Dear Fellow Shareholders:

             THIS MAY BE OUR LAST WORD ON A BROADENING STOCK MARKET

     In our last two reports, we discussed the possibility that the market would
broaden to include better performance for more stocks. As most investors are
aware, in the last few years the bull market has been led by a handful of large
growth stocks resulting in capitalization-weighted indexes, like the S&P 500,
providing the best performance. In fact, about the only way to beat this index
was to own a portfolio concentrated in the few leaders or concentrated in
technology stocks. It's not much of an overstatement to say that during the bull
market in these few stocks, a bear market was in place for many more stocks.
While providing reasonable absolute returns, many investments, especially
value-oriented portfolios across all capitalization ranges, have had difficulty
keeping up.

     In our May report, we observed a change that began in April, with very good
performance for value and cyclical stocks as well as small- and mid-cap stocks.
Since April, small- and mid-cap growth stocks have continued to perform well,
but cyclical and value stocks have fallen back. The initial move toward a
broader market has dropped the S&P 500 from the front to the middle of the pack
for year-to-date performance in the list of indexes that includes a variety of
investment styles. Some excellent stock selection and the broadening environment
led to improved performance for several of our funds, especially the Westcore
MIDCO Growth Fund.

                         AN EVOLUTION NOT A REVOLUTION

     History provides many examples of unhappy endings for markets where
performance was concentrated in a few names with high valuations. A notable
example was the "nifty fifty" era of 1972-73, which was followed by a major
market decline (revolution) in 1974, especially in the leaders of those years.
We believe it is possible for the market to broaden without requiring a
revolution or correction in the leaders. We foresee the possibility for an
evolution. The leaders are, by and large, great businesses with outstanding
financial characteristics by almost any measure, such as growth and return on
investment, and are generally superior to the prior "nifty fifty".

     Nonetheless, the performance of the current leaders has been driven by
one-part strong fundamentals and two-parts higher valuations. The high
valuations are justified by low inflation and the companies' above average
growth. A challenging question is that if a company's absolute multiple has
tripled, and its relative multiple has doubled, what are the chances of this
repeating? In our view, not high, even though we see nothing on the horizon to
change the favorable economic environment of productivity-led growth with
moderate inflation. We expect an evolution where valuations are generally
maintained for current leaders, and the market broadens to include a variety of
other companies.

     The Westcore Fund Family is well positioned with research-driven equity
funds, investing in either small-, mid- or large-cap companies and providing
exposure to either growth or value stocks. Westcore also offers fixed-income
funds and a double tax-exempt fund for Colorado investors. Westcore's diverse
offering of funds provides investors an opportunity to take advantage of a
broadening market, and to meet multiple investment objectives.

                        NEW FUNDS INCREASE OPPORTUNITIES

     In October, we introduced the Westcore Small-Cap Growth Fund and the
Westcore Select Fund, and in December, we began the Westcore International
Frontier Fund. Each of the funds will be managed by our research-intensive
investment approach and provide investors exposure to three interesting market
sectors. Westcore Small-Cap Growth Fund will take advantage of the small-cap
growth sector, which continually

                                        1
<PAGE>   3

provides opportunities to discover and invest in small, exciting companies with
excellent growth potential. Westcore Select Fund will be a more concentrated
portfolio with the flexibility to move across all capitalization and style
ranges to find the best current investments. Westcore International Frontier
Fund will invest in international, small-cap growth companies, which provide the
same benefits as U.S. small-cap growth companies and is a market sector that we
believe is under-exploited.

     As we look forward to a prosperous new year, we thank you for your
continued investment in Westcore.

                                            Sincerely

                               MANAGER'S OVERVIEW
                      SEMI-ANNUAL REPORT NOVEMBER 30, 1999

WESTCORE MIDCO GROWTH FUND

FUND OBJECTIVE: Seeks to maximize long-term capital appreciation by investing
primarily in medium-sized growth companies.

Q.   HOW DID THE FUND PERFORM?

A.   Our portfolio did well. It was up 23.05% for the first six months compared
     to the Russell Midcap Growth Index, which was up 20.83%.

Q.   TO WHAT DO YOU ATTRIBUTE THIS OUTPERFORMANCE OF THE INDEX?

A.   Technology stocks account for most of our gains. I used to think of
     technology as an industry, but today it is a broad economic sector with
     many industries such as semiconductors, networking equipment, software,
     computer hardware, wireless equipment and the "dot.com" companies.

Q.   HAS YOUR PORTFOLIO COMPOSITION CHANGED?

A.   At the moment, companies in the technology sector make up 50% of our
     portfolio. The remaining 50% of the portfolio is comprised primarily of
     stocks in Healthcare, Retail and Media.

     Today there is another way to think about the portfolio structure. Every
     stock can be classified as a participant in the "new economy" or the "old
     economy." New economy stocks are building the digital communication system
     and/or using the Internet to do business in different ways. An example of a
     new economy stock is JDS Uniphase, a stock we have owned for several years.
     It is the leading supplier of passive and active components needed for
     moving data by glass fiber. We do own some old economy stocks. An example
     would be Family Dollar Stores, a small "brick and mortar" retailer of
     low-priced goods.

Q.   TECHNOLOGY COMPANIES HAVE BEEN WIDELY TALKED ABOUT AS HAVING HIGH
     VALUATIONS. WHAT IS YOUR TAKE ON THAT?

A.   Valuation of new economy companies should certainly be at the top of
     investors' minds. The valuation multiples are being valued as high as 30
     times next year's revenues -- and the companies earn little or no money.
     Instead, they are trying to become the "gorillas" in their respective
     spaces, postponing profitability to obtain market dominance. They hope to
     earn money after they have established their quasi monopoly.

     These are the types of companies that provide much of our
     performance -- and for that matter, the performance of most money managers
     in the last year. It creates a large challenge for my analytical team and
     me. At some point, these valuations will compress, but nobody knows when
     this will really be.

     This compression in valuation could also happen quickly. Of course, a quick
     drop in valuation might be a buying opportunity and not a sign this period
     of super-high valuations has ended.

Q.   WHAT IS YOUR OUTLOOK?

A.   Overall positive. We acknowledge we can't identify where each stock will
     hit the top of its run, but we are looking hard for signs of business
     slowing. We have a well-diversified portfolio including some old economy
     stocks selling at reasonable multiples. I think it's important to remind
     our shareholders to control risk within their own portfolios by
     diversifying their mutual fund investments by owning several with different
     styles that fulfill their objectives.

