ECONOMIC OVERVIEW

DEAR KEMPER FUNDS SHAREHOLDER,

When an irresistible force such as the ebullient U.S. economy meets an immovable
object, such as a determined Federal Reserve Board, the old song is right:
Something's gotta give. One possibility -- the economy could slow down as the
Fed has ordered. Or, if market volatility becomes truly distressful, the Fed
could back off, as it has in the past. A third possibility is that neither the
Fed nor the economy will give way until it's too late, which could lead to a
recession. Recent evidence suggests, however, that the economy probably will
slow down as ordered. The Fed decided to leave rates unchanged at both its June
and August meetings, and in his testimony before Congress in late July, Fed
Chairman Alan Greenspan said he believes a slowdown has indeed arrived.

  Before explaining why we agree with the Fed that a slowdown is a good bet,
let's review how monetary policy works. Central bankers often sound like witch
doctors reading animal entrails, so it's understandable that many people are
confused about monetary policy. But monetary policy still works in the same way
it always has. First, it changes the price and availability of money. More
subtly, it alters people's perceptions about and confidence in the future,
thereby adjusting their willingness to take risks.

  The Fed only started raising interest rates a little over year ago, and it
takes at least that long for higher rates to impact borrowers. There are two
reasons. First, interest rates on many existing loans are fixed. And, a family
who has just selected a dream house isn't going walk away if mortgage rates rise
a notch. Similarly, a company that has just approved an expansion program won't
stop cold because the prime rate is higher. So it's foolish to think that
America's economy has become less interest-sensitive because the economy roared
through the first several months of this year. Americans are more in hock than
ever, so higher interest rates will hurt more than ever. The sharp drop in
housing starts and auto sales from their February peak is probably the first
sign that higher rates are biting. They will bite harder in coming months. We
look for both housing starts and vehicle sales to continue to drop and to be
lower in 2001 than in 2000.

  Confidence is harder to measure, but there are some early flutters of
weakness. It's true that consumers remain cheerily upbeat. But corporate bond
markets, the most sensitive barometer of business confidence and a vital source
of corporate funds, have been nervous. Investors are demanding a big premium
before they'll buy lower quality bonds, which means there's less new money for
companies to spend.

  So far, companies have been able to get around the bond market stinginess by
turning to their bankers. Banks lent businesses 9 percent more from January
through July of this year than they did during the first seven months of 1999.
But some banks are beginning to worry, too. Bank examiners have been questioning
the quality of loans and the level of reserves. In response, more bankers are
tightening lending standards and raising rates. This is a textbook case of how
tighter monetary policy eventually slows an economy.

  Aren't bond market and banker concerns overdone? As long as the economy keeps
growing at 3 percent or so, won't that guarantee such good profits that paying
the bills will be a cinch? Not necessarily. Profits are far more cyclical than
economic growth. Earnings actually fell during 1998, even though the economy
continued to roll. That was a global crisis, when foreign earnings fell sharply.
But take a look at the last "soft landing" during 1995. Revenue growth dipped
and pricing power fell, squeezing profits. The same thing is likely to happen
again in the coming slowdown -- and this time, tight labor markets could make it
even tougher for companies to control costs quickly. Assuming growth is between
2.5 percent and 3 percent by the end of 2001, we believe year-over-year profit
comparisons will have turned slightly negative.

  A profit slowdown when new lines of credit are hard to come by will take its
toll on capital spending. We expect growth in business outlays for buildings and
equipment to slip from over 12 percent this year to around 8 percent in 2001.
That's still quite robust, and the "high-tech imperative" is the reason why.
Executives believe that they have no option but to keep up with the
technological revolution that is transforming the world. The fact that high-tech
gear keeps getting cheaper year after year and also helps save on expensive
labor makes the decision to buy it easy. Indeed, unit sales of computers and
peripherals to businesses have sustained growth rates in excess of 40 percent
since 1995. And the rush is on to lay down the infrastructure for the next
generation of wireless communications. We estimate that the telecommunications
sector will see unit growth of more than 30 percent this year, double the
average growth of the past six years. It's hard even for

                                                                               3

                                                               ECONOMIC OVERVIEW

superstars to sustain these stratospheric compound growth rates forever, and we
do expect some moderation next year. However, high-tech orders continue to
ratchet upwards, and the shortage in semiconductors and other components has
persisted long enough to cause major players to announce huge capacity
additions.

