Dear Dencor Energy Cost Controls, Inc. Shareholder:

     You are cordially  invited to attend a Special  Meeting of  Shareholders of
Dencor Energy Cost Controls,  Inc.  ("Dencor"),  which will be held at 1450 West
Evans, Denver, Colorado 80223, at _____ a.m., Denver time, on _______, _________
__, 1997.

     At the  Special  Meeting,  you  will be asked to  approve  certain  matters
related to the  proposed  merger (the  "Merger")  of Proven  Alternatives,  Inc.
("PAI") with and into Dencor Acquisition  Corporation ("Sub"), which will result
in PAI's  being the  surviving  corporation  and a  wholly-owned  subsidiary  of
Dencor.  Specifically,  you will be asked to  consider  and vote upon a proposal
recommended  by the Board of  Directors  of  Dencor to do each of the  following
simultaneously  at the time of the Merger:  (i) effect a 1-for-50  reverse stock
split (the "Reverse Stock Split") of the  outstanding  shares of Dencor's common
stock so that each 50 shares of  outstanding  common  stock,  no par  value,  of
Dencor  ("Dencor Common Stock") shall be deemed to be one share of common stock,
no par  value,  and (ii)  amend  Dencor's  Articles  of  Incorporation  to:  (A)
authorize  Dencor to issue an aggregate of 1,000,000  shares of preferred  stock
with such preferences, conversion and other rights, voting powers, restrictions,
limitations  as to  distributions,  qualifications,  and terms and conditions of
redemption as shall be approved by the board of directors of Dencor,  and (B) to
change the name of the corporation  from "Dencor Energy Cost Controls,  Inc." to
"Proven Alternatives Inc." (collectively, the "Charter Amendments").  References
in the accompanying Joint Proxy Statement/Prospectus to numbers of shares are to
numbers of shares prior to the Reverse Stock Split.

     Pursuant to the terms of the Merger  Agreement,  each outstanding  share of
Common Stock of PAI will be converted  into 1.5 shares of Common Stock of Dencor
before  giving  effect to the Reverse Stock Split (.03 shares of Common Stock of
Dencor after giving  effect to the Reverse Stock  Split).  No fractional  shares
will be  issued  in  connection  with  the  Merger.  In lieu  thereof,  each PAI
stockholder  entitled to receive 0.5 or more of a share of Dencor  Common  Stock
shall  receive the total number of whole shares of Dencor  Common Stock to which
he or she is entitled and a single  whole share of Dencor  Common Stock in place
of the fractional  share.  Each PAI stockholder who would be entitled to receive
less than 0.5 of a share of Dencor  Common  Stock shall  receive  only the total
number of whole shares to which he or she is entitled,  and any such  fractional
share  shall  be  eliminated  for  all  purposes  without  compensation  for the
fractional share.

     The effect of your  approval  of the  Reverse  Stock  Split and the Charter
Amendments  will be to enable Dencor to complete the Merger with PAI. The Merger
is  described  in  the  accompanying  Joint  Proxy  Statement/Prospectus,  which
includes  a summary of the terms of the Merger  and  certain  other  information
relating to the proposed transaction.

this Joint Proxy Statement/Prospectus. Reference is made to, and this summary is
qualified  in its  entirety  by,  the more  detailed  information  contained  or
incorporated  by reference  in this Joint Proxy  Statement/  Prospectus  and the
Annexes hereto.

     As used  herein,  unless the context  otherwise  requires,  "Dencor"  means
Dencor  Energy  Cost  Controls,   Inc.,  "Sub"  refers  to  Dencor   Acquisition
Corporation,  a  wholly-owned  subsidiary  of  Dencor,  and "PAI"  means  Proven
Alternatives, Inc. and its consolidated subsidiaries.

                            -------------------------

     Shareholders of Dencor and stockholders of PAI are urged to read this Joint
Proxy  Statement/Prospectus  in its entirety,  and should carefully consider the
information set forth below under the heading "RISK FACTORS".

                            -------------------------

The Companies

     Dencor Energy Cost Controls,  Inc.  Dencor was  incorporated on January 16,
1974 under the laws of the State of  Colorado  for the  purpose  of  developing,
manufacturing,  and marketing  electronic devices.  Currently,  Dencor's primary
activity is the  manufacture  and sale of  electrical  demand  controllers  that
manage  electricity  consumed in residences  and commercial  establishments  and
energy  control  devices  used by  utilities  to modify  residential  energy use
patterns. Dencor has its headquarters,  production facilities,  and research and
development laboratories in Denver, Colorado.

     Dencor is  engaged in only one  industry,  that of  designing,  developing,
manufacturing,  marketing,  and  installing  products and systems that assist in
controlling  the cost of  energy  utilization.  Management  of  Dencor  does not
recognize any significant  business  difference,  at least at this time, between
sales of residential demand controllers,  special relay equipment for utilities,
temperature   activated  duty  cyclers,   commercial  demand  controllers,   and
interlocks.

     Dencor's  primary business is the assembly and sale of control systems that
reduce  electrical  energy costs. Its principal product is the electrical demand
controller  that  enables a  homeowner  having an electric  heating  system or a
central air  conditioning  system to control the peak use of  electricity.  This
enables the homeowner to achieve cost savings in geographic  locations served by
electric  utilities  that include a demand factor in their  residential  billing
rates.  Demand rates are used by electric  utilities  to encourage  consumers to
reduce their peak usage of electricity.

     A demand  controller  monitors  the total power  consumption  and turns off
selected loads,  typically  heating circuits,  during peak consumption  periods,
restoring them at the end of that period. The controller automatically keeps the
consumption  within the level  selected.  The principal  markets for residential
demand control systems are in regions served by utilities with a demand rate for
residential  customers.  The residential demand controller is designed for homes
heated electrically by baseboard heaters,  radiant heaters, heat pumps, electric
boilers and electric furnaces, and may also be used to control air conditioners.


                                        3



<PAGE>

     The sale of residential demand control systems  contributed 73% of Dencor's
total sales during 1996.

     Dencor has developed demand controllers for commercial buildings. One model
of the commercial  systems  includes a graphics  system to interface  commercial
demand controllers to IBM compatible computers. This graphics system can display
minute-by-minute  demand data as well as 15-minute,  daily,  monthly, and annual
summaries.  All data is also stored on computer disk for later  inspection.  The
sale of commercial demand control systems  contributed 16% of total Dencor sales
during 1996.

     Dencor has developed a series of products  used to control  water  heaters,
space heaters, and air conditioners for specific utility applications.  Sales of
these products accounted for 11% of net sales in 1996.

     The  executive  offices of Dencor are located at 1450 West  Evans,  Denver,
Colorado 80223 and its telephone number is (303) 922-1888.

     Sub was  organized  as a Delaware  corporation  in 1997 for the  purpose of
consummating  the Merger and the other  transactions  contemplated by the Merger
Agreement.  Sub has no assets or business and has not carried on any  activities
to date other than incident to its  formation and in connection  with the Merger
and the other transactions  contemplated by the Merger Agreement.  Sub's offices
are located at 1450 West Evans, Denver, Colorado 80223, and its telephone number
at that address is (303) 922- 1888.

     Proven Alternatives, Inc. PAI was incorporated in April 1991 under the laws
of the State of California and was subsequently reincorporated under the laws of
the State of Delaware in November  1991.  In July 1991,  PAI acquired 85% of the
outstanding  capital stock of Golden Bear Cogen, Inc. ("Golden Bear"); in August
1996 PAI acquired the remaining 15% of the  outstanding  capital stock of Golden
Bear.  In April 1992 the Company  acquired  100% of Luminae,  Inc.  ("Luminae").
Luminae  is a  wholly  owned  operating  subsidiary  of  PAI,  concentrating  in
specialized  lighting design.  Proven Alternatives  Capital Corporation ("PACC")
was  incorporated as a wholly owned subsidiary of PAI and is intended to develop
investment vehicles and provide related services for sophisticated institutional
investors in order to provide  project  financing for PAI. In February 1992, PAI
acquired Puget Energy Services,  Inc.  ("PESI"),  a company  specializing in the
execution of energy efficiency  projects under utility contracts.  Subsequently,
in March 1994, PAI merged PESI into PACC.

     PAI is an  integrated  energy and  process  management  firm.  It  provides
process   knowledge,   energy   management   capabilities,   energy   efficiency
technologies  and capital  capabilities to solve business  problems  relating to
energy  usage.  PAI  provides its  services in six service  areas:  total energy
management,  strategic consulting,  program management, capital services, energy
procurement and energy information  management.  Typically services are provided
by PAI as a long-term  partner  with the customer  and on a  performance  basis.
PAI's services include the identification of under-performing  corporate assets,
the recommendation for and application of processes, equipment and techniques to
improve the  performance of these assets and  investment in these  applications.
PAI markets its  services to companies  that could  benefit  significantly  from
improvements in energy management, energy procurement and use and to those whose
operations are energy and process  intensive.  These clients are located both in
the United States and abroad.

     PAI's  principal  executive  offices are located at 1740 Army  Street,  San
Francisco, California 94124, and its telephone number is (415) 285-0800.

one share of common  stock of  Dencor,  no par value,  and (ii)  amend  Dencor's
Articles of  Incorporation  to (1)  authorize  Dencor to issue an  aggregate  of
1,000,000  shares of preferred  stock (the "Dencor  Preferred  Stock") with such

limitations  as to  distributions,  qualifications,  and terms and conditions of
redemption  as shall be approved by the Board of  Directors  of Dencor,  and (2)
change the name of Dencor from "Dencor  Energy Cost  Controls,  Inc." to "Proven
Alternatives  Inc."  upon the  consummation  of the  Merger  (collectively,  the

will also  consider and vote upon any other matter that may properly come before
the Dencor Special Meeting or at any  adjournments  and  postponements  thereof.

numbers of shares prior to the Reverse Stock Split unless otherwise indicated.

     PAI Special Meeting.  At the PAI Special Meeting,  holders of shares of PAI
Common  Stock will  consider  and vote upon a proposal  to approve and adopt the
Merger Agreement, providing for the Merger of PAI with and into Sub, with PAI to
be the  surviving  corporation  in the Merger and a  wholly-owned  subsidiary of

Votes Required

     Dencor.  The approval of the Reverse Stock Split and the Charter Amendments
requires the affirmative vote of a majority of the outstanding  shares of Dencor
Common Stock.

Reverse Stock Split and the Charter  Amendments.  In addition,  brokers who hold
shares of Dencor Common Stock as nominees will not have discretionary  authority
to vote such shares in the absence of  instructions  from the beneficial  owners
thereof. Votes which are not cast for this reason ("broker non-votes") will also
have the effect of a vote against the proposal. See "THE SPECIAL MEETINGS--Votes

Stock  in favor  of the  matters  submitted  to  stockholders  of PAI at the PAI
Special Meeting.

The Reverse Stock Split

     Effect of the Reverse  Stock Split.  If the Reverse Stock Split is approved
by the Dencor shareholders,  the effective time for the Reverse Stock Split will
be immediately before the Effective Time of the Merger. Each 50 shares of Dencor
Common Stock at that time shall be deemed to be one share of Dencor Common Stock
without further action by the Dencor shareholders.

     If the Reverse Stock Split is effected,  Dencor will not issue certificates
for fractional shares.  Instead persons who are Dencor shareholders  immediately
before the Effective Time of the Merger and who otherwise would be entitled to a
fractional  share will be issued one whole share for that fractional  share. See
"THE REVERSE STOCK SPLIT".

     Certain  Federal  Income  Tax  Consequences.  For U.S.  federal  income tax
purposes,  it is  anticipated  that no gain or loss will be recognized by Dencor
shareholders  as a result of the Reverse  Stock Split.  See "THE  REVERSE  STOCK
SPLIT".

     Recommendations of the Board of Directors of Dencor. The Board of Directors
of Dencor  believes that the Reverse Stock Split is in the best interests of the
Dencor shareholders and has unanimously approved the Reverse Stock Split.

     The Board of Directors of Dencor unanimously recommends that the holders of
Dencor Common Stock approve the Reverse Stock Split.

The Merger

     Effect of  Merger.  At the  effective  time of the Merger  (the  "Effective
Time"),  Sub will be  merged  with and into  PAI,  which  will be the  surviving
corporation  in the Merger  (the  "Surviving  Corporation").  As a result of the


                                        6



<PAGE>


Merger, PAI will become a wholly-owned  subsidiary of Dencor. Subject to certain
provisions as described herein with respect to shares owned by PAI, Dencor,  Sub
and the  subsidiaries  of PAI, each issued and  outstanding  share of PAI Common
Stock will be converted into 1.5 (the "Exchange  Ratio") validly  issued,  fully
paid and nonassessable shares of Dencor Common Stock in the Merger before giving
effect to the Reverse  Stock Split (.03 shares of Common  Stock of Dencor  after
giving effect to the Reverse Stock Split).  No fractional  shares will be issued
in connection with the Merger. In lieu thereof, each PAI stockholder entitled to
receive 0.5 or more of a share of Dencor  Common  Stock shall  receive the total
number of whole shares of Dencor Common Stock to which he or she is entitled and
a single whole share of Dencor  Common Stock in place of the  fractional  share.
Each PAI  stockholder  who would be entitled to receive less than 0.5 of a share
of Dencor  Common  Stock shall  receive only the total number of whole shares to
which he or she is entitled,  and any such fractional  share shall be eliminated
for all  purposes  without  compensation  for the  fractional  share.  See  "THE
MERGER--Fractional Shares."

     Recommendations  of the  Boards  of  Directors.  The  respective  Boards of
Directors of Dencor and PAI believe that the terms of the Merger are fair to and
advisable and in the best interests of their  respective  stockholders  and have
unanimously  approved  the Merger  Agreement,  the Merger and the other  related
transactions.

     The Board of Directors of Dencor unanimously recommends that the holders of
Dencor Common Stock approve the Charter Amendments and the Reverse Stock Split.

     The Board of Directors of PAI  unanimously  recommends  that the holders of
PAI Common Stock approve and adopt the Merger Agreement and the Merger.

     For additional  information with respect to the determinations  made by and
the  recommendations  of the  Dencor  and PAI  Boards  of  Directors,  see  "THE
MERGER--Recommendations of the Boards of Directors; Reasons for the Merger."

     Effective  Time of the Merger.  The Merger will become  effective  upon the
filing and  acceptance of the  Certificate of Merger with the Secretary of State
of the State of Delaware or such later date as is specified in such Certificate.
The  filing of the  Certificate  of  Merger  will  occur as soon as  practicable
following the  satisfaction  or waiver of the conditions set forth in the Merger
Agreement.  See "CERTAIN PROVISIONS OF THE MERGER  AGREEMENT--Conditions  to the
Merger."

     Interests of Certain Persons in the Merger. Shares of PAI Common Stock held
by  executive  officers and  directors  of PAI will be  converted  into the same
consideration  as shares of PAI  Common  Stock  held by other  stockholders.  In
addition,  the Merger  Agreement  provides  that PAI will enter into  employment
agreements with each of Maynard L. Moe,  President and a Director of Dencor, and
Theodore  A.  Hedman,  Vice  President  and a  Director  of  Dencor.  The Merger
Agreement also states that PAI will provide Dencor with sufficient  funds to pay
outstanding  loans,  including  loans made to Dencor by Dr. Moe, Mr.  Hedman and
their relatives.

     Conditions  to the  Merger.  The  obligations  of  Dencor,  PAI  and Sub to
consummate the Merger are subject to various conditions,  including, among other
things,  obtaining the requisite stockholder approvals, the effectiveness of the
Registration  Statement and the absence of any order or other legal restraint or
prohibition preventing the consummation of the Merger.

     Termination of the Merger Agreement. The Merger Agreement may be terminated
at any time prior to the Effective Time (i) by mutual consent of Dencor, PAI and
Sub, (ii) by either Dencor or PAI (1) if any court or other governmental  entity


                                        7



<PAGE>


shall have issued a final and nonappealable order, decree or ruling or taken any
other  final  and  nonappealable  action  permanently   enjoining  or  otherwise
prohibiting the Merger,  (2) if the Merger shall not have been consummated on or
before  December 31, 1997 (other than due to the failure of the party seeking to
terminate  the Merger  Agreement  to perform  its  obligations  under the Merger
Agreement  required to be performed at or prior to the Effective  Time),  or (3)
if, under  certain  circumstances,  the required  stockholder  approvals are not
obtained,  and (iii) by Dencor or PAI in certain other situations.  See "CERTAIN
PROVISIONS OF THE MERGER AGREEMENT".

     Right Of  Shareholders/Stockholders  To Dissent.  Dencor's  management  has
concluded that,  because Dencor is not a constituent  corporation in the Merger,
the  shareholders  of Dencor are not entitled to dissent and obtain  payment for
their shares from Dencor.  However, it is possible that one or more shareholders
of Dencor may challenge the denial of dissenters  rights to the  shareholders of
Dencor,  and such  challenge  could result in litigation  between Dencor and the
challenging  shareholders.  The outcome of any such  litigation is uncertain and
could result in a decision denying or granting  dissenters  rights of appraisal.
If and to the extent that  dissenters  rights are claimed and granted,  it would
result in an outflow of cash from,  and a decrease in the number of  outstanding
shares of, Dencor. See "THE MERGER--Dissenting  Shareholders/Stockholders Rights
Of Appraisal".

     Because PAI is a constituent  corporation to the Merger,  PAI's  management
believes that the Delaware  General  Corporation Law (the "DGCL")  provides that
each  shareholder of PAI who objects to the Merger is entitled to obtain payment
of the fair value of his or her shares of PAI. In order to assert these  rights,
a  shareholder  of PAI is  required  to adhere  strictly  to  certain  statutory
requirements  set forth in the DGCL. Any deviation from the  requirements of the
DGCL may result in the forfeiture of a dissenting  shareholder's right to obtain
payment  for his or her shares.  See "THE  MERGER--Dissenting  PAI  Stockholders
Rights Of Appraisal".

     See Appendix II to this Joint Proxy  Statement/Prospectus for a copy of the
provisions of the Delaware General Corporation Law concerning  dissenters rights
of appraisal.

     Certain  Federal  Income  Tax  Consequences.  For U.S.  federal  income tax
purposes,  it is anticipated that the Merger will qualify as a  "reorganization"
within the meaning of Section  368(a) of the Internal  Revenue Code of 1986,  as
amended (the  "Code"),  no gain or loss will be recognized by Dencor or PAI as a
result of the Merger and no gain or loss will be recognized by  stockholders  of
PAI who are United  States  persons  (within  the  meaning of the Code) upon the
conversion of their PAI Common Stock into shares of Dencor Common Stock pursuant
to the Merger.

     Special  rules may  apply to a holder of PAI  Common  Stock  who,  for U.S.
federal  income tax purposes,  is a  non-resident  alien  individual,  a foreign
corporation,  a foreign partnership or a foreign estate or trust. Each holder of
PAI  Common  Stock  should  consult  his  own  tax  advisor  regarding  the  tax
consequences  of the Merger in light of such holder's own  situation,  including
the application  and effect of any state,  local or foreign income and other tax
laws. For a discussion of these and other federal income tax  considerations  in
connection  with  the  Merger,  see  "THE  MERGER--Certain  Federal  Income  Tax
Consequences."

     Accounting  Treatment of the Merger. The Merger is expected to be accounted
for as a "pooling of interests" in accordance with generally accepted accounting
principles. See "THE MERGER--Anticipated Accounting Treatment."

     Comparison  of Rights of  Holders of PAI  Common  Stock and  Dencor  Common
Stock.  See  "COMPARISON  OF RIGHTS OF HOLDERS  OF PAI  COMMON  STOCK AND DENCOR

COMMON  STOCK" for a summary of the material  differences  between the rights of
holders of PAI Common Stock and Dencor Common Stock.

     Other  Significant  Considerations.  In determining  whether to approve the
transactions  pursuant to the Merger  Agreement and other related  transactions,
Dencor  shareholders and PAI stockholders  should consider that the price of the
Dencor Common Stock at the  Effective  Time as well as the prices at the date of
this Joint Proxy  Statement/Prospectus  and at the date of the Special  Meetings
may vary as a result of changes in the  business,  operations  or  prospects  of
Dencor, market assessments of the likelihood that the Merger will be consummated
and the  timing  thereof,  general  market  and  economic  conditions  and other
factors.  Because the Effective  Time may occur at a later date than the date of
the Special  Meetings,  there can be no assurance that the sales price of Dencor
Common Stock on the date of the Special Meetings will be indicative of the sales
price of Dencor Common Stock at the  Effective  Time.  The  Effective  Time will
occur  as soon as  practicable  following  the  satisfaction  or  waiver  of the
conditions  set forth in the Merger  Agreement.  See "CERTAIN  PROVISIONS OF THE
MERGER AGREEMENT--Conditions to the Merger."

     Stockholders of PAI should also consider that the Exchange Ratio is a fixed
ratio in the  Merger  Agreement.  As a result,  the  Exchange  Ratio will not be
adjusted in the event of a decline or increase in the market price of the Dencor
Common  Stock.  Dencor  shareholders  and PAI  stockholders  are urged to obtain
current market quotations for the Dencor Common Stock.

     PAI stockholders  should also consider that the rights of holders of Dencor
Common  Stock  differ in a number of  significant  respects  from the  rights of
holders of PAI Common Stock. For a discussion of the rights of the Dencor Common
Stock, see "DESCRIPTION OF CAPITAL STOCK OF DENCOR" and "COMPARISON OF RIGHTS OF
HOLDERS OF PAI COMMON STOCK AND DENCOR COMMON STOCK."

     The shares of Dencor Common Stock issued to stockholders of PAI pursuant to
the Merger  Agreement  will  comprise  approximately  92% of the total number of
shares  of  Dencor  Common  Stock  issued  and  outstanding   after  the  Merger
(approximately  93% on a  fully  diluted  basis  assuming  the  exercise  of all
outstanding  PAI stock  options for 4,591,284  shares of Dencor  Common  Stock).
Immediately  prior to the Effective Time, there will be approximately  3,671,304
shares of Dencor  Common Stock issued and  outstanding.  Following the Effective
Time, there will be  approximately  915,972 shares of Dencor Common Stock issued
and  outstanding  after  giving  effect to the Reverse  Stock Split  (45,127,272
before the Reverse Stock Split).

     Management After the Merger.  After the Merger,  the following persons will
have the  positions  and offices  with Dencor as  designated:  Charles T. Condy,
Chairman  of the  Board and  Chief  Executive  Officer;  Christopher  T.  Condy,
Director,  President  and Chief  Operating  Officer;  Theodore A.  Hedman,  Vice
President of Dencor Division;  Maynard L. Moe,  Director of Dencor and President
of Dencor Division;  George F. Pilloton,  Director and Chief Financial  Officer.
Dr. Moe and Mr.  Hedman will  continue to manage the Dencor  Division  after the
Merger,  which will  consist of the  business  operated  by Dencor  prior to the
Merger.  The current  officers and directors of PAI will retain their respective
positions with PAI after the Merger. The manner in which the business operations
of each of  Dencor  and PAI  will be  conducted  after  the  Merger  is  further
discussed in "POST-MERGER PROFILE AND STRATEGY".

                  NOTES TO SELECTED CONSOLIDATED FINANCIAL DATA


1.   The pro forma  combined  per share data for income  (loss) from  continuing
     operations  has been  calculated  using pro forma  combined  average shares
     outstanding.  PAI and Dencor pro forma combined average shares  outstanding
     have been calculated using the number of Dencor average shares  outstanding
     during the periods presented, increased by the anticipated number of shares
     of Dencor common stock to be issued to PAI  shareholders  using an Exchange
     Ratio of 1.5, for each share of PAI Common Stock deemed  outstanding during
     each of the periods  presented as if these shares were  outstanding for the
     entire period  presented.  The weighted  average shares deemed  outstanding
     calculation for PAI does not include shares issuable upon exercise of fully
     paid,  fully  vested stock  options as such shares would be  anti-dilutive.
     Such  options  would  increase  weighted  average  shares   outstanding  by
     approximately  1,592,000  shares for the three  months ended March 31, 1997
     and 1996 and the years ended December 31, 1996 and 1995,  1,629,000  shares
     for the year ended  December 31, 1994,  and  1,346,000  shares for the nine
     months ended December 31, 1993.

2.   The pro forma combined book value per share data has been calculated  using
     pro forma combined shares outstanding.

3.   PAI's loss from continuing operations, net loss, working capital, long-term
     obligations,   stockholders'   equity   (deficit),   loss  from  continuing
     operations  per common  share,  and book value per share have been restated
     for the year ending  December 31, 1994 and the nine months  ended  December
     31, 1993, to reflect adjustments in deferred tax accruals in those periods.
     The impact of the  restatement  was to  decrease  the loss from  continuing
     operations  and reduce the related  deferred tax  liability by $799,000 for
     the nine months  ended  December  31,  1993,  and to increase the loss from
     continuing  operations  and  current  taxes  payable by $5,000 for the year
     ended December 31, 1994.

4.   Financial  data as of December 31, 1994,  December 31, 1993,  and March 31,
     1993,  reflects  the  reclassification  of fully paid,  fully  vested stock
     options  from  long-term   liabilities  to   stockholders'   equity.   Such
     reclassifications    decreased   long-term    liabilities   and   increased
     stockholders'   equity  by  approximately   $1,158,100,   $1,268,300,   and
     $1,458,600 as of December 31, 1994,  December 31, 1993, and March 31, 1993,
     respectively.

5.   In 1993,  PAI changed  its fiscal  year from March 31 to December  31. As a
     result,  pro forma  information  for the year ended  December  31, 1993 was
     calculated  based on PAI's financial  information for the nine months ended
     December 31, 1993.  Pro forma  information  for the year ended December 31,
     1992 was calculated based on PAI's financial information for the year ended
     March 31, 1993.

6.   The equivalent pro forma PAI per share  information  has been calculated by
     multiplying  the pro forma  combined per share data by an Exchange ratio of
     1.5.

7.   Pro forma  financial  data does not  reflect  the  proposed 50 to 1 reverse
     stock split subject to shareholder approval.

8.   Pro forma  financial  data does not reflect  the  effects of the  potential
     preferred stock issuance or other issuance of securities.  See "POST-MERGER
     PROFILE AND STRATEGY".

9.   Long-term  obligations  for PAI include non  recourse  debt secured by long
     term receivables. Such long-term non recourse debt obligations  amounted to
     approximately $22.5 million,  $17.8 million, $8.4 million, and $6.1 million
     as of December 31, 1996, 1995, 1994, and 1993,  respectively.  At March 31,
     1997 and 1996, long-term  obligations included  approximately $21.1 million
     and $20.7 million of non recourse debt, respectively.

10.  Supplemental loss from continuing  operations per common share reflects the
     impact of the proposed 50 to 1 reverse stock split  subject to  shareholder
     approval  and was  calculated  by  multiplying  the  loss  from  continuing
     operations per common share by an exchange ratio of 50.

     On December 13, 1996,  the last day before the public  announcement  of the
Merger on June 3,  1997 on which a trade  occurred,  the low bid and high  asked
prices of the Dencor  Common  Stock  obtained by Dencor from  brokers who make a
market  in  Dencor's  securities  were  $.04  per  share  and  $.08  per  share,
respectively.

     Recent bid and asked prices of the Dencor Common Stock are set forth on the
cover page of this Joint Proxy Statement/Prospectus.

          There  currently is not any public  trading  market for the PAI Common
Stock. PAI has not paid dividends on the PAI Common Stock.

          Dencor  shareholders  and PAI stockholders are urged to obtain current
market quotations for the Dencor Common Stock.

