Dear  Agency  Principal:

     More  than  ten  years  ago, we introduced a discounted Stock Purchase Plan
enabling our best agencies to share in the ownership and success of Harleysville
Group  Inc. It came as no surprise that our agents welcomed this opportunity and
to  date  have  purchased more than $8.6 million of Harleysville Group stock (in
excess  of  476,000  shares). We have recently revised the Agency Stock Purchase
Plan to provide for an additional twenty subscription periods to allow agents to
continue  to  take  advantage  of  this  opportunity.

     As one of Harleysville's best agents, you are now eligible for Harleysville
Group's Amended and Restated Agency Stock Purchase Plan. This means that you can
purchase  shares  of  Harleysville  Group (HGIC on NASDAQ) common stock at a 10%
discount  from  the  market  price - without paying any brokerage commissions or
service  charges.  The  price  of  your  purchases  will be discounted below the
closing  price  of  our  stock  on  the  last day of each six-month subscription
period,  as  reported  on  the  NASDAQ  National  Market  System.

     With  an  enviably  solid balance sheet, escalating commercial lines profit
margins,  and  improving  personal  lines  fundamentals, our company's future is
bright  and Harleysville Group's stock represents an excellent value. Along with
our  current  dividend yield of 2.6%, Harleysville Group's stock appeals to many
long-term,  value-oriented  investors,  especially  when  coupled  with  the 10%
discount  offered  through  the Amended and Restated Agency Stock Purchase Plan.

     There  are  three  ways  in which you can participate. You may contribute a
fixed  percentage  of your direct bill commissions, make lump-sum contributions,
or  allocate  a  portion  of your annual agency profit sharing bonus, payable in
March (only available during the January 15th to July 14th subscription period).
Whichever method or methods you select, you may not contribute more than $12,500
in  any  subscription  period.  Mellon  Investor  Services will provide you with
semiannual  statements reflecting your stock purchases in order to simplify your
record-keeping  efforts.

     Enclosed  is  a  Subscription  Agreement.  If you decide to enroll, we must
receive  your completed Subscription Agreement by January 6th if you opt for the
direct  bill  commission  method.  Please  note  that  you  are also required to
complete,  sign  and  return  the  enclosed  W-9  along  with  your Subscription
Agreement.

     I'm  sure  you will agree that this plan provides you with an excellent way
to share in the future growth and prosperity of Harleysville Insurance. For full
information  on  the  program, please read the enclosed prospectus and brochure.

                REVISED  AND  RESTATED  AGENCY  STOCK  PURCHASE  PLAN

     The  following  is  a  description  in  question  and  answer  form  of the
provisions of the Plan offered to selected independent insurance agencies of the
Company's  parent,  or affiliated and subsidiary insurance companies. The Agency
Stock Purchase Plan was approved by the Company's Board of Directors on February
22,  1995,  amended  and  restated  on August 23, 1995. The Revised and Restated
Agency  Stock  Purchase Plan (the "Plan") was approved by the Company's Board of
Directors  on  June  7,  2005,  subject  to  shareholder  approval. The Plan was
approved  by  the  shareholders  by  written  consent  on  June  16,  2005.


Purpose  and  Advantages  of  the  Plan

     1.What  is  the  purpose  of  the  Plan?

     This  Plan  provides  an  Eligible Agency and its Key Employees, as defined
below, an opportunity to acquire a long-term proprietary interest in the Company
through  the purchase of the Company stock at a discount from fair market value.
In  offering  this Plan, the Company seeks to foster the common interests of the
Company  and  its  independent  agencies  and  employees  thereof  in  achieving
long-term  profitable  growth  for  the  Company.  Accordingly,  the Company has
created this Plan for the purpose of facilitating the purchase of, and long-term
holding  of, shares of its stock by an Eligible Agency and its Key Employees and
not  for such agency's or Key Employees' short-term gain. It is expected that an
Eligible  Agency  or  Key Employee that purchases shares of stock


Page 9 (I-5)


hereunder  will  hold  such shares on a long-term basis, as the Plan is not
intended  to  benefit  an  agency  or  employee  which demonstrates a pattern of
immediate  resale  of  shares acquired hereunder and, as discussed in Question &
Answer  6  below  regarding eligibility, such a pattern of conduct will cause an
otherwise  Eligible  Agency  to become ineligible for continued participation in
the Plan.

     2.What  are  the  advantages  of  the  Plan?

     Under  the Plan, an agency can utilize three convenient payment methods for
the  purchase  of  the  Company's  common  stock at a 10% discount from the fair
market  value  of  such  shares.  Purchases will also be made without paying any
brokerage  commissions  or  service  charges.


Administration

     3.Who  administers  the  Plan  for  participants?

     The  Plan shall be administered by a committee (the "Committee") consisting
of three employees of the Company who are appointed by and serve at the pleasure
of  the  Company's Board of Directors. The Committee may from time to time adopt
rules, regulations, and procedures for carrying out the Plan. Any interpretation
or construction of any provision of the Plan by the Committee shall be final and
conclusive  on  all  persons  absent  contrary action by the Board of Directors.

     4.Where  can  I  obtain  additional  information  about  the  Plan  and its
administrators?

     Additional  information  about  the  Plan  and  its  administrators  may be
obtained  by  contacting  the Company's Investment Department at (215) 256-5151.

     5.What  is  the  term  of  the  Plan?

     The  Plan  has been in effect since July 15, 1995 and will continue through
the  earlier  of  (i)  July 31, 2015 or (ii) the date on which plan participants
have subscribed for the total number of shares of the Plan. There will be twenty
(20)  Subscription  Periods  ("Subscription  Periods"). Each Subscription Period
will  run  from  July  15  through  January  14  or  January 15 through July 14.


Participation

      6.What  agencies  are  eligible  to  participate?

     Selected  independent  insurance  agencies that bring value to the Company,
its  parent, affiliates, and subsidiaries, directly or indirectly, as determined
by  the  Company  and  with  whom the Company seeks a long-term relationship are
eligible  (an "Eligible Agency") to participate in the Plan. The Company, in its
discretion,  may  base  eligibility on segmentation class or any other factor(s)
which  indicates  value  to the Company, its parent, affiliates or subsidiaries,
directly  or indirectly. An Eligible Agency shall be informed of its eligibility
to  enroll  in  the Plan. Continued eligibility will be subject to the Company's
periodic  review.


