MANAGEMENT'S DISCUSSION OF THE FUND PERFORMANCE

QUALITY BOND FUND


Interest rates continued to push higher in the fourth quarter spurred by
stronger than expected economic growth and a gnawing perception that the Federal
Reserve was taking a too gradualistic approach to monetary tightening and
allowing inflationary pressures to build. The rapid strength in the stock market
in the quarter also led bond market participants to assume that the growing
"wealth" effect would enhance future spending as well.

The rise in yields in the fourth quarter was significant, with the 2-year
treasury rising 61 basis points and the 30-year rising 43 basis points. The
quarter capped one of the worst years in overall fixed income market
performance. In fact for the year, the 30-year treasury yields rose 150 basis
points and posted its worst total return year ever.

The meteoric rise in yields over the past 15 months has taken the bond market to
historically cheap levels. In comparison to inflation, real yields now approach
5%, an area, which historically has produced very attractive returns in
subsequent months. Comparison on an asset allocation basis to the stock market
is stunning. The bond yield/stock yield ratio (using AAA bonds Vs the S&P
Industrials) has reached a ratio of 8 times, a level unheard of in this century.
The prior high reached was in October of 1987 when the ratio reached 4.5 times
prior to the stock market collapse.

While pressure is likely to continue in the interim as the Federal Reserve
tightens monetary policy incrementally; the bond market has to be recognized as
having discounted a significant amount of bearish news. Indeed, 75 basis points
of tightening by the summer is priced into the forward yield curve. Clearly
however, a catalyst or shift in the current paradigm is needed to sustain a
change of fortune in the bond market.

Unless or more likely until the Federal Reserve gets serious about slowing the
economy down, the obvious candidate for a catalyst is the stock market, a market
which at the moment shows no inclination toward weakness. Our guess is that when
the Federal Reserve decides to move more aggressively the stock market will feel
the greater brunt of its actions and the oversold bond market may stabilize
and/or get a bid contributing to a flatter yield curve. Our concern over the
reliance on the "wealth" effect generating outsized consumer spending and now
generating an increasing portion of corporate earnings implies that weakness in
the stock market should beget weakness in the economy and the virtuous cycle of
the past several years could reverse.

Relative performance in the fund continues to be strong. Although we ended the
year at merely 0.00% total return, that total beat most of our competitors in
the Lipper universe. Our active management style has allowed us to generate top
decile returns for the one, three, five and seven year history of our running
the fund.

PENN SERIES FUNDS, INC.
MANAGEMENT'S DISCUSSION OF THE FUND PERFORMANCE

HIGH YIELD BOND FUND


The economy's remarkable resilience was good news for many stock investors but
generally bad news for bond investors in 1999. In an attempt to forestall higher
inflation, the Federal Reserve raised interest rates three times from May to
November. These actions plus bouts of inflation jitters sent interest rates up
and bond prices down, especially for Treasuries and other high-quality bonds.

Although the year ended with a moderate show of strength, the high-yield market
had a second disappointing year. High-yield bond returns were positive but
modest, with income more than offsetting principal declines. Typically, the kind
of robust economic growth that has been benefiting consumers and job seekers
would also be a boon to high-yield bonds and, indeed, these bonds performed
better than high-quality issues, especially Treasuries.

But other developments undercut the positive influence of a healthy economy.
Rising interest rates were a negative, although their direct impact was greater
on the upper-quality tier of high-yield bonds (B rated) than on lower-quality
issues. Higher rates can also pressure highly leveraged companies, which
includes most in the noninvestment-grade universe.

Another negative was a supply and demand imbalance. New issues cascaded into the
market for the third consecutive year, and demand, particularly from mutual
funds, cooled markedly in the second and third quarters of this year. While the
1999 new issue total did not top 1997 or 1998, it was substantially higher than
any other year in the last 20. The combination of a significant demand/supply
imbalance and Y2K considerations contributed to declining liquidity in the
marketplace, which further depressed prices, especially of smaller issues.

Lastly, after a long period of relative stability the bond default rate spiked
in recent months, rising to about 4% of the U.S. market's outstanding principal
amount from approximately 1.5% at the beginning of 1999. Many of the defaulting
issues were among those brought to market in recent years, when more favorable
conditions enabled companies with less-than-robust balance sheets to sell bonds.

Not all was gloom, however. Some sectors of the high-yield market bucked the
trend, particularly the dynamic telecommunications area, which now accounts for
a quarter of the high-yield bond universe. Wireless companies were especially
strong, reflecting solid fundamentals, improving cash flow, and a consolidation
trend in their industry. In addition, the market strengthened at year-end as the
new issue volume moderated and buyers reappeared, attracted by the unusually
wide yield advantage offered by lower-quality bonds and the many securities
trading at discounts.