WESTCORE GROWTH AND INCOME FUND

FUND OBJECTIVE: Seeks to maximize long-term total return by investing in equity
securities selected for their growth potential and income-producing abilities.

Q.   HOW DID THE FUND PERFORM?

A.   For the six-months ended November 30, 1999, Westcore Growth and Income
     Fund's total return was 19.59%. In comparison, the Standard & Poor's 500
     Index returned 7.36%.

Q.   WHAT FACTORS AFFECTED THE FUND'S PERFORMANCE?

A.   We made two key strategic decisions. First, we increased the exposure to
     technology stocks. Second, we increased our exposure to medium-sized growth
     companies. Towards the end of 1998, we had more large-cap stocks because
     that was the area of the market that was expected to do best. As 1999
     progressed, we determined that mid-cap stocks were more attractively
     valued.

     As it turned out, we were "two for two," because tech stocks were very
     strong, and medium-sized companies generally outperformed large-cap stocks.
     These two tactical decisions improved the Fund's performance over the past
     six months.

Q.   HOW DO YOU SELECT STOCKS?

A.   We look at companies with strong earnings growth, exciting products and
     quality management -- companies that can participate in a rapidly growing
     area of the economy. Our research analysts visit many companies and meet
     with management to assess the likelihood that a company can meet its goals
     and flourish in their competitive environment.

Q.   WHAT STOCKS PERFORMED WELL DURING THE PERIOD?

A.   Cisco Systems, a dominant player in the growth of the Internet, rose 64%
     during the six-month period. Cisco Systems is a leading producer of
     routers, which is technology that, for example, directs e-mail to a given
     computer. A second example is Nokia, a leading manufacturer of cellular
     telephones, which rose 94%. Nokia continues to develop new products with
     increased functionality.

Q.   SINCE TECHNOLOGY HAS DONE SO WELL, WHY NOT FOCUS EVEN MORE THERE?

A.   Part of a portfolio manager's job is to manage risk as well as return.
     Currently, more than 35% of the portfolio is invested in technology, which
     is significantly more than the S&P 500 Index. And while it's true that
     technology has had a great run, it would be imprudent to boost the
     allocation higher. At some point, we know that technology's dominance is
     going to subside. Over the past few years, we've seen technology have its
     ups and downs. To balance risk and reward, we want to have a major exposure
     to technology, but not go overboard.

Q.   WHAT WOULD YOU SAY HAS BEEN A DISAPPOINTMENT?

A.   Drug stocks have been disappointing. For instance, Merck has been adversely
     affected by concerns that Medicare prescription benefits would be expanded.
     In effect, that would give the government the power to dictate prices to
     the drug companies. This has lead to lowered expectations for Merck's
     earnings growth. However, we believe that the pharmaceutical industry is
     ultimately a solution to rising health care costs, not the problem. It's
     certainly cheaper to buy prescription antibiotics than to spend a week in
     the hospital fighting an infection. Therefore, we are maintaining exposure
     to this sector and remain optimistic about this industry's long-term growth
     prospects.

Q.   WHAT IS YOUR CURRENT OUTLOOK?

A.   The current environment of low inflation and strong economic growth remains
     a positive for stocks. The Federal Reserve Board has raised interest rates
     to stave off inflation -- but a recession is not in sight.

              SEMI-ANNUAL REPORT NOVEMBER 30, 1999 -- (CONTINUED)

Because so many groups of stocks have not participated in the latest rally,
there is bound to be some rotation out of technology and into these other
groups. Since there is no way of knowing when this will happen, we think our
approach of having a diversified portfolio bodes well for the Fund.

This Fund participates in the Initial Public Offering (IPO) market, and a
significant portion of the fund's returns have been attributable to its
investment in IPOs, which in turn have had a magnified impact due to the fund's
relatively small asset base. As the Fund's assets continue to grow, it will be
increasingly less likely to experience substantially similar performance by
investing in IPOs.

WESTCORE SMALL-CAP GROWTH FUND

FUND OBJECTIVE: Seeks long-term growth of capital primarily through investments
in small companies with growth potential.

Q.   SINCE THE FUND IS NEW AS OF OCTOBER 1, 1999, LET'S FIRST DISCUSS YOUR
     INVESTMENT OBJECTIVE AND STRATEGY.

A.   Our goal is long-term capital appreciation by investing in companies with
     market capitalizations between $100 million and $2.5 billion. A growth
     company would be one with 20% annual growth in sales and earnings -- and,
     preferably, positive momentum. If it's an Internet company with great sales
     growth but losses, then we would need to see those losses narrow as the
     company drives towards profitability. For liquidity purposes, we prefer
     companies with trading volume of at least 125,000 shares per day.

Q.   HOW WOULD YOU DESCRIBE THE PORTFOLIO CURRENTLY?

A.   The portfolio currently includes 27 stocks, so it is fairly focused. Our
     goal is to own the best companies in the best industries, and we do not
     attempt to match industry weightings with an index or benchmark, which in
     our case is the Russell 2000 Index. Currently, we have a significant
     percentage of holdings in biotech, telecommunications and technology. We
     are active investors in initial public offerings (IPOs). As of November 30,
     1999, 40.75% of the portfolio was in cash and cash equivalents. This is a
     result of steady inflows into the Fund paired with our patience for the
     right buying opportunities. I expect this to decline by the end of our
     fiscal year.

Q.   HOW HAVE YOU BEEN DOING AGAINST THE RUSSELL 2000?

A.   From October 1 through November 30, 1999, Westcore Small-Cap Growth Fund
     was up 102.9%. In comparison, the Russell 2000 Index was up 6.41%. This
     outperformance is coming in part from being invested in technology IPOs
     such as Sycamore, Interwoven and Finisar. Sycamore facilitates high-speed
     traffic over fiber-optic networks used by the major telecommunications
     companies. Interwoven is a software company that helps companies manage
     their customer data. Finisar helps companies store data more efficiently.
     These companies are selling at extremely high valuations. However, the
     market is currently driven by positive and negative information flow, not
     traditional measures such as price-earnings ratios. We think investors
     should understand that these kinds of IPO returns -- 100% gains or more in
     a matter of weeks -- are not typical.

Q.   DO YOU HAVE ACCESS TO IPO OPPORTUNITIES THAT THE AVERAGE INDIVIDUAL
     INVESTOR WOULDN'T HAVE?

A.   Yes, because we maintain a business relationship with the major investment
     banking houses on Wall Street. They provide us with research, including
     access to companies that they are taking public. In the current frothy IPO
     market, this access is critical. Rather than wait a year or two until they
     produce a track record or obtain interim financing, some companies are
     coming public today without profits -- or even revenues in some cases.