Page 10 (I-6)

     An  Eligible  Agency  that  participates in the Plan may direct that shares
purchased  under  the  Plan  from  its contribution account, as defined below in
Question  &  Answer  20, be registered as of the date of purchase in the name of
certain  persons  associated with the agency. Such persons shall only be (i) the
principal or principals of an Eligible Agency that is a proprietorship, (ii) the
general partner or general partners of an Eligible Agency that is a partnership,
(iii) the officers and stockholders of an Eligible Agency that is a corporation,
(iv)  employee benefit plans of such entities established for the benefit of any
of  the  foregoing persons, and (v) key employees designated by the principal or
principals  of  an Eligible Agency that is a proprietorship, the general partner
or  general  partners  of  an  Eligible  Agency  that  is  a partnership, or the
executive  officers  of  an Eligible Agency that is a corporation. The Company's
determination  of  which  persons are eligible for direct registration under the
Plan  will  be  final,  conclusive,  and  binding. All persons enumerated in (i)
through  (v) above who are designated by any such Eligible Agency to participate
in  the  Plan  are  referred  to  in  this  Prospectus  as  "Key  Employees."

     A  pattern  of  immediate  resale  of  stock acquired under this Plan by an
Eligible  Agency  or  a Key Employee thereof, shall be a factor in the Company's
determination  of  continued  eligibility  for the Plan because it shows that an
agency  and  its  Key  Employees  are not interested in sharing in the long term
profitable  growth of the Company. However, an otherwise Eligible Agency may not
participate  in  the  Plan  if  such  agency  is  subject  to  Section 16 of the
Securities  and  Exchange  Act of 1934 in connection with the Company or is a 5%
owner of the Company as defined in Section 13 of said Act. If an Eligible Agency
enrolled  in  the  Plan  becomes  subject to Section 16 or a 5% owner, then such
Eligible  Agency  will be deemed to have withdrawn from the Plan and all amounts
credited,  if  any,  will  be  refunded  in  cash.

     7.How  may  an  Eligible  Agency  participate  in  the  Plan?

     An  Eligible  Agency  can  enroll  in  the  Plan by completing and filing a
Subscription  Agreement  with  the Company. A Subscription Agreement is enclosed
with  this  Prospectus and additional Subscription Agreements may be obtained at
any  time  upon written request to the Company's local Marketing Representative.
In  addition, Subscription Agreements will be sent to each Eligible Agency prior
to  each  Enrollment  Period.

     8.What  does  a  Subscription  Agreement  provide?

     A Subscription Agreement allows each Eligible Agency to decide and identify
the  date  on  which  the  agency  desires  to  become enrolled in the Plan, the
amount(s) of contribution and the payment method(s) selected for purchases under
the  Plan.

     An  Eligible  Agency  must  indicate  on the Subscription Agreement how the
shares  purchased  are  to be allocated by specifying the names and addresses of
the  Eligible Agency and its Key Employees, where applicable, and the percentage
of  the total purchase each is to receive. If an Eligible Agency wants to change
its  allocation  for  any future Subscription Period, the Company must receive a
new  Subscription  Agreement on or before June 1 or December 1 of the applicable
Subscription  Period.

     9.When  may  an  Eligible  Agency  enroll  in  the  Plan?

     If an Eligible Agency chooses the direct bill commission payment method, as
explained  in Question & Answer 15, enrollment in the Plan may occur only during
Enrollment  Periods,  which


Page 11 (I-7)

are  from  the  1st  through  the 14th day of July and January of each year
commencing  in  July,  2005. Once enrolled in the direct bill commission payment
method,  an  Eligible  Agency's  participation  in  the Plan continues until the
agency  terminates enrollment in the Plan or the agency ceases to be an Eligible
Agency.  If an Eligible Agency chooses the lump sum payment method, as explained
in  Question  &  Answer  17,  an  Eligible  Agency  may  enroll  by submitting a
Subscription  Agreement to the Company and making a lump sum payment by June 1st
or  December  1st.  If  an  Eligible Agency chooses the bonus payment method, as
explained  in  Question  &  Answer  18,  enrollment  in  the  Plan  may occur by
submitting  a  Subscription  Agreement  during the Enrollment Period immediately
preceding the January 15-July 14 Subscription Period.

     10.May  an  Eligible  Agency  transfer  its  subscription rights to another
person  or  agency?

     No.  No  Eligible Agency may assign its subscription or rights to subscribe
to  any  other person or agency and any such attempted assignment shall be void.
However,  an Eligible Agency may permit direct registration of stock in the name
of  a  Key  Employee  as  described  in  Question  &  Answer  6.


Costs  and  Expenses

     11.Are  there  any  expenses  to  participants in connection with purchases
under  the  Plan?

     No.  Eligible  Agencies  will  not  be  obligated  to  pay  any  brokerage
commissions  or other charges with respect to the purchase of Common Stock under
the  Plan.  However,  a participating Eligible Agency which requests that Mellon
sell  shares  of Common Stock held in the participant's account in the Plan will
pay  any  applicable  brokerage  fees  incurred  in  connection  with such sale.


Purchases

     12.What  is the source and number of shares available to be purchased under
the  Plan?

     Shares  purchased  under  the Plan may be authorized but unissued shares of
Common  Stock  of  the  Company or treasury stock reacquired by the Company. The
total number of shares available for purchase under the Plan is 1,000,000. As of
November  30,  2005,  499,394  shares have been issued and 500,606 shares remain
available  for  purchase.

     13.What  is  the  price of shares of Common Stock purchased under the Plan?

     The  Subscription  Price for each share of Common Stock purchased under the
Plan will be 90% of the fair market value of such shares on the last trading day
of  the  Subscription  Period;  provided, however, the price shall never be less
than  the  par  value  of one dollar ($1.00) per share. "Fair market value" of a
share will be the Closing Price as reported on the NASDAQ National Market System
on  the  last  day  of  the  Subscription  Period  on  which  a  trade  occurs.


     14.How  may  an  Eligible  Agency  pay for shares purchased under the Plan?

Page 12 (I-8)

     The  Subscription  Price  for shares purchased under the Plan is payable by
participants  by  means  of  three  payment  methods,  direct  bill  commission
deduction,  lump  sum  payment  or  bonus  deduction.

     15.What  is  the  direct  bill  commission  payment  method?

     Under  the  direct  bill  commission payment method, an Eligible Agency may
contribute to the Plan a minimum of one per cent (1%) and up to a maximum of ten
per  cent  (10%)  of the participant's direct bill commission payments, in whole
number increments, but in no event greater than $12,500 per Subscription Period.
"Direct  bill  commission payments" means those commissions which are earned and
actually  available  for payment for a semi-monthly period to an Eligible Agency
for personal and commercial direct bill policies after all offsetting debits and
credits  are  applied  as  determined  solely  from  the  Company's  records.

     16.May an Eligible Agency that chooses the direct bill change the method or
amount  of  contribution  made  or  withheld  under  the  Plan?