The difficult environment left its mark on your fund, which provided a moderate
return generated solely by income. Thanks to our risk-conscious strategy,
however, the fund held up better than the average high-yield fund and the
overall market. For the 12-month period, the fund's modest gain exceeded the
market index and the average competitor fund. These comparative results
reflected the strong performance in late 1998 and early 1999 of low-quality
bonds (rated below B) that our competitors tend to favor more than we do. The
fund's dividend yield rose during the year and is now well over 6% in real
(inflation-adjusted) terms.

Throughout the year, we continued the strategy that has proved beneficial to the
fund during the past two-year bear market in high-yield bonds. The foundations
of this strategy are intensive credit research, wide diversification, and
balanced sector allocation. In managing the portfolio's credit quality, we use a
middle-of-the-road approach in which we focus on B-rated issues while making
marginal adjustments to higher- and lower-quality bonds in line with our current
market and economic outlook. For instance, as interest rates climbed in recent
months, we trimmed our bond holdings rated BB or higher, since the higher the
quality of a bond, the more its price falls as rates rise (and vice versa). At
the same time, we also trimmed holdings rated below B as market liquidity
decreased particularly for lower-quality issues. As a result, the fund's average
credit quality remained unchanged at B+.

This credit positioning means that the fund may give up some upside potential if
the high-yield market recovers sharply, because lower-quality bonds rise the
most in a rally. Conversely, this strategy helps us reduce exposure to credit
problems, and we are comfortable with the trade-off. On the whole, your fund has
fared well during the recent rising tide of defaults. The two holdings that hit
potholes together composed less than 1% of net assets, based on their original
cost to the fund. Thus, our default experience was far better than that of the
market as a whole. Overall, the fund holds approximately 250 issues representing
about 200 different companies in 33 industries.

We continued to overweight the telecommunications area in our holdings because
of its favorable prospects. Including wireless communications, satellites,
wireline communications, long distance, and Internet service providers, the
telecom area was approximately one-quarter of fund net assets at year-end.
Wireless, which, as mentioned, performed very well, was the fund's largest
industry sector, and Nextel Communications,



<PAGE>

a wireless provider, was among the largest positions. During the fourth quarter,
we increased holdings in this sector with the addition of Voicestream Wireless.

With the revival of some commodity prices - especially oil -- from 1998's
deflationary cycle, we became a little more comfortable with bonds of "deep
cyclical" companies. Our major change in this area was to increase exposure to
energy from about 5% to 9% of net assets. We also nudged holdings higher in the
paper and paper products, but they remain modest.

While high-yield bond returns were below their long-term average in the past
couple of years, their high income and shorter durations enabled them to deliver
better performance than high-quality bonds - as you would expect in a rising
rate environment. Several factors support a more optimistic outlook for 2000,
including continued strength in the economy, the end of Y2K anxiety, and lighter
supply. However, the recent precipitous rise in Treasury bond yields and some
increased demand for high-yield bonds has narrowed the previously attractive
difference (spread) between investment-grade and noninvestment-grade bonds.
Therefore, high-yield bond valuations are not as compelling as even a few weeks
ago, so our near-term outlook is tempered.

We will continue our commitment to research and diversification, which we
believe is prudent for a fund that operates in the riskier area of the overall
bond market. Our aim is to deliver high current income and attractive total
returns over time while seeking to cushion the volatility inherent in this
market.

MANAGEMENT'S DISCUSSION OF THE FUND PERFORMANCE

GROWTH EQUITY FUND

For several years now we have focused on our modest expectations for the
financial markets in the upcoming twelve months. While we understood and
generally identified the forces that would enable the stock market to continue
its advance, it was difficult to fully anticipate the ability of these factors
to drive that market ahead as strongly as they have. Rapid technological change
and its acceptance have transformed our economy and our financial markets at a
mind-boggling pace.

Consider the Internet. It began as a way for scientists and researchers to share
information, moved on to be a vehicle for email, homework help and an
alternative to catalog shopping, and has now gone "B2B" and is a critical factor
in much of corporate strategic planning. Similarly, technology-driven advances
in traditional pharmaceuticals and genetically derived biopharmaceuticals,
medical instruments and equipment, and the delivery and management of health
care are transforming society in ways we are only beginning to fathom. And,
finally, dramatic changes in telecommunications continue to draw the world
closer together. The aggregate impact of how individuals, companies, and
governments utilize and embrace these and related opportunities and challenges
will have a great deal to do with how much longer and further this economic
expansion and its derivative stock market advance can carry.

The fourth quarter of 1999 was an especially rewarding one for the Penn Series
Growth Equity Fund. For the quarter the Fund returned 27.93% which was decidedly
better than its traditional benchmarks of the S&P 500 Index (14.94%), the S&P
500/BARRA Growth Index (19.74%) and the Lipper Growth Fund Average (21.20%). The
Fund also managed to outperform the new Lipper Large Cap Growth Index that
returned 25.54% for the three-month period.

