    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.

    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

                                    for performance of any of  the obligations of the  other
                                    party  or  may waive  conditions  with respect  to those

                                    Merger.  See  "The  Merger   --  Rights  of   Dissenting
                                    Stockholders."
Certain Regulatory Matters........  Consummation   of  the  Merger  is  subject  to  certain

                                    given,  Penn Treaty and HIVT believe that the Merger can
                                    be effected  in compliance  with all  federal and  state
                                    regulations.  See  "The  Merger  --  Certain  Regulatory

Certain Federal Income
 Tax Consequences.................  The  Merger  is  intended  to  qualify  as  a   tax-free
                                    reorganization  for federal income  tax purposes so that
                                    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
                                    Directors with respect to the Merger, HIVT  stockholders
                                    should  be  aware that  members of  the HIVT  Board have

                                    employee.  See  "The  Merger  --  Interests  of  Certain
                                    Persons  in  the  Merger"  for  a  description  of  such
                                    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."

LOOKING. ALTHOUGH PENN TREATY AND HIVT  BELIEVE THEIR EXPECTATIONS ARE BASED  ON
REASONABLE ASSUMPTIONS WITHIN THE BOUNDS OF THEIR BUSINESS AND OPERATIONS, THERE

              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 SPECIAL 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,
6,982,845 shares of Common Stock, including the shares issued upon completion of
the  Merger,  will  generally  be  freely  transferable  by  persons  other than
affiliates of Penn Treaty without restriction or further registration under  the
Securities Act. The remaining 594,007 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.  Upon  completion  of the  merger,  HIVT  will be  subject  to certain
additional restrictions with respect to "extraordinary dividends" it may pay  to
Penn  Treaty. See "Comparison of Rights of  HIVT and Penn Treaty Shareholders --
Dividends and Distributions."
    
 
    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.

SPECIAL MEETING
    
 
   
    The  Special Meeting will  be held at  the Hampton Inn  & Conference Center,
Colchester, Vermont on July 11, 1996, at  12:00 p.m., and at any adjournment  or
postponement thereof.
    
 
MATTERS TO BE CONSIDERED -- THE MERGER
 
   
    At  the Special 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  Special 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 Special  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 Special Meeting.

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)

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

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

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.

    INDEPENDENT  PUBLIC ACCOUNTANTS.   Coopers  & Lybrand  L.L.P. will  serve as
HIVT's independent public accountants for 1996  and has served in that  capacity
for  a number of years. The report of Coopers & Lybrand L.L.P. respecting HIVT's

    OTHER  PROPOSED ACTIONS.  Pursuant to the  Bylaws, it is proposed to elect a

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,
if the Merger is approved.
 
    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.
    
 
QUORUM
 
   
    The  presence, in person  or by proxy, of  the holders of  a majority of the
outstanding shares of HIVT Common Stock  at the Special Meeting is necessary  to
constitute a quorum at the HIVT Special Meeting.
    
 
VOTES REQUIRED
 
   
    The  affirmative vote  of the  holders of  two-thirds of  the votes  cast by
Stockholders present, either in  person or by proxy,  at the Special Meeting  is
required to approve the Merger Agreement.
    
 
   
    The  affirmative vote of a majority of the stockholders present in person or
by proxy at the Special  Meeting is necessary to  ratify and approve the  action
taken by HIVT's Board of Directors with respect to the Reimbursement Proposal.
    
 
   
    The affirmative vote of a plurality of the stockholders present in person or
by proxy at the Special Meeting is necessary to elect members of HIVT's Board of
Directors and its Secretary.
    
 
RECORD DATE; STOCK ENTITLED TO VOTE
 
   
    The  HIVT Board  of Directors has  established May  30, 1996 as  the date to
determine those record holders of Common Stock entitled to notice of and to vote
at the Special Meeting. On that date,  there were 549,095 shares of HIVT  Common
Stock  outstanding, with  each share  entitled to one  vote with  respect to the
Merger Agreement.
    
 
VOTING OF PROXIES
 
   
    Shares represented by all properly executed proxies received in time for the
Special Meeting will be  voted at such  meeting in the  manner specified by  the
holders  thereof. Proxies that do not  contain voting instructions will be voted
FOR approval  of  the  Merger  Agreement, the  Reimbursement  Proposal  and  the
nominees  of the Board of Directors at the  Meeting. It is not expected that any
matter other than those  referred to herein will  be brought before the  Special
Meeting. If, however, other matters are properly presented, the persons named as
proxies  will  vote  in accordance  with  their  judgment with  respect  to such
matters.
    