     Yes.  An Eligible Agency choosing the direct bill commission payment method
may change the method and/or amount of contribution by filing a new Subscription
Agreement  with the Company during the applicable Enrollment Period. Such change
will  become  effective  during  the  following  Subscription  Period.

     17.What  is  the  lump  sum  payment  method?

     Under  the  lump  sum  payment method, an Eligible Agency may, by June 1 or
December  1  of  the applicable Subscription Period, elect to make lump sum cash
payments for the purchase of Common Stock under the Plan. Lump sum cash payments
shall  not be less than $1,000 and, if the Eligible Agency is not enrolled under
the  direct  bill  commission  payment  method,  not  more than $6,000 or, if an
Eligible  Agency  is  enrolled in the direct bill commission payment method, not
more  than  $12,500.  If  the  Eligible Agency that chooses the lump sum payment
method  does not submit a check with the Subscription Agreement, the Agency must
complete a separate Lump Sum Contribution form and send it to the Company at the
time  it  submits  the  check.

     18.What  is  the  bonus  payment  method?

     During  the  Enrollment Period immediately preceding the January 15 through
July  14  Subscription Period, an Eligible Agency may designate a percentage, in
whole  number  increments,  subject  to  a  maximum  dollar amount not to exceed
$12,500,  of  the bonus payable to the participant under the terms of the Agency
Incentive  Plan  (or  its  equivalent) to be withheld for the purchase of Common
Stock  under  the  Plan.

     19.Are  there limitations on the amount of contributions or purchases which
can  be  made?

     Yes.  During any one Subscription Period, the total allowable contributions
for  purchases  from all payment methods (described in Question & Answer 15, 17,
and 18 above) for each Eligible Agency shall not exceed $12,500. At the close of
each  Subscription  Period, each agency's contributions from all payment methods
will  be  totaled  and  any excess contributions above $12,500 shall be returned
without interest to the Eligible Agency within a reasonable time. If at any time



Page 13 (I-9)

throughout a Subscription Period, an Eligible Agency's total payments exceed the
maximum  amount permitted for the agency and the agency so requests, the Company
will return the excess amount without interest to the agency within a reasonable
period.

     20.How  are  purchases  made  under  the  Plan?

     The  Company  shall  maintain  on its books a contribution account for each
participating  Eligible  Agency.  All  contributions  made by an Eligible Agency
during  a  Subscription  Period will be credited to the contribution account for
that  Eligible  Agency.  At  the  end  of  each  Subscription Period, the amount
credited  to  each Eligible Agency's contribution account will be divided by the
Subscription  Price  for  such  Subscription  Period  and  the Eligible Agency's
contribution  account  will  be credited with the number of whole and fractional
shares  (computed  to  no less than four decimal places) which results. The full
amount  of  shares,  including  fractional shares, will then be allocated to the
accounts  maintained  on  the books of the Company's stock transfer agent ("Plan
Accounts")  for the Eligible Agency and its Key Employees in accordance with the
allocation  specified  in  the section on stock registration of the most current
Subscription  Agreement  filed  with  the  Company  by  the Eligible Agency. The
Company  will  rely  on  the most current Subscription Agreement and will not be
liable  as  long  as  the  shares  are  allocated  in  accordance with the stock
registration  section.  If  the  number  of  shares  subscribed  for  during any
Subscription  Period  exceeds  the number of shares available for sale under the
Plan,  available  shares will be allocated to participating Eligible Agencies in
proportion to their Plan Accounts and any excess contributions shall be returned
to  the  participating  Eligible  Agency  without  interest.

     Reports  to  Participants

     21.What  kind  of  reports will be sent an Eligible Agency participating in
the  Plan?

     Each  Eligible Agency participating in the Plan and, if applicable, its Key
Employees  will  receive  as promptly as practicable after each purchase for the
participating  Eligible  Agency's account, a statement of account describing the
amount  contributed,  the  number  of  shares purchased, the price per share and
total  Harleysville  Group  Inc.  shares  accumulated  under  the  Plan.  These
statements  will  provide a continuing record of the dates and cost of purchases
and  should  be  retained for income tax purposes. In addition, each stockholder
will  also  receive  the Company's annual and quarterly reports to stockholders,
notices  of  stockholder  meetings  and  proxy  statements  and Internal Revenue
Service  ("IRS")  information  for  reporting  dividends  paid.

     Certificates  for  Shares;  Sale  of  Shares

     22.Are  stock  certificates  issued  for  shares of Common Stock purchased?

     Unless  an  agency  requests, certificates for Common Stock purchased under
the  Plan  will not be issued. The number of shares credited to an account under
the  Plan  will  be shown on the agency's and, if applicable, its Key Employees'
statement  of account. However, except as indicated below, an agency and its Key
Employees may receive certificates for full shares accumulated in their accounts
under  the  plan  at  any  time  by  sending  a written request to the Company's
transfer  agent,  currently  Mellon.


Page 14 (I-10)

     An  agency's rights under the Plan and shares credited to the account of an
agency  or its Key Employees under the Plan may not be pledged. An agency or Key
Employee  that  wishes  to  pledge its shares must request that certificates for
such  shares  be  issued in the agency's or Key Employee's name, as the case may
be.

     Certificates  for  fractional  shares  will  not  be  issued  under  any
circumstances.

     23.In  whose  name are accounts maintained and certificates registered when
issued?

     Plan  Accounts  will  be  maintained  in  the name of the agency or the Key
Employee,  as  the  case may be. Consequently, certificates when issued for full
shares  will  be  registered  in  the  same  name.

     Upon  written request to Mellon, certificates will be registered and issued
in  names other than the account name, subject to compliance with any applicable
laws  and  the  payment by the agency of any applicable taxes, provided that the
request meets the usual requirements of Mellon for the recognition of a transfer
of  Common  Stock  of  the  Company.

     24.When and how may an agency that has purchased stock under this Plan or a
Key  Employee that has stock registered in a Key Employee's name withdraw shares
purchased  under  the  Plan?

     An  agency  that has purchased shares under the Plan or a Key Employee that
has  stock  registered in a Key Employee's name may withdraw all or a portion of
the shares of a Common Stock credited to its account by giving written notice to
Mellon  to  that  effect and specifying in the notice the number of shares to be
withdrawn.  When  an  agency  or Key Employee withdraws shares from its account,
certificates  for  whole  shares  of  Common  Stock so withdrawn will be issued.
However,  if  the  agency or Key Employee so requests, Mellon will sell all or a
portion  of the shares of Common Stock in the agency's or Key Employee's account
and  deliver  the proceeds, less any applicable brokerage fees, to the agency or
Key  Employee,  as  the  case  may  be.

     25.What  happens  to  any  fractional  interest  withdrawn  from  the Plan?