          Dividend  Policy of Dencor  Following  the  Merger.  After the Merger,
Dencor does not expect to pay dividends on the Dencor Common Stock, although the
Board of Directors  of Dencor may  determine in the future to modify such policy
depending  on various  factors,  including  Dencor's  earnings,  then current or
anticipated  cash needs and any other factors that the Board of Directors  deems
relevant.

                                  RISK FACTORS

     THE SECURITIES  OFFERED HEREBY ARE SPECULATIVE AND INVOLVE A HIGH DEGREE OF
RISK. BEFORE MAKING AN INVESTMENT DECISION CONCERNING THE MERGER OF SUB WITH AND
INTO PAI, WITH PAI'S BECOMING A WHOLLY-OWNED  SUBSIDIARY OF DENCOR,  THE HOLDERS
OF PAI COMMON STOCK  SHOULD GIVE CAREFUL  CONSIDERATION  TO THE  FOLLOWING  RISK
FACTORS AFFECTING THE BUSINESS OF DENCOR AND ITS SECURITIES, TOGETHER WITH OTHER
INFORMATION IN THIS JOINT PROXY STATEMENT/PROSPECTUS.

1. No  Independent  Appraisal  of Terms of  Merger.  Although  the  terms of the
Merger,  including  the  Exchange  Ratio  upon  which PAI  Common  Stock will be
exchanged for Dencor Common Stock, were the result of arm's length  negotiations
between  the  representatives  of PAI and of  Dencor,  neither  the terms of the
Merger nor the Exchange  Ratio were  determined  on the basis of an  independent
appraisal,  or a third party  opinion  concerning  the relative  values,  of the
businesses   and   assets   of   PAI   or   Dencor   as  a   whole.   See   "THE
MERGER-Recommendations of the Boards of Directors, Reasons for the Merger."

2.  Management.  The ability and experience of certain  individuals  who will be
engaged in the  management  and  operation  of PAI and Dencor  after the Merger,
particularly  Dr. Maynard L. Moe, Mr. Theodore A. Hedman,  Mr. Charles T. Condy,
Mr. Christopher T. Condy, and George F. Pilloton,  are crucial to the success of
PAI and Dencor. PAI has not entered into written or formal employment agreements
with Messrs.  Condy, Condy and Pilloton.  Dencor has not entered into written or
formal  employment  agreements with Dr. Moe or Mr. Hedman.  However,  the Merger
Agreement,  provides that PAI will enter into employment agreements with each of
Dr.  Moe and Mr.  Hedman  prior  to the  Closing  of the  Merger.  See  "CERTAIN
PROVISIONS OF THE MERGER AGREEMENT-Employment  Agreements". The loss of services
of any  of  these  individuals  would  have a  material  adverse  affect  on the
businesses of PAI and Dencor. The success of PAI and Dencor will also depend, in
part, upon its ability in the future to retain current  personnel and to attract
additional qualified operating, marketing and financial personnel.

3.  Control by PAI  Stockholders.  Following  consummation  of the  Merger,  PAI
officers,  directors and principal  stockholders with whom certain directors are
affiliated will  beneficially own or control in the aggregate  23,502,447 shares
of Dencor Common Stock (including 2,686,824 shares issuable upon the exercise of
options held by the PAI executive  officers and directors) or approximately 72.7
percent of the outstanding shares of Dencor's Common Stock after the Merger. See
"SECURITY OWNERSHIP OF MANAGEMENT AND CERTAIN BENEFICIAL  OWNERS".  Accordingly,
such PAI officers,  directors and principal stockholders,  if acting in concert,
will be able to elect all of Dencor's directors,  and affect the outcome of most
corporate actions requiring shareholder approval.



                                       16




<PAGE>


4. Dilution. If the Merger is consummated, the present PAI stockholders will own
93 percent of the  outstanding  common stock of Dencor and the  existing  Dencor
shareholders will own approximately 7 percent of the outstanding common stock of
Dencor.  The  pro  forma  book  value  per  share  of  Dencor  Common  Stock  at
________________,  1997 would be diluted from  approximately  $____________  per
share to approximately $___________ per share.

5.  Substantial  Doubt About  Dencor's  Ability to Continue as a Going  Concern.
Dencor's  auditors' report for its 1996 financial  statements  contains a "going
concern"  limitation.  Dencor's  operating  results  for the  fiscal  year ended
December  31,  1996  resulted in a net loss of $74,400.  At December  31,  1996,
Dencor had a shareholders  deficit and working capital deficiency of $11,300 and
$16,700, respectively. Dencor has also experienced difficulty and uncertainty in
meeting  its  liquidity  needs.  These  factors  raise  substantial  doubt about
Dencor's  ability to continue as a going  concern.  Dencor's 1997 operating plan
includes  achieving  increased  sales goals and  maintaining  its cost reduction
program,  which primarily includes a reduction of labor costs. Dencor management
believes that actions  presently being taking under its 1997 operating plan will
enable Dencor to achieve  profitability  during 1997 and  preliminary  financial
information  indicates that Dencor operated at a small profit for the six months
ended June 30, 1997. However, there is no assurance that Dencor will continue to
operate at a profit.

6. Substantial  Doubt About PAI's Ability to Continue as a Going Concern.  PAI's
auditors'  report for its 1996 financial  statements  contains a "going concern"
limitation.  PAI's operating results for the fiscal year ended December 31, 1996
resulted  in a  net  loss  of  $4,549,794.  At  December  31,  1996,  PAI  had a
stockholder's deficit and a negative working capital of $9,281,562 and $697,676,
respectively.  PAI experienced a decline in revenue and sustained losses in 1996
in conjunction with management's  decision to reengineer the marketing direction
of PAI towards large programs and energy management rather than single projects.
PAI management recognized that this reengineering would adversely affect results
in the near term,  and believes  the shift in  marketing  of PAI's  programs and
processes is now leading to the development of long term strategic relationships
that are taking shape in 1997 and into 1998.  PAI's future  success and economic
viability  will directly  relate to achieving  profitable  operations,  managing
tight liquidity,  and continuing to develop capital  resources.  PAI anticipates
meeting liquidity needs through growth in business and nonrecourse  financing of
long term energy  savings and finance  receivables.  Energy  savings and finance
receivables  consist of amounts due from customers  pursuant to long term energy
savings  contracts.  Customer  payments  are based upon a  percentage  of actual
energy savings provided.  Because energy savings realized are exceeding original
projections  for certain  projects,  PAI management  estimates that the economic
value of these receivables to be approximately  $29.9 million as of December 31,
1996, thereby exceeding book value by approximately $6.9 million.  This estimate
is based on the average  billings in 1996,  assuming such levels of  performance
will  be  sustained  for the  remaining  term of the  project,  and  using a 16%
discount  rate.  Additionally,  PAI expects to raise  capital  through a private
offering of preferred stock to be completed in the latter part of 1997. However,
there is no assurance that PAI management's  belief  concerning the estimates of
the  economic  value of the  energy  savings  receivables  is  accurate  or will
actually be  realized  due to credit and  performance  risks or that the private
placement of preferred stock will be consummated.


                                       17

7.  Developments  in  Technology.  The  industry in which each of PAI and Dencor
conduct business is characterized by rapidly developing  technology.  Changes in
technology  could affect the market for each of PAI's and Dencor's  products and
necessitate additional improvements and developments to such products. There can
be no  assurance  that  either of PAI's or  Dencor's  research  and  development
activities will lead to the successful  introduction of new or improved products
or that delays or problems in connection therewith will not be encountered.  The
cost  of  completing  new   technologies   to  satisfy   minimum   specification
requirements,  quality and delivery  expectations may exceed original  estimates
that could adversely affect operating results during any financial period.

8. Limited Financial Resources of Dencor. Dencor has limited financial resources
available  to it, and this may  restrict  Dencor's  ability to grow.  Additional
capital from sources  other than  Dencor's cash flow may be necessary to develop
new products,  and there is no assurance  that such  financing will be available
from any source.  Dencor management believes that it may not be able to increase
Dencor's  business as desired  without  additional  funding.  Dencor  management
believes  that the Merger will  result in a combined  entity that will be better
able to obtain financing, although there is no assurance that this will occur.

9. Competition. The industry in which each of PAI and Dencor conduct business is
highly  competitive.  Many of the  competitors of PAI and Dencor are established
enterprises that possess greater name  recognition,  established  customer bases
and  significantly  greater  resources  than each of PAI and Dencor and  compete
directly  with  PAI  and  Dencor  for  the  same  customers.  There  are not any
substantial  barriers to the entry of  additional  competitors  into the market.
Given  these  factors,  particularly  in the  approaching  environment  which is
expected to result from the deregulation of the electric  industry in the United
States,  it is highly  likely  that new  competitors  may emerge  and  acquire a
significant  portion  of each of PAI's and  Dencor's  market  share,  therefore,
further  diminishing  the prospects of PAI and Dencor.  PAI and Dencor  believe,
however,  that they will have certain  advantages  in  attempting to develop and
market their products and services  including a more cost effective  technology,
the  ability  to  undertake  smaller  projects,  and the  ability  to respond to
customer  requests  more  quickly  than  some  larger  competitors.  There is no
assurance that these conclusions will prove correct.

10.  Government  Regulation.  Each of PAI and Dencor are  subject to  government
regulation  of their  respective  business  operations  in general.  There is no
assurance that subsequent changes in the laws or regulations will not affect the
operations of PAI and Dencor.

11. The Illiquidity of an Investment and Limitation on Transferability. Although
the Dencor Common Stock is traded in the  over-the-counter  market and is quoted
in the "pink sheets" distributed by the National Quotation Bureau ("NQB"), there
currently  is not an active or liquid  market for the Common  Stock.  The Common
Stock has not traded since July 29,  1997,  at which time the "pink sheet" quote
for the Common Stock was $.04 bid and $.08 asked. The "pink sheet" quote for the
Common Stock on _______________, 1997 was $.___ bid and $.___ asked.


                                       18
<PAGE>


It should be assumed that even with this pink sheet quote, there is an extremely
limited  trading  market - and very  little  liquidity  - for the Dencor  Common
Stock. The trading volume of the Dencor Common Stock in 1996 was 107,500 shares.
81,300 shares of the Dencor Common Stock have traded in the period from November
13, 1996 through July 31, 1997, with all of that trading occurring in July 1997.
There is not any  assurance  that the trading  volume of the Dencor Common Stock
will increase after the Merger.

12.  Penny  Stock   Regulation.   The  SEC  has  adopted   rules  that  regulate
broker-dealer practices in connection with transactions in "penny stocks". Penny
stocks  generally are equity  securities  with a price of less than $5.00 (other
than securities registered on certain national securities exchanges or quoted on
the NASDAQ  system,  provided  that current  price and volume  information  with
respect to  transactions  in such  securities  is  provided  by the  exchange or
system).  The penny stock rules require a broker-dealer,  prior to a transaction
in a penny stock not otherwise  exempt from the rules, to deliver a standardized
risk disclosure  document  prepared by the SEC that provides  information  about
penny  stocks and the nature and level of risks in the penny stock  market.  The
broker-dealer  also  must  provide  the  customer  with  current  bid and  offer
quotations for the penny stock,  the compensation of the  broker-dealer  and its
salesperson in the transaction and monthly account statements showing the market
value of each penny  stock  held in the  customer's  account.  The bid and offer
quotations, and the broker-dealer and salesperson compensation information, must
be given to the  customer  orally or in  writing  before or with the  customer's
confirmation.  In  addition,  the penny  stock  rules  require  that  prior to a
transaction  in a  penny  stock  not  otherwise  exempt  from  such  rules,  the
broker-dealer must make a special written  determination that the penny stock is
a suitable  investment  for the  purchaser and receive the  purchaser's  written
agreement to the transaction.  These disclosure requirements may have the effect
of reducing the level of trading  activity in the  secondary  market for a stock
that becomes  subject to the penny stock rules.  Because the Dencor Common Stock
trades below $5.00 per share and is not traded on the NASDAQ system,  the Dencor
Common Stock is subject to the penny stock rules, and PAI stockholders will find
it difficult to sell the Dencor Common Stock they receive in the Merger.

13. Related Party  Transactions  and Possible  Conflicts of Interest.  As of the
date of this Joint Proxy Statement/Prospectus, the Board of Directors of the PAI
consisted of Charles T. Condy, Christopher, T. Condy and George F. Pilloton, all
of whom are executive  officers and principal  stockholders of PAI. Thus,  there
has been in the past the  potential  for  conflicts  of interest in PAI and such
individuals  or entities in which such  individuals  have an  interest.  PAI has
attempted to ensure that any such  transactions  were entered into on terms that
were no less  favorable  than  could have been  obtained  in  transactions  with
unrelated third parties.

14.  Interest Rate Changes.  PAI,  through  PACC,  its wholly owned  subsidiary,
engages in project finance activities related to the Company's operations.  PACC
invests in projects  for clients of PAI and others with energy  project  finance
needs.  An increase in interest  rates would  increase the relative  cost of the
financing  and  subsequently  could  decrease  the number of project  financings
completed and/or the return on capital.


                                       19
<PAGE>


15. Foreign  Currency Risk. PAI intends to commence  operations in Europe and in
other countries  outside the United States.  PAI expects that it may be paid for
such  projects in the local  currency of the country or  countries  in which the
operations  are  completed.  These  currencies  are not  "pegged"  or in any way
directly related to the U.S. dollar.  Subsequently,  any changes in the exchange
rate between the U.S.  dollar and other  currencies,  or the  restriction by any
government  of the  flow of  currency,  or  inflation  in any of the  currencies
including the U.S. dollar could have a material adverse effect on PAI.

16.  Disclosure   Regarding   Forward-Looking   Statements.   This  Joint  Proxy
Statement/Prospectus includes "forward-looking statements" within the meaning of
Section 27A of the  Securities Act Of 1933, as amended (the  "Securities  Act"),
and  Section  21E of the  Securities  Exchange  Act Of  1934,  as  amended  (the
"Exchange  Act").  All  statements  other than  statements  of  historical  fact
included in this Joint Proxy Statement/Prospectus,  including without limitation
the  statements  under  "RISK  FACTORS",  "DENCOR  MANAGEMENT'S  DISCUSSION  AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" and "PAI MANAGEMENT'S
DISCUSSION AND ANALYSIS OF FINANCIAL  CONDITION AND RESULTS OF OPERATIONS",  are
forward-looking  statements.  Although each of PAI and Dencor  believes that the
expectations reflected in such forward-looking  statements are reasonable,  they
can give no assurance  that such  expectations  will prove to have been correct.
Important factors that could cause actual results to differ materially from each
of  PAI's  and  Dencor's   expectations   are  disclosed  in  this  Joint  Proxy
Statement/Prospectus,  including  without  limitation  in  conjunction  with the
forward-looking  statements  included in this Joint Proxy  Statement/Prospectus.
See "DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS".

                        DENCOR ENERGY COST CONTROLS, INC.

     Dencor was  incorporated on January 16, 1974 under the laws of the State of
Colorado for the purpose of developing,  manufacturing, and marketing electronic
devices.  Currently,  Dencor's  primary  activity is the manufacture and sale of
electrical demand controllers that manage electricity consumed in residences and
commercial establishments and energy control devices used by utilities to modify
residential  energy  use  patterns.  Dencor  has  its  headquarters,  production
facilities, and research and development laboratories in Denver, Colorado.

     Dencor is  engaged in only one  industry,  that of  designing,  developing,
manufacturing,  marketing,  and  installing  products and systems that assist in
controlling  the cost of  energy  utilization.  Management  of  Dencor  does not
recognize any significant  business  difference,  at least at this time, between
sales of residential demand controllers,  special relay equipment for utilities,
temperature   activated  duty  cyclers,   commercial  demand  controllers,   and
interlocks.

                                       21


<PAGE>

     Dencor's  primary business is the assembly and sale of control systems that
reduce  electrical  energy costs. Its principal product is the electrical demand
controller  that  enables a  homeowner  having an electric  heating  system or a
central air  conditioning  system to control the peak use of  electricity.  This
enables the homeowner to achieve cost savings in geographic  locations served by
electric  utilities  that include a demand factor in their  residential  billing
rates.  Demand rates are used by electric  utilities  to encourage  consumers to
reduce their peak usage of electricity.

     A demand  controller  monitors  the total power  consumption  and turns off
selected loads,  typically  heating circuits,  during peak consumption  periods,
restoring them at the end of that period. The controller automatically keeps the
consumption  within the level  selected.  The principal  markets for residential
demand control systems are in regions served by utilities with a demand rate for
residential  customers.  The residential demand controller is designed for homes
heated electrically by baseboard heaters,  radiant heaters, heat pumps, electric
boilers and electric furnaces, and may also be used to control air conditioners.

     The sale of residential demand control systems  contributed 73% of Dencor's
total sales during 1996.

     Dencor has developed demand controllers for commercial buildings. One model
of the commercial  systems  includes a graphics  system to interface  commercial
demand controllers to IBM compatible computers. This graphics system can display
minute-by-minute  demand data as well as 15-minute,  daily,  monthly, and annual
summaries.  All data is also stored on computer disk for later  inspection.  The
sale of commercial  demand  control  systems  contributed  16% of Dencor's total
Company sales during 1996.

     Dencor has developed a series of products  used to control  water  heaters,
space heaters, and air conditioners for specific utility applications.  Sales of
these  products  accounted  for 11% of net sales in 1996.  Dencor  anticipates a
gradual growth in this portion of the business.

     Dencor's  demand  control  systems are  currently  being  marketed  through
traditional electrical  distribution channels. They are being sold to electrical
distributors  who, in turn,  market and  distribute  these systems to electrical
contractors  who provide  installation  services to the builder or the consumer.
Dencor  also sells to dealers  who  specialize  in selling  energy  products  to
customers  and also  utilizes  manufacturer's  representatives  to  promote  the
distribution  of its  products.  Dencor  also sells to  organizations  that have
lease/purchase  plans with customers.  This enables the customer to realize cost
savings which usually approximate or exceed the lease payments.

     Dencor's foreign sales in 1996 were less than 1% of total sales.

     During  1996,   Dencor   developed  a  new  series  of  commercial   demand
controllers.  These  controllers  are designed to permit demand  monitoring  and
controller parameter changes from a remote location by use of a modem. These new
products are in production.

     Competition  is intense in the energy  management  control  system  market.
Dencor competes directly with several  relatively small electronic  companies in
its  residential   controller  market,  and  with  the  major  manufacturers  of
electrical controls for its commercial demand controllers.

     Several  companies  manufacture  systems  which are  similar  in concept to
Dencor's  demand  controllers.  Many of the companies with which Dencor competes
and will be  competing  in both  the  residential  and  commercial  market  have
substantially  greater financial and technical  capabilities.  Products of these
companies  often  compete  directly  with those being offered by Dencor and with
those currently in development.

     Dencor  has   approximately   16   suppliers   for  its   components.   Its
semi-conductor  components  are  made by a  variety  of  primary  semi-conductor
manufacturers.  Dencor also has components  made to order from several local and
national vendors.  It is believed that adequate sources are available and Dencor
has had no significant difficulty in obtaining components. Dencor believes other
alternate sources are available if required. The principal suppliers are: Circle
AW, Deltrol, Star Circuits, and X-10 USA.

     Dencor's suppliers'  productive capacities are believed to be sufficient to
meet any rapid delivery requirements of customers or to any continuous allotment
of goods.

     During 1996, two major  customers  accounted for 44% of Dencor's net sales.
These  customers  are not  affiliated  with  Dencor.  The  loss of any of  these
customers may adversely affect Dencor's business.

     As of March 31,  1997,  Dencor  had a backlog  of orders  totaling  $56,649
consisting of equipment orders from  distributors.  Dencor  anticipates  filling
these orders during the current year.

     Most of Dencor's  demand control  systems are not protected by any patents.
While  management  believes  that patent  protection  may be  desirable  in some
instances,  it does not  consider  such  protection  essential  to the  ultimate
success  of  Dencor.  A patent  was  issued  to  Dencor  on April 4,  1989 for a
Variable-Limit Demand Controller for metering electrical energy. In 1991, Dencor
entered into a non-exclusive  licensing  agreement with an unrelated third party
for use of Dencor's patent. A patent  application was filed in April 1994 for an
Adaptive Load Cycler for Controlled Reduction of Energy Use; however, Dencor has
no assurance a patent will be issued.

     In the fiscal  years  ended  December  31, 1996 and 1995,  Dencor  expended
$69,700 and $73,900,  respectively, on Dencor sponsored research and development
activities.  Dencor plans to continue research and development activities during
1997.

     Dencor's  compliance  with  federal,  state and local laws and  regulations
relating to the discharge of material into the environment or otherwise relating
to the protection of the environment does not have a material impact on Dencor's
capital expenditures.

     On July 31, 1997, Dencor had five full-time employees.  Two were engaged in
administration,   two  in  production,  and  one  in  engineering  research  and
development.

     Dencor leases 3400 sq. ft. of manufacturing space on a month to month basis
for  $1,687  per month  and 1700 sq.  ft. of sales,  office,  and  research  and
development  space  pursuant  to a lease for $995 per month  pursuant to a lease
expiring  on May 14,  1998 at 1450  West  Evans,  Denver,  Colorado.  Management
considers these facilities to be adequate for its requirements for the immediate
future.

            DENCOR MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

Liquidity and Capital Resources

     The independent  auditors' report on Dencor's financial  statements for the
year ended December 31, 1996, included a "going concern" explanatory  paragraph,
which means that the auditors have  expressed  substantial  doubt about Dencor's
ability  to  continue  as a going  concern.  Management  plans in  regard to the
factors  which  prompted the  explanatory  paragraph  are discussed in Note 2 to
Dencor's December 31, 1996 financial statements.

     Dencor considers,  and currently uses for internal management  purposes,  a
number of measures of liquidity.  These measures include the Current Ratio which
is the ratio of current assets to current  liabilities  and the Sales to Working
Capital Ratio. Working capital is Current Assets less Current Liabilities.


                                    1996             1995              1994

<PAGE>


     The major  factors  affecting  these ratios were the net income in 1995 and
the net losses for 1996 and 1994.  Dencor has made  extensive  use of short-term
debt as summarized in the following table:

</TABLE>


     The  weighted  average  interest  rate  during  the period was based on the
outstanding  balance and interest rate at each  month-end for each note.  Dencor
anticipates  continuing  short term borrowing in 1997.  Dencor  currently has no
line of credit.  If working  capital  beyond that provided by profits is needed,
additional debt financing will be sought.  If traditional  debt financing is not
available,  Dencor will attempt to raise  working  capital by private  borrowing
including  stockholder  loans,  or  sales of stock  through  private  placements
although no assurances can be given that financing will be available.  Dencor at
present has no long-term debt.

     The Merger  Agreement  with PAI  provides  that PAI will cause  $200,000 of
working  capital to be provided to Dencor.  If the Merger is consummated and the
$200,000  is  provided  to Dencor,  these  funds will be utilized to further the
activities  previously  undertaken by Dencor under a division to be known as the
Denver  Division  while  Dencor  and PAI  pursue  other  business  opportunities
including  those  undertaken  by PAI prior to the Merger.  In  addition,  Dencor
believes  that as a result of the  Merger,  Dencor will be better able to obtain
financing for the activities of the Dencor Division because of the combined size
of Dencor and PAI and because of the  expertise of obtaining  financing of PAI's
PACC subsidiary.  However,  there is no assurance that such additional financing
will be available on terms satisfactory to Dencor.

Results of Operations

     Quarter Ended March 31, 1997 Compared To Quarter Ended March 31, 1996

     Sales. Sales of $113,100 in the first quarter of 1997 were approximately 9%
greater  than the  $103,700  in sales for the  comparable  period  in 1996.  The
increase is primarily a result of an increase in sales to dealers.

     Cost And  Expense.  Cost of  products  sold as a  percentage  of net  sales
decreased  8.4% for the first  quarter of 1997  compared  to the same  period in
1996.  The  increase  in  gross  margin  is  primarily  due an  increase  in the
percentage of sales to dealers  because dealers sales have a greater margin than
sales to utilities.


                                       25

<PAGE>


     Selling  Expenses.  Selling expenses as a percentage of net sales increased
1% during the first quarter of 1997  compared to the first quarter of 1996.  The
increase is primarily due to increased travel expenses.

     General And Administrative  Expenses.  General and administrative  expenses
were  essentially  the same in each of the first  quarter  of 1997 and the first
quarter of 1996.

     Research And Development. Research and development expenses as a percentage
of net sales decreased  slightly in the quarter ended March 31, 1997 as compared
to the same quarter of 1996.

     Earnings.  Dencor's  net  loss for the  first  quarter  of 1997 was  $1,500
compared  to a loss of  $11,700  for the same  period  in the  prior  year.  The
decrease in losses was due to the decrease in cost of goods sold as a percentage
of sales.

     Year Ended December 31, 1996 Compared To Year Ended December 31, 1995.

     Sales.  Dencor's  sales in 1996 of $388,700  were 32 percent  lower than in
1995 net sales of $567,900.  Approximately  49% of the sales decrease was due to
international  sales  declines.  Dealer  sales also  experienced  a decrease  of
approximately  27%. The net loss for 1996 was $74,400  compared to net income of
$11,300 in the prior year.

     Gross  Margins.  The gross margin  percentages  were 46%,  46%, and 44%, of
sales for 1996, 1995, and 1994 respectively.

     Selling  Expenses.  Selling  expenses as a percentage of sales increased to
5.6% in 1996 compared to 3.5% in 1995. The primary reasons for the increase were
an increase in trade show attendance and travel and a 32% decrease in net sales.

     General and Administrative Expense.  General and administrative expenses as
a percentage of sales have  increased to 37.7% in 1996 compared to 25.6% in 1995
primarily due to a 32% decrease in net sales.

     Research and  Development.  Research  and  development  expenses  decreased
slightly in 1996 due to a decrease in activity.

     Inflation. Inflation has no significant impact on the operations of Dencor.

     Management's  Plans.   Dencor's  1997  operating  plan  includes  achieving
increased  sales goals and  continuing its cost  reduction  program.  Management
believes that actions  presently  being taken to revise  Dencor's  operating and
financial  requirements  will  enable  Dencor to achieve  profitable  operations
during 1997.

                            PROVEN ALTERNATIVES, INC.

The Company

     PAI  was  incorporated  in  April  1991  under  the  laws of the  State  of
California and was  subsequently  reincorporated  under the laws of the State of
Delaware in November  1991.  In July 1991,  PAI acquired 85% of the  outstanding
capital stock of Golden Bear Cogen,  Inc.  ("Golden  Bear");  in August 1996 PAI
acquired the remaining 15% of the  outstanding  capital stock of Golden Bear. In
April 1992 PAI acquired 100% of Luminae, Inc.  ("Luminae").  Luminae is a wholly
owned operating subsidiary of PAI, concentrating in specialized lighting design.
Proven Alternatives  Capital  Corporation  ("PACC") was incorporated as a wholly
owned  subsidiary  of PAI and is intended  to develop  investment  vehicles  and
provide related services for sophisticated  institutional  investors in order to
provide  project  financing for PAI. In February 1992, PAI acquired Puget Energy
Services,  Inc.  ("PESI"),  a company  specializing  in the  execution of energy
efficiency  projects under utility contracts.  Subsequently,  in March 1994, PAI
merged PESI into PACC.

     PAI is an  integrated  and  process  energy  management  firm.  It provides
process   knowledge,   energy   management   capabilities,   energy   efficiency
technologies  and capital  capabilities to solve business  problems  relating to
energy  usage.  PAI  provides its  services in six service  areas:  total energy
management,  strategic consulting,  program management, capital services, energy
procurement and energy information  management.  Typically services are provided
by PAI as a long-term  partner  with the customer  and on a  performance  basis.
PAI's services include the identification of under-performing  corporate assets,
the recommendation for and application of processes, equipment and techniques to
improve the  performance of these assets and  investment in these  applications.
PAI markets its  services to companies  that could  benefit  significantly  from
improvements in energy management, energy procurement and use and to those whose
operations are energy and process  intensive.  These clients are located both in
the United States and abroad.

