    THE  FOLLOWING IS  A SUMMARY OF  CERTAIN INFORMATION  CONTAINED ELSEWHERE IN
THIS PROXY STATEMENT/ PROSPECTUS. THE  INFORMATION CONTAINED IN THIS SUMMARY  IS
QUALIFIED  IN  ITS ENTIRETY  BY, AND  SHOULD  BE READ  IN CONJUNCTION  WITH, THE
DETAILED INFORMATION  AND FINANCIAL  STATEMENTS,  INCLUDING THE  NOTES  THERETO,
APPEARING  ELSEWHERE  IN  THIS  PROXY  STATEMENT/PROSPECTUS  AND  THE  DOCUMENTS
INCORPORATED HEREIN BY REFERENCE.
 
                        PENN TREATY AMERICAN CORPORATION
 
    Penn Treaty American  Corporation ("Penn  Treaty") is  primarily engaged  in
providing  long-term nursing home and home  health care insurance to persons age
65 and over. An originator of long-term nursing home care insurance products for
twenty years,  Penn  Treaty  is  the  second  largest  insurance  carrier  whose
operations  are primarily  focused on long-term  care insurance.  Penn Treaty is
currently licensed to write business in 44 states and the District of  Columbia.
Its  policies are marketed nationally through independent insurance agents. Penn
Treaty underwrites its insurance products through two of its subsidiaries,  Penn
Treaty  Life  Insurance Company,  ("PTLIC") and  Network America  Life Insurance
Company ("Network  America" and  together  with PTLIC,  the "Insurers").  As  of
December  31, 1995,  long-term nursing home  care and home  health care policies
accounted for approximately 93%  of Penn Treaty's  total annualized premiums  in
force.
 
    Penn  Treaty's  principal  products are  individual  fixed,  defined benefit
accident and health insurance policies covering long-term skilled,  intermediate
and  custodial nursing home  care, home health care,  hospital care and policies
that  supplement  Medicare  benefits.  In  1993,  Penn  Treaty  introduced  life
insurance  products designed  specifically for individuals  age 65  and over. In
late 1994, Penn Treaty  introduced an Independent  Living policy which  provides
coverage  over the full term of the policy for services furnished by a homemaker
or companion who is not a qualified or licensed care provider. Available  policy
riders  allow insureds to tailor their  policies and include an automatic annual
benefit increase, benefits for  adult day-care centers and  a return of  premium
benefit.  Policies are  designed to  make the  administration of  claims simple,
quick and sensitive to the needs of senior citizens.
 
    Penn  Treaty's  executive  offices  are  located  at  3440  Lehigh   Street,
Allentown, Pennsylvania and its telephone number is (610) 965-2222.
 
                       HEALTH INSURANCE OF VERMONT, INC.
 
    Health  Insurance of Vermont, Inc.  is engaged in the  marketing and sale of
guaranteed renewable disability income insurance written on an individual basis.
HIVT does  not market  any line  of  insurance other  than accident  and  health
insurance.  Its focus  is on  the marketing  of competitive,  quality disability
insurance in those states in which it is licensed. HIVT is currently licensed to
write business in 46 states and the District of Columbia. HIVT does not maintain
its own sales force  and therefore operates on  a brokerage basis,  distributing
its  products in those states in which it is licensed. All of HIVT's business is
produced by licensed insurance agents who have contracts with HIVT. These agents
may have similar agreements with  other insurance companies and generally  write
insurance for those companies.
 
    HIVT's  executive offices are located  at One Roosevelt Highway, Colchester,
Vermont and its telephone number is (802) 655-5500.
 
                             REASONS FOR THE MERGER
 
    The Board of Directors of  HIVT has determined that  the Merger is fair  to,
and in the best interests of, HIVT and its shareholders and unanimously approved
the Merger Agreement and recommends that HIVT shareholders vote FOR the approval
and adoption of the Merger.
 
                                       6
<PAGE>
    From  time  to time  over  the past  several  years, HIVT  has  reviewed and
reexamined its  business strategies  and  prospects. In  that regard,  HIVT  has
considered  possible  strategic  alliances, combinations  and  transactions with
various industry participants, including companies smaller and larger than HIVT.
 
    Based on that analysis, HIVT's Board of Directors concluded that a strategic
merger, if  on  terms and  conditions  acceptable  to HIVT's  Board  and  HIVT's
stockholders,  could present a valuable opportunity to enhance the stockholders'
investment in HIVT as well as an opportunity to support the continued growth  of
HIVT's business. The terms of the Merger Agreement, including the Exchange Rate,
was  the result of  arms' length negotiations  between HIVT and  Penn Treaty and
their respective representatives. The  HIVT Board consulted  with its legal  and
financial   advisors  and   management  of   HIVT.  After   careful  review  and
consideration, the HIVT Board has determined  that the Merger will provide  fair
value to all HIVT stockholders.

Recommendation of the Board of
 Directors and Reasons for the
 Merger...........................  The Board of Directors of  HIVT believes that the  terms
                                    of  the Merger are fair to  and in the best interests of
                                    its  stockholders  and  have  unanimously  approved  the
                                    Merger  Agreement and the related transactions. The HIVT
                                    Board of  Directors  unanimously  recommends  that  HIVT
                                    stockholders  approve  the  Merger  Agreement.  See "The
                                    Merger -- Recommendation of the Board of Directors."
                                    The HIVT  Board of  Directors believes  that the  Merger
                                    will  provide fair  value to  all HIVT  stockholders and
                                    offers  HIVT   opportunities   for  growth   using   the
                                    additional  capital, expertise and distribution channels
                                    available from Penn Treaty. In reaching its decision  to
                                    approve the Merger Proposal, the HIVT Board of Directors
                                    considered  several  factors including:  (a)  the market
                                    value of Penn Treaty Common Stock to be received in  the
                                    Merger  by  HIVT  stockholders; (b)  the  active trading
                                    market and history of Penn Treaty Common Stock; (c)  the
                                    enhanced  long term value to  HIVT of a strategic merger
                                    with a larger, more  diversified insurance company;  (d)
                                    the  opinion of  Advest, Inc.  ("Advest") to  the effect
                                    that, as of March 15, 1996, the transaction was fair  to
                                    the  HIVT stockholders  from a financial  point of view;
                                    (e) the present intention of Penn Treaty to keep  HIVT's
                                    headquarters   in  Colchester,  Vermont;   and  (f)  the
                                    provision for the exchange  of the Merger  Consideration
                                    consisting  of Penn  Treaty Common  Stock in  a tax-free
                                    transaction.
                                    In the event that HIVT  stockholders do not approve  the
                                    Merger  Proposal or if the Merger is not consummated for
                                    any  other  reason,  HIVT  intends  to  continue  as  an
                                    independent  company,  operating on  a  basis consistent
                                    with its historical  operations. HIVT  will continue  to
                                    market  and  issue  disability  insurance  policies  and
                                    intends to continue its selective geographic  expansion,
                                    seeking to spread risks and to enhance its sales volume.

                                    Reasons for the Merger."
Opinions of Financial Advisors to
 the HIVT Board...................  Advest has  delivered its  written opinion  to the  HIVT
                                    Board  of  Directors  dated  March  15,  1996,  that the

                                    Common  Stock was fair from a financial point of view to
                                    the holders of HIVT Common Stock.

                                    no gain or loss  would be recognized  by Penn Treaty  or
                                    HIVT,  and no gain  or loss would  be recognized by HIVT
                                    stockholders on  the portion  of the  consideration  for
                                    HIVT  Common  Stock  consisting  of  Penn  Treaty Common
                                    Stock. Consummation of  the Merger  is conditioned  upon
                                    there being delivered an opinion of counsel prior to the
                                    Closing   to  the   effect  that   HIVT  and   the  HIVT
                                    stockholders will recognize no gain or loss for  federal
                                    income  tax purposes on the portion of the consideration
                                    for HIVT Common Stock  consisting of Penn Treaty  Common
                                    Stock as a result of the consummation of the Merger.
Anticipated Accounting Treatment..  The  Merger will be treated as a purchase for accounting
                                    and  financial  reporting   purposes.  "The  Merger   --
                                    Anticipated Accounting Treatment."
Interests of Certain Persons in
 the Merger.......................  In  considering the recommendation of  the HIVT Board of

                                    arrangements.
Risk Factors......................  For  discussion  of  the risk  factors  which  should be
                                    considered carefully by HIVT Stockholders in considering
                                    whether to vote  in favor of  the Merger Agreement,  see
                                    "Risk Factors."

              COMPARATIVE HISTORICAL AND PRO FORMA PER SHARE DATA
 
    The  following summary  presents selected comparative  per share information
(i) for  Penn  Treaty  on  a  historical basis  in  comparison  with  pro  forma
information giving effect to the Merger, and (ii) HIVT on an historical basis in
comparison  with its pro forma equivalent information after giving effect to the
Merger, including the receipt  of the Penn Treaty  Common Stock in exchange  for
the  HIVT Common Stock  in accordance with  the Merger. The  pro forma financial
information  should  be  read  in  conjunction  with  the  historical  financial
statements  of Penn Treaty  and HIVT and the  related notes thereto incorporated
herein by reference or contained elsewhere  herein, and in conjunction with  the
unaudited  pro  forma financial  information appearing  elsewhere in  this Proxy
Statement/Prospectus.
 
    Penn Treaty has never paid any cash  dividends on its Common Stock and  does
not  intend to do so  in the foreseeable future. It  is the present intention of
Penn Treaty to  retain any future  earnings to support  the continued growth  of
Penn  Treaty's  business. Any  future  payment of  dividends  by Penn  Treaty is
subject to the discretion of the Board  of Directors and is dependent, in  part,
on  any dividends  it may receive  as the  sole shareholder of  PTLIC and Senior
Financial Consultants Company,  a wholly-owned  subsidiary of  Penn Treaty,  and
which  PTLIC may in turn receive as the sole shareholder of Network America. The
payment of dividends  by PTLIC  and Network  America, respectively,  is in  turn
dependent  on  a  number of  factors,  including their  respective  earnings and
financial condition, business needs and capital and surplus requirements, and is
also subject to certain regulatory restrictions and the effect that such payment
would have on their ratings by A.M. Best Company. See Item 1, "Business --  A.M.
Best's Rating" and Item 1, "Business -- Government Regulation".
 
    The  following  information is  not necessarily  indicative of  the combined
results of operations or  combined financial position  that would have  resulted
had  the Merger been consummated at the  beginning of the periods indicated, nor
is it necessarily  indicative of the  combined results of  operations in  future
periods or future combined financial position.

                                  RISK FACTORS
 
    IN  ADDITION TO  OTHER INFORMATION  IN THIS  PROXY STATEMENT/PROSPECTUS, THE
FOLLOWING FACTORS  SHOULD BE  CONSIDERED CAREFULLY  IN EVALUATING  THE  PROPOSAL
RELATED TO THE MERGER AGREEMENT TO BE VOTED ON AT THE ANNUAL MEETING.
 
RISKS RELATING TO PENN TREATY
 
    ADEQUACY OF LOSS RESERVES.  The reserves for losses and expenses established
by  Penn Treaty are estimates of amounts needed to pay reported and incurred but
not yet reported claims  and related expenses based  on facts and  circumstances
known  as  of the  time  the reserves  are  established. Reserves  are  based on
historical claims  information,  industry  statistics  and  other  factors.  The
establishment  of appropriate reserves  is an inherently  uncertain process, and
there can be no assurance that the ultimate liability will not materially exceed
Penn Treaty's claim and  policy reserves and have  a material adverse effect  on
Penn Treaty's results of operations and financial condition. Due to the inherent
uncertainty  of estimating  reserves, it has  been necessary, and  may over time
continue to be necessary, to revise estimated future liabilities as reflected in
the Company's reserves for claims and policy expenses.
 
    IMPLEMENTATION OF NEW PRODUCTS.  The introduction of new insurance  products
entails  a  greater risk  of unanticipated  claims  incurred than  products with
respect to which Penn Treaty  has developed significant historical claims  data,
such as long-term nursing home insurance. In order to minimize the risks to Penn
Treaty  associated with  this lack  of historical  claims experience  data, Penn
Treaty generally limits  both the amount  of benefits and  duration of  coverage
available  under new products  until such data  is developed. If  as a result of
actual experience, Penn Treaty  does not meet state  mandated loss ratios for  a
product,  state insurance regulators may require Penn Treaty to reduce or refund
premiums on such product. If, however, losses are greater than anticipated, then
in addition to adjusting its reserve levels as discussed below, Penn Treaty  may
seek  regulatory approval of premium increases. Because this approval process is
time consuming, Penn  Treaty must  attempt to  anticipate the  need for  premium
increases  substantially in advance  of its targeted  date for implementing such
increases. Failure to anticipate the need  for or to secure regulatory  approval
of such increases could have a material adverse effect on Penn Treaty. Moreover,
fluidity  in market competition and regulatory  forces might limit Penn Treaty's
ability to  rely on  historical claims  experience for  the development  of  new
premium rates and reserve allocations.
 
    Penn  Treaty began marketing its home  health care policies as a stand-alone
product during the last seven years and, to date, has experienced a higher  than
expected  number of  claims filed and  longer than expected  duration of claims,
requiring higher levels of reserves and  loss ratios than anticipated with  this
product  line.  In  addition, in  late  1994,  Penn Treaty  began  marketing its
Independent Living policy, a home  health care insurance product which  provides
coverage  over the full term of the policy for services furnished by a homemaker
or companion who is not a qualified  or licensed care provider. Because of  Penn
Treaty's  relatively  limited  claims  experience with  these  home  health care
products, Penn Treaty  may incur  higher than expected  loss ratios  and may  be
required to adjust further its reserve levels with respect to these products.
 
    RECOVERABILITY  OF DEFERRED ACQUISITION COSTS.   In connection with the sale
of its insurance  policies, Penn Treaty  defers and amortizes  a portion of  the
policy  acquisition costs over the related premium paying periods of the life of
the policy. These costs include all expenses directly related to the acquisition
of the  policy,  including  commissions, underwriting  and  other  policy  issue
expenses. The amortization of deferred acquisition costs is determined using the
same projected actuarial assumptions used in computing policy reserves. Deferred
acquisition  costs  can be  affected  by unanticipated  termination  of policies
because, upon such unanticipated termination, Penn Treaty is required to expense
fully the deferred acquisition costs  associated with the terminated policy.  If
these  actuarial assumptions  prove to  be inaccurate,  the result  could have a
material adverse  effect  on  Penn  Treaty's results  of  operations  in  future
periods.
 
                                       14
<PAGE>
    MANDATED  LOSS RATIOS.  The states in which Penn Treaty is licensed have the
authority to change  the minimum mandated  statutory loss ratios  to which  Penn
Treaty  is subject, the manner in which these ratios are computed and the manner
in which compliance with these ratios is measured and enforced. Loss ratios  are
commonly  defined as incurred claims and increases in policy reserves divided by
earned premiums. Most states in which Penn Treaty writes insurance have  adopted
the   loss  ratios  recommended   by  the  National   Association  of  Insurance
Commissioners ("NAIC"). Penn Treaty is unable  to predict the impact of (i)  any
changes in the mandatory statutory loss ratios for individual or group long-term
care  policies to which Penn Treaty may  become subject, (ii) any changes in the
minimum  loss  ratios  for  individual  or  group  long-term  care  or  Medicare
supplement  policies or (iii) any  change in the manner  in which these minimums
are computed or enforced in the future. Penn Treaty has not been informed by any
state that it does not meet mandated minimums, and Penn Treaty believes that  it
is  in compliance with all such minimum ratios.  In the event Penn Treaty is not
in  compliance  with  minimum  statutory  loss  ratios  mandated  by  regulatory
authorities  with respect  to certain policies,  Penn Treaty may  be required to
reduce or refund premiums, which could have a material adverse effect upon  Penn
Treaty.
 
    GOVERNMENT  REGULATIONS.    The  business  of  Penn  Treaty,  including  the
insurance  policies  sold  by  the  Insurers,  is  subject  to  stringent  state
governmental   requirements,  including   those  regarding   licensure,  benefit
structure, payment of dividends, settlement  of claims, capital levels,  premium
increases  and transfer of control of the Insurers. Certain changes in such laws
and regulations could have  a material adverse effect  on the operations of  the
Insurers  and, in turn, on Penn Treaty. Specific developments which could have a
material adverse effect on the operations of the insurance industry include, but
are not  limited  to, possible  rate  rollback legislation  and  legislation  to
control  premiums, policy terminations and other policy terms, including premium
levels. In addition, the administration of  such regulations is vested in  state
agencies which have broad powers and are concerned primarily with the protection
of policyholders.
 
    In  addition,  from time  to time  there are  significant federal  and state
legislative developments with respect to  long-term care and Medicare  coverage.
The  Federal Omnibus  Budget Reconciliation Act  of 1990  required that Medicare
supplement  policies  provide  for   guaranteed  renewability  and  waivers   of
pre-existing  condition  coverage  limitations under  certain  circumstances. In
addition, the NAIC  has recently  adopted model long-term  care policy  language
providing  nonforfeiture benefits and has proposed a rate stabilization standard
for long-term care policies. Among the  proposals currently pending in the  U.S.
Congress are the implementation of certain minimum consumer protection standards
for inclusion in all long-term care policies, including guaranteed renewability,
protection against inflation and limitations on waiting periods for pre-existing
conditions. These proposals would also prohibit "high pressure" sales tactics in
connection with long-term care insurance and would guarantee consumers access to
information  regarding  insurers,  including  lapse  and  replacement  rates for
policies and the percentage  of claims denied.  Other pending legislation  would
permit  premiums paid for  long-term care insurance to  be treated as deductible
medical expenses, with the  amount of the deduction  increasing with the age  of
the  taxpayer. Penn  Treaty cannot  predict with  certainty the  effect any such
proposals, if adopted, or  legislative developments could  have on its  business
and operations.
 
    HIGHLY  COMPETITIVE MARKETS; A.M. BEST B+ RATING.  The markets in which Penn
Treaty competes are highly competitive. Penn Treaty competes with large national
and smaller regional  insurers, as well  as specialty insurers.  Many of  theses
insurers are larger and have greater resources and higher A.M. Best ratings than
Penn  Treaty. A.M.  Best's ratings  are based on  a comparative  analysis of the
financial condition  and  operating  performance  for  the  prior  year  of  the
companies  rated, as determined by their publicly available reports. A.M. Best's
classifications are A++  and A+  (superior), A and  A- (excellent),  B++ and  B+
(very  good), B and  B- (good), C++  and C+ (fair),  and C and  C- (marginal), D
(below minimum standards), E (under  state supervision) and F (in  liquidation).
A.M.  Best's  ratings are  based upon  factors of  concern to  policyholders and
insurance agents and are  not directed toward the  protection of investors.  The
Insurers'  current A.M. Best ratings  are both "B+" (very  good). In addition to
the foregoing,  competition  may take  several  other forms,  including  breadth
 
                                       15
<PAGE>
and  flexibility  of coverage,  pricing and  the quality  and level  of services
provided. Additional competition may result  from changes in Medicare  benefits,
as  well as from the  introduction of products similar  to those offered by Penn
Treaty by  additional  private  insurance carriers.  In  addition,  Penn  Treaty
competes  with other insurance companies for producing agents to market and sell
its products. Over the past three fiscal years, more than half of Penn  Treaty's
premiums  have been derived from sales  of policies in Florida and Pennsylvania.
Competitive changes  in such;  markets  could have  an  adverse effect  on  Penn
Treaty.
 
    AGENT RECRUITMENT; RELIANCE ON MARKETING GENERAL AGENT.  Penn Treaty engages
continuously  in active recruitment and training of independent agents to market
and sell its  products, in part  by frequent presentations  designed to  educate
agents  with respect  to Penn Treaty's  insurance products  and operations. Penn
Treaty also periodically  reviews and terminates  its agency relationships  with
non-producing  or underproducing  agents or agents  who do not  comply with Penn
Treaty's guidelines and policies with respect to the sale of its products. While
Penn Treaty believes  that the  commissions it  pays to  independent agents  are
competitive  with  the commissions  paid  by other  insurance  companies selling
similar policies, there can  be no assurance  that Penn Treaty  will be able  to
continue  to  attract  and  retain  independent  agents  to  sell  Penn Treaty's
products.
 
    Penn Treaty utilizes  marketing general  agents from  time to  time for  the
purpose  of recruiting independent  agents and developing  networks of agents in
various states. Penn Treaty has a marketing general agent ("MA") for purposes of
generating business for  the Insurers  in several  states. This  MA receives  an
overriding  commission on business  written in return  for recruiting, training,
and motivating the independent agents. This MA also functions as a general agent
("GA") for the Insurers in  several states. In the capacity  of MA and GA,  this
agent accounted for 21%, 20% and 18% of the total premiums earned by Penn Treaty
during  1993, 1994 and 1995, respectively. The  loss of the services provided by
this agent as MA and GA could have a material adverse effect upon Penn Treaty.
 
    DEPENDENCE ON SENIOR CITIZEN MARKET.   Penn Treaty's insurance products  are
designed  primarily for sale to persons age  65 and over. Many such persons live
on fixed incomes and,  as such, are highly  sensitive to inflation and  interest
rate  fluctuations which affect  their buying power. In  periods of low interest
rates, renewal premiums on Penn Treaty's  products have decreased. There can  be
no  assurance that adverse economic conditions  or lower interest rates will not
have a  material impact  upon the  ability  of senior  citizens to  afford  Penn
Treaty's products which, in turn, could have a material adverse impact upon Penn
Treaty.
 
    LACK  OF DIVIDENDS.   Penn Treaty has  never paid any  cash dividends on its
Common Stock and does not intend to do so in the foreseeable future. Any  future
payment of dividends by Penn Treaty is subject to the discretion of the board of
Directors  and is dependent, in  part, on any dividends  it may receive from its
subsidiaries. See "Dividend Policy."
 
    RESTRICTIONS ON SUBSIDIARY DIVIDENDS.  Payment of dividends by the  Insurers
is  subject to regulatory  restrictions and will depend  on profits arising from
their  business,  computed  according   to  statutory  formulae.  In   addition,
Pennsylvania  law requires notice of extraordinary  dividends to be given to the
Pennsylvania Insurance Department,  which has the  authority to disapprove  such
dividends.  From time to  time, the NAIC and  various state insurance regulators
consider modifying the methods of determining  the amount of dividends that  may
be paid by an insurance company without regulatory approval.
 