 
    If a holder of HIVT Common Stock does not return a signed proxy card, his or
her shares will not be voted.
 
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 Special 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)
attending  the Special Meeting and voting in person. Attendance by a stockholder
at the Special Meeting will not itself revoke his or her proxy.
    
 
                                       23
<PAGE>
SOLICITATION OF PROXIES
 
   
    Solicitation of proxies for use at the Special 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.

    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 30,  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
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.
 
    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
 
                                       25
<PAGE>
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.
 
    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. During June 1995, HIVT engaged
Advest to assist it in  considering possible strategic alliances,  combinations,
and trasactions with various industry participants and other interested parties.
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;
 
     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.
 
                                       27

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 SPECIAL 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 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
 
                                       28
<PAGE>
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 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.
 
                                       29
<PAGE>
    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 Company  Merger Statute"), Merger  Sub will be  merged
with  and  into HIVT  at  the Effective  Time.  In connection  with  the Merger,
Articles of Merger will be filed as  soon as practicable after the Closing  with
the  Vermont  Department  of  Banking,  Insurance,  and  Securities  which, upon
approval, will forward the Articles of Merger to the Vermont Secretary of State.
The Merger will  become effective  immediately when the  Certificate of  Merger,
based  on the  Articles of Merger,  is issued by  the Secretary of  State of the
State of Vermont.
    
 
   
    The Closing shall take place at 10:00  a.m. on 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 holders 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.
 
    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.
 
                                       30
<PAGE>
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.
 
   
    JOHN W. MAHONEY MEMBERSHIP ON PENN TREATY  BOARD.  On May 24, 1996, John  W.
Mahoney  was elected to the Penn Treaty Board of Directors. On June 5, 1996, Mr.
Mahoney resigned from the Penn Treaty Board of Directors. There were no meetings
of the Penn Treaty  Board of Directors  during the period from  May 24, 1996  to
June 5, 1996 and Mr. Mahoney took no actions as a director of Penn Treaty.
    
 
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
    
 
                                       31
<PAGE>
   
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 Special
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.
    
 
                                       32

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 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  Company 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 a 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
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
 
                                       34
<PAGE>
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.
 
    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
 
                                       35
<PAGE>
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.
 
   
    Under Vermont insurance law,  insurance companies are  not permitted to  pay
"extraordinary dividends" to an affiliate without first providing 30 days' prior
written  notice to the  Vermont Department of  Banking, Insurance and Securities
which may  disapprove of  the dividend.  For purposes  of this  provision,  Penn
Treaty  would qualify as an affiliate of  HIVT upon completion of the merger. An
extrordinary dividend is defined as  a dividend in excess  of the lesser of  (i)
the  net earnings  of the  company during the  preceding calendar  year plus net
income not paid out as dividends during the prior 2 calendar years, and (ii) 10%
of the  capital  surplus  of  the company,  determined  as  of  the  immediately
preceding December 31.
    
 
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  Company 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
 
                                       36
<PAGE>
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 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.
 
                                       37
<PAGE>
    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.
 
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 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.

    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
    prohibit  the Board of Directors of HIVT from: (i) furnishing information to
    or entering into discussions or negotiations with, any person or entity that
    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

    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

    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

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 and the three months ended March 31, 1996. The pro forma balance  sheet
assumes the Merger occurred at March 31, 1996. 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 three
months ended March 31, 1996 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
three months ended March 31, 1996 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.

(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
    unrealized gain (net of $1,512,000  in deferred income taxes) on  investment
    securities  classified  as  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 unrealized gains of
    $6,146,000 in  the Company's  investment portfolio.  As of  March 31,  1996,
    shareholders'  equity was increased by $1,374,000 due to unrealized gains of
    $2,082,000 in  the  Company's  investment portfolio.  These  increases  were
    caused primarily by decreases in interest rates.

(2)  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  $288,051 to  reflect the net
     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
     $236,889,  net  of  deferred  income taxes,  due  to  unrealized  losses of
     $524,940 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.  As of  March 31,  1996, shareholders'  equity was  increased by
     $128,828, net of deferred income taxes due to unrealized gains of  $155,214
     in   the  Company's  investment  portfolio.  These  increases  were  caused
     primarily by decreases in interest rates.