  Another battle the Fed must win before it succeeds in slowing the economy is
bringing consumers to heel. Most families still feel better off than they were
last year and much richer than they were five years ago. That's a powerful
incentive to spend and enjoy. Indeed, total real consumption has been galloping
at a 5 percent rate or better since early 1998. But consumers are so important
to the economy that if they don't start spending less freely, there won't be a
slowdown. However, there is some evidence of moderation. Retailers have been
reporting sluggish summer sales, and the back-to-school season is getting off to
a slow start. This is music to the Fed's ears, because the policymakers would
like nothing better than to sit on the sidelines until well after the
Presidential election.

  So what will the slowdown look like? It will be concentrated in retail sales,
housing starts and job creation slowed (at least that's where it has surfaced so
far). However, strength in high tech orders and capital equipment production
probably will help keep the slowdown from becoming too abrupt. We expect about
3.5 percent growth in the second half. That would still produce a hearty 5
percent growth for full year 2000. During 2001, the full impact of the Fed's
earlier tightening will probably rein growth in to just 3 percent.

                             REVIEWS EACH OF THE PORTFOLIOS' RESULTS FOR THE 12
                             MONTHS ENDED JULY 31 IN THE CONTEXT OF THE FUND'S
                             LONG-TERM INVESTMENT STRATEGY.

Q     HOW DID THE KEMPER HORIZON FUND PORTFOLIOS PERFORM BETWEEN JULY 31, 1999,
AND JULY 31, 2000?

A     Each portfolio's absolute returns were weak but generally in line with the
performance of each portfolio's unmanaged composite benchmark. For the 12 months
ended July 31, 2000, Kemper Horizon 5 returned 0.37 percent; Kemper Horizon 10+
declined 0.94 percent and Kemper Horizon 20+ fell 3.85 percent. (All returns are
for Class A shares, unadjusted for sales charges.)

Q     TO WHAT DO YOU ATTRIBUTE THE PORTFOLIOS' RESULTS?

A     One of the largest factors impacting performance was the narrow market in
which we found ourselves for much of the year. Growth stocks, especially those
of larger companies, dominated the equity market by a large margin, a situation
that history has shown cannot continue indefinitely. As part of the fund's
long-term investment philosophy, we remained diversified across multiple asset
classes rather than bet on the market's short-term direction. In a challenging
market, the fund's diversification and disciplined investment process helped
reduce volatility to a level that was much less than a portfolio of domestic
stocks.

  The fund's valuation discipline also worked against us in the past year. When
picking stocks, we conduct quantitative analysis to evaluate several factors,
including a company's price-to-earnings and price-to-book ratios,
earnings-per-share growth rates and earnings predictability. Historically, these
parameters have been effective indicators of a stock's capital appreciation
potential. However, in the past year, amid emotional euphoria affecting certain
domestic growth stocks and initial public offerings, a systematic investment
strategy did not bear as much short-term fruit as we would have liked.

  During the fiscal period, we bought shares of companies that had significantly
higher earnings growth rates than those in our composite benchmark. These stocks
were also priced at a large discount relative to those in the benchmark. Neither
of these factors was rewarded in the marketplace. As such, the portfolios' low
price-to-earnings, price-to-book and price-to-revenue ratios relative to the
benchmark hurt performance.

Q     TECHNOLOGY STOCKS HAVE BEEN IN THE LIMELIGHT FOR THE PAST FEW YEARS. HOW
DID THIS SECTOR'S PERFORMANCE AND VOLATILITY PLAY OUT DURING FISCAL YEAR 2000?

A     From August 1999 until early March 2000, technology stocks rallied as
investors focused on non-cyclical growth companies that they believed would not
be hurt by the Federal Reserve Board's efforts to raise U.S. interest rates.
Biotechnology and Internet stocks were especially strong during this period.

PERFORMANCE UPDATE

Concentrated market leadership also translated into weak returns from other
sectors, especially cyclical and value stocks.