    DEPENDENCE  ON  KEY  PERSONNEL.   The  success  of Penn  Treaty  has largely
depended upon the  efforts of  its senior operating  management, including  Penn
Treaty's  President and founder, Irving Levit, age  66. The loss of the services
of Mr. Levit or one or more of  its key personnel could have a material  adverse
effect on the operations of Penn Treaty. Penn Treaty does not have an employment
agreement  with  Mr.  Levit or  any  of  its other  key  personnel.  Penn Treaty
maintains insurance on  Mr. Levit's life  in an aggregate  amount of  $1,000,000
payable  to Penn Treaty, all of which is  underwritten by Penn Treaty and all of
which is reinsured.
 
                                       16
<PAGE>
    CONTROL BY PRINCIPAL SHAREHOLDER.  The principal shareholder of Penn  Treaty
is  Irving  Levit.  After completion  of  the  Merger, Mr.  Levit  will control,
directly  or  indirectly,  up  to  approximately  26.5%  of  the  Common  Stock.
Accordingly,  Mr. Levit will have the  power to exert significant influence over
the policies and affairs of Penn Treaty.
 
    EFFECT OF  CERTAIN ANTI-TAKEOVER  PROVISIONS.   Penn Treaty's  Restated  and
Amended Articles of Incorporation, the Pennsylvania Business Corporation Law and
the  insurance laws  of states  in which  Penn Treaty  conducts business contain
certain provisions  which  could  delay  or  impede  the  removal  of  incumbent
directors  and could make more difficult a merger, tender offer or proxy contest
involving Penn Treaty,  even if such  a transaction would  be beneficial to  the
interests of the shareholders, or could discourage a third party from attempting
to  acquire control  of Penn Treaty.  In particular, the  classification of Penn
Treaty's Board  of Directors  could have  the  effect of  delaying a  change  in
control of Penn Treaty. In addition, Penn Treaty has authorized 5,000,000 shares
of  Preferred Stock, which  Penn Treaty could  issue without further shareholder
approval and upon such terms and  conditions, and having such rights  privileges
and  preferences, as the  Board of Directors  may determine. Penn  Treaty has no
current plans to issue any Preferred Stock. In addition, Pennsylvania  insurance
laws  and regulations prohibit any person  from acquiring control of Penn Treaty
without the prior approval of the Pennsylvania Insurance Commissioner.
 
    MARKET FOR COMMON STOCK.  Penn Treaty's Common Stock is currently listed  on
The  Nasdaq Stock Market, and its average daily trading volume over the 52 weeks
ended December 31, 1995 was approximately 8,576 shares. While the shares of Penn
Treaty Common Stock to be issued pursuant to the Merger will increase the amount
of stock available for  trading, there can  be no assurance  that a more  active
trading market will develop or, if developed, that it will be maintained.
 
    SHARES  ELIGIBLE FOR  FUTURE SALE.   Following the Merger,  Penn Treaty will
have up  to 7,576,852  shares  of Common  Stock  outstanding. Of  these  shares,
        shares  of Common Stock,  including the shares  issued in this offering,
will generally be freely transferable by  persons other than affiliates of  Penn
Treaty without restriction or further registration under the Securities Act. The
remaining            outstanding shares of  Common Stock may not  be sold in the
absence of  registration  under  the  Securities  Act  unless  an  exemption  is
available,  including the exemption  afforded by Rule 144.  No prediction can be
made as to the effect, if any, that future sales of Penn Treaty Common Stock, or
the availability of Penn Treaty Common Stock  for future sale, will have on  the
market  price of the Penn Treaty Common  Stock issued upon the exercise of stock
options, or the  perception that  such sales  may occur,  which could  adversely
affect prevailing market prices for the Common Stock.
 
    POSSIBLE  VOLATILITY OF STOCK PRICE.  The market price of Penn Treaty Common
Stock could  be subject  to  significant fluctuations  caused by  variations  in
quarterly  operating results, litigation involving the company, announcements by
the company or its competitors, general conditions in the insurance industry and
other factors. The stock  market in recent years  has experienced extreme  price
and  volume fluctuations that  often have been  unrelated or disproportionate to
the operating performance of publicly traded companies. These broad fluctuations
may adversely affect the market price of Penn Treaty Common Stock.
 
RISKS RELATING TO HIVT
 
    ADEQUACY OF LOSS RESERVES.   HIVT maintains reserves  based on estimates  of
amounts  needed to pay reported and unreported claims. Reserves do not represent
an exact  calculation of  liabilities, but  rather are  estimates of  what  HIVT
expects  the ultimate  payment and administration  of claims will  cost based on
facts and  circumstances  then  known,  estimates of  future  trends  in  claims
frequency and severity and other factors.
 
    HIGHLY  COMPETITIVE MARKETS;  BEST'S A- RATING.   The markets  in which HIVT
competes are  very  competitive. In  those  markets, HIVT  competes  with  large
national  and smaller regional  insurers, as well  as specialty insurers. Within
these  markets,  ratings  have  become  an  increasingly  important  factor   in
establishing   the   competitive   position  of   insurance   companies.  Rating
organizations review
 
                                       17
<PAGE>
the financial performance  and condition  of insurers, including  that of  HIVT.
Penn  Treaty's rating  of B+  is below  that of  HIVT (A-).  As a  result of the
Merger, HIVT's rating is  likely to be reduced.  Such a reduction may  adversely
affect HIVT's ability to market and sell its products, although such a reduction
is not expected to have a material and adverse impact on Penn Treaty, taken as a
whole.
 
    LIMITED  MANAGEMENT DEPTH.  Largely as a  function of its size, HIVT depends
heavily on the expertise  and abilities of its  senior management personnel  and
does  not have the depth in various  management positions which a larger concern
may possess. As a result, any material and adverse events with respect to any of
its personnel, including  voluntary departures for  other employment  positions,
could seriously and adversely affect HIVT.
 
    NEW  PRODUCTS;  GEOGRAPHIC  DIVERSIFICATION.    As  part  of  its  operating
philosophy, HIVT  has  periodically  attempted to  increase  its  activities  in
several  states, including  California. However,  its claims  experience in that
state has been  higher than anticipated  and has caused  HIVT to reconsider  its
market  focus there,  or to withdraw  from certain areas  entirely. In addition,
HIVT, from time to time, attempts to write disability insurance not available on
a regular basis  from other insurance  carriers. Issuance of  such policies  may
entail  additional  claims risks  over and  above  risks associated  with HIVT's
normal policies.
 
    DIVIDEND RESTRICTIONS.  As a regulated insurance company, HIVT is subject to
certain regulatory limitations on the payment of dividends to its  stockholders.
HIVT  has not paid any dividends since 1990,  when it was determined that it was
necessary to increase its capital surplus  in one jurisdiction in which HIVT  is
licensed.
 
    AGENT  RECRUITMENT;  MARKETING ACTIVITIES.    HIVT's insurance  products are
marketed and sold by a network  of independent insurance agents. In addition  to
independent   agents  HIVT  has  also  developed  a  marketing  network  through
affiliation between HIVT  and agent  networks maintained  by larger  independent
insurance  companies. HIVT may  not be able to  maintain these affiliations upon
completion of the Merger,  and, accordingly, may need  to rely on Penn  Treaty's
distribution   channels  for  its  products.  In  addition,  HIVT's  success  on
attracting agents to sell its policies will depend on the levels of  commissions
it  pays as compared  to the amount  of commissions paid  by insurance companies
selling similar policies. There can be  no assurance that HIVT will continue  to
have  the resources necessary to pay  such commissions and resources to maintain
those relationships in the future.
 
    INVESTMENT  INCOME.    Like  other  insurance  companies,  HIVT  derives   a
significant  amount  of  its  net income  from  its  investment  portfolio. That
portfolio, because of applicable regulatory restrictions, is largely invested in
long term bonds. The level of income generated by such investments will  depend,
in  large part, upon fluctuations in  interest rates and other matters affecting
such investments  which  are  outside the  control  of  HIVT. There  can  be  no
assurance  that HIVT  will be  able to  continue to  make such  investments on a
favorable economic basis in the future.
 
RISKS RELATING TO THE MERGER
 
    NO ASSURANCE OF SUCCESSFUL INTEGRATION  OF CERTAIN OPERATIONS.  Penn  Treaty
and HIVT expect that the Merger will result in certain benefits for the combined
company.  Achieving the anticipated  benefits of the Merger  will depend in part
upon whether the integration  of the two companies'  business is achieved in  an
efficient  and effective manner,  and there can  be no assurance  that this will
occur. The combination of  the two companies will  require, among other  things,
coordination  of the companies' sales and marketing efforts, among others. There
can be no assurance that integration will be accomplished on a timely basis,  if
at  all. The difficulties of such integration  may be increased by the necessity
of coordinating  geographically  separated  organizations.  The  integration  of
certain   operations  following  the  Merger  will  require  the  dedication  of
management resources which may distract  attention from the day-to-day  business
of  the combined company.  Failure to accomplish  effectively the integration of
the two  companies' operations  could have  a material  adverse effect  on  Penn
Treaty's results of operations and financial condition.

    EXCHANGE  RATE WILL NOT FULLY REFLECT CHANGES IN STOCK PRICES.  The relative
stock prices of Penn Treaty Common Stock and HIVT Common Stock at the  Effective
Time  may vary significantly from the prices as  of the date of execution of the
Merger Agreement, the date hereof or the date on which stockholders vote on  the
Merger  due to,  among other  factors, changes  in the  business, operations and
prospects of Penn Treaty or HIVT, market assessments of the likelihood that  the
Merger  will  be  consummated and  the  timing  thereof and  general  market and
economic conditions. The Exchange Rate is subject to adjustment based on changes
in the market value of Penn Treaty Common Stock. However, the Exchange Rate will
not be adjusted to reflect changes in the value of HIVT Common Stock.
 
                                  THE MEETING
 
ANNUAL MEETING
 
    The Annual Meeting  will be held  at                           , Vermont  on
                   ,               , 1996, at 12:00 p.m., and at any adjournment
or postponement thereof.
 
MATTERS TO BE CONSIDERED -- THE MERGER
 
    At the Annual Meeting,  the stockholders of HIVT  will be asked to  consider
and  vote upon the  adoption and approval  of the Merger  Agreement under which,
among other things, Merger Sub would be merged into HIVT with HIVT surviving the
Merger, HIVT would become a wholly owned  subsidiary of Penn Treaty, and all  of
the  outstanding and issued shares of HIVT  Common Stock would be converted into
the right to receive an aggregate of up to approximately 586,768 shares (but not
less than 440,076 shares) of Penn  Treaty Common Stock. Pursuant to the  Merger,
each outstanding share of HIVT Common Stock will be converted into $4.00 in cash
and  up to  1.067 shares (but  not less than  0.8 shares) shares  of Penn Treaty
Common  Stock.  The  Exchange   Rate  is  subject   to  adjustment  in   certain
circumstances  described herein.  See "The Merger  -- Adjustments  to the Merger
Consideration."
 
    The HIVT Board of  Directors has unanimously  approved the Merger  Agreement
and recommends a vote FOR approval of the Merger Agreement.
 
MATTERS TO BE CONSIDERED -- OTHER
 
    At the Annual Meeting, the stockholders of HIVT will also be asked to ratify
and  approve the reimbursement  of certain proxy and  other expenses incurred by
Robert S.W. Leong  and the Committee  to Maximize Shareholder  Value during  the
period  from December 1994 through September 11, 1995 in the aggregate amount of
$54,548. That  reimbursement has  been previously  approved by  HIVT's Board  of
Directors.  In  approving  the  reimbursement of  such  expenses,  the  Board of
Directors determined that Mr. Leong had engaged in proceedings on behalf of  the
shareholders  of HIVT intended to change the  policies of HIVT and in connection
therewith, to elect a new Board of Directors of HIVT. The Board noted that  such
expenses  had  been verified  by  the Treasurer  of  HIVT and  that  the various
proposals submitted by  Mr. Leong to  the shareholders of  the Company had  been
approved  by  the  Company's  shareholders. The  Board  therefore  approved such
reimbursement on  the condition  that its  decision  to do  so be  ratified  and
approved at the next meeting of the shareholders of HIVT. If the shareholders of
HIVT  do not  approve of  such reimbursement  by HIVT,  Mr. Leong  has agreed to
reimburse the Company in full for the amount paid to him for such expenses.
 
    The Board of Directors recommends a vote FOR this proposal.
 
    The Board of Directors having seven members has been authorized as permitted
by HIVT's bylaws. It is proposed to elect two Directors at the Annual Meeting to
replace those Directors whose terms will expire. The Directors so elected  shall
serve  terms  of three  years each  or  until their  successors are  elected and
qualified. In this regard and in connection with the Merger, HIVT has agreed  to
submit  resignations of  its entire  Board of  Directors upon  completion of the
Merger, including the Directors elected at the Annual Meeting.

    MEETINGS  OF THE BOARD OF DIRECTORS AND  COMMITTEES.  The Board of Directors
held four  regular meetings  and eleven  special meetings  during calendar  year
1995.  The Directors also serve on various committees of the Board which include
standing audit, compensation, investment and nominating committees.
 
    The members of  the Audit Committee  during 1995 were  Directors Putnam  and
Beauchamp  (prior  to  September  11,  1995)  and  Directors  Leong  and  Menard
thereafter. The function of the Audit  Committee is to review reports by  HIVT's
Treasurer  and independent accountants and to make recommendations to management
based upon its  review of  these reports,  for improving  or changing  operating
procedures  that it  considers necessary or  desirable. The  Audit Committee met
twice during 1995.
 
    The members of the Compensation and Stock Option Committee during 1995  were
Directors Beauchamp, Brown, Mahoney, Wick and Zais (prior to September 11, 1995)
and  Directors Beauchamp, Kecseg, Mahoney and Savage thereafter. The function of
the Compensation and Stock Option Committee is to periodically review  officers'
salaries  and  consultants' fees  and to  make recommendations  to the  Board of
Directors with  respect  to  adjustments  that  it  considers  appropriate.  The
Committee  also makes recommendations to the  Board of Directors with respect to
the granting of options pursuant to  HIVT's Stock Option Plan. The  Compensation
and Stock Option Committee met three times during 1995.

<PAGE>
    The  members of the  Investment Committee during  1995 were Directors Putnam
and Chadwick  prior to  September 11,  1995), and  Directors Fraser  and  Kecseg
thereafter.  The  function  of the  Investment  Committee is  to  monitor HIVT's
investment portfolio,  with  consideration  of  HIVT's  liquidity  position  and
anticipated  cash requirements. The  Investment Committee met  four times during
1995.
 
    The members of  the Nominating  Committee during 1995  were Directors  Zais,
Brown,  Mahoney and  Sams (prior  to September  11, 1995)  and Directors Fraser,
Leong, Mahoney and Savage thereafter.  The function of the Nominating  Committee
is  to consider and recommend nominees for election to the Board of Directors as
vacancies occur. Shareholders  may make suggestions  for nominees by  submitting
names to the Committee in writing. The Nominating Committee met once during 1995
in such capacity.
 
    The  members  of  the  Nominating  Committee  also  serve  on  the Executive
Committee for HIVT. The Executive Committee considers and makes  recommendations
to  the  Board of  Directors as  to such  matters  as may  be delegated  to such
Committee for consideration by the  Board of Directors. The Executive  Committee
met four times during 1995.
 
    In   connection  with  the   evaluation  of  various   strategic  and  other
relationships by HIVT, the HIVT Board of Directors appointed a special committee
consisting of Directors Mahoney, Leong and Menard, and as special advisor to the
committee, Patrick Hopper, a shareholder of HIVT. The special committee met four
times during 1995.
 
    EMPLOYEES' RETIREMENT PLAN.  Under  HIVT's Employee's Retirement Plan,  upon
normal retirement at age 65, a participant would receive a monthly pension equal
to  the sum of  (a) 1% of  the average of  his highest 60  consecutive months of
earnings within the 120  month period immediately  preceding retirement and  (b)
 .5%  of  the excess  of  the average  of his  highest  60 consecutive  months of
earnings as described  above over  the maximum average  monthly wage  over a  60
month  period ending  at retirement upon  which social security  benefits can be
based multiplied by the participant's years of credited service. For example, an
employee with  35  credited  years  of service  whose  highest  average  monthly
earnings  over a 60  month period was  $2,000 and whose  maximum average monthly
earnings upon which  social security benefits  could be based  was $1,200  would
receive  a monthly pension upon retirement at age 65 of $840 ($2,000 X .01 X 35)
= ($800.00 X .005 X 35). Benefits payable upon early retirement would be lower.
 
    The following table  illustrates the annual  pension benefits payable  under
the  Plan for various representative combinations of pre-retirement remuneration
and years of service classifications, assuming retirement at age 65.

    OTHER PROPOSED ACTIONS.  Pursuant to the  Bylaws, it is proposed to elect  a
secretary  of HIVT to serve a term of one  year or until his or her successor is
elected and  qualified.  It  is  the  intention of  the  persons  named  in  the
accompanying  form  of  proxy  to  vote for  James  L.  Fraser,  the  nominee of
management for the office of secretary for  HIVT. Mr. Fraser has served in  that
capacity since 1995. Mr. Fraser will resign such position at the Effective Date,

    In  the event that,  because of death or  unforeseen disability, the nominee
indicated  above  is  unavailable  for  election,  the  persons  named  in   the
accompanying  form of proxy reserve the right  to vote such proxy for such other
person as may be nominated by the Board of Directors to the office of secretary.
 
    Management knows of  no other  matters which  may properly  come before  the
meeting. However, if any other business should properly come before the meeting,
the  proxies relating  to such  meeting will  be voted  with respect  thereto in
accordance with the best judgment of management.
 
    Stockholders' proposals for the 1997 Annual Meeting must be received by HIVT
at its executive offices  on or before  December 31, 1996  for inclusion in  the
1997 proxy materials.

    The  affirmative vote  of the  holders of  two-thirds of  the votes  cast by
Stockholders present, either  in person or  by proxy, at  the Annual Meeting  is
required to approve the Merger Agreement.

RECORD DATE; STOCK ENTITLED TO VOTE
 
    The HIVT Board of Directors has established              , 1996 as the  date
to  determine those record holders of Common  Stock entitled to notice of and to

                                       23
<PAGE>
REVOCATION OF PROXIES
 
    Any holder of HIVT Common Stock has the unconditional right to revoke his or
her  proxy at any time prior to the  voting thereof at the Annual Meeting by (i)
filing a written revocation with  the Secretary of HIVT  prior to the voting  of
such  proxy, (ii) giving  a duly executed  proxy bearing a  later date, or (iii)

at the Annual Meeting will not itself revoke his or her proxy.
 
SOLICITATION OF PROXIES
 
    Solicitation  of proxies for use at the Annual Meeting may be made in person
or by mail,  telephone, telecopy or  telegram. HIVT  will bear the  cost of  the
solicitation  of proxies from  its stockholders. In  addition to solicitation by
mail, the directors,  officers and employees  of HIVT may  solicit proxies  from
stockholders by telephone or telegram or in person. Such directors, officers and
employees will not be compensated for such solicitation. HIVT has requested that
banking  institutions,  brokerage  firms,  custodians,  trustees,  nominees  and
fiduciaries forward  solicitation materials  to the  beneficial owners  of  HIVT
Common Stock held of record by such entities, and HIVT will, upon the request of
such  record holders,  reimburse reasonable  forwarding expenses.  HIVT does not
anticipate that it will incur any fees, except as set forth in this paragraph.
 
    HIVT STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXY CARDS.
 
                                   THE MERGER
 
MERGER CONSIDERATION
 
    Pursuant to the  Merger Agreement, at  the Effective Time,  Merger Sub  will
merge  into HIVT  and each  share of  HIVT Common  Stock issued  and outstanding
immediately prior to the Effective Time (other than shares of HIVT Common  Stock
owned  by HIVT as treasury  stock and shares of HIVT  Common Stock owned by Penn
Treaty, Merger Sub or any wholly owned  subsidiary of Penn Treaty or HIVT to  be
canceled  in accordance with the Merger Agreement) shall be converted into $4.00
of cash and up  to 1.067 shares (but  not less than 0.8  shares) of Penn  Treaty
Common Stock. See "Adjustments to Merger Consideration".
 
    Based  upon the capitalization of  Penn Treaty and HIVT  as of May 10, 1996,
immediately after  the  Effective  Time,  the Stockholders  of  HIVT  will  hold
approximately 7.74% of the outstanding Penn Treaty Common Stock.
 
ADJUSTMENTS TO MERGER CONSIDERATION
 
    The  consideration to be issued to each  HIVT stockholder in the Merger will
be $4.00 in cash and that number of shares of Penn Treaty Common Stock which  is
determined  by multiplying  the Exchange  Rate by the  number of  shares of HIVT
Common Stock held by such HIVT  stockholder on the Closing Date (as  hereinafter
defined).  The Exchange  Rate shall  equal the  quotient of  the Base  Price (as
defined below)  divided by  the Final  Price (as  defined below).  Assuming  all
outstanding options to purchase HIVT Common Stock have been exercised, the "Base
Price"  shall mean  $8,801,520 divided  by the number  of shares  of HIVT Common
Stock outstanding  on the  Effective Date.  If all  such options  have not  been
exercised  as of the Effective  Date, the Base Price  shall be reduced by $16.00
for each share of HIVT Common Stock not purchased pursuant to the options  which
remain  outstanding and  unexercised. The "Final  Price" shall  mean the average
closing bid price  of Penn  Treaty Common Stock  on the  Nasdaq National  Market
during  the period comprised of the  twenty consecutive trading days immediately
preceding the fifth business day immediately preceding the Effective Time  (such
period  is hereinafter referred to as the "Measurement Period"), as such closing
bid prices  are published  by  the National  Association of  Securities  Dealers
Automated  Quotation  Service; provided,  however, that  if the  average closing
price of  Penn Treaty  Common Stock,  determined in  accordance with  the  first
clause  of this sentence,  during the Measurement  Period is more  than $.20 per
share higher than  the average  closing bid price  of Penn  Treaty Common  Stock
 
                                       24
<PAGE>
during  the Measurement Period, the Final  Price shall equal the average closing
price per share minus  $.20 per share  but this adjustment  shall not cause  the
Final Price to be reduced to a price per share less than the average closing bid
price  of  Penn Treaty  Common Stock  during the  Measurement Period  (the "Penn
Treaty Value").
 