As a result of the strong fourth quarter the Growth Equity Fund was propelled to
a full year's performance that again bested its traditional benchmarks. With a
return of 34.10% for all of 1999 the Fund outpaced the 21.03%, 28.26% and 29.27%
returns for the S&P 500 Index, the S&P 500/BARRA Growth Index and the Lipper
Growth Fund Average, respectively. The new Lipper Large Cap Growth Index
slightly outperformed the Fund with a return of 34.82%.

For the three year period just ended the Penn Series Growth Equity fund produced
an annualized return of 34.03% versus 27.55% for the S&P 500, 35.53% for the S&P
500/BARRA Growth Index and 32.90% for the new Lipper Large Cap Growth Index.

This past year again saw the market differentiated along growth and value lines
with growth strongly outperforming value. For all of 1999 the Russell 1000
Growth Index produced a return of 33.16% while its Value counterpart returned
only 7.35%. The Technology sector contributed the most to the Fund's performance
during the year, followed by the Consumer Cyclical sector. Reflective of a very
narrow market in 1999 no other sector contributed meaningfully to the Fund's
performance for the full year.

Once again the characteristics of the Fund's holdings demonstrate a commitment
to investing in those companies generating consistent and sustainable earnings
and sales growth. By applying our disciplined analysis and evaluation to
reported and forecast earnings trends for individual companies we have been able
to maintain a significant edge in identifying firms that do produce positive
earnings surprises and subsequently report growth at rates above historical
trends. Growth remains most robust among select technology, communication
services, consumer cyclical, and financial service companies.

Among the Fund's largest holdings as of December 31st were Microsoft, Cisco
Systems, General Electric, Home Depot, Texas Instruments, Qualcomm, Citigroup,
and Sun Microsystems.

OUTLOOK

As we enter 2000 it is difficult to envision an impending end to what will be,
as of February, this nation's longest-running economic expansion. By most
accounts, economists agree with that assumption given their estimates of real
GDP growth generally running from 3% to 5% or so. Few, if any, are calling for
negative real growth during any quarter this year. Most continue to forecast
reasonable profit growth this year with estimates running from 8% to 15%.
Finally, and perhaps most importantly, the majority of economists continue to
look for inflation to remain subdued at around the 2% to 2 1/2% level this year.

Yet despite the forecast for more good news on inflation, the consensus
viewpoint is that the Federal Reserve will raise rates during the first quarter
of 2000, and possibly again in the second quarter in response to the economy's
continued strength and low unemployment rate. What are the Federal Reserve's
concerns? Recently the Fed stated that, "Based on the available evidence (it)
remains concerned with the possibility that over time increases in demand will
continue to exceed the growth in potential supply, even after taking account of
the remarkable rise in productivity growth. Such trends could foster
inflationary imbalances that would undermine the economy's exemplary
performance."

<PAGE>


In its efforts to steer the economy toward another soft landing the Fed is
clearly caught between its reliance on traditional economic thinking which sees
a direct correlation between reduced unemployment and higher inflation and its
grudging acceptance of something akin to a new economic dynamic that is an
outgrowth of the economy's technology-created productivity improvement. A
significant portion of the market's volatility this year can be attributed to
the Fed's split personality that has manifested itself in often-contradictory
statements by many of its members. To some degree the bond market and the stock
market also reflect this dichotomy. The bond market's rising rates reflect an
"old" economy response to the strong economy while the stock market's rise,
which has been led by the technology sector and continues to generally ignore
the bond market, speaks to an embracing of "new" economy themes.

We have embraced those themes for sometime now and see no reason to retreat
despite the stock market's late year climb. Most of the benefits of the
technology-driven economy lie ahead and the stock market understands this. We
expect that any corrections over the course of the year will be short-lived and
will most likely be the result of some Fed action that surprises the market.
Obviously, the more active or vocal the Fed is in 2000 the more volatile the
financial markets will likely be. On balance we see the overall trend of the
stock market remaining positive, but would not expect returns to match those of
the past several years. Technology might again do well, but the market should
also see a broadening of participation as other sectors will look comparatively
more attractive.

PENN SERIES FUNDS, INC.
MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

VALUE EQUITY FUND

The stock market continued to advance strongly in 1999 in a favorable
environment of sustained economic growth with low inflation. The S&P 500 Index
rose 21.0%, returning more than 20% for a record fifth consecutive year.
However, even as the popular indexes kept hitting new highs, the market was
characterized by two contradictory trends: the rapid escalation of technology
stocks, especially those associated with the Internet and e-commerce, and the
only modest gains or even price declines for many stocks in other industry
sectors.


