                      (Unaudited)

     NOTES  TO  CONSOLIDATED  FINANCIAL  STATEMENTS

1  -  Basis  of  Presentation

     The  financial  information  for  the  interim  periods  included herein is
unaudited;  however,  such  information  reflects all adjustments, consisting of
normal recurring adjustments, which are, in the opinion of management, necessary
to  a  fair  presentation  of the financial position, results of operations, and
cash  flows  for  the  interim  periods.  The  results of operations for interim
periods  are  not  necessarily indicative of results to be expected for the full
year.

     These financial statements should be read in conjunction with the financial
statements  and  notes  for  the  year  ended  December 31, 2002 included in the
Company's  2002  Annual Report filed with the Securities and Exchange Commission
on  Form  10-K.

     The  affiliate  transaction  disclosures  on  the  face  of  the  financial
statements  are  in  regards  to transactions with Harleysville Mutual Insurance
Company (Mutual).  Mutual owns approximately 56% of the outstanding common stock
of  Harleysville  Group  Inc.  As  used  herein,  "Harleysville Group" refers to
Harleysville  Group  Inc.  and  its  subsidiaries.

Policy  Acquisition  Costs

     Policy  acquisition  costs,  such as commissions, premium taxes and certain
other  underwriting and agency expenses that vary with, and are directly related
to,  the  production  of business, are deferred and amortized over the effective
period  of  the related insurance policies in proportion to the premiums earned.
The  method  followed  in computing deferred policy acquisition costs limits the
amount  of  such  deferred  costs  to  their  estimated  realizable  value.  The
estimation  of net realizable value takes into account the premium to be earned,
related  investment  income  over  the  claims  paying  period,  losses and loss
settlement  expenses,  and  certain  other  costs expected to be incurred as the
premium  is  earned.  Future changes in estimates, the most significant of which
is  expected  losses  and  loss  settlement expenses, may require adjustments to
deferred  policy  acquisition  costs.  If the estimation of net realizable value
indicates  that  the  acquisition  costs are unrecoverable, further analyses are
completed  to  determine if a reserve is required to provide for losses that may
exceed  the  related  unearned  premiums.

Stock-Based  Compensation

     Stock-based  compensation  plans  are accounted for under the provisions of
Accounting  Principles  Board  (APB)  Opinion  No.  25,

"Accounting  for  Stock  Issued  to  Employees,"  and  related  interpretations.
Accordingly, no compensation expense is recognized for fixed stock option grants
and  an  employee stock purchase plan. Compensation expense would be recorded on
the  date  of  a  stock  option  grant  only  if the current market price of the
underlying  stock  exceeded the exercise price.  The following table illustrates
the  effect  on  net  income  and  earnings  per  share  as if the provisions of
statement  of  Financial Accounting Standards (SFAS) No. 123 (as amended by SFAS
No.  148),  "Accounting  for Stock-Based Compensation," had been applied for the
three  and  nine  months  ended  September  30,  2003  and  2002:

2003,  respectively,  because  their  inclusion  would  have had an antidilutive
effect.

3  -  Reinsurance

     Premiums earned are net of amounts ceded of $17,129,000 and $51,589,000 for
the  three  and  nine  months  ended  September  30,  2003,  respectively,  and
$17,139,000  and  $50,601,000  for the three and nine months ended September 30,
2002,  respectively.  Losses  and  loss  settlement  expenses are net of amounts
ceded  of  $57,228,000  and  $94,734,000  for  the  three  and nine months ended
September  30, 2003, respectively, and $10,008,000 and $26,054,000 for the three
and  nine  months  ended  September 30, 2002, respectively.  Such amounts do not
include  the reinsurance transactions with Harleysville Mutual Insurance Company
(Mutual) under the pooling arrangement, but do include the reinsurance described
in  the  following  paragraph.  Of the losses and loss settlement expenses ceded
for the three months ended September 30, 2003, $53.7 million is for losses ceded
to  involuntary reinsurance mechanisms and reflect increased estimates of losses
on lifetime medical cases.  Of this $53.7 million, $48.7 million is ceded to the
Michigan  Catastrophic  Claims  Association  (MCCA)  which covers no-fault first
party medical losses in excess of a retention ranging from $250,000 to $325,000.
Since these ceded losses are above the retention, the increased estimates had no
net  impact  on  results  of  operations.