    If the Penn Treaty  Value is greater  than $20.00 or  less than $15.00,  the
parties  will have the right to either  (a) renegotiate the Exchange Rate or (b)
terminate the Merger Agreement.
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES
 
    The conversion of HIVT Common Stock into Penn Treaty Common Stock will occur
automatically at the Effective Time.
 
    As soon  as practicable  after the  Effective Time,  Registrar and  Transfer
Company  or  another  bank  or  trust  company  designated  by  Penn  Treaty and
reasonably acceptable to HIVT, in its capacity as Exchange Agent (the  "Exchange
Agent"),  will send a transmittal form to each HIVT stockholder. The transmittal
form will contain  instructions with  respect to the  surrender of  certificates
representing HIVT Common Stock to be exchanged for Penn Treaty Common Stock.
 
    HIVT STOCKHOLDERS SHOULD NOT FORWARD HIVT STOCK CERTIFICATES TO THE EXCHANGE
AGENT  UNTIL THEY HAVE RECEIVED TRANSMITTAL  FORMS. HIVT STOCKHOLDERS SHOULD NOT
RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY.
 
    Until the certificates  representing HIVT Common  Stock are surrendered  for
exchange after the consummation of the Merger, holders of such certificates will
not  be paid dividends  on the Penn  Treaty Common Stock  into which such shares
have  been  converted.  When  such  certificates  are  surrendered,  any  unpaid
dividends  will be paid without interest.  For all other purposes, however, each
certificate which represents shares of HIVT  Common Stock at the Effective  Time
will  be deemed to evidence ownership of  the shares of Penn Treaty Common Stock
into which those shares have been converted by virtue of the Merger.
 
    All shares of Penn Treaty Common  Stock issued upon conversion of shares  of
HIVT  Common Stock shall be  deemed to have been  issued in full satisfaction of
all rights pertaining to such shares of HIVT Common Stock.
 
    No fractional shares of Penn Treaty Common Stock will be issued to any  HIVT
stockholder  upon consummation  of the  Merger. For  each fractional  share that
would otherwise be issued, the Exchange Agent will pay by check an amount  equal
to  a pro rata  portion of the average  closing bid price  of Penn Treaty Common
Stock as reported  on the Nasdaq  during the Measurement  Period; provided  that
such average closing bid price is not less than $15.00 or greater than $20.00.
 
NASDAQ LISTING
 
    It  is a condition to the Merger that the shares of Penn Treaty Common Stock
to be issued in the Merger be  authorized for listing on the Nasdaq, subject  to
official notice of issuance.
 
BACKGROUND OF THE MERGER
 
    On  June 27, 1995, HIVT engaged Advest to assist it in identifying potential
business relationships, strategic partnerships  or potential acquirors of  HIVT.
Pursuant to that engagement, HIVT prepared, with Advest's assistance, a detailed
Offering   Memorandum  (the  "Memorandum")  describing  HIVT  and  its  business
activities which was circulated to a number of companies who, upon  solicitation
by  Advest, had expressed an interest in  such a relationship or transaction. In
connection  with  this   process,  each  company   which  received   proprietary
information  concerning  HIVT  was  required  to  enter  into  a confidentiality
agreement pursuant to which the party contacted agreed to keep confidential  all
non-public  information concerning HIVT acquired  in connection with discussions
with members  of  management of  HIVT  and the  due  diligence review  of  HIVT,
including  information disclosed in the Memorandum. HIVT and Penn Treaty entered
into such a confidentiality agreement dated October 17, 1995.
 
                                       25
<PAGE>
    Subsequent to  entering  into  the confidentiality  agreement,  Penn  Treaty
submitted  a  preliminary indication  of interest  in  acquiring the  Company on
October 27, 1995. The consideration consisted solely of common stock.
 
    HIVT's Board of Directors considered the Penn Treaty proposal at its meeting
on October 31,  1995. Because HIVT  had not  yet had an  opportunity to  explore
fully  other potential  indications of  interest pursuant  to its  engagement of
Advest, the HIVT  Board of Directors  determined at that  time that HIVT  needed
more  time  to  consider  other  proposals  expected  to  be  advanced  by other
interested parties.
 
    During its October 31, 1995 meeting, the HIVT Board of Directors appointed a
special committee to pursue potential business transactions through Advest.  The
members  of the committee were Robert S.W.  Leong, John W. Mahoney, David Menard
and Patrick Hopper, a stockholder of HIVT and special consultant to the Board of
Directors.
 
    During the  period October  1995 through  January 1996,  Advest contacted  a
number of potential acquirors of HIVT. Each was invited to submit a bid for HIVT
to  be received on  or before January  20, 1996. During  HIVT's Board meeting of
January 20, 1996, the HIVT Board of Directors considered, with the assistance of
Advest the bids which it had received, including the proposal from Penn  Treaty.
Advest indicated that of the bids received, two bids, including the bid received
from  Penn Treaty, were more favorable than the other bids. Those bids were very
close in financial  terms with  the bid submitted  by the  other party  slightly
higher  than the Penn Treaty  bid. Because of the  closeness of the bids, Advest
was requested to  return to Penn  Treaty and  the other bidder  and solicit  one
final  bid for  consideration at  the HIVT Board  of Directors'  next meeting on
January 31, 1996.
 
    Advest did so and both Penn Treaty and the other party increased their  bids
over  the bids submitted and considered as of January 20, 1996. Although the bid
submitted by the other party remained slightly higher than the bid submitted  by
Penn Treaty in purely financial terms, the HIVT Board of Directors determined to
accept the Penn Treaty bid for the following reasons:
 
    1.  Penn Treaty had substantially completed its due diligence activities and
       it also indicated that the proposed merger agreement prepared by HIVT was
       acceptable  to it, except for changes  necessary to reflect the financial
       terms of its  offer. In addition,  for the reasons  discussed below,  the
       Penn  Treaty proposal could be expected  to have a slightly higher chance
       of regulatory approval. These factors caused the HIVT Board of  Directors
       to conclude that a Penn Treaty merger had a higher probability of closing
       than the other transaction.
 
    2.  The Penn Treaty transaction could be structured to qualify as a tax-free
       merger  transaction  offering  HIVT  stockholders  the  ability  to defer
       payment of  taxes  on  the  portion  of  the  transaction  consisting  of
       consideration in the form of Penn Treaty Common Stock.
 
    3.  The HIVT Board of Directors also relied upon Penn Treaty's statements as
       to  its plans to retain employees of  HIVT in Vermont and maintain HIVT's
       ongoing activities in Vermont, and determined that the Penn Treaty  offer
       provided  a  higher  degree  of likelihood  that  those  activities would
       continue for an additional period of time.
 
    Based on  those  considerations, the  Board  authorized Robert  S.W.  Leong,
Chairman/Chief  Executive Officer, and John  W. Mahoney, President, to negotiate
and execute a  letter of  intent with  Penn Treaty  in accordance  with the  bid
submitted.  Penn Treaty and HIVT executed a letter of intent with respect to the
Merger on February 2,  1996. The letter of  intent was subsequently modified  on
February 27, 1996.
 
    On  February 22, 1996, representatives of HIVT, HIVT's Board and management,
representatives of Advest and representatives of Penn Treaty met at the  offices
of  Penn Treaty, to  conduct a due  diligence examination of  the management and
operations of Penn Treaty.  In addition, counsel for  HIVT and Advest  conducted
other due diligence activities prior to execution of the Merger Agreement.
 
    On  March 8, 1996, the Board of Directors of Penn Treaty approved the Merger
and authorized execution of the Merger Agreement.
 
                                       26
<PAGE>
    HIVT and Penn Treaty executed a definitive Merger Agreement as of March  15,
1996. The Merger Agreement was subsequently modified on May 10, 1996 to increase
the  limits which apply  to the per share  price of the Penn  Treaty stock to be
issued as partial consideration for the HIVT shares from $16 to $18 per share to
$15 to $20 per  share. In connection with  that amendment, the Merger  Agreement
was also changed in other technical respects.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    For  the reasons described under "Reasons for the Merger," the HIVT Board of
Directors  has  unanimously  approved  the  Merger  and  recommends  that   HIVT
STOCKHOLDERS VOTE FOR APPROVAL OF THE MERGER AGREEMENT.
 
REASONS FOR THE MERGER
 
    The Board of Directors of HIVT has determined that the Merger is fair to and
in  the best interests of HIVT and its shareholders and unanimously approved the
Merger Proposal and recommends that HIVT shareholders vote FOR the approval  and
adoption of the Merger.
 
    From  time  to time  over  the past  several  years, HIVT  has  reviewed and
reexamined its  business strategies  and  prospects. In  that regard,  HIVT  has
considered  possible  strategic  alliances, combinations  and  transactions with
various industry participants, including companies smaller and larger than HIVT.
During June 1995, HIVT engaged Advest to assist it in that process. In September
1995, HIVT held a special  shareholders' meeting during which certain  proposals
advanced  by shareholders independent  of the then  incumbent Board of Directors
were approved by the  shareholders. Pursuant to those  proposals, a majority  of
the  then  incumbent  Board of  Directors  was  removed from  office.  The proxy
materials distributed by  the independent shareholders  in connection with  such
proposals   indicated  that  the  shareholders   supported  consideration  of  a
fundamental business change involving HIVT, such  as a merger or combination  of
HIVT with another company.
 
    For  the above reasons, HIVT's Board of Directors concluded that a strategic
merger, if  on  terms and  conditions  acceptable  to HIVT's  Board  and  HIVT's
stockholders,  could present a valuable opportunity to enhance the stockholders'
investment in HIVT as well as an opportunity to support the continued growth  of
HIVT's business. The terms of the Merger Agreement, including the Exchange Rate,
were  the result of arms'  length negotiations between HIVT  and Penn Treaty and
the respective representatives. The HIVT  Board of Directors consulted with  its
legal  and financial advisors  and management of HIVT.  After careful review and
consideration, the HIVT Board of Directors  has determined that the Merger  will
provide sufficient value to all HIVT stockholders.
 
    In  reaching its decision to approve the Merger, the HIVT Board of Directors
considered a number of factors, including the benefits of remaining independent,
and without  assigning  any relative  or  specific  weight, the  HIVT  Board  of
Directors  deemed  the  following factors  to  be persuasive  in  selecting Penn
Treaty's offer for approval:
 
     i. The value  of  the Penn  Treaty  Common Stock  to  be received  by  HIVT
        shareholders   along   with  the   cash   offered  ($20.00   per  share)
        significantly exceeded  the  then  market value  of  HIVT  Common  Stock
        ($15.00 bid and $16.50 asked per share at January 31, 1996);
 
     ii. Because  Penn  Treaty  had  conducted  significant  due  diligence with
         respect to HIVT and had indicated that the Merger Agreement proposed by
         HIVT was acceptable to it with the exception of amendments necessary to
         reflect the  specific  consideration  to  be paid  by  Penn  Treaty  in
         connection  with the  Merger, the  Merger with  Penn Treaty  had a high
         likelihood of closing;
 
    iii. The presentation of HIVT's financial  advisor, Advest, and the  opinion
         of  Advest to the effect that, as  of the date of the Merger Agreement,
         the consideration to  be paid  to HIVT's shareholders  pursuant to  the
         Merger  was fair to holders of HIVT Common Stock from a financial point
         of view;
 
                                       27

     iv. The Merger provides for  the exchange of Penn  Treaty Common Stock  for
         HIVT  Common Stock in a tax-free transaction (except for the portion of
         consideration to be paid in cash); and
 
     v. The acknowledgment  by Penn  Treaty  of its  present intention  to  keep
        HIVT's headquarters in Colchester, Vermont.
 
FAIRNESS OPINION
 
    In  addition to assisting  HIVT in evaluating  potential relationships, HIVT
retained Advest as its financial advisor  to render its opinion with respect  to
the  fairness, from  a financial point  of view,  to the holders  of HIVT Common
Stock, of the  consideration to  be paid to  such stockholders  pursuant to  the
Merger.
 
    Advest  is a nationally  recognized investment bank that  is involved in the
valuation of  businesses and  their securities  in connection  with mergers  and
acquisitions,  negotiated underwritings and valuations for estate, corporate and
other purposes. In connection  with its engagement by  HIVT, Advest has been  or
will  be compensated as follows: (i) $35,000 for advisory fees; (ii) $50,000 for
rendering the fairness opinion  discussed herein; and  (iii) $100,000, plus  one
percent  of the aggregate consideration received by HIVT and/or its Stockholders
upon consummation of the Merger.
 
    In July  1995,  Penn Treaty  consummated  a registered  public  offering  of
2,300,000  shares of Penn Treaty Common Stock  which resulted in net proceeds of
$26,065,000. Advest  served as  a  managing underwriter  for such  offering  and
received usual and customary fees in connection therewith.
 
    Advest  rendered its  oral opinion  to the HIVT  Board on  January 31, 1996,
which it subsequently confirmed in writing, dated as of March 15, 1996, that, as
of the date of such opinion, the consideration to be paid pursuant to the Merger
was fair, from a financial point of view, to the holders of HIVT's Common Stock.
 
    THE OPINION  OF ADVEST  UPDATED AS  OF  THE DATE  OF THIS  PROXY  STATEMENT/
PROSPECTUS,  WHICH  SETS  FORTH  CERTAIN  QUALIFICATIONS  AND  ASSUMPTIONS MADE,
MATTERS CONSIDERED AND  LIMITATIONS ON  THE REVIEWS UNDERTAKEN,  IS ATTACHED  AS
ANNEX  II TO THIS PROXY STATEMENT/PROSPECTUS AND SHOULD BE READ IN ITS ENTIRETY.
THE  SUMMARY   OF   THE   OPINION   OF  ADVEST   SET   FORTH   IN   THIS   PROXY
STATEMENT/PROSPECTUS  IS QUALIFIED IN ITS ENTIRETY  BY REFERENCE TO THE OPINION.
ADVEST'S OPINION SHOULD NOT BE  CONSTRUED BY HOLDERS OF  HIVT COMMON STOCK AS  A
RECOMMENDATION  AS TO HOW  SUCH HOLDERS SHOULD  VOTE AT THE  ANNUAL MEETING. THE
INFORMATION SET FORTH BELOW WAS PROVIDED TO HIVT BY ADVEST AND DESCRIBES,  AMONG
OTHER  THINGS,  FACTORS  WHICH WERE  CONSIDERED  BY  ADVEST IN  ARRIVING  AT ITS
OPINION.
 
    In arriving at  its opinion, Advest  reviewed, among other  things, (1)  the
Merger  Agreement together with  exhibits thereto, and  other publicly available
information concerning HIVT which it believes to be relevant to the inquiry, (2)
financial and operating information with respect to the business operations  and
prospects  of HIVT including annual reports, 10-KSB filings, 10-QSB filings, and
annual and  quarterly statutory  statements,  (3) a  trading history  of  HIVT's
common  shares from 1990 to the present and a comparison of that trading history
with those of companies deemed comparable by Advest, and (4) a comparison of the
financial terms of the Merger with the terms of certain other transactions which
Advest deemed  relevant.  In addition,  Advest  conducted discussions  with  the
management  of  HIVT  concerning  its business  and  operation,  assets, present
condition and future prospects, and undertook such other studies, analyses,  and
investigations as it deemed appropriate.
 
    In light of the fact that Penn Treaty is publicly traded and will be issuing
shares  of its common stock  to the owners of HIVT  Common Stock pursuant to the
Merger,  Advest   reviewed   relevant  information   concerning   Penn   Treaty.
Accordingly,  Advest  reviewed  (1)  financial  and  operating  information with
respect to business operations  and prospects of  Penn Treaty, including  annual
reports
 
                                       28
<PAGE>
and  various filings  made by Penn  Treaty with the  Commission including annual
reports to shareholders, Annual Reports on Form 10-K, Quarterly Reports on  Form
10-Q,  and annual and  quarterly statutory statements, (2)  a trading history of
Penn Treaty common shares from 1990 to present, (3) an analysis of the financial
performance of Penn Treaty as compared to its comparable peer group, and (4)  an
analysis  of the financial  effects of the  Merger, as proposed,  on the balance
sheet and  income  statement  of  Penn Treaty.  In  addition,  Advest  has  held
discussions  with  the management  of Penn  Treaty  concerning its  business and
operations, assets, present  condition and future  prospects and undertook  such
other studies, analyses and investigations as Advest deemed appropriate.
 
    Advest  relied upon the accuracy and completeness of the financial and other
information used in arriving at its opinion without independent verification. In
arriving at its opinion, Advest only conducted a limited physical inspection  of
the properties and facilities of HIVT and of Penn Treaty. Advest did not make or
obtain any evaluations or appraisals of the assets of HIVT or Penn Treaty.
 
    In  connection with  rendering its  opinion dated  January 31,  1996. Advest
advised the HIVT Board  of Directors that it  considered a variety of  financial
analyses,  as summarized below. The discussion of such analyses does not purport
to be a complete  description of the analysis  underlying Advest's opinion.  The
preparation  of a  fairness opinion is  a complex,  analytical process involving
various determinations  as  to the  most  appropriate and  relevant  methods  of
financial  analysis  and  the application  of  those methods  to  the particular
circumstances, and,  therefore,  such  opinion is  not  readily  susceptible  to
summary  description.  Any  estimates  contained in  Advest's  analysis  are not
necessarily indicative of future results  or values, which may be  significantly
more  or less favorable than such estimates.  In arriving at its opinion, Advest
did not attribute any  particular weight to any  analysis or fact considered  by
it,  but rather made qualitative judgments  as to the significance and relevance
of each analysis and factor. Accordingly, Advest believes that its analysis must
be considered as a whole,  and that selecting portions  of such analyses and  of
the  factors  considered by  Advest without  considering  all such  analysis and
factors may create  a misleading or  incomplete view of  the analytical  process
underlying  Advest's opinion.  Analyses relating to  the value  of businesses or
securities do not purport  to be appraisals  or to reflect  the prices at  which
businesses  or securities may be sold.  Accordingly, such analyses and estimates
are inherently  subject to  substantial uncertainty.  The following  discussions
summarizes the selected analyses considered and prepared by Advest and discussed
with  the HIVT Board in connection with its oral opinion rendered on January 31,
1996.
 
    COMPARABLE COMPANY ANALYSIS.  Advest reviewed and analyzed selected earnings
per share, book values  per share, and stock  prices considered as multiples  of
earnings  and book value  per share of  various companies comparable  to HIVT as
follows: Arista Investors Corp., Cotton State Life Insurance Company,  Investors
Heritage  Life  Insurance,  Mid-South  Insurance  Company,  Paul  Revere  Corp.,
Security  National  Financial   Corp.,  Universal   Holding  Corporation,   UNUM
Corporation,  and Westbridge Capital Corporation. Advest used the then effective
bid price for HIVT stock to develop per share comparisons of HIVT's value to the
value of the stock of the  selected comparable companies based on HIVT's  actual
results  for 1993  and 1994,  its estimated  1995 results  adjusted to eliminate
certain non-recurring expenses, its actual September 30, 1995 balance sheet (for
book value purposes) and its projected 1996 results. Advest determined that  the
then  current median  latest 12  months' price/earnings  multiple for comparable
companies was  10.17 times  earnings per  share which  yielded prices  for  HIVT
shares  significantly below the then current bid price of $15.35 for each period
except  for  projected  1996  earnings  per  share,  where  the  difference  was
substantially  reduced. On a book  value per share basis,  HIVT's bid price as a
multiple of its book value was  .99, which exceeded the comparable group  median
of .86.
 
    COMPARABLE  TRANSACTION ANALYSIS.  As the next phase of its analysis, Advest
reviewed  financial  and  market  statistics  derived  from  recent   comparable
transactions.  The  transaction review  included  the acquisition  of Prudential
Reinsurance Holdings, Kentucky Medical Insurance Company, Kemper Corporation and
Victoria Financial Corporation as base transactions. Advest reviewed a number of
other transactions. Based  on that  analysis, Advest concluded  that the  median
acquisition  value for  comparable transactions  as a  multiple of  earnings was
11.84 and the median acquisition value for
 
                                       29
<PAGE>
comparable transactions as  a multiple of  book value was  1.36. Based on  these
multiples, HIVT's stock was valued on a per share basis of $17.52 (based on 1996
projected earnings) and at $21.35 based on its book value.
 
    LIQUIDATION.    Advest  then  proceeded to  explore  with  HIVT's  Board the
possible  scenario  of  liquidating  HIVT.  In  doing  so,  Advest  relied  upon
alternative  means  of valuing  HIVT's  business in  force  provided by  E. Paul
Barnhart, HIVT's consulting actuary. Based  on the assumptions utilized and  the
analyses  prepared by E. Paul Barnhart, the  liquidation value of HIVT per share
was determined to range from $18.47 to $21.84 per share.
 
    ANALYSIS OF  BIDS.   Advest then  analyzed  the bids  submitted by  the  two
bidders  who  had advanced  to the  final  stage in  the process  of potentially
acquiring HIVT. Based on the foregoing factors and analysis, Advest's conclusion
was that both of the bids, including the bid submitted by Penn Treaty, were fair
to the shareholders of HIVT from a financial point of view.
 
EFFECTIVE TIME OF THE MERGER
 
    Upon the terms and conditions of the Merger Agreement and in accordance with
the provisions of Subchapter 3 of Chapter 101 of Title 8 of the Vermont Statutes
Annotated (the "Insurance Merger Statute"), Merger  Sub will be merged with  and
into  HIVT at the  Effective Time. The Merger  will become effective immediately
when the Certificate  of Merger, prepared  and executed in  accordance with  the
relevant  provisions of the Insurance Merger Statute, is issued by the Secretary
of State of the State  of Vermont or at such  time thereafter as is provided  in
the  Certificate of Merger. The filing of the Certificate of Merger will be made
as soon as practicable on or after the Closing.
 