     The electric power industry is currently  undergoing  significant  changes.
From  a  heavily  regulated,   vertically  integrated  and  highly  bureaucratic
industry, it is rapidly transforming into a disaggregated tangle of services and
providers,  each facing significant competitive pressures.  PAI believes that as
deregulation  of  the  U.S.   electrical   industry  unfolds,   it  will  create
opportunities for companies with the capabilities of PAI.

     PAI has historically  marketed its services through a direct sales force to
manufacturing,  commercial,  and industrial  companies on a site-specific basis.
Starting in 1993,  PAI moved from project by project  orientation to a long-term


                                       27

<PAGE>


service a relationship  basis, and began marketing its services to organizations
on  a  company-wide   basis.   PAI's  clients  include  Champion   International
Corporation, Kaiser Permanente,  International Paper Company and other companies
in the pulp & paper  industry,  health care and real estate  industries.  PAI is
compensated  for  its  services  through   professional   service  fees,  energy
application  sales,  capital  revenues and management fees. These fees are often
performance  based,  such that the amount  earned by PAI is  dependent  upon the
success of the programs designed and implemented by PAI.

PAI Offices

     PAI's offices are located at 1740 Army Street,  San  Francisco,  California
94124 and its telephone number is (415) 285-0800.

Business

     General

     PAI is an integrated energy management firm. It provides process knowledge,
energy  management  capabilities,  energy  efficiency  technologies  and capital
capabilities to solve business  problems  relating to energy usage. PAI provides
its  services  in  six  service  areas:  Total  Energy   Management,   Strategic
Consulting, Program Management, Capital Services, Energy Procurement, and Energy
Information  Management.  Typically,  service  programs are provided by PAI as a
long-term partner with the customer and on a performance  basis.  PAI's services
include  the   identification  of   under-performing   corporate   assets,   the
recommendation and application of processes, equipment and techniques to improve
the  performance of these assets and investment in these  programs.  PAI markets
its services to companies which could benefit significantly from improvements in
energy  procurement and use and to those whose operations are  energy-intensive.
These clients are located both in the United States and abroad.

     Total Energy Management

     Total Energy  Management  encompasses  PAI's  varied  services and has been
created as an  opportunity  to become  customers'  single  outsource  for energy
management. The four parts of Total Energy Management are:

     Energy Management Business Strategy - consists of defining and prioritizing
     a customer's  energy needs and  developing  an agreement  through which PAI
     begins the relationship.

     Implementation  - consists of implementing  the  comprehensive  initiatives
     identified in the Energy Management  Business  Strategy,  which may include
     the energy information  management  service,  procurement,  capital program
     design, construction,  operational and maintenance management improvements,
     performance monitoring and control systems and other services.


                                       28

<PAGE>
        

     Capital Investment - consists of structuring  customized capital facilities
     that are provided to the program at hand,  typically  through  non-recourse
     instruments.

     Performance  Management  -  consists  of  managing  energy use and cost and
     enhancing  energy   performance   including  ongoing  data  management  and
     performance  monitoring,  energy procurement  optimization,  and continuous
     improvement to operations and maintenance.

     Strategic Consulting

     PAI  provides   strategic   management   consulting   services   including:
benchmarking   energy  policy,   standards  and  practices;   developing  energy
performance  improvement goals and objectives and creating  business  strategies
and tactics to achieve those goals;  assisting with design of new facilities and
due-diligence on facility  acquisition;  assessing  energy supply  alternatives,
negotiating  advantageously priced supply contracts;  and managing relationships
with energy  suppliers.  PAI educates,  trains and builds  energy  awareness for
clients,  evaluates and monitors  program results and customer  satisfaction and
advocates  on behalf of  customers  with  regulators,  legislators  and  opinion
leaders.  This  consulting  is  performed  largely  under  Professional  Service
Agreements,  where PAI is  compensated  on a value basis  largely in the form of
fees.  Strategic Consulting is often the first step in a Total Energy Management
solution.

     Program Management

     PAI works with  customers to create and  implement  custom,  comprehensive,
performance  based  programs  designed to achieve  specific  cost  reduction and
productivity  improvement  objectives,  such as reducing supply costs,  reducing
energy demand and consumption,  including energy cost per unit output,  reducing
operations and maintenance  costs of energy  equipment and systems and improving
product  quality and  through-put  and  increasing  process  flexibility.  PAI's
compensation  is often based upon the savings  due to the  program's  successful
implementation.

     Capital Services

     Through PACC, PAI provides capital investment options for its clients. PACC
assesses  capital  investment  options,  assists  in the  selection  of  options
available,  and invests,  primarily on a performance basis, in customers' energy
performance improvements.  PACC's performance investments are usually structured
to accelerate or avoid existing  capital budget processes which limit customers'
investment capabilities. PACC tailors capital management processes that expedite
necessary   investments,   and  creates  customized  capital  programs  to  meet
individual customer needs. PACC has financed,  on a non-recourse basis,  certain
long term energy savings contracts owned by PACC with Energy Capital Partners


                                       29

<PAGE>


L.P., Inc., of Boston, Massachusetts,  at rates varying from 11.25% to 16.8%. As
of  February  28,  1997 there was  $4,983,370  of senior  debt  outstanding  and
$3,352,130 of subordinated  debt  outstanding  with respect to these  contracts.
PACC may continue  financing  contracts with Energy Capital  Partners so long as
the terms are acceptable. There can be no assurance that Energy Capital Partners
will continue to offer acceptable terms and rates in the future.

     Energy Supply Management

     PAI offers energy supply  services,  wherein PAI represents  clients in the
procurement of power,  natural gas and other forms of energy supply. In addition
to  developing  databases  on  electricity  and natural gas  suppliers,  PAI has
developed an energy  procurement  analysis tool that  quantitatively  integrates
customers' energy requirements,  such as reliability,  quality,  price, service,
environmental  impacts,  risk and other factors. PAI believes that the impending
deregulation  of the electric  industry  will create a greater  demand for PAI's
energy supply  services,  as companies,  which to this point have not focused on
their energy usage,  are forced to choose among competing energy  suppliers.  In
attempts to decrease  their utility  expenditure,  such  companies may employ an
energy  management  firm  such  as PAI  rather  than  create  their  own  energy
management   organization.   However,  there  can  be  no  assurance  that  such
deregulation will actually increase the demand for PAI's services.

     Energy Information Management Services

     PAI is developing energy accounting  capabilities  through the installation
of on-site meter reading  equipment,  which will allow  multi-site  customers to
gain knowledge about their true energy use and habits. The information collected
will be transferred  to a central  station via an internet user  interface.  The
system will track real time energy use, will provide  up-to-date  information on
load profiles and energy use  practices  and will help predict  future usage and
costs.  The system will also identify  energy  infrastructure  improvements  and
measure their performance.  PAI believes that in a deregulated  electric market,
precise   knowledge  of  usage  habits  will  be  central  to  intelligent   and
cost-effective purchasing. This aspect of PAI's business is in the developmental
stages.

Luminae Souter Lighting Design

     Luminae,  Inc.,  d.b.a.  Luminae Souter Lighting Design, is a subsidiary of
PAI and is one of the nation's premier architectural lighting firms. Luminae has
a staff  of  lighting  engineers,  architects  and  interior  designers  and has
implemented  hundreds of architectural  projects throughout the U.S. and abroad.
Luminae's  work  includes a wide range of project  types,  including  industrial
facilities,  hotels,  resorts,  restaurants,  airports,  sports arenas, offices,
research  facilities,  schools and others.  Luminae has been  honored  with more
lighting  design  awards over the past six years than any other such firm in the
country,  including  numerous Edison Awards of Excellence and ASID, HALO and IES
design awards. In 1990-1991,  Luminae received the three most prestigious design
awards given in the lighting design industry.

Deregulation Of The Electric Utility Industry

     The $400 billion per year electric power  industry is currently  undergoing
significant changes. From a heavily regulated,  vertically integrated and highly
bureaucratic industry, it is rapidly transforming into a disaggregated tangle of
services  and  providers,   each  facing  significant   competitive   pressures.
Management of PAI believes that,  within a few years,  the industry is likely to
be comprised of the following principal components:

     Generating  companies that own and operate power plants and sell power into
          a competitive wholesale market.

     Transmission  companies that own and maintain (but do not operate) the high
          voltage transmission system that allows bulk power transfer.

          from  consulting,  information  management and engineering to finance,
          program  management,  operations and maintenance,  purchase management
          and bill consolidation and payment.

     PAI believes that the completion of the Merger will  strengthen its ability
to compete in this environment.

Certain PAI Litigation

     In  1996,  PAI  settled  a  lawsuit   involving  several  of  the  minority
shareholders of Golden Bear. Under the terms of the settlement, PAI acquired the
remaining 15% minority shares and agreed to pay therefor  approximately $400,000
to such minority shareholders in monthly installments over two years.

     In late  1996,  in an  arbitration  filed  by the  owner of  certain  micro
cogeneration  patents then  licensed to PAI,  PAI became  subject to an award in
favor of that owner in an amount in excess of  $1,100,000.  PAI has  executed an
Agreement To Satisfy  Judgment And Refrain From  Execution On Judgment  with the
owner under the terms of which PAI will pay the judgment  over a period of three
years and the owner  will  refrain  from any  collection  efforts so long as the
payments are made when due.

              PAI MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

     The following  discussion and analysis  should be read in conjunction  with
the Financial Statements and the notes thereto contained herein. This Memorandum
contains  forward-looking  statements related to business development  prospects
which involve risks and uncertainties. The Company's actual results could differ
materially  from those  anticipated  in these  forward  looking  statements as a
result of  certain  factors,  including  marketing  risks and those set forth in
"RISK FACTORS" and elsewhere in this Joint Proxy Statement/Prospectus.


General

     PAI and Dencor  have,  subject to  obtaining  approval of their  respective
shareholders'  agreed on a plan of merger  which  provides for the merger of PAI
with and into Dencor  Acquisition  Corporation,  a  wholly-owned  subsidiary  of
Dencor Energy Cost  Controls,  Inc, which will result in PAI being the surviving
corporation and a wholly owned subsidiary of Dencor.

     The following  discussion and analysis  relates to the financial  condition
and results of operations of PAI for the two years ended  December 31, 1996. PAI
has  sustained  losses  since its  inception in 1991.  Management's  decision to
reengineer  the  marketing  direction  of PAI toward  large  programs and energy
management rather than single projects was a significant  contributing factor to
such losses.  Management  recognized  that this  reengineering  would  adversely


                                       32

<PAGE>


affect  results in the  near-term  and  believes the shift in marketing of PAI's
programs and processes is now leading to the development of long-term  strategic
relationships  that are  beginning  to take  shape in 1997 and are  expected  to
continue into 1998. While the fundamental  services and technologies  offered by
PAI have  remained  largely the same,  the  emphasis on programs (as compared to
one-off projects),  on production enhancements within the industrial sector, and
the  integration  of services  into  customer  solutions is now seen as the most
effective  manner to develop  meaningful  core  business.  For  example,  PAI is
developing a potential $200 million pulp & paper relationship,  to commence with
a $50 million  first  phase.  Additionally,  in June 1997,  PAI entered into its
first   national   energy   management   agreement   wherein  PAI  will  deliver
comprehensive  energy  management  services  on a  corporate-wide  basis to this
billion-dollar revenue customer for five years.  Throughout this period, PAI has
funded its operations through  non-recourse  financing of long term receivables.
PAI expects to raise capital in the future through  additional project financing
as well as the  sale  of its  preferred  stock.  Management  expects  to use the
proceeds  from any future  stock  offering  to provide  working  capital for the
expansion of the business.

Liquidity And Capital Resources

     The independent auditors' report on PAI's consolidated financial statements
for the years  ended  December  31,  1996 and 1995,  included a "going  concern"
explanatory  paragraph which means that the auditors have expressed  substantial
doubt about PAI's ability to continue as a going  concern.  Management  plans to
address  liquidity  and  capital  resources  are  discussed  in Note 1 to  PAI's
December 31, 1996 consolidated financial statements.

     At December 31, 1996 PAI had shareholders'  deficit of $9,281,562 comprised
of common stock and common stock option equity of  $16,225,825  and  accumulated
deficit of  $25,507,387.  Also, at December 31, 1996,  PAI had negative  working
capital of $697,676  compared  to  negative  working  capital of  $4,252,998  at
December  31,  1995.  During  1995 and  1996,  operations  were  supported  by a
$3,000,000  bank line provided by US Bank of Washington  that allowed cash draws
as well as letters of credit.  The balance owed US Bank at December 31, 1996 and
December 31, 1995 was $2,813,229 and $2,744,640,  respectively. PAI, through its
investment  subsidiary,  PACC,  refinanced certain long term investments,  which
generated additional working capital in 1996.

     In March 1997,  the US Bank line was replaced by a working  capital line of
$4,000,000  provided  by Silicon  Valley  Bank of Santa  Clara,  California,  to
provide working  capital and letters of credit.  The initial use of the facility
was to  repay  the  outstanding  indebtedness  owed  to US  Bank.  Both  banking
arrangements  were  secured by the pledge of 160,000  shares of common  stock of
California  Energy Company by Charles T. Condy as well as Mr.  Condy's  personal
guarantee. See below, "CERTAIN PAI RELATIONSHIPS AND PAI RELATED TRANSACTIONS".

     At March 31, 1997 negative  working  capital was  $2,310,500 as compared to
$697,676 at December 31, 1996 and $1,455,600 at March 31, 1996.

     PAI anticipates  meeting liquidity needs through growth in the business and
non-recourse  financings  of long-term  receivables.  Management  estimates  the
economic  value  of  PAI's  long-term  receivables  may  exceed  book  value  by
approximately  $6.9 million as of December 31, 1996.  This  estimate is based on
the  average  billings in 1996,  assuming  such  levels of  performance  will be
sustained for the remaining term of the project and using a 16% discounted rate.
However,  there is no  assurance  that PAI  managment's  belief  concerning  the
estimates of economic  value of the energy  savings  receivables  is accurate or
will actually be realized due to credit and performance risks.

     PAI  anticipates  meeting  capital  resource  needs  achieving   profitable
operations  and raising  preferred and common  equity.  PAI has been involved in
discussions with potential sources of financing for PAI. It is anticipated that,
following the Merger, PAI and Dencor will pursue additional  financing through a
private placement or public offering of preferred stock,  common stock, or other
equity securities.  Any such offering will result in further dilution to PAI and
Dencor  shareholders.  There is no assurance that PAI and/or Dencor will be able
to  obtain  equity  financing  following  the  Merger or that it will be able to
obtain such  financing on terms that are favorable to the combined  entities and
their shareholders.


Results Of Operations

The Twelve Months Ended December 31, 1996 As Compared To The Twelve Months Ended
December 31, 1995

     Gross  revenues  for  the  twelve  months  ended  December  31,  1996  were
$9,763,278 as compared to  $21,397,419  for the twelve months ended December 31,
1995. The decrease of 54% is attributable to several elements.  First, PAI spent
the second half of 1995 negotiating two comprehensive  equity investments in PAI
that included substantial joint venture opportunities for PAI and the investors.
In both cases,  PAI believed  its  marketing  and sale  efforts  would have been
significantly  enhanced  by and with new  partners.  Both  investors  ultimately
declined to invest due to an inability to obtain a controlling  interest in PAI.
Despite the absence of additional working capital and the contemplated strategic
partnerships,  PAI  management  made the  decision  to  continue  to  shift  its
marketing strategy to larger customers that offered PAI long-term  relationships
and   multiple   contract   opportunities.   In  addition,   PAI's   traditional
utility-based,  project  oriented  method of selling  was ended due to less than
desired  margins  and a lack of  utility  focus  due to the  impending  electric
utility industry deregulation.

     This strategy involves targeting large industrial and commercial  customers
in  industries  wherein PAI has  established a strong track record of delivering
services  on  time  that  increase   customer   profitability   through  process
improvement as well as energy savings.  PAI believes that future revenue will be
enhanced by the redirection of the marketing plan in 1996.

     Revenue for 1996 reflects  lower sales of projects,  but increased  revenue
from PACC in total dollars and as a percent of total revenue. PACC revenues grew
72% in 1996,  to  $5,448,510  from  $3,160,616  in  1995,  and were 56% of total
revenues in 1996 compared to 15% in 1995. PACC revenues  represent the financing
of long term project cash flows that will continue for the most part until 2002.

     Gross  profit  in 1996  grew to  $6,104,297  from  $4,220,734  in 1995,  an
increase  of 45%.  This  increase  is  largely  explained  by the growth of PACC
revenues.

     Selling, general and administrative expenses were $5,624,998 and $5,502,908
for  the  twelve   months  ended   December  31,  1996  and  December  31,  1995
respectively.  As a result of lowered sales volume in 1996, PAI was less able to
charge payroll and overhead expenses to projects,  resulting in a 2% increase in
SG&A.  PAI's cost base  (defined by management as SG&A plus payroll and overhead
charged  to cost of goods  sold)  declined  from  $6.5  million  in 1995 to $5.9
million in 1996.


                                       34

<PAGE>

     Long-term debt interest expense decreased from $701,143 in 1995 to $526,722
in 1996; this expense related to accrued  interest on indebtedness of PAI on its
working  capital  line  with  U.S.  Bank of  Washington  and on a note to  Puget
Western,  Inc.  related  to the  acquisition  of  Puget  Energy  Services,  Inc.
Non-recourse interest expense increased from $1,598,527 in 1995 to $3,314,516 in
1996.  Non-recourse  debt  increased  $3,606,917 to  $25,574,125 at December 31,
1996; non-recourse debt increased $15,290,067 from December 31, 1994.

     PAI incurred a net loss of $4,549,794  for the year ended December 31, 1996
compared to a net loss of $4,122,605 for the year ended December 31, 1995.

The Three  Months  Ended March 31, 1997 As  Compared To The Three  Months  Ended
March 31, 1996

     At March 31, 1997 net sales were $1,705,400 compared to $1,233,700 at March
31, 1996. Net loss from  continuing  operations was $1,065,000 at March 31, 1997
compared to $923,000 at March 31, 1996.

                        POST-MERGER PROFILE AND STRATEGY

     It is anticipated that after the consummation of the Merger, each of Dencor
and PAI will continue  their  respective  businesses in the ordinary  course and
consistent  with past  practice  with Dencor's  activities  being  undertaken by
Dencor or a separate division to be known as the Dencor Division.  While each of
the businesses of Dencor and PAI will operate separately after the Merger, it is
anticipated that the business  activities of each will be coordinated to benefit
both companies.  Management of Dencor believes that Dencor will benefit from the
Merger  because,  among other things,  (i) the business  operations  PAI provide
potential use of an established  market for Dencor products,  (ii) PAI possesses
marketing and  distribution  personnel and expertise  that Dencor  believes will
assist in the  marketing  of Dencor  products,  and  (iii)  Proven  Alternatives
Capital Corporation,  a wholly owned subsidiary of PAI which develops investment
vehicles  and provides  related  services for  sophisticated  and  institutional
investors  to provide  project  financing  for PAI,  potentially  could  provide
financing for the  manufacture  of Dencor  products.  Management of PAI believes
that PAI will benefit from the Merger  because,  among other things,  (i) Dencor
possesses expertise in the development and manufacturing of products and systems
that assist in controlling the cost of energy  utilization  that would be useful
for energy cost  control  programs  implemented  for PAI's  customers,  and (ii)
Dencor is a publicly  held company and as a publicly  held  company  potentially
could obtain additional  capital in the public markets for PAI's operations,  of
which  there is no  assurance.  It is  expected  that the  compatibility  of the
respective  businesses of Dencor and PAI will enable both companies to expand in
a single strategic move.

     PAI has been involved in discussions  with  potential  sources of financing
for PAI. It is  anticipated  that,  following  the  Merger,  PAI and Dencor will
pursue  additional  financing  through a private placement or public offering of
preferred  stock,  common stock, or other equity  securities.  Any such offering
will  result in further  dilution  to PAI and Dencor  shareholders.  There is no
assurance  that  PAI  and/or  Dencor  will be able to  obtain  equity  financing
following  the Merger or that it will be able to obtain such  financing on terms
that are favorable to the combined entities and their shareholders.

Voting of Proxies

     Shares  represented by all properly  executed  proxies received in time for
the  Special  Meetings  and which  have not been  revoked  will be voted at such
meetings in the manner  specified by the holders  thereof.  Proxies which do not
contain an  instruction  to vote for or against or to abstain  from  voting on a
particular matter described in the proxy will be voted in favor of such matter.

     It is not expected that any matter other than those referred to herein will
be brought before either of the Special Meetings. If, however, other matters are
properly  presented,  the persons named as proxies will vote in accordance  with
their  judgment  with  respect to such  matters,  unless  authority  to do so is
withheld in the proxy.

Revocability of Proxies

     The grant of a proxy on the  enclosed  Dencor or PAI form of proxy does not
preclude a stockholder  from voting in person.  A stockholder may revoke a proxy
at any time prior to its exercise by submitting a later dated proxy with respect

Dencor shareholder) or the Secretary of PAI (in the case of a PAI stockholder) a
duly executed revocation,  or by voting in person at the meeting.  Attendance at
the relevant  Special Meeting will not in and of itself  constitute a revocation
of a proxy.

Dissenting PAI Stockholders Rights Of Appraisal

     The DGCL  provides that a stockholder  of a  constituent  corporation  in a
merger has the right to  dissent  and  obtain  payment  for his or her shares in
connection with the merger.

     Therefore, because PAI is a constituent corporation in the Merger, PAI will
pay any dissenting PAI  stockholder the "fair value" of his or her shares of PAI
Common Stock if that stockholder fully complies with the procedures described in
this paragraph.  A PAI stockholder who wishes to dissent must do so with respect
to all of his or her shares of PAI Common  Stock.  If the Merger is  approved by
the stockholders of PAI, and if the Merger is consummated, the DGCL requires PAI
to pay any dissenting PAI stockholder the fair value of his or her shares of PAI
Common Stock if certain  requirements  set forth in the DGCL are satisfied:  (a)
each PAI stockholder electing to demand the appraisal of his or her shares shall
deliver to PAI,  before the taking of the vote on the Merger,  a written  demand
for appraisal of his or her shares; (b) the stockholder may not vote in favor of
or consent to the Merger at the PAI Special  Meeting;  (c) within 120 days after
the effective  date of the Merger,  the  stockholder  may file a petition in the
Court of  Chancery  demanding a  determination  of the value of the stock of all
such  dissenting  stockholders;  (d) upon the filing of any such  petition  by a
stockholder,  service  of a copy  thereof  shall  be  made  upon  the  Surviving
Corporation, which shall within 20 days after such service file in the office of
the  Registrar  and Chancery in which the  petition was filed and duly  verified
list  containing the names and addresses of all  stockholders  who have demanded
payment  for  their  shares  and with whom  agreements  as to the value of their
shares have not been reached by the Surviving Corporation; (e) at the hearing on
such petition,  the Court of Chancery shall determine the  stockholders who have
complied with the appraisal rights  requirements and who have become entitled to
appraisal  rights;  (f) the Court of Chancery may require the  stockholders  who
have  demanded an appraisal for their shares and who hold stock  represented  by
certificates to submit their certificates of stock to the Registrar and Chancery
for notation  thereon of the pendency of the appraisal  proceedings,  and if any
stockholder  fails to comply  with such  direction,  the Court of  Chancery  may
dismiss  the  proceedings  as to such  stockholder;  (g) after  determining  the
stockholders entitled to an appraisal,  the Court of Chancery shall appraise the
shares,  determining  their fair value exclusive of any element of value arising
from the accomplishment or expectation of the Merger,  together with a fair rate


                                       40

<PAGE>


of interest, if any, to be paid upon the amount determined to be the fair value;
(h) upon application of the Surviving Corporation or by any stockholder entitled
to  participate in the appraisal  proceeding,  the Court of Chancery may, in its
discretion,  permit  discovery or other pretrial  proceedings and may proceed to
trial upon the appraisal  prior to the final  determination  of the  stockholder
entitled to an appraisal;  (i) the Court of Chancery shall direct the payment of
the fair value of the shares,  together with interest,  if any, by the Surviving
Corporation to the stockholders entitled thereto; (j) the cost of the proceeding
may be  determined  by the Court of  Chancery  and taxed upon the parties as the
Court of Chancery deems equitable in the circumstances; and (k) upon application
of a  stockholder,  the Court of  Chancery  may  order  all or a portion  of the
expenses   incurred  by  any   stockholder  in  connection  with  the  appraisal
proceeding,  including,  without limitation,  reasonably attorneys' fees and the
fees and  expenses of experts,  to be charged pro rata  against the value of all
the shares entitled to an appraisal. A PAI stockholder will not waive his or her
dissenter's  rights by abstaining from the vote on the Merger at the PAI Special
Meeting;  however, a PAI stockholder will waive his or her dissenter's rights if
he or she votes in favor of or consents to the Merger. Therefore, in order for a
PAI stockholder to exercise his or her dissenter's rights in connection with the
Merger, he or she must comply with the requirements outlined above.

     From and after the effective  date of the Merger,  no  stockholder  who has
demanded his or her  appraisal  rights shall be entitled to vote such PAI Common
Stock for any purpose or to receive payment of dividends or other  distributions
on the PAI  Common  Stock  (except  dividends  or  distributions  payable to PAI
stockholders  of record at a date  which is prior to the  effective  date of the
Merger). If no petition for an appraisal shall be filed within the required time
period, then the right of such PAI stockholder to an appraisal shall cease.

     Dencor's management has concluded that, because Dencor is not a constituent
corporation  in the  Merger,  the  shareholders  of Dencor are not  entitled  to
dissent  and  require  Dencor  to pay the fair  value of their  shares of Dencor
Common Stock in connection with the Merger.  However, it is possible that one or
more shareholders of Dencor may challenge the denial of dissenters rights to the
shareholders of Dencor,  and such a challenge could result in litigation between
Dencor and the challenging shareholders.

     See Appendix II of this Joint Proxy  Statement/Prospectus for a copy of the
provisions of the Delaware General Corporation Law concerning dissenters' rights
of appraisal.

     Dencor has the right to  terminate  the Merger  Agreement if any holders of
PAI Common Stock exercise dissenters' rights of appraisal.

Solicitation of Proxies

     Subject to the Merger Agreement,  each of Dencor and PAI will bear the cost
of the  solicitation of proxies from the holders of their  respective  shares of
common  stock,  except that PAI will bear the cost of printing  and mailing this
Joint Proxy Statement/Prospectus. However, if the Merger is not consummated, PAI
will reimburse Dencor for the solicitation of proxies from its shareholders.  In
addition to solicitation by mail, the directors,  officers and employees of each
corporation and its subsidiaries  may solicit proxies from  stockholders of such
corporation by telephone or telegram or in person. Such directors,  officers and
employees will not be additionally compensated for such solicitation but may be



                                       41

<PAGE>


reimbursed for out-of-pocket expenses in connection therewith. Arrangements will
also  be  made  with  brokerage  houses  and  other  custodians,   nominees  and
fiduciaries for the forwarding of solicitation material to the beneficial owners
of shares held of record by such persons, and Dencor and PAI will reimburse such
custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses
in connection therewith.

     HOLDERS OF DENCOR  COMMON  STOCK AND PAI COMMON STOCK SHOULD NOT SEND STOCK
CERTIFICATES WITH THEIR PROXY CARDS.

