      ATLANTIC CENTRAL ENTERPRISES LIMITED (THE "COMPANY" OR "ACE") HAS
EXPERIENCED SIGNIFICANT NET LOSSES SINCE INCEPTION, FOR THE FISCAL YEAR ENDED
FEBRUARY 28, 1997 INCURRED A LOSS FROM OPERATIONS OF APPROXIMATELY $10,316,000
AND UTILIZED APPROXIMATELY $4,173,000 IN CASH FOR OPERATING ACTIVITIES, AND AT
FEBRUARY 28, 1997 HAD A WORKING CAPITAL DEFICIT OF APPROXIMATELY $874,000 AND
A STOCKHOLDERS' EQUITY OF APPROXIMATELY $306,000.  THE COMPANY HAS SERIOUS
LIQUIDITY PROBLEMS PRIMARILY DUE TO UNSUCCESSFUL ATTEMPTS THROUGH ITS
SUBSIDIARY, VISTA TECHNOLOGIES INC. ("VISTA"), TO RAISE ADDITIONAL CAPITAL AND
SIGNIFICANT COSTS ASSOCIATED WITH FAILED ATTEMPTS TO PENETRATE NORTH AMERICAN
VISION CORRECTION MARKETS.  AS A RESULT OF THE ABOVE FACTORS, THE REPORT OF
MOORE STEPHENS, P.C. ON THE FINANCIAL STATEMENTS OF THE COMPANY FOR THE FISCAL
YEAR ENDED FEBRUARY 28, 1997 CONTAINS A PARAGRAPH EXPRESSING SUBSTANTIAL DOUBT
CONCERNING THE ABILITY OF THE COMPANY TO CONTINUE AS A GOING CONCERN.  THE
CONSOLIDATED FINANCIAL STATEMENTS DO NOT INCLUDE ANY ADJUSTMENTS THAT MIGHT BE
NECESSARY IF THE COMPANY IS UNABLE TO CONTINUE AS A GOING CONCERN.  FOR A
DISCUSSION OF MANAGEMENT'S PLANS AND OTHER RELATED FACTORS, SEE "MANAGEMENT'S
DISCUSSION AND ANALYSIS OR PLAN OF OPERATION" IN ITEM 6 BELOW AND THE
CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO LATER IN THIS REPORT.

      UNLESS OTHERWISE INDICATED, ALL SHARE AND PER SHARE DATA IN THIS REPORT
HAVE BEEN ADJUSTED RETROACTIVELY TO REFLECT A 1-FOR-10 EXCHANGE RATIO AS TO
PHARMA PATCH PLC SHARES PURSUANT TO THE REORGANIZATION OF PHARMA PATCH AND
ATLANTIC CENTRAL ENTERPRISES LIMITED EFFECTIVE AS OF JANUARY 20, 1997.


ITEM 1.     DESCRIPTION OF BUSINESS

INTRODUCTION

      Atlantic Central Enterprises, Ltd. (the "Company" or "ACE") was
incorporated under the laws of Bermuda on February 2, 1996 under the name
Bamburgh Limited.  Thereafter, on April 2, 1996, the name was changed to
"Atlantic Central Enterprises Limited".

      On January 20, 1997, ACE completed a reorganization with Pharma Patch
Public Limited Company, an Irish company ("Pharma Patch").  The reorganization
involved Pharma Patch transferring to ACE all of its assets and having ACE
assume all of Pharma Patch's liabilities, in exchange for all the then
outstanding common stock of ACE.  Immediately after the transfer Pharma Patch
commenced a voluntary liquidation and distributed all ACE's shares to its
shareholders.  As a result of the reorganization, Pharma Patch shareholders
received one common share of ACE for every 10 shares of Pharma Patch owned. 
This reorganization qualifies as a tax-free reorganization under Section
368(1)(1)(F) of the U.S. Internal Revenue Code of 1986, as amended. 