    The Closing shall take place at 10:00 a.m. on a date to be specified by  the
parties,  which shall be no later than the fifth business day after satisfaction
of (or waiver in accordance  with the Merger Agreement)  the latest to occur  of
the  conditions set forth in Article VIII  of the Merger Agreement (the "Closing
Date"), at the offices of Penn Treaty, unless another date or place is agreed to
in writing  by the  parties. See  "The  Merger Agreement  -- Conditions  to  the
Merger."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    In  considering the  recommendation of  the HIVT  Board with  respect to the
Merger Agreement, HIVT stockholders should be aware that certain members of  the
HIVT  Board and management have interests in  the Merger that are in addition to
or different from the interests of HIVT stockholders generally.
 
    BENEFICIAL OWNERSHIP  OF HIVT  COMMON  STOCK BY  DIRECTORS AND  OFFICERS  OF
HIVT.   As of  May 3, 1996, Directors  and executive officers  of HIVT and their
affiliates may be deemed to be  beneficial owners of approximately 7.66% of  the
outstanding HIVT stock. Each of the Directors and executive officers of HIVT has
advised  HIVT that he intends to vote or  direct the vote of all the outstanding
HIVT Common Stock over which he has  voting control in favor of approval of  the
Merger  Agreement. HIVT's Directors and executive  officers will not receive any
benefit in their  capacities as stockholders  of HIVT Common  Stock that  differ
from or is an addition to the benefit received by all other shareholders of HIVT
Common Stock.
 
    JOHN  W. MAHONEY EMPLOYMENT AGREEMENT.   John W. Mahoney, President of HIVT,
entered into an Employment  Agreement with HIVT on  October 31, 1994, which  was
subsequently amended on March 24, 1995. The Agreement, as amended, is for a term
ending  on December  31, 1998,  provided, however,  that the  Agreement shall be
extended for a period ending on the third anniversary of a change in control  of
HIVT.  In addition,  HIVT must  give Mr.  Mahoney notice  of termination  of the
Agreement on or before October  30 of each year  thereafter or the Agreement  is
automatically  extended for an additional year. Under the Agreement, a change in
control includes replacement of a majority  of the Board of Directors in  office
at  HIVT on the date of execution of  the Agreement. A majority of the directors
of HIVT were  replaced by  the shareholders  of HIVT  on September  11, 1995.  A
change  in control under the Agreement also includes approval of a merger by the
stockholders of HIVT. The Agreement does not  specify that its term will not  be
extended more than once upon occurrence of more than one change in control.
 
                                       30
<PAGE>
    In  addition, the Agreement  provides Mr. Mahoney  certain other protections
upon occurrence  of  a  change  in  control.  If  Mr.  Mahoney's  employment  is
terminated  after  a  change  in  control,  or  if  Mr.  Mahoney  terminates his
employment based on the existence of one or more of the following circumstances,
as  determined  by  him  in  good  faith:  (i)  the  assignment  of  any  duties
inconsistent   in  any   respect  with   his  position,   authority,  duties  or
responsibilities as  contemplated by  the Agreement,  (ii) the  transfer of  Mr.
Mahoney  to a location more  than 35 miles from the  current location of HIVT in
Colchester Vermont, or (iii) the requirement that Mr. Mahoney undertake business
travel obligations substantially greater than his obligations immediately  prior
to  the change in control, he will be entitled to be paid all accrued but unpaid
base salary, incentive and  other compensation, and  unused vacation time,  plus
2.99 times his annual base salary.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    HIVT  expects to receive an  opinion, dated as of the  date hereof and as of
the Closing and based on factual representations by HIVT, from Gravel and  Shea,
counsel  to HIVT,  to the  effect that  the Merger  will be  treated for federal
income tax purposes as a reorganization within the meaning of Section 368(a)  of
the  Internal Revenue Code of  1986, as amended (the  "Code"), that Penn Treaty,
Merger Sub and  HIVT will  each be  a party  to that  reorganization within  the
meaning  of Section 368(b) of the Code, that  gain on the exchange, if any, will
be recognized by a Stockholder  of HIVT upon the  exchange of HIVT Common  Stock
for  Penn Treaty Common Stock and  $4.00 of cash to the  extent of the lesser of
(i) the $4.00 in cash or  (ii) the excess of the  fair market value of the  Penn
Treaty  Common Stock and the $4.00 in cash and all other property received by an
HIVT Stockholder  in the  exchange, over  the Stockholder's  basis in  his  HIVT
stock, and that otherwise no gain or loss will be recognized by a Stockholder of
HIVT  as a result of the Merger with  respect to the shares of HIVT Common Stock
converted into Penn Treaty Common Stock (except to the extent such  Stockholders
receive cash in lieu of fractional shares).
 
    An  opinion of counsel is not binding  on the Internal Revenue Service or on
the courts. Therefore, there can be no assurance that the Merger will constitute
a tax-free reorganization or that any  of the favorable tax treatments  pursuant
to  a tax-free reorganization will be available to HIVT Stockholders. Because of
the complexity  of  the  tax  laws  and because  the  tax  consequences  to  any
particular  Stockholder may  be affected by  matters not  discussed herein, each
HIVT Stockholder is advised  to consult his/her own  tax advisor concerning  the
applicable federal, state and local income tax consequences of the Merger.
 
    Assuming  qualification as a tax-free reorganization  under the Code, (i) no
gain or loss will be recognized by  Penn Treaty or its shareholders as a  result
of  the Merger, (ii) no gain  or loss will be recognized  by HIVT, (iii) gain on
the exchange, if  any, will be  recognized by  a Stockholder of  HIVT, upon  the
exchange  of HIVT Common Stock for Penn Treaty Common Stock and $4.00 of cash to
the extent of the lesser of (a) the $4.00 in cash or (b) the excess of the  fair
market value of the Penn Treaty Common Stock and the $4.00 in cash and all other
property  received by  an HIVT Stockholder  over the Stockholder's  basis in his
HIVT stock, but otherwise,  no gain or  loss will be recognized  by HIVT or  its
Stockholders  who receive Penn Treaty Common Stock in the Merger in exchange for
their shares of  HIVT Common Stock  (except, as described  below, to the  extent
such  Stockholders receive cash  in lieu of the  issuance of fractional shares),
(iv) the basis of the shares of Penn  Treaty Common Stock to be received by  the
HIVT Stockholders in the Merger will be equal to the basis of the shares of HIVT
Common Stock surrendered in exchange therefor decreased by the $4.00 received in
the  exchange and  increased by the  amount of  gain, if any,  recognized on the
transaction by the  HIVT Stockholder, (v)  the holding period  of the shares  of
Penn  Treaty Common Stock to be received  by the HIVT Stockholders in the Merger
will include the holding  period of the respective  shares of HIVT Common  Stock
exchanged  therefor, provided that all shares are held as capital assets of HIVT
Stockholders at the Effective Time, and (vi) the payment of cash in lieu of  the
issuance  of fractional shares will  be treated as if  fractional shares of Penn
Treaty Common Stock had been issued in the Merger and then had been redeemed  by
Penn Treaty, so that an HIVT Stockholder will recognize gain or loss measured by
the  difference between the amount of cash received  and his or her basis in the
fractional shares of Penn Treaty Common Stock treated as having been redeemed.

    THE DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY  AND
MAY  NOT  BE APPLICABLE  TO CERTAIN  HIVT STOCKHOLDERS  WHOSE TAX  TREATMENT MAY
DIFFER SIGNIFICANTLY  BECAUSE OF  THEIR PARTICULAR  CIRCUMSTANCES. IT  DOES  NOT
ADDRESS THE STATE, LOCAL OR FOREIGN TAX ASPECTS OF THE MERGER. THE DISCUSSION IS
BASED  ON  CURRENTLY  EXISTING PROVISIONS  OF  THE CODE,  EXISTING  AND PROPOSED
TREASURY REGULATIONS  THEREUNDER AND  CURRENT ADMINISTRATIVE  RULINGS AND  COURT
DECISIONS.  ALL OF THE FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD
AFFECT THE CONTINUING  VALIDITY OF THIS  DISCUSSION. EACH PENN  TREATY AND  HIVT
STOCKHOLDER  SHOULD  CONSULT HIS  OR HER  OWN  TAX ADVISOR  WITH RESPECT  TO THE
SPECIFIC TAX CONSEQUENCES OF THE MERGER TO HIM OR HER, INCLUDING THE APPLICATION
AND EFFECT OF STATE, LOCAL AND FOREIGN TAX LAWS.
 
ACCOUNTING TREATMENT
 
    Penn Treaty intends to account for  the Merger under the purchase method  of
accounting  in accordance with APB No. 16.  Under this method of accounting, the
cost of acquiring all outstanding shares of HIVT Common Stock and the assumption
of all outstanding HIVT Options will be determined by the combined value of  the
cash  and Penn Treaty Common  Stock to be issued at  the Effective Date plus the
direct costs associated with the Merger. Penn Treaty will allocate the  purchase
price  in establishing a  new accounting and reporting  basis for the underlying
acquired assets and liabilities of HIVT based on their estimated fair values  at
the Effective Date.
 
RESALE OF PENN TREATY COMMON STOCK BY AFFILIATES
 
    Penn  Treaty Common Stock to be issued to stockholders of HIVT in connection
with the Merger has been registered under the Securities Act. Penn Treaty Common
Stock received by the stockholders of HIVT upon consummation of the Merger  will
be freely transferable under the Securities Act, except for shares issued to any
person  who may  be deemed  an "Affiliate"  (as defined  below) of  HIVT or Penn
Treaty within the  meaning of Rule  145 under the  Securities Act ("Rule  145").
"Affiliates" are generally defined as persons who control, are controlled by, or
are  under common  control with HIVT  or Penn Treaty  at the time  of the Annual
Meeting  (generally,   directors,   certain   executive   officers   and   major
stockholders).  Affiliates of HIVT or  Penn Treaty may not  sell their shares of
Penn Treaty Common Stock acquired in connection with the Merger, except pursuant
to an effective registration  statement under the  Securities Act covering  such
shares  or in compliance with Rule 145  or another applicable exemption from the
registration requirements of the Securities Act. In general, under Rule 145, for
two years  following the  Effective Time,  an Affiliate  (together with  certain
related  persons) would be entitled  to sell shares of  Penn Treaty Common Stock
acquired  in  connection  with  the  Merger  only  through  unsolicited  "broker
transactions"  or in transactions directly with  a "market maker," as such terms
are defined in Rule  144 under the Securities  Act. Additionally, the number  of
shares  to be sold  by an Affiliate  (together with certain  related persons and
certain persons  acting  in concert)  during  such two-year  period  within  any
three-month  period for purposes of Rule 145 may not exceed the greater of 1% of
the outstanding shares of Penn Treaty Common Stock or the average weekly trading
volume of such stock  during the four calendar  weeks preceding such sale.  Rule
145  would remain available  to Affiliates only if  Penn Treaty remained current
with its information  filings with the  Commission under the  Exchange Act.  Two
years  after the Effective  Time, an Affiliate  would be able  to sell such Penn
Treaty Common Stock without such manner of sale or volume limitations,  provided
that  Penn Treaty was current with its Exchange Act information filings and such
Affiliate was  not then  an Affiliate  of  Penn Treaty.  Three years  after  the
Effective  Time, an Affiliate would  be able to sell  such shares of Penn Treaty
Common Stock without any  restrictions provided such Affiliate  has not been  an
Affiliate of Penn Treaty for at least three months prior thereto.
 
CERTAIN REGULATORY MATTERS
 
    As  conditions  precedent  to the  consummation  of the  Merger,  the Merger
Agreement requires,  among other  things: that  no statute,  rule or  regulation
shall have been enacted by the government (or
 
                                       32
<PAGE>
any governmental agency) of the United States or any state, county, municipality
or other political subdivision thereof that makes the consummation of the Merger
and any other transaction contemplated thereby illegal.
 
    Penn  Treaty and HIVT believe that the Merger does not violate the antitrust
laws and  intend to  resist vigorously  any  assertion to  the contrary  by  the
Federal  Trade Commission ("FTC"), the Department  of Justice ("DOJ") or others.
Any such  resistance could  delay  consummation of  the  Merger, perhaps  for  a
considerable  period. Prior  to the  Merger, the  FTC or  the DOJ  could seek to
enjoin the  consummation of  the  Merger under  the  federal antitrust  laws  or
require  that  Penn  Treaty  or  HIVT divest  certain  assets  to  avoid  such a
proceeding. The FTC or DOJ could  also, following the Merger, take action  under
the  federal antitrust  laws to  rescind the  Merger, to  require divestiture of
assets of either Penn Treaty or HIVT, or to obtain other relief.
 
    Certain persons,  such as  state's attorneys  general and  private  parties,
could challenge the Merger as violative of the antitrust laws and seek to enjoin
the consummation of the Merger and, in the case of private persons, also seek to
obtain  treble damages. There can be no assurance that a challenge to the Merger
on antitrust grounds will not be made or,  if such a challenge is made, that  it
will not be successful. Neither Penn Treaty nor HIVT intends to seek any further
stockholder approval or authorization of the Plan as a result of any action that
it may take to resist or resolve any FTC or other objections, unless required to
do so by applicable law.
 
    The  provisions of Title  8 of the Vermont  Statutes Annotated Sections 3421
through 3434 (the "Insurance  Company Merger Statute")  govern the formation  of
the Merger Sub, and the legal requirements which must be satisfied under Vermont
law  for the  Merger to be  completed. Penn  Treaty must obtain  approval of the
Vermont Department of Banking, Insurance,  and Securities (the "Department")  to
organize the Merger Sub.
 
    In  addition, Articles of Merger with respect to the Merger must be approved
by the Department pursuant to 8  V.S.A. Section 3424. Finally, Penn Treaty  will
also  seek approval of the Merger as a  change in control of HIVT under 8 V.S.A.
Section 3683 since the Merger is, in  substance, an acquisition of HIVT by  Penn
Treaty.  In connection with the above requirements, public hearings must be held
with respect to the formation of the  Merger Sub and the acquisition of HIVT  by
Penn  Treaty. Consummation  of the Merger  is contingent on  obtaining the above
regulatory approvals as well  as any other state  or other regulatory  approvals
necessary to complete the transaction.
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
    Under  the Insurance  Merger Statute, a  shareholder is  entitled to dissent
from, and obtain payment of the fair value of his or her shares, in the event of
a merger  or consolidation.  Following  adoption of  the merger  agreement,  the
insurer  must provide notice  of such adoption  to each shareholder  and file an
affidavit of such notice with the Department. Shareholders then have 30 days  to
object  to the  merger in  writing. The  value of  shares owned  by a dissenting
shareholder is  determined  as of  the  effective date  of  the merger.  If  the
surviving  corporation and the dissenting shareholder agree on such value within
30 days after the effective date, the corporation must pay that amount within 90
days of  the  effective date.  If  no such  agreement  is reached,  the  Vermont
Superior Court with jurisdiction over the insurer's principal place of business,
upon  petition made  within 90  days of the  effective date,  will determine the
value, which must be paid  within 60 days of  such determination. Fair value  is
the  value of the shares just before the corporate action to which the dissenter
objects, excluding  any  change  in  the value  based  on  anticipation  of  the
corporate action.
 
    The  Merger qualifies  as a  transaction as  to which  HIVT stockholders may
exercise dissenter's rights under the Insurance Company Merger Statute.
 
           COMPARISON OF RIGHTS OF HIVT AND PENN TREATY SHAREHOLDERS
 
    Penn  Treaty  and  HIVT  are  incorporated  in  Pennsylvania  and   Vermont,
respectively.  HIVT's stockholders, whose  rights are currently  governed by the
laws of the State of Vermont and by the charter and bylaws of HIVT, will  become
shareholders  of Penn Treaty after consummation  of the Merger, and their rights
will be governed  by Pennsylvania law,  and by  the charter and  bylaws of  Penn
 
                                       33

Treaty. Although it is impracticable to delineate all of the differences between
Pennsylvania  and Vermont corporate  law and all of  the differences between the
provisions of the governing documents of  Penn Treaty and HIVT, set forth  below
is  a summary  comparison of  the rights  of a  shareholder under  Penn Treaty's
Articles of Incorporation (the "Penn Treaty Articles") and Penn Treaty's  Bylaws
(the  "Penn  Treaty  Bylaws"),  on  the  one hand,  and  the  rights  of  a HIVT
stockholder under  HIVT's  Articles of  Association  (the "HIVT  Articles")  and
HIVT's  Bylaws  (the "HIVT  Bylaws"),  on the  other  hand. Such  information is
qualified in its entirety  by reference to the  HIVT Articles, the HIVT  Bylaws,
the  Penn Treaty Articles and  the Penn Treaty Bylaws.  Also included below is a
summary comparison of the rights of a HIVT stockholder under Vermont law, on the
one hand, and the rights of a Penn Treaty shareholder under Pennsylvania law, on
the other hand.
 
CLASSES AND SERIES OF CAPITAL STOCK
 
    PENN TREATY.   The  Penn  Treaty Articles  authorize  Penn Treaty  to  issue
10,000,000  shares of  Penn Treaty  Common Stock,  par value  $.10 ("Penn Treaty
Common Stock"), and 5,000,000 shares of Preferred Stock, par value $1.00  ("Penn
Treaty Preferred Stock"). As of the Record Date, 6,990,084 shares of Penn Treaty
Common Stock are issued and outstanding.
 
    HIVT.   The HIVT  Articles provide that  HIVT may issue  1,000,000 shares of
HIVT Common Stock. As of  the Record Date, 549,095  shares of HIVT Common  Stock
are outstanding.
 
DIRECTOR AND OFFICER LIABILITY AND INDEMNIFICATION
 
    PENN  TREATY.   Pennsylvania  law permits  a corporation  to include  in its
bylaws a provision adopted by the vote of its shareholders which eliminates  the
personal  liability of  directors for monetary  damages for any  action taken or
omitted on  behalf of  Penn Treaty  unless (i)  the directors  have breached  or
failed  to  perform their  duties  and (ii)  the  breach or  failure  to perform
constitutes  self-dealing,  willful  misconduct  or  recklessness.  However,   a
corporation  may not  eliminate personal  liability where  the responsibility or
liability of  a director  is pursuant  to any  criminal statute  or is  for  the
payment of taxes pursuant to local, state or Federal law. The Penn Treaty Bylaws
limit  director  liability  to  the  fullest extent  permitted  by  the  laws of
Pennsylvania.
 
    Pennsylvania law permits a business corporation, unless otherwise restricted
by its bylaws, to indemnify any person involved in any third party or derivative
action by reason of the  person's being or having  been a representative of  the
corporation,  if the person acted in good faith and reasonably believed that his
or her actions were in or not  opposed to the best interests of the  corporation
and,  with  respect to  any  criminal proceedings,  had  no reasonable  cause to
believe that his or her conduct was unlawful. In general, no indemnification  is
allowable in derivative actions where the person has been adjudged liable to the
corporation,  unless and to the extent that  the court finds him or her entitled
to indemnification for expenses incurred. To the extent that a representative of
a business corporation has been successful on the merits or otherwise in defense
of a third party or derivative action, indemnification for expenses incurred  is
mandatory.  The Penn Treaty Bylaws  contain no restriction on  its ability to so
indemnify any person.
 
    HIVT.  Under Vermont law, a corporation may indemnify any current or  former
director against any liability, if, in connection with the act or acts resulting
in  liability, the director: (1) conducted himself or herself in good faith; (2)
the director reasonably  believed (i) in  connection with actions  taken in  the
director's  official  capacity  as  a  director, that  the  conduct  was  in the
corporation's best interest, and  (ii) in all other  cases, that the  director's
conduct  was at least not opposed to the corporation's best interest; and (3) if
the proceeding is brought by a government entity, the director had no reasonable
cause to believe his or her conduct was unlawful, and the director's conduct  is
not  found to  be reckless  or intentionally  unlawful. The  corporation may not
indemnify a director if  the director is  found liable to  the corporation in  a
suit  by the  corporation or  in a  shareholder's derivative  action, or  if the
director is  found liable  based on  receipt  by such  director of  an  improper
personal  benefit.  Indemnification,  where  allowed,  must  be  approved  by  a
resolution of the corporation's directors, which must specifically find that the
appropriate standard  of  conduct has  been  met by  the  director who  will  be
indemnified.  HIVT's bylaws provide indemnification  to directors to the fullest
extent allowed under the Vermont law.
 
                                       34
<PAGE>
    Vermont  law  also  mandates  that,  unless  limited  in  its  articles   of
incorporation, a corporation shall indemnify any director against all reasonable
costs  of any successful defense  of any action brought  against any director in
his or her capacity as a  director. The same indemnification is available  under
Vermont  law for  a corporation's officers,  employees and  agents, again unless
limited by the articles of incorporation. Finally, a director, officer, employee
or agent of the  corporation who is  a party to a  proceeding may request  court
ordered  indemnification.  A court  may order  indemnification if  the director,
officer, employee or agent is entitled to mandatory indemnification, or if he or
she is fairly and reasonably entitled to indemnification in view of all relevant
circumstances, whether or  not any relevant  standard of conduct  had been  met.
However,  if the director, officer,  employee or agent is  found liable for such
claim, the  indemnification  is  limited  to  reasonable  expenses  incurred  in
defending the claim.
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
    PENN  TREATY.   Pennsylvania  law  provides that  a  special meeting  of the
shareholders may be called at any time:  (i) by the board of directors; (ii)  by
shareholders  entitled to cast at  least 20% of the  votes that all shareholders
are entitled to cast at a  particular meeting, unless otherwise provided in  the
articles;  and (iii) by such officers or other persons as may be provided in the
bylaws. The shareholders of a "registered corporation" are not entitled to  call
a  special meeting of the shareholders  unless the shareholder is an "interested
shareholder" who is  calling a special  meeting for the  purpose of approving  a
"business combination".
 