     Any  fractional  interest  withdrawn  will  be  sold  by  Mellon as soon as
practicable,  and  shall be sold at the market price prevailing when the sale is
made,  and  a  check  remitted  promptly  for  the  proceeds  thereof,  less any
applicable  brokerage  fees.  In  no  case  will  certificates  representing  a
fractional  interest  be  issued.

     Withdrawal  from  Plan

     26.How  and  when  may  an  Eligible  Agency  withdraw  from  the  Plan?

     An Eligible Agency may withdraw from the Plan at any time by giving written
notice  to  the  Company  of the agency's desire to do so. Termination of agency
status  for  any reason will be treated as an automatic withdrawal. If an agency
withdraws  from the Plan, such agency, if it continues to be an Eligible Agency,
may  not  re-enroll  until  after the next full Subscription Period has elapsed.


Page 15 (I-11)

     27.What  happens  to  any  amounts  credited  to  an  Eligible  Agency's
contribution  account  at  the  time  of  withdrawal?

     All  amounts  credited  to an Eligible Agency's contribution account at the
time of withdrawal will be refunded to the participant in cash without interest.

     Other  Information

     28.What  happens if the Company declares a stock split or stock dividend or
changes or exchanges its Common Stock for shares of stock or other securities of
its  own  or  another  corporation?

     If shares of the Company's Common Stock are changed into or exchanged for a
different  number  or kind of shares of stock or other securities of the Company
or  another  corporation,  as in a merger, consolidation or otherwise, or if the
Company  declares a stock split or stock dividend, there will be substituted for
or  added  to each share reserved for sale under the Plan the number and kind of
shares of stock or other securities into or for which the Company's Common Stock
will  be  so changed or exchanged, or to which each such share will be entitled.

     29.When  do agencies participating in the Plan and its Key Employees become
entitled  to  the  rights  of  a  shareholder  of  the  Company?

     An  agency  participating  in  the  Plan  or  Key Employees who have shares
registered  in their name will become entitled to vote, to receive dividends and
to  all  other  rights  as  a  shareholder of the Company with respect to shares
issued  under  the  Plan  on the first day following the end of the Subscription
Period during which such shares were purchased. If an agency or Key Employee has
shares  credited  to an account under the Plan on a record date for a meeting of
stockholders,  the  agency  or Key Employee will be able to vote those shares in
the  same  manner  as  shares  for  which  the  agency  or  Key  Employee  holds
certificates.  The  agency  or  Key  Employee  will  be sent proxy material with
respect to that meeting. An agency or Key Employee will be entitled to vote both
the  shares  of  Common Stock held in the agency's or Key Employee's account, as
the  case  may be, and those for which certificates are issued. An agency or Key
Employee  may  vote  in  person  or  by  proxy  at  any  such  meeting.

     30.What  are  the  federal  income tax consequences of participation in the
Plan?

     At  the  time  of  purchase,  an  agency will be treated as having received
ordinary  income  in  an amount equal to the difference between the Subscription
Price  paid  and the then fair market value of the Common Stock acquired. At the
end  of  each  calendar year, the Company will mail to each agency, which is not
incorporated  and  has earned income of at least $600.00, a Form 1099 reflecting
the  amount of ordinary income earned under the Plan. The Company is entitled to
a  deduction  at  the same time in a corresponding amount. The agency's basis in
the  Common  Stock  acquired  is  equal to the purchase price plus the amount of
ordinary  income  recognized.  When an agency disposes of shares of Common Stock
acquired  under  the  Plan,  any  amount  received in excess of the value of the
shares  of Common Stock on which the agency was previously taxed will be treated
as long-term or short-term capital gain depending upon the holding period of the
shares.


Page 16 (I-12)


If the amount received is less than that value, the loss will be treated
as  long-term  or  short-term capital loss, depending upon the holding period of
the  shares  (which  begins  on  the  date  after  the  share  is  acquired).
If  an  Eligible Agency that purchases shares has such shares registered in
the  name  of  Key  Employees,  such shares may be income to such Key Employees,
depending upon the status of the Key Employee and the facts and circumstances of
the  registration  in  the  name  of  the  Key  Employees.

     Each  participating agency or Key Employee is advised to consult with a tax
advisor  to  determine  the  tax consequences of a particular transaction in the
agency's  account  or  the  tax  treatment  of registration in the name of a Key
Employee.

     31.What  are the responsibilities of the Company and Mellon under the Plan?

     Mellon,  as agent, maintains account records for participating agencies and
Key  Employees  and  notifies  them of transactions in, and the status of, their
accounts.  Mellon  shall have no duties, obligations or liabilities with respect
to  the  Plan  except  such  as  are  expressly  set  forth  in this Prospectus.

     The  Company  and Mellon, in administering the Plan, will not be liable for
any  act  done in good faith or for their good faith omission or act, including,
without limitation, with respect to the prices at which shares are purchased for
the  participant's  account  and the times when such purchases are made, or with
respect to any loss or fluctuation in the market value of the Common Stock after
the  purchase  of  shares.

     All  notices  from Mellon to a participating agency or Key Employee will be
mailed to the agency's or Key Employee's address of record, and the mailing of a
notice  to  an  agency's  or  Key  Employee's most recent address of record will
satisfy  Mellon's obligation to provide notice to that participant. Accordingly,
an  agency  and  Key  Employees  should promptly advise the Company and Chemical
Mellon  of  any  change  of  address.

     32.May  the  Plan  be  changed  or  discontinued?

     Yes.  The  Company's  Board of Directors has the right to amend, modify, or
terminate  the  Plan  at  any  time  without  notice so long as no participating
agency's  existing  rights  are  adversely  affected as a result of such change,
amendment  or  modification.  The  Company  must  seek  stockholder approval for
certain  amendments  to  the  Plan  as  required  by  Nasdaq.

                                  RISK  FACTORS

     You  should  consider  carefully  the following risks, as well as the other
information  contained  in  this  Prospectus.  If  any  of  the following events
described  in  the  risk  factors  below actually occur, our business, financial
condition  and  results  of  operations  could  be  adversely  affected.

Risks  Related  to  the  Property  and  Casualty  Insurance  Industry  Generally


Page 17 (I-13)


If  our  estimated  liability  for  losses  and loss settlement expenses is
incorrect,  our reserves may not be adequate to cover our ultimate liability for
losses  and  loss  settlement  expenses  and  may  have  to  be  increased.