Q.   BESIDES THE IPO MARKET, WHERE ELSE HAVE YOU GENERATED GOOD RESULTS?

A.   One major beneficiary of the Internet boom is radio. Westwood One, a major
     radio network, has benefited greatly from "dot.com" advertising this year.
     It is ironic, but these "new media" Internet companies are going to
     traditional media to get their message across. Radio has advantages over
     television and print as an ad medium, because radio is less expensive and
     easier to target a particular audience.

Q.   WHERE HAVE YOU BEEN DISAPPOINTED?

A.   Our energy investments have not done as well as expected, primarily because
     of unseasonably warm fall weather throughout the U.S. Another holding has
     done poorly in part because a prominent investment

     newsletter recommended that its clients sell the stock short. But these are
     minor negatives, considering the fund's performance.

Q.   HAVE YOU MET WITH THE MANAGEMENT OF ALL THE COMPANIES IN YOUR PORTFOLIO?

A.   We speak to the management of all the companies we invest in and meet with
     most of them in person. You can learn a lot from these meetings. People can
     convey confidence, concern or hesitation that you can't get through written
     or financial reports. Recently, we met with the top executive of a company
     who was visibly nervous when we asked him about a planned diversification.
     We concluded that he was uncomfortable with his decision and did not invest
     in his company.

Q.   WHAT IS YOUR CURRENT OUTLOOK FOR THE SMALL-CAP MARKET?

A.   The current state of affairs -- in which companies with no earnings do much
     better than those with profits -- is unlikely to continue. But overall, we
     are bullish on the small-cap market. The Federal Reserve Board continues to
     manage the economy for continued growth and low inflation. But even if
     there happened to be a market correction, we would see that as a buying
     opportunity.

Average annual total returns reflect reinvestment of all dividends, capital
gains distributions, all fee waivers in effect and any expense reimbursements.
Without the fee waivers and expense reimbursements, the total return figures
would have been lower. Fund inception date is 10/1/99. Past performance is not
indicative of future results. Principal value may fluctuate and shares, when
redeemed, may be worth more or less than their original cost.

This Fund participates in the Initial Public Offering (IPO) market, and a
significant portion of the fund's returns have been attributable to its
investment in IPOs, which in turn have had a magnified impact due to the fund's
relatively small asset base. As the Fund's assets continue to grow, it will be
increasingly less likely to experience substantially similar performance by
investing in IPOs.

WESTCORE SELECT FUND

FUND OBJECTIVE: Seeks long-term growth of capital primarily through investments
in companies of any size selected for their growth potential.

Q.   SINCE THE FUND IS NEW AS OF OCTOBER 1, 1999, LET'S FIRST DISCUSS YOUR
     INVESTMENT STRATEGY.

A.   This is a concentrated portfolio of 20 to 35 stocks with an emphasis on
     emerging sectors and themes of the market that are expected to be in vogue.
     Sectors that are not currently being emphasized are those that are out of
     favor such as banks and insurance companies. Our goal is to outperform the
     Standard & Poor's 500 Index, although no attempt is made to match the index
     in terms of sectors or market capitalization.

Q.   HOW HAS THE FUND PERFORMED?

A.   From October 1 through November 30, 1999, Westcore Select Fund was up
     57.10%. In comparison, the S&P 500 Index was up 8.49% during the same time
     period. One reason for the outperformance is that we began the Fund on
     October 1 with 100% cash. The market was near a low at that point, so we
     had a lot of buying power at the right time and found some interesting
     companies. We were also helped meaningfully by investing in selected
     initial public offerings (IPOs). One example is Martha Stewart Living
     Omnimedia, the creator of "how to" content and related products for
     homemakers, which leverages the Martha Stewart brand name across a range of
     media and retail outlets. We participated when the company went public in
     October at $18 and sold it soon after that at $38, because we believed that
     the company was overvalued. The stock was at $30 on November 30.

Q.   DO YOU HAVE ACCESS TO IPO OPPORTUNITIES THAT THE AVERAGE INDIVIDUAL
     INVESTOR WOULDN'T HAVE?

A.   Yes, because we maintain a business relationship with the major investment
     banking houses on Wall Street. They provide us with research, including
     access to companies that they are taking public. In the current frothy IPO
     market, this access is critical.

Q.   DESCRIBE THE FUND'S LARGEST HOLDING AT NOVEMBER 30, 1999.

A.   In early November, we purchased shares in ProsoftTraining.com, which offers
     Internet training and certification programs to individuals and
     corporations. The company is profitable, unlike most Internet-related
     companies, but it isn't well known on Wall Street. We think that the
     company's shares have substantial upside potential based on its recent
     growth in revenues and earnings.

Q.   WHAT WAS ANOTHER BIG WINNER DURING THE PERIOD?

A.   Another successful holding was Westwood One, a leading radio network, which
     is benefiting from the surge in "dot.com" advertising. Nearly half of all
     Internet advertising is on radio, because it is inexpensive and easily
     targeted to specific demographics.

Q.   WHAT HAS BEEN A PARTICULAR CHALLENGE FOR YOU?

A.   Even though we have made substantial profits in technology stocks, and have
     sold the ones that appear overvalued, they continue to go up. This is a
     two-tier market: more than half of the stocks in the S&P 500 Index are down
     for the year. You have to be in technology to do well.

Q.   WHAT IS YOUR OUTLOOK ON THE MARKET?

A.   Overall positive, though I have a number of concerns, including rising
     interest rates and the speculative environment surrounding the IPO market.
     While I'm very gratified with our inaugural performance, it is unrealistic
     to expect it to continue at this pace. However, I'm an aggressive investor
     who has more than 30 years of experience in the investment business -- and
     this Fund will be a reflection of my strong convictions.

              SEMI-ANNUAL REPORT NOVEMBER 30, 1999 -- (CONTINUED)

WESTCORE BLUE CHIP FUND

FUND OBJECTIVE: Seeks to maximize long-term total return by investing in stocks
of large, well-established companies whose stocks appear to be undervalued.

Q.   HOW DID THE FUND PERFORM?

A.   For the six-months ended November 30, 1999, Westcore Blue Chip Fund's total
     return was -3.08%. In comparison, the Standard & Poor's Barra Large Cap
     Value Index returned -1.00% while the S&P 500 Index was up 7.36%.