      As a result of the restructuring, ACE is the successor in interest of
Pharma Patch.  Accordingly, "ACE" or the "Company" will be used
interchangeably to refer to ACE and Pharma Patch when describing operational
history unless otherwise specifically indicated.

      The principal office of the Company is located at Cedar House, 41 Cedar
Avenue, Hamilton, Bermuda HM 12, telephone number (441) 295-2244.

REORGANIZATION

      On January 20, 1997, the shareholders of Pharma Patch approved the
following plan of reorganization with Atlantic Central Enterprises ("ACE"):

      ACE was initially capitalized in August 1996 by issuing 1,200,000 shares
of common stock to Pharma Patch for $12,000 in cash.

      Subsequent to the reorganization, ACE issued an additional 450,000
shares of its common stock in exchange for the stock held by the stockholders
of Pharma Patch and dissolved the corporate charter of Pharma Patch.


                                    -3-
<PAGE>
      These transactions resulted in the elimination of the 16,541,570
ordinary shares of Pharma Patch and created 1,654,157 shares of common stock
(one share of ACE common stock for every 10 Ordinary shares of Pharma Patch)
in ACE with a par value of $16,542.  As a result of the difference between
Pharma Patch's ordinary shares issued at par value ($2,343,914) and ACE's
common stock issued at par value ($16,542) the premium in excess of par value
increased, in 1997, by $2,327,372 (Pharma Patch's par value per ordinary 
share was Irish Pounds .01 and ACE's par value per common share is US$ .01).
All per share amounts in this report have been restated to reflect this
reorganization.

      Pharma Patch was incorporated under the laws of the Republic of Ireland
in January 1992.  Prior to July 1993, Pharma Patch had no significant assets
or operations.  Prior to fiscal 1997 Pharma Patch was mainly involved in the
research and development of transdermal drug delivery systems and skin
permeation technology.  Pharma Patch developed and patented proprietary
technology and secured licensing and product feasibility agreements through
research in this area.         
      
      On November 15, 1995, Pharma Patch sold substantially all of its
operating assets to Technical Chemicals and Products, Inc. ("TCPI") for a gain
of approximately $16.4 million. These assets included 11 U.S. patents relating
to transdermal drug delivery and skin permeation technology, license rights to
skin penetration enhancers and electronically assisted drug delivery,
proprietary information and trade secrets related thereto, certain licensing
and product feasibility agreements entered into by Pharma Patch's and all of
Pharma Patch's fixed assets. TCPI also assumed the sublease of the research
facility occupied by Pharma Patch.

      In consideration for the purchased assets, TCPI issued an aggregate of
786,214 shares of its common stock with a fair value of $11,919,000 and
satisfied the $5,000,000 promissory note previously issued by Pharma Patch to
Flora, Inc.  As a result of this transaction, Pharma Patch owned 9.9% of
TCPI's outstanding common shares and ceased performing research and
development work and other operations in the areas of skin penetration
enhancers and drug delivery systems. 
      
      On January 16, 1996, Pharma Patch entered into a supplemental agreement
with TCPI, which amended certain provisions of the November 1995, asset
purchase agreement. TCPI had filed a Registration Statement on Form S-1 with
the Securities and Exchange Commission with respect to the sale of 1,800,000
TCPI common shares (the "Offering"). Pursuant to the terms of the supplemental
agreement, Pharma Patch executed a lock-up letter with the representative of
the TCPI Underwriters providing that it would not sell or otherwise dispose of
any of its shares of common stock for a period to expire 180 days following
the closing date of the Offering without their prior consent. As consideration
for the execution of the lock-up agreement, TCPI (i) terminated an existing
lock-up agreement covering TCPI common stock owned by Pharma Patch, executed
in connection with the asset purchase agreement; (ii) effective as of closing
date of the Offering, terminated the voting trust agreements, shareholders'
agreement and irrevocable proxy, executed in connection with the asset
purchase agreement which, among other things, limited Pharma Patch's ability
to vote or dispose of its shares of common stock; (iii) allowed Pharma Patch
to offer for sale 100,000 shares of this common stock in the Offering (plus up
to an additional 110,000 shares if the Underwriters over-allotment option were
exercised); (iv) effective as of the closing date of the Offering, issued to
Pharma Patch a two-year warrant to purchase 100,000 shares of common stock at
an exercise price equal to the per share Offering price; and (v) file a
Registration Statement on Form S-3 to register all of the remaining shares of
common stock owned by Pharma Patch after the Offering. 