                          AGREEMENT AND PLAN OF MERGER
 
    This Agreement and Plan of Merger (the "Merger Agreement") is by and between
PENN  TREATY  AMERICAN CORPORATION,  a  Pennsylvania corporation  ("Parent") and
HEALTH INSURANCE OF VERMONT, INC., a Vermont corporation (the "Company").
 
                                   BACKGROUND
 
    A.  The  Boards of Directors  of Parent  and the Company  have approved  the
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.
 
                                   ARTICLE I
                                   THE MERGER
 
    Section  1.1.   THE MERGER.   Upon the  terms and subject  to the conditions
hereof, on the Effective Date (as defined  in Section 1.2), Merger Sub shall  be
merged  with and into the Company and the separate existence of Merger Sub shall
thereupon cease,  and the  Company shall  be the  surviving corporation  in  the
Merger,  (the  "Surviving Corporation")  and the  name of  the Company  shall be
changed to "American Network Life Insurance Company".
 
    Section 1.2.    EFFECTIVE DATE  OF  THE MERGER.    The Merger  shall  become
effective  when a properly executed Certificate of Merger is duly filed with the
Secretary of  State  of  the  State  of Vermont,  which  filing  shall  be  made
concurrently  with the closing  of the transactions  contemplated by this Merger
Agreement in accordance with  Section 3.10. When used  in this Merger  Agreement
the  term  the "Effective  Date"  shall mean  the date  and  time at  which such
Certificate of Merger is so filed or  at such time thereafter as is provided  in
such Certificate of Merger.
 
    Section 1.3.  CONVERSION OF SHARES.  As of the Effective Date, each share of
Company  Common  Stock (as  defined herein)  shall be  converted into  shares of
Parent  Common  Stock  (as  defined  herein)  plus  $4.00  of  Per  Share   Cash
Consideration (as defined herein) pursuant to the terms set forth in Article III
of this Agreement.
 
    Section  1.4.   TAX-FREE REORGANIZATION.   The parties intend  to adopt this
Merger Agreement as  a tax-free  plan of  reorganization and  to consummate  the
Merger   in  accordance  with  the   provisions  of  Sections  368(a)(1)(A)  and
368(a)(2)(E) of the Code.
 
    Section 1.5.  DISSENTERS'  RIGHTS.  Notwithstanding  any other provision  of
this  Agreement  to  the  contrary,  shares of  Company  Common  Stock  that are
outstanding immediately  prior to  the  Effective Date  and  which are  held  by
shareholders  who  shall have  not voted  in  favor of  the Merger  or consented
thereto in  writing and  who shall  have demanded  properly appraisal  for  such
shares  in accordance with the Vermont Business Corporation Act (the "VBCA") and
who shall not have withdrawn such demand
 
<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
their  rights to appraisal of such shares shall be deemed to have been converted
into and to have become exchangeable, as of the Effective Date, for the right to
receive, without interest,  the Merger  Consideration, in the  manner set  forth
elsewhere herein.
 
                                   ARTICLE II

except that the Articles of Incorporation of the Surviving Corporation shall  be
amended,  in  accordance with  the  terms thereof  and  of the  Vermont Business
Corporation Act ("VBCA"), to provide that the name of the Surviving  Corporation
shall be "American Network Life Insurance Company".
 
    Section  2.2.  BY-LAWS.  The By-laws  of Merger Sub as in effect immediately

                                  ARTICLE III
                              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.

distributions  that are declared or made on  Parent Common Stock will be paid to
persons entitled  to  receive  certificates  representing  Parent  Common  Stock

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

                                       4

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, 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

and 3.5.

    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

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,

Parent  shall use its best efforts to cause Merger Sub not to issue any options,
warrants, calls, rights or  other securities, agreements  or commitments of  any
character  obligating Merger Sub to grant, extend or enter into any such option,