     Harleysville  Group  has a reinsurance agreement with Mutual whereby Mutual
reinsures  accumulated  catastrophe  losses  in  a  quarter up to $14,400,000 in
excess  of  $3,600,000  in  return  for  a  reinsurance  premium.  The agreement
excludes catastrophe losses resulting from earthquakes, terrorism or hurricanes,
and  supplements  the  existing  external  catastrophe  reinsurance  program.
Harleysville  Group ceded to Mutual premiums earned of $2,108,000 and $1,996,000
and  losses  incurred  of  $(140,000)  and  $213,000  for the three months ended
September  30,  2003  and 2002, respectively. Harleysville Group ceded to Mutual
premiums  earned  of $6,348,000 and $5,859,000 and losses incurred of $4,634,000
and  $279,000  for  the  nine  months  ended  September  30,  2003  and  2002,
respectively.

     Pursuant  to the terms of a reinsurance pooling agreement with Mutual, each
of  the insurance subsidiaries of Harleysville Group Inc. cedes premiums, losses
and  expenses  on  all  of  their  respective business to Mutual which, in turn,
retrocedes  to  such  subsidiaries  a  specified portion of premiums, losses and
expenses  of  Mutual  and  such  subsidiaries.  Because  this agreement does not
relieve Harleysville Group Inc.'s insurance subsidiaries of primary liability as
originating  insurers,  there  is  a  concentration  of credit risk arising from
business  ceded  to

Mutual.  However,  the  reinsurance  pooling agreement provides for the right of
offset.  Mutual  has  an  A.  M.  Best  rating  of  "A"  (Excellent).


4  -  Cash  Flows

     Net  cash  tax payments of $1,096,000 and $8,750,000 were made in the first
nine months of 2003 and 2002, respectively. Cash interest payments of $2,817,000
and  $2,927,000  were  made  in  the  first  nine  months  of  2003  and  2002,
respectively.

7  -  Shareholders'  Equity

     Various  states  have  adopted  the  National  Association  of  Insurance
Commissioners  (NAIC)  risk-based capital (RBC) standards that require insurance
companies to calculate and report statutory capital and surplus needs based on a
formula  measuring underwriting, investment and other business risks inherent in
an  individual  company's operations.  These RBC standards have not affected the
operations  of  Harleysville  Group  since  each  of  the  Company's  insurance
subsidiaries  has  statutory  capital and surplus in excess of RBC requirements.

     NOTES  TO  CONSOLIDATED  FINANCIAL  STATEMENTS
                     (Continued)

     These  RBC  standards  require the calculation of a ratio of total adjusted
capital  to  Authorized  Control  Level.  Insurers  with  a ratio below 200% are
subject  to  different levels of regulatory intervention and action.  Based upon
their  2002  statutory financial statements, the ratio of total adjusted capital
to the Authorized Control Level for the Company's nine insurance subsidiaries at
December  31,  2002  ranged  from  642%  to  812%.

     In  July  2003,  the Company issued $100 million of 5.75% notes payable due

ITEM  2.   MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  RESULTS
                OF  OPERATIONS  AND  FINANCIAL  CONDITION

     Certain  of  the  statements  contained  herein  (other  than statements of
historical  facts)  are  forward  looking  statements.  Such  forward  looking
statements  are  made  pursuant  to  the  safe  harbor provisions of the Private
Securities  Litigation  Reform Act of 1995 and include estimates and assumptions
related  to  economic,  competitive  and legislative developments. These forward
looking  statements  are  subject  to  change and uncertainty which are, in many
instances,  beyond  the  Company's  control  and  have  been  made  based  upon
management's  expectations  and beliefs concerning future developments and their
potential  effect  on  Harleysville Group. There can be no assurance that future
developments  will  be  in accordance with management's expectations so that the
effect of future developments on Harleysville Group will be those anticipated by
management.  Actual  financial results including premium growth and underwriting
results  could  differ  materially  from those anticipated by Harleysville Group
depending  on  the  outcome  of  certain  factors,  which may include changes in
property  and casualty loss trends and reserves; catastrophe losses; competition
in  insurance  product  pricing; government regulation and changes therein which
may  impede  the  ability to charge adequate rates; performance of the financial
markets;  fluctuations in interest rates; availability and price of reinsurance;
and  the  status  of  labor  markets  in  which  the  Company  operates.