    HIVT.    Special meetings  of stockholders  may  be called  by the  board of
directors or by  any other  person or person(s)  authorized by  the articles  of
incorporation or bylaws to do so, or by the holders of at least 10% of all votes
entitled  to be cast on any issue  if they provide the corporation's secretary a
written demand  for the  meeting, describing  the purpose  or purposes  for  the
meeting.  Notice  of a  special  meeting must  be  provided to  each stockholder
entitled to vote at the  meeting not less than 10  nor more than 60 days  before
the  meeting  date. The  notice must  include  a description  of the  purpose or
purposes for which the meeting is called.
 
ANNUAL MEETING OF SHAREHOLDERS
 
    PENN TREATY.  Under Pennsylvania law, if the annual meeting of  shareholders
for  election of directors  is not called  and held within  six months after the
designated time, any shareholder may call such meeting, at any time thereafter.
 
    HIVT.  Vermont law contains no corresponding provision.
 
DIVIDENDS AND DISTRIBUTIONS
 
    PENN TREATY.   Under Pennsylvania  law, unless otherwise  restricted in  the
bylaws,  the board  of directors may  authorize, and a  business corporation may
pay,  dividends  or  make  other  distributions  to  shareholders.  However,   a
distribution  may not  be made  if, as  a result  of such  distribution: (i) the
corporation would be unable  to pay its  debts as they become  due in the  usual
course  of business; or (ii)  the total assets of  the corporation would be less
than the sum  of its  total liabilities and  (unless otherwise  provided in  the
articles  of incorporation) the amount that  would be needed, if the corporation
were to be dissolved  at the time of  distribution, to satisfy the  preferential
rights of holders of preferred stock.
 
    HIVT.   Vermont law permits a corporation's board of directors to authorize,
and the  corporation to  make,  distributions to  its stockholders,  unless  the
articles  of  incorporation restrict  distributions.  The HIVT  Articles  do not
contain such a restriction. Further, no distribution may be made if, as a result
of the distribution, the corporation would not be able to pay its debts as  they
become  due in the usual  course of business, or  the corporation's total assets
would be less than the sum of its total liabilities plus the amount necessary to
satisfy any stockholders' preferential rights superior to those of  stockholders
receiving the distribution.
 
                                       35
<PAGE>
APPRAISAL/DISSENTERS' RIGHTS
 
    PENN  TREATY.  Pennsylvania  law provides that shareholders  have a right of
appraisal  (I.E.,   the   right  to   dissent   and  obtain   payment   of   the
judicially-determined  "fair value" of  their shares) with  respect to specified
corporate actions, including: (i) a  plan of merger, consolidation, division  or
share   exchange;  (ii)  certain   plans  or  amendments   of  the  articles  of
incorporation in which disparate treatment is  accorded to holders of shares  of
the  same class or series; and (iii) a  sale or transfer of substantially all of
the corporation's assets. Appraisal rights are not provided to holders of shares
of any class that is either listed on a national securities exchange or held  of
record by more than 2,000 shareholders; however, this exception to the provision
of  appraisal rights does not apply in the  case of: (i) a plan under which such
shares are not converted solely into  shares of the acquiring, surviving or  new
corporation,  and  cash  in lieu  of  fractional  shares; or  (ii)  shares  of a
preferred or special class of stock, unless the articles, the plan or the  terms
of the transaction entitle all holders of such class to vote thereon and require
for adoption of the plan the affirmative vote of a majority of the votes cast by
all  holders of shares by all holders of  such class to vote thereon and require
for adoption of the plan the affirmative vote of a majority of the votes cast by
holders of shares of the class. See "The Merger -- Appraisal Rights".
 
    HIVT.  Under the  Insurance Merger Statute, stockholders  have the right  to
dissent  from certain corporate  actions, and obtain  payment of the statutorily
determined fair  value  of  their  shares.  The  corporate  actions  from  which
stockholders  are entitled to dissent are (i) merger; (ii) share exchange; (iii)
sale of  all or  substantially all  of the  corporation's assets;  (iv)  certain
amendments  to the articles of  incorporation; and (v) any  action for which the
articles of  incorporation,  bylaws or  resolution  of the  Board  of  Directors
provide  dissenters  rights  to  shareholders.  See  "The  Merger  --  Rights of
Dissenting Stockholders".
 
SHAREHOLDER APPROVAL OF MERGERS
 
    PENN TREATY.  Under Pennsylvania law,  unless required by the bylaws of  the
corporation  (the Penn Treaty  Bylaws contain no  such requirement), shareholder
approval is not required for a plan of merger or consolidation if: (i) the  plan
does  not alter the status of the corporation as a domestic business corporation
and the shares outstanding prior to the merger or consolidation will continue as
or be converted into identical shares of the surviving or new corporation;  (ii)
prior  to the adoption of  the plan, another corporation that  is a party to the
plan owns  90%  or  more  of  the  outstanding  shares  of  each  class  of  the
corporation; or (iii) no shares of the corporation have been issued prior to the
adoption  of the plan of  merger or consideration by  the board of directors. In
cases where shareholder approval is  required, Pennsylvania law provides that  a
merger  or consolidation shall  be approved by  a majority of  the votes cast by
holders or securities entitled  to vote thereon. The  presence, in person or  by
proxy,  of the  holders of  at least a  majority of  shares entitled  to vote is
necessary to constitute  a quorum  at a meeting  of shareholders  held for  such
purpose.
 
    HIVT.   Vermont insurance law requires the adoption of a plan of merger by a
corporation's board of directors, and the approval of the plan of merger by  its
stockholders. Unless a greater vote is required by the corporation's articles of
incorporation  or  bylaws, a  plan  of merger  for  insurance companies  must be
approved by two-thirds of the votes cast by stockholders entitled to vote at the
meeting at which such merger is considered. Following stockholder approval,  and
further  approved by the corporation's board of directors after a 30 day waiting
period, the plan is considered adopted.
 
STOCK REPURCHASES
 
    PENN TREATY.   Under Pennsylvania  law, a  corporation may  acquire its  own
shares.  A purchase,  redemption or  other acquisition  by a  corporation of its
shares is treated as a distribution by the corporation to or for the benefit  of
its  shareholders and  is subject to  the limitations described  above under the
caption "Dividends and Distributions." If the articles of incorporation  provide
that  shares acquired will  be deemed to  be issued but  not outstanding, unless
otherwise provided in the bylaws, the board of directors may restore any or  all
of   the   previously   issued   shares  of   the   corporation   owned   by  it
 
                                       36
<PAGE>
to the status of  authorized by unissued shares.  Indebtedness of a  corporation
incurred  or issued to a shareholder in redemption of shares is on a parity with
the indebtedness of the corporation  to its general unsecured creditors,  except
to the extent subordinated by agreement.
 
    HIVT.   Vermont  law permits  a corporation to  acquire its  own shares, and
shares so  acquired  are  treated  as authorized  but  unissued  shares.  Unless
prohibited  by the corporation's  articles of incorporation,  shares acquired by
the corporation may be reissued. If  the articles of incorporation prohibit  the
reissue of acquired shares, the number of authorized shares of the corporation's
stock  is reduced by the  number of shares the  corporation has acquired. HIVT's
Articles do not  contain such  a restriction.  A purchase,  redemption or  other
acquisition  by a corporation of its shares  is treated as a distribution by the
corporation to or for  the benefit of  its stockholders, and  is subject to  the
limitations described above under the caption "Dividends and Distributions."
 
REMOVAL OF DIRECTORS
 
    PENN  TREATY.   Under  Pennsylvania law,  unless  otherwise provided  by the
corporation's articles or  bylaws adopted  by the shareholders,  directors of  a
corporation may be removed from office without cause by the vote of shareholders
entitled to elect directors but, unless otherwise provided in the articles, if a
bylaw  of the corporation adopted by  the shareholders provides for a classified
board of directors,  directors generally  may be  removed from  office only  for
cause by the vote of shareholders entitled to vote on the matter.
 
    HIVT.   Unless a corporation's articles  of incorporation permit the removal
of directors only for cause, Vermont law allows a corporation's stockholders  to
remove any director with or without cause. HIVT's articles do not contain such a
restriction.  Stockholders may  only remove a  director at a  meeting called for
that purpose and the notice of the meeting must state that the purpose or one of
the purposes is the removal of the  director. However, if a director is  elected
by  a voting group, only the voting  group's stockholders may vote to remove the
director. A majority of the votes cast  at any meeting considering removal of  a
director  is required to remove a director, unless cumulative voting authorized,
in which case removal is  not effective if the  number of votes against  removal
would  be sufficient to elect the director under cumulative voting. In addition,
upon request of the corporation or at least 10% of any class of stockholders,  a
Vermont Superior Court may remove a director for fraudulent or dishonest conduct
relating  to the corporation or gross  abuse of authority or discretion relating
to the corporation if removal is in the best interest of the corporation.
 
CHARTER AMENDMENTS
 
    PENN TREATY.    Under  Pennsylvania  law,  amendments  to  the  articles  of
incorporation  may  be proposed  either  by the  board  of directors  or, unless
otherwise provided in  the corporation's articles,  by shareholders entitled  to
cast  at least  10% of  the votes  that all  shareholders are  entitled to cast.
However, shareholders of a registered corporation are not entitled by statute to
propose an amendment to the articles. Except for certain amendments which do not
require shareholder approval, and unless a greater vote is required,  amendments
of  the articles must be  approved by the affirmative vote  of a majority of the
votes cast by all shareholders  entitled to vote. In  addition, if any class  or
series  of shares  is entitled  to vote as  a class,  the affirmative  vote of a
majority of the votes cast in each such class vote is also required.
 
    HIVT.   Vermont  insurance law  requires  a public  hearing  to be  held  in
connection  with any proposed  amendment to an  insurance company's charter. The
Department must find that the amendment will not be detrimental to policyholders
and those having an interest in the company. Stockholder approval is governed by
the company's articles of association, and,  if there is no such provision,  the
affirmative  vote  of  three-fourths or  the  stockholders entitled  to  vote is
required. Vermont law does not provide stockholders with a method by which  they
can  approve amendments to the articles of incorporation without approval by the
board of directors.
 
                                       37
<PAGE>
STOCKHOLDER ACTION WITHOUT A MEETING
 
    PENN TREATY.  Pennsylvania law requires the unanimous written consent of the
shareholders to  authorize  any  action  without  a  meeting,  unless  otherwise
restricted  by the bylaws.  An action may  be authorized by  less than unanimous
written consent of the  shareholders of a registered  corporation, if less  than
unanimous  consent is permitted by its articles. The Penn Treaty Articles permit
action by less than unanimous consent.
 
    HIVT.   Unless  prohibited by  a  corporation's articles  of  incorporation,
Vermont  law  allows  any  action  required  or  permitted  to  be  taken  at  a
shareholders' meeting,  to  be  taken  without a  meeting  if  all  shareholders
entitled  to vote  on the  action consent  in writing  to the  actions taken. In
addition, if  the articles  of incorporation  specifically provide  and if  each
shareholder  receives prior notice  of the proposed action,  action may be taken
without a  meeting  upon  the  written  consent of  a  simple  majority  of  the
corporation's  shareholders  who  are entitled  to  vote on  the  action. HIVT's
Articles of Incorporation do not provide such authority.
 
"ANTI-TAKEOVER" LAWS
 
    PENN TREATY.   The Pennsylvania Business  Corporation Law ("PBCL")  contains
certain  provisions  which (1)  require that  following  any acquisition  by any
person or group  of 20% of  a public corporation's  voting power, the  remaining
shareholders  have the right to receive payment  for their shares, in cash, from
such person or  group in  an amount  equal to the  "fair value"  of the  shares,
including  an  increment  representing a  proportion  of any  value  payable for
control of the corporation; and (2) prohibit for five years, subject to  certain
exceptions,  a "business combination" (which  includes a merger or consolidation
of the corporation or a sale, lease or exchange of assets) with a shareholder or
group of shareholders beneficially owning 20% or more of a public  corporation's
voting power.
 
    The PBCL also contains a provision which provides that, in discharging their
duties,  the board of  directors may, in  considering the best  interests of the
corporation, consider the effects of any action upon any or all groups  affected
by  such  action, including  shareholders,  employees, suppliers,  customers and
creditors of the  corporation, and upon  communities in which  offices or  other
establishments  of the corporation  are located. Pennsylvania  law also contains
provisions to the effect  that directors have no  greater obligation to  justify
their actions, and need not meet any higher burden of proof, in the context of a
potential  or proposed acquisition of control than they do in any other context.
Pennsylvania corporations could  elect not  to be governed  by these  provisions
prior  to July  27, 1990. Penn  Treaty did not  opt out of  such provisions and,
consequently, such provisions are applicable to Penn Treaty.
 
    HIVT.  Vermont law contains no similar provision.

CERTAIN COVENANTS
 
    Prior  to the  Effective Date, unless  Penn Treaty shall  otherwise agree in
writing:
 
        ORDINARY COURSE.  HIVT shall carry on its business in the usual, regular
    and  ordinary  course  in  substantially  the  same  manner  as   heretofore
    conducted,  and  shall use  its reasonable  efforts  to preserve  intact its
    present business organization,  keep available the  services of its  present
    officers  and  employees  and  preserve  its  relationships  with customers,

    or affiliates to  take) any  action to  encourage, solicit  or initiate  the
    submission  of any  Acquisition Proposal (as  defined below),  or (ii) enter
    into any agreement with respect to any Acquisition Proposal. Notwithstanding
    the foregoing, the provisions  contained in the  Merger Agreement shall  not

    makes an unsolicited bona fide written proposal to acquire HIVT pursuant  to
    a  merger, consolidation, share exchange,  purchase of a substantial portion
    of the assets,  business combination  or other similar  transaction, if  the
    Board  of Directors  of HIVT  determines in  good faith,  based as  to legal
    matters on the written advice of  counsel, that such action is required  for
    the  Board of Directors to comply  with its fiduciary duties to stockholders
    imposed by law (the "HIVT Board Fiduciary Duties"), and (ii) complying  with
    Rule  14e-2 of the Exchange Act with  regard to any Acquisition Proposal, if
    applicable. "Acquisition  Proposal" shall  mean  any proposed:  (A)  merger,

<PAGE>
    assets of HIVT; (C) issue, sale,  or other disposition of (including by  way
    of  merger,  consolidation,  share  exchange  or  any  similar  transaction)
    securities (or  options,  rights  or warrants  to  purchase,  or  securities
    convertible  into, such securities)  representing 50% or  more of the voting
    power of  HIVT,  or  (D)  transaction in  which  any  person  shall  acquire
    beneficial  ownership  (as such  term  is defined  in  Rule 13d-3  under the
    Exchange Act), or the right to acquire beneficial ownership, or any  "group"
    (as  such term  is defined  under the Exchange  Act) shall  have been formed
    which beneficially owns or has the right to acquire beneficial ownership, of
    50% or more of the  outstanding HIVT Common Stock.  In the event HIVT  shall
    determine to provide any information to or negotiate with a person or entity
    or  receives any  offer from  such person  or entity  in connection  with an
    Acquisition Proposal, HIVT shall immediately (i) provide Penn Treaty a  copy
    of  all information provided to the person or entity (ii) inform Penn Treaty
    that information is to be provided,  that negotiations are to take place  or
    that  an offer has been  received, as the case may  be, and (iii) furnish to
    Penn Treaty  the  identity of  the  New Party  and,  if an  offer  has  been
    received, a description of the material terms thereof.
 
        NOTICE  OF BREACH.  Each party shall promptly give written notice to the
    other party upon  becoming aware  of the  occurrence or,  to its  knowledge,
    impending  or  threatened  occurrence, of  any  event which  could  cause or
    constitute a breach of any  of its representations, warranties or  covenants
    contained  or referenced  in the Merger  Agreement or  which could adversely
    effect such party,  and will  use its best  efforts to  prevent or  promptly
    remedy the same. No disclosure to, or investigation made by or on behalf of,
    any  party hereto on or before the  Effective Date shall affect or limit the
    representations, warranties  and covenants  of any  party under  the  Merger
    Agreement.
 
ADDITIONAL AGREEMENTS
 
    ACCESS  AND  INFORMATION.   HIVT shall  afford  to Penn  Treaty and  to Penn
Treaty's accountants,  counsel  and  other  representatives,  reasonable  access
during  normal  business hours  (and  at such  other  times as  the  parties may
mutually agree) throughout the period prior to the Effective Date to all of  its
properties,  books, contracts,  commitments, records  and personnel  and, during
such period,  HIVT  shall  furnish  promptly  to  Penn  Treaty  all  information
concerning  its business (including any applications or notifications made to or
by any  governmental  entity),  properties  and personnel  as  Penn  Treaty  may
reasonably  request. In addition, HIVT shall promptly deliver to Penn Treaty all
regulatory reports that are  filed with respect to  HIVT and any  correspondence
between  HIVT on the one  hand and any state  insurance regulatory agency on the
other hand. Penn Treaty shall conduct itself at all times in such a manner so as
not to be disruptive  of the ordinary business  activities of HIVT. Penn  Treaty
shall  hold, and  shall cause  its respective employees  and agents  to hold, in
confidence  all  such  information   in  accordance  with   the  terms  of   the
Confidentiality  Agreement dated October 17, 1995  between Penn Treaty and HIVT.
Penn Treaty  shall afford  to HIVT  and to  its accountants,  counsel and  other
representatives  the same access  it would grant  to a significant institutional
investor provided Penn Treaty were acting reasonably. HIVT shall hold, and shall
cause its respective employees and agents to hold, in confidence all information
obtained pursuant to such access.
 
    REGISTRATION STATEMENT/PROXY STATEMENT.   As promptly  as practicable  after
the  execution of the Merger  Agreement, HIVT and Penn  Treaty shall prepare and
file the  Proxy Statement/Prospectus  and Penn  Treaty and  HIVT shall  use  all
reasonable  efforts to cause  the Registration Statement  to become effective as
soon thereafter as practicable.
 
    STOCK EXCHANGE LISTING.  Penn Treaty shall list on the Nasdaq, upon official
notice of issuance, the Penn  Treaty Common Stock to  be issued pursuant to  the
Merger.
 
    CONSENTS, APPROVALS AND FILINGS.  Penn Treaty and HIVT shall make, and cause
their subsidiaries and affiliates to make, all necessary filings with respect to
the  Merger and  the other  transactions contemplated  hereby including, without
limitation, those  required  under the  HSR  Act,  the Securities  Act  and  the
Exchange Act and the rules and regulations thereunder, under applicable Blue Sky
or  similar securities laws  and under applicable insurance  laws, and shall use
all reasonable efforts to obtain required approvals and clearances with  respect
thereto to (i) comply as promptly as practicable
 
                                       42
<PAGE>
with  all  governmental  requirements applicable  to  the Merger  and  the other
transactions  contemplated  hereby,  and  (ii)  obtain  promptly  all  necessary
permits,  orders and  other consents  of governmental  entities and  consents of
third parties  necessary  for the  consummation  of  the Merger  and  the  other
transactions contemplated hereby.
 
    HSR  ACT.  HIVT and  Penn Treaty shall use,  and shall cause their "ultimate
parent entities" (if  applicable) to use,  their best efforts,  if required,  to
file  by April 15, 1996  notifications under the HSR  Act in connection with the
Merger and the transactions  contemplated hereby and to  respond as promptly  as
practicable  to any inquiries received from the Federal Trade Commission and the
Antitrust Division of the  Department of Justice  for additional information  or
documentation  and to  respond as promptly  as practicable to  all inquiries and
requests received from any state  attorney general or other governmental  entity
in connection with antitrust matters.
 
    COOPERATION.   Subject to the terms  and conditions herein provided, each of
the parties hereto agrees to use all reasonable efforts to take, or cause to  be
taken,  all actions and to do, or cause to be done, all things necessary, proper
or advisable  under  applicable laws  and  regulations to  consummate  and  make
effective  the  transactions contemplated  by  this Merger  Agreement, including
using all  reasonable efforts  to  obtain all  necessary waivers,  consents  and
approvals, to effect all necessary registrations and filings (including, but not
limited  to,  filings under  the HSR  Act and  with all  applicable governmental
entities) and to lift any injunction or  other legal bar to the Merger (and,  in
such  case, to proceed  with the Merger as  expeditiously as possible), subject,
however, to the appropriate vote  of stockholders of HIVT.  In case at any  time
after  the Effective Date any further action  is necessary or desirable to carry
out the purposes of this Merger Agreement, the proper officers and/or  directors
of Penn Treaty, and HIVT shall take all such necessary action.
 
    REORGANIZATION.  Following the Effective Date, Penn Treaty shall conduct its
business,  and shall cause the Surviving Corporation to conduct its business, in
a manner which  would not  jeopardize the characterization  of the  Merger as  a
reorganization  within the meaning  of Section 368(a)(1)(A)  and 368(a)(2)(E) of
the Code. Penn Treaty will provide HIVT with certain factual representations  of
Penn  Treaty, and Penn Treaty  will use its best efforts  to cause Merger Sub to
provide HIVT  with certain  factual representations  of Merger  Sub,  reasonably
requested  by HIVT as necessary to confirm  that Penn Treaty and Merger Sub will
not take any action on or after the Effective Date that would jeopardize the tax
free nature of  the transaction. HIVT  will provide Penn  Treaty and Merger  Sub
with certain factual representations of HIVT reasonably requested by Penn Treaty
as  necessary to  confirm that  HIVT will not  take any  action on  or after the
Effective Date that would jeopardize the tax free nature of the transaction.
 
    INFORMATION IN DISCLOSURE  DOCUMENTS, REGISTRATION STATEMENTS,  ETC..   Penn
Treaty  and HIVT agree that none of the information supplied by it for inclusion
in: (i)  the Registration  Statement, and  (ii) the  Proxy  Statement/Prospectus
will,  at the time it  becomes effective and at  the Effective Date, contain any
untrue statement of a material fact or omit to state any material fact  required
to  be stated therein or  necessary in order to  make the statements therein, in
light of  the circumstances  under which  they are  made, not  misleading.  Penn
Treaty  agrees that  the Registration  Statement will comply  as to  form in all
material respects with the  provisions of the Securities  Act and the rules  and
regulations    promulgated    thereunder.   HIVT    agrees   that    the   Proxy
Statement/Prospectus will comply as  to form in all  material respects with  the
provisions of the Exchange Act and the rules and regulations thereunder.
 