Despite the sizable gain of the S&P 500, fully one-third of the stocks on the
New York Stock Exchange declined 20% or more in 1999. Even stocks of non-tech
companies with excellent competitive positions and strong cash flow , the types
of stocks owned by the Fund, tended to fare poorly in this technology-focused
market. As a result, the Fund's negative return of 0.8% trailed the S&P 500.

The Fund owns an eclectic group of stocks that we believe have superior earnings
and cash flow prospects and are undervalued in relation to these prospects. Some
of the stocks, which contributed to the Fund's performance in 1999, included
Computer Associates (computer software), Citigroup (financial services) and
Minnesota Mining (diversified technology-based company). Stocks which detracted
from performance included Freddie Mac (mortgage insurance) and Kroger (grocery
store chain).

The U.S. economy remains strong, perhaps too strong, and there are indications
of excessive optimism in the stock market. Inflation has been kept low for the
past several years by an internationally competitive environment, major
improvements in technology, continued mergers and restructurings, and low
inflation expectations. Recently, however, some of these factors have reversed.
Commodity prices have rebounded strongly, while energy and import prices are on
the rise. These factors suggest to us that inflationary pressures could increase
somewhat in the months ahead and that the Federal Reserve is likely to raise
interest rates further, on top of the three rate increases already implemented
since June 1999.

We think these conditions will favor our value style of investing, which
emphasizes companies that can generate a high level of cash flow throughout the
economic cycle. By investing in these companies and remaining disciplined in our
value style, we are focused on delivering excellent long-term investment results
while controlling risk.

PENN SERIES FUNDS, INC.
MANAGEMENT'S DISCUSSION OF THE FUND PERFORMANCE

FLEXIBLY MANAGED FUND

From the view of most investors, the year, decade, century, and millennium
closed with a bang. Propelled by a narrow but powerful rally in technology
stocks - especially those connected in any way with the Internet -- the bull
market stormed into the future. The broad market as measured by the S&P 500
Stock Index recorded an unprecedented fifth straight year of gains over 20%, but
the average stock in the index substantially underperformed. A notable feature
of last year's market was that stocks surged despite a significant rise in
interest rates and resulting weakness in the bond market.

In a market driven by investors focusing almost exclusively on opportunities for
return rather than potential for risk, funds like this one that emphasize
diversification, value, and risk avoidance were left far behind. Our returns for
the year were positive at 7.15% but anemic next to those chalked up by broad
market indices and growth-oriented funds as measured by the 21.04% return for
the S&P 500.

Our asset allocation changed little over the course of 1999, ending the year
with about 55% in common stocks, 25% in convertible securities, 12% in bonds, 1%
in preferred stocks, and the remainder in reserves. One of our largest sectors,
consumer services, was also one of the best-performing, thanks mainly to strong
contributions from media stocks such as the New York Times. Energy, another
sizable sector in the fund, also provided positive results, particularly
Mitchell Energy & Development, Kerr-McGee, Amerada Hess, and Murphy Oil. In the
process industries area, MacMillan Bloedel (now merged into Weyerhaeuser) was a
standout, as was Domtar. Unfortunately, another large exposure of the fund,
utilities, performed poorly in the rising interest rate environment.

Major disappointments for the year included Loews, a diversified holding
company, and Philip Morris, hurt by continued tobacco litigation. Nevertheless,
we see much value in these beaten-down shares and may add to them in the future,
as well as to Rouse, a REIT with major shopping mall holdings. Our substantial
investment in Tennessee Valley Authority bonds was not rewarding last year,
although they held up much better than other government agency bonds because of
their unique features. Given the potential for further interest rate hikes by
the Federal Reserve, we are pondering this TVA position.

We are generally optimistic about the portfolio, since our holdings are cheap
and the underlying companies have significant value. Our bonds and convertibles
meet rational criteria designed to maximize returns over time versus the risks
we take. All wild bull markets come to an end, some in a painful fashion. When
the pendulum swings, this conservative portfolio will still be here seeking to
help investors increase their wealth with minimal risk.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

INTERNATIONAL EQUITY FUND


In 1999, Japan's recovery led Asia out of an economic slump that had lasted for
the last several years. The surging yen and the sustained growth in the equity
market suggest that real restructurings and subsequent recovery have taken a
firm foothold in Japan.

There has been a crucial change in Japan and the rest of Asia regarding the
creation of shareholder value. There have been multiple announcements recently
of mega jont ventures, and older traditional systems of valuation, particularly
in the banking sector, are being phased out in favor of using ROE as the primary
benchmark to measure the firm's success, as is currently being done in the U.S.

The convenience store chain Seven Eleven Japan was added to the portfolio during
the fourth quarter. The franchise boasts a 15-year track record of consistent
returns and a balance sheet with no debt. Other new additions in Japan included
Ryohin Keikaku, a leading retail chain, Secom, a security service firm, and
Asatsu-DK, a market leader in adverstising which has given employees equity
ownership, a practice which is still somewhat unique in Japan. These firms share
the qualities of being leaders in their respective industries, supported by
rising operating margins.