Q.   WHAT FACTORS AFFECTED PERFORMANCE?

A.   Investors continued to prefer growth stocks -- particularly technology
     companies -- versus value. As an illustration, the S&P Barra Large Cap
     Growth Index was up 15.30% for the period, more than double the S&P 500
     Index.

Q.   HAVE YOU MADE ANY CHANGES TO YOUR INVESTMENT STYLE?

A.   We have remained committed to our discipline of investing in attractively
     valued, well-established companies that have low price-to-earnings, low
     price-to-book value and low price-to-cash flow ratios. In addition, we use
     a blended approach of quantitative research and qualitative
     decision-making. However, we recognize that the marketplace has
     increasingly rewarded growth, and it raises the bar for all companies in
     terms of business and investment performance. We have made adjustments to
     our quantitative process that allows us to identify -- and perhaps
     favor -- stocks that have higher growth rates. At the same time, we have
     added to our quantitative research staff, deepening our expertise in
     monitoring the stocks that we own and identifying new candidates.

Q.   WHAT STOCKS HAVE PERFORMED PARTICULARLY WELL?

A.   We bought two technology companies -- Adobe Systems, a leader in the
     electronic document marketplace, and Apple Computer -- when they were in
     the process of retooling their businesses. They weren't at risk of going
     out of business, but they were not on the radar screen for investors
     looking for high-growth technology stocks. As a result, their share prices
     were very reasonable and we were able to benefit greatly when the
     companies' performance improved. In the telecommunications field, we
     benefited from ALLTEL's diversification from a telephone utility into the
     cellular telephone market as well as Motorola's reemergence as a leader in
     wireless telecommunications.

     Although technology was dominant, it wasn't the area of strong performance
     for the portfolio. Our purchase of Lehman Brothers at the height of the
     Asian economic crisis was rewarded when the global economy improved and
     the investment business looked attractive again. Morgan Stanley Dean
     Witter was another strong stock as the firm emerged as an even stronger
     player in a consolidating global financial services industry. In media,
     Viacom was an excellent performer as it benefited from strong advertising
     revenue resulting from a booming U.S. economy. In addition, Viacom is
     diversifying internationally, including a foray into China.

Q.   WHAT AREAS WERE DIFFICULT?

A.   Consumer staples such as food and drug stores had a tough six-months as
     investors shifted funds from these defensive areas into technology. Many of
     these companies are experiencing double-digit growth, but it's an
     overlooked sector which bodes well for future opportunity. To be sure, the
     price of large-cap technology stocks has made almost everything else look
     very reasonable.

Q.   WHAT IS YOUR OUTLOOK?

A.   We believe that technology will still be in favor in the near future, and
     it's not possible to predict when investor sentiment will shift. But we
     think that it is prudent from a risk standpoint to take some profits from
     technology and expand into some of these overlooked areas.

WESTCORE MID-CAP OPPORTUNITY FUND

FUND OBJECTIVE: Seeks to maximize long-term capital appreciation by investing
primarily in medium-sized companies whose stocks appear to be undervalued.

Q.   HOW DID THE FUND PERFORM?

A.   For the six months ended November 30, 1999, the Fund returned 15.20%. In
     comparison, the Fund's benchmark, the Russell Midcap Index, rose 1.96%.

Q.   WHAT FACTORS AFFECTED YOUR PERFORMANCE?

A.   We look at today's market as being divided into "new economy" companies,
     such as technology and telecommunications that are soaring, and "old
     economy" companies, such as the autos, aerospace and housing. Rather than
     dismissing the new economy stocks because their valuations are in the
     stratosphere, our strategy has been to invest in the best values within
     those hot sectors. We decided that it was better to own the value play in
     the new economy than to sit on the sidelines and dismiss it entirely
     because valuations are high. It turns out there are technology and
     telecommunications companies with earnings that we can justify owning, even
     in this value fund.

Q.   WHAT ARE SOME EXAMPLES?

A.   We bought Apple Computer when it was out of favor but still profitable, and
     the stock has been one of the portfolio's best performers. The company,
     which focuses on the education and the graphic artist markets, has a new
     product lineup that is selling so well the company is having trouble
     keeping up with demand. Companies that deliver Internet connections to the
     consumer are selling at astronomical price-earnings ratios, so we bought
     Cincinnati Bell, a telephone utility that is turning into a "bandwidth"
     company, because at the time it was valued like a telephone utility. In the
     cellular telephone industry, we purchased shares in U.S. Cellular, which
     offers wireless services in rural markets where there is less competition.

     In financial services, Lehman Brothers has been a major beneficiary of the
     improvement in global economies and the surge in initial public offerings
     as well as merger and acquisition activity. In banking, UnionBanCal has had
     very good loan growth in a booming California economy -- and they're
     repurchasing shares, which has bolstered the stock price.

Q.   WHAT HAS BEEN DISAPPOINTING?

A.   It has been disappointing that the stock prices of excellent industrial
     companies such as Dana and Johnson Controls have performed poorly. One
     reason is the general flow of money into new economy stocks where growth is
     accelerating, not decelerating. Another reason is that we are very late
     into an extended economic cycle, and there's a belief that the Federal
     Reserve Board will have to raise interest rates to slow down the economy.
     As a result, these industrial companies have probably seen the best growth
     they're going to see for a while.

Q.   HAVE YOU MADE ANY CHANGES TO YOUR INVESTMENT PROCESS?

A.   An adjustment that we've made to our process is to be less tolerant of
     stocks that aren't working. For example, we sold Kmart even though the
     company was fundamentally healthy and the stock was selling at just 7 times
     earnings. The stock was not performing, and there was little demand for its
     shares. We want to own stocks that other people want to own, too. Sometimes
     economic sectors define returns more than stock selection. In the current
     environment, you can own the worst company in a hot industry and you'll
     make more money than owning the best company in a declining one.

Q.   WHAT IS YOUR OUTLOOK?

A.   My outlook is very favorable. This is the first time in five years that
     mid-cap companies have actually outperformed large-cap stocks. As value
     investors, we think that we have a lower-risk way to capture these returns.
     I'm very excited about the fact that the U.S. economy has spawned these
     emerging industries in technology and telecommunications. It's a real
     testament to American ingenuity and entrepreneurialism.

This Fund participates in the Initial Public Offering (IPO) market, and a
significant portion of the fund's returns have been attributable to its
investment in IPOs, which in turn have had a magnified impact due to the fund's
relatively small asset base. As the Fund's assets continue to grow, it will be
increasingly less likely to experience substantially similar performance by
investing in IPOs.