                             THE REVERSE STOCK SPLIT

Recommendation of the Dencor Board of Directors.

     Reverse Stock Split. The Dencor Board Of Directors has unanimously approved
and proposed  for  stockholder  approval a 1-for-50  Reverse  Stock  Split.  The
Reverse Stock Split is necessary in order for Dencor to have a sufficient number
of authorized shares with which to complete the Merger. In addition,  the Dencor
Board Of Directors  believes  that the Reverse  Stock Split may be beneficial to
Dencor due to the large  number of shares that  otherwise  would be  outstanding
after the Merger.  The Dencor Board Of Directors  believes  that the low trading
prices of the Dencor  Common Stock may impair  efficiency  of the market for the
Dencor Common Stock and that brokerage  commissions on the purchase or sale of a
relatively lower priced stock generally tend to represent a higher percentage of
the sales price than the  commission on a relatively  higher  priced stock.  The
Dencor Board Of  Directors  believes  that the Reverse  Stock Split will improve
these  factors and may inure to the benefit of Dencor  shareholders,  Dencor and
the market for the Dencor Common Stock.

     If the Reverse  Stock Split were  effected,  Dencor would have fewer shares
outstanding.  A reduction in the number of shares would  increase the book value
per share as well as the earnings  (or loss) per share.  These  increases  could
make the Dencor Common Stock more attractive to larger brokerage houses, thereby
possibly  expanding  the group of brokers  interested in making a market for the
Dencor Common Stock. Nevertheless,  the Dencor Board Of Directors cannot predict
what effect the Reverse Stock Split would have on the market price of the Dencor
Common Stock.

     If the Reverse  Stock Split is  approved  by the Dencor  shareholders,  the
effective  time for the  Reverse  Stock  Split  will be  immediately  before the
Effective Time of the Merger. Each 50 shares of Dencor Common Stock at that time
shall be deemed to be one share of Dencor Common Stock without further action by
the Dencor  shareholders.  It will not be necessary for a Dencor  shareholder to
exchange certificates representing stock issued prior to the Reverse Stock Split
for certificates representing shares resulting after the Reverse Stock Split.

     If the Reverse Stock Split is effected,  Dencor will not issue certificates
for fractional shares. Instead,  persons who are Dencor shareholders immediately
before the  consummation  of the Merger and who otherwise would be entitled to a
fractional  share would be issued one whole share.  All shares of Dencor  Common
Stock held by a record holder will be  aggregated  for purposes of computing the
number of shares of Dencor Common Stock subject to the Reverse Stock Split.


                                       42



<PAGE>


     Dencor  has not sought and does not intend to seek an opinion of counsel or
a ruling from the Internal  Revenue  Service  regarding  the federal  income tax
consequences  of the Reverse Stock Split.  Based on  consultation  with counsel,
Dencor  believes that a shareholder who does not receive cash in connection with
the Reverse Stock Split would not recognize any gain or loss on the exchange and
Dencor  would not  recognize  any gain or loss as a result of the Reverse  Stock
Split.

THE DENCOR BOARD OF DIRECTORS UNANIMOUSLY  RECOMMENDS THAT THE HOLDERS OF DENCOR
COMMON STOCK VOTE FOR APPROVAL OF THE REVERSE STOCK SPLIT.


                                   THE MERGER

General

     The Merger Agreement,  provides that, subject to the satisfaction or waiver
of the conditions set forth therein (see  "--Conditions  to the  Consummation of
the Merger"), PAI will be merged with and into Sub, a wholly owned subsidiary of
Dencor,  which  will  result  in PAI's  being  the  surviving  corporation  (the
"Surviving  Corporation")  and a wholly-owned  subsidiary of Dencor.  As soon as
practicable after the satisfaction of the conditions under the Merger Agreement,
the Certificate of Merger will be filed with the Secretary of State of the State
of  Delaware,  and the time of such  filing  will be the  Effective  Time unless
otherwise provided in the Certificate of Merger.

     The  description of the Merger and the Merger  Agreement  contained in this
Joint Proxy  Statement/Prospectus  is  qualified in its entirety by reference to
the Merger Agreement.

Background of the Merger

     In November 1996, Mr. Ogen Perry, of Helix Capital,  LLC,  contacted Dencor
to discuss a possible  merger with PAI. On November 25,  1996,  Mr.  Perry,  Mr.
Christopher  Condy, the President,  Chief Operating  Officer,  and a director of
PAI, Mr. George Pilloton, the Chief Financial Officer and a director of PAI, and
Tom Adams, Principal,  Technical Services of PAI met with Dencor representatives
at the  Dencor  offices.  At that  meeting,  PAI  representatives  presented  an
overview of PAI's  business  and  operations.  This meeting  concluded  with PAI
representatives  requesting Maynard Moe, the Chairman of the Board and President
of Dencor,  to visit the PAI  offices and to further  discuss a possible  merger
between Dencor and PAI.

     On December 4, 1996, Dr. Moe visited the PAI offices to further discuss the
possible merger. At that meeting,  Dr. Moe reviewed the financial  statements of
PAI, and discussed with PAI representatives  certain business operations of PAI.
During  that  meeting,  Mr.  Perry  proposed a framework  for a possible  merger
between PAI and Dencor.

     During  the  period  from   December   12,   1996  to  January  19,   1997,
representatives of each of PAI and Dencor further  discussed,  through telephone
conversations and written  communications,  a proposed  framework for a possible
merger.



                                       43

<PAGE>


     In April of 1997, Mr. Perry contacted  representatives of Dencor to further
discuss the proposed merger. On April 5, 1997, PAI  representatives  visited the
Dencor  offices  and  presented  to the  Dencor  Board of  Directors  a proposed
framework for a possible merger between PAI and Dencor.

     On May 8 and 9, 1997, Dr. Moe, Carol Moe, the wife of Dr. Moe, and Theodore
Hedman, the Vice President,  Secretary, Manager of Engineering and a director of
Dencor,  met with PAI  representatives  at the PAI offices.  At these  meetings,
several  items of due  diligence  and the proposed  framework of the merger were
discussed.

     On May 28,  1997,  the Dencor  Board of  Directors  approved a  non-binding
letter of intent to merge with PAI,  subject to additional  work  concerning the
transaction being done,  negotiation of a definitive contract,  and the approval
of the holders of the common stock of each company, if necessary.

     The ratio upon which PAI Common Stock will be exchanged  for Dencor  Common
Stock  was  determined  as a result  of arms  length  negotiations  between  the
representatives of PAI and the representatives of Dencor. The Exchange Ratio was
determined after consideration of a number of factors,  including the following:
(i) the existing  capitalization  of each of Dencor and PAI, (ii) the nature and
future  prospects  of the  businesses  of each of Dencor and PAI,  and (iii) the
matters  described  below with respect to the reasons the Boards of Directors of
each of Dencor and PAI have  concluded  that the proposed  Merger is in the best
interest  of the  holders  of their  respective  shares  of  common  stock.  See
"--Recommendation of the Boards of Directors; Reasons for the Merger."

Recommendations of the Boards of Directors; Reasons for the Merger

     Recommendation of the Dencor Board of Directors; Reasons for the Merger

     Merger.  At a meeting  held on August 5, 1997,  the Board of  Directors  of
Dencor  determined  that the  Merger  is fair to and  advisable  and in the best
interests of the holders of shares of Dencor Common  Stock,  approved the Merger
Agreement,  the  Merger  and the other  transactions  contemplated  thereby  and
resolved to recommend  that the holders of shares of Dencor Common Stock vote in
favor of the Charter Amendments and the Reverse Stock Split.

     In reaching  these  conclusions,  the Dencor Board of Directors  considered
among other things,  (i) the existing assets and business  operations of each of
Dencor and PAI, (ii) the management  experience of each of Dencor and PAI, (iii)
the earnings  record,  operations and financial  condition of each of Dencor and
PAI,  (iv) the  judgment of the Dencor  Board of  Directors as to the nature and
future  prospects of the businesses of Dencor and PAI, (v) the  compatibility of
the respective businesses of Dencor and PAI, (vi) current industry, economic and
market  conditions,  (vii) the terms of the  Merger  Agreement,  and  (viii) the
ability of the combined entity to compete in relevant markets.

     The Board of Directors of Dencor  believes that the Merger will result in a
stronger combined entity with the financial and management  resources to compete
effectively and to take advantage of opportunities  that may not be available to
either  company on its own.  Dencor  management  believes that this  transaction
allows Dencor and PAI to expand  substantially  in a single  strategic  move. In
particular,  the Dencor  directors  concluded  that the  transaction  is fair to
Dencor and its  shareholders  because,  among  other  things,  (i) the  business


                                       44

<PAGE>

operations  of PAI  provide a  potential  use of and an  established  market for
Dencor products,  (ii) PAI possesses  marketing and  distribution  personnel and
expertise that Dencor believes will assist in the marketing of Dencor  products,
and (iii) Proven Alternatives Capital Corporation,  a wholly owned subsidiary of
PAI  that  develops  investment  vehicles  and  provides  related  services  for
sophisticated  institutional  investors to provide  project  financing  for PAI,
potentially could provide financing for the manufacture of Dencor products.  The
manufacture  of certain  Dencor  products  currently  is  financed by loans from
Dencor shareholders.

     The foregoing  discussion of the  information  and factors  considered  and
given weight by the Dencor Board of Directors is not intended to be  exhaustive.
In view of the variety of factors  considered in connection  with its evaluation
of the Merger,  the Dencor Board of Directors did not find it practicable to and
did not quantify or otherwise  assign relative  weights to the specific  factors
considered in reaching its determination. In addition, individual members of the
Dencor Board of Directors may have given different weights to different factors.
For a discussion of the interests of certain  members of Dencor  management  and
the Dencor  Board of  Directors in the Merger,  see "THE  MERGER--  Interests of
Certain Persons in the Merger."

     The  Board of  Directors  of Dencor  did not  obtain  an  opinion  from any
financial advisor concerning the value of PAI or the fairness of the Merger.

     The Board of  Directors  of Dencor  realizes  that there are certain  risks
associated  with the Merger,  including that some of the potential  benefits set
forth above may not be realized or that there may be high costs  associated with
realizing  such  benefits  and also the  factors  set forth in this Joint  Proxy
Statement/Prospectus  under "RISK FACTORS".  However,  the Board of Directors of
Dencor believes that the positive factors should outweigh any negative  factors,
although there can be no assurance in that regard.

     Charter  Amendments.  The  Board of Dencor  has  unanimously  approved  and
proposed  for  shareholder   approval  an  amendment  to  Dencor's  Articles  of
Incorporation  to authorize a new class of capital stock consisting of 1,000,000
shares of preferred  stock, no par value (the "Dencor  Preferred  Stock"),  with
such relative  rights,  preferences and designations as may be determined by the
Board in its sole  discretion  upon the  issuance  of any  shares of the  Dencor
Preferred  Stock.  The proposal to  authorize a new class of Preferred  Stock is
intended to provide shares of Dencor  Preferred  Stock for issuance from time to
time as may be required for various  other  purposes,  including the issuance of
Dencor Preferred Stock in connection with financing or acquisition transactions.
The Dencor Preferred Stock may be utilized after the Merger for financing sought
by PAI. See "PAI MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS" and "POST-MERGER PROFILE". For a description of the terms
of the PAI Preferred  Stock,  see  "DESCRIPTION  OF CAPITAL  STOCK OF PAI".  The
shares of Dencor  Preferred Stock could be issued from time to time by the Board
in  its  sole  discretion  without  further  approval  or  authorization  by the
shareholders of Dencor,  in one or more series,  each of which series could have
any  particular  distinctive   designations  as  well  as  relative  rights  and
preferences  as  determined  by the Board of  Dencor.  The  relative  rights and
preferences  that may be determined by the Board in its discretion  from time to
time,  include but are not limited to the  following:  the rate of dividend  and
whether the dividends are to be cumulative and the priority, if any, of dividend
payments  relative to other series in the class;  whether the shares of any such
series  may be  redeemed,  and if so,  the  redemption  price  and the terms and


                                       45

<PAGE>


conditions of  redemption;  the amount  payable upon such series in the event of
voluntary of involuntary  liquidation  and the priority,  if any, of each series
relative  to other  series in the class with  respect to  amounts  payable  upon
liquidation and sinking fund  provision,  if any, for the redemption or purchase
of the shares of that  series;  the terms and  conditions,  if any, on which the
shares of a series may be converted  into or exchanged  for shares of any class,
whether common or preferred, or into shares of any series of the same class, and
if  provision is made for  conversion  or exchange,  the times,  prices,  rates,
adjustments and other terms.

     The existence of authorized but unissued  shares of Dencor  Preferred Stock
could have  anti-takeover  effects  because Dencor could issue Dencor  Preferred
Stock with special  dividend or voting  rights that could  discourage  potential
bidders.

     THE DENCOR BOARD OF DIRECTORS  UNANIMOUSLY  RECOMMENDS  THAT THE HOLDERS OF
DENCOR COMMON STOCK VOTE FOR APPROVAL OF THE CHARTER AMENDMENTS.

     Recommendation of the PAI Board of Directors; Reasons for the Merger

     By the  unanimous  vote of the  Board of  Directors  at a  meeting  held on
 .............,  1997,  the PAI  Board  determined  the  Merger to be fair to and
advisable and in the best interests of PAI and its stockholders and approved the
Merger and the Merger Agreement.

     At its meeting held on  ...............,  1997,  the PAI Board received the
presentation of management with respect to Dencor,  including  reviews of, among
other  things:  historical  information  relating  to  the  business,  financial
condition  and  results of  operations  of  Dencor;  information  regarding  the
management  of Dencor;  historical  data  relating to market  prices and trading
volumes of Dencor Common Stock; and the likely effects of the Merger on Dencor's
financial condition, including the dilutive effects of the issuance of shares of
Dencor Common Stock in the Merger, and the market effects of the announcement of
the proposed Merger and the consummation thereof on the Dencor Common Stock.

     During  the  course  of its  deliberations,  the  PAI  Board  of  Directors
considered  a  number  of  other  factors,  including  the  following:  (i)  the
historical  performance and strategic objectives of Dencor, as well as the risks
involved in achieving those prospects and objectives  under current economic and
market  conditions,  (ii) the  structure  of the Merger,  which would permit the
holders of PAI Common Stock to exchange  all their  shares  solely for shares of
Dencor Common Stock on a tax free basis, (iii) the expected accounting treatment
of the Merger as a pooling of interests, (iv) the likelihood that holders of PAI
Common  Stock would have  greater  liquidity  in their  holdings in the combined
entity following the Merger, (v) the existing assets and business  operations of
each of Dencor and PAI,  (vi) the  management  experience  of each of Dencor and
PAI, (vii) the earnings  record,  operations and financial  condition of each of
Dencor and PAI,  (viii) the  judgment of the Board of Directors of PAI as to the
nature and future  prospects of the  businesses  of Dencor and PAI, and (ix) the
compatibility of the respective businesses of Dencor and PAI.

     In particular,  the PAI directors concluded that the transaction is fair to
PAI and its  stockholders,  because,  among other things,  (i) Dencor  possesses
expertise  in the  development  and  manufacturing  of products and systems that
assist in controlling the cost of energy utilization and would be useful for



                                       46

<PAGE>


energy cost control programs implemented for PAI's customers, and (ii) Dencor is
a publicly held company and potentially could obtain  additional  capital in the
public markets for PAI's operations, of which there is no assurance.

     The foregoing  discussion of the  information  and factors  considered  and
given weight by the PAI Board is not intended to be  exhaustive.  In view of the
variety of factors  considered in connection  with its evaluation of the Merger,
the PAI Board of Directors did not find it  practicable  to and did not quantify
or otherwise  assign  relative  weights to the specific  factors  considered  in
reaching its determination.  In addition, individual members of the PAI Board of
Directors  may  have  given  different  weights  to  different  factors.  For  a
discussion of the  interests of certain  members of PAI  management  and the PAI
Board of Directors in the Merger, see "THE  MERGER--Interests of Certain Persons
in the Merger."

     The Board of Directors of PAI did not obtain an opinion from any  financial
advisor concerning the value of Dencor or the fairness of the Merger.

     The  Board of  Directors  of PAI  realized  that  there are  certain  risks
associated  with the Merger,  including that some of the potential  benefits set
forth above may not be realized or that there may be high costs  associated with
realizing  such  benefits  and also the  factors  set forth in this Joint  Proxy
Statement/Prospectus  under "RISK FACTORS".  However,  the Board of Directors of
PAI believes that the positive  factors  should  outweigh any negative  factors,
although there can be no assurance in that regard.

     Based  on  the  factors   described  above,  the  PAI  Board  of  Directors
unanimously  declared the Merger fair to and advisable and in the best interests
of the holders of PAI Common Stock.

THE BOARD OF  DIRECTORS  OF PAI  UNANIMOUSLY  RECOMMENDS  TO THE  HOLDERS OF PAI
COMMON STOCK THAT THE MERGER AND THE MERGER AGREEMENT BE APPROVED.

Merger Consideration

     Subject to certain provisions as described herein with respect to shares of
PAI Common Stock owned by PAI,  Dencor or any subsidiary of PAI or Dencor,  upon
consummation of the Merger each issued and outstanding share of PAI Common Stock
will be converted into 1.5 validly issued,  fully paid and nonassessable  shares
of Dencor  Common Stock  before  giving  effect to the Reverse  Stock Split (.03
shares of Dencor Common Stock after giving effect to the Reverse Stock Split).

     Fractional  shares of Dencor Common Stock will not be issued in the Merger.
See "--Fractional Shares" below.

     The Exchange Ratio was determined through  negotiations  between Dencor and
PAI.  Based on the  number of shares of PAI  Common  Stock and the number of PAI
Stock Options outstanding on the PAI Record Date, a maximum of 42,127,272 shares
of Dencor Common Stock may be issued in respect of shares of PAI Common Stock in
the Merger and  6,886,926  shares would be reserved for issuance  upon  exercise
under the terms of PAI Stock Options  which,  pursuant to the Merger  Agreement,
following  the merger will  constitute  options to purchase  Dencor Common Stock
upon the terms set forth in the Merger Agreement and the PAI Stock Options.


                                       47


<PAGE>

     Any shares of PAI Common Stock owned by PAI or any of its  subsidiaries  or
by Dencor will  automatically  be cancelled at the Effective Time and will cease
to exist and no capital stock of Dencor or other consideration will be delivered
in exchange therefor.

Effective Time of the Merger

     The Merger  will become  effective  upon the filing and  acceptance  of the
Certificate  of Merger with the  Secretary  of State of the State of Delaware or
such  later  date  as is  specified  in  such  Certificate.  The  filing  of the
Certificate  of  Merger  will  occur  as  soon  as  practicable   following  the
satisfaction or waiver of the conditions set forth in the Merger Agreement.  See
"CERTAIN PROVISIONS OF THE MERGER AGREEMENT--Conditions to the Merger."

     The Merger Agreement  provides that,  subject to certain  limitations,  the
Merger  Agreement  may be  terminated by one or all parties at any time prior to
the filing of the Certificate of Merger with the Delaware Secretary of State if,
among other reasons,  the Merger has not been  consummated on or before December
31,  1997,   notwithstanding   approval  of  the  Merger  Agreement  or  related
transactions by the  stockholders of PAI or Dencor.  See "CERTAIN  PROVISIONS OF
THE MERGER AGREEMENT-- Termination."

Conversions of Shares; Procedures for Exchange of Certificates

     The  conversion  of PAI Common Stock into Dencor Common Stock will occur at
the Effective Time. As soon as practicable after the Effective Time, Dencor will
deposit with American  Securities  Transfer & Trust Co., Inc., as exchange agent
(the "Exchange  Agent"),  for the benefit of the holders of  certificates  which
immediately  prior to the Effective Time represented  shares of PAI Common Stock
(the "Certificates") certificates representing the shares of Dencor Common Stock
(such  shares  of  Dencor   Common   Stock,   together  with  any  dividends  or
distributions with respect thereto payable as described below, being hereinafter
referred to as the "Exchange Fund") issuable in exchange for outstanding  shares
of PAI Common Stock.

     As soon as  practicable  after the Effective  Time, the Exchange Agent will
mail to each holder of record of a Certificate  whose shares are converted  into
shares of Dencor Common Stock a letter of  transmittal  (which will specify that
delivery will be effected,  and risk of loss and title to the Certificates  will
pass, only upon actual and proper  delivery of the  Certificates to the Exchange
Agent and will contain  instructions  for use in effecting  the surrender of the
Certificates in exchange for certificates  representing  shares of Dencor Common
Stock and will be in such form and contain such other  provisions  as Dencor and
PAI may reasonably specify). Upon surrender of a Certificate for cancellation to
the Exchange Agent, together with such letter of transmittal, duly executed, the
holder of such  Certificate  will be entitled to receive in exchange  therefor a
certificate  representing  that number of whole  shares of Dencor  Common  Stock
which such  holder  has the right to receive  pursuant  to the  Merger,  and the
Certificate so  surrendered  will be cancelled.  Until  surrendered as described
above,  each  Certificate  will, at and after the  Effective  Time, be deemed to
represent  only the right to receive,  upon surrender of such  Certificate,  the


                                       48

<PAGE>


certificate representing the appropriate number of shares of Dencor Common Stock
and certain dividends and other distributions as described below.

     PAI STOCKHOLDERS  SHOULD NOT FORWARD PAI STOCK CERTIFICATES TO THE EXCHANGE
AGENT UNTIL THEY HAVE RECEIVED THE LETTER OF TRANSMITTAL.

     No  dividends  or other  distributions  that are  declared  on or after the
Effective  Time on Dencor  Common  Stock or are payable to the holders of record
thereof  on or after the  Effective  Time will be paid to  persons  entitled  by
reason of the Merger to receive  certificates  representing  Dencor Common Stock
until such persons surrender their Certificates,  as described above. Subject to
the effect of  applicable  law,  there will be paid to the record  holder of the
certificates  representing  such  Dencor  Common  Stock  (i) at the time of such
surrender or as promptly as practicable thereafter,  the amount of any dividends
or other  distributions  theretofore  paid with  respect to whole shares of such
Dencor Common Stock and having a record date on or after the Effective  Time and
a payment date prior to such surrender and (ii) at the appropriate  payment date
or as promptly  as  practicable  thereafter,  the amount of  dividends  or other
distributions  payable with  respect to whole shares of Dencor  Common Stock and
having a record date on or after the Effective Time but prior to surrender and a
payment date  subsequent to surrender.  In no event will the person  entitled to
receive such dividends or other distributions be entitled to receive interest on
such dividends or other distributions.  If any cash or certificate  representing
shares of Dencor  Common  Stock is to be paid to or issued in a name  other than
that in which the Certificate surrendered in exchange therefor is registered, it
will be a condition of such  exchange that the  Certificate  so  surrendered  be
properly  endorsed and otherwise in proper form for transfer and that the person
requesting  such exchange pay to the Exchange  Agent any transfer or other taxes
required  by reason of the  issuance of  certificates  for such shares of Dencor
Common  Stock  in a name  other  than  that  of  the  registered  holder  of the
Certificate surrendered,  or establish to the satisfaction of the Exchange Agent
that such tax has been paid or is not applicable.

Fractional Shares

     No certificates or scrip  representing  fractional  shares of Dencor Common
Stock will be issued upon the surrender for exchange of Certificates pursuant to
the Merger  Agreement,  and no Dencor  dividend or other  distribution  or stock
split or combination will relate to any fractional security, and such fractional
interests  will not  entitle  the owner  thereof  to vote or to any  rights of a
security  holder of Dencor.  No  fractional  shares will be issued in connection
with the Merger. In lieu thereof,  each PAI stockholder  entitled to receive 0.5
or more of a share of Dencor  Common  Stock shall  receive  the total  number of
whole shares of Dencor  Common Stock to which he or she is entitled and a single
whole share of Dencor Common Stock in place of the  fractional  share.  Each PAI
stockholder  who would be entitled to receive less than 0.5 of a share of Dencor
Common Stock shall  receive only the total number of whole shares to which he or
she is  entitled,  and any such  fractional  share shall be  eliminated  for all
purposes without compensation for the fractional share.

     Any portion of the Exchange Fund which remains  undistributed to the former
stockholders  of PAI for one year after the Effective  Time will be delivered to
Dencor,  upon demand of Dencor, and any former  stockholders of PAI who have not
theretofore  complied with the provisions  described  above will thereafter look
only to Dencor  for  payment  of their  claim for  Dencor  Common  Stock and any


                                       49

<PAGE>


dividends or distributions  with respect to Dencor Common Stock. None of Dencor,
PAI or the surviving  corporation  of the Merger will be liable to any holder of
shares of PAI Common  Stock for  shares  (or  dividends  or  distributions  with
respect thereto) of Dencor Common Stock delivered to a public official  pursuant
to any applicable abandoned property, escheat or similar law.

Conduct of Business Pending Merger

     Pursuant  to the Merger  Agreement,  Dencor and PAI have each  agreed  that
during the period from the date of the Merger  Agreement  through the  Effective
Time  (except  as  otherwise  specifically  required  by the terms of the Merger
Agreement), it will, and it will cause its respective subsidiaries,  if any, to,
in all material respects,  carry on their respective  businesses in the ordinary
course and consistent with past practice and, to the extent consistent therewith
and with the  terms of the  Merger  Agreement,  use all  reasonable  efforts  to
preserve  intact  their  current  business  organizations,  keep  available  the
services  of  their  current   officers  and   employees   and  preserve   their
relationships with customers, suppliers and others having business dealings with
them to the end that their goodwill and ongoing businesses will be unimpaired at
the Effective Time. The parties also have agreed to certain other covenants,  as
described herein under "CERTAIN PROVISIONS OF THE MERGER  AGREEMENT--Conduct  of
Business Pending the Merger."

Conditions to the Consummation of the Merger

     The  obligations  of Dencor and PAI to consummate the Merger are subject to
various  conditions,  including,  among other  things,  obtaining  the requisite
stockholder approvals,  the effectiveness of the Registration Statement, and the
absence of any order or other legal  restraint  or  prohibition  preventing  the
consummation  of the Merger.  The  obligation of PAI to consummate the Merger is
subject  to  the  fulfillment  or  waiver  of  various  additional   conditions,
including,  among other things,  Dencor's  compliance with the Merger Agreement.
See  "--Governmental  and Regulatory  Approvals" and "CERTAIN  PROVISIONS OF THE
MERGER AGREEMENT--Conditions to the Merger."

Governmental and Regulatory Approvals

     The Merger is not subject to governmental or regulatory approvals.

Certain Federal Income Tax Consequences

     The following is a general summary of the material U.S.  federal income tax
consequences  of the Merger to the  holders  of PAI  Common  Stock and PAI Stock
Options and is based upon current  provisions of the Code,  existing,  temporary
and final  regulations  thereunder  and the current  administrative  rulings and
court  decisions  all of which are subject to change  (possibly on a retroactive
basis).  No  attempt  has been made to comment  on all U.S.  federal  income tax
consequences of the Merger that may be relevant to particular holders, including
holders  that are  subject to special  tax rules such as dealers in  securities,
mutual funds,  insurance  companies,  tax-exempt entities and holders who do not
hold their shares as capital assets.


                                       50

<PAGE>


     The tax  discussion  set forth  below is included  for general  information
only.  It is not  intended to be, nor should it be construed to be, legal or tax
advice to any  particular  holder  of PAI  Common  Stock or PAI  Stock  Options.
Holders of PAI Common  Stock or PAI Stock  Options are  advised and  expected to
consult with their own legal and tax advisers  regarding the U.S. federal income
tax consequences of the Merger in light of their particular  circumstances,  and
any other  consequences to them of the Merger under state, local and foreign tax
laws.