  However, as the Nasdaq Composite index crossed the 5000 mark for the first
time, it gradually became clear to many investors that prices of some technology
stocks had become excessive in relation to their earnings potential. Signs also
began emerging that the Federal Reserve Board's efforts to cool the U.S.
economy's torrid growth rate would affect demand for certain technology
products.

  The ides of March proved a critical turning point in market sentiment as
investors dethroned Internet stocks with questionable business plans in favor of
companies with sustainable earnings growth and selected "old economy" stocks.
Equity market leadership broadened out substantially beginning in April.

Q

      CAN YOU EXPLAIN THE DIFFERENCE IN PERFORMANCE AMONG KEMPER HORIZON 5,
KEMPER HORIZON 10+ AND KEMPER HORIZON 20+ FOR FISCAL 2000?

A
      By maintaining a 60 percent weighting in shorter-term fixed-income
securities in fiscal year 2000, Kemper Horizon 5 was in a good position to
preserve principal amid a rising interest-rate environment and a volatile
domestic equity market. During the period, the Federal Reserve Board increased
the federal funds rate -- the rate banks charge each other for overnight loans
-- to 6.50 percent, the highest rate in nine years.

  Kemper Horizon 10+ maintained a 40 percent weighting in a basket of
shorter-term fixed-income securities, while Kemper Horizon 20+ had a 20 percent
fixed-income weighting. Because it had the highest exposure to a broad mix of
domestic and international equities of the three portfolios, the results of
Kemper Horizon 20+ were the lowest for the fiscal period.

Q

      GIVEN THESE DYNAMIC MARKET CONDITIONS, WHAT STRATEGY DID YOU EMPLOY TO
KEEP THE FUND'S PORTFOLIO COMPOSITION IN LINE WITH ITS UNMANAGED BENCHMARK?

A
      By not attempting to guess that one asset class would outperform another,
we avoided much of the volatility associated with this past March's technology
sector setback. We attempted to derive the fund's returns from a relatively
steady asset-allocation mix. At the same time, we adjusted the mix slightly so
that each portfolio's composition remained in line with its respective composite
benchmark. This attempt to reduce so-called tracking errors is a portfolio
management technique that is often employed by institutional investors.

Q

      HOW DID SOME OF THE SECTORS IN WHICH YOU INVESTED HELP OR HURT
PERFORMANCE?

A
      Our positioning in financial services stocks hurt performance. This sector
was weighed down by concerns over rising interest rates and the outlook for
corporate earnings, which appeared to rely too heavily on investment gains.

  Our limited exposure to technology stocks also hurt performance. As we
mentioned earlier, this sector accounted for most of the stock market's gains
during the fiscal period.

  On a positive note, greater exposure to the health care sector helped us. We
saw a big turnaround in health care stocks in the first half of 2000, which we
attribute to investors' desire to own more defensive stocks.

Q

      WHAT WERE CONDITIONS LIKE IN THE INTERNATIONAL STOCK MARKET DURING THE 12
MONTHS ENDED JULY 31, 2000?

A
      International growth stocks delivered better performance than
international value stocks over the entire 12-month period. However, between
January and July, international value stocks outperformed growth stocks by
roughly 5 percent. Europe was one of the best-performing regions in the latter
half of our fiscal period. Japan, which had been charging ahead earlier in the
year, fell behind Europe during the annual period.

PERFORMANCE UPDATE

Q

      HOW DID THE INTERNATIONAL STOCK COMPONENT OF THE PORTFOLIOS PERFORM?

A
      The international stock portion of the portfolios delivered returns that
were fairly consistent with the benchmark MSCI EAFE index. This had a positive
impact on our performance.

  As we repositioned the portfolios in March to more closely track the fund's
unmanaged composite benchmark, we steered clear of making any large country
bets. The international component is very well diversified in more than 20
established countries, including Hong Kong, Japan, France, Germany, the United
Kingdom, the Netherlands and Italy. In fact, the same countries represented in
the MSCI EAFE index are represented in the three Horizon Fund portfolios.

Q

      EACH OF THE KEMPER HORIZON FUND PORTFOLIOS ALSO INVESTS IN FIXED-INCOME
SECURITIES WITH AN AVERAGE MATURITY OF LESS THAN THREE YEARS. HOW DID THIS PART
OF THE FUND FARE?