      On March 21, 1996, ACE completed the acquisition of 61.3% of the voting
interest of Vista Technologies, Inc. ("Vista").  Vista provides
photo-refractive keratectomy (PRK) and other laser vision correction ("LVC")
facilities and services to the health care industry. 

                                    -4-
<PAGE>
      ACE acquired its position in Vista by executing a stock purchase
agreement for 200,000 newly issued shares of Vista common stock for a cash
price of $500,000.  ACE and Vista executed an additional agreement under which
Vista provided 2,060,000 newly issued shares of its common stock to ACE plus
500,000 Vista Class C common stock purchase warrants.  In exchange, Vista
received a $750,000 interest-free note due six months after the transaction
date and 200,000 restricted shares of TCPI common stock previously held by ACE
with a fair value on the date of the transaction of $3,550,000 (original cost
basis to ACE of $3,032,000).  Vista paid the $750,000 note in full during the
first quarter of fiscal 1997.  ACE also received an option to acquire 250,000
Vista shares at $2.50 per share.  In a separate transaction, ACE agreed to
provide 4,500,000 newly issued Ordinary Shares of Pharma Patch (450,000 common
shares of ACE) in exchange for a total of 900,000 shares of Vista's
outstanding common stock owned by three shareholders.  A summary of the
consideration for both components of the Vista transaction include the
following:

      Pharma Patch common stock (4,500,000 shares)           2,250,000

                                                           ===========
</TABLE>

      The cost in excess of net assets acquired of approximately $4.5 million
was calculated utilizing the original carrying value of the TCPI investment
($15.16 per share).  ACE was amortizing such cost in excess of net assets
acquired over a 15-year period.  At February 28, 1997, the Company's
management determined that the goodwill was impaired.  As a result, the
Company wrote off goodwill of approximately $4,300,000 after it determined
that the unamortized balance of goodwill could not be recovered through
projected future discounted cash flows over its remaining life [See Note 2 of
the Notes to Consolidated Financial Statements].

      During the year ACE exercised its options to purchase an additional
250,000 shares of Vista for cash consideration of $625,000.   ACE also
purchased additional 13,800 shares on the open market for cash consideration
of $37,663.

      Since March 21, 1996, ACE's interest in Vista has been diluted by the
issuance of additional Vista stock.  At February 28, 1997, ACE owned 54.14% of
the issued and outstanding shares of Vista. 

      The accompanying consolidated financial statements have been prepared in
conformity with generally accepted accounting principles, which contemplates
continuation of the Company as a going concern and realization of assets and
settlement of liabilities and commitments in the normal course of business. 
The Company has experienced significant net losses, a loss from continuing
operations of approximately $10,316,000, has a working capital deficit of
approximately $874,000 and utilized approximately $4,173,000 in cash for
operating activities for the year ended February 28,1997.  In addition, Vista
has serious liquidity problems primarily due to unsuccessful attempts to raise
money, both at the parent level and the subsidiary level and significant costs
associated with the Vista's failed attempts to penetrate the North American
vision correction market resulting in losses from operations.  The Company and
its subsidiaries are developing business plans which when implemented would
develop opportunities in the laser vision correction and automotive
maintenance markets in North America and/or Europe.  Vista's management is
developing a business plan which takes advantage of new trends in the laser

                                    -5-
<PAGE>
vision correction business in both North America and Europe.  Vista plans to
concentrate on its four successful centers in Italy and Sweden in the 1997-
1998 fiscal year and focus on the reduction of expenses at the head office
level.  The Company also plans to sell a portion of its marketable securities,
obtain additional debt financing and focus on revenue growth of its existing
operations.