WESTCORE SMALL-CAP OPPORTUNITY FUND

FUND OBJECTIVE: Seeks to maximize long-term capital appreciation primarily
through investments in companies with small capitalizations whose stocks appear
to be undervalued.

Q.   HOW DID THE FUND PERFORM?

A.   For the six-months ended November 30, 1999, Westcore Small-Cap Opportunity
     Fund's total return was -5.79%. In comparison, the Russell 2000 Index
     returned 4.19%.

Q.   WHAT FACTORS AFFECTED PERFORMANCE?

A.   Investors continued to prefer growth stocks -- particularly technology
     companies -- over value. As an illustration, the Russell 2000 Growth Index,
     a measure of small-cap growth, was up 13.51% for the period. Contrary to
     long-term investment research, stocks with the highest price-to-book value
     ratios have performed the best, while stocks with the lowest price-to-book
     value ratios performed poorly.

Q.   HOW WOULD YOU DESCRIBE YOUR INVESTMENT STYLE?

A.   We remained committed to our philosophy of investing in attractively valued
     companies that have low price-to-earnings, low price-to-book value and low
     price-to-cash flow ratios. These measures have proven to work over time.
     However, we recognize that the marketplace has increasingly rewarded
     growth, and it raises the bar for all companies in terms of business and
     investment performance. We have made adjustments to our quantitative
     process that allows us to identify -- and perhaps favor -- stocks that have
     higher growth rates. We find that small-cap growth stocks outside of
     technology are very inexpensively valued today.

Q.   WHAT STOCKS HAVE PERFORMED PARTICULARLY WELL?

A.   As you might expect, technology was very strong. For instance, In Focus
     Systems' stock was languishing just prior to the introduction of a new
     micro digital projector that created triple-digit earnings growth for the
     company. We bought this stock just prior to this product introduction, and
     the stock has since more than doubled. Another technology company, Best
     Software, was performing poorly due to concerns about Y2K. The company's
     human resources software is marketed to customers that were thought to be
     freezing software purchases until after 1999. We purchased the stock during
     this so-called lockdown period, and the result has been a strong gain. In
     electronics retailing, Rex Stores, which focuses on rural communities, is
     benefiting from the transition towards digital video technology, and its
     stock performed very well. Finally, more than a dozen companies in the
     portfolio were bought out during the six-month period, which is encouraging
     because it is an external vote of confidence that we are identifying cheap
     stocks with good businesses.

Q.   WHAT AREA HAS BEEN PARTICULARLY DIFFICULT?

A.   Small-cap financial stocks have had a difficult time. Unlike the large-cap
     world where financials are attractive as a result of globalization,
     small-cap financials have been battered by rising interest rates.

Q.   WHAT IS YOUR OUTLOOK?

A.   Even though it has been a tough year for value investors, we are
     optimistic. Although we don't know how long the current preoccupation with
     technology will continue, we believe that it is risky to go against
     long-term research that indicates that buying stocks at low
     price-to-earnings and price-to-book-value ratios is a profitable strategy.
     We will continue to hone our long-term strategy as a small-cap value
     investor. Recently, we have added to our quantitative research staff,
     deepening our expertise in monitoring the stocks that we own and our
     ability to identify new candidates. We agree that technology has further to
     run and it's not possible to predict when investor sentiment will shift.
     But we think that it

              SEMI-ANNUAL REPORT NOVEMBER 30, 1999 -- (CONTINUED)

WESTCORE LONG-TERM BOND FUND

FUND OBJECTIVE: Seeks to maximize long-term total rate of return by investing
primarily in investment-grade bonds.

Q.   HOW DID THE FUND PERFORM?

A.   For the six-month period ended November 30, 1999, the Westcore Long-Term
     Bond Fund's total return was -1.95%. In comparison, the unmanaged Lehman
     Brothers Long-Term Government/Corporate Index returned -1.70%. A bond
     portfolio's total return equals its coupon income plus or minus changes in
     bond prices. In a period of rising interest rates, bond prices typically
     fall. However, the income that a bond portfolio produces tends to rise. As
     of November 30, 1999, the Westcore Long-Term Bond Fund's 30-day SEC yield
     was 6.61%(1).

Q.   WHAT ECONOMIC FACTORS AFFECTED THE BOND MARKET?

A.   The U.S. economy continued to grow at a very strong clip, prompting the
     Federal Reserve Board to raise short-term interest rates three times to
     5.50%. This reverses the action the Fed took in late 1998 to ignite the
     U.S. economy in the face of a global economic crisis and deflation fears.
     One year later, the global economy has improved, oil prices have more than
     doubled and investors are now concerned about inflation. That's why
     long-term bond yields have moved up.

Q.   HOW DID Y2K AFFECT THE CORPORATE BOND MARKET?

A.   The Y2K concern prompted corporations to issue more bonds earlier in the
     year and avoid trying to raise money at the end of 1999. As a result of
     this additional supply, the spread between corporate bond yields and U.S.
     Treasury bonds of similar maturity was unusually wide for several months.
     Since bond prices typically move inversely to yields, the result was lower
     corporate bond prices. Also, due to the federal budget surplus that created
     a diminished need for federal government borrowing, the supply of U.S.
     Treasury securities has been reduced. However, by the end of the fiscal
     year, most of the underperformance from corporate bonds had disappeared,
     and the Y2K impact turned out to be modest.

Q.   WHAT FACTORS AFFECTED THE FUND'S PERFORMANCE?

A.   We added value by owning bonds that provided more income than U.S. Treasury
     bonds, such as investment-grade corporate bonds. The portfolio holds
     approximately 49% in corporates, which is higher than the 35% allocated in
     the Index. In addition, we chose to maintain a slightly shorter "duration"
     than the benchmark for most of the time period, based on our view that the
     Fed would have to tighten the money supply. The duration of a portfolio
     refers to its sensitivity to changes in interest rates. By keeping duration
     slightly shorter than average, the portfolio was insulated somewhat from
     the impact of rising interest rates.

Q.   DESCRIBE A RECENT ACQUISITION THAT ILLUSTRATES YOUR STRATEGY.

A.   We added an enhanced equipment trust certificate that's backed by US
     Airways aircraft. We're buying the senior debt, so we've got the airline
     and the airplanes backing the bonds -- and the company's other debt are
     subordinated to us. It's a high-quality asset, and the bonds yielded 8.36%
     at the time of purchase, more than 2 full percentage points over U.S.
     Treasury bonds.