     We  are  required to maintain loss reserves for our estimated liability for
losses  and  loss  settlement  expenses  associated with reported and unreported
claims  for each accounting period. We regularly review our reserving techniques
and  our overall amount of reserves and, based on our estimated liability, raise
or  lower the levels of our reserves accordingly. If our estimates are incorrect
and  our  reserves are inadequate, we are obligated to increase our reserves. An
increase in reserves results in an increase in losses and a reduction in our net
income  for  the  period  in  which  the  deficiency  in reserves is identified.
Accordingly, an increase in reserves could have a material adverse effect on our
results of operations, liquidity and financial condition. For every 1% change in
our  reserve, our pre-tax income is affected by approximately $12.2 million. Our
reserve amounts are estimated based on what we expect our ultimate liability for
losses  and  loss  settlement expenses to be. These estimates are based on facts
and circumstances of which we are aware, predictions of future events, trends in
claims  severity  and  frequency and other subjective factors. Although we use a
number of methods to project our ultimate liability, there is no method that can
always  exactly  predict  our  ultimate liability for losses and loss settlement
expenses.

     In addition to reviewing our reserving techniques, as part of our reserving
process  we  also  consider:

     *information  regarding  each  claim  for  losses;
     *our  loss  history  and  the  industry's  loss  history;
     *legislative  enactments,  judicial  decisions  and  legal  developments
      regarding  damages;
     *changes  in  political  attitudes;  and
     *trends  in  general  economic  conditions,  including  inflation.

If  certain  catastrophic  events  occur,  they  could  have  a  significant
impact  on  our  financial  and  operational  condition.

     Results  of  property  insurers  are  subject  to  weather and other events
prevailing  in  any  given  year. While one year may be relatively free of major
weather  or  other disasters, another year may have numerous such events causing
results  for  that  year  to  be  materially  worse  than  for  other  years.

     Our insurance subsidiaries have experienced, and are expected in the future
to experience, catastrophe losses. It is possible that a catastrophic event or a
series  of  multiple catastrophic events could have a material adverse effect on
the  operating  results  and  financial condition of our insurance subsidiaries,
thereby  limiting  the ability of our insurance subsidiaries to pay dividends to
us.  In  the  last  6  years,  the  largest catastrophe to affect our results of
operations  was  Hurricane Floyd in the third quarter of 1999, which resulted in
$15.1  million  of  losses.

     Various  events  can  cause  catastrophes, including severe winter weather,
hurricanes, windstorms, earthquakes, hail, war, terrorism, explosions and fires.
The  frequency  and severity


Page 18 (I-14)

of  these  catastrophes  are inherently unpredictable. The extent of losses
from  a  catastrophe is a function of both the total amount of insured exposures
in  the  area affected by the event and the severity of the event. Our insurance
subsidiaries  seek to reduce the impact on our business of a catastrophe through
geographic  diversification  and  through  the  purchase of reinsurance covering
various  categories  of  catastrophes,  which  generally  excludes  terrorism.
Nevertheless, reinsurance may prove inadequate if:

     *  a  major  catastrophic  loss  exceeds  the  reinsurance  limit,  or
     *  an  insurance  subsidiary  pays  a  number  of  smaller  catastrophic
loss  claims  that,  individually,  fall below the subsidiary's retention level.

     We  are  heavily  regulated  in  the  states  in which we operate and if we
violate  those  regulations  or  if  the  regulations  unreasonably restrict our
ability  to do business, it could have an adverse effect on our business. We are
subject  to  extensive  supervision  and  regulation  in  the states in which we
transact  business.  The  purpose  of  supervision  and regulation is to protect
individual  policyholders  and not shareholders or other investors. Our business
can  be adversely affected by private passenger automobile insurance regulations
and  any  other regulations affecting property and casualty insurance companies.
For  example,  laws and regulations can reduce or set rates at levels that we do
not believe are adequate for the risks we insure. Other laws and regulations can
limit  our ability to cancel or refuse to renew policies and require us to offer
coverage  to  all  consumers.  Changes  in  laws  and  regulations,  or  their
interpretations,  pertaining  to  insurance, including workers compensation, may
also  have  an  adverse  effect on our business. Although the federal government
does  not directly regulate the insurance industry, federal initiatives, such as
federal  terrorism  backstop legislation, from time to time, also can impact the
insurance  industry.

     In  addition,  proposals  intended  to control the cost and availability of
health  care  services  have  been  debated  in  the  U.S.  Congress  and  state
legislatures.  Although we do not write health insurance, rules affecting health
care  services  can  affect  other  insurance  that  we write, including workers
compensation  and commercial and personal automobile and liability insurance. We
cannot  determine  whether or in what form health care reform legislation may be
adopted  by the U.S. Congress or any state legislature. We also cannot determine
the  nature  and effect, if any, that the adoption of health care legislation or
regulations,  or  changing  interpretations, at the federal or state level would
have  on  us.

If  demand  for  property  and  casualty  insurance decreases, it could have  an
adverse  impact  on  our  business.

     Historically,  the  results of the property and casualty insurance industry
have  been  subject to significant fluctuations over time due to competition and
due  to  unpredictable  developments,  including:

     *  natural  and  man-made  disasters;
     *  fluctuations  in  interest rates and other  changes  in  the  investment
        environment  that  affect  returns  on  our  investments;
     *  inflationary  pressures  that  affect  the  size  of  losses;  and
     *  legislative  and  regulatory  changes  and  judicial  decisions  that
        affect  insurers'liabilities.


Page 19 (I-15)

     The  demand  for  property  and casualty insurance, particularly commercial
lines, also can vary with the overall level of economic activity. In addition to
the  cyclicality  of  the property and casualty industry, our surety business is
affected adversely by economic downturns that make it difficult for the insureds
whose  obligations  we  guarantee  to  fulfill  their  obligations.

     If  we  are  unable  to  reduce  our  exposure  to  risks  through reliable
reinsurance  or  if  the cost of reinsurance increases, our risk of loss, or the
cost  of  controlling  our  risk  of  loss,  will  increase.

     We  transfer a portion of our exposure to selected risks to other insurance
and  reinsurance  companies  through  reinsurance  arrangements.  Under  our
reinsurance  arrangements,  another  insurer  assumes a specified portion of our
losses  and  loss  adjustment  expenses  in  exchange for a specified portion of
policy  premiums.  The  availability,  amount  and cost of reinsurance depend on
market  conditions and may vary significantly. Any decrease in the amount of our
reinsurance  will  increase our risk of loss. Furthermore, we face a credit risk
when we obtain reinsurance because we are still liable for the transferred risks
if  the  reinsurer  cannot  meet  the  transferred  obligations.  Therefore, the
inability  of  any  of  our  reinsurers  to meet its financial obligations could
materially  and  adversely  affect  our  operations.

     Many  reinsurers  experienced  significant  losses related to the terrorist
acts  of September 11, 2001, and future terrorist acts may have similar effects.
As  a  result,  we  may  incur  significantly  higher reinsurance costs and more
restrictive  terms  and  conditions,  or may be unable to obtain reinsurance for
some  types  of  commercial  exposures.