Critical  Accounting  Policies  and  Estimates

     The  consolidated  financial  statements  are  prepared  in conformity with
accounting  principles generally accepted in the United States of America, which
require  Harleysville Group to make estimates and assumptions (see Note 1 of the
Notes  to Consolidated Financial Statements for the year ended December 31, 2002
included  in  the  Company's  2002  Annual  Report filed with the Securities and
Exchange  Commission  on  Form  10-K).  Harleysville  Group believes that of its
significant  accounting  policies,  the following may involve a higher degree of
judgment  and  estimation.

     Liabilities  for  Losses  and  Loss Settlement Expenses.  The liability for
losses  and loss settlement expenses represents estimates of the ultimate unpaid
cost of all losses incurred, including losses for claims which have not yet been
reported to Harleysville Group.  The amount of loss reserves for reported claims
is  based primarily upon a case-by-case evaluation of the type of risk involved,
knowledge  of  the circumstances surrounding each claim and the insurance policy
provisions  relating  to  the

Page  15


         HARLEYSVILLE  GROUP  INC.  AND  SUBSIDIARIES

     MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  RESULTS
          OF  OPERATIONS  AND  FINANCIAL  CONDITION
                      (Continued)

type  of  loss.  The  amounts  of  loss  reserves for unreported claims and loss
settlement  expense  reserves are determined utilizing historical information by
line  of  insurance  as adjusted to current conditions.  Inflation is implicitly
provided  for  in  the  reserving function through analysis of costs, trends and
reviews of historical reserving results.  Reserves are closely monitored and are
recomputed periodically using the most recent information on reported claims and
a variety of statistical techniques.  It is expected that such estimates will be
more  or  less  than  the  amounts  ultimately paid when the claims are settled.
Changes  in  these  estimates  are  reflected  in  current  operations.

     Investments.  Generally,  unrealized  investment  gains  or  losses  on
investments carried at fair value, net of applicable income taxes, are reflected
directly  in  shareholders'  equity  as a component of comprehensive income and,
accordingly,  have  no  effect  on net income.  However, if the fair value of an
investment  declines  below  its  cost  and  that  decline  is deemed other than
temporary,  the  amount  of  the  decline  below  cost  is  charged to earnings.
Harleysville  Group  monitors  its  investment  portfolio  and quarterly reviews
investments that have experienced a decline in fair value below cost to evaluate
whether  the  decline is other than temporary.  Such evaluations consider, among
other  things, the magnitude and reasons for a decline and the prospects for the
fair  value  to  recover  in  the  near  term.  Future adverse investment market
conditions, or poor operating results of underlying investments, could result in
an  impairment  charge  in  the  future.

     Harleysville  Group  evaluates  its  investment  portfolio  quarterly  to
determine  if  a  decline  in  fair  value  below  cost is other than temporary.
Harleysville Group has written down to fair value, without exception, any equity
security  that  has  declined  below  cost  by more than 20% and maintained such
decline  for  six months, or by 50% or more, in the quarter in which either such
decline  occurred.  In  some  cases,  securities  that have declined by a lesser
amount  or  for  a  shorter  period  of  time are written down if the evaluation
indicates  the decline is other-than-temporary. For example, one equity security
had  declined  for  a  short  period  of time but was written down in the fourth
quarter  of  2002 when the sale of the company at a value less than our cost was
announced.  Fair value of equity securities is based on the closing market value
as  reported  by  a  national stock exchange or Nasdaq.  The fair value of fixed
maturities  is  based  upon data supplied by an independent pricing service.  It
can  be  difficult  to  determine  the  fair  value of non-traded securities but
Harleysville  Group  does  not  own  a material amount of non-traded securities.

                      (Continued)

     Policy  Acquisition  Costs.  Policy acquisition costs, such as commissions,
premium  taxes and certain other underwriting and agency expenses that vary with
and  are  directly  related  to  the  production  of  business, are deferred and
amortized  over  the  effective  period of the related insurance policies and in
proportion  to  the  premiums earned.  The method followed in computing deferred
policy  acquisition  costs  limits  the  amount  of such deferred costs to their
estimated  realizable  value.  The estimation of net realizable value takes into
account  the  premium  to  be  earned,  related investment income over the claim
paying  period,  losses  and  loss  settlement expenses, and certain other costs
expected  to  be incurred as the premium is earned. Future changes in estimates,
the  most  significant of which is expected losses and loss settlement expenses,
may require adjustments to deferred policy acquisition costs.  If the estimation
of  net realizable value indicates that the acquisition costs are unrecoverable,
further  analyses are completed to determine if a reserve is required to provide
for  losses  that  may  exceed  the  related  unearned  premiums.