      The financial statements do not include any adjustments that might be
necessary if the Company is unable to continue as a going concern.  The
continuation of the Company as a going concern is dependent upon the success
of these plans.  There can be no assurance of the success of these plans.

      As of February 28, 1997 ACE has an accumulated deficit of $18,692,005,
total assets of $8,118,894 and total shareholders' equity of $306,293.

      ACE's majority owned subsidiary, Vista, has an accumulated deficit of
$22,142,284, total assets of $4,330,537, total shareholders deficiency of
$2,094,820 and received a Going Concern qualification report from its auditors
for the twelve months ended March 31, 1997 (see Vista's report on Form 10KSB
for its fiscal year ended March 31, 1997 for additional information).  ACE,
including Vista, has not yet achieved profitable operations and there is no
assurance that profitable operations, if achieved, could be sustained on a
continuing basis. Further, Vista's future operations are dependent on the
success of the commercialization efforts and market acceptability of the Vista
business plan and other potential business ventures of ACE, together with the
value derived from the TCPI investment securities. 

VISTA TECHNOLOGIES INC.

      Vista Technologies Inc., through its operating subsidiaries in the
United States and Europe, provides access to advanced excimer laser vision
correction ("LVC") equipment and related support services (collectively "LVC
Services") for use by licensed ophthalmologists in the treatment of refractive
vision disorders.  Vista currently has five lasers in use in Europe and one in
the United States.

      Physicians use computer-controlled excimer lasers at Vista's centers to
treat refractive vision disorders such as nearsightedness (myopia)and
astigmatism and to eliminate or reduce the need for corrective lenses. Vista
provides individual physicians and group ophthalmic practices with shared
access to laser equipment, thus eliminating capital costs, investment risk and
maintenance of such equipment by the health care professional.  LVC Services
provided by Vista also include various support services, such as physician and
staff training, technical support services, equipment maintenance, billing and
accounting and other administrative services.  The Company realizes revenues
for the use of its LVC equipment and services by charging fees at the time
each LVC corrective procedure is performed with use of Vista's equipment.

      Photorefractive keratectomy ("PRK") involves the use of an excimer laser
to reshape the cornea, thereby adjusting its refractive power.  The excimer
laser can also be used to treat a number of pathological superficial corneal
disorders in a procedure called phototherapeutic keratectomy ("PTK"). Two
manufacturers, Summit Technology, Inc. ("Summit") and VISX, Incorporated
("VISX"), received U.S. Food and Drug Administration ("FDA") approval in late
1995 and early 1996, respectively, for use of their excimer lasers to perform
PRK procedures to correct low to moderate nearsightedness and earlier received
FDA approval for use of excimer laser for PTK procedures.  In addition to such
procedures, excimer lasers can also be used to perform a procedure known as
laser in situ keratomileusis ("LASIK"), which may be more predictable in
treating high myopia, but to date has not been specifically approved in the
United States by the FDA.
      
      Vista's European operating subsidiaries have owned and operated excimer
laser facilities in Italy and Sweden since 1992 and 1994, respectively.  In
May 1996, Vista Laser Centers of the Southwest, Inc.("Vista-Southwest")
commenced operations at a excimer laser facility in Scottsdale, Arizona.

                                    -6-
<PAGE>
Vista-Southwest in October 1997 subsequently authorized a change in its
corporate name to Icon Vision Laser Centers SW, Inc.  The Company held an
investment interest in Vista-Southwest prior to October 1996, at which time
Vista's ownership of Vista-Southwest increased to 94%.