     Exchange of PAI Common Stock Pursuant to the Merger.

     General.  Subject to the discussion set out below,  the U.S. federal income
tax consequences of the Merger will be as follows:

          (i) the Merger will constitute a  "reorganization"  within the meaning
     of Section 368(a) of the Code and PAI,  Dencor and Sub will each be a party
     to that reorganization within the meaning of Section 368(b) of the Code;

          (ii) no gain or loss will be  recognized by PAI,  Dencor,  or Sub as a
     result of the Merger;

          (iii) no gain or loss will be  recognized by the  stockholders  of PAI
     who are United States  persons within the meaning of the Code (each a "U.S.
     Stockholder")  upon the conversion of their PAI Common Stock into shares of
     Dencor Common Stock pursuant to the Merger;

          (iv) the aggregate basis of the shares of Dencor Common Stock received
     by a U.S.  Stockholder  in exchange for shares of PAI Common Stock pursuant
     to the Merger will be the same as the  aggregate  federal  income tax basis
     for such shares of PAI Common Stock at the time of the Merger; and

          (v) the holding period for shares of Dencor Common Stock received by a
     U.S. Stockholder in exchange for shares of PAI Common Stock pursuant to the
     Merger will include the holding  period of such shares of PAI Common Stock,
     provided such shares of PAI Common Stock were held as capital assets by the
     holder at the Effective Time.

     The foregoing is based upon the  assumption  that the Merger is carried out
in  accordance   with  the  Merger   Agreement  and  the  assumption   that  the
representations  and warranties  contained in the Merger  Agreement are true and
correct and will be true and correct as of the Effective  Time as though made as
of the Effective Time.

     One of the requirements for a tax-free  reorganization is that stockholders
of PAI retain a  significant  continuing  equity  interest  in Dencor  after the
Merger. In that regard, the foregoing is based on the assumption that, as of the
Effective Time of the Merger,  there will be no plan or intention on the part of
the  stockholders of PAI to sell,  exchange or otherwise  dispose of a number of
shares of Dencor  Common Stock  received in the Merger that would reduce the PAI
stockholders'  ownership of Dencor  Common Stock to a number of shares  having a
value,  as of the date of the  Merger,  of less than 50% of the value of all the
formerly  outstanding  shares  of PAI  Common  Stock  as of the same  date.  For


                                       51



<PAGE>


purposes of this  assumption,  shares of PAI Common Stock  exchanged for cash or
other  property will be treated as  outstanding  PAI Common Stock on the date of
the Merger.  Moreover,  shares of PAI Common Stock otherwise  sold,  redeemed or
disposed  of prior to the  Merger in  connection  with the  Merger  will also be
considered for purposes of this  assumption.  PAI has  represented in the Merger
Agreement to the effect that, to the knowledge of the executive officers of PAI,
such  assumption is correct.  However,  if a  significant  portion of the Dencor
Common Stock  received by PAI  stockholders  in the Merger is sold shortly after
the Merger,  the Merger could be treated as a taxable  transaction  in which all
stockholders of PAI (including stockholders who did not sell their Dencor Common
Stock) would  recognize  gain or loss equal to the  difference  between the fair
market value of the Dencor Common Stock  received and the basis of the PAI Stock
surrendered in the Merger.

     Dividends and other distributions paid with respect to the shares of Dencor
Common Stock issued upon  exchange of the PAI Common Stock,  as described  under
"THE MERGER-Conversion of Shares; Procedures for Exchange of Certificates", will
generally  be taxable as dividend  income to the extent of Dencor's  current and
accumulated earnings and profits.

     If the Merger is not treated as a  reorganization  for  federal  income tax
purposes,  no  gain or  loss  will be  recognized  by  Dencor  or PAI.  However,
exchanges  of PAI Common Stock for Dencor  Common  Stock  pursuant to the Merger
will be taxable  transactions  for federal  income tax purposes.  In that event,
each  exchanging  holder of PAI  Common  Stock will  recognize  gain or loss for
federal  income tax  purposes  equal to the  difference  between  such  holder's
adjusted  basis in the PAI Common Stock  exchanged  and the fair market value of
Dencor  Common  Stock  received by such holder in the Merger.  Such gain or loss
will be capital  gain or loss if the  shares of PAI Common  Stock were held as a
capital  asset and will be  long-term  gain or loss if such shares had been held
for more than one year at the time of consummation of the exchanges.

     Non-U.S.  Shareholders. A holder of PAI Common Stock that, for U.S. federal
income tax purposes, is a non-resident alien individual,  a foreign corporation,
a foreign  partnership or a foreign  estate or trust (a "Non-U.S.  Stockholder")
generally  will not be subject to U.S.  federal  income tax (by  withholding  or
otherwise)  on the  receipt  of Dencor  Common  Stock  pursuant  to the  Merger.
However,  if the Merger  were to fail to qualify  as a  reorganization  for U.S.
federal  income tax purposes,  a Non-U.S.  Stockholder  that holds shares of PAI
Common  Stock  will  generally  be  subject  to U.S.  federal  income tax on the
conversion  of PAI Common  Stock into shares of Dencor  Common  Stock if (i) the
resulting income or gain is effectively connected with the conduct of a trade or
business of the Non-U.S. Stockholder within the United States, (ii) the Non-U.S.
Stockholder is a non-resident  alien individual present in the United States for
183 days or more in the taxable year of the Merger and certain other  conditions
are met, or (iii) the  Non-U.S.  Stockholder  is subject to tax  pursuant to the
provisions  of  U.S.  federal  tax  law  applicable  to  certain  United  States
expatriates. Different rules may apply to any amounts treated as dividend income
under the rules referred to above.

     Dividends  on Dencor  Common  Stock  paid to a  Non-U.S.  Stockholder  will
generally be subject to a U.S. withholding tax.

Anticipated Accounting Treatment


                                       52

<PAGE>


     Dencor and PAI expect that the Merger will qualify for pooling of interests
accounting  treatment.  Under this method of  accounting,  Dencor's prior period
financial  statements  will be restated  on a combined  basis with those of PAI,
with all intercompany accounts being eliminated and all expenses relating to the
Merger being deducted from combined income.

Assumption of PAI Stock Options Pursuant to the Merger

     Holders of PAI Stock Options that are assumed by Dencor as described  below
under "CERTAIN PROVISIONS OF THE MERGER  AGREEMENT--PAI Stock Options" generally
will not  recognize  income or gain for federal  income tax  purposes  upon such
assumption, assuming the Merger is a tax-free reorganization as described above.

     A  holder  of  an  assumed  PAI  Stock  Option  will   recognize   ordinary
compensation  income,  and Dencor will be allowed a deduction for federal income
tax  purposes,  on the date such option is  exercised  in an amount equal to the
excess of the fair market value on such date of the Dencor Common Stock acquired
by  exercise of such  option  over the  exercise  price of such shares of Dencor
Common Stock.  The tax basis of the Dencor Common Stock  acquired by exercise of
an  assumed  PAI  Stock  Option  will be its  fair  market  value on the date of
exercise  of such  option and the holding  period for  purposes  of  determining
whether  a  subsequent  sale of the  Dencor  Common  Stock  would  result in the
recognition of short-term or long-term capital gain or loss will commence on the
date of transfer of the Dencor Common Stock to the holder of the option.

     Under  current law, the tax rate imposed on long-term  capital gains cannot
exceed 28%. The Code imposes limitations on the amount of capital loss which can
be deducted in a taxable year.

     If the  holder of an assumed  PAI Stock  Option  delivers  shares of Dencor
Common Stock in payment of the exercise  price of the Dencor Common Stock,  such
holder will not recognize  any taxable  income by reason of such  delivery.  The
holder's  basis and  holding  period for the  number of shares of Dencor  Common
Stock received  equal to the number of shares  delivered will be the same as the
shares delivered.  The holder's basis for shares of Dencor Common Stock received
in excess of the number of shares  delivered will equal the fair market value of
such  shares of Dencor  Common  Stock  used to  determine  the amount of taxable
compensation  arising from the exercise of such option.  The holding  period for
such excess  shares of Dencor  Common Stock will commence on the date the shares
of Dencor Common Stock are transferred to the holder.

     Amounts  described above as being treated as  compensation  income upon the
exercise  of an  assumed  PAI  Stock  Option  will be  subject  to tax at  rates
applicable  to  ordinary  income and will be  subject  to tax under the  Federal
Insurance  Contribution Act (i.e., FICA tax), (subject to certain limitations in
the case of the old-age,  survivors and disability insurance portion of the FICA
tax). The number of shares of Dencor Common Stock otherwise issuable to a holder
of an assumed PAI Stock Option which is exercised  may be reduced by a number of
shares of Dencor  Common  Stock  having a total fair  market  value equal to the
foregoing taxes and any other amounts required by law to be withheld.

     A holder of PAI Stock Option who is a non-resident alien individual and who
has such PAI Stock  Option  assumed  and then  exercises  the  assumed PAI Stock
Option  generally  will not be subject to U.S.  federal income tax to the extent


                                       53

<PAGE>


the option is attributable to services performed outside the United States. Such
a holder will  generally  be subject to the rules under FIRPTA  discussed  above
with  respect to the  subsequent  sale,  exchange or other  disposition  of such
shares. See "--Exchange of PAI Common Stock Pursuant to the Merger."

Employee Benefits Matters

     All  employee  benefit  plans of PAI will  remain in effect  following  the
Merger.

Interests of Certain Persons in the Merger

     The  Merger  Agreement  provides  that from and after the  Effective  Time,
Dencor  will  indemnify  and hold  harmless  all past and present  officers  and
directors of PAI and of its  subsidiaries to the full extent such persons may be
indemnified by PAI pursuant to PAI's  Certificate of  Incorporation  and By-laws
for acts or  omissions  occurring  at or prior  to the  Effective  Time and will
advance reasonable  litigation  expenses incurred by such officers and directors
in connection  with  defending any action arising out of such acts or omissions.
See "CERTAIN PROVISIONS OF THE MERGER AGREEMENT--Indemnification."

     Pursuant  to the  Merger  Agreement,  shares of PAI  Common  Stock  held by
executive  officers  and  directors  of PAI  will be  converted  into  the  same
consideration as shares of PAI Common Stock held by other  stockholders.  At the
Effective Time,  outstanding PAI Stock Options will become and represent options
to  acquire a number of shares of Dencor  Common  Stock  equal to the  number of
shares of PAI Common Stock  subject to such PAI Stock Options times the Exchange
Ratio at an  exercise  price  per  share of  Dencor  Common  Stock  equal to the
exercise price per share of PAI Common Stock  immediately prior to the Effective
Time  divided by the  Exchange  Ratio.  See  "CERTAIN  PROVISIONS  OF THE MERGER
AGREEMENT - PAI STOCK OPTIONS."

     In  addition,  the  Merger  Agreement  provides  that PAI will  enter  into
employment  agreements with each of Maynard L. Moe,  President and a Director of
Dencor,  and Theodore A. Hedman,  Vice  President and a Director of Dencor.  The
Merger  Agreement also states that PAI will provide Dencor with sufficient funds
to pay outstanding loans,  including loans made to Dencor by Dr. Moe, Mr. Hedman
and their  relatives.  See  "CERTAIN  DENCOR  RELATIONSHIPS  AND  RELATED  PARTY
TRANSACTIONS".

     At the  Effective  Time,  Dencor's  Board of  Directors  will be Charles T.
Condy, Christopher T. Condy, George F. Pilloton and Maynard L. Moe.

Resale of Dencor Common Stock

     The Dencor Common Stock to be issued  pursuant to the Merger will be freely
transferable, except that shares issued to any PAI stockholder who may be deemed
to be an  "affiliate"  (as  defined  under  the  Securities  Act  and  generally
including,  without  limitation,   directors,  certain  executive  officers  and
beneficial  owners  of 10% or more  of a  class  of  capital  stock)  of PAI for
purposes of Rule 145 under the Securities Act will not be transferable except in
compliance with the Securities Act. This Joint Proxy  Statement/Prospectus  does
not cover  resales  of Dencor  Common  Stock  received  by any person who may be



                                       54



<PAGE>


deemed to be an affiliate of PAI. As described above under "THE  MERGER--Certain
Federal Income Tax Consequences,"  sales of a significant  portion of the shares
of  Dencor  Common  Stock  issued  in  the  Merger  may  adversely   affect  the
qualification  of the Merger as a  tax-free  "reorganization"  for U.S.  federal
income tax purposes.

     Pursuant to the Merger Agreement, PAI has agreed to use its reasonable best
efforts to cause each  person who is an  affiliate  of PAI within the meaning of
Rule 145  under  the  Securities  Act to  deliver  to  Dencor on or prior to the
Effective  Time a written  agreement to the effect that such  affiliate will not
sell, pledge, transfer or otherwise dispose of any shares of Dencor Common Stock
issued to such person  pursuant to the Merger,  except  pursuant to an effective
registration  statement or in compliance  with Rule 145 or an exemption from the
registration  requirements  of the Securities  Act, and that such affiliate will
not sell or in any other way reduce such affiliate's risk relative to any shares
of Dencor  Common  Stock  received  in the Merger  until such time as  financial
results  (including  combined sales and net income) covering at least 30 days of
post-Merger  operations  have been  published,  except as permitted by published
guidance from the Commission.

         UNAUDITED PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

     The  following   unaudited  pro  forma  consolidated   condensed  financial
statements reflect adjustments to the historical consolidated balance sheets and
statements  of income of Dencor and PAI to give effect to the Merger,  using the
Pooling of Interest Method of accounting.  The unaudited pro forma  consolidated
condensed  balance sheet at March 31, 1997 assumes the Merger was consummated as
of March 31, 1997 and the unaudited pro forma consolidated  condensed statements
of income for the years ended  December  31, 1996 and 1995 assume the Merger was
consummated  as of January 1, 1996 and 1995,  respectively.  The  unaudited  pro
forma  consolidated  statements  of income for the three  months ended March 31,
1997 and 1996 assume the Merger was  consummated as of January 1, 1997 and 1996,
respectively.

     The  following  pro  forma  consolidated  financial  statements  have  been
prepared  based on,  and  should be read in  conjunction  with,  the  historical
consolidated  financial  statements and notes thereto of Dencor and PAI that are
included  in this Joint  Proxy  Statement/Prospectus.  The  unaudited  pro forma
consolidated  condensed financial  statements are not necessarily  indicative of
the results of operations that might have occurred had the Merger actually taken
place on the above dates, nor are they indicative of future operating results of
the combined companies.

                   CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1. The pro forma combined per share data for income from  continuing  operations
has been calculated using pro forma combined average shares outstanding. PAI and
Dencor pro forma combined average shares  outstanding have been calculated using
the number of Dencor average shares  outstanding  during the periods  presented,
increased  by the  anticipated  number of shares  of Dencor  common  stock to be
issued to PAI shareholders  using an Exchange Ratio of 1.5 for each share of PAI
Common Stock deemed outstanding during each of the periods presented as if these
shares were  outstanding for the entire period  presented.  The weighted average
shares deemed  outstanding  calculation for PAI does not include shares issuable
upon exercise of fully paid,  fully vested stock options as such shares would be
anti-dilutive.  Such options would increase weighted average shares  outstanding
by approximately  1,592,000 shares for the three months ended March 31, 1997 and
1996 and the years ended  December 31, 1996 and 1995,  1,629,000  shares for the
year ended  December 31, 1994,  and  1,346,000  shares for the nine months ended
December 31, 1993.

          CERTAIN DENCOR RELATIONSHIPS AND DENCOR RELATED TRANSACTIONS

     Dencor has been  involved  in the  following  transaction  with its current
Directors,  Officers  and  relatives of such  persons.  Dencor did not obtain an
independent  determination of the fairness and  reasonableness  of the terms and
conditions of any of these transactions.  Nevertheless, Dencor believes that the
terms of each of these  transactions  are fair and reasonable based on the terms
prevalent in the industry for transactions of similar nature.

             CERTAIN PAI RELATIONSHIPS AND PAI RELATED TRANSACTIONS

     Bank Lines.  PAI had a $3,000,000  working  capital line with U.S.  Bank of
Washington  that expired  March 28, 1997.  The interest  rate was the U.S.  Bank
prime  rate  plus one  half of one  percent.  Draws  were in the form of cash or
letters of credit.  As of  February  28,  1997 the  utilization  of the line was
$2,434,878 in cash and letters of credit  totaling  $348,351.  On March 14, 1997
PAI executed a letter  accepting a proposal by the Silicon Valley Bank,  N.A. of
Santa  Clara,  California,  for a new line in the  amount of  $4,000,000,  which
replaced the U.S. Bank line  effective  March 31, 1997.  The Silicon Valley Bank
line  allows cash draws as well as the  issuance of letters of credit.  The U.S.
Bank line was,  and the Silicon  Valley  Bank line is,  secured by the pledge by
Charles T. Condy of 160,000 shares of the common stock of Cal Energy Company and
his personal guarantee. Mr. Condy receives an annual guarantee fee equal to nine
percent of the average  market price of the stock pledged by Mr. Condy to secure
the credit line.

                   CERTAIN TRANSACTIONS BETWEEN DENCOR AND PAI

     On June 12,  1997,  PAI  advanced  to Dencor a total of $13,000 for working
capital to  purchase  raw  materials  to be used for the  completion  of a large
order.  That loan  accrues  interest  at 10% per annum and must be repaid,  with
interest, on or before July 31, 1997. As of June 30, 1997, the $13,000 principal
amount of the loan was  outstanding and the loan had accrued and unpaid interest
of $55.

     Pursuant to the terms of the Merger Agreement,  PAI has agreed to reimburse
Dencor for Dencor's costs in connection  with the Merger in the event the Merger
is  not  consummated.  These  include  Dencor's  reasonable  costs  of  Dencor's
employees' time as well as reasonable  out-pocket  expenses  associated with the
Merger.  PAI has  advanced  to Dencor  $10,000 to be applied to defray the costs
incurred by Dencor.  Dencor shall  provide PAI with written  accountings  of the
costs  and  expenses  incurred  by  Dencor  pursuant  to a  budget  prepared  in
consultation  with PAI. If it appears to Dencor  that it will incur  expenses in
excess of such budget, it shall immediately advise PAI and the parties will work
to agree to an increase in the budget.

                       DESCRIPTION OF CAPITAL STOCK OF PAI

     The following statements are brief summaries of certain provisions relating
to PAI capital  stock and are  qualified  in their  entirety by reference to the
provisions  of  PAI's  Certificate  of  Incorporation,   as  amended  (the  "PAI
Charter"), and By-Laws (the "PAI By-laws"),  which are incorporated by reference
as  an  exhibit  to  the  Registration  Statement  of  which  this  Joint  Proxy
Statement/Prospectus is a part.

     PAI's authorized  capital  consists of 60,000,000  shares PAI Common Stock,
par value $0.01 per share and 15,000,000  shares of Preferred  Stock,  par value

     Holders of shares of PAI  Common  Stock are  entitled  to one vote for each
share on all matters to be voted on by the  stockholders.  Holders of the shares
are entitled to cumulate  their votes in the election of  directors.  Holders of
shares of PAI Common Stock are entitled to share ratably in  dividends,  if any,
as may be  declared,  from  time  to  time  by the  Board  of  Directors  in its
discretion,   from  funds  legally  available  therefor.   In  the  event  of  a
liquidation,  dissolution or winding up of PAI, the holders of shares of the PAI
Common Stock are entitled to share pro rata all assets  remaining  after payment
in full of all  liabilities.  Holders of PAI Common Stock have no  preemptive or
other  subscription  rights, and there are no conversion rights or redemption or
sinking fund provisions with respect to such shares.

     Holders of shares of PAI Preferred  Stock are entitled to one vote for each
share on all matters to be voted on by the  stockholders.  Holders of the shares
are entitled to cumulate  their votes in the election of  directors.  Holders of
shares of PAI Preferred Stock are entitled to share ratably in dividends up to a
total cash dividend,  payable  semi-annually of 8% of the Liquidation  Value, as
may be declared by the Board of Directors in its discretion,  from funds legally
available therefor. In the event of a liquidation,  dissolution or winding up of
PAI, the holders of shares of the PAI Preferred  Stock are entitled to share pro
rata up to the Liquidation  Value of all assets  remaining after payment in full
of all  liabilities.  Upon completion of a public offering raising more than $10

                       COMPARISON OF RIGHTS OF HOLDERS OF
                    PAI COMMON STOCK AND DENCOR COMMON STOCK

General

     The rights of the  holders of PAI Common  Stock are  currently  governed by
PAI's  Certificate  of  Incorporation  (the "PAI Charter") and By-laws (the "PAI
By-laws")  and the laws of  Delaware,  including  the  DGCL.  If the  Merger  is
consummated, holders of PAI Common Stock will become shareholders of Dencor, and
the rights of such former PAI  stockholders  will  thereafter be governed by the
Dencor  Articles of  Incorporation  (the  "Dencor  Charter")  and the By-laws of
Dencor (the "Dencor By-laws") and the laws of Colorado,  including the CBCA. The
following  summary,  which does not  purport to be a complete  statement  of the
differences   between  the  rights  of  the   shareholders  of  Dencor  and  the
stockholders of PAI, sets forth certain  differences  between the Dencor Charter



                                       67
<PAGE>


and the PAI Charter and the Dencor By-laws and the PAI By-laws.  This summary is
qualified  in its  entirety  by  reference  to the  full  text  of  each of such
documents and the applicable Delaware and Colorado statutes.

Voting Rights

     Section  212 of the DGCL  provides  that unless  otherwise  provided in the
certificate of incorporation,  each stockholder is entitled to one vote for each
share of capital stock held by such  stockholder.  Section 7-107-202 of the CBCA
provides that unless otherwise  provided in the Articles of Incorporation,  each
outstanding  share  is  entitled  to one  vote  or  each  matter  voted  on at a
shareholders' meeting.

     The PAI Charter and By-laws provide that each holder of PAI Common Stock is
entitled  to one vote for each share  held by such  holder on all  matters  upon
which holders of PAI Common Stock are entitled to vote.  Corporate  action taken
by vote of PAI  stockholders  must be authorized by the vote of the holders of a
majority  of the  outstanding  shares of all  classes of stock  entitled to vote
thereon  present  in person or by proxy at the  meeting.  Holders  of PAI Common
Stock are  entitled to cumulate  their votes in the election of  directors.  The
Dencor  Charter and By-laws  provide that each  shareholder  of record of Dencor
Common  Stock is entitled to one vote for every share of such stock held by such
stockholder.  Whenever  any  corporate  action  is to be  taken  by  vote of the
shareholders of Dencor, it must be authorized by a majority of the votes cast at
a meeting of shareholders by the holders of shares entitled to vote thereon. The
holders of Dencor  Common Stock are not entitled to cumulate  their votes in the
election of directors.

Classified Board of Directors

     Section  141(d)  of  the  DGCL  provides  that  a  corporation  may  have a
classified  board of directors  providing  for up to three  classes of directors
each having a term of up to three years, and newly elected directors selected by
the board of directors  may serve to the  expiration of the term of the class to
which  they  are  named.  Section  7-108-  106  of  the  CBCA  provides  that  a
corporation's  articles of incorporation may provide for staggering the terms of
directors by dividing the total number of directors into up to three groups with
each group having a term of up to three years,  and newly elected  directors may
serve to the expiration of the term of the group to which they are named.

     Neither the PAI Charter nor the PAI By-laws provide for separate classes of
board of directors.  Neither the Dencor Charter nor the Dencor  By-laws  provide
for staggering the terms of the directors.

Number of Directors

     The number of  directors of a Delaware or a Colorado  corporation  shall be
fixed by, or in the  manner  provided  in, the  by-laws  unless  such  number is
changed by action of the majority of the directors. Under each of Section 141(b)
of the DGCL, and Section  7-108-102 of the CBCA, a director need not be a holder
of the corporation's  stock to be qualified unless so required by the charter or
by-laws.

     The PAI By-laws  provide that the number of directors  shall not consist of
less than three nor more than  twenty.  The  Dencor  Charter  provides  that the
number of  directors  shall not  consist  of less than three nor more than five.
Dencor  Directors  are elected at each annual  meeting of  shareholders  or at a
special meeting of the shareholders.


Filling Vacancies on the Board of Directors


                                       68

<PAGE>


     Each of Section 223 of the DGCL and Section  7-108-110  of the CBCA provide
that,  unless  otherwise  provided  in the  corporation's  charter  or  by-laws,
vacancies,  including  those due to removal  without  cause,  and newly  created
directorships  may be filled by majority vote of the  directors  then in office,
even if the number of directors then in office is less than a quorum.

     The PAI Bylaws provide that newly created  directorships  resulting from an
increase in the number of directors and vacancies  occurring in the Board may be
filled by vote of a majority of the directors then in office,  even if less than
a quorum exists. A PAI director  elected to fill a vacancy,  including a vacancy
created by a newly created  directorship,  shall serve until the next succeeding
annual meeting of stockholders and until his successor is elected and qualified.
The  Dencor  By-laws  provide  that  any  vacancies   (including  newly  created
directorships) may be filled by a majority vote of the directors then in office,
though less than a quorum, or by a sole remaining director.  Any Dencor director
elected  to fill a  vacancy  shall be  elected  for the  unexpired  term of such
director's predecessor in office. Any Dencor directorship to be filled by reason
of an  increase  in the number of  directors,  shall be filled by election at an
annual meeting or at a special meeting of shareholders called for that purpose.

Removal of Directors

     Each of  Section  141(k)  of the DGCL  and  Section  7-108-108  of the CBCA
provide that any director may be removed,  with or without cause,  by a majority
of the shares  then  entitled  to vote at an  election  of  directors.  However,
Section 141(k)(1) of the DGCL provides that, in the case of a corporation with a
classified  board of directors,  such as PAI, a director may be removed only for
cause unless the certificate of incorporation provides otherwise.

     The PAI Charter and By-laws  provide that any of the PAI  directors  may be
removed for cause by vote of a majority of the entire Board of Directors. Any or
all of the PAI  directors  may be removed for cause or without  cause by vote of
the  holders of a  majority  of the  outstanding  shares of each class of voting
stock of PAI  voting as a class.  Neither  the  Dencor  Charter  nor the  Dencor
By-laws contain a provision regarding the removal of directors.

Quorum of Stockholders/Shareholders

     Each of the PAI By-laws and the Dencor By-laws  provide that the holders of
a majority of the shares of the outstanding stock entitled to vote, in person or
by proxy, constitute a quorum at any meeting of the holders of the corporation's
stock for the transaction of business.

Call of Special Shareholder/Stockholder Meetings

     Under each of Section 211(d) of the DGCL and Section 7-107-102 of the CBCA,
special  meetings of stockholders  may be called by the board of directors or by
such other person or persons authorized to do so by the corporation's charter or
by-laws.



                                       69
<PAGE>

     The PAI By-laws provide that special meetings of stockholders may be called
at any time for any purpose by the Board of Directors or by the  president,  and
shall be called by the  president or the secretary  upon the written  request of
the majority or the  directors or upon the written  request of the holders of at
least 10% of all  outstanding  shares entitled to vote on the action proposed to
be taken.  The Dencor By-laws provide that special  meetings of the shareholders
may be called by the President or by the Board of Directors, and shall be called
by the  President  at the  request  of the  holders  of not less than 25% of all
outstanding shares of Dencor entitled to vote at the meeting.