     Contingencies.  Besides  claims  related  to  its  insurance  products,
Harleysville  Group is subject to proceedings, lawsuits and claims in the normal
course  of  business.  Harleysville Group assesses the likelihood of any adverse
outcomes to these matters as well as potential ranges of probable losses.  There
can be no assurance that actual outcomes will not differ from those assessments.

     The  application  of  certain  of these critical accounting policies to the
periods  ended September 30, 2003 and 2002 is discussed in greater detail below.


Results  of  Operations

     Premiums  earned increased $12.7 million and $45.0 million during the three
and  nine  months  ended  September  30,  2003,  respectively. The increases are
primarily  due  to  increases  in  premiums earned for commercial lines of $17.7
million  and  $57.9  million  partially  offset by decreases of $5.0 million and
$12.9  million  in  personal lines premiums earned for the three and nine months
ended  September  30,  2003, respectively.  The increases in premiums earned for
commercial  lines  were  12.3%  and  14.2%  for  the three and nine months ended
September 30, 2003, respectively, primarily due to higher rates.  The decline in
premiums  earned  for

personal  lines  was 9.5% and 8.0% for the three and nine months ended September
30, 2003, respectively, primarily due to fewer policy counts partially offset by
higher  rates.  The reduction in personal lines volume was driven primarily by a
planned  reduction  of  business  in  certain  less  profitable  states  and the
implementation  of  other  more  stringent  underwriting  processes.

     Investment  income  decreased  $0.1  million  for  the  three  months ended
September  30,  2003  and  was  essentially  unchanged for the nine months ended
September 30, 2003 resulting from a lower yield on the fixed maturity investment
portfolio  partially  offset  by  an  increase  in  invested  assets.

     Realized  investment  gains (losses) worsened by $0.6 million for the three
months  ended  September  30,  2003  due to greater losses on the sale of equity
investments,  partially  offset  by  greater gains on the sale of fixed maturity
investments.  Realized  investment  losses  improved  $19.6 million for the nine
months  ended  September  30,  2003,  primarily  resulting  from  lesser  losses
recognized  on  investments  that  were  trading  below  cost  on  an
other-than-temporary  basis.

     There were no impairment charges in 2003 and $4.5 million and $28.2 million
of  impairment  charges  in  the three and nine months ended September 30, 2002,
respectively.  Harleysville  Group  had gross realized losses of $3.0 million in
the  nine  months  ended  September  30,  2003,  which  were  from  the sales of
securities  which  had  not  declined by more than 20% below their cost for more
than  six  months  at  the  time  of  their  sale.

     Harleysville Group holds securities with unrealized losses at September 30,
2003  as  follows:

     Substantially  all  of  the  fixed  maturity  securities  are classified as
available  for  sale  and  are  carried  at  fair  value  on  the balance sheet.

     There  are  20  positions  that  comprise  the  unrealized  loss  in equity
investments  at  September  30,  2003.  While eight of these positions have been
below  cost for more than six months, they have had volatile price movements and
have  not  been  significantly  below cost for significant continuous amounts of
time. Harleysville Group has been monitoring these securities and it is possible
that  some  may  be  written  down  in  the  future.

     There  are  $22.3  million in fixed maturity securities, at amortized cost,
that  at  September  30, 2003, had been below amortized cost for over 12 months.
These  are  comprised of airline enhanced equipment trust certificates (EETC) as
follows:

     After  the  events of September 11, 2001, air travel and the value of these
airlines'  EETC  securities  declined.  The  EETCs are all "A tranche" holdings,
which  means  they  are  in  a senior credit position to the underlying airplane
collateral  value  as  compared  to  B  and  C  tranche holders.  At the time of
issuance, the collateral was appraised at approximately twice the value of the A
tranche  EETCs.  Recent  estimates  indicate that in a distressed sale scenario,
the  value of the collateral would be approximately the same as the EETCs' cost.
During  the fourth quarter of 2002, United Airlines declared bankruptcy.  During
the  third  quarter  of  2003,  the  United  Airlines  EETCs  were downgraded to
non-investment  grade  by one rating agency but continued to carry an investment
grade rating by the other rating agency.  In the first quarter of 2003, the debt
ratings  of  American  Airlines  were  downgraded  to

non-investment grade.  In the second quarter of 2003, one of the rating agencies
upgraded  this  debt to investment grade. Harleysville Group is participating in
certain  EETC creditor committees and is monitoring developments. It is possible
that  these  EETCs  may  be  written down in the income statement in the future,
depending  upon  developments  involving both the issuers and world events which
impact  the  level  of  air  travel.