Merger Agreement  constitutes a  valid  and binding  obligation of  the  Company
enforceable against it in accordance with its terms except as enforcement 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 any proceeding therefor may be brought. Except for the
requisite  approval of the  holders of Company Common  Stock, no other corporate
proceedings on the part  of the Company are  necessary to authorize this  Merger
Agreement  and the transactions contemplated hereby. The execution, delivery and
performance of this Merger Agreement by the Company and the consummation by  the
Company  of  the  transactions contemplated  hereby  do  not and  will  not: (i)

of  time  or  both)  under,  or  give  to  others  any  rights  of  termination,
cancellation  or  acceleration of,  or result  in  the creation  of any  lien or

lease instrument or franchise to which the Company or its properties is bound or
affected other  than:  (A)  any breaches,  violations,  defaults,  terminations,
cancellations,   accelerations,   liens   or  encumbrances   which   would  not,

have a  Company Material  Adverse  Effect or  prevent  the consummation  of  the

compliance, with the provisions of the HSR Act, the Securities Act, the Exchange
Act,  the corporation, securities or Blue Sky laws or regulations of the various
states, and Applicable  Insurance Laws including,  without limitation, 8  V.S.A.
Sections 3431(a) and 3683, and other similar requirements in states in which the
Company is licensed as an insurance company or agency, no filing or registration
with,  or authorization, consent or approval of, any public body or authority is
necessary for  the  consummation by  the  Company of  the  Merger or  the  other
transactions   contemplated   hereby,   other   than   filings,   registrations,
authorizations, consents or approvals which if  not obtained or made would  not,
individually  or in  the aggregate,  have a  Company Material  Adverse Effect or
prevent the consummation of the transactions contemplated hereby and thereby.
 
    Section 5.5.  REPORTS AND FINANCIAL STATEMENTS.
 
    (a) The  Company  has made,  and  will prior  to  the Effective  Date  make,
available  to Parent true, complete and  correct copies of the Annual Statements
of the Company as filed with the insurance regulatory authorities in Vermont and
any other state in which such statements are required to be filed for the  three
years  ended December  31, 1993,  December 31, 1994  and December  31, 1995. The
balance sheets of the Company as of December 31, 1995, and the related summaries
of operations and statement of cash flows  for the year then ended, included  in
the  Annual Statements of the Company for  the year then ended, were prepared in
all  material  respects  in  conformity  with  Statutory  Accounting  Principles
consistently applied for the period covered thereby, were prepared in accordance
with  the books  and records  of the Company,  as the  case may  be, and present
fairly in all material respects the statutory financial position of the Company,
as the  case may  be,  as at  the  date thereof  and  the statutory  results  of
operations  of the Company, as the case may be, and other data contained therein
for the period then ended. The balance  sheets of the Company in respect of  any
period  ending after December 31, 1995,  and the related summaries of operations
and statements  of  cash  flows for  the  periods  then ended  included  in  the
Quarterly  Statements,  were prepared  in  conformity with  Statutory Accounting
Principles applicable  to  interim  financial  statements  consistently  applied
during  the periods involved, subject to normal year-end adjustments, and fairly
present in all material respects their respective statutory financial  positions
at  the respective dates and the  results of the Company's respective operations
for the periods then ended.
 
    (b) The  Company has  previously  furnished Parent  with true  and  complete
copies of its (i) Annual Reports on Form 10-KSB for the three fiscal years ended
December  31, 1992, December 31,  1993 and December 31,  1994, as filed with the
Commission; (ii) Quarterly Reports an Form  10-QSB for the quarters ended  March
31,  1995, June 30, 1995  and September 30, 1995,  as filed with the Commission;
(iii) proxy  statements related  to all  meetings of  its stockholders  (whether
annual  or  special) since  December 31,  1993,  and (iv)  all other  reports or
registration statements filed by the Company with the Commission since  December
31,  1994,  except  registration  statements  on Form  S-8,  which  are  all the
documents (other than  preliminary material)  that the Company  was required  to
file with the Commission since that date (the documents described in clauses (i)
through  (iv)  being  referred  to  herein  collectively  as  the  "Company  SEC
Reports"). As of their respective dates, the Company SEC Reports complied in all
material respects with the  requirements of the Securities  Act or the  Exchange
Act,  as  the case  may  be, and  the rules  and  regulations of  the Commission
thereunder applicable to such Company SEC Reports. As of their respective dates,
the Company SEC Reports did not contain any untrue statement of a material  fact
or  omit to state a material fact required  to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made,  not  misleading.  The  audited  consolidated  financial  statements   and
unaudited  interim financial statements  of the Company  included in the Company
SEC Reports comply as to form  with applicable accounting requirements and  with
the  published rules and regulations of  the Commission with respect thereto and
the financial statements included in the Company SEC Reports have been  prepared
in  accordance  with  generally  accepted  accounting  principles  applied  on a
consistent basis
 
                                       11
<PAGE>
(except  as may be indicated therein or in the notes thereto) and fairly present
in all material respects the financial position  of the Company as at the  dates
thereof  and the results  of their operations and  changes in financial position
for the  periods  then ended  subject,  in the  case  of the  unaudited  interim
financial  statements,  to  normal  year-end  audit  adjustments  and  any other
adjustments described therein.
 