Stockholders'/Shareholders' Action without a Meeting

     Section  228  of  the  DGCL  provides  that,   unless  the  certificate  of
incorporation  provides  otherwise,  stockholders  may take any action without a
meeting by written consent signed by the holders of outstanding stock having not
less than the minimum  number of votes that would be  necessary  to authorize or
take such action at a meeting at which all shares  entitled to vote thereon were
present  and  voted.  Prompt  notice of the  taking  of any  action by less than
unanimous  consent  must be given to  stockholders  who did not  consent to such
action.  Section  7-107-104 of the CBCA  provides  that,  unless the Articles of
Incorporation require that such action be taken at a shareholders'  meeting, any
action  required to be taken at a  shareholders'  meeting may be taken without a
meeting if all of the  shareholders  entitled  to vote  thereon  consent to such
action in writing.

     The PAI By-laws  contain a provision  similar to the  provision of the DGCL
above.  The Dencor By-laws  contain a provision  similar to the provision of the
CBCA above.

Amendments to Charter

     Under each of Section 242 of the DGCL and Section  7-110-101 of the CBCA, a
corporation  can amend its charter in any respect;  provided  that the amendment
contains only  provisions  which would have been lawful in the original  charter
document.  Each of the DGCL and CBCA provide that an amendment may be authorized
by the  adoption of a  resolution  setting  forth the  amendment by the board of
directors  followed by a majority vote of shares entitled to vote thereon.  Each
of the DGCL and CBCA also  provide  for  approval  by vote of the  holders  of a
majority  of  outstanding  shares  of a  particular  class of  stock in  certain
circumstances,  including an amendment which would increase the aggregate number
of authorized shares of such class.

Approval of Certain Transactions

     Generally,  pursuant  to  each  of  Section  251 of the  DGCL  and  Section
7-111-103  of the CBCA,  an  affirmative  vote of a majority of the  outstanding
stock  entitled to vote thereon for the approval of any merger or  consolidation
is required.  Each of Section 251(f) of the DGCL and Section 7-111-103(7) of the
CBCA provide that unless required by the corporation's  charter,  no vote of the
holders of common stock of a  constituent  corporation  surviving  the merger is
required  for  certain  mergers  in  which  (i)  there  is no  amendment  to the
corporation's  charter, (ii) each share of stock of such corporation is to be an
identical  outstanding or treasury share of the surviving  corporation after the
effective date of the merger and (iii) either no stock or shares,  securities or
obligations  convertible  into  such  stock,  will be  issued  or  delivered  in
connection with the merger or the unissued shares or treasury shares of stock to
be issued or  delivered  in  connection  with the merger  plus  those  initially
issuable upon any  conversion of any other shares,  securities or obligations to
be issued or delivered under such plan are less than 20% of the shares of common
stock of such corporation outstanding immediately prior to the effective date of
the merger.

Preemptive Rights



                                       70
<PAGE>

     Neither  Delaware  law nor Colorado  law provide  preemptive  rights to the
holders of capital  stock.  Neither the PAI  Charter  nor PAI By-laws  contain a
provision  regarding  preemptive  rights.  Neither the Dencor Charter nor Dencor
By-laws contain a provision regarding preemptive rights.

Derivative Actions

     Derivative  actions  may be brought in Delaware  by a  stockholder,  and in
Colorado  by  a  shareholder,  on  behalf  of,  and  for  the  benefit  of,  the
corporation.  Section 327 of the DGCL provides  that a stockholder  must aver in
the complaint  that he was a stockholder  of the  corporation at the time of the
transaction of which he complains.  Section  7-107-402 of the CBCA provides that
no action  shall be  commenced by a  shareholder  in the right of a  corporation
unless the  plaintiff was a shareholder  of the  corporation  at the time of the
transaction  of which the plaintiff  complains or the plaintiff is a person upon
whom shares or voting trust certificates thereafter devolved by operation of law
from a person who was a shareholder at such time.

Dividends

     Subject   to  any   restrictions   in  a   corporation's   certificate   of
incorporation,  Section 170 of the DGCL generally provides that the directors of
a  corporation  may declare  and pay  dividends  out of surplus  (defined as the
excess if any,  of the net  assets  over  stated  capital)  or,  when no surplus
exists, out of net profits for the fiscal year in which the dividend is declared
and/or the preceding  fiscal year.  Dividends may not be paid out of net profits
if the stated capital of the  corporation  is less than the aggregate  amount of
stated capital  represented by the issued and  outstanding  stock of all classes
having a preference upon the  distribution of assets.  Section  7-106-401 of the
CBCA provides that the Board of Directors of a corporation  may  authorize,  and
the  corporation  may make,  distributions  to its  shareholders  subject to any
restriction  in the  articles  of  incorporation;  provided,  however,  that  no
distribution may be made if, after giving it effect:  (a) the corporation  would
not be able to pay its debts as they become due in the usual course of business;
or (b) the  corporation's  total  assets would be less than the sum of its total
liabilities  plus (unless the articles of  incorporation  permit  otherwise) the
amount that would be needed, if the corporation were to be dissolved at the time
of the  distribution,  to satisfy the  preferential  rights upon  dissolution of
shareholders  whose  preferential  rights are  superior to those  receiving  the
distribution.

Issuance  of Rights or Options to Purchase  Shares to  Directors,  Officers  and
Employees

     Under each of Section 157 of the DGCL and Section  7-106-205 of the CBCA, a
corporation is permitted, either in its charter or by resolution of the board of
directors, to create rights or options entitling the holders thereof to purchase
from the corporation any shares of its capital stock of any class or classes. In
the absence of actual fraud in the transaction, the judgment of the directors as
to the  consideration  for  the  issuance  of such  rights  or  options  and the
sufficiency thereof shall be conclusive.

Limitations on Directors' Liability

     Each of Section  102(b)(7)  of the DGCL and Section  7-108-402  of the CBCA
permit a  corporation  to include a  provision  in its  charter  eliminating  or
limiting  the  personal  liability  of a  director  to  the  corporation  or its
stockholders for damages for breach of the director's  fiduciary duty subject to
certain limitations.

     The PAI Charter  provides that a director will not be personally  liable to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director,  except (i) for any breach of the director's duty of loyalty
to the corporation or its  stockholders,  (ii) for acts or omissions not in good
faith or which involve  intentional  misconduct  or a knowing  violation of law,
(iii) for the unlawful payment of dividends or unlawful stock  repurchases under
Section 174 of the DGCL,  or (iv) for any  transaction  from which the  director
derived an improper personal benefit.


                                       71
<PAGE>


     The Dencor Charter does not contain a provision  regarding the  elimination
or limitation of the personal liability of a director.

     While these provisions provide directors with protection from liability for
monetary  damages for breaches of their duty of care, they do not eliminate such
duty.  Accordingly,  these provisions will have no effect on the availability of
equitable  remedies such as an  injunction  or rescission  based on a director's
breach of his or her duty of care.  The provisions  described  above apply to an
officer of the  corporation  only if he or she is a director of the  corporation
and is acting in his or her capacity as  director,  and do not apply to officers
of the corporation who are not directors.

Business Combination Statutes

     In  1988,   Delaware   enacted  a  statute  designed  to  provide  Delaware
corporations with limited  protection  against hostile  takeovers.  The takeover
statute,  which is  codified  in Section  203 of the DGCL  ("Section  203"),  is
intended to discourage  certain takeover  practices by impeding the ability of a
hostile acquiror to engage in certain transactions with the target company.

     In general,  Section 203 provides  that a person or entity that owns 15% or
more of the outstanding  voting stock of a Delaware  corporation (an "Interested
Stockholder")  may  not  consummate  a  merger  or  other  business  combination
transaction  with such  corporation  at any time  during the  three-year  period
following  the date  such  person or entity  became an  Interested  Stockholder,
unless  (i) prior to the date a person  became an  Interested  Stockholder,  the
board of directors  approved either the business  combination or the transaction
which resulted in the stockholder becoming an Interested Stockholder,  (ii) upon
consummation  of the transaction  that resulted in the  shareholder  becoming an
interested  shareholder,  the interested  shareholder  owned at least 85% of the
corporation's  outstanding  voting stock, with the number of shares  outstanding
calculated  without regard to those shares owned by the corporation's  directors
who are also officers or by certain employee stock plans, and (iii) any business
combination  with an  Interested  Stockholder  that is  approved by the board of
directors and by a two-thirds vote of the outstanding  voting stock not owned by
the Interested Stockholder.

     Colorado   has  not  enacted  a  statute   designed  to  provide   Colorado
corporations with limited protection against hostile takeovers.

Indemnification of Directors and Officers

     Section  145 of the DGCL  permits  a  corporation  to  indemnify  officers,
directors,  employees and agents for actions taken in good faith and in a manner
they reasonably  believed to be in, or not opposed to, the best interests of the
corporation,  and  with  respect  to any  criminal  action,  which  they  had no
reasonable  cause to  believe  was  unlawful.  The  DGCL  also  provides  that a
corporation  may  advance  expenses  of  defense  (upon  receipt  of  a  written
undertaking to reimburse the corporation if  indemnification is not appropriate)
and must  reimburse a successful  defendant for expenses,  including  attorney's
fees, actually and reasonably incurred, and permit a corporation to purchase and
maintain  liability  insurance for its directors and officers.  The DGCL further
provides that  indemnification may not be made for any claim, issue or matter as
to which a person has been adjudged by a court of competent jurisdiction,  after
exhaustion of all appeals  therefrom,  to be liable to the  corporation,  except
only to the extent a court  determines  that the person is entitled to indemnity
for such expenses that such court deems proper.



                                       72
<PAGE>

     Sections  7-109-102  and  7-109-107  of the CBCA  permit a  corporation  to
indemnify  officers,  directors,  employees and agents for actions taken in good
faith and in a manner they  reasonably  believe to be in, or not opposed to, the
best interest of the  corporation,  and with respect to criminal  action,  which
they had no  reasonable  cause to believe was  unlawful.  The CBCA also provides
that a  corporation  may advance  expenses of defense (upon receipt of a written
undertaking to reimburse the corporation if  indemnification is not appropriate,
and in the case of a director, a written affirmation of the directors good faith
belief  that  he  or  she  has  met  the   standard  of  conduct   required  for
indemnification)  and must  reimburse  the  successful  defendant  for expenses,
including  attorney's  fees,  actually  and  reasonably  incurred  and  permit a
corporation to purchase and maintain  liability  insurance for its directors and
officers.  The CBCA further  provides a corporation may not indemnify a director
in connection  with a proceeding by or in the right of the  corporation in which
the director was a judge liable to the  corporation,  or in connection  with any
other  proceeding  charging  that the  director  derived  in  improper  personal
benefit,  whether or not  involving  action in an  official  capacity,  in which
proceeding  the  director was a judge liable on the basis that he or she derived
an improper personal benefit.

     The PAI  By-laws  provide  that  any  person  who  was or is a party  or is
threatened to be made a party to any  threatened,  pending or completed  action,
suit or proceeding,  whether civil,  criminal,  administrative  or investigative
(other  than an action by or in the right of the  corporation)  by reason of the
fact  that  he  is or  was  a  director,  officer,  employee  or  agent  of  the
corporation,  or is or was  serving  at the  request  of  the  corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  shall be indemnified  by the  corporation
against expenses (including attorneys' fees), judgments,  fines and amounts paid
in settlement  actually and reasonably  incurred by him in connection  with such
action, suit or proceeding if the person acted in good faith and in a manner the
person reasonably  believed to be in or not opposed to the best interests of the
corporation,  and,  with respect to any criminal  action or  proceeding,  had no
reasonable cause to believe the person's  conduct was unlawful.  The termination
of any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption  that the person did not act in good faith and in a manner which the
person reasonably  believed to be in or not opposed to the best interests of the
corporation,  and,  with  respect  to any  criminal  action or  proceeding,  had
reasonable  cause to believe  that his  conduct  was  unlawful.  The PAI By-laws
provide further that the corporation  shall indemnify any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed  action or suit by or in the  right of the  corporation  to  procure a
judgment  in its  favor  by  reason  of the fact  that he is or was a  director,
officer,  employee  or agent of the  corporation,  or is or was  serving  at the
request of the corporation as a director,  officer, employee or agent of another
corporation,  partnership,  joint  venture,  trust or other  enterprise  against
expenses  (including  attorneys'  fees) actually and reasonably  incurred by the
person and in  connection  with the defense or settlement of such action or suit
if the person acted in good faith and in a manner the person reasonably believed
to be in or not opposed to the best interests of the corporation  except that no
indemnification  shall be made in respect  of any  claim,  issue or matter as to
which such  person  shall have been  adjudged  to be liable to the  corporation,
unless and only to the extent  that the Court of  Chancery  of  Delaware  or the
court in which such action or suit was brought shall determine upon  application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expense  which the Court of  Chancery of Delaware or such other court shall deem
proper. The rights to indemnification  and the advancement of expenses conferred
by the PAI  By-laws  are not  exclusive  of any  other  right  to which a person
seeking  indemnification  may be entitled under any by-law,  agreement,  vote of
stockholders  or  disinterested  directors or  otherwise.  PAI is  authorized to
purchase and maintain, insurance on behalf of its directors, officers, employees
and agents.

     Neither the Dencor Charter nor By-laws contain any provisions regarding the
indemnification of directors and officers.

Dissenters' Rights of Appraisal



                                       73
<PAGE>

     The DGCL generally entitles a stockholder to exercise appraisal rights upon
a merger or  consolidation of the corporation  effected  pursuant to the DGCL if
the stockholder  complies with the  requirements of Section 262 of the DGCL. The
CBCA generally entitles a shareholder to exercise appraisal rights upon a merger
or consolidation of the corporation  effected pursuant to the CBCA if the holder
complies with the requirements of Section 7-113-102 of the CBCA.  Because of the
structure of the Merger,  the  appraisal  rights  provisions of the DGCL and the
CBCA are not available to the holders of Dencor Common Stock in connection  with
the Merger.

                   CERTAIN PROVISIONS OF THE MERGER AGREEMENT

     The following is a summary of certain  provisions of the Merger  Agreement.
The following  summary  includes the material terms of such agreement but is not
necessarily complete and is qualified in its entirety by reference to the Merger
Agreement.

The Merger

     The Merger Agreement provides that,  following the approval and adoption of
the Merger  Agreement by the holders of PAI Common Stock and the approval of the
Charter  Amendments by the holders of Dencor Common Stock,  as described in this
Joint Proxy Statement/Prospectus,  Sub will be merged with and into PAI, and PAI
will continue as the Surviving Corporation.

     If the  conditions to the Merger are satisfied or waived,  the parties will
file  with the  Secretary  of State of the  State of  Delaware  a duly  executed
Certificate  of Merger,  and the Merger will become  effective at the  Effective
Time,  which will occur upon the filing and  acceptance  thereof or at such date
thereafter as is provided in the Certificate of Merger.

     Pursuant to the Merger  Agreement,  as of the Effective  Time, by virtue of
the Merger and without  any action on the part of any  stockholder  of PAI,  all
shares of PAI Common  Stock,  and any shares of PAI Common Stock owned by Dencor
or Sub will be cancelled and no capital  stock of Dencor or other  consideration
will be delivered in exchange therefor.

     Each share of PAI Common Stock issued and outstanding  immediately prior to
the Effective Time (other than shares to be cancelled)  will be converted at the
Exchange  Ratio into  validly  issued,  fully paid and  nonassessable  shares of
Dencor  Common Stock.  All such shares of PAI Common  Stock,  when so converted,
will no longer be outstanding  and will  automatically  be cancelled and retired
and each holder of a Certificate representing any such shares will cease to have
any rights with respect thereto,  except the right to receive certain  dividends
and other distributions upon the surrender of such Certificate.

     No certificates or scrip  representing  fractional  shares of Dencor Common
Stock will be issued upon the  surrender  for exchange of  Certificates,  and no
Dencor dividend or other  distribution or stock split or combination will relate
to any fractional  security,  and such fractional interests will not entitle the
owner thereof to vote or to any rights of a security  holder of Dencor.  In lieu
of any such fractional securities, each holder of shares of PAI Common Stock who
would  otherwise  have been  entitled to receive a fraction of a share of Dencor
Common Stock (after taking into account all shares of PAI Common Stock then held
of record by such  holder) will  receive  cash  (without  interest) in an amount
equal to the  product of such  fractional  part of a share of PAI  Common  Stock
multiplied by the Closing Price.

Representations and Warranties


                                       74

<PAGE>

     The Merger Agreement contains customary  representations  and warranties of
Dencor,  including,  among other things: (i) that the information to be included
herein and in the  Registration  Statement in connection with the Merger will be
free from  material  misstatements  and  omissions;  (ii) that there has been no
Material  Adverse  Change with  respect to Dencor,  except as  disclosed  in its
documents filed with the Commission; (iii) as to actions taken or not taken that
would jeopardize the  contemplated  tax and accounting  treatment of the Merger;
(iv) as to employment  agreements;  and (v) as to the Dencor Board of Directors'
actions with respect to the Merger Agreement, the Merger, the Charter Amendments
the Reverse Stock Split, and related matters. In addition,  the Merger Agreement
contains  representations  and  warranties  by  Dencor  as to its  organization,
capital structure,  authority to enter into the Merger Agreement and the binding
effect of the Merger Agreement on it.

Conduct of Business Pending the Merger

     Pursuant  to the Merger  Agreement,  Dencor and PAI have each  agreed  that
during the period from the date of the Merger  Agreement  through the  Effective
Time  (except  as  otherwise  specifically  required  by the terms of the Merger
Agreement),  it will, and it will cause its respective  subsidiaries  to, in all
material respects,  carry on their respective  businesses in the ordinary course
and consistent  with past practice and, to the extent  consistent  therewith and
with the terms of the Merger Agreement,  use all reasonable  efforts to preserve
intact their  current  business  organizations,  keep  available the services of
their  current  officers and  employees and preserve  their  relationships  with
customers,  suppliers and others having  business  dealings with them to the end
that their goodwill and ongoing  businesses  will be unimpaired at the Effective
Time.

Access to Information

     The  Merger  Agreement  provides  that,  subject to  applicable  provisions
regarding  confidentiality,  each of Dencor and PAI will, and will cause each of
its  subsidiaries  to, afford to the other  parties,  and to their  accountants,
counsel,  financial  advisers and other  representatives,  reasonable access and
permit them to make such  inspections as they may reasonably  require during the
period from the date of the Merger  Agreement  through the Effective Time to all
their respective properties, books, contracts, commitments and records.

Fees and Expenses

     Whether or not the Merger is  consummated,  except as described  below upon
certain terminations of the Merger Agreement, all costs and expenses incurred in
connection with the Merger Agreement and the transactions  contemplated  thereby
will be paid by PAI.

PAI Stock Options

     The Merger Agreement  provides that, no later than the Effective Time, each
PAI Stock Option which is  outstanding  immediately  prior to the Effective Time
pursuant to PAI's stock  option  plans will  become and  represent  an option to
purchase the number of shares of Dencor  Common Stock  (decreased to the nearest
full share)  determined  by  multiplying  (i) the number of shares of PAI Common
Stock subject to such PAI Stock Option  immediately  prior to the Effective Time
by (ii) the  Exchange  Ratio,  at an exercise  price per share of Dencor  Common
Stock  (rounded down to the nearest whole cent) equal to the exercise  price per
share of PAI Common Stock immediately prior to the Effective Time divided by the
Exchange  Ratio.  After the  Effective  Time,  except as  provided in the Merger
Agreement,  each new Dencor stock option issued in substitution  for a PAI Stock
Option will be exercisable upon the same terms and conditions as were applicable
under the related PAI Stock Option simultaneously with the Effective Time.

and cooperate with the other parties in doing, all things  necessary,  proper or
advisable to  consummate  and make  effective,  in the most  expeditious  manner
practicable,  the Merger and the other  transactions  contemplated by the Merger
Agreement and the prompt satisfaction of the conditions thereto.

Employment Agreements

     The  Merger  Agreement   provides  that  PAI  will  enter  into  employment
agreements with each of Maynard L. Moe,  President and a Director of Dencor, and
Theodore  A.  Hedman,  Vice  President  and a Director  of Dencor,  prior to the
Closing.

or the transactions contemplated thereby; provided that, in the case of any such
decree,  injunction  or  other  order,  each  of the  parties  shall  have  used

Merger is subject to the  fulfillment  at or prior to the Effective  Time of the

     The Merger  Agreement  may be terminated at any time prior to the Effective
Time,  whether before or after any approval by the  stockholders  of PAI: (i) by
mutual  written  consent of Dencor and PAI; (ii) by Dencor if (a) PAI shall have
failed to comply in any material respect with any of its covenants or agreements

five business days following receipt by PAI of notice of such failure to comply,

Meeting; (iv) by either Dencor or PAI if (a) the Merger has not been effected on
or prior to the close of business on December 31, 1997; provided,  however, that
the right to terminate the Merger Agreement pursuant to this clause shall not be
available  to any party whose  failure to fulfill any  obligation  of the Merger
Agreement  has been the cause of, or  resulted  in, the failure of the Merger to
have occurred on or prior to the  aforesaid  date, or (b) any court of competent
jurisdiction or any governmental, administrative or regulatory authority, agency
or body shall have issued an order,  decree or ruling or taken any other  action
permanently  enjoining,  restraining or otherwise  prohibiting the  transactions
contemplated  by the Merger  Agreement and such order,  decree,  ruling or other
action shall have become final and nonappealable; (v) by either Dencor or PAI if
there  has been (a) a  material  breach by the  other of any  representation  or

if the Board of Directors of PAI shall have recommended,  or shall have resolved
to recommend, to the stockholders of PAI any takeover proposal or offer for PAI;

shares  of PAI  Common  Stock  or  substantially  all of the  assets  of PAI for
consideration that provides  stockholders of PAI a value per share of PAI Common
Stock  which,  in the good  faith  judgment  of the Board of  Directors  of PAI,
provides a higher value per share than the  consideration  per share pursuant to
the Merger; or (ix) by Dencor, if a Third Party Acquisition occurs.

     In the event of  termination  of the Merger  Agreement by either  Dencor or
PAI,  the Merger  Agreement  shall  forthwith  become void and there shall be no
liability  hereunder  on the  part of PAI,  Dencor  or PAI or  their  respective
officers or directors, except as provided in the Merger Agreement.

     The Merger Agreement may be amended by the parties thereto,  by or pursuant
to action taken by their respective  Boards of Directors,  at any time before or
after  approval  of the Merger by the  stockholders  of PAI but,  after any such
approval by  stockholders  of PAI, no amendment  will be made which  changes the
Exchange  Ratio or which in any way materially  adversely  affects the rights of
such stockholders, without the further approval of such stockholders.


                                       77

<PAGE>

Waiver

     The Merger  Agreement  provides  that,  at any time prior to the  Effective
Time, the parties  thereto may (i) extend the time for the performance of any of
the  obligations  or other  acts of the other  parties  thereto,  (ii) waive any
inaccuracies in the  representations  and warranties  contained herein or in any
document  delivered  pursuant thereto and (iii) waive compliance with any of the

                   SECURITIES AND EXCHANGE COMMISSION POSITION
                           ON CERTAIN INDEMNIFICATION

     Each of the DGCL and the CBCA provide for  indemnification by a corporation
of costs  incurred by directors,  employees,  and agents in  connection  with an
action,  suit, or proceeding  brought by reason of their position as a director,
employee,  or agent. The person being  indemnified must have acted in good faith
and in a manner  he  reasonably  believed  to be in or not  opposed  to the best
interests of the corporation.

     The Board of  Directors  of each of Dencor  and PAI are  empowered  to make
other  indemnification as authorized by each corporation's  respective  Charter,
By-laws or corporate  resolution  so long as the  indemnification  is consistent
with the DGCL or CBCA, as applicable.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Dencor or
PAI pursuant to the foregoing  provisions,  or  otherwise,  the Company has been
advised  that in the opinion of the  Securities  And  Exchange  Commission  such
indemnification  is against public policy as expressed in the Securities Act and
is therefore, unenforceable.

                                     EXPERTS

     The financial  statements  of Dencor for the years ended  December 31, 1996
and  1995  have  been  audited  by  Gelfond  Hochstadt  Pangburn  &  Co.  (GHP),
independent  auditors, as set forth in their report thereon included therein and
incorporated  herein by reference.  Such financial  statements are  incorporated
herein by  reference in reliance  upon such report  given upon the  authority of
such firm as experts in accounting and auditing.  GHP's report dated January 24,
1997 contains an  explanatory  paragraph  that states that Dencor has reported a
net loss for the year ended  December 31, 1996 and has a  shareholders'  deficit
and working  capital  deficiency  as of December 31, 1996,  these  factors raise
substantial  doubt about Dencor's  ability to continue as a going  concern.  The
financial  statements do not include any adjustments  that might result from the
outcome of that uncertainty.

     Representatives  of Gelfond  Hochstadt  Pangburn & Co. are  expected  to be
present at the Dencor Special  Meeting,  where they will have the opportunity to
make a  statement  if they desire to do so and will be  available  to respond to
appropriate questions.

     The  consolidated  financial  statements of PAI as of December 31, 1995 and
December  31,  1996  have been  audited  by KPMG Peat  Marwick  LLP  independent
auditors,   as  set  forth  in  their  report  thereon  included  therein.  Such
consolidated  financial  statements  are  incorporated  herein by  reference  in
reliance  upon such report  given upon the  authority of such firm as experts in
accounting  and  auditing.  KPMG's  report  dated  June  27,  1997  contains  an
explanatory  paragraph that states that PAI has suffered  recurring  losses from
operations and has a net capital deficiency, which raise substantial doubt about
its  ability  to  continue  as  a  going  concern.  The  consolidated  financial
statements do not include any adjustments  that might result from the outcome of
that uncertainty.

     Representatives  of KPMG Peat Marwick LLP are expected to be present at the
PAI Special Meeting, where they will have the opportunity to make a statement if
they desire to do so and will be available to respond to appropriate questions.

                                 LEGAL OPINIONS

     The  legality  of the Dencor  Common  Stock being  offered  hereby is being
passed upon for Dencor by Bearman Talesnick & Clowdus Professional  Corporation,
counsel to Dencor.

                   OTHER INFORMATION AND STOCKHOLDER PROPOSALS

     Dencor  management  and PAI  management  know of no other  matters that may
properly  be, or which are  likely to be,  brought  before  the  Dencor  Special
Meeting or the PAI Special Meeting, respectively.  However, if any other matters
are properly  brought  before such Special  Meetings,  the persons  named in the
enclosed proxy or their substitutes will vote the proxies in accordance with the

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

Board of Directors and Shareholders
Dencor Energy Cost Controls, Inc.
Denver, Colorado

We have audited the  accompanying  balance sheet of Dencor Energy Cost Controls,
Inc.  (the  Company) as of December  31,  1996,  and the related  statements  of
operations,  shareholders' equity (deficit) and cash flows for each of the years
in the two-year period ended December 31, 1996.  These financial  statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial  position of Dencor Energy Cost Controls,
Inc. as of December 31,  1996,  and the results of its  operations  and its cash
flows for each of the years in the two-year  period ended  December 31, 1996, in
conformity with generally accepted accounting principles.

The  accompanying  financial  statements  have been  prepared  assuming that the
Company  will  continue  as a  going  concern.  As  discussed  in  Note 2 to the
financial statements, the Company reported a $74,400 net loss for the year ended
December 31, 1996, and a shareholders'  deficit and a working capital deficiency
of $11,300 and $16,700,  respectively,  as of December 31, 1996.  These  factors
raise  substantial  doubt  about the  Company's  ability to  continue as a going
concern.  Management's  plans in regard to these  matters are also  described in
Note 2. The  financial  statements  do not  include any  adjustments  that might
result from the outcome of this uncertainty.