    INDEMNIFICATION.   From and after the  Effective Date, Penn Treaty shall, to
the fullest extent permitted  under applicable law,  indemnify, defend and  hold
harmless  each present and former director and officer of HIVT (individually, an
"Indemnified Party"  and collectively,  the "Indemnified  Parties") against  all
losses, expenses, claims, damages or liabilities, including those arising out of
the  transactions  contemplated  by this  Merger  Agreement  (excluding criminal
liabilities), based in whole or  in part on any  action or omission, except  any
action or omission which was grossly negligent, reckless, wanton or intentional,
occurring  prior to the Effective Date in connection with such person's assigned
responsibilities in serving as an officer or  director of HIVT. In the event  of
any such loss, expense,
 
                                       43
<PAGE>
claim, damage or liability (whether arising before or after the Effective Date):
(i)  Penn Treaty shall pay  the reasonable fees and  expenses of the Indemnified
Party's counsel, provided such counsel is reasonably acceptable to Penn  Treaty,
promptly  after  statements  therefor are  received,  (ii) Penn  Treaty  and the
Indemnified Parties will cooperate in the defense of any such matter, and  (iii)
any  determination required  to be made  with respect to  whether an Indemnified
Party is  entitled  to indemnification  shall  be  made to  the  fullest  extent
permitted under Vermont Law consistent with the standards set forth in the first
sentence of this Section, by independent legal counsel acceptable to Penn Treaty
and  the Indemnified  Party; provided,  however, that  Penn Treaty  shall not be
liable for any settlement  effected without its  written consent (which  consent
shall  not  be unreasonably  withheld). Penn  Treaty agrees  that all  rights to
indemnification existing in  favor of  the directors, officers  or employees  of
HIVT  as provided in HIVT's Articles of Incorporation or Bylaws, as in effect as
of the date  hereof, with  respect to  matters occurring  through the  Effective
Date, shall survive the Merger and shall continue in full force and effect for a
period of six years from the Effective Date.
 
    EMPLOYEE  BENEFITS.  With respect to benefit plans available to employees of
HIVT, for at least one year from and after the Effective Date, Penn Treaty shall
cause the Surviving Corporation to either: (i) maintain all employee benefits of
HIVT, as the case may be, including, without limitation, benefits under employee
benefit plans, policies  and arrangements,  existing on the  Effective Date,  or
(ii)  provide benefits to employees and  former employees, as applicable, of the
Surviving Corporation that are, taken as a whole, substantially equivalent to or
better than the benefits offered  to such persons by HIVT,  as the case may  be,
immediately  prior to the  Effective Date; provided,  however, that neither Penn
Treaty nor the Surviving Corporation shall be required to adopt or maintain  any
plan  or arrangement providing for  the sale of the  Penn Treaty Common Stock or
HIVT Common Stock.
 
TERMINATION, AMENDMENT AND WAIVER
 
    The Merger Agreement may be terminated by the mutual consent of the  parties
or  at any time prior  to the Closing Date, whether  before or after approval by
the stockholders of HIVT or Penn Treaty,  (i) by either HIVT or Penn Treaty,  if
the  Merger is  not completed  by August  31, 1996  for a  reason other  than on
account of delay or  default on the  part of the terminating  party, or (ii)  by
HIVT  if the Merger is enjoined by a final, unappealable court order not entered
at the request  or with  the support  of HIVT  or Penn  Treaty or  any of  their
respective  5%  stockholders,  affiliates or  associates;  if a  proposal  for a
qualifying acquisition transaction is  received or if Penn  Treaty (A) fails  to
perform  in any  material respect  any of its  material covenants  in the Merger
Agreement and (B) does not cure such default in all material respects within  10
days after written notice of such default is given to Penn Treaty by HIVT and by
Penn  Treaty if  HIVT (A) fails  to perform in  any material respect  any of its
material covenants in the Merger Agreement and (B) does not cure such default in
all material respects  within 10 days  after written notice  of such default  is
given to HIVT by Penn Treaty.
 
    The  Merger  Agreement may  not be  amended  except by  action taken  by the
parties' respective Boards  of Directors or  duly authorized committees  thereof
and  then only  by an  instrument in  writing signed  on behalf  of each  of the
parties to the Merger Agreement and in compliance with applicable law. Following
approval of the  Merger Agreement by  HIVT's stockholders, no  amendment may  be
made  to  the Merger  Agreement without  stockholder  approval which  would: (i)
change the conversion ratios set forth  in Section 3.1 of the Merger  Agreement,
(ii)  change the per  share cash consideration  under Section 3.2  of the Merger
Agreement,  or  (iii)   otherwise  materially  affect   the  rights  of   HIVT's
stockholders.
 
    At any time prior to the Effective Time, the parties to the Merger Agreement
may  (a) extend the time for the performance  of any of the obligations or other
acts of the other parties to the Merger Agreement, (b) waive any inaccuracies in
the  representations  and  warranties  contained  therein  or  in  any  document
delivered  pursuant  thereto  and/or  (c)  waive  compliance  with  any  of  the
agreements or conditions contained therein. Any such waiver shall not be  deemed
to  be continuing or to apply to any future obligation or requirement of another
party to the  Merger Agreement.  Any agreement  on the part  of a  party to  the
Merger  Agreement to any such extension or waiver shall be valid if set forth in
an instrument in writing signed on behalf of such party.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
    The  following unaudited  pro forma combined  condensed financial statements
reflect the Merger of Penn Treaty and HIVT. The Merger will be accounted for  as
a  "purchase"  of  HIVT  by  Penn  Treaty  under  generally  accepted accounting
principles. The pro forma combined condensed financial statements are  unaudited
and  combine the operations of Penn Treaty  and HIVT for the year ended December
31, 1995. The pro  forma balance sheet assumes  the Merger occurred at  December
31,  1995. The  pro forma  statement of  income assumes  the Merger  occurred on
January 1, 1995.
 
    The historical financial information of Penn  Treaty as of and for the  year
ended  December  31, 1995,  have  been derived  from  the Penn  Treaty financial
statements which are incorporated by reference herein. The historical  financial
information  of HIVT as  of and for the  year ended December  31, 1995 have been
derived from the HIVT financial  statements which are incorporated by  reference
herein.  The pro forma  financial statements should be  read in conjunction with
the accompanying  notes and  with the  historical financial  statements of  Penn
Treaty  and HIVT included herein or incorporated herein by reference as the case
may be.
 
    The unaudited pro  forma combined condensed  financial statements have  been
included as required by the Commission and are provided for comparative purposes
only.  The pro forma financial statements do not purport to be indicative of the
financial position or operating  results that would have  been achieved had  the
Merger  been consummated as of the date indicated and should not be construed as
representative of future financial position or operating results.
 
    The pro forma financial statements are based upon available information  and
certain   assumptions  that   Penn  Treaty   believes  are   reasonable  in  the
circumstances. Penn Treaty's preliminary allocation of purchase price was  based
upon  the estimated fair  value of assets acquired  and liabilities assumed. The
actual allocation will be  based upon further studies  and valuations as of  the
closing  dates of  the Merger  and, accordingly,  the final  allocations will be
different from the amounts herein.

    on  April 19,  1995, payable to  shareholders of  record on May  3, 1995 and

(4) The Company  adopted Statement  of Financial Accounting  Standards No.  115,
    "Accounting  for  Certain Investments  in  Debt and  Equity  Securities," on
    January 1, 1994. The cumulative effect  of this adoption was an increase  on
    January  1, 1994  in shareholders' equity  of $3,529,000 to  reflect the net
    gain (net of $1,512,000 in  deferred income taxes) on investment  securities
    classified  or available  for sale. As  of December  31, 1994, shareholders'
    equity was decreased by $2,714,000 due to unrealized losses of $4,112,000 in
    the Company's investment portfolio. As  of December 31, 1995,  shareholders'
    equity  was  increased  by $4,056,000  due  to  gains of  $6,146,000  in the
    Company's investment  portfolio. These  increases were  caused primarily  by
    decreases in interest rates.

    unrealized gain  net  of deferred  income  taxes, on  investment  securities
    classified  or available for sale that  were previously carried at amortized
    cost. As  of  December  31,  1994, shareholders'  equity  was  decreased  by

    in   the  Company's   investment  portfolio.   As  of   December  31,  1995,
    shareholders' equity was increased by $282,893, net of deferred income taxes
    due to unrealized gains of  $519,782 in the Company's investment  portfolio.
    These increases were caused primarily by decreases in interest rates.

person who may be deemed underwriters, in addition to the information called for
by the other Items of the applicable form.
 
    The Registrant hereby  undertakes that  every prospectus (i)  that is  filed
pursuant  to the paragraph immediately preceding,  or (ii) that purports to meet
the requirements of section 10(a)(3) of  the Securities Act of 1933, as  amended
(the "Securities Act"), and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement  and will not be used until such amendment is effective, and that, for
purposes of  determining  any liability  under  the Securities  Act,  each  such
post-effective  amendment 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.
 
    Insofar  as indemnification for liabilities arising under the Securities Act
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 Securities 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 against
the Registrant 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  Securities Act  and will  be
governed by the final application of such issue.
 
    The  undersigned  Registrant hereby  undertakes to  respond to  requests for
information that is incorporated  by reference into  the prospectus pursuant  to
Items  4, 10(b), 11, or 13  of this Form, within one  business day of receipt of
such request, and  to send  the incorporated documents  by first  class mail  or
other  equally prompt  means. This  includes information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
    The undersigned  Registrant  hereby  undertakes  to supply  by  means  of  a
post-effective  amendment  all  information concerning  a  transaction,  and the
company being  acquired  involved therein,  that  was  not the  subject  of  and
included in the registration statement when it became effective.

merger  of  a  wholly-owned  subsidiary  of  Parent  to  be  formed  as  soon as
practicable following the execution of this Merger Agreement ("Merger Sub") with
and into the  Company upon the  terms and  subject to the  conditions set  forth
herein (the "Merger").
 
    B.   For Federal income  tax purposes, it is  intended that the Merger shall
qualify as a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code").
 
    C.   For  accounting purposes,  it  is intended  that  the Merger  shall  be
accounted for as a purchase of the Company.
 
                           N O W  T H E R E F O R E,
 
    In   consideration  of  the  foregoing  premises  and  the  representations,
warranties and agreements contained herein,  the parties hereto intending to  be
legally bound agree as follows.

    Section 1.2.    EFFECTIVE DATE  OF  THE MERGER.    The Merger  shall  become

<PAGE>
or otherwise  have forfeited  appraisal  rights (collectively,  the  "Dissenting
Shares")  shall not  be converted  into or  represent the  right to  receive the
consideration described in Section 1.4 above (the "Merger Consideration").  Such
shareholders shall be entitled to receive payment of the appraised value of such
shares  of Company Common Stock held by them in accordance with the VBCA, except
any shareholders who  have failed  to perfect or  shall have  withdrawn or  lost

                              CONVERSION OF SHARES
 
    Section 3.1.  EXCHANGE RATE.
 
    (a) As of the Effective Date, by virtue of the Merger and without any action
on the part of any holder of any shares of the Companys Common Stock, $3.00  par
value ("Company Common Stock"):
 
        (i)  All shares of Company Common Stock which are held by the Company or
    any other subsidiary shall be canceled without any conversion thereof and no
    consideration shall be given with respect thereto.
 
        (ii) Subject to Section 3.5, each remaining outstanding share of Company
    Common  Stock  shall  be  converted  into  the  number  of  fully  paid  and
    nonassessable shares of the Common Stock, $.10 par value, of Parent ("Parent
    Common  Stock") multiplied by  the Exchange Rate (as  defined below) and the
    cash consideration set forth in Section 3.2.
 
       (iii) In the event of any stock dividend, stock split,  reclassification,
    recapitalization,  combination  or exchange  of shares  with respect  to, or
    rights issued in respect of, Parent  Common Stock after the date hereof  and
    prior  to or as of  the Effective Date, the  Exchange Rate shall be adjusted
    accordingly.
 
       (iv) Each issued  and outstanding  share of  Common Stock  of Merger  Sub
    ("Merger  Sub Common  Stock") shall be  converted into and  become one fully
    paid and  nonassessable  share of  Common  Stock,  $.01 par  value,  of  the
    Surviving Corporation.
 
                                       2
<PAGE>
    (b) The Exchange Rate shall mean:
 
        (i)  The quotient of  the Base Price  (as defined below)  divided by the
    Final Price (as defined below).
 
        (ii) Assuming all Company Options (as defined in Section 3.6 below) have
    been exercised, the "Base Price" shall mean $8,801,520 divided by the number
    of shares of Company Common Stock outstanding on the Effective Date. If  all
    Company  Options have not been exercised as  of the Effective Date, the Base
    Price shall reduced  by $16.00 for  each share of  Company Common Stock  not
    purchased  pursuant  to the  Company  Options which  remain  outstanding and
    unexercised.
 
       (iii) The  "Final Price"  shall mean  the average  closing bid  price  of
    Parent  Common  Stock  on  the  Nasdaq  National  Market  during  the period
    comprised of the twenty consecutive  trading days immediately preceding  the
    fifth business day immediately preceding the Effective Date (siuch period is
    hereinafter  referred to as  the "Measurement Period"),  as such closing bid
    prices are reported in THE  WALL STREET JOURNAL, or  if not so published  in
    such  newspaper, in any  other newspaper of  general circulation selected by
    the Company, provided, however, that if the average closing price of  Parent
    Common  Stock,  determined  in  accordance with  the  first  clause  of this
    sentence, during the Measurement Period is  more than $.20 per share  higher
    than  the  average  closing bid  price  of  Parent Common  Stock  during the
    Measurement Period, the Final  Price shall equal  the average closing  price
    per share minus $.20 per share but this adjustment shall not cause the Final
    Price  to be reduced to a price per  share less than the average closing bid
    price of Parent  Common Stock during  the Measurement Period.  If the  Final
    Price  of Parent Common Stock, determined in accordance with the immediately
    preceding sentence, is less than $16.00 or greater than $18.00, this  Merger
    Agreement  shall terminate; provided,  however, that the  parties hereto may
    waive this termination provision in writing.
 
    Section 3.2.   CASH CONSIDERATION  FOR SHARES.   At the  Effective Date,  by
virtue  of the Merger and without any action  on the part of Parent, Merger Sub,
the Company, or the holders of any shares of Company Common Stock: Each share of
Company Common Stock issued and  outstanding immediately prior to the  Effective
Date  (other than any shares of Company  Common Stock to be canceled pursuant to
Section 3.1(a)(i) shall be converted into  the right to receive $4.00 per  share
in  cash (the "Per Share Cash Consideration")  (to be paid in addition to Parent
Common Stock, as described in Section 3.1 hereof). Assuming all Company  Options
(as  defined in Section 3.6 below) have  been exercised, the aggregate amount of
cash consideration  paid for  all  shares of  Company  Common Stock  (the  "Cash
Consideration")  will be Two  Million Two Hundred  Thousand Three Hundred Eighty
Dollars ($2,200,380). If all Company Options  have not been exercised, the  Cash
Consideration  shall be reduced by $4.00 for  each share of Company Common Stock
not  purchased  pursuant  to  the  outstanding  Company  Options  which   remain
outstanding and unexercised.
 
    Section  3.3.   PAYMENT  FOR SHARES  IN THE  MERGER.   The manner  of making
payment for Company Common Stock in the Merger shall be as follows:
 
        (a) On the Effective Date, Parent shall make available to the Company or
    such  other  exchange  agent  as  selected  by  the  Parent  and  reasonably
    acceptable  to the Company  (the "Exchange Agent"), for  the benefit of each
    holder of exercised Company Common Stock and each holder of Company  Options
    (as  defined in  Section 3.6(a)):  (i) a  sufficient number  of certificates
    representing Parent Common Stock required  to effect the delivery of  Parent
    Common  Stock required to  be issued pursuant  to Sections 3.1  and 3.6, and
    (ii) cash in the amount of  the Cash Consideration (such cash, the  "Payment
    Fund")  required  to be  paid pursuant  to Section  3.2. The  Exchange Agent
    shall, pursuant to irrevocable instructions, deliver the Parent Common Stock
    contemplated to be issued and the Per Share Cash Consideration  contemplated
    to be paid pursuant to Sections 3.1 and 3.6.
 
        (b)  Promptly after the Effective Date, the Exchange Agent shall mail to
    each holder of record (as shown on the books of the Companys transfer  agent
    as of the Effective Date) of a
 
                                       3
<PAGE>
    certificate  or certificates which  immediately prior to  the Effective Date
    represented outstanding  shares of  Company  Common Stock  (individually,  a
    "Certificate"  and collectively, the "Certificates") (i) a form of letter of
    transmittal (which shall specify that  delivery shall be effected, and  risk
    of  loss and title to the Certificates shall pass, only upon proper delivery
    of the Certificates to the Exchange Agent) and (ii) instructions for use  in
    effecting  the  surrender of  the  Certificates for  payment  therefor. Upon
    surrender of Certificates for cancellation  to the Exchange Agent,  together
    with such transmittal letter duly executed and any other required documents,
    the  holder of such Certificates shall be entitled to receive for each share
    of the Company Common Stock represented  by such Certificates the number  of
    shares of Parent Common Stock into which such shares of Company Common stock
    are  converted in the Merger  and the Per Share  Cash Consideration, and the
    Certificates  so  surrendered  shall  be  canceled.  Until  so  surrendered,
    Certificates  shall  represent solely  the right  to  receive the  number of
    shares of Parent Common Stock into which such shares of Company Common Stock
    are converted in the Merger, any cash in lieu of fractional shares of Parent
    Common Stock as  contemplated by  Section 3.5 with  respect to  each of  the
    shares  of Company Common  Stock represented thereby and  the Per Share Cash
    Consideration. The Exchange Agent shall not be entitled to vote or  exercise
    any  rights of ownership with respect to  the Parent Common Stock held by it
    from time  to time  hereunder, except  that it  shall receive  and hold  all
    dividends  or other distributions  paid or distributed  with respect to such
    Parent Common Stock for the account of the persons entitled thereto.
 
        (c) Any portion of the Payment  Fund which remains undistributed to  the
    holders  of Company Common Stock for  twelve months after the Effective Date
    shall be delivered to Parent upon demand, and any holders of Company  Common
    Stock  who have not theretofore complied  with this Article shall thereafter
    look only to Parent  for the Cash Consideration  to which they are  entitled
    pursuant   to  this  Article.  If  any  Certificates  shall  not  have  been
    surrendered prior to  five years  after the Effective  Date (or  immediately
    prior  to such earlier  date on which  any Cash Consideration  in respect of
    such Certificate would otherwise  escheat to or become  the property of  any
    government  entity), any cash  or other consideration  payable in respect of
    such Certificate shall, to  the extent permitted  by applicable law,  become
    the  property of the Surviving Corporation, free  and clear of all claims or
    interest of any person previously entitled thereto.
 
        (d) None of  Parent, Merger Sub  or the Surviving  Corporation shall  be
    liable to any holder of shares of Company Common Stock for any cash from the
    Payment  Fund  delivered to  a public  official  pursuant to  any applicable
    abandoned property, escheat or similar law.
 
        (e) Parent  or  the Exchange  Agent  shall  be entitled  to  deduct  and
    withhold from the consideration otherwise payable pursuant to this Agreement
    to  any holder of shares  of Company Common Stock  such amounts as Parent or
    the Exchange Agent is  required to deduct and  withhold with respect to  the
    making  of such payment under the Code,  or any provision of state, local or
    foreign tax law. To the extent that amounts are so withheld and paid over to
    the appropriate  taxing authority  by  Parent or  the Exchange  Agent,  such
    withheld  amounts shall  be treated  for all  purposes of  this Agreement as
    having been paid  to the holder  of the  shares of Company  Common Stock  in
    respect  of which such deduction  and withholding was made  by Parent or the
    Exchange Agent.
 
    Section  3.4.    DIVIDENDS;   TRANSFER  TAXES.     No  dividends  or   other
distributions  that are declared or made on  Parent Common Stock will be paid to
persons entitled  to  receive  certificates  representing  Parent  Common  Stock
pursuant  to  this  Merger Agreement  until  such persons:  (i)  surrender their
Certificates representing Company Common Stock,  or (ii) surrender their  option
award  agreements or provide other satisfactory  evidence of the cancellation of
Company Options, as applicable. Upon such surrender, there shall be paid to  the
person  in whose  name the  certificates representing  such Parent  Common Stock
shall be issued  any dividends or  other distributions which  shall have  become
payable  with respect to  such Parent Common  Stock in respect  of a record date
after the Effective Date. In no event shall the person entitled to receive  such
dividends  be entitled to receive  interest on such dividends.  If any Per Share
Cash Consideration, any  cash in lieu  of fractional shares  or any  certificate
 
                                       4
<PAGE>
representing Parent Common Stock is to be paid to or issued in a name other than
that in which the Certificate surrendered in exchange therefor is registered, it
shall  be a condition of such exchange that the Certificate so surrendered shall
be properly endorsed  and otherwise  in proper form  for transfer  and that  the
person  requesting such exchange shall pay to the Exchange Agent any transfer or
other taxes required by reason of  the issuance of certificates for such  Parent
Common  Stock  in  a  name other  than  that  of the  registered  holder  of the
Certificate surrendered, or shall establish to the satisfaction of the  Exchange
Agent  that such  tax has  been paid or  is not  applicable. Notwithstanding the
foregoing, neither the Exchange Agent nor any party hereto shall be liable to  a
holder  of Company Options or  shares of Company Common  Stock for any shares of
Parent Common Stock or dividends thereon delivered to a public official pursuant
to any applicable escheat laws.
 