      In anticipation of U.S. Food and Drug Administration ("FDA") approval of
excimer lasers to perform PRK procedures, Vista developed a strategic
expansion plan in June 1995 to organize and sponsor additional companies to
provide LVC Services in the United States and Canada through regional joint
venture alliances with certain prominent ophthalmologists (the "Regional Joint
Ventures").  During the quarter ended December 31, 1996, Vista's negotiations
to acquire interests in additional LVC operations, based primarily in Canada,
were abandoned and Vista sold all of its interest in a Regional Joint Venture
formed during 1996 to service the Northern California market.  Unsuccessful
efforts by Vista's former management to obtain additional private placement
equity financing necessary to finance Vista's Regional Joint Venture expansion
plans and to support general and administrative expenses in North America were
terminated during March 1997.

      Vista's management intends to reactivate a strategic expansion plan if a
debt compromise plan with Vista's creditors is proposed and accepted and if
significant additional capital is obtained; there can be no assurance that
Vista will be successful in accomplishing either of these objectives.  Pending
further developments, Vista has been advised that its controlling stockholder,
ACE , plans to pursue a strategic plan of negotiating to acquire or develop
interests in the laser vision correction facilities and services in North
America.  Vista has been advised that if ACE can successfully implement a
strategy of North American expansion in the field of laser vision correction,
it anticipates that Vista will be provided the right to acquire such
operations at an amount equal to ACE's cost if Vista completes a debt
compromise plan with its creditors and if significant additional capital is
obtained by Vista. 

      At March 31, 1997, Vista had a negative working capital of $3,118,789
and a stockholders' deficit of $2,094,820.  Vista has been dependent during
most of its fiscal year ended March 31, 1997 upon stock sales of approximately
$1,500,000 and in subsequent periods upon advances from its controlling
stockholder, ACE, for funds necessary to sustain operations in North America
and Vista's reporting obligations as a publicly-held corporation.  Net
advances due to ACE of $723,000 are classified as unpaid short-term
obligations as of March 31, 1997, and have subsequently increased to
approximately $1,100,000 as of September 30, 1997.  There can be no assurance
that ACE will continue to provide advances to Vista or that Vista will be
successful in obtaining capital from other sources.


RECENT DEVELOPMENTS

      FIRST AMERICAN AMO

      In May 1997 ACE entered into an agreement to form a new corporation
called First American AMO ("AMO").   ACE agreed to fund AMO up to $450,000
prior to any separate outside funding of AMO.  ACE has also agreed to seek out
additional outside funding for AMO for continued growth. ACE owned 83% of the
issued and outstanding common stock of AMO upon signing this agreement.  As of
January 30, 1998 ACE has advanced AMO $275,359 of its $450,000 obligation.

      AMO has its headquarters in Palm Harbor, Florida.  It is an automotive
maintenance organization that improves the efficiencies of fixing a car.  AMO
is assigned a collision claim from an insurance company and comes up with the
lowest cost estimate by  having its own adjusters negotiate with a network of
established body shops.  Motorists receive a lifetime warranty on the repairs

      Insurance companies and consumers benefit from the fast turn-around time
of five days, as opposed to the industry average of seven to ten  and the
reduction in claims administration costs by AMO having its own adjusters.  AMO
has achieved this reduced turn-around time by placing a personal computer with
each insurer so it is directly on-line with AMO.  Body shops are also on-line
with the company with the ability to transmit digital photos of the required
repairs for immediate, and flexible assessment by AMO's adjusters.
     
      AMO is currently servicing five insurance companies and is negotiating
with an additional eleven to come on-line in 1998.  The Company began its
collision management operations in September 1997.  AMO is planning to develop
its fleet management service in March of 1998 with customers and contracts
already targeted.