                     YEARS ENDED DECEMBER 31, 1996 AND 1995



1.  Organization and significant accounting policies:

     Organization:

     Dencor Energy Cost Controls,  Inc. (the Company)  manufactures  and markets
     electrical  energy  cost  control  devices  and  equipment  which  are sold
     primarily  to  distributors  and  dealers in the United  States and Canada.
     There is only one business segment.

     Inventories:

     Inventories are stated at the lower of cost (first-in,  first-out; FIFO) or
     market.

     Furniture, equipment, and depreciation:

     Furniture and equipment are stated at cost.  Depreciation is computed using
     the  straight-line  method over the  estimated  useful lives of the related
     assets of three to five years.

     Research and development:

     Research and development costs are charged to operations as incurred.

     Product warranties:

     Estimated costs related to product  warranties are provided for at the time
     of sale.

     Earnings (loss) per share:

     Earnings  (loss)  per common  share is  computed  based  upon the  weighted
     average number of common shares outstanding during the period.

     Accounting for income taxes:

     Deferred  tax  assets and  liabilities  are  recognized  for the future tax
     consequences  attributable to differences  between the financial  statement
     carrying  amounts of existing assets and  liabilities and their  respective
     tax bases.  Deferred tax assets and  liabilities are measured using enacted
     tax rates  expected to apply to taxable  income in the years in which those
     temporary  differences are expected to reverse.  The effect on deferred tax
     assets and liabilities of a change in tax rates is recognized in the state-
     ment of operations in the period that includes the enactment date.

                       YEARS ENDED DECEMBER 31, 1996 AND 1995



1.  Organization and significant accounting policies (continued):

     Use of estimates in the preparation of financial statements:

     The  preparation  of financial  statements  in  conformity  with  generally
     accepted  accounting  principles  requires management to make estimates and
     assumptions  that affect the reported amounts of assets and liabilities and
     disclosure  of  contingent  assets  and  liabilities  at  the  date  of the
     financial  statements  and the  reported  amounts of revenues  and expenses
     during the  reporting  periods.  Actual  results  could  differ  from those
     estimates.

     Recently issued accounting standards:

     Management does not believe that any recently issued  accounting  standards
     will have a material impact on the Company's  financial position or results
     of operations.

2.  Going concern, results of operations, and management's plans:

     The Company's  financial  statements  for the year ended  December 31, 1996
     have  been  prepared  on a going  concern  basis,  which  contemplates  the
     realization of assets and the settlement of liabilities  and commitments in
     the normal course of business.  For the year ended  December 31, 1996,  the
     Company  reported  a $74,400  net loss and a  shareholders'  deficit  and a
     working  capital  deficiency  of  $11,300  and  $16,700,  respectively,  at
     December  31,  1996.  The  Company  has  also  experienced  difficulty  and
     uncertainty in meeting its liquidity needs. These factors raise substantial
     doubt about the Company's ability to continue as a going concern.

     The Company's 1997 operating plan includes achieving  increased sales goals
     and maintaining  its cost reduction  program,  which  primarily  includes a
     reduction in labor costs.  Management believes that actions presently being
     taken  under its 1997  operating  plan will  enable the  Company to achieve
     profitability  during 1997.  The  financial  statements  do not include any
     adjustments that might be necessary if the Company is unable to continue as
     a going concern.

3.  Note receivable:

     The note receivable is due on demand from a customer, bears interest at 18%
     and is unsecured.

                                                                  =========

     The elements of cost in inventories include materials, labor and overhead.

5.  Notes payable - shareholders:

     The notes payable to shareholders  are unsecured,  due on demand,  and bear
     interest at 12% to 18.25% per year.  The weighted  average  interest  rates
     during the years ended December 31, 1996 and 1995 were approximately  18.4%
     and 17.3%,  respectively.  Interest  expense of  approximately  $18,400 and
     $17,100  associated  with these notes payable was charged to operations for
     the years ended December 31, 1996, and 1995, respectively.

                     YEARS ENDED DECEMBER 31, 1996 AND 1995





8.   Common stock:

     At December 31, 1996,  the Company has  reserved  196,000  shares of common
     stock for issuance  under a restricted  stock bonus plan. All employees and
     directors of the Company, with the exception of the President, are eligible
     to receive stock bonuses under this plan.  There have been no shares issued
     under this plan.

9.   Concentration of credit risk:

     The  Company  extends  credit  based  on an  evaluation  of the  customer's
     financial condition,  generally without requiring  collateral.  Exposure to
     losses on receivables is principally dependent on each customer's financial
     condition.  The  Company  monitors  its  exposure  for  credit  losses  and
     maintains allowances for anticipated losses.

     During 1996, two customers  accounted for approximately 23%, and 21% of net
     sales.  During 1995, four customers  accounted for approximately  12%, 13%,
     14% and 22% of net sales.  As of December  31, 1996,  60% of the  Company's
     accounts receivable were due from three customers.

     The Company's export and domestic sales consist of the following:

                                            Years ended December 31,
                                            1996               1995
                                          ---------         ---------

        Net sales, Canada                 $     500         $  88,000
        Net sales, United States            388,200           479,900
        Total net sales                   $ 388,700         $ 567,900


10.    Fair value of financial instruments:

       The carrying  values of the Company's  financial  instruments,  including
        cash, receivables, accounts payable and accrued liabilities, approximate
        fair  values  primarily   because  of  the  short  maturities  of  these
        instruments.  The fair  values  of  notes  due to  shareholders  are not
        practicable  to estimate,  due to the  indefinite  payment  terms of the
        amounts,  and  due  to  the  related  party  nature  of  the  underlying
        transactions.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS

A. The condensed Financial  Statements included herein have been prepared by the
Company,  without audit, pursuant to the rules and regulations of the Securities
and Exchange  Commission.  Certain information and footnote disclosures normally
included in financial  statements prepared in accordance with generally accepted
accounting  principles have been condensed or omitted pursuant to such rules and
regulations,  although the Company believes that the disclosures are adequate to
make the information presented not misleading.

     In the  opinion  of  the  Company,  all  accompanying  unaudited  condensed
Financial  Statements  contain all adjustments,  which consist only of recurring
adjustments,  necessary to present fairly the financial position as of March 31,
1997,  and the results of  operations  and cash flows for the three months ended
March 31, 1997 and 1996.

     The results of operations for the three-month  periods ended March 31, 1997
and 1996, are not  necessarily  indicative of the results to be expected for the
full year. It is suggested that these Condensed Financial  Statements be read in
conjunction with the Financial  Statements and the notes therein included in the
Company's latest annual report on Form 10-KSB.

B. Long-Term Debt:

     As of the end of First Quarter, 1997, the Company had no long-term debt.

C. Common Stock:

     During the First Quarter, 1997, the Company sold no restricted stock.

                          Independent Auditors' Report



The Board of Directors and Shareholders
Proven Alternatives, Inc.:

We  have  audited  the  accompanying   consolidated  balance  sheets  of  Proven
Alternatives,  Inc. and  subsidiaries  as of December 31, 1996 and 1995, and the
related consolidated  statements of operations,  shareholders'  deficit and cash
flows for the years then ended. These consolidated  financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects, the financial position of Proven Alternatives,
Inc. and subsidiaries as of December 31, 1996 and 1995, and the results of their
operations  and their cash flows for the years  then  ended in  conformity  with
generally accepted accounting principles.

The accompanying  consolidated  financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in note 1 to the
consolidated  financial  statements,  the Company has suffered  recurring losses
from  operations  and has current  liabilities in excess of current assets and a
shareholders'  deficit at December  31,  1996 and 1995 that  raises  substantial
doubt about its ability to continue as a going  concern.  Management's  plans in
regard to these matters are also described in note 1. The consolidated financial
statements do not include any adjustments  that might result from the outcome of
this uncertainty.

                   Notes to Consolidated Financial Statements

                           December 31, 1996 and 1995


(1) Business

     Proven  Alternatives,  Inc. (the Company) was  incorporated in April,  1991
     under the laws of the state of California.  It was reincorporated under the
     laws of the  state  of  Delaware  in  November,  1991.  The  Company  is an
     integrated  energy  management  firm whose  goal is to  enhance  customers'
     shareholder  values through  long-term service  relationships.  It provides
     process  knowledge,  energy  management  capabilities,   energy  efficiency
     technologies,  and capital capabilities to solve business problems relating
     to energy usage and industrial  process  improvement.  The Company provides
     its  services in six service  areas:  total  energy  management,  strategic
     consulting, program management,  merchant banking capital services (through
     its  subsidiary,   Proven  Alternatives  Capital  Corp.  ("PACC")),  energy
     procurement,  and energy  information  services.  Typically,  services  are
     provided  by the  Company as a  long-term  partner  with the  customer on a
     performance  basis. The Company's  services include the  identification  of
     underperforming corporate assets, the recommendation for and application of
     processes,  equipment,  and techniques to improve the  performance of these
     assets and financing of these projects. The Company markets its services to
     companies  which could benefit  significantly  from  improvements in energy
     procurement  and use and to those whose  operations  are  energy-intensive.
     These clients are located in the United States with plans to expand abroad.

     In 1996,  management  decided to reengineer the marketing  direction of the
     Company  toward  large  programs and energy  management  rather than single
     projects.  Management  recognized that this  reengineering  would adversely
     affect results in the near-term, and believes the shift in marketing of the
     Company's  programs  and  processes  is now leading to the  development  of
     long-term strategic  relationships that are taking shape in 1997. While the
     fundamental  services and technologies offered by the Company have remained
     largely the same,  the emphasis on programs (as compared to sales of single
     projects),  on production  enhancements in the industrial  sector,  and the
     integration  of services into customer  solutions is now seen by management
     as the most effective manner to develop the Company's core business.

     As shown in the accompanying consolidated financial statements, the Company
     has incurred losses and negative cash flows from operations at December 31,
     1996.  The Company's  future  success and economic  viability will directly
     relate to achieving profitable  operations,  managing tight liquidity,  and
     continuing to develop capital resources.

     The Company  anticipates meeting liquidity needs through growth in business
     and  non-recourse  financing  of  long-term  receivables  and  infusion  of
     additional  equity.  Based  on  methods  described  in Note  4,  management
     estimates the present value of the Company's long-term  receivables exceeds
     book  value  by  approximately  $6.9  million  as  of  December  31,  1996.
     Additionally,  the  Company  expects  to raise  capital  through  a private
     offering of preferred stock to be completed in the latter part of 1997. The
     Company has executed a Letter of Intent and is  finalizing  an agreement to
     complete a reverse merger with Dencor Energy Cost Controls,  Inc., a public
     company based in Denver. The shareholders of Proven  Alternatives will hold
     a substantial majority of the merged public company,  which will be renamed
     Proven Alternatives, Inc. Management anticipates completing the transaction
     in the latter half of 1997.

                                                                     (Continued)

(2) Summary of Significant Accounting Policies

     (a) Principles of Consolidation

     The  consolidated  financial  statements  include  the  accounts  of Proven
     Alternatives,  Inc. and its wholly  owned  subsidiaries.  All  intercompany
     account balances, transactions and profits have been eliminated.

     (b) Reclassifications and Accounting Corrections

     Certain  reclassifications have been made to the 1995 amounts to conform to
     the 1996 presentation.

     Accumulated  deficit as of December  31, 1994 has been  restated to reflect
     revisions of tax accruals.

     (c) Management Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
     accepted  accounting  principles  requires management to make estimates and
     assumptions  that affect the reported amounts of assets and liabilities and
     disclosure  of  contingent  assets  and  liabilities  at  the  date  of the
     financial  statements,  and the  reported  amounts of revenue and  expenses
     during  the  reporting  period.  Actual  results  could  differ  from those
     estimates.

     (d) Impairment

     If the Company  concludes  that the recovery of the  carrying  amount of an
     asset is  permanently  impaired,  it reduces  such  carrying  amount to the
     estimated fair value of the asset.

     As energy savings contracts  representing  individual  customers are pooled
     under a common  utility  program,  impairment of energy savings and finance
     receivables is assessed on a program by program basis.

     (e) Revenue and Cost Recognition

     The Company  earns  revenue  from  various  services.  These can be broadly
     described as follows:

          (i) Project Sales

               Project  sales  represent  revenues  generated  from sales  under
               contracts to design,  supply and install process  improvement and
               energy  efficiency  projects.  Revenues  and  cost of  sales  are
               recognized  using the completed  contract  method.  A contract is
               accepted  as  completed  once  process,  energy,  and  collateral
               savings  have  been  measured,   verified  and  accepted  by  the
               customer.

               When project sales are financed,  the Company records the project
               sale and a  corresponding  energy savings and finance  receivable
               equal to the implicit or contractual  sales price of the project.
               The related project costs are charged to cost of sales.


                                                                     (Continued)
                                      F-22
<PAGE>

                                        

                   PROVEN ALTERNATIVES, INC. AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements


          (ii) Energy Savings and Finance Revenues

               Payments  under  energy  savings  agreements  are based on actual
               energy  savings and are  structured to recover the energy savings
               and finance  receivable,  provide for monitoring and  maintenance
               costs and generate an equity return to the Company on the portion
               of the purchase  price not  financed by  non-recourse  debt.  The
               implicit  cost of capital  rate for the financed  transaction  is
               used  to  record   recovery   of  energy   savings   and  finance
               receivables.  Payments  received in excess of amounts  applied to
               the  recovery  of energy  savings  and  finance  receivables  are
               reflected as energy savings and finance revenues as received.

          (iii) Professional Service Fees

               Professional   service   fees  earned   represent   payments  for
               consulting,  management, and design services. Fees are recognized
               as the services are performed.

          (iv) Monitoring and Maintenance

               As part of certain energy service  contracts,  the Company agrees
               to  monitor  and  maintain  the  equipment  for a period of time,
               usually  the  contract  term.  An  estimate  for  monitoring  and
               maintenance  cost  recovery  and profit  thereon is  included  in
               determining  project  pricing.  A portion  of the  project  sales
               revenue is deferred upon  recognition  of the sale to provide for
               monitoring  and  maintenance   obligations.   The  allowance  for
               monitoring and maintenance is established based on an estimate of
               actual  costs  to be  incurred  together  with  a  normal  profit
               thereon. The allowance is amortized to income over the respective
               terms  of  the  individual   contracts.   Actual  monitoring  and
               maintenance costs are expensed as incurred.

          (v) Cost of Sales

          Cost of sales includes all direct materials and labor costs related to
          contract  performance plus an allocation of indirect overhead costs in
          the project. The indirect overhead costs are allocated based on direct
          labor.  Costs incurred  during the performance of the contract and any
          amounts  billed or received are offset against each other and reported
          as  deferred  items  in the  balance  sheet  until  completion  of the
          contract. A provision for estimated losses on uncompleted contracts is
          made in the  period in which such  losses  become  determinable.  Upon
          completion of a contract, the deferred billings and costs are recorded
          as revenues and cost of sales, respectively.

     (f) Property and Equipment

          Property and equipment are carried at cost, or in the case of business
          combinations  accounted  for under the purchase  method,  at estimated
          fair market values. Depreciation is provided for over the useful lives
          (three to seven years) of the related  assets using the  straight-line
          method.  The cost of maintenance  and repairs is charged to expense as
          incurred; significant renewals and betterments are capitalized.

                                                                     (Continued)

     (g) Intangible Assets

          Intangible  assets  include  goodwill,  covenants  not to compete  and
          organizational  costs.  Goodwill  represents the cost in excess of the
          fair value of the net assets acquired in business  combinations and is
          amortized on a straight-line basis over seven to ten years.  Covenants
          not to compete are  recorded at cost and  amortized  over the lives of
          the agreements using the straight-line  method.  Organizational  costs
          represent costs incurred  relating to the establishment of the Company
          and are amortized over five years using the straight-line method.

          Amortization  expense of the intangible assets,  including a writedown
          of  $129,016   associated   with  the   acquisition   of  one  of  the
          subsidiaries,  amounted to $302,282  and  $325,637 for the years ended
          December 31, 1996 and 1995, respectively.

     (h) Income Taxes

          Income taxes are  computed  under  Statement  of Financial  Accounting
          Standards  (SFAS) 109.  Under the asset and  liability  method of SFAS
          109,   deferred  income  taxes  are  recognized  for  the  future  tax
          consequences   attributable  to  differences   between  the  financial
          statement  carrying  amounts of existing  assets and  liabilities  and
          their  respective tax bases.  Deferred tax assets and  liabilities are
          measured  using enacted tax rates  expected to apply to taxable income
          in the years in which those  temporary  differences are expected to be
          recovered or settled.  Under SFAS 109, the effect on deferred taxes of
          a change in tax rates is  recognized  in  income  in the  period  that
          includes the enactment  date.  The provision for income taxes includes
          deferred taxes which result from  temporary  differences in accounting
          for financial  statement and tax purposes using the liability  method,
          and from  differences  between  the fair value of assets  acquired  in
          business combinations accounted for as purchases and their tax bases.

          Deferred  tax  assets  are   recognized   for   deductible   temporary
          differences  and operating  loss and tax credit  carryforwards,  after
          which a valuation allowance is established to reduce that deferred tax
          asset if it is "more  likely than not" that the  related tax  benefits
          will not be realized.

          Management has evaluated the deferred tax asset  recognized under SFAS
          109 and has  established a valuation  allowance for the portion of the
          deferred  tax  asset  that does not meet the  "more  likely  than not"
          recognition  criteria,  since all deductible temporary differences may
          not be offset  against  taxable  temporary  differences  and  expected
          future  taxable  income.  Accordingly,  management  has  established a
          valuation  allowance of $5,983,566  and  $4,278,905 as of December 31,
          1996 and 1995 to reduce the  deferred  tax asset to the amount that is
          more likely than not to be realized.


                                                                     (Continued)

                   Notes to Consolidated Financial Statements

     (i) Concentration of Credit Risk

          The Company has entered into certain long-term  performance  contracts
          with  various  utilities  located  in the  eastern  United  States and
          California.  Under these long-term performance contracts,  the Company
          delivers  energy  savings for which the utilities are required to pay,
          on a  kilowatt  saved  basis.  Each of the  utilities  have met  their
          obligations to the Company under these long-term performance contracts
          to date.  Management  does not currently  foresee any of the utilities
          being unable to meet their future obligations.  Under these contracts,
          if the total actual  energy  savings are less than a minimum  delivery
          level established within the contract,  the Company may be required to
          compensate  the  utility  for the short  fall.  At current  production
          levels management does not foresee any such obligations.

          Financial   instruments  which  potentially  subject  the  Company  to
          concentrations  of  credit  risk  consist  principally  of the  energy
          savings and finance  receivables.  During 1996 and 1995, the Company's
          finance  receivables were  concentrated in the pulp and paper industry
          located  on the east  coast of the  United  States.  The  Company  had
          approximately  $15,200,000  and  $17,100,000  of  energy  savings  and
          finance  receivables  from pulp and paper customers and  approximately
          $18,067,000  and  $15,300,000  of  associated  non  recourse  debt  at
          December 31, 1996 and 1995,  respectively.  In addition,  one customer
          accounted  for  approximately   $12,600,000  and  $14,261,000  of  the
          Company's energy savings and finance  receivables at December 31, 1996
          and 1995,  respectively.  The  Company  performs  ongoing  credit  and
          business evaluations of its customers.

(4) Energy Savings and Finance Receivables

          Energy savings and finance  receivables  consist of amounts receivable
          pursuant to long-term energy savings  contracts.  Customer and utility
          payments  are  based on a  percentage  of the  actual  energy  savings
          achieved.


                                                                     (Continued)

          Cash  receipts  from  energy  savings  and  finance   receivables  are
          exceeding  original  projections  for  certain  projects.   Management
          estimates the present value of these  receivables to be  approximately
          $29.9  million as of December  31, 1996,  which  exceeds book value of
          these  receivables  by  approximately  $6.9 million.  This estimate is
          based on  average  billings  in 1996,  assumes  that  such  levels  of
          performance  will be sustained for the remaining  term of the project,
          and uses a 16% discount factor.

          Customer  payments  are  based  on  a  percentage  of  energy  savings
          realized.  Anticipated principal payments for the years ended December
          31 are as follows:

          The Company  has pledged  energy  savings and finance  receivables  as
          collateral to secure non recourse debt.

(5) Work in Progress and Pre-contract Cost

          Work in  progress  includes  direct  labor and  materials  related  to
          projects,  plus  an  allocation  of  indirect  overhead  costs.  These
          indirect overhead costs are allocated based on direct labor.

          Costs associated with proposal  preparation,  net of a reserve for the
          estimated   costs  of   non-recoverable   costs,   are   reflected  in
          pre-contract costs. This reserve is based on the Company's  historical
          percentage of pre-contract activity resulting in successful contracts.
          Pre-contract costs consisted of the following as of December 31:

                   PROVEN ALTERNATIVES, INC. AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements

     The  Company,  in  conjunction  with the 1992  acquisition  of Puget Energy
     Services,  Inc.,  issued  a  promissory  note  with a  principal  value  of
     $2,000,000 to Puget  Western,  Inc. In 1993 the note payable  agreement was
     amended  to  include  accrued  interest,  increasing  the loan  balance  to
     $2,192,819.  In  1996,  the note  was  again  amended  to  include  accrued
     interest, increasing the loan balance to $2,224,324. Quarterly payments for
     the years 1996 and 1995, varied from $50,000 to approximately $90,000, with
     a final payment of $1,389,035 due on December 31, 1998. The note carries an
     interest  rate of 8.5% per annum.  Forty-nine  percent  of the PACC  common
     stock has been pledged as a security interest to Puget Western, Inc.

     At December 31, 1996 and 1995, the Company had a $3,000,000  line of credit
     with U.S.  Bank of  Washington  at an interest  rate of prime plus 0.5% per
     annum  (8.75% and 9% as of December  31, 1996 and 1995,  respectively).  In
     March  1997  this  line was  replaced  by a line of  credit  of  $4,000,000
     provided by Silicon  Valley  Bank of Santa  Clara,  California,  to provide
     working capital and letters of credit.  The initial use of the facility was
     to repay the  outstanding  indebtedness  owed to U.S.  Bank.  Both  banking
     arrangements  were  secured by the pledge of  160,000  shares of  CalEnergy
     Company,  Inc. by a significant  shareholder  as well as the  shareholder's
     personal guarantee.

     The long-term  borrowing  arrangements  include  covenants and  performance
     requirements which must be met or must be waived by the lender. The Company
     has complied with or obtained  waivers where  appropriate for all instances
     of non compliance.

(9) Non Recourse Debt

     (a) Senior Debt

     In June 1996,  PACC  replaced  its $15  million  non  recourse  Senior Debt
     Facility  with  another  institution  (Senior  Lender).  The  new  facility
     includes  a non  recourse  Senior  Term  Debt  Loan  and two  non  recourse
     Subordinated  Term Debt Loans. As of December 31, 1996, PACC had $5,316,703
     outstanding  under the Senior  Debt Loan  maturing  on  September  1, 2002.
     Interest  on the  Senior  Debt Loan is fixed at 12.3%,  with  monthly  loan
     payments which vary from $51,000 to $172,000.

     Project  receipts  are  collected  in a lockbox  controlled  by the  Senior
     Lender.  Debt service is paid  monthly  from the lockbox,  with excess cash
     being  remitted to the  Company.  At  December  31,  1996,  the Company had
     approximately $426,000 cash in the lockbox.

     In 1996,  PACC negotiated an additional  Senior Debt Facility  (Senior Debt
     II) to finance the long term receivables due under another of the Company's
     utility  demand  side  management  programs.  The  Company  had  $2,394,104
     outstanding  under the Senior Debt II Facility  as of  December  31,  1996,
     maturing on December 15,  2003.  Interest on the Senior Debt II Facility is
     fixed at 11.5%, with monthly loan payments of $41,583.

                                                                     (Continued)

                   PROVEN ALTERNATIVES, INC. AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements

     Prior to June  1996,  PACC had a  facility  with a bank in the form of term
     advances  to be made  from  time to time as new  projects  were  completed,
     subject to bank approval. PACC had $6,477,418 outstanding under this Senior
     Debt facility as of December 31, 1995.  Interest on the outstanding portion
     of the first  $3,610,000  of the facility was fixed under an interest  rate
     swap agreement. Interest on the remaining principal was at a variable rate,
     to be  either  (a) the base  rate  plus the  applicable  margin  or (b) the
     Eurodollar  rate plus the applicable  margin,  at the option of the Company
     (8.22% as of December  31,  1995).  PACC  recorded a net benefit  from this
     arrangement  of  approximately  $24,000 as a reduction in interest  expense
     during 1995.  The facility  provided for monthly term loan  payments  which
     varied  from  approximately  $79,000  to  $130,000  over  the  life  of the
     facility.  PACC was  required to maintain a debt  service  reserve  against
     potential  shortfalls  of future cash flows from the projects  securing the
     Senior Debt borrowings from the bank.  Payments into the reserve were based
     on a formula  defined in the agreement and varied monthly  depending on the
     amount of projects funded. In addition,  the bank required a commitment fee
     of 0.625% per annum on the average  daily unused  commitment  as well as an
     agency fee of  $125,000  per  annum.  During  1996 and 1995,  approximately
     $22,000 and $59,000 in commitment fees were paid to the bank.

     Assets  financed under Senior Debt  facilities are held by special  purpose
     entities.  Security  interests  have been  granted to the  lenders in these
     entities' assets.

     (b) Subordinated Debt

     The new Senior Debt  Facility,  organized in June 1996,  also  includes two
     Subordinated  Term Debt Loans (I and II). As of December 31, 1996, PACC had
     $1,065,463  and $2,450,000  outstanding  under the  Subordinated  Term Debt
     Loans I and II,  respectively.  Subordinated  Term Debt  Loan I matures  on
     September 1, 2002 and bears an interest  rate of 16.8%.  Subordinated  Term
     Debt Loan II matures on December  31,  1999 and bears an  interest  rate of
     16.15%.  Payments  on the  Subordinated  Term Debt Loans are made  monthly,
     varying from $1,000 to $120,000.

     During 1994,  PACC  negotiated an additional  non recourse  facility with a
     non-regulated  subsidiary  of a utility  (Subordinated  Lender) of up to $5
     million  (Subordinated  Debt), in the form of term advances to be made from
     time to time as new  projects  are  completed,  subject to  approval by the
     lender of the Senior Debt.  PACC had $3,332,701 and $3,460,642  outstanding
     under this  Subordinated  Debt  facility as of December  31, 1996 and 1995,
     respectively.  The facility  provides for monthly term loan payments  which
     will vary from approximately $16,000 to $150,000. The amount outstanding at
     December 31, 1996 is due on August 31, 2002. The interest rate on the first
     $2,000,000  is 25%,  declining in stages to 21% for amounts in excess of $4
     million.

     (c) Other Non Recourse Debt

     Additionally,  PACC has another non recourse facility for 100% financing of
     qualified  projects  providing  for monthly  payments  which will vary from
     approximately $197,000 to $223,000 over the life of the facility.  PACC had
     $10,356,891 and $10,103,164  outstanding under this facility as of December
     31,  1996 and  1995,  respectively.  The  facility  is due June 1, 2003 and
     carries  interest  at a rate  between  13% and 15% per  annum,  varying  by
     project.

                                                                     (Continued)

     PACC also has a non recourse  installation loans facility under this credit
     facility on a project by project  basis.  PACC had $658,262 and  $1,099,230
     outstanding under the installation  loan facility,  which bears interest at
     15% per annum, as of December 31, 1996 and 1995, respectively.  The Company
     has granted a security  interest in certain of its host customer  contracts
     and all equipment and materials to be installed under the contracts.

     The increase in the valuation  allowance from December 31, 1995 to December
     31, 1996 is due primarily to  assessment of the recovery of the  receivable
     in accordance with SFAS 109.