     The  threat  of  terrorism  and  military  and  other actions may result in
decreases  in  our  net  income,  revenue  and  assets  under management and may
adversely  affect our investment portfolio. The threat of terrorism, both within
the  United  States  and  abroad,  and military and other actions and heightened
security  measures  in response to these types of threats, may cause significant
volatility  and  declines in the equity markets in the United States, Europe and
elsewhere,  as  well as loss of life, property damage, additional disruptions to
commerce  and  reduced  economic  activity. Actual terrorist attacks could cause
losses  from  insurance  claims  related  to the property and casualty insurance
operations  of  Harleysville  Group,  as well as a decrease in our stockholders'
equity,  net  income  and/or  revenue.  The  effects  of  changes  related  to
Harleysville  Group  may  result in a decrease in our stock price. The Terrorism
Risk  Insurance  Act  of  2002 requires that some coverage for terrorist loss be
offered  by  primary  property  insurers  and  provides  Federal  assistance for
recovery  of  claims  through  2005.  In  addition,  some  of  the assets in our
investment portfolio may be adversely affected by declines in the equity markets
and  economic  activity  caused  by  the  continued threat of terrorism, ongoing
military  and  other  actions  and  heightened  security  measures.

     We  cannot  predict  at  this time whether and the extent to which industry
sectors  in  which  we  maintain  investments  may  suffer losses as a result of
potential  decreased  commercial and economic activity, or how any such decrease
might  impact  the  ability of companies within the affected industry sectors to
pay  interest  or  principal  on  their  securities,  or  how  the  value of any
underlying  collateral  might  be  affected.

     We can offer no assurances that the threats of future terrorist-like events
in  the  United  States and abroad or military actions by the United States will
not  have  a  material  adverse  effect  on our business, financial condition or
results  of  operations.


Page 20 (I-16)

Certain  changes  in  the  accounting  standards  issued  by  the  Financial
Accounting  Standards  Board  or  other  standard-setting  bodies  could  have a
material  adverse  impact  on  our  reported  net  income.

     We  are  subject  to the application of GAAP, which is periodically revised
and/or  expanded.  As such, we are periodically required to adopt new or revised
accounting  standards  issued  by recognized authoritative bodies, including the
Financial  Accounting  Standards  Board.  It  is  possible  that  future changes
required  to  be  adopted  could change the current accounting treatment that we
apply  and  such changes could result in material adverse impacts on our results
of  operations  and  financial  condition.

If  our  investments  lose  value,  our  revenues and earnings will be adversely
affected.

     Like  many  other  property  and casualty insurance companies, we depend on
income  from  our investment portfolio for a significant portion of our revenues
and  earnings.  Any  significant decline in our investment income as a result of
falling  interest  rates,  decreased  dividend  payment  rates or general market
conditions  would have an adverse effect on our results. Any significant decline
in the market value of our investments would reduce our shareholders' equity and
our  policyholders'  surplus, which could impact our ability to write additional
business.

If  our  financial  strength  ratings are reduced, we may be adversely impacted.

     Insurance  companies  are subject to financial strength ratings produced by
external  rating  agencies.  Higher ratings generally indicate greater financial
stability  and  a stronger ability to pay claims. Ratings are assigned by rating
agencies  to  insurers  based  upon  factors  that  they believe are relevant to
policyholders.  Ratings  are  not  recommendations  to  buy,  hold  or  sell our
securities.

     Although  other  agencies  cover  the  property  and  casualty industry, we
believe  our  ability to write business is most influenced by our rating from A.
M.  Best.  According  to  A.  M.  Best,  its  ratings  are designed to assess an
insurer's  financial  strength  and  ability  to  meet  ongoing  obligations  to
policyholders.  Currently,  our rating from A. M. Best is "A-", the 4th of A. M.
Best's  15  ratings.  A  rating  below  "A-"  from  A.  M. Best could materially
adversely  affect  the business we write. We believe that our financial strength
rating  from  Moody's  (which  is  A3,  the 7th of Moody's 21 ratings), although
important,  has  less of an impact on our business. An unfavorable change in our
Moody's  financial strength rating, however, could make it more expensive for us
to  access  capital markets. We cannot be sure that we will maintain our current
A.  M.  Best  or  Moody's  ratings.  Although  Standard  & Poor's rates our debt
securities at BBB-/Negative (the 10th of Standard & Poor's 23 ratings), Standard
&  Poor's  does  not  currently  rate our financial strength and ability to meet
ongoing  obligations.

Risks  Related  to  Our  Company  in  Particular

We  face  significant  competition  from  other  regional and national insurance
companies,  agents  and from self-insurance, which may result in lower revenues.

     We compete with local, regional and national insurance companies, including
direct  writers of insurance coverage. Many of these competitors are larger than
we  are  and  many have greater financial, technical and operating resources. In
addition,  we  face  competition  within  each  insurance  agency that sells our
insurance  because we sell through independent agencies that represent more than
one  insurance  company.


Page 21 (I-17)


     The  property  and casualty insurance industry is highly competitive on the
basis of product, price and service. If our competitors offer products with more
coverage,  or  price  their  products  more aggressively, our ability to grow or
renew  our  business  may  be adversely impacted. There are more than 250 groups
writing  property  and  casualty  insurance  in  the  United  States, and we are
approximately  60th in size. Our most significant competitors vary significantly
in  our  different  lines  of business and in the geographic markets in which we
compete.  The  internet  also  could  emerge  as  a  significant  source  of new
competition, both from existing competitors using their brand name and resources
to  write  business  through this distribution channel and from new competitors.

     We also face competition because of entities that self-insure, primarily in
the commercial insurance market. From time to time, certain of our customers and
potential  customers  may  examine  the benefits and risks of self-insurance and
other  alternatives  to  traditional  insurance.

     A number of new, proposed or potential legislative or industry developments
could  further  increase  competition  in  the  property  and casualty insurance
industry.  These  developments  include:

     *  the  enactment of the Gramm-Leach-Bliley Act of 1999, which could result
        in  increased  competition  from  new  entrants to the insurance market,
        including  banks  and  other  financial  service  companies;
     *  programs  in  which  state-sponsored  entities  provide  property
        insurance  in  catastrophe-prone  areas  or  other  alternative  market
        types  of  coverage;  and
     *  changing  practices  caused by the internet,  which  have led to greater
        competition  in  the  insurance  business  and,in  some  cases,  greater
        expectations  for  customer  service.

     New  competition  from  these developments could cause the supply or demand
for  insurance to change, which could adversely affect our results of operations
and  financial  condition.

If  adverse  conditions  in  the eastern and midwestern United States exist, our
business  would  be  disproportionately  impacted.