A
      The fixed-income component of the portfolios always consists of the
highest quality securities available. This includes U.S. Treasuries and federal
agency issues. The objective is to provide income and relative stability. We
strive to keep the average duration on the shorter side -- between one year and
three years. The shorter the duration, the less impact changes in interest rates
will have on the fund's bond component. Currently, the average duration is about
two and one-quarter years. We're comfortable with that duration given recent
signs that the Fed may be close to finishing raising interest rates in the near
term.

Q

      WHAT DO YOU THINK IS THE BIGGEST ADVANTAGE OF DIVERSIFYING THE KEMPER
HORIZON FUND PORTFOLIOS ACROSS ASSET CLASSES?

A
      Without a doubt, diversification gives us the ability to better manage
risk. We can gauge portfolio risk using a statistical measure called "standard
deviation." The higher the numeric value, the greater the risk. For year ended
July 31, 2000, Kemper Horizon 20+ had a standard deviation of 10.47, compared
with 15.00 for the unmanaged Standard & Poor's 500 index. That means that the
most aggressive Horizon Fund portfolio had a risk profile that was 30 percent
lower than that of a portfolio of large-cap domestic equities. Horizon 10+'s
standard deviation for the same period was 7.29, while Horizon 5 had a standard
deviation of 5.09.

Q

      WHAT IS YOUR OUTLOOK FOR THE MARKETS FOR THE MONTHS AHEAD?

A
      While we believe that international stocks will be the dominant-performing
asset category over the next 12 months, we aren't putting all of our eggs in
that basket. We are mindful of the fact that many Horizon Fund investors use the
fund as a vehicle for their retirement nest egg, and we will continue to
structure the portfolios in ways that we believe can provide the potential for
attractive results over the long term.

TERMS TO KNOW

CAPITALIZATION/MARKET CAPITALIZATION A measure of the current market value of a
company's publicly traded stock, as determined by multiplying the current share
price by the number of shares outstanding.

CYCLICAL COMPANY A business whose operations have a high degree of economic
sensitivity. At the start of an economic expansion, cyclical stocks may rise
quickly; as an economy slows, stocks of cyclical companies may fall quickly.
Cyclical stocks include industrial machinery, basic materials, automobiles,
construction and certain retailers.

DURATION A measure of the interest-rate sensitivity of a portfolio,
incorporating time to maturity and coupon size. The longer a portfolio's
duration, the greater its sensitivity to interest-rate changes.

FEDERAL FUNDS RATE The interest rate banks charge each other for overnight loans
that are needed to meet reserve requirements. The Federal funds rate is often
considered the most sensitive indicator of the direction of interest rates.

GROWTH COMPANY A company enjoying a strong, long-term expansion of sales or
market share. Stocks of growth companies generally trade at prices based on a
multiple of the company's future growth in sales, cash flow or earnings rather
than its historical record of earnings or measures of value such as dividend
yield.

INVERTED YIELD CURVE A market phenomenon in which intermediate-term bonds
(securities with one-to 10-year maturities) have higher income potential and
current yields than long-term bonds (securities with 10-to 30-year maturities).
Historically, an inverted yield curve has occurred during a period of rising
short-term interest rates and been viewed as an indicator of a future economic
slowdown.

TRACKING ERROR A measure of the degree to which a portfolio's asset allocation
strategy and performance deviate from the composition and performance of an
unmanaged benchmark index or composite of unmanaged indices.

PAST PERFORMANCE IS NOT A GUARANTEE OF
FUTURE RESULTS. INVESTMENT RETURNS AND
PRINCIPAL VALUE WILL FLUCTUATE SO THAT
SHARES, WHEN REDEEMED, MAY BE WORTH MORE
OR LESS THAN ORIGINAL COST.