     Income tax expense was $10,983 and $10,204 for the years ended December 31,
     1996 and 1995  respectively,  and  differed  from the  amounts  computed by
     applying the U.S. federal income tax rate of 34 percent to pretax loss as a
     result of the following at December 31:

     net operating loss carryforwards of approximately $35,000,000 expiring from
     2006 through 2011.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements

     For  California  income tax purposes,  as of December 31, 1996, the Company
     has net operating loss carryforwards of approximately  $14,000,000 expiring
     from 1997 through  2001.  The  difference  between the net  operating  loss
     carryforward for federal income tax purposes and for California  income tax
     purposes  results  generally from a 50%  limitation on the California  loss
     carryforwards  and the  suspension  of loss  utilization.  In  addition,  a
     portion of the federal loss is apportioned to states other than California.

(11) Lease Commitments

     The Company  leases office  facilities,  equipment,  machines and furniture
     under operating leases expiring through June 1998. Rent expense, recognized
     over the terms of the leases, was $379,114 and $622,582 for the years ended
     December 31, 1996 and 1995,  respectively.  Future  minimum  payments under
     non-cancelable  operating  leases for the years  ending  December 31 are as
     follows:

(12) Related Party Transactions

     An officer and  significant  shareholder  accepted  notes  payable from the
     Company which had $37,551 outstanding as of December 31, 1995.

     At December 31, 1996 and 1995,  certain borrowings of the Company amounting
     to  approximately  $2,434,878  and  $2,336,289,  respectively,  and certain
     facilities leases were guaranteed by a significant  shareholder who pledged
     personal  assets  as  security.   In  addition,   the  Company  had  issued
     approximately $264,000 of standby letters of credit as of December 31, 1996
     and 1995, which, as part of the Line of Credit, were personally  guaranteed
     by the significant  shareholder.  For the years ended December 31, 1996 and

     respectively,  of guarantor fee expenses to the significant  shareholder as
     compensation  for the guarantees.  During 1995 the significant  shareholder

     1991 through 1994.

     At December  31,  1996,  the Company had a  receivable  of $42,707 due from

(13) Capital Stock

     (a) Preferred Stock

          At incorporation the Board of Directors  authorized  15,000,000 shares
          of preferred  stock.  The terms and conditions of these shares will be
          established at the time of issuance.

     (b) Stock Option Plans

               (i) Compensation Related Options

               When the Company  grants fully paid and vested  stock  options to
               employees as a form of compensation,  the Company  recognizes the
               value of the  options  as  compensation  expense  and  records an
               increase in stockholders'  equity in the year of grant. When such
               options are exercised, stock option equity will be eliminated and
               common stock and paid in capital will increase. Forfeited options
               are  accounted  for by a reduction  in  compensation  expense and
               stockholders' equity.

               Stock Option Plan
               -----------------

               In 1993,  the Company  approved  the Stock Option Plan (the Plan)
               and granted 1,525,839 fully paid and vested options for shares of
               the Company with an option price of $0.72 per share to employees,
               including senior  management,  who elected to receive part or all
               of their  compensation  through January 1993 in the form of stock
               options.  Options granted under the plan shall remain exercisable
               for 10 years after the date of grant.

               As of December 31, 1996, none of these options had been exercised
               and options for 335,394 shares had been terminated as a result of
               employee turnover.  During 1996 and 1995, no options  terminated.
               At  December  31,  1996,  fully  paid  and  vested  options  were
               outstanding  which when  exercised will result in the issuance of
               1,190,445 shares of common stock.

               Other Options Issued
               --------------------

               In 1993,  the Company  granted  fully paid and vested  options to
               acquire  500,000 shares of the Company's  stock to several of the
               employees,  including  senior  management,   relating  to  a  new
               performance-based compensation plan.

               As of December 31, 1996, none of these options had been exercised
               and options for 98,955  shares had  terminated.  At December  31,
               1996, fully paid and vested options were outstanding,  which when
               exercised will result in the issuance of 401,045 shares of common
               stock.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements


               During May 1994,  the  agreements  with employees for both option
               plans described above were amended  retroactive to December 1993.
               For options  outstanding  as of May 1994,  the options  would not
               lapse until after the options  became  exercisable.  The exercise
               period was  amended to the earlier of March 29, 2000 or the later
               of (i) the  date the  Company  goes  public  or (ii) the date six
               months after the underwriter imposed "lock-up," if any, expires.

               (ii) 1993 Stock Option Plan

               During October 1993,  the Company  approved the 1993 Stock Option
               Plan (the 1993 Plan). Under the 1993 Plan, options to purchase an
               aggregate of 4,640,000 shares of common stock, $.01 par value, of
               the Company may be granted to  directors,  officers and full-time
               salaried  employees of the  Company,  as selected by the Board of
               Directors.

               The  purchase  price of each option shall not be less than 85% of
               the fair  market  value of the shares at the time such  option is
               granted. If, however, an optionee owns more than 10% of the total
               combined voting power of all classes of stock of the Company, the
               option price of any option  granted to that optionee shall not be
               less than 110% of such fair market  value at the time such option
               is granted.

               Options granted hereunder may be exercised, subject to applicable
               vesting requirements,  during the ten years after the grant. Each
               option  shall vest at 20% per year and become  fully vested after
               five years, from the date of grant.

               During 1996 and 1995, 0 and  1,717,882  options for shares of the
               Company were granted under this plan to officers and employees of
               the Company, respectively.

               (iii) Other Options

               During October 1995, the Board of Directors authorized and issued
               129,412  options  to  purchase  shares of $0.01 par value  common
               stock at the  exercise  price of $0.85 per share to a vendor  for
               services  rendered.  This issue was not part of any stock  option
               plan  mentioned  above nor was it issued to officers or employees
               of the Company.  These  options shall remain  exercisable  for 10
               years after the date of grant.  As of December 31, 1996,  none of
               these options have been exercised.

(c) Issuance of Common Stock

In  December  1996,  the  Company  issued  1,095,767  shares of common  stock in
exchange  for $10,000  and  services  to be  provided  in  conjunction  with the
Company's  efforts to acquire a publicly  traded  entity in a related  business.
Such shares are subject to a call provision which allows the Company to call the
shares upon  termination of the agreement as long as the Company is not a public
Company or in the process of becoming public.

                                                                     (Continued)

                   Notes to Consolidated Financial Statements


     In 1996,  the  Company  also  issued  11,765  shares of common  stock to an
     employee in exchange for a promissory note in the amount of $10,000.

(14) Employee Benefit Plan

     The Company adopted,  amended and restated the Luminae Inc. 401(k) Plan and
     related Trust. It changed the name of the Plan to Proven Alternatives, Inc.
     401(k) Plan and Trust (Plan) and expanded the Plan to all  employees of the
     Company as of April 1, 1993.  The Company's  contributions  to the Plan are
     discretionary.  The  Company  did not  make any  contributions  to the Plan
     during the years ended December 31, 1996 and 1995.

(15) Commitments and Contingencies

     Under the terms of its employee medical insurance program, the Company pays
     a portion of medical benefits,  administration fees and stop-loss premiums.
     Costs exceeding the $35,000 stop-loss level per covered  individual,  up to
     $1  million,  are  covered  by  a  third  party  insurer.  The  Company  is
     responsible for any costs in excess of $1 million.

     In 1996, the Company  settled a lawsuit  involving  several of the minority
     shareholders  of a  subsidiary.  Under  the  terms of the  settlement,  the
     Company   acquired  the  remaining   minority  shares  and  agreed  to  pay
     approximately   $400,000   to  such   minority   shareholders   in  monthly
     installments over two years.

     In late  1996,  in an  arbitration  filed  by the  owner of  certain  micro
     cogeneration  patents  then  licensed to the  Company,  the Company  became
     subject  to an award in favor of that  owner  in an  amount  in  excess  of
     $1,100,000.  The Company has executed an Agreement To Satisfy Judgement And
     Refrain From Execution On Judgement with the owner under the terms of which
     the  Company  will pay the  judgement  over a period of three years and the
     owner will refrain from any collection  efforts so long as the payments are
     made when due. In connection  with this matter,  the owner has appealed the
     San  Francisco  Superior  Court  confirmed  decision of the  arbitrator  to
     receive legal fees. The Company and its legal  representatives  believe the
     outcome  of this  appeal  will be  favorable  to the  Company.  An  adverse
     decision could require additional payments to the owner of up to $500,000.

     Settlement costs of approximately  $100,000 and $1.4 million related to the
     above  litigation  were included in selling,  general,  and  administrative
     expenses in 1996 and 1995, respectively.

     In May, 1997, the Company was contacted regarding a potential claim related
     to the sale and  installation  of one of its  subsidiary's  early  projects
     which  had been  completed  prior to the  subsidiary's  acquisition  by the
     Company,  and which was abandoned  last year. The Company is in the process
     of evaluating  the claim and estimates  that the potential loss could be in
     the range of $50,000 to $100,000.

Section 259 of the DGCL.

     1.4 Certificate of Incorporation, By-laws and Directors. The Certificate of
Incorporation and By-laws of PAI as in effect immediately prior to the Effective
Time and shall be the Certificate of Incorporation  and By-laws of the Surviving
Corporation  until  thereafter  changed  or amended  as  provided  therein or by
applicable  law.  The  directors  of Sub  at the  Effective  Time  shall  be the
directors of the Surviving  Corporation  until their  successors  have been duly
elected or appointed in accordance  with the  Certificate of  Incorporation  and
By-laws of the Surviving Corporation or by applicable law.

     1.5  Conversion of Securities.  As of the Effective  Time, by virtue of the
Merger and without any action on the part of any stockholder of PAI:

     (a)  All shares of PAI Common Stock that are held in the treasury of PAI or
          by any  wholly  owned  subsidiary  of PAI and any shares of PAI Common
          Stock owned by Dencor or Sub shall be canceled and no capital stock of
          Dencor or other consideration shall be delivered in exchange therefor.

     (b)  Each issued and outstanding share of the capital stock of Sub shall be
          converted  into and become one fully paid and  nonassessable  share of

     (c)  Each share of PAI Common  Stock  issued  and  outstanding  immediately
          prior to the  Effective  Time  (other  than  shares to be  canceled in
          accordance  with Section  1.5(a))  shall be converted  into 1.5 shares
          (the "Exchange Ratio") of validly issued, fully paid and nonassessable
          shares of Dencor  Common  Stock.  All such shares of PAI Common Stock,
          when  so  converted,   shall  no  longer  be  outstanding   and  shall
          automatically be canceled and retired and each holder of a Certificate
          (as defined in Section  1.6(a))  representing  any such  shares  shall
          cease to have any rights  with  respect  thereto,  except the right to

          Agent hereunder (the Exchange Agent). As soon as practicable after the
          Effective  Time,  Dencor shall deposit with the Exchange Agent for the
          benefit of the holders of certificates  which immediately prior to the
          Effective   Time   represented   shares  of  PAI  Common   Stock  (the
          Certificates)  certificates  representing  the shares of Dencor Common
          Stock (such shares of Dencor Common Stock being  hereinafter  referred
          to as the  Exchange  Fund)  issuable  pursuant  to Section  1.5 (c) in
          exchange  for  outstanding  shares  of  PAI  Common  Stock.

     (b)  Exchange Procedures.  As soon as practicable after the Effective Time,
          the  Exchange  Agent  shall  mail  to  each  holder  of  record  of  a
          Certificate  whose  shares  (and  associated  rights)  were  converted
          pursuant to Section 1.5 into shares of Dencor Common Stock a letter of
          transmittal (which shall specify that delivery shall be effected,  and
          risk of loss and  title to the  Certificates  shall  pass,  only  upon
          actual and proper  delivery of the  Certificates to the Exchange Agent
          and shall contain  instructions  for use in effecting the surrender of
          the Certificates in exchange for certificates  representing  shares of
          Dencor  Common  Stock and shall be in such form and contain such other
          provisions as Dencor and PAI may reasonably  specify).  Upon surrender
          of a Certificate for cancellation to the Exchange Agent, together with
          such  letter  of  transmittal,  duly  executed,  the  holder  of  such
          Certificate  shall be  entitled  to  receive  in  exchange  therefor a
          certificate  representing  the number of whole shares of Dencor Common
          Stock  which such  holder has the right to  receive  pursuant  to this
          Article 1, and the  Certificate  so  surrendered  shall  forthwith  be
          canceled.  Until surrendered as contemplated by this Section 1.6, each
          Certificate  shall,  at and after  the  Effective  Time,  be deemed to
          represent   only  the  right  to  receive,   upon  surrender  of  such
          Certificate,  the certificate  representing the appropriate  number of
          shares of Dencor Common Stock.





     1.7 No Fractional Shares. No certificates or scrip representing  fractional
shares of Dencor Common Stock shall be issued upon the surrender for exchange of
Certificates  pursuant  to this  Article  1,  and no  Decor  dividend  or  other
distribution  or stock  split or  combination  shall  relate  to any  fractional
security,  and such fractional  interests shall not entitle the owner thereof to
vote or to any rights of a security  holder of Dencor.  Each  stockholder of PAI
who is  entitled  to  receive  0.5 or more of a share  of  Dencor  Common  Stock
pursuant to Section 1.5(c)shall receive the total number of whole share to which
that holder is entitled and a single whole share of Dencor Common Stock in place
of that  fractional  share.  Each  stockholder of PAI who but for this provision
would be entitled  to receive  less than 0.5 of a share of Dencor  Common  Stock
pursuant to Section  1.5(c) shall  receive only the total number of whole shares
to which the  stockholder is entitled,  and any such  fractional  share shall be
eliminated for all purposes without compensation therefor.

     1.8 Closing. The closing of the transactions contemplated by this Agreement
(the  Closing)  shall take place at the offices of PAI,  1740 Army  Street,  San
Francisco, California at 10:00 a.m. local time, on the second business day after

hereof  shall have been  fulfilled  or waived or at such other time and place as
PAI and Dencor shall agree.

under applicable law.

outofpocket  limits  applicable under the medical plan of PAI provided as of the
Effective  Time with respect to the balance of such plan year to the same extent
as if such  amounts  had been paid  under  such  medical  plan of PAI;  provided
however  that,  notwithstanding  the  foregoing,  for a  period  of  five  years
following the Effective  Time  employees of the Dencor  Division  shall have the
right to continue their medical coverage under Dencor's medical health insurance

designee of Moe reasonably acceptable to the Dencor Board of Directors, to serve
as a  Director  of  Dencor,  which  Director  shall  be  entitled  to  the  same
compensation,  reimbursement  of expenses and perquisites as are provided to the
other directors of Dencor.

     8.13  Promissory  Notes.  Attached to this  Agreement as Schedule 8.13 is a
list of all  outstanding  loans to Dencor from  shareholders of Dencor and other
lenders,  which loans are  evidenced by  promissory  notes (the  "Notes") in the
aggregate  principal  amount of $108,250,  which bear  interest at rates ranging
from 10 percent per annum to 18.25 percent per annum.  The  aggregate  principal
amount and accrued  interest  owed pursuant to the Notes as of June 30, 1997 was
$177,570.90.  With the exception of the Note from Dencor to PAI, which is due on
or before July 31,  1997,  the Notes are due upon  demand.  Dencor and PAI agree
that after the Effective Time, PAI will cause sufficient funds to be distributed
or loaned to Dencor with which to satisfy the  repayment  of the Notes that have
not be repaid as of the Effective Time.

                                    Annex II


ss. 262.  Appraisal rights.

     (a) Any  stockholder  of a  corporation  of this State who holds  shares of
stock on the date of the making of a demand  pursuant to subsection  (d) of this
section with respect to such shares,  who continuously holds such shares through
the effective date of the merger or  consolidation,  who has otherwise  complied
with  subsection  (d) of this section and who has neither  voted in favor of the
merger or consolidation  nor consented thereto in writing pursuant to ss. 228 of
this title  shall be entitled  to an  appraisal  by the Court of Chancery of the
fair  value  of the  stockholder's  shares  of  stock  under  the  circumstances
described in subsections  (b) and (c) of this section.  As used in this section,
the word "stockholder"  means a holder of record of stock in a stock corporation
and also a member of record of a nonstock  corporation;  the words  "stock"  and
"share"  mean and  include  what is  ordinarily  meant by those  words  and also
membership or membership interest of a member of a nonstock corporation; and the
words  "depository  receipt"  mean a  receipt  or other  instrument  issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b)  Appraisal  rights  shall be  available  for the shares of any class or
series of stock of a constituent  corporation in a merger or consolidation to be
effected  pursuant to ss.251 (other than a merger effected pursuant to ss.251(g)
of this title), ss.252, ss.254, ss.257, ss.258, ss.263, or ss.264 of this title:

          (1)  Provided,  however,  that no appraisal  rights under this section
     shall be  available  for the shares of any class or series of stock,  which
     stock, or depository  receipts in respect thereof, at the record date fixed
     to determine the stockholders  entitled to receive notice of and to vote at
     the  meeting  of  stockholders  to act  upon the  agreement  of  merger  or
     consolidation,  were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of  record  by more  than  2,000  holders;  and  further  provided  that no
     appraisal  rights  shall  be  available  for any  shares  of  stock  of the
     constituent  corporation  surviving  a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving  corporation
     as provided in subsection (f) of ss.251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent  corporation if the holders  thereof are required
     by the terms of an agreement of merger or consolidation  pursuant to ss.ss.
     251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock
     anything except:

               a. Shares of stock of the corporation surviving or resulting from
          such  merger or  consolidation,  or  depository  receipts  in  respect
          thereof;

               b.  Shares  of  stock of any  other  corporation,  or  depository
          receipts  in  respect  thereof,  which  shares of stock or  depository
          receipts at the effective date of the merger or consolidation  will be
          either  listed on a national  securities  exchange or  designated as a
          national market system security on an interdealer  quotation system by
          the National Association of Securities Dealers, Inc. or held of record
          by more than 2,000 holders;

                                       1

<PAGE>


               c. Cash in lieu of  fractional  shares or  fractional  depository
          receipts  described in the foregoing  subparagraphs  a. and b. of this
          paragraph; or

               d. Any  combination of the shares of stock,  depository  receipts
          and  cash  in lieu  of  fractional  shares  or  fractional  depository
          receipts  described in the  foregoing  subparagraphs  a., b. and c. of
          this paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger  effected  under ss.253 of this title is not owned by the
     parent corporation immediately prior to the merger,  appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its  certificate of  incorporation  that
appraisal  rights  under this section  shall be available  for the shares of any
class or series of its stock as a result of an amendment to its  certificate  of
incorporation,  any  merger  or  consolidation  in which  the  corporation  is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation.  If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or  consolidation  for which appraisal rights
     are  provided  under this  section is to be  submitted  for  approval  at a
     meeting of stockholders,  the  corporation,  not less than 20 days prior to
     the  meeting,  shall  notify each of its  stockholders  who was such on the
     record date for such  meeting  with  respect to shares for which  appraisal
     rights  are  available  pursuant  to  subsection  (b)  or (c)  hereof  that
     appraisal  rights  are  available  for  any or all  of  the  shares  of the
     constituent  corporations,  and shall include in such notice a copy of this
     section.  Each  stockholder  electing to demand the appraisal of his shares
     shall  deliver  to the  corporation,  before  the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably  informs the  corporation of the
     identity of the  stockholder  and that the  stockholder  intends thereby to
     demand the  appraisal of his shares.  A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take  such  action  must  do so by a  separate  written  demand  as  herein
     provided.  Within  10 days  after  the  effective  date of such  merger  or
     consolidation,  the  surviving or resulting  corporation  shall notify each
     stockholder  of each  constituent  corporation  who has complied  with this
     subsection  and has not  voted in favor of or  consented  to the  merger or
     consolidation  of the date that the  merger  or  consolidation  has  become
     effective; or

          (2) If the merger or consolidation was approved pursuant to ss. 228 or
     ss.253 of this  title,  each  constituent  corporation  either  before  the
     effective  date  of  the  merger  or   consolidation  or  within  ten  days
     thereafter,  shall  notify  each of the  holders  of any class or series of
     stock of such constituent  corporation who are entitled to appraisal rights
     of the approval of the merger or  consolidation  and that appraisal  rights
     are  available  for any or all  shares of such  class or series of stock of
     such  constituent  corporation,  and shall include in such notice a copy of
     this  section;  provided  that,  if the  notice  is given on or a after the
     effective date of the merger or  consolidation,  such notice shall be given
     by the surviving or resulting  corporation to all such holders of any class
     or  series  of stock of a  constituent  corporation  that are  entitled  to
     appraisal rights.  Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     

                                       2

<PAGE>


of the effective date of the merger or consolidation.  Any stockholder  entitled
to  appraisal  rights  may,  within 20 days  after the date of  mailing  of such
notice,  demand in writing  from the  surviving  or  resulting  corporation  the
appraisal  of  such  holder's  shares.  Such  demand  will be  sufficient  if it
reasonably  informs the  corporation of the identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of such holder's shares.
If such notice did not notify  stockholders  of the effective date of the merger
or  consolidation,  either (i) each such  constituent  corporation  shall send a
second notice before the effective date of the merger or consolidation notifying
each of the  holders  of any  class  or  series  of  stock  of such  constituent
corporation  that are entitled to appraisal  rights of the effective date of the
merger or  consolidation  or (ii) the surviving or resulting  corporation  shall
send such a second  notice to all such  holders  on or within 10 days after such
effective date; provided,  however, that if such second notice is sent more than
20 days following the sending of the first notice,  such second notice need only
be sent to each  stockholder  who is  entitled to  appraisal  rights and who has
demanded  appraisal of such holder's shares in accordance with this  subsection.
An affidavit of the secretary of assistant secretary or of the transfer agent of
the corporation that is required to give either notice that such notice has been
given  shall,  in the  absence of fraud,  be prima  facie  evidence of the facts
stated therein. For purposes of determining the stockholders entitled to receive
either notice,  each constituent  corporation may fix, in advance, a record date
that  shall be not more  than 10 days  prior to the date the  notice  is  given,
provided,  that if the  notice  is given on or after the  effective  date of the
merger or  consolidation,  the record date shall be such effective.  date. If no
record date is fixed and the notice is given prior to the  effective  date,  the
record date shall be the close of business on the day next  preceding the day on
which the notice is given.

     (e)  Within  120  days   after  the   effective   date  of  the  merger  or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with  subsections  (a) and (d) hereof and who is otherwise  entitled to
appraisal  rights,  may file a petition  in the Court of  Chancery  demanding  a
determination   of  the   value  of  the   stock   of  all  such   stockholders.
Notwithstanding  the  foregoing,  at any time within 60 days after the effective
date of the merger or  consolidation,  any  stockholder  shall have the right to
withdraw  his demand for  appraisal  and to accept  the terms  offered  upon the
merger or consolidation.  Within 120 days after the effective date of the merger
or  consolidation,  any  stockholder  who has complied with the  requirements of
subsections  (a) and (d)  hereof,  upon  written  request,  shall be entitled to
receive  from  the  corporation  surviving  the  merger  or  resulting  from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or  consolidation  and with respect to which  demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written  statement shall be mailed to the stockholder  within 10 days after
his  written  request  for such a statement  is  received  by the  surviving  or
resulting  corporation  or within 10 days  after  expiration  of the  period for
delivery of demands for  appraisal  under  subsection  (d) hereof,  whichever is
later.

     (f) Upon the filing of any such  petition  by a  stockholder,  service of a
copy thereof  shall be made upon the surviving or resulting  corporation,  which
shall  within 20 days after such  service  file in the office of the Register in
Chancery in which the petition was filed a duly  verified  list  containing  the
names and  addresses of all  stockholders  who have  demanded  payment for their
shares and with whom  agreements  as to the value of their  shares have not been
reached by the  surviving or  resulting  corporation.  If the petition  shall be
filed  by  the  surviving  or  resulting  corporation,  the  petition  shall  be
accompanied  by such a duly  verified  list.  The  Register in  Chancery,  if so
ordered by the  Court,  shall  give  notice of the time and place  fixed for the
hearing of such petition  by registered of certified  mail  to  the surviving or


                                       3


<PAGE>

resulting corporation and to the stockholders shown on the list at the addresses
therein  stated.  Such notice shall also be given by 1 or more  publications  at
least  1  week  before  the  day of  the  hearing,  in a  newspaper  of  general
circulation published by the City of Wilmington, Delaware of such publication as
the Court deems  advisable.  The forms of the notices by mail and by publication
shall be  approved  by the Court,  and the costs  thereof  shall be borne by the
surviving or resulting corporation.

     (g) At the  hearing  on  such  petition,  the  Court  shall  determine  the
stockholders who have complied with this section and who have become entitled to
appraisal  rights.  The Court may require the  stockholders who have demanded an
appraisal for their shares and who hold stock  represented  by  certificates  to
submit  their  certificates  of stock to the  Register in Chancery  for notation
thereon of the pendency of the  appraisal  proceedings;  and if any  stockholder
fails to comply with such  direction,  the Court may dismiss the proceedings as
to such stockholder.

     (h) After determining the stockholders entitled to an appraisal,  the Court
shall appraise the shares, determining their fair value exclusive of any element
of value  arising  from the  accomplishment  or  expectation  of the  merger  or
consolidation,  together  with a fair rate of interest,  if any, to be paid upon
the amount  determined  to be the fair value.  In  determining  the fair rate of
interest,  the Court may consider all relevant  factors,  including  the rate of
interest which the surviving or resulting  corporation  would have had to pay to
borrow money  during the pendency of the  proceeding.  Upon  application  by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceedings, the Court may, in its discretion, permit discovery
or other pretrial  proceedings and may proceed to trail upon the appraisal prior
to the final  determination  of the  stockholder  entitled to an appraisal.  Any
stockholder  whose name appears on the list filed by the  surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates  of stock to the  Register in Chancery,  if such is  required,  may
participate fully in all proceedings  until it is finally  determined that he is
not entitled to appraisal rights under this section.

     (i) The Court  shall  direct the  payment of the fair value of the  shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto.  Interest may be simple or compound, as the Court
may  direct.  Payment  shall be made to each  such  stockholder,  in the case of
holders of  uncertificated  stock  forthwith,  and the case of holders of shares
represented  by  certificates  upon  the  surrender  to the  corporation  of the
certificates  representing  such stock.  The  Court's  decree may be enforced as
other decrees in the Court of Chancery may be enforced,  whether such  surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the  proceeding  may be  determined by the Court and taxed
upon the  parties  as the  Court  deems  equitable  in the  circumstances.  Upon
application  of a  stockholder,  the Court  may  order  all or a portion  of the
expenses   incurred  by  any   stockholder  in  connection  with  the  appraisal
proceeding,  including,  without limitation,  reasonable attorney's fees and the
fees and  expenses of experts,  to be charged pro rata  against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective  date of the merger or  consolidation,  no
stockholder who has demanded his appraisal  rights as provided in subsection (d)
of this  section  shall be  entitled  to vote such  stock for any  purpose or to
receive  payment  of  dividends  or other  distributions  on the  stock  (except
dividends or other  distributions  payable to  stockholders  of record at a date
which is prior to the effective date of the merger or consolidation);  provided,
however,  that if no petition  for an  appraisal  shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver


                                       4

<PAGE>


to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation,  either within 60
days after the  effective  date of the merger or  consolidation  as  provided in
subsection  (e) of this section or thereafter  with the written  approval of the
corporation,  then the right of such  stockholder  to an appraisal  shall cease.
Notwithstanding the foregoing,  no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder  without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (l) The  shares of the  surviving  or  resulting  corporation  to which the
shares  of such  objecting  stockholders  would  have  been  converted  had they
assented to the merger or consolidation  shall have the status of authorized and
Unicode shares of the surviving or resulting corporation.