     Income  (loss)  before  income  taxes decreased $77.3 million for the three
months  ended  September  30,  2003 compared to the same prior year period.  The
decrease was primarily due to a greater underwriting loss.  Income (loss) before
income  taxes  decreased  $88.4  million for the nine months ended September 30,
2003 compared to the same prior year period. The decrease was primarily due to a
greater  underwriting  loss,  partially  offset  by  lesser  realized investment
losses.  The  greater  three and nine months underwriting loss was primarily due
to  higher  catastrophe  losses,  greater  loss  severity and an increase in the
provision  for  insured events in prior years.  The provision for insured events
in  prior  years  consists  of  $55.1  million  and  $76.8  million  of  adverse
development  for  the three and nine months ended September 30, 2003 compared to
$3.3 million and $(5.3) million of adverse (favorable) development for the three
and  nine  months  ended  September  30,  2002.

     An  insurance  company's  statutory combined ratio is a standard measure of
underwriting  profitability.  This ratio is the sum of (1) the ratio of incurred
losses  and  loss  settlement  expenses  to net earned premium; (2) the ratio of
expenses  incurred  for  commissions,  premium  taxes,  administrative and other
underwriting  expenses to net written premium; and (3) the ratio of dividends to
policyholders  to  net  earned  premium.  The  combined  ratio  does not reflect
investment  income,  federal  income  taxes  or  other  non-operating  income or
expense.  A  ratio  of  less  than  100 percent generally indicates underwriting
profitability.  Harleysville  Group's  statutory  combined  ratio  increased  to
137.2%  and  119.4%  for  the  three  and  nine months ended September 30, 2003,
respectively,  from  101.7%  and  101.9%  for  the  three  and nine months ended
September  30,  2002,  respectively.  Such  increase  was  due  to  a  higher
underwriting  loss  in  both  commercial  lines  and  personal  lines, primarily
resulting  from  the  adverse  loss  development  and  catastrophe  losses.

     The  statutory  combined  ratios by line of business for the three and nine
months  ended September 30, 2003, as compared to the three and nine months ended
September  30,  2002,  were  as  follows:

     The  commercial  lines  statutory  combined  ratio  increased to 140.1% and
119.0%  for  the  three and nine months ended September 30, 2003 from 100.0% and
99.9% for the three and nine months ended September 30, 2002.  The increases are
primarily  due to the adverse development in the provision for insured events in
prior  years, greater loss severity and greater catastrophe losses, particularly
in  commercial  multi-peril  insurance.

     The $55.1 million of third quarter adverse development in the provision for
insured  events in prior years was primarily in the following lines:  commercial
automobile  ($19.1  million),  workers  compensation ($17.1 million), commercial
multi-peril  ($13.5  million)  and  personal  automobile  ($4.5  million).  The
remaining  $21.7  million  of  adverse  development  in  the  nine  months ended
September  30,  2003  was  primarily  from $19.9 million of workers compensation
adverse  development  in  the  first quarter of 2003.  Of the nine month adverse
development,  $67.2  million was attributable to the 1998 to 2002 accident years
and  the  balance  was  attributable  to other accident years.  The 2003 adverse
development  represented  9.0% of the December 31, 2002 net liability for unpaid
losses  and  loss  settlement  expenses.

     The  adverse  development in workers compensation for the nine months ended
September  30,  2003  was  $37.0 million.  Harleysville Group had publicly noted
adverse  loss  trends  in its workers compensation line for several quarters and
the  trends  were again worse than expected in the third quarter of 2003.  These
trends  are  consistent  with  the  experience  of  other companies writing this
coverage,  many  of  which have, during the past twelve months, made substantial
additions  to  their  reserves for insured events in prior years in this line of
insurance.  The change in loss development patterns in  2003 was influenced by a
number of factors.  The reorganization of Harleysville Group's claims operations
resulted  in  more  proactive  claims  management  which, in turn, provided more
contemporaneous  loss  estimates.  In  addition,  weak  economic conditions have
hampered  the ability to return injured workers to employment thus extending the
estimated  length  of  disabilities and medical loss cost trends have increased.