 *AVERAGE ANNUAL TOTAL RETURN AND TOTAL
  RETURN MEASURE NET INVESTMENT INCOME
  AND CAPITAL GAIN OR LOSS FROM
  PORTFOLIO INVESTMENTS OVER THE PERIODS
  SPECIFIED, ASSUMING REINVESTMENT OF
  ALL DIVIDENDS AND, WHERE INDICATED,
  ADJUSTMENT FOR THE MAXIMUM SALES
  CHARGE. THE MAXIMUM SALES CHARGE FOR
  CLASS A SHARES IS 5.75%. FOR CLASS B
  SHARES THE MAXIMUM CONTINGENT DEFERRED
  SALES CHARGE (CDSC) IS 4%. CLASS C
  SHARES HAVE NO SALES CHARGE
  ADJUSTMENT, BUT REDEMPTIONS WITHIN ONE
  YEAR OF PURCHASE MAY BE SUBJECT TO A
  CONTINGENT DEFERRED SALES CHARGE OF
  1%. SHARE CLASSES INVEST IN THE SAME
  UNDERLYING PORTFOLIO. AVERAGE ANNUAL
  TOTAL RETURN REFLECTS ANNUALIZED
  CHANGE, WHILE TOTAL RETURN REFLECTS
  AGGREGATE CHANGE. DURING THE PERIODS
  NOTED, SECURITIES PRICES FLUCTUATED.

     SIGNIFICANT
     ACCOUNTING POLICIES     Kemper Horizon Fund (the "Fund") is registered
                             under the Investment Company Act of 1940, as
                             amended (the "1940 Act"), as an open-end,
                             diversified management investment company organized
                             as a Massachusetts business trust. The Fund
                             consists of three investment portfolios
                             ("Portfolios") designed for investors with
                             different investment objectives. The three
                             Portfolios are Kemper Horizon 20+, Kemper Horizon
                             10+ and Kemper Horizon 5. Each Portfolio offers
                             multiple classes of shares. Class A shares are
                             offered to investors subject to an initial sales
                             charge. Class B shares are offered without an
                             initial sales charge but are subject to higher
                             ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions. Class B shares automatically
                             convert to Class A shares six years after issuance.
                             Class C shares are offered without an initial sales
                             charge but are subject to higher ongoing expenses
                             than Class A shares and a contingent deferred sales
                             charge payable upon certain redemptions within one
                             year of purchase. Class C shares do not convert
                             into another class. Class I shares are offered to a
                             limited group of investors, are not subject to
                             initial or contingent deferred sales charges and
                             have lower ongoing expenses than other classes.

                             Investment income, realized and unrealized gains
                             and losses, and certain fund-level expenses and
                             expense reductions, if any, are borne pro rata on
                             the basis of relative net assets by the holders of
                             all classes of shares except that each class bears
                             certain expenses unique to that class such as
                             distribution services, shareholder services,
                             administrative services and certain other class
                             specific expenses. Differences in class expenses
                             may result in payment of different per share
                             dividends by class. All shares of each Portfolio
                             have equal rights with respect to voting subject to
                             class specific arrangements.

                             Each Portfolio's financial statements are prepared
                             in accordance with accounting principles generally
                             accepted in the United States which require the use
                             of management estimates. The policies described
                             below are followed consistently by the Fund in the
                             preparation of its financial statements.

                             SECURITY VALUATION. Investments are stated at value
                             determined as of the close of regular trading on
                             the New York Stock Exchange. Securities which are
                             traded on U.S. or foreign stock exchanges are
                             valued at the most recent sale price reported on
                             the exchange on which the security is traded most
                             extensively. If no sale occurred, the security is
                             then valued at the calculated mean between the most
                             recent bid and asked quotations. If there are no
                             such bid and asked quotations, the most recent bid
                             quotation is used. Securities quoted on the Nasdaq
                             Stock Market ("Nasdaq"), for which there have been
                             sales, are valued at the most recent sale price
                             reported. If there are no such sales, the value is
                             the most recent bid quotation. Securities which are
                             not quoted on Nasdaq but are traded in another
                             over-the-counter market are valued at the most
                             recent sale price, or if no sale occurred, at the
                             calculated mean between the most recent bid and
                             asked quotations on such market. If there are no
                             such bid and asked quotations, the most recent bid
                             quotation shall be used.