     We  write  property  and  casualty  insurance  business  in the eastern and
midwestern United States. Consequently, unusually severe storms or other natural
or  man-made  disasters  that  destroy  property in these states could adversely
affect  our  operations.  Our  revenues  and  profitability  also are subject to
prevailing  economic  and  regulatory conditions in the states in which we write
insurance.  We  may be exposed to risks of adverse developments that are greater
than  if  we  conducted  business  nationwide.

We  depend  on  independent  insurance  agents,  which  exposes  us to risks not
applicable  to  companies  with  dedicated  agents.

     We  market  and  sell  our  insurance  products  through  independent,
non-exclusive  insurance  agencies. These agencies are not obligated to sell our
insurance  products,  and  generally  they  also sell our competitors' insurance
products.  As  a result, our business depends in part on the marketing and sales
efforts  of  these  agencies.  If  we  diversify  and  expand  our  business
geographically,  then  we  may  need  to  expand  our  network  of  agencies  to
successfully  market our products. If these agencies fail to market our products
successfully,  our  business may be adversely impacted. Also, independent agents
may  decide to sell their businesses to banks, other insurance agencies or other
businesses. Changes in ownership of agencies, or expansion of


Page 22 (I-18)

agencies through acquisition, could adversely affect an agency's ability to
control growth and profitability, thereby adversely affecting our business.

If our insurance subsidiaries are not able to pay adequate dividends to us,
our ability to meet our obligations and pay dividends would be affected.

     Our  principal  assets  are  the  shares  of capital stock of our insurance
company  subsidiaries.  We  rely  on  dividends  from  our  insurance  company
subsidiaries  to  meet  our  obligations  for  paying  principal and interest on
outstanding  debt obligations and for paying corporate expenses and dividends to
shareholders.  As  described  below,  the  payment of dividends by our insurance
company  subsidiaries  is  subject to regulatory restrictions and will depend on
the  surplus  and  future  earnings  of  these  subsidiaries,  as  well as other
regulatory  restrictions.  As  a result, we may not be able to receive dividends
from  these  subsidiaries  at  times  and  in  amounts  necessary  to  meet  our
obligations  or  to  allow  us  to  pay  dividends.

     Generally, the maximum dividend that may be paid by an insurance subsidiary
during  any  year  without  prior  regulatory  approval  is  limited to a stated
percentage  of  that  subsidiary's  statutory  surplus  as of a certain date, or
adjusted  net  income  of  the  subsidiary for the preceding year. Our insurance
subsidiaries  paid  $26.6  million of dividends to us in 2004, none in 2003, and
$12.0  million  in  2002.  Of  the  dividends  paid  in 2004, $11.6 million were
declared  by our insurance subsidiaries in 2002. Applying the current regulatory
restrictions  as  of  December  31,  2004,  $51.0 million would be available for
distribution  to  us  without  prior  approval  during  2005.  We  anticipate no
objections  to the payment of the dividends described in the preceding sentence.

     Notwithstanding  the foregoing, if insurance regulators otherwise determine
that  payment of a dividend to an affiliate would be detrimental to an insurance
subsidiary's  policyholders  or creditors, because of the financial condition of
the  insurance  subsidiary  or  otherwise, the regulators may block dividends to
affiliates  that  would  otherwise  be  permitted  without  prior  approval.

     Our subsidiaries are permitted under the terms of our indebtedness to incur
additional  indebtedness  that  may  restrict  or  prohibit  the  making  of
distributions,  the  payment  of  dividends  or  the  making  of  loans  by  our
subsidiaries  to  us.  We  cannot  assure  you that the agreements governing the
current and future indebtedness of our subsidiaries will permit our subsidiaries
to provide us with sufficient dividends, distributions or loans to fund payments
on  these  notes  when  due.

Although  we  have  paid  cash  dividends in the past, we may not be able to pay
cash  dividends  in  the  future.

     We  have  a history of paying dividends to our shareholders when sufficient
cash  is  available. However, future cash dividends will depend upon our results
of  operations,  financial  condition,  cash  requirements  and  other  factors,
including  the  ability  of  our subsidiaries to make distributions to us, which
ability  is restricted in the manner previously discussed in this section. Also,
there  can  be  no  assurance that we will continue to pay dividends even if the
necessary  financial  conditions are met and if sufficient cash is available for
distribution.

If  we  lose  our  key  personnel  our  business  could  be  adversely affected.

     The success of our business is dependent, to a large extent, on our ability
to  attract and retain key employees, in particular our senior officers, and key
management,  sales,  information  systems,  underwriting,  claims  and corporate
personnel.  Competition to attract and retain key personnel is intense. Although
we  have change of control agreements with a number of key


Page 23 (I-19)

managers,  in  general,  we do not have employment contracts or non-compete
arrangements  with,  or  key person insurance covering, our employees, including
our key employees.

Applicable  insurance  laws  and  certain  provisions  in  our  certificate  of
incorporation  make  it  difficult to effect a change of control of our Company,
and  a large shareholder may have significant influence over potential change of
control  transactions,  which  could  affect  our  share  value.


     Under  applicable insurance laws and regulations of the states in which our
subsidiaries  are  domiciled,  no  person  may acquire control of us unless that
person has filed a statement containing specified information with the insurance
commissioner  of  each  state and obtains advance approval for such acquisition.
Under  applicable  laws  and  regulations,  any  person  acquiring,  directly or
indirectly (by revocable proxy or otherwise), 10% or more of the voting stock of
any  other  person  is  presumed  to have acquired control of such person, and a
person  who  beneficially  acquires  10%  or  more  of  our common stock without
obtaining  advance approval of the insurance commissioner of each state would be
in  violation  of  applicable  insurance laws and would be subject to injunctive
action requiring disposition or seizure of the shares and prohibiting the voting
of such shares, as well as other action determined by the insurance commissioner
of  each  such  state.

     In  addition,  many  state insurance laws require prior notification to the
state insurance department of a change of control of a non-domiciliary insurance
company  licensed  to  transact  insurance  in  that  state.  Although  these
pre-notification  statutes  do  not authorize the state insurance departments to
disapprove the change of control, they authorize regulatory action - including a
possible  revocation  of our authority to do business - in the affected state if
particular  conditions  exist  such  as  undue  market concentration. Any future
transactions  that  would constitute a change of control of us may require prior
notification  in  the  states  that  have  pre-acquisition  notification  laws.

     As  of December 31, 2004, the Mutual Company owned approximately 56% of our
outstanding  common  stock. The Mutual Company's stock ownership and ability, by
reason  of  such  ownership,  to  elect our board of directors, provides it with
significant  influence  over  potential  change  of  control  transactions.

  Finally,  our  certificate  of incorporation permits our board of directors to
issue  up  to one million shares of preferred stock having such terms, including
voting  rights,  as  the  board  of  directors  shall  fix  and  determine.