Japan was the best performing EAFE market in 1999, and our exposure to Japan
added to performance, with many of our long-term core holdings, such as Murata
and Rohm, providing returns upto 40%. Stocks such as NTT Docomo and Hikara
Tsushin provided lucrative exposure to the fast-growing mobile
telecommunications market in Japan, and they present excellent investment
opportunities.

One year after the introduction of the Euro currency, there is clear evidence
that the European Union is working well as a unified organization, and that the
Euro-11 has not fallen prey to purely French or German political interests.

There was a significant amount of cross-border merger activity in Europe in
1999, as the Euro-11 solidified. Romano Prodi, the Italian president of The
European Commision, has not opposed any cross-border M&A activity. The Vodafone
- - Mannesmann merger represented the biggest cross-border acquisition ever seen
in Europe, and companies increasingly face the risk of being taken over. As the
European equity market matures, company management has begun increasingly to
recognize the importance of generating better returns for shareholders. This was
evidenced by the large number of share cancellations and share buy-backs that
will boost earnings for many companies across Europe.

In December of 1999, the Euro passed the psychological barrier of parity with
the US Dollar, although it was bolstered by the end of the day's trading so as
not to close at a rate less than the dollar. While the declining Euro may have
had negative political connotations, the economic impact has been positive for
European businesses, which have benefited from the weaker Euro in many export
markets.

Stock picking in Europe had a positive impact on returns. Many of our European
holdings, such as Mannesmann and Vodafone, provided returns well in excess of
20% for the year. Telecom stocks performed extraordinarily well and our holdings
exceeded expectations. Our weighting of over 10% in European telecomm paid off
nicely in 1999. Hedges against the Euro which were placed at various points
throughout the year had a net positive impact on returns. The portfolio's
overweight to Europe versus Asia was a liability in the third quarter. In the
Fourth quarter, however, we benefited from Europe's recovery, as the European
overweight had a net positive effect on fourth quarter performance.

PENN SERIES FUNDS, INC.
MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

SMALL CAPITALIZATION FUND


Small cap value stocks were an overlooked segment of the stock market in 1999.
While many large cap and technology issues rose sharply, the Russell 2000 Value
Index actually declined 1.5% during the year. In comparison to this decline, and
in comparison to the 21.3% return of the Russell 2000 Index (a small cap
benchmark which includes both value and growth stocks), the Fund's negative
return was 1.33%. Growth stocks include those projected to have steady earnings
increases, while value stocks include those that are believed to be
significantly underpriced in relation to their inherent value.

Some of the stocks that contributed positively to our performance in the fourth
quarter of 1999 included:

*    General Semiconductor, an electronic component supplier, experienced a
     pickup in volume and improved pricing as the Asian economic crisis
     subsided.

*    Harman International, which produces high-fidelity audio products,
     benefited from a rationalized capital structure and significant new
     business from automobile original equipment manufacturers and personal
     computer manufacturers.

*    Cambrex Corporation, which supplies products and services for the
     pharmaceutical and biotechnology industries, benefited from the continued
     growth of its markets.

*    Air Express, an international airfreight forwarder and provider of global
     logistics services for importers and exporters, was acquired by Deutche
     Post.

Investments that detracted most from performance in the quarter included:

*    AmeriSource, a wholesale distributor of pharmaceutical products and related
     health care services, declined due to investor concerns about possible
     government controls on pharmaceutical pricing, as well as concerns about
     the competitive impact of new Internet-based drugstores. The company also
     slightly missed its earnings per share estimates. We added to our position
     in the belief that these concerns are overstated and the stock is
     inexpensive in relation to the company's earnings and cash flow prospects.

*    BMC Industries, a producer of aperture masks, ophthalmic lenses and
     photo-etched metal and electroformed parts, reported lower earnings due to
     the poor results of an acquired company.

*    Shopko, a specialty discount retailer, was down in the quarter due to the
     general disfavor of retailing stocks. We think the share price is
     inexpensive and added to our holdings.

*    Policy Management Systems, which provides enterprise software and
     electronic commerce systems to financial service companies, experienced an
     earnings shortfall in the fourth quarter as customers delayed new software
     purchases to focus on resolving Y2K problems.

Because they have underperformed the overall stock market for an extended
period, we believe there are many opportunities at this time to purchase quality
small cap value stocks inexpensively. We remain confident that the market will
recognize these values over time and that the Fund will deliver excellent
long-term investment results with below-market risk.

PENN SERIES FUNDS, INC.
MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

EMERGING GROWTH FUND


We concluded a memorable year of performance in 1999 with very strong 4th
quarter performance, as investors flocked to fast growth stocks in both the
Russell 2000 Growth and the NASDAQ indices.