Q.   WHAT IS YOUR OUTLOOK?

A.   In the past 15 years, there have only been two years in which bonds
     produced negative returns, and that's 1994 and 1999, when interest rates
     rose sharply. If interest rates level off or decline in 2000, total

     returns on bonds will improve. In the meantime, long-term investors will
     continue to enjoy income from bonds well in excess of current inflation
     rates.

WESTCORE INTERMEDIATE-TERM BOND FUND

FUND OBJECTIVE: Seeks current income with less volatility of principal than
funds with longer maturities by investing primarily in investment-grade bonds.

Q.   HOW DID THE FUND PERFORM?

A.   For the six-month period ended November 30, 1999, the Westcore
     Intermediate-Term Bond Fund's total return was 0.93%. In comparison, the
     unmanaged Lehman Brothers Intermediate Government/ Corporate Index returned
     1.37%. A bond portfolio's total return equals its coupon income plus or
     minus changes in bond prices. In a period of rising interest rates, bond
     prices typically fall. However, the income that a bond portfolio produces
     tends to rise. As of November 30, 1999, the Westcore Intermediate-Term Bond
     Fund's 30-day SEC yield was 6.46%(1).

Q.   WHAT FACTORS AFFECTED THE BOND MARKET?

A.   Despite efforts by the Federal Reserve Board to slow down the U.S. economy,
     it continued to grow at a much faster rate than projected just a year
     earlier. In late 1998, a global economic crisis was threatening to throw
     the U.S. economy into its first recession since 1990-1991. By early 1999,
     those fears evaporated. The U.S. economy continued to grow at a good clip,
     prompting the Federal Reserve Board to raise short-term interest rates
     three times to 5.50%. Long-term interest rates followed suit, as bond
     investors demanded extra yield to compensate them for the uptick in
     inflation in 1999.

Q.   WHAT FACTORS AFFECTED THE FUND'S PERFORMANCE?

A.   We added value by owning bonds that provided more income than U.S. Treasury
     bonds, such as asset-backed securities and real estate investment trusts
     (REITs). Asset-backed securities are typically rated AAA and, as the name
     implies, are backed by assets such as accounts receivable or credit card
     debt. Our REIT investments tend to be lower-risk real estate such as
     industrial property with very high occupancy rates. Our investments in
     corporate bonds include such household names as Ford Motor Credit, Time
     Warner and Wells Fargo Bank.

Q.   DESCRIBE A RECENT ACQUISITION THAT ILLUSTRATES YOUR STRATEGY.

A.   We added an enhanced equipment trust certificate that is backed by
     Continental Airlines aircraft. We're buying the senior debt, so we've got
     the airline and the airplanes backing the bonds -- and the company's other
     debt are subordinated to us. It's a high-quality asset, and the bonds
     yielded 7.57% at the time of purchase, significantly more than U.S.
     Treasury bonds.

Q.   WHAT IS YOUR OUTLOOK?

A.   We believe that the Federal Reserve Board will continue to do a good job of
     containing inflation. Meanwhile, the federal budget surplus will reduce the
     supply of U.S. Treasury bonds, exerting upward pressure on bond prices. The
     last year of negative bond returns -- 1994, was followed by four years of
     double-digit gains. If interest rates level off or decline in 2000, total
     returns on bonds will improve. In the meantime, patient investors will
     continue to enjoy income from bonds well in excess of current inflation
     rates.

WESTCORE COLORADO TAX-EXEMPT FUND

FUND OBJECTIVE: Seeks to provide income exempt from both federal and Colorado
state personal income taxes by emphasizing Colorado municipal bonds with
intermediate maturities.

Q.   HOW DID THE FUND PERFORM OVER THE PAST SIX MONTHS?

A.   For the six-month period ended November 30, 1999, Westcore Colorado
     Tax-Exempt Fund's total return was -1.57%. In comparison, the unmanaged
     Lehman Brothers 10-Year Municipal Bond Index returned -1.87%. Total returns
     reflect the generally rising interest rate environment, since bond prices
     move inversely to changes in interest rates. However, bond yields rose,
     thus offering investors income that was substantially in excess of the
     inflation rate, generally believed to be 2% to 2.5%. As of November 30,
     1999, the Fund's 30-day SEC yield was 4.41%. For taxpayers in a combined
     Federal and Colorado income tax bracket of 34.28%, that equates to a
     tax-equivalent yield of 6.71%(1).

Q.   HOW WOULD YOU DESCRIBE THE MUNICIPAL BOND ENVIRONMENT OVER THE PERIOD?

A.   Because interest rates rose during the six months ending November 30, 1999,
     the environment was difficult for bonds in general. More specifically, the
     municipal bond market, which is heavily influenced by supply and demand,
     was relatively inactive during the period. Supply was scarce, as
     municipalities preferred not to pay higher interest rates on their debt. In
     addition, the strong economy has generated surging tax revenues for
     municipalities, reducing the need to borrow. Meanwhile, the demand for
     municipal bonds has been constrained by unusually attractive U.S. Treasury
     bond yields. As a result, institutional buyers such as insurance companies
     have not been actively buying municipal bonds.

Q.   WHAT FACTORS AFFECTED YOUR PERFORMANCE?

A.   Because of rising interest rates, a number of bonds in the portfolio were
     trading at discounts to par. The bonds were further discounted in value,
     because they became subject to the federal market discount tax rules. The
     market discount tax rules require investors who purchase bonds at
     significant discounts to report ordinary income, taxed as high as 39.6% at
     the federal level, rather than capital gains, taxed at 20%, when they later
     sell the bonds at a profit. Such bonds trade at a lower price because
     investors demand an after-tax yield to offset the higher taxes they must
     pay.

     On the plus side, the fund was positively impacted by our decision to stick
     to high-quality bonds, which outperformed lower-quality securities. In
     addition to our rigorous examination of the creditworthiness of a bond,
     about 75% of the portfolio was insured as of November 30, 1999.

Q.   WHAT OTHER STRATEGIES DID YOU EMPLOY DURING THE PERIOD?

A.   We have tended to purchase premium bonds with higher coupons in the 5.5% to
     6.5% range. These bonds hold up better in a rising interest rate
     environment, and they are unlikely to be subject to the market discount tax
     rule. For example, we purchased AAA-rated Douglas County school district
     bonds offering a 6.5% coupon due in 2016. Because the bonds will be
     pre-refunded with U.S. government securities as collateral in 2004, the
     bonds are less volatile, because they trade as if they have a five-year
     maturity. Another way we enhanced yield was to purchase certificate of
     participation (COP) bonds. They offer extra yield, because they're
     considered less liquid than other municipal bonds. For instance, we
     purchased some El Paso County COPs due in 2002, which yielded 0.15
     percentage points more than a standard AAA-rated general obligation bond of
     similar short maturity. Bonds in the portfolio with lower coupons in the
     4.25% to 4.75% range tended to be sold first when we had cash requirements.