    Section 3.5.  NO FRACTIONAL SHARES.   No certificates or scrip  representing
less  than one share of  Parent Common Stock shall  be issued upon the surrender
for exchange of (i) Certificates  representing Company Common Stock pursuant  to
Sections  3.1(b) and 3.2  or (ii) option  award agreements or  other evidence of
cancellation of Company  Options pursuant to  Section 3.6. In  lieu of any  such
fractional  share, each  holder of Company  Common Stock or  Company Options who
would otherwise have been  entitled to a  fraction of a  share of Parent  Common
Stock  upon  surrender of  (i) Certificates  for  exchange pursuant  to Sections
3.1(b)  and  3.2,  or  (ii)  option  award  agreements  or  other  evidence   of
cancellation  of Company Options pursuant to Section 3.6 shall be paid upon such
surrender, cash  (without  interest)  in  an amount  equal  to  such  fractional
interest multiplied by the Final Price (or the Base Price, if the Final Price is
lower  than the  Base Price)  plus an amount  equal to  such fractional interest
multiplied by the Per Share Cash Consideration. As soon as practicable after the
determination of the amount of cash to be paid to former stockholders or  option
holders  of the Company in  lieu of any fractional  interests, Parent shall make
available to  the  Exchange  Agent,  which  shall  in  turn  make  available  in
accordance  with this Merger Agreement, such amounts to such former stockholders
and option holders.
 
    Section 3.6.  STOCK OPTIONS.
 
    Prior to the Effective Date, the Company shall use its best efforts to cause
the holders of each unexpired and  unexercised option (each a "Company  Option")
under  the Company's 1985 Incentive Stock  Option Plan (the "Stock Option Plan")
to exercise such options. At the  Effective Date, Parent shall issue to  holders
of  any unexercised  Company Options  an option  (each a  "Parent Option") under
Parent's employee stock  option plan to  purchase a number  of shares of  Parent
Common  Stock equal to the Exchange Rate  (as defined in Section 3.1(b)) for the
number of shares  of the  Company Common Stock  that could  have been  purchased
under  the Company Option, at a price per  share of Parent Common Stock equal to
the option exercise price determined pursuant  to the Company Option divided  by
the  Exchange Rate. Parent shall, from and after the Effective Date, reserve and
make available for issuance upon exercise of Parent Options all shares of Parent
Common Stock covered thereby and amend  its Registration Statement on Form  S-8,
such  amendment  to be  declared  effective within  twenty  (20) days  after the
Effective Date,  or file  a  new Form  S-8 within  twenty  (20) days  after  the
Effective Date, to cover the additional shares of Parent Common Stock subject to
the  Parent Options granted in replacement of  the Company Options and shall use
reasonable efforts to cause such shares to be listed on Nasdaq National Market.
 
    Section 3.7.   STOCKHOLDER  APPROVAL.   The Company  shall take  all  action
necessary,  in accordance with applicable law  and its Articles of Incorporation
and By-laws, to convene a special meeting of the holders of Company Common Stock
(the  "Company  Meeting")  as  promptly  as  practicable  for  the  purpose   of
considering  and taking  action upon this  Merger Agreement.  Subject to Section
6.2, the  Board of  Directors of  the  Company will  recommend that  holders  of
Company  Common  Stock vote  in  favor of  the approval  of  the Merger  and the
adoption of this Merger Agreement at the Company Meeting.
 
    Section 3.8.   CLOSING OF THE  COMPANY'S TRANSFER BOOKS.   At the  Effective
Date, the stock transfer books of the Company shall be closed and no transfer of
shares of Company Common Stock shall be
 
                                       5
<PAGE>
made  thereafter. In the event that,  after the Effective Date, Certificates are
presented to the Surviving Corporation, they shall be canceled and exchanged for
Parent Common Stock and/or  cash as provided in  Sections 3.1(a), 3.2, 3.3,  3.4
and 3.5.
 
    Section  3.9.   ASSISTANCE IN  CONSUMMATION OF THE  MERGER.   Parent and the
Company shall provide  all reasonable  assistance to and  shall cooperate  with,
each  other to bring about the consummation of the Merger as soon as practicable
in accordance with  the terms and  conditions of this  Merger Agreement.  Parent
shall cause Merger Sub to perform all of its obligations in connection with this
Merger Agreement.
 
    Section  3.10.   CLOSING.  The  closing of the  transactions contemplated by
this Merger Agreement shall take place at the offices of Ballard Spahr Andrews &
Ingersoll,1735 Market Street, 51st Floor, Philadelphia, Pennsylvania 19103-7599,
at 10:00 A.M. local time on the day which is five business days after the day on
which the last of  the conditions set  forth in Article  VIII (other than  those
requiring  an exchange  of certificates,  or other  documents, or  the taking of
other action, at the Closing) is fulfilled or waived or (ii) at such other  time
and place as Parent and the Company shall agree in writing.
 
                                   ARTICLE IV
                    REPRESENTATIONS AND WARRANTIES OF PARENT
 
    Parent represents and warrants to, and agrees with, the Company as follows:
 
    Section  4.1.  ORGANIZATION AND QUALIFICATION.  Parent is a corporation duly
organized  and  validly  existing  under   the  laws  of  the  Commonwealth   of
Pennsylvania. Parent shall use its best efforts to cause Merger Sub to be, as of
the  Effective Date, a corporation duly  organized, validly existing and in good
standing under  the laws  of the  State  of Vermont.  Parent has  the  requisite
corporate  power  and  authority  to  own,  lease  and  operate  its  assets and
properties and  to  carry on  its  business as  it  is now  being  conducted  or
currently  proposed to be conducted. Parent shall  use its best efforts to cause
Merger Sub to have, as of the Effective Date, the requisite corporate power  and
authority  to own, lease and  operate its assets and  properties and to carry on
its business as it will then be  conducted or then be proposed to be  conducted.
Parent is duly qualified as a foreign corporation to do business, and is in good
standing,  in each jurisdiction  where the character of  its properties owned or
held under  lease  or the  nature  of  its activities  make  such  qualification
necessary,  except where the failure to  be so qualified would not, individually
or in the aggregate, have a Material Adverse Effect on the business, properties,
assets, condition (financial or otherwise), liabilities or operations of  Parent
and  its subsidiaries  taken as  a whole  (a "Parent  Material Adverse Effect").
Parent shall use its best efforts to cause Merger Sub not to have engaged, as of
the Effective Date, in any  business (other than certain organizational  matters
and   matters  relating  to  this  Merger  Agreement)  since  the  date  of  its
incorporation. Complete and correct copies as of the date hereof of the Articles
of Incorporation and  By-laws of Parent  have been provided  to the Company  and
complete  and  correct  copies  as  of  the  date  hereof  of  the  Articles  of
Incorporation and By-laws of Merger Sub shall have been provided to the  Company
prior to the Effective Date.
 
    Section 4.2.  CAPITALIZATION.
 
    (a)  As of the date hereof, the  authorized capital stock of Parent consists
of 10,000,000 shares of  Parent Common Stock and  5,000,000 shares of  Preferred
Stock,  $1.00 par  value ("Parent  Preferred Stock").  As of  December 31, 1995,
there were:  (i) 6,971,283  shares of  Parent Common  Stock validly  issued  and
outstanding  (all of which are fully paid and nonassessable), and (ii) no shares
of Parent Preferred Stock validly issued and outstanding. As of the date hereof,
except for  396,015 shares,  there  are no  options,  warrants, calls  or  other
rights,  agreements or  commitments presently  outstanding obligating  Parent to
issue, deliver or  sell shares  of its capital  stock, or  obligating Parent  to
grant,  extend or enter into any such option, warrant, call or other such right,
agreement or commitment. All  of the shares of  Parent Common Stock issuable  in
accordance  with this Merger  Agreement in exchange for  Company Common Stock or
Company  Options   at   the   Effective   Date  will   be,   when   so   issued,
 
                                       6
<PAGE>
duly  authorized, validly issued,  fully paid and  nonassessable. Parent has not
issued any securities in violation of  any preemptive or similar rights.  Except
as  set forth in  this Section 4.2(a), and  as of the date  hereof, there are no
options, warrants, calls, rights or other securities, agreements or  commitments

for the  periods  then ended  subject,  in the  case  of the  unaudited  interim

    Section 5.6.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed  in
the  Company  SEC Reports  or as  contemplated by  this Merger  Agreement, since
September 30, 1995, there has not been: (i) any transaction, commitment, dispute
or other event or condition (financial  or otherwise) of any character  (whether
or  not in  the ordinary  course of business)  individually or  in the aggregate
having, or likely to have, or which, with or without notice or lapse of time  or
both,  would have, a Company Material Adverse  Effect (other than as a result of
changes in laws or  regulations of general applicability  or changes in  general
economic or market conditions); (ii) any damage, destruction or loss, whether or
not  covered by insurance, which, insofar as  reasonably can be foreseen, in the
future would have a  Company Material Adverse Effect;  (iii) any entry into  any
commitment  or transaction material to the  Company taken as a whole (including,
without limitation, any  borrowing or  sale of  assets) except  in the  ordinary
course  of  business consistent  with past  practice,  or (iv)  any declaration,
setting aside or payment of any dividend or other distribution (whether in cash,
stock or  property) with  respect to  the capital  stock of  the Company.  Since
September  30, 1995, the  Company has not  made any change  in its underwriting,
reserves,  or  claims  adjustment  practices  which,  individually  or  in   the
aggregate,  would have  a Company  Material Adverse  Effect. The  Company is not
aware of any fact  or facts which, with  or without notice or  lapse of time  or
both,  would, individually  or in  the aggregate,  result in  a Company Material
Adverse Effect.
 
    Section  5.7.    LITIGATION.    There  are  no  claims,  suits,  actions  or
proceedings  pending or, to the knowledge  of the Company threatened, against or
affecting the Company,  which, individually  or in  the aggregate  could have  a
Company Material Adverse Effect.
 
    Section 5.8.  LOSS RESERVES; STATUTORY CAPITAL.  The reserves of the Company

adjustment expenses,  incurred  but  not reported  losses  and  loss  adjustment
expenses for incurred but not reported losses (the "Loss Reserves") as set forth
in the audited consolidated financial statements and unaudited interim financial
statements of the Company included in the Company SEC Reports were determined in
good  faith  by the  Company in  accordance  with generally  accepted accounting
principles and were believed by the Company to be reasonable when made. The Loss
Reserves attributable  to the  Company's insurance  business, including  without
limitation reserve and other liability amounts in respect of insurance policies,
whether  direct  or  assumed by  reinsurance,  established or  reflected  in the
respective statutory annual statements  for the three  years ended December  31,
1994,  of  the Company  were determined  in  accordance with  generally accepted
actuarial standards consistently applied and are in compliance, in all  material
respects,  with the requirements of the insurance laws, rules and regulations of
Vermont as well as  those of any  other applicable jurisdictions  (collectively,
"Applicable Insurance Laws"). To the Company's knowledge, the Loss Reserves were
adequate  to cover the total amount of all matured and unmatured liabilities and
obligations of  the Company  under all  their respective  outstanding  insurance
policies,  funding  agreements  and annuity,  guaranteed  interest, reinsurance,
coinsurance and other similar contracts at September 30, 1995. The Company  owns
assets  that qualify  as admitted assets  under Applicable Insurance  Laws in an
amount at least equal to the sum of all such reserves and liability amounts  and
its  minimum statutory  capital and surplus  as required by  the insurance laws,
rules and regulations of Vermont or, to the extent material to the Company,  any
other jurisdiction.
 
    Section  5.9.  REINSURANCE.  None  of the reinsurance treaties and contracts
applicable  to  the  Company   (individually,  a  "Reinsurance  Agreement"   and
collectively,  the "Reinsurance Agreements") will  terminate because of a change
in   control   of   the   Company.   No   other   party   to   any   Reinsurance
 
                                       12
<PAGE>
Agreement has given notice to the Company that it intends to terminate or cancel
any  such Reinsurance Agreement  as a result  of the Merger  or the contemplated
operations of the Company after the Merger is consummated, which termination  or
change could have a Company Material Adverse Effect.
 
    Section 5.10.  COMPLIANCE WITH APPLICABLE LAWS.  The business of the Company
is  not being conducted in violation of  any law, ordinance or regulation of any
legislative, executive,  judicial,  federal,  state  or  local  governmental  or
regulatory  agency or authority  in the United States  or any other jurisdiction
("Governmental Entities"), except where such violation would not have a  Company
Material  Adverse Effect. Other than  routine periodic reviews, no investigation
or review by any Governmental Entity with respect to the Company is pending, nor
has any Governmental Entity indicated to the Company an intention to conduct the
same.
 
    Section 5.11.    LIABILITIES.    The Company  does  not  have  any  material
indebtedness  or liability, absolute, accrued,  contingent or otherwise, whether
due or to become due  (and there is no basis  for any such liability), which  is
not  shown or provided for  in the audited financial  statements included in the
Company's Annual Report on Form 10-KSB for the year ended December 31, 1994 (the
"1994 Financial Statements") other than  liabilities incurred or accrued in  the
ordinary course of business and consistent with past practice since December 31,
1994.
 
    Section 5.12.  WRITTEN INSURANCE POLICIES; REGULATORY FILINGS.
 
    (a)  All policies and contracts of insurance and reinsurance entered into or
issued, as the case may  be, by the Company or  which are being entered into  or
issued  by the  Company as  of the date  hereof, are  in compliance,  and at the
respective dates of issuance were in  compliance, with all applicable laws  and,
to  the  extent required  under applicable  law,  are on  forms approved  by the
appropriate Governmental Entities in the jurisdictions where issued or have been
filed with and  not objected to  by such Governmental  Entity within the  period
provided  for  objection.  Any  premium  rates  with  respect  to  insurance  or
reinsurance policies  or contracts  currently issued  by the  Company which  are
required  to be filed with  or approved by any  Governmental Entity have been so
filed or approved in  accordance with applicable law,  and the premiums  charged
thereon conform thereto. The Company shall not be deemed to have breached all or
any  portion of this Section 5.12  unless such breach or breaches, individually,
or in the aggregate, would result in a Company Material Adverse Effect.
 
    (b) Each Reinsurance Agreement to which the Company is a party is valid  and
binding  on the Company and, to the knowledge  of the Company, in full force and
effect in accordance with its terms, except as enforceability may be limited  by
bankruptcy,  insolvency  or  other  similar laws  affecting  the  enforcement of
creditors rights  generally  and  except  that  the  availability  of  equitable
remedies,  including specific performance,  is subject to  the discretion of the
court before which the enforcement of any proceeding therefor may be brought. To
the knowledge of the Company, it is not in default in any material respect  with
respect  to any  such Reinsurance Agreement,  and no  such Reinsurance Agreement
contains any provision providing that the other party thereto may terminate  the
same  by reason  of the transactions  contemplated by this  Merger Agreement, or
contains any  other  provision  which  would  be  altered  or  otherwise  become
applicable by reason of such transactions.
 
    Section 5.13.  AGENTS.  As of the date hereof, the Company is unaware of any
Agent which is not duly licensed (to the extent that such licenses are required)
in  the jurisdictions in which the Agent  places or sells insurance on behalf of
the Company  and each  Agent is  duly authorized  and appointed  by the  Company
pursuant to Applicable Insurance Laws. To the best knowledge of the Company, all
written contracts or agreements between any Agent, on one hand, and the Company,
on the other hand, are in compliance with Applicable Insurance Laws. The Company
shall  not be deemed  to have breached all  or any portion  of this Section 5.13
unless such breach or breaches, individually  or in the aggregate, would  result
in a Company Material Adverse Effect.
 
    Section 5.14.  TAXES.
 
    (a)  The Company has timely filed all tax returns required to be filed by it
and has paid, or has  set up an adequate reserve  for the payment of, all  taxes
attributable to all periods ending on or before the
 
                                       13
<PAGE>
date  hereof, other  than nonpayments  which would  not have  a Company Material
Adverse Effect. The information shown on such tax returns is true, accurate  and
complete,  and the Company is  not aware of any  basis upon which any assessment
for any additional taxes  could be made, other  than assessments that would  not
have  a Company Material Adverse Effect. All positions taken in such tax returns
that could give rise to a substantial understatement penalty within the  meaning
of  Code Section 6662 have been disclosed therein or the Company has substantial
authority for taking  such positions. No  deficiencies for any  taxes have  been
proposed,  asserted or assessed  against the Company that  have not been finally
settled or paid in full.  Neither the Company nor any  of its present or  former
subsidiaries   (A)  has  been  a  member  of  an  "affiliated  group"  filing  a
consolidated federal income tax return or (B) has any liability for the taxes of
any person  under Treas.  Reg. Section  1.1502-6 (or  any similar  provision  of
state,  local, or foreign  law), as a  transferee or successor,  by contract, or
otherwise. For  the purposes  of this  Merger Agreement,  the term  "tax"  shall
include  all taxes,  however denominated,  including any  interest, penalties or
other additions to tax  that may become payable  in respect thereof, imposed  by
any  federal, territorial, state,  local or foreign government  or any agency or
political subdivision of any such government, which taxes shall include, without
limiting  the  generality  of  the  foregoing,  all  income  or  profits   taxes
(including,  but not limited  to, federal income taxes  and state income taxes),
estimated taxes, payroll and employee withholding taxes, unemployment insurance,
social security taxes,  sales and  use taxes,  ad valorem  taxes, excise  taxes,
capital  stock  or  franchise  taxes, gross  receipts  taxes,  taxes  imposed on
premiums paid,  business  license taxes,  occupation  taxes, real  and  personal
property  taxes,  stamp  taxes, environmental  taxes,  transfer  taxes, workers'
compensation,  Pension   Benefit  Guaranty   Corporation  premiums   and   other
governmental  charges, and other obligations of the  same or of a similar nature
to any of the foregoing, which a corporation may be required to pay, withhold or
collect.
 
    (b) There  are  no  waivers  or extensions  of  any  applicable  statute  of
limitations  for the assessment or collection of  such taxes with respect to the
Companys returns,  which waivers  or  extensions are  currently in  effect.  The
Company   has  not   received  notice   of  any   actions,  suits,  proceedings,
investigations, audits, claims or assessments in connection with any taxes  that
are presently pending.
 
    (c)  The Company has not received a Tax Ruling or entered into a Tax Closing
Agreement with any taxing authority that would have a continuing material effect
after the Effective Date. For purposes of the preceding sentence, the term  "Tax
Ruling" shall mean a written ruling of a taxing authority relating to taxes, and
the  term "Tax Closing Agreement"  shall mean a written  agreement with a taxing
authority relating to taxes.
 
    (d) The Company is not required  to make any adjustment pursuant to  Section
481 of the Code by reason of a change in accounting method or otherwise.
 
    (e)  There are no liens, pledges,  security interests or mortgages for taxes
(other than for taxes not yet due and payable) upon the assets of the Company.
 
    (f) The Company is not a party to any agreement providing for the allocation
or sharing of taxes with any entity.
 
    (g) The  Company  has not  entered  into any  compensatory  agreements  with
respect to the performance of services for which payment thereunder would result
in a nondeductible expense to Company pursuant to Section 280G of the Code.
 
    Section  5.15.   CERTAIN  AGREEMENTS.   The Company  is not  a party  to any
material oral or written: (i) agreement, contract, indenture or other instrument
relating to indebtedness, or  (ii) agreement which, after  giving effect to  the
transactions contemplated by this Merger Agreement, purports to restrict or bind
Parent  or any of its subsidiaries, other than the Surviving Corporation, in any
respect. The Company is not  in default (or in default  with notice or lapse  of
time,  or  both) under  any indenture,  note,  credit agreement,  loan document,
lease, license or  other agreement including,  but not limited  to, any  Company
Benefit  Plan (as defined in Section 5.21), whether or not such default has been
waived, which  default has  or would  have, if  not waived,  a Company  Material
Adverse Effect.

    Section 5.16.  PREMIUM BALANCES RECEIVABLE.  The premium balances receivable
of  the  Company as  reflected  in its  September  30, 1995  Quarterly Financial
Statements, to  the extent  uncollected  on the  date  hereof, and  the  premium
balances receivable reflected on the books of the Company as of the date hereof,

complete list  of  the  securities  and other  investments  in  such  investment
portfolio,  as of December  31, 1995, is  listed in Section  5.17 of the Company

insurance  laws and regulations  of each of  the states to  which the Company is
subject relating thereto.
 
    Section 5.18.  INTELLECTUAL PROPERTY.  All Intellectual Property, as defined
below, listed is  owned by  the Company  free and  clear of  all liens,  claims,
licenses or other encumbrances and is not known by the Company to be the subject
of  any challenge. There  are no unresolved  claims made and  there has not been
communicated to the  Company the threat  of any  claim that the  holder of  such
Intellectual  Property is in violation or infringement of any trademark, service
mark, patent, trade name, copyright,  trade secret or copyright registration  of
any  other person.  The Company  is the owner  of the  patents, patent licenses,
trade  names,  trademarks,  service  marks,  trade  secrets,  pending  trademark
applications,  pending  copyright applications,  copyrights, know-how  and other
proprietary rights necessary for the conduct  of its business as now  conducted,

Merger Agreement, "Intellectual Property" shall mean all letters patent,  patent
applications,  trademarks,  service  marks,  trade  names,  copyrights,  pending
trademark applications, pending copyright  applications and licenses and  rights
with respect to the foregoing that the Company owns or possesses.
 