     The  following  table presents workers compensation claim count information
for  the  total  pooled  business  in  which Harleysville Group participates and
payment amounts which are Harleysville Group's pooling share of the total pooled
amounts:

     Workers  compensation  losses  primarily  consist  of indemnity and medical
costs for injured workers.  The reduction in claim counts reflects the impact of
a  reduction  in  workers  compensation exposure as policy counts have declined.

     The adverse development in commercial and personal automobile primarily was
due to higher loss severity trends that became evident in the third quarter when
case  reserve  increases  were  recognized.  The  case  reserve  increases  for
commercial  automobile  primarily  related  to  adverse  legal  judgements.
Harleysville  Group  had  previously publicly noted an increase in litigation on
bodily injury cases and a slowing of the rate of settlement.  The combination of
all  of  these  factors  resulted  in the increased estimate of ultimate losses.

     The  adverse  development  in  commercial  multi-peril primarily was due to
higher  loss  severity trends that became evident in the third quarter when case
reserve increases were recognized.  Like commercial auto, the trend of increased
litigation  and  a slowing rate of settlement resulted in the increased estimate
of  ultimate losses.  While Harleysville Group had only incurred $1.5 million of
construction  defect  liability  losses over the past 10 years, it increased its
provision  for  insured  events  prior  years  by an additional $1.4 million for
estimated  losses  on  construction defect liability claims because of increased
case  activity  in  the  third  quarter  of  2003.

     Harleysville  Group  records  the  actuarial  best estimate of the ultimate
unpaid  losses  and  loss settlement expenses incurred and does not determine an
estimated  possible  range  of  loss.  Actuarial

                      (Continued)

loss  reserving techniques and assumptions, which rely on historical information
as adjusted to reflect current conditions, have been consistently applied during
the  periods  presented.  Changes  in  the  estimate of the liability for unpaid
losses  and  loss settlement expenses reflect actual payments and evaluations of
new information and data since the last reporting date.  These changes correlate
with  actuarial  trends.

     Because of the nature of insurance claims, there are uncertainties inherent
in  the  estimates of ultimate losses.  The aforementioned reorganization of the
claims  operation  has resulted in new people and processes involved in settling
claims.  As  a  result, more recent statistical data reflects different patterns
than  in  the past and give rise to uncertainty as to the pattern of future loss
settlements.  Litigation  on  bodily injury liability cases has increased during
the  past  two  years  while  the  rate of settlement has slowed.  These changed
patterns  give  rise  to  greater  uncertainty  as to the pattern of future loss
settlements  on  bodily  injury  liability  claims.  There  are  uncertainties
regarding future loss cost trends particularly related to medical treatments and
automobile  repair.  Court decisions, regulatory changes and economic conditions
can  affect  the ultimate cost of claims that occurred in the past. Accordingly,
the  ultimate  liability  for  unpaid  losses  and loss settlement expenses will
likely  differ  from  the  amount  recorded at September 30, 2003.  For every 1%
change  in  the  estimate,  the effect on pre-tax income would be $10.1 million.

     The  property  and  casualty  industry  has  had substantial aggregate loss
experience  from  claims  related  to  asbestos-related illnesses, environmental
remediation,  product  liability,  mold,  and  other  uncertain  exposures.
Harleysville  Group  has  not  incurred  significant  losses  from  such claims.

     The  personal lines statutory combined ratio increased to 127.3% and 120.7%
for  the  three  and nine months ended September 30, 2003 from 106.4% and 106.7%
for the three and nine months ended September 30, 2002.  The increases primarily
were  due  to  higher  catastrophe losses which affected the homeowners line and
higher  loss  severity  which  affected  each  of  the  personal  lines.

                      (Continued)

     Net catastrophe losses increased $10.0 million and $13.8 million and losses
ceded  under  the  aggregate  catastrophe  reinsurance  agreement  with  Mutual
decreased  $0.4 million and increased $4.4 million for the three and nine months
ended  September  30, 2003, respectively.  The increase in the nine month period
was  due  to  a  greater number and more severe catastrophes in the 2003 period,
including  $9.4  million  of  losses  from  Hurricane  Isabel.