              SEMI-ANNUAL REPORT NOVEMBER 30, 1999 -- (CONTINUED)

Q.   WHAT IS YOUR OUTLOOK FOR THE FUND?

A.   The Colorado economy continues to be very strong, with unemployment at
     historically low levels, a booming housing market and rising personal
     disposable incomes. As a result of the past election in which voters
     approved new highway construction and improvements, the supply of bonds
     should increase sharply in 2000. We expect to see $5 billion in general
     obligation bonds to fund these programs, the first of their kind for the
     state of Colorado. In addition, we should see a significant amount of
     school and convention center bond issues coming to market. In short, supply
     should increase while we see rising demand from investors looking for high
     tax-free income on high-quality securities.

(1) A portfolio turnover rate is, in general, the percentage computed by taking
    the lesser of purchases or sales of portfolio securities (excluding
    securities with a maturity date of one year or less at the time of
    acquisition) for a period and dividing it by the monthly average of the
    market value of such securities during the period. Purchases and sales of
    investment securities (excluding short-term securities) for the period ended
    November 30, 1999 were $124,044,583 and $163,069,951, respectively.

(2) Annualized.

                         NOTES TO FINANCIAL STATEMENTS
                         NOVEMBER 30, 1999 (UNAUDITED)

1. SIGNIFICANT ACCOUNTING POLICIES

     Westcore Trust (the "Trust") is registered under the Investment Company Act
of 1940, as amended, as an open-ended management investment company. Interests
in the Westcore MIDCO Growth, Westcore Growth and Income, Westcore Small-Cap
Growth, Westcore Select, Westcore Blue Chip, Westcore Mid-Cap Opportunity,
Westcore Small-Cap Opportunity, Westcore Long-Term Bond, Westcore Intermediate-
Term Bond and Westcore Colorado Tax-Exempt Funds ("the Funds") are represented
by separate classes of beneficial interest of the Trust, which is organized as a
Massachusetts business trust. The Funds, for book and tax purposes, have a
fiscal year of May 31. From October 11, 1993 to September 30, 1995, Westcore
MIDCO Growth, Westcore Growth and Income, Westcore Small-Cap Opportunity and
Westcore Intermediate-Term Bond Funds offered Institutional and Retail classes
of shares with a front-end load and their own distribution/administrative
service plan. On October 1, 1995 the Retail class was merged into the
Institutional class at the respective net asset value per share. The
distribution/administrative service plan on the Retail class was discontinued.
The front-end sales load on all the Funds was also discontinued.

     The following is a summary of significant accounting policies consistently
followed by each Fund in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles for
investment companies.

     USE OF ESTIMATES -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures in
the financial statements. The actual results could differ from those estimates.

     INVESTMENT VALUATION -- Securities of the Funds are valued as of the close
of regular trading on the New York Stock Exchange (the "NYSE"), currently 4:00
p.m. (Eastern time), on each day that the NYSE is open. Listed and unlisted
securities for which such information is regularly reported are valued at the
last sales price of the day or, in the absence of sales, at values based on the
average closing bid and asked price. Securities for which market quotations are
not readily available are valued under procedures established by the Board of
Trustees to determine fair value in good faith. Short-term securities having a
remaining maturity of 60 days or less are valued at amortized cost which
approximates market value.

     FEDERAL INCOME TAXES -- It is the Funds' policy to continue to comply with
the provisions of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of their taxable income to shareholders.
Therefore, no federal income tax provision is required. At May 28, 1999 the
Westcore Mid-Cap Opportunity, Westcore Small-Cap Opportunity, Westcore
Intermediate-Term Bond and Westcore Colorado Tax-Exempt Funds had available for
federal income tax purposes unused capital loss carryovers of $53,504,
$2,328,989, $1,115,999 and $35,421, respectively, which will expire through
2007.

     The Westcore Mid-Cap Opportunity and Westcore Small-Cap Opportunity Funds
intend to elect to defer to their fiscal year ending May 31, 2000, $150,778 and
$7,427,671 of losses, respectively, recognized during the period November 1,
1998 to May 28, 1999.

     During the year ended May 28, 1999, the Westcore MIDCO Growth Fund had
redemption-in-kind transactions in the amounts of $163,612,554, based on the
fair market value of the individual securities within the portfolio. These
transactions resulted in short-term and long-term gains of $15,506,744 and
$28,537,817, respectively, which will be recognized as permanent differences for
tax purposes.

     CLASSIFICATION OF DISTRIBUTIONS TO SHAREHOLDERS -- Net investment income
(loss) and net realized gain (loss) may differ for financial statement and tax
purposes. The character of distributions made during the year from net
investment income or net realized gains may differ from its ultimate
characterization for federal income tax purposes. Also, due to the timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the fiscal year in which the income or realized gain was recorded by
the Funds.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                         NOVEMBER 30, 1999 (UNAUDITED)

     DISTRIBUTIONS -- Distributions of net investment income, if any, are
distributed annually for the Westcore MIDCO Growth, Westcore Small-Cap Growth
and Westcore Select Funds, quarterly for the Westcore Growth and Income,
Westcore Blue Chip, Westcore Mid-Cap Opportunity and Westcore Small-Cap
Opportunity Funds and monthly for the Westcore Long-Term Bond, Westcore
Intermediate-Term Bond, and Westcore Colorado Tax-Exempt Funds. Distributions of
net realized gains, if any, are declared at least once each year for each of the
Funds. Distributions to shareholders are recorded on the ex-dividend date.

     ORGANIZATION COSTS -- Costs incurred in connection with the organization,
initial registration and public offering of shares have been paid by the Funds.
These costs are expensed as incurred.