The Penn Series Emerging Growth Portfolio rose 76.17% in the fourth quarter,
against a gain of 33.39% in the benchmark Russell 2000 Growth. We managed to
outperform the benchmark in every quarter this year, leading to a calendar year
return of 185.03% for the Penn Series Emerging Growth Portfolio, against a
43.09% rise in the Russell 2000 Growth.

Investors' interest in small stocks broadened in the fourth quarter, fueling the
strong rally in the Russell 2000 Growth. In the fourth quarter, eight of the 11
Russell sectors produced positive performance. While we continued to emphasize
technology, our results were bolstered by strong performance from other sectors
as well.

We enjoyed strong returns from a number of stocks in the healthcare sector where
technology is merging into traditional healthcare and biotech to create emerging
growth investment opportunities. The focus of much of this new work is towards
prediction and prevention of illness rather than the traditional detection and
treatment of disease. Companies like Medarex Incorporated and Abgenix, Inc. are
pioneering new techniques in applying the study of DNA within a technology
framework. Typically these companies work closely with large drug companies to
accelerate their research and testing capabilities as the drug companies look to
create and rollout the next blockbuster drug.

Cytyc Corporation has applied new technology to cervical cancer screening.
Historically this test has had a high margin of error. Cytyc has introduced a
new technology that has made their version of the test more dependable. This
enhanced reliability has made Cytyc's ThinPrep System very popular among
healthcare providers. In turn, most HMO's are now providing partial or full
reimbursement on the ThinPrep Test, helping to fuel it's growth in the
marketplace.

We began accumulating the stock in late spring of this year when the stock was
reasonably undiscovered and had a market capitalization under $500 million.
Since then Cytyc has announced triple digit revenue and earnings increases for
the last two quarters, dramatically increasing visibility of the companies
fundamental story. The stock has moved up strongly in the third and fourth
quarters, finishing the year with a market cap over $1 billion.

Investor's appetite for fast growing stocks that are powering technology growth
seemed nearly insatiable in the 4th quarter. The tech heavy NASDAQ rose 48.18%
in the fourth quarter alone! Gains in technology stocks also drove the strong
33.39% return in the benchmark, the Russell 2000 Growth. This strong performance
also helped to expand the technology sector weighting of the Russell 2000 Growth
from 22% at the beginning of the year to 34% at year-end.

Throughout the fourth quarter we maintained our yearlong emphasis on technology
companies. We continue to find many exciting companies that are creating change
in various sectors of the economy including telecommunications, media, hardware,
software, and above all, how businesses leverage the Internet.

Forrester Research estimates the market for internet and e-commerce services to
grow from $5.4 billion in 1998 to $32.7 billion in 2002, creating a business
opportunity with a compounded annual growth rate of 57%. The struggle for most
traditional, large companies is how to make their business more Web friendly,
and then how to integrate these new internet based applications with their
existing "legacy" systems. The supply of systems professionals with these
technical skills is constrained, and corporate America is thin on this
expertise. This creates a major opportunity for small, fast moving consulting
firms to fill the void.

We owned a broad number of companies that provide internet system integration
and consulting services. Earlier in the year, we sensed that Fortune 1000
companies would spend significantly and quickly to get Internet capabilities
built. We took significant positions in companies like Sapient Corporation. We
have known these companies for a long time and believe they are well positioned
to gain in this internet spending race. We also invested in newcomers like
Proxicom, Scient Corporation, and Viant and were rewarded with strong
performance through the third and fourth quarters from these stocks as well.

Many of the stocks came public this year. We often participated in the Initial
Public Offering of these companies, and added to our positions over time.
Valuation of these stocks is not easy as the companies have short operating
histories, and valuations based on revenue multiples accelerated quickly.
Nonetheless, we developed metrics based on factors such as gross margins,

<PAGE>

revenue per billable personnel, average engagement size, and sales force growth
and productivity. In addition we found it useful to build our own, more
realistic revenue and earnings models rather than rely solely on Street models,
which we find are often built to focus on large quarterly outperformance.

Nearly all the stocks have produced meaningful returns to the portfolio, as
investors have been attracted to the companies rapid revenue growth opportunity,
and as investors seeking internet exposure rotated out of more consumer based
internet investment opportunities.

1999 was a banner year for IPO volume as more than $75 billion (though mid
December) of new equity was issued, surpassing the previous record set in 1997.
We aggressively mined the IPO universe for new Emerging Growth investment
supply, participating in over 150 IPOs in calendar 1999. And we held onto many
of these issues as we continued our research process on the companies as they
matured. Interestingly, the IPO position's impact on performance was not that
significant. We calculate that IPOs contributed only about 41 percentage points,
or roughly 22%, out of the portfolio's 182% total return for 1999.