                             Portfolio debt securities purchased with an
                             original maturity greater than sixty days are
                             valued by pricing agents approved by the officers
                             of the Fund, whose quotations reflect
                             broker/dealer-supplied valuations and electronic
                             data processing techniques. If the pricing agents
                             are unable to provide such quotations, the most
                             recent bid quotation supplied by a bona fide market
                             maker shall be used. Money market instruments
                             purchased with an original maturity of sixty days
                             or less are valued at amortized cost.

                             All other securities are valued at their fair value
                             as determined in good faith by the Valuation
                             Committee of the Board of Trustees.

                             FOREIGN CURRENCY TRANSLATIONS. The books and
                             records of each Portfolio are maintained in U.S.
                             dollars. Investment securities and other assets and
                             liabilities denominated in a foreign currency are
                             translated into U.S. dollars at the prevailing
                             exchange rates at period end. Purchases and sales
                             of investment securities, income and expenses are
                             translated into U.S. dollars at the prevailing
                             exchange rates on the respective dates of the
                             transactions.

                             Net realized and unrealized gains and losses on
                             foreign currency transactions represent net gains
                             and losses between trade and settlement dates on
                             securities transactions, the disposition of forward
                             foreign currency exchange contracts and foreign
                             currencies, and the difference between the amount
                             of net investment income accrued and the U.S.
                             dollar amount actually received. That portion of
                             both realized and unrealized gains and losses on
                             investments that results from fluctuations in
                             foreign currency exchange rates is not separately
                             disclosed but is included with net realized and
                             unrealized gains and losses on investment
                             securities.

                             REPURCHASE AGREEMENTS. The Portfolios may enter
                             into repurchase agreements with certain banks and
                             broker/dealers whereby each Portfolio, through its
                             custodian or sub-custodian bank, receives delivery
                             of the underlying securities, the amount of which
                             at the time of purchase and each subsequent
                             business day is required to be maintained at such a
                             level that the market value is equal to at least
                             the principal amount of the repurchase price plus
                             accrued interest.

                             FEDERAL INCOME TAXES. Each Portfolio's policy is to
                             comply with the requirements of the Internal
                             Revenue Code, as amended, which are applicable to
                             regulated investment companies and to distribute
                             all of its taxable income to its shareholders.
                             Accordingly, each Portfolio paid no federal income
                             taxes and no federal income tax provision was
                             required.

                             DISTRIBUTION OF INCOME AND GAINS. Distributions of
                             net investment income, if any, are made as follows:
                             annually for Kemper Horizon 20+ , semiannually for
                             Kemper Horizon 10+ and quarterly for Kemper Horizon
                             5. Net realized gains from investment transactions,
                             in excess of available capital loss carryforwards,
                             would be taxable to each Portfolio if not
                             distributed, and, therefore, will be distributed to
                             shareholders at least annually.

                             The timing and characterization of certain income
                             and capital gains distributions are determined
                             annually in accordance with federal tax regulations
                             which may differ from generally accepted accounting
                             principles. As a result, net investment income
                             (loss) and net realized gain (loss) on investment
                             transactions for a reporting period may differ
                             significantly from distributions during such
                             period. Accordingly, each Portfolio may
                             periodically make reclassifications among certain
                             of its capital accounts without impacting the net
                             asset value of each Portfolio.

REPORT OF INDEPENDENT AUDITORS

THE BOARD OF TRUSTEES AND SHAREHOLDERS

KEMPER HORIZON FUND

  We have audited the accompanying statements of assets and liabilities,
including the portfolios of investments, of Kemper Horizon 20+ Portfolio, Kemper
Horizon 10+ Portfolio and Kemper Horizon 5 Portfolio, comprising Kemper Horizon
Fund (the Funds) as of July 31, 2000, and the related statements of operations
for the year then ended, and changes in net assets for each of the two years in
the period then ended, and the financial highlights for each of the fiscal
periods since 1996. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

  We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audits to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of investments
owned as of July 31, 2000, by correspondence with the custodian. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the portfolios comprising Kemper Horizon Fund at July 31, 2000, the results
of their operations for the year then ended, the changes in their net assets for
each of the two years in the period then ended, and the financial highlights for
each of the fiscal periods since 1996 in conformity with accounting principles
generally accepted in the United States.

                                                               ERNST & YOUNG LLP