                                USE  OF  PROCEEDS

     The proceeds to the Company from sales of Common Stock pursuant to the Plan
will  be  used  for  general  corporate  purposes,  including  investment in and
advances  to  the  Company's  subsidiaries.

PART  II

                     INFORMATION  NOT  REQUIRED  IN  PROSPECTUS

ITEM  14.  OTHER  EXPENSES  OF  ISSUANCE  AND  DISTRIBUTION

         Not  applicable.

ITEM  15.  INDEMNIFICATION  OF  DIRECTORS  AND  OFFICERS

     Our Certificate of Incorporation and Bylaws contain provisions permitted by
the  Delaware  General  Corporation  Law ("DGCL") (under which we are organized)
that  provide that our directors and officers will be indemnified by the Company
to  the  fullest  extent permitted by law for all losses that may be incurred by
them  in connection with any action, suit or proceeding in which they may become
involved  by  reason  of  their service as a director or officer of the Company.
Under  Section  145  of  the  DGCL,  a  corporation  has  the power to indemnify
directors  and  officers  under  certain prescribed circumstances and subject to
certain  limitations  against  certain  costs and expenses, including attorney's
fees  actually  and  reasonably  incurred in connection with any action, suit or
proceeding,  whether  civil, criminal, administrative or investigative, to which
any  of  them  is  a  party  by  reason  of  being  a director or officer of the
corporation if it is determined that the director or officer acted in accordance
with  the  applicable standard of conduct set forth in such statutory provision.

     In addition, our Certificate of Incorporation contains provisions permitted
by  the  DGCL  that  limit  the  monetary liability of our directors for certain
breaches  of their fiduciary duty, and our Bylaws provide for the advancement by
us  to  directors and officers of expenses incurred by them in connection with a
proceeding  of  a type to which the duty of indemnification applies. We maintain
directors'  and  officers'  liability  insurance  to  insure  our  directors and
officers  against  certain  liabilities  incurred  in  their  capacity  as such,
including claims based on breaches of duty, negligence, error and other wrongful
acts.

ITEM  17.  UNDERTAKINGS

(a)  The  undersigned  registrants  hereby  undertake:

     (1)  To  file, during any period in which offers or sales are being made of
securities  registered  hereby,  a post-effective amendment to this registration
statement:

          (i)  to  include  any  prospectus  required  by Section 10(a)(3)of the
          Securities  Act  of  1933;

          (ii)  to  reflect  in  the  prospectus  any  facts  or  events arising
          after  the  effective  date of the registration statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in  the  registration  statement.  Notwithstanding  the foregoing, any
          increase  or  decrease  in  volume of securities offered (if the total
          dollar  value  of  securities  offered would not exceed that which was
          registered)  and  any  deviation  from  the  low  or  high  end of the
          estimated  maximum  offering  range  may  be  reflected in the form of
          prospectus  filed with the Securities and Exchange Commission pursuant
          to  Rule  424(b) if, in the aggregate, the changes in volume and price
          represent  no  more  than a 20 percent change in the maximum aggregate
          offering  price  set  forth  in  the "Calculation of Registration Fee"
          table  in  the  then-effective  registration  statement;

          (iii)  to  include  any  material  information  with  respect  to  the
          plan  of  distribution  not  previously  disclosed in the registration
          statement  or  any  material  change  to  such  information  in  the
          registration  statement;

provided,  however,  that  paragraphs  (i),  (ii)  and  (iii) above do not apply
if  the  information  required  to  be included in a post-effective amendment by
those  paragraphs  is  contained  in  periodic  reports filed by the registrants
pursuant  to  Section 13 or Section 15(d) of the Securities Exchange Act of 1934
that  are  incorporated  by  reference  in  this  registration  statement.

          (2)  That,  for  the  purpose  of  determining any liability under the
          Securities  Act  of  1933, each such post-effective amendment shall be
          deemed  to  be a new registration statement relating to the securities
          offered herein, and the offering of such securities at that time shall
          be  deemed  to  be  the  initial  bona  fide  offering  thereof.

          (3)  To  remove  from  registration  by  means  of  a  post-effective
          amendment  any  of the securities being registered which remain unsold
          at  the  termination  of  the  offering.

Page 31 (II-3)

     (b)  The  undersigned  registrants  hereby  undertake that, for purposes of
     determining  any liability under the Securities Act of 1933, each filing of
     the  registrant's  annual report pursuant to Section 13(a) or Section 15(d)
     of  the Securities Exchange Act of 1934 (and, where applicable, each filing
     of  an  employee  benefit plan's annual report pursuant to Section 15(d) of
     the  Securities  Exchange Act of 1934) that is incorporated by reference in
     the  registration  statement  shall  be  deemed  to  be  a new registration
     statement  relating  to  the securities offered herein, and the offering of
     such  securities  at  that time shall be deemed to be the initial bona fide
     offering  thereof.

     (c)  Insofar  as  indemnification  for  liabilities  arising  under  the
     Securities  Act  of  1933  may  be  permitted  to  directors,  officers and
     controlling persons of the registrant pursuant to the foregoing provisions,
     or  otherwise,  the  registrant has been advised that in the opinion of the
     Securities  and  Exchange Commission such indemnification is against public
     policy  as  expressed  in  the Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other than
     the  payment  by the registrant of expenses incurred or paid by a director,
     officer  or  controlling person of the registrant in the successful defense
     of any action, suit or proceeding) is asserted by such director, officer or
     controlling  person in connection with the securities being registered, the
     registrant  will,  unless in the opinion of its counsel the matter has been
     settled  by  controlling  precedent,  submit  to  a  court  of  appropriate
     jurisdiction  the  question  whether  such indemnification by it is against
     public  policy  as  expressed  in the Act and will be governed by the final
     adjudication  of  such  issue.

     (d)  The  undersigned  registrants  hereby  undertake  that:

          (1)  For  purposes  of  determining  any  liability  under  the
          Securities  Act  of  1933,  the  information  omitted from the form of
          prospectus  filed  as  part of this registration statement in reliance
          upon  Rule  430A  and  contained  in a form of prospectus filed by the
          registrants  pursuant  to  Rule  424(b)(1)  or (4) or 497(h) under the
          Securities  Act  shall  be  deemed  to  be  part  of this registration
          statement  as  of  the  time  it  was  declared  effective;  and

          (2)  For  the  purpose  of  determining  any  liability  under  the
          Securities  Act of 1933, each post-effective amendment that contains a
          form  of prospectus shall be deemed to be a new registration statement
          relating  to  the securities offered therein, and the offering of such
          securities  at  that  time shall be deemed to be the initial bona fide
          offering  thereof.