     SECURITIES LENDING -- The Westcore Funds may loan securities to certain
brokers who pay the Funds negotiated lenders' fees. These fees, net of
associated costs, are included in other income. The Funds receive U.S. Treasury
obligations and/or cash as collateral against the loaned securities, in an
amount at least equal to 102% of the market value of the loaned securities at
the inception of each loan. This collateral must be maintained at not less than
100% of the market value of the loaned securities during the period of the loan.
The risks to the Funds of securities lending are that the borrower may not
provide additional collateral when required or return the securities when due.
As of November 30, 1999, the value of securities loaned of the Westcore MIDCO
Growth, Westcore Blue Chip, Westcore Small-Cap Opportunity and Westcore Long-
Term Bond Funds amount to $59,972,880, $2,727,094, $703,113 and $525,320,
respectively. The value of collateral of the Westcore MIDCO Growth, Westcore
Blue Chip, Westcore Small-Cap Opportunity and Westcore Long-Term Bond Funds
amounts to $62,040,962, $2,875,001, $747,485 and $540,000, respectively.

     ALLOCATION OF INCOME, EXPENSES AND GAINS AND LOSSES -- Trust expenses,
which are not series specific, are allocated to each series based upon its
relative proportion of net assets and/or open accounts to the Trust's totals.
From October 11, 1993 to September 30, 1995 the Westcore MIDCO Growth, Westcore
Growth and Income, Westcore Small-Cap Opportunity, and Westcore
Intermediate-Term Bond Funds allocated income, expenses (other than the class
specific expenses) and gains and losses daily to each class of shares based upon
their relative proportion of net assets represented by each class. Operating
expenses directly attributable to a specific class were charged against the
operations of that class.

     WHEN-ISSUED SECURITIES -- Each Fund may purchase or sell securities on a
"when issued" or "forward commitment" basis which involves a commitment by the
Fund to purchase or sell particular securities with payment and delivery taking
place at a future date. During this period, such securities do not earn
interest, are subject to market fluctuation and may increase or decrease in
value prior to their delivery. Each Fund maintains, in a segregated account with
its custodian, assets with a market value at least equal to the amount of its
purchase commitments. The purchase of securities on a when-issued or forward
commitment basis may increase the volatility of the Fund's net asset value to
the extent each Fund makes such purchases while remaining substantially fully
invested.

     OTHER -- Investment transactions are accounted for on the date the
investments are purchased or sold (trade date). Dividend income is recorded on
the ex-dividend date. Interest income, which includes amortization of premiums,
accretion of discounts and income earned on money market funds, is accrued and
recorded daily. Realized gains and losses from investment transactions and
unrealized appreciation and depreciation of investments are reported on an
identified cost basis.

4. INVESTMENT ADVISORY FEES, ADMINISTRATIVE FEES AND OTHER RELATED PARTY
   TRANSACTIONS

     The Trust has entered into an advisory agreement with Denver Investment
Advisors LLC ("DIA"), for all Funds. DIA succeeded First Interstate Capital
Management, Inc. ("FICM") as investment adviser to the Westcore Long-Term Bond
and the Westcore Colorado Tax-Exempt Funds on October 1, 1995. The advisory
agreement has been approved by the Trust's Board of Trustees and shareholders
and contains terms and conditions similar to those which were in these Funds'
former advisory agreement.

     Pursuant to its advisory agreement with the Trust, DIA is entitled to an
investment advisory fee, computed daily and payable monthly of 0.65%, 0.65%,
1.00%, 0.65%, 0.65%, 0.75%, 1.00%, 0.45%, 0.45% and 0.50% of the average net
assets for Westcore MIDCO Growth, Westcore Growth and Income, Westcore Small-Cap
Growth, Westcore Select, Westcore Blue Chip, Westcore Mid-Cap Opportunity,
Westcore Small-Cap Opportunity, Westcore Long-Term Bond, Westcore
Intermediate-Term Bond and Westcore Colorado Tax-Exempt Funds, respectively.

     Effective October 1, 1995, ALPS Mutual Fund Services, Inc. ("ALPS") and DIA
entered into an administrative agreement to serve as the Funds
co-administrators. ALPS and DIA are entitled to receive a fee from each Fund for
its administrative services computed daily and paid monthly, at the annual rate
of 0.30% of the Fund's average net assets.

     The Co-Administrators and the Investment Adviser have advised the Trust
that they currently intend to waive fees or reimburse expenses with respect to
each of the Funds so that the Total Operating Expenses of the Westcore MIDCO
Growth, Westcore Growth and Income, Westcore Small-Cap Growth, Westcore Select,
Westcore Blue Chip, Westcore Mid-Cap Opportunity, Westcore Small-Cap
Opportunity, Westcore Long-Term Bond, Westcore Intermediate-Term Bond and
Westcore Colorado Tax-Exempt Funds will not exceed 1.15%, 1.15%, 1.30%, 1.15%,
1.15%, 1.25%, 1.30%, 0.95%, 0.85%, and 0.65%, respectively. Without such fee
waivers, for the period ended November 30, 1999, the Total Operating Expenses of
the Westcore MIDCO Growth, Westcore Growth and Income, Westcore Small-Cap
Growth, Westcore Select, Westcore Blue Chip, Westcore Mid-Cap Opportunity,
Westcore Small-Cap Opportunity, Westcore Long-Term Bond, Westcore
Intermediate-Term Bond, and Westcore Colorado Tax-Exempt Funds would be 1.31%,
1.85%, 2.58%, 2.00%, 1.27%, 3.47%, 1.64%, 1.24%, 1.08%, and 1.09%, respectively.

     Certain officers of the Funds are also officers of DIA. All affiliated and
access persons, as defined in the 1940 Act, follow strict guidelines and
policies on personal trading as outlined in the Trust's Code of Ethics.

     Expenses for the Funds include legal fees paid to Drinker Biddle & Reath
LLP. A partner of that firm is secretary of the Trust.

     The Trust has a Trustee Deferred Compensation Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of Trustees
Fees. The deferred fees are invested in certain Westcore Funds until
distribution in accordance with the Deferral Plan.

     Shareholders holding more than 5% of the Funds' outstanding shares as of
November 30, 1999, constituted 22.05% of Westcore MIDCO Growth Fund, 35.33% of
Westcore Growth and Income Fund, 35.41% of Westcore Small-Cap Growth Fund,
43.65% of Westcore Select Fund, 47.43% of Westcore Blue Chip Fund, 63.52% of
Westcore Mid-Cap Opportunity Fund, 27.66% of Westcore Small-Cap Opportunity
Fund, 61.92% of Westcore Long-Term Bond Fund, 59.45% of Westcore
Intermediate-Term Bond Fund and 10.94% of Westcore Colorado Tax-Exempt Fund.

DIA representing 7.66% of Westcore Select Fund, 63.52% of Westcore Mid-Cap
Opportunity Fund and 5.66% of Westcore Colorado Tax-Exempt Fund.