     The  income  tax  expense for the three and nine months ended September 30,
2003  includes  the tax benefit of $2.6 million and $7.7 million associated with
tax-exempt  income  compared  to $2.4 million and $7.6 million in the same prior
year  periods.


Liquidity  and  Capital  Resources

     Operating  activities provided $113.3 million and $74.3 million of net cash
for the nine months ended September 30, 2003 and 2002, respectively.  The change
primarily  is  from  improved  underwriting cash flow, a change in the amount of
realized  losses  and  a  change  in  the amount of accounts payable and accrued
expenses.

     Investing  activities used $196.9 million and $66.7 million of net cash for
the  nine  months ended September 30, 2003 and 2002, respectively.  The increase
is  primarily  due to an increase in net purchases of fixed maturity investments
and  an  increase in net purchases of short-term investments due to the increase
in cash provided by operations and by the increase in cash provided by financing
activities.

     Financing activities provided $85.2 million of net cash for the nine months
ended September 30, 2003, compared to the use of $6.8 million of net cash in the
same  prior  year  period.  The change is primarily due to the issuance of debt,
partially  offset  by  an  increase  in  dividends  paid  and by the purchase of
treasury  stock  in  the  2003  period.

     Harleysville  Group  participates  in  a securities lending program whereby
certain  fixed  maturity  securities from the investment portfolio are loaned to
other institutions for a short period of time in return for a fee.  At September
30,  2003,  Harleysville Group held cash collateral of $230.3 million related to
securities  on  loan  with  a  market  value  of  $224.7  million.

     MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  RESULTS
          OF  OPERATIONS  AND  FINANCIAL  CONDITION
                      (Continued)

Harleysville  Group's  policy  is  to  require initial collateral of 102% of the
market value of loaned securities plus accrued interest, which is required to be
maintained  daily by the borrower at no less than 100% of such market value plus
accrued interest over the life of the loan.  Acceptable collateral includes cash
and  money  market  instruments,  government  securities,  A-rated  corporate
obligations,  AAA-rated  asset-backed securities or GIC's and Funding Agreements
from  issuers  rated  A  or  better.  The securities on loan to others have been
segregated  from  the  other invested assets on the balance sheet.  In addition,
the  assets  and liabilities have been grossed up to reflect the collateral held
under  the  securities  lending  program  and  the  obligation  to  return  this
collateral  upon  the  return  of  the  loaned  securities.

     Harleysville  Group  Inc.  maintained  $94.6 million of cash and marketable
securities  and  $11.6  million of dividends receivable from its subsidiaries at
September  30,  2003 which is available for general corporate purposes including
dividends, debt service, capital contributions to subsidiaries, acquisitions and
the  repurchase  of stock.  The Company's $75.0 million of notes payable are due
November  2003 and the Company will repay this indebtedness from the proceeds of
$100.0  million  of  notes payable due July 2013 which were issued in July 2003.
The Company has adopted a stock purchase plan under which the Company and Mutual
may  each  purchase up to 500,000 shares of Harleysville Group Inc. common stock
up  to a total of 1.0 million shares.  As of September 30, 2003, the Company had
repurchased  333,273 shares leaving 166,727 shares authorized to be repurchased.
The  Company  has  no  other material commitments for capital expenditures as of
September  30,  2003.


     RISK  FACTORS

     The  business, results of operations and financial condition, and therefore
the  value  of  the  Harleysville Group's securities, are subject to a number of
risks.  Some  of  those  risks  are  set forth in Exhibit 13(B) to the Company's
annual  report  on Form 10-K for fiscal year 2002, filed with the Securities and
Exchange  Commission  on  March  26,  2003.

ITEM  3.     QUANTITATIVE  AND  QUALITATIVE  DISCLOSURE
                       ABOUT MARKET RISK

     Harleysville  Group's  market risk generally represents the risk of gain or
loss that may result from the potential change in the fair value of Harleysville
Group's  investment portfolio as a result of fluctuations in prices and interest
rates.  Harleysville  Group  attempts  to  manage  its  interest  rate  risk  by
maintaining  an  appropriate  relationship  between  the average duration of the
investment  portfolio  and  the  approximate  duration  of  its  liabilities.

     Harleysville  Group  has  maintained approximately the same duration of its
investment  portfolio to its liabilities from December 31, 2002 to September 30,
2003.  In addition, the Company has not significantly changed its investment mix
or  market  risk  during  this  period.