Two of our largest contributors to return, Network Solutions and Knight/Trimark
Group, were companies that came public in 1997 and 1998. We participated in
those companies IPOs and had built a strong knowledge base on the companies,
giving us the edge to own them in a meaningful way in 1999. This provides a
confirmation that our emerging growth research process pays off for investors
over time.

While we enjoyed a banner year in 1999, we remain optimistic as we enter a new
year. At the fundamental level, we see many companies with very compelling
growth opportunities, and with the capabilities in place to succeed in their
respective market. The volume of IPO's has provided us ample supply of
investment ideas. However, we are somewhat concerned about the flood of investor
money into this emerging growth space. It is reasonable to expect continued
volatility. As always, we will seek to take advantage of these periods of
volatility to improve the portfolio for the long term.

We appreciate your confidence in our effort and are very pleased to have you as
a client.

PENN SERIES FUNDS, INC.
NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 1999
- --------------------------------------------------------------------------------

1 -- SIGNIFICANT ACCOUNTING POLICIES

   Penn Series Funds, Inc. (Penn Series) was incorporated in Maryland on April
22, 1982. Penn Series is registered under the Investment Company Act of 1940, as
amended, as an open-end, diversified management investment company.

   Penn Series is presently offering shares in its Money Market, Quality Bond,
High Yield Bond, Growth Equity, Value Equity, Flexibly Managed, International
Equity, Small Capitalization and Emerging Growth Funds (the Funds). It is
authorized under its Articles of Incorporation to issue a separate class of
shares in one additional fund. The Fund would have its own investment objective
and policy.

   The following is a summary of significant accounting policies followed by
Penn Series in the preparation of its financial statements. 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. Actual results could differ
from those estimates.

   INVESTMENT VALUATION:

   Money Market Fund -- Investments in securities are valued under the amortized
cost method, which approximates current market value. Under this method,
securities are valued at cost on the date of purchase and thereafter a
proportionate amortization of any discount or premium until maturity is assumed.
Penn Series maintains a dollar weighted average portfolio maturity appropriate
to the objective of maintaining a stable net asset value per share. The Penn
Series Board of Directors (the Board) has established procedures reasonably
designed to stabilize the net asset value per share for purposes of sales and
redemptions at $1.00. The Board performs regular review and monitoring of the
valuation in an attempt to avoid dilution or unfair results to shareholders.

   Quality Bond, High Yield Bond, Growth Equity, Value Equity, Flexibly Managed,
International Equity, Small Capitalization and Emerging Growth Funds --
Portfolio securities listed on a national securities exchange are valued at the
last sale price on the securities exchange or securities market on which such
securities primarily are traded or, if there has been no sale on that day, at
the mean between the current closing bid and asked prices. All other securities
for which over-the-counter market quotations are readily available will be
valued on the basis of the mean between the last current bid and asked prices.
When market quotation are not readily available, or when restricted or other
assets are being valued, the securities or assets will be valued at fair value
as determined by the Board.

   The high yield securities in which the High Yield Bond Fund may invest are
predominantly speculative as to the issuer's continuing ability to meet
principal and interest payments. The value of the lower quality securities in
which the High Yield Bond Fund may invest will be affected by the credit
worthiness of individual issuers, general economic and specific industry
conditions, and will fluctuate inversely with changes in interest rates. In
addition, the secondary trading market for lower quality bonds may be less
active and less liquid than the trading market for higher quality bonds.

   Foreign Currency Translation -- The books and records of the Funds are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis: market value of investment securities, assets
and liabilities at the current rate of exchange, purchases and sales of
investment securities, income and expenses at the relevant rates of exchange
prevailing on the respective dates of such transactions.

   The Funds do not isolate the portion of realized and unrealized gains and
losses on investments which is due to changes in the foreign exchange rate from
that which is due to changes in market prices of equity securities. Such
fluctuations are included with net realized and unrealized gain or loss from
investments.

   Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of U.S. dollar denominated
transactions as a result of, among other factors, the level of governmental
supervision and regulation of foreign securities markets and the possibility of
political or economic instability.

   SECURITY TRANSACTIONS AND INVESTMENT INCOME: Security transactions are
accounted for on the trade date. Dividend income is recorded on the ex-dividend
date and interest income is accrued as earned. The cost of investment securities
sold is determined by using the specific identification method for both
financial reporting and income tax purposes.

   DIVIDENDS TO SHAREHOLDERS: Dividends of investment income and realized
capital gains of the Quality Bond, High Yield Bond, Growth Equity, Value Equity,
Flexibly Managed, International Equity, Small Capitalization and Emerging Growth
Funds will be declared and paid within 30 days of the Funds' year end, December
31, as permitted by federal income tax regulations. Dividends of net investment
income of the Money Market Fund are declared daily and paid monthly.