    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
including,  but not limited to, the  reserves for incurred losses, incurred loss
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.
 
                                       14

    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,
are, to the Companys knowledge, valid and existing and represent monies due, and
the Company has made reserves reasonably considered adequate for receivables not
collectible  in the ordinary  course of business, and  (subject to the aforesaid
reserves) are subject  to no  material refunds or  other adjustments  and to  no
defenses,   rights  of   setoff,  assignments,   restrictions,  encumbrances  or
conditions enforceable  by third  parties on  or affecting  any material  amount
thereof.
 
    Section  5.17.  INVESTMENT PORTFOLIO AND OTHER  ASSETS.  The Company owns an
investment portfolio acquired in the ordinary course of business, and a true and
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
Disclosure Schedule. As of the date hereof, to the Company's knowledge: (i) none
of the investments included  in such investment portfolio  is in default in  the
payment  of principal or  interest or dividends  or impaired to  any extent, and
(ii) all  investments included  in  such investment  portfolio comply  with  all
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,
and  without any known conflict with the  rights of others. For purposes of this
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.
 
    Section 5.20.  INTERCOMPANY AND AFFILIATE TRANSACTIONS; INSIDER INTERESTS.
 
    (a) Except as otherwise disclosed in  the Company SEC Reports, Section  5.20
of  the  Company  Disclosure  Schedule  lists  all  intercompany  agreements  or

    (b) Except  as  otherwise disclosed  in  the  Company SEC  Reports,  to  the

direct or indirect interest, either by  way of stock ownership or otherwise,  in
any  firm, corporation, association or  business enterprise, which competes with
the Company, is a supplier, client, customer, agent or broker of the Company, or
is
 
                                       15
<PAGE>
otherwise engaged  in the  business  engaged in  by  the Company.  Ownership  of
capital  stock  listed  on  a  national securities  exchange  or  traded  in the
over-the-counter market of any  corporation shall not be  deemed a violation  of
this Section, provided the owner thereof and his affiliates do not own more than
an aggregate of ten percent of the capital stock of such corporation.
 
    Section  5.21.    EMPLOYEE  BENEFIT  PLANS.   Section  5.21  of  the Company
Disclosure Schedule lists all employee benefit or compensation plans, agreements
or arrangements, of any kind whatsoever, including "employee benefit plans,"  as
defined  in Section 3(3) of the Employee Retirement Income Security Act of 1974,
as amended, ("ERISA"), and including, but  not limited to, plans, agreements  or
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
aggregate, have a Company Material Adverse  Effect: (a) the consummation of  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
grievance  procedure,  unfair   labor  practice   proceedings,  arbitration   or
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
have been administered in accordance, and are in compliance, with all applicable
provisions of ERISA, the Code and other applicable law.
 
    Section  5.22.  ERISA.  Each of  the Company Benefit Plans which is intended
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
IV of ERISA.
 
    Section  5.23.   OFFICERS,  DIRECTORS AND  EMPLOYEES.   Except  as otherwise
disclosed in the  Company SEC Reports,  Section 5.23 of  the Company  Disclosure

to  (a) the Companys officers  and directors, and (b)  each other employee whose

or  who received or has accrued in respect  of such period a cash bonus equal to

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

Effective Date that would jeopardize the tax free nature of the transaction.
 
    Section  7.7.  INFORMATION IN DISCLOSURE DOCUMENTS, REGISTRATION STATEMENTS,
ETC.  Parent and the Company agree  that none of the information supplied by  it

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

be  required to adopt or maintain any plan or arrangement providing for the sale
of the Parent Common Stock or Company Common Stock.

parties  hereto, by or  pursuant to action  taken by their  respective Boards of

                          AGREEMENT AND PLAN OF MERGER
 
    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

       warranties  or obligations under this Merger Agreement or responsible for
       the failure of the Merger to occur on or before such date)."

    in full force and effect.
 
         4.  This Amendment may be executed in one or more counterparts, each of

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.
