copyrights, patents, trademarks, trade secrets and similar intellectual
property are critical to our success.  To establish and protect our proprietary
rights, we rely on a combination of copyright, trademark, patent and trade
secret laws, confidentiality and non-disclosure agreements and contractual
provisions with employees and third parties, and license agreements with
consultants, vendors and


                                       25

customers. Despite such protections, there can be no
assurance that these steps will be adequate, that we will be able to secure
trademark registrations for all of our marks in the United States or other
countries or that third parties will not infringe upon or misappropriate our
copyrights, patents, trademarks and similar proprietary rights.  In addition,
effective copyright, patent and trademark protection may be unenforceable or
limited in certain countries.  In the future, litigation may be necessary to
enforce and protect our trade secrets, copyrights, patents and other
intellectual property rights.  We may also be subject to litigation to defend
against claims of infringement of the rights of others or to determine the scope
and validity of the intellectual property rights of others.  Any such litigation
could cause us to incur substantial expenses and would adversely affect our
financial condition.

                           PART II - OTHER INFORMATION


ITEM 2.  CHANGES IN SECURITIES

RECENT SALES OF UNREGISTERED SECURITIES

     Set forth below is information concerning sales of our common stock (or
transactions deemed to be sales) during the quarter ended March 31, 2002 that
were not registered under the Securities Act of 1933, as amended (the "Act").
All such securities are restricted securities and the certificates bear
restrictive legends.

     On January 18, 2002, our wholly owned subsidiary, CRL Systems, Inc. doing
business as Orban, Inc., acquired the assets of Dialog4 System Engineering GmbH,
a worldwide leader in ISO/MPEG, audio, ISDN, satellite transmission, networking
and storage.  Orban/CRL purchased the assets of Dialog4 pursuant to an Asset
Sale and Purchase Agreement for $2 million, comprised of 1,250,000 shares of our
common stock, valued at $1.00 per share, and $750,000 cash.  In connection with
this transaction, we relied on the exemption from registration under
Section 4(2) of the Act.