    Section   5.19.    LICENSES.    The   Company  has  obtained  all  licenses,
certificates of authority, permits, authorizations, orders and approvals of, and
have made  all  registrations or  filings  with, all  Governmental  Entities  as
required  in connection with the conduct of  the businesses of the Company other
than  licenses,  certificates,   permits,  authorizations,  orders,   approvals,
registrations  or filings which if not obtained or made would not have a Company
Material Adverse  Effect (collectively,  the "Licenses").  Section 5.19  of  the
Company  Disclosure Schedule sets forth a true and complete list of the Companys
Licenses (including the jurisdictions in which the Company possesses Licenses or
other approvals to conduct its insurance businesses) together with a description
of the nature thereof. The Company is not transacting any insurance business  in
any  jurisdiction in which  it is not  authorized or permitted  to transact such
business. All Licenses are valid and in  full force and effect. No such  License
is  the  subject  of  a  proceeding  for  suspension  or  revocation  or similar
proceedings, and to the Company's knowledge no such proceeding is threatened.

arrangements  relating  to  former  employees,  maintained,  contributed  to, or
sponsored by the Company (together, the "Company Benefit Plans"). Except to  the
extent  that  a  breach  of  the following  representations  would  not,  in the

Merger does not trigger any payment obligations (contingent or otherwise) by, or
increase  any liabilities of, the Company under any Company Benefit Plan; (b) no
default exists with respect to the obligations of the Company under any  Company
Benefit  Plan; (c)  there have  been no  disputes or  grievances subject  to any

litigation under any Company Benefit Plan, which have not been finally resolved,
settled  or otherwise disposed  of, nor is  there any default,  or any condition
which, with notice or lapse  of time or both,  would constitute such a  default,
under  any Company Benefit Plan, by the  Company or any other party thereto, and
(d)  there  have  been  no  strikes,  lockouts  or  work  stoppages,  slowdowns,
jurisdictional  disputes  or organizing  activity  occurring or  threatened with
respect to the business or operations of the Company. All Company Benefit  Plans

provisions of ERISA, the Code and other applicable law.

to meet the requirements of  Section 401(a) of the  Code has been determined  by
the  Internal  Revenue Service  to  be "qualified"  within  the meaning  of such
section of  the Code,  and the  Company knows  of no  fact which  would have  an
adverse  effect on the  qualified status of  such plans. There  are not now, nor
have there  been, any  non-exempt  "prohibited transactions,"  as such  term  is
defined  in Section  4975 of  the Code  or Section  406 of  ERISA, involving the
Company Benefit Plans which could subject  the Company, Parent or the  Surviving
Corporation  to any liability  under Title I of  ERISA or to  any penalty or tax
imposed under Section 502(i) of ERISA or  Section 4975 of the Code. The  Company
has  never maintained, sponsored, or contributed to any plan subject to Title IV
of ERISA, and the Company, has not otherwise incurred any liability under  Title

fact,  other  than circumstances,  matters or  events attributable,  directly or
indirectly, to Parent which, with or without the passage of time, would  prevent

currently being conducted,  except as otherwise  contemplated hereby and  except
with  respect to  regulatory notices,  filings and  applications that  Parent is
required to  make  in  connection  with the  consummation  of  the  transactions
contemplated hereby and with such other exceptions as would not, individually or
in the aggregate, have a Company Material Adverse Effect.

would not  jeopardize the  characterization of  the Merger  as a  reorganization
within  the meaning of Section 368(a)(1)(A) and 368(a)(2)(E) of the Code. Parent
will provide the Company  with certain factualy  representations of Parent,  and
Parent will use its best efforts to cause Merger Sub to provide the Company with
certain  factual  representations of  Merger  Sub, reasonably  requested  by the
Company as necessary to  confirm that Parent  and Merger Sub  will not take  any
action  on  or after  the  Effective Date  that  would jeopardize  the  tax free
 
                                       20

Statement and any  amendments or  supplements thereto, and  at the  time of  the
Company Meeting to be held in connection with the Merger, or, in the case of the
Registration  Statement, at the  time it becomes effective  and at the Effective
Date, contain any  untrue statement  of a  material fact  or omit  to state  any
material  fact required to be  stated therein or necessary  in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. Parent agrees that the Registration Statement will comply as to form
in all material respects with the provisions of the Securities Act and the rules
and regulations  promulgated  thereunder.  The Company  agrees  that  the  Proxy
Statement will comply as to form in all material respects with the provisions of
the Exchange Act and the rules and regulations thereunder.
 
    Section  7.8.  INDEMNIFICATION.   From and after  the Effective Date, Parent

Parties")   against  all  losses,  expenses,  claims,  damages  or  liabilities,
including those  arising out  of the  transactions contemplated  by this  Merger
Agreement  (excluding criminal  liabilities), based in  whole or in  part on any
action or omission, except any action  or omission which was grossly  negligent,
reckless,  wanton  or  intentional, occurring  prior  to the  Effective  Date in

or director of the Company ("Claims"). In  the event of any such loss,  expense,
claim, damage or liability (whether arising before or after the Effective Date):
(i) Parent shall pay the reasonable fees and expenses of the Indemnified Party's
counsel,provided such counsel is reasonably acceptable to Parent, promptly after
statements  therefor are received, (ii) Parent  and the Indemnified Parties will
cooperate in  the  defense of  any  such  matter, and  (iii)  any  determination
required  to be made with respect to whether an Indemnified Party is entitled to
indemnification shall be  made to the  fullest extent permitted  under the  VBCA
consistent  with the standards set forth in  the first sentence of this Section,
by independent legal  counsel acceptable  to Parent and  the Indemnified  Party;
provided,  however, that Parent shall not  be liable for any settlement effected
without its written consent (which consent shall not be unreasonably  withheld).
Parent  agrees  that all  rights  to indemnification  existing  in favor  of the
directors, officers or  employees of the  Company as provided  in the  Company's
Articles  of Incorporation or Bylaws,  as in effect as  of the date hereof, with

whole,  substantially equivalent to or better  than the benefits offered to such
persons by the Company, as the case  may be, immediately prior to the  Effective
Date; provided, however, that neither Parent nor the Surviving Corporation shall
be  required to adopt or maintain any plan or arrangement providing for the sale
of the Parent Common Stock or Company Common Stock.

    AMENDMENT  NO.  1,  dated as  of  May  10, 1996  (the  "Amendment"),  to the
Agreement and Plan  of Merger  (the "Agreement"), dated  as of  March 15,  1996,
between  Penn  Treaty American  Corporation ("Parent")  and Health  Insurance of
Vermont, Inc. (the "Company").
 
                              W I T N E S S E T H:
 
    WHEREAS, the Agreement  provides, among other  things, for the  merger of  a
wholly-owned  subsidiary of Parent to be formed as soon as practicable following
the execution of the Agreement ("Merger Sub") with and into the Company upon the
terms and subject to the conditions  set forth in the Agreement (the  "Merger");
and
 
    WHEREAS,  Parent and the Company have mutually agreed to amend the Agreement
to, among other things, modify the acceptable range of the average bid price per
share of Parent  Common Stock, which  is used  in the computation  of the  Final
Price (as defined in the Agreement), from no less than $16.00 or no greater than
$18.00  to no less than $15.00 or no  greater than $20.00 and to extend the date
by which the Merger must be consummated from July 31, 1996 to August 31, 1996.
 
    NOW,  THEREFORE,  in  consideration  of  the  premises  and  the  agreements
hereinafter set forth, and intending to be legally bound, Parent and the Company
agree as follows:
 
         1.  Subsection  3.1(b)(iii)  of  the Agreement  is  hereby  amended and
    restated in its entirety as follows:
 
         "(iii) The "Final Price"  shall mean the average  closing bid price  of
       Parent  Common  Stock on  the Nasdaq  National  Market during  the period
       comprised of the  twenty consecutive trading  days immediately  preceding
       the  fifth business  day immediately  preceding the  Effective Date (such
       period is hereinafter referred to  as the "Measurement Period"), as  such
       closing   bid  prices  are  published  by  the  National  Association  of
       Securities Dealers Automated Quotation  Service; provided, however,  that
       if  the  average  closing price  of  Parent Common  Stock,  determined in
       accordance with the first clause of this sentence, during the Measurement
       Period is more than  $.20 per share higher  than the average closing  bid
       price  of Parent  Common Stock during  the Measurement  Period, the Final
       Price shall equal  the average  closing price  per share  minus $.20  per
       share  but this adjustment shall not cause  the Final Price to be reduced
       to a price per share  less than the average  closing bid price of  Parent
       Common  Stock during the Measurement Period. If the Final Price of Parent
       Common Stock,  determined in  accordance with  the immediately  preceding
       sentence,  is  less  than  $15.00 or  greater  than  $20.00,  this Merger
       Agreement shall terminate; provided, however, that the parties hereto may
       waive this termination provision in writing."
 
         2. Subsection 9.1(b) of the Agreement is hereby amended and restated in
    its entirety as follows:
 
           "(b) By either  Parent or the  Company if the  Merger shall not  have
       been  consummated on or before August  31, 1996 (provided the terminating
       party is  not  otherwise  in  material  breach  of  its  representations,
       warranties  or obligations under this Merger Agreement or responsible for
       the failure of the Merger to occur on or before such date)."
 
         3. Except as provided herein, the Agreement shall remain unchanged  and
    in full force and effect.
 
         4.  This Amendment may be executed in one or more counterparts, each of
    which shall  be  deemed  an  original,  but  all  of  which  together  shall
    constitute one and the same instrument.

    IN  WITNESS WHEREOF, the parties hereto have duly executed this Amendment as
of the day and year first above written.

Board of Directors
Health Insurance of Vermont, Inc.

Colchester, VT 05446-0630
 
Dear Sirs:
 
    We understand that Penn Treaty American Corporation ("PTAC") has proposed to
acquire  Health Insurance of Vermont, Inc. ("HIVT" or the "Company") by means of
a statutory  merger  of  a wholly-owned  subsidiary  of  PTAC to  be  formed  in
connection  with this transaction with and into HIVT, resulting in HIVT becoming
a wholly-owned subsidiary  of PTAC  (the "Proposed  Acquisition"). The  purchase
price  of the transaction is  $20 per share based  on 550,095 shares outstanding
(assuming exercise of all outstanding options for HIVT common stock)  consisting
of:  (a) Two Million Two  Hundred Thousand Three Hundred  Eighty Dollars in cash
consideration ($2,200,380); and  (b) Eight  Million Eight  Hundred One  Thousand
Five  Hundred  Twenty Dollars  in common  stock consideration  ($8,801,520). The
terms and conditions of the Proposed Acquisition are set forth in more detail in
the Agreement and Plan of Merger dated as of March 15, 1996 (the "Agreement").
 
    Advest, Inc. is  an investment bank  regularly engaged in  the valuation  of
businesses  and their securities in connection with mergers and acquisitions. We
have acted as  financial advisor to  the Board  of Directors of  the Company  in
connection with the transaction contemplated by the Agreement.
 
    We  have been requested by the Company to render our opinion with respect to
the fairness, from a financial point  of view, to the Company's stockholders  of
the consideration to be offered in the Proposed Acquisition.
 
    In  arriving at our opinion, we reviewed and analyzed: (1) documents used in
connection with  the  Proposed Acquisition  including  the Agreement  and  other
publicly  available information  concerning the Company  which we  believe to be
relevant to our inquiry, (2) financial and operating information with respect to
the business operations and prospects  of the Company including annual  reports,
10-KSB  filings, 10-QSB filings, and  annual and quarterly statutory statements,
(3) a trading history of  the Company's common shares  from 1990 to the  present
and  a comparison  of that  trading history  with those  of companies  we deemed
comparable, and  (4)  a  comparison  of the  financial  terms  of  the  Proposed
Acquisition  with the terms of certain other recent transactions which we deemed
relevant. In  addition, we  have  had discussions  with  the management  of  the
Company  concerning its business  and operations, assets,  present condition and
future prospects and undertook such  other studies, analyses and  investigations
as we deemed appropriate.
 
    Since  PTAC is a publicly traded corporation and is issuing shares of common
stock to the stockholders of HIVT as  a portion of the merger consideration,  it
was  also necessary to review certain relevant information with respect to PTAC.
Accordingly, we reviewed and analyzed:  (1) financial and operating  information
with  respect to the business operations  and prospects of PTAC including annual
reports,  10-K  filings,  10-Q  filings  and  annual  and  quarterly   statutory
statements,  (2) a trading history  of PTAC common shares  from 1990 to present,
(3) as  analysis  of  the financial  performance  of  PTAC as  compared  to  its
comparable  peer group,  and (4)  an analysis  of the  financial effects  of the
Proposed Acquisition  on the  Balance Sheet  and Income  Statement of  PTAC.  In
addition,  we have  had discussions with  the management of  PTAC concerning its
business and  operations, assets,  present condition  and future  prospects  and
undertook   such  other  studies,  analyses  and  investigations  as  we  deemed
appropriate.

    We have relied upon the accuracy and completeness of the financial and other
information  used  by  us  in  arriving  at  our  opinion  without   independent
verification.  In  arriving at  our opinion,  we have  conducted only  a limited
physical inspection of  the properties and  facilities of HIVT  and of PTAC.  We
have  not made nor obtained any evaluations  or appraisals of the assets of HIVT
or PTAC. Our opinion is necessarily based upon conditions as they exist and  can
be  evaluated as  of the  date of  this letter.  Based upon  and subject  to the
foregoing, we are  of the  opinion that,  from a  financial point  of view,  the
consideration  to  be  offered  in  the  Proposed  Acquisition  is  fair  to the
stockholders of HIVT.

                                   May 14, 1996



Penn Treaty American Corporation
3440 Lehigh Street
Allentown, Pennsylvania  18103

Gentlemen:

          We have acted as your counsel in connection with the
proposed issuance of shares of common stock in connection with
the proposed merger (the "Merger") pursuant to which a wholly
owned subsidiary of Penn Treaty American Corporation (the
"Company"), will be merged with and into Health Insurance of
Vermont, Inc. ("HIVT") and pursuant to which HIVT will become a
wholly owned subsidiary of the Company, as more fully described in
the Registration Statement on Form S-4 filed with the Securities and
Exchange Commission under the Securities Act of 1933 on May 14, 1996.

          In this connection, we have examined and relied upon
such corporate records and other documents, instruments and
certificates and have made such other investigation as we deemed
appropriate as the basis for the opinion set forth below.

          Based upon the foregoing, we are of the opinion that
the shares of common stock to be issued by you have been duly
authorized and, when duly executed, delivered and paid for in
accordance with the terms of the Merger, and upon satisfaction of
all applicable conditions, will be duly and validly issued, fully
paid and nonassessable.

          We hereby consent to the filing of this opinion as an
exhibit to the Registration Statement and to the reference to
this firm under the caption "Legal Matters" in the Prospectus
forming a part thereof.

                                   Very truly yours,



                                   Ballard Spahr Andrews & Ingersoll

                                        __________________, 1996



Health Insurance of Vermont, Inc.
One Roosevelt Highway 
Colchester, VT  05446

Ladies and Gentlemen:

     This letter is in response to your request for our opinion with respect to
certain federal income tax consequences of the proposed merger (the "Merger") of
"Merger Sub", a Vermont corporation to be incorporated as a wholly-owned
subsidiary of Penn Treaty American Corporation, a Pennsylvania corporation
("Penn Treaty"), with and into Health Insurance of Vermont, Inc. ("HIVT"), a
Vermont corporation, pursuant to the Agreement and Plan of Merger dated as of
March 15, 1996 (the "Merger Agreement").  The facts concerning the Merger are
described in the Proxy Statement/Prospectus of HIVT and Penn Treaty filed with
the Securities and Exchange Commission on ______________, 1996.  Unless
otherwise specified, capitalized terms used herein are as defined in the Proxy
Statement/Prospectus.

     In connection with the proposed Merger, we understand the following:

     1.   Merger Sub will be duly incorporated in the State of Vermont. 

     2.   Pursuant to the laws of the State of Vermont, Merger Sub will merge
          with and into HIVT, which will be the surviving corporation.

     3.   At the Effective Date, each outstanding share of HIVT Common Stock
          will be converted into a right to receive $4 in cash (hereafter the
          "Cash Boot") and shares of Penn Treaty Common Stock as determined in
          accordance with the Exchange Rate.

     4.   At the Effective Date, each holder of HIVT Common Stock who otherwise
          would have been entitled to a fractional share of Penn Treaty Common
          Stock will receive cash in lieu thereof. 

     5.   As soon as practicable on or after the Effective Date, the Exchange
          Agent will distribute Penn Treaty Common Stock, the Cash Boot and cash
          in lieu of fractional shares to holders of HIVT Common Stock.

     6.   Penn Treaty will cause HIVT to continue to conduct the historic
          business of HIVT or use a significant portion of HIVT's historic
          business assets in a business within the meaning of Treasury
          Regulation Section 1.368-1(d).

     In connection herewith, we have examined the Merger Agreement, the
Registration Statement on Form S-4 filed by Penn Treaty with the Securities and
Exchange Commission (which contains a Proxy Statement/Prospectus of HIVT) and
such other information as we have deemed relevant.  As to questions of fact
material to the opinions herein, we have relied upon representations of HIVT and
Penn Treaty set forth in certificates executed by their respective officers, as
well Penn Treaty's covenant in the Merger Agreement that it will not take any
action, nor will it cause HIVT to take any action, following the Effective Date
of the merger, that would jeopardize the characterization of the Merger as a
reorganization within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of
the Code.  Moreover, we have assumed that the Merger will be completed in the
manner set forth in the Proxy Statement/Prospectus, and that the representations
and covenants made by the parties to the Merger are accurate and complete and
that such representations and covenants will continue to be accurate and
complete as of the Effective Date of the Merger.  On the basis of the foregoing
and subject to the conditions, qualifications and limitations set forth herein,
we are of the opinion that for federal income tax purposes:

     1.   The Merger will qualify as a tax-free reorganization within the
          meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal
          Revenue Code 1986, as amended (the "Code"), and HIVT and Penn Treaty
          will each be a party to the reorganization.

     2.   No gain or loss will be recognized by HIVT as a result of the Merger.

     3.   Gain, if any, will be recognized by a shareholder of HIVT upon the
          exchange of HIVT Common Stock for Penn Treaty Common Stock and Cash
          Boot to the extent of the lesser of (i) the Cash Boot or (ii) the
          excess of the fair market value of the Penn Treaty Common Stock, the
          Cash Boot and all other property received by an HIVT shareholder over
          that shareholder's basis in his HIVT stock.  Otherwise, no other gain
          or loss will be recognized by a shareholder of HIVT upon the exchange
          of shares of HIVT Common Stock for Penn Treaty Common Stock, except
          that gain or loss will be recognized by a shareholder of HIVT upon the
          receipt of cash in lieu of a fractional share interest in Penn Treaty
          Common Stock.

     4.   The adjusted tax basis of the Penn Treaty Common Stock received by a
          shareholder of HIVT pursuant to the Merger (including fractional share
          interests deemed received) will be equal to the adjusted tax basis of
          the shares of HIVT Common Stock surrendered in exchange therefor,
          decreased by the amount of Cash Boot received in the exchange and any
          loss recognized on the exchange, and

                                                            Page 3              


          increased by the amount of gain, if any, recognized on the exchange by
          the HIVT shareholder.

     5.   The holding period of the Penn Treaty Common Stock received by a
          shareholder of HIVT as a result of the Merger (including fractional
          share interests deemed received) will include the holding period of
          the shares of HIVT Common Stock surrendered in exchange therefor,
          provided that such HIVT Common Stock is held as a capital asset by the
          HIVT shareholder at the consummation of the Merger.

     6.   Any cash payment received by a holder of HIVT Common Stock in lieu of
          a fractional share of Penn Treaty Common Stock will be treated as if
          such fractional share of Penn Treaty Common Stock had been issued in
          the Merger and then redeemed by Penn Treaty.

     The opinions expressed above are based upon our opinion that the continuity
of interest requirement of Treasury Regulations Section 1.368-1(b) will be
satisfied.  The continuity of interest requirement will be satisfied if HIVT's
shareholders receive in the Merger and retain Penn Treaty Common Stock equal in
value, as of the Effective Date, to at least 50% of the value of all of the
formerly outstanding shares of HIVT Common Stock as of that date.  The Internal
Revenue Service (the "Service") established in Revenue Procedure 77-37, as
modified to the date hereof, ruling guidelines with respect to satisfying the
continuity of interest requirement.  In order to satisfy those guidelines in
connection with a ruling request, a publicly traded company must represent to
the Service that there is no plan or intention by the company's shareholders who
own 5 percent or more of the company's stock, and to the best of the knowledge
of the management of the company, there is no plan or intention on the part of
the remaining shareholders of the company, to sell, exchange, or otherwise
dispose of a number of shares of the acquiring parent's stock received in the
transaction that would reduce the company's shareholders' ownership of the
acquiring parent's stock to a number of shares having a value, as of the date of
the transaction, of less than fifty percent of the value of all of the formerly
outstanding stock of the company as of the same date.  The Service has adopted a
no-ruling policy with respect to transactions such as the Merger, stating that
it believes that the tax consequences of such transactions are adequately
addressed in the tax law, including but not limited to the Revenue Procedure.
Management of HIVT has represented to us, based upon HIVT's absence of knowledge
as to any plan or intention on the part of the shareholders, that there is no
plan or intention by shareholders of HIVT who own 5 percent or more of its stock
and, to the best of management's knowledge, there is no plan or intention on the
part of the remaining HIVT shareholders, to sell, exchange or otherwise dispose
of such number of shares of Penn Treaty Common Stock received in the Merger that
would result in a failure to satisfy the continuity of interest requirement as
prescribed in the Treasury Regulations and the Service ruling guidelines as set
forth in Revenue Procedure 77-37, as modified to the date hereof.  Our opinion
that the continuity of interest requirement will be satisfied is based upon
management's representation to us, the ruling guidelines as set forth in

Revenue Procedure 77-37 and on the expressed reasoning of the Service for its
adoption of the no-ruling policy.

     This opinion does not relate to or purport to cover any matters other than
the ones expressly stated herein.  The opinion expressed herein is limited to
the consequences of the Merger under current federal income tax law (including
the Code, the Treasury Regulations promulgated thereunder, and administrative
and judicial interpretations thereof) as of the date of this opinion letter.  No
opinion is expressed with respect to state, local, foreign or other tax laws.
Moreover, this opinion does not apply to (i) holders of HIVT Common Stock
subject to special tax treatment under the federal income tax laws or (ii)
holders of HIVT Common Stock who acquired their stock pursuant to the exercise
of an employee stock option or otherwise as compensation or in exchange for HIVT
options.  We assume no obligation to revise or supplement this opinion should
the present federal income tax laws be changed by any legislation, judicial
decisions, or otherwise.

     This opinion is based upon existing law, regulations, administrative
rulings and judicial opinions.  No assurance can be given that changes in law or
regulation or forthcoming opinions or decisions may not modify the conclusions
expressed in this opinion.  Further, no assurance can be given that the service
will not apply stricter standards than set forth in its advance ruling
guidelines or that it will not challenge the conclusions stated in this opinion.

     We hereby consent to the reference to us under "Certain Federal Income Tax
Consequences" in the Proxy Statement/Prospectus forming a part of the
Registration Statement and to the filing of a copy of this opinion as an exhibit
to the Registration Statement.

                                        Very truly yours,