      Dividends from net investment income and distributions from net realized
gains are determined in accordance with federal income tax regulations which may
differ from net investment income and net realized capital gains recorded in
accordance with generally accepted accounting principles. To the extent these
differences are permanent, such amounts are reclassified within the capital
accounts based on their federal tax basis treatment; temporary differences do
not require such reclassification. Distributions from net realized gains for
book purposes may involve short-term capital gains, which are included as
ordinary income for tax purposes.

PENN SERIES FUNDS, INC.
NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 1999 (Continued)
- --------------------------------------------------------------------------------

FEDERAL INCOME TAXES: The Funds intend to continue to qualify as regulated
investment companies under Subchapter M of the Internal Revenue code and to
distribute all of their taxable income, including realized gains, to their
shareholders. Therefore, no federal income tax provision is required.

2 -- DERIVATIVE FINANCIAL INSTRUMENTS

Off-Balance Sheet Risk

   The Funds may trade financial instruments with off-balance sheet risk in the
normal course of investing activities and to assist in managing exposure to
market risks such as interest rates and foreign currency exchange rates. These
financial instruments include written options, forward foreign currency exchange
contracts and futures contracts.

   The notional or contractual amounts of these instruments represent the
investment the Funds have in particular classes of financial instruments and do
not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only
when all related and offsetting transaction are considered.

Derivative Financial Instruments Held or Issued for Purposes Other Than
Trading

   Futures Contracts -- Each of the Funds, other than Money Market, may enter
into financial futures contracts for the delayed delivery of securities,
currency or contracts based on financial indices on a future date. A Fund is
required to deposit either in cash or securities an amount equal to a certain
percentage of the contract amount. Subsequent payments are made or received by a
Fund each day, dependent on daily fluctuations in the value of the underlying
security, and are recorded for financial statement purposes as unrealized gains
or losses by a Fund. A Fund's investment in financial futures contracts is
designed only to hedge against anticipated future changes in interest or
exchange rates. Should interest or exchange rates move unexpectedly, a Fund may
not achieve the anticipated benefits of the financial futures contracts and may
realize a loss. The Quality Bond Fund has entered into futures contracts during
the year ended December 31, 1999. There were no open futures contracts at
December 31, 1999.

   Options -- Each of the Funds, other than Money Market, may write covered
calls. Additionally, each of the Funds may buy put or call options for which
premiums are paid whether or not the option is exercised. Premiums received from
writing options, which expire, are treated as realized gains. Premiums received
from writing options, which are exercised or are closed are offset against the
proceeds or amount paid on the transaction to determine the realized gain or
loss. If a put option is exercised the premium increases the cost basis of the
securities purchased by a Fund. As writer of an option, the Fund may have no
control over whether the underlying securities may be sold (call) and, as a
result, bears the market risk of an unfavorable change in the price of the
securities underlying the written option. The Flexibly Managed Fund has entered
into put and call options during the year ended December 31, 1999. Purchased put
and call options open and outstanding at December 31, 1999 are disclosed in the
statement of net assets. Losses on options written during the year ended
December 31, 1999 of $411,819 have been included with those from investment
transactions on the Statement of Operations.

   Forward Foreign Currency Contracts -- The Funds may enter into forward
foreign currency exchange contracts as a way of managing foreign exchange rate
risk. A Fund may enter into these contracts to fix the U.S. dollar value of a
security that it has agreed to buy or sell for the period between the date the
trade was entered into and the date the security is delivered and paid for. A
Fund may also use these contracts to hedge the U.S. dollar value of securities
it already owns denominated in foreign currencies.

   Forward foreign currency contracts are valued at the forward rate, and are
marked-to-market daily. The change in market value is recorded by the Fund as an
unrealized gain or loss. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of the contract
at the time it was opened and the value at the time it was closed.

   The use of forward foreign currency contracts does not eliminate fluctuations
in the underlying prices of the Fund's portfolio securities, but it does
establish a rate of exchange that can be achieved in the future. Although
forward foreign currency contracts limit the risk of loss due to a decline in
the value of the hedged currency, they also limit any potential gain that might
result should the value of the currency increase. In addition, the Funds could
be exposed to risks if the counterparties to the contracts are unable to meet
the terms of their contracts. The High Yield Bond, Flexibly Managed and
International Equity Funds have entered into forward foreign currency contracts
during the year ended December 31, 1999. At December 31, 1999 there were no open
contracts in the High Yield Bond, Flexibly Managed and International Equity
Funds.

years in the period then ended and the financial highlights for each of the
three years in the period then ended. 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. The financial highlights of Penn Series Funds, Inc. for the

other auditors whose report dated February 11, 1997, expressed an unqualified
opinion on those financial highlights

We conducted our audits in accordance with auditing standards generally accepted

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 and financial highlights. Our procedures included
confirmation of securities owned as of December 31, 1999, by correspondence with
the custodians and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial presentation. We believe our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