      AMO's President is Mr. Jeffrey Dickson.  He worked for Miami-based
American Bankers Insurance from 1970 to 1983, becoming executive vice
president, and then six years with Capital Holdings Inc. in Louisville KY.  He
was also president of Insurance America Co., a personal lines insurer that was
a joint venture of Bank of America and Capital Holdings.  Eric Seidel, who is
VP Marketing for AMO and Vic Grechniw, VP Operations for AMO both come from
extensive backgrounds in fleet management.

      ICON VISION CENTERS INC.

      In August 1997, ACE organized ICON Vision Centers Inc., as a wholly
owned subsidiary, in Ontario, Canada to negotiate the acquisition of interests
in additional laser vision correction facilities.  ICON Vision Centers, Inc.
is currently developing a business plan which, if implemented, would cause
ICON Vision Centers to develop opportunities in North America and/or Europe
through acquisitions or start-up development.

      INTERNET VENTURE

      ACE entered into an agreement with a third party in August 1997, to fund
the development of various internet business ventures up to a total of
approximately $57,000.  Currently ACE is re-evaluating the proposed ventures
and the direction of this investment.


VISTA TECHNOLOGIES INC. -- BACKGROUND INFORMATION

      VISION DISORDERS AND ALTERNATE FORMS OF CORRECTIVE TREATMENT

      The human eye is approximately 25 millimeters in diameter and functions
much like a camera, with a lens in front and a light sensitive screen, the
retina, in the rear.  Images enter the human eye through the cornea, a
transparent domed window at the front of the eye.  In a properly functioning
eye, the cornea bends (refracts) incoming images, causing the images to focus
on the retina.  The inability of the cornea to properly refract incoming
images results in blurred vision and is called a refractive disorder. 

     Myopia (nearsightedness), hyperopia (farsightedness) and astigmatism are
three of the most common refractive disorders resulting from an inability of
the optic system to properly focus images on the retina.  The amount of
refraction is dependent on the shape, specifically the curvature, of the
cornea.  In a nearsighted (myopic) eye, images are focused in front of the
retina; in a farsighted (hyperopic) eye, images are focused behind the retina;
and in an astigmatic eye, images are not focused at any one single point.

      Conventional methods of correcting refractive disorders are by
prescription of eyeglasses and contact lenses.  Over the last 15 years,
refractive vision disorders have also been treated by several surgical
techniques.  These include radial keratotomy ("RK"), in which small incisions
approximately 400 to 450 microns deep in a radial configuration are made
around the periphery of the cornea to cause a flattening of the cornea.  Other

                                    -8-
<PAGE>
surgical techniques are keratomileusis, which involves freezing the cornea and
reshaping it, and automated lamellar keratoplasty ("ALK"), which involves
using a microkeratone to remove microscopic amounts of corneal tissue. 
Industry sources estimate that 200,000 RK procedures were performed in the
United States in 1994.  Because RK is a manual procedure and not performed
with a computer-controlled device, RK is highly dependent on the surgical
skill of the ophthalmologist performing the procedure.  Moreover, because RK
involves incisions into the corneal tissue, it weakens the structure of the
cornea which may have adverse consequences as patients age.  RK has never
undergone a controlled clinical study under an FDA protocol because no medical
device, other than a scalpel, is used in the procedure.  Compared to RK, the
Company believes that laser surgery involves reduced surgical risk, does not
weaken the corneal tissue, is less invasive and is less dependent on the
ophthalmologist's skill.
    
      LASER VISION CORRECTION SYSTEMS
      
      Excimer lasers are incorporated in a fully integrated ophthalmic
surgical workstation for use by ophthalmologists to perform procedures to
treat refractive and other ophthalmic disorders.  The excimer laser system
delivers pulses of ultraviolet laser light to ablate (remove) submicron layers
of tissue from the surface of the cornea in a computer-assisted, predetermined
pattern to reshape the cornea.  Most of the laser light generated by the
excimer system is absorbed by the removed corneal tissue during a procedure. 
As a result, the laser light does not penetrate interior portions of the eye
and does not create substantial amounts of heat in the surrounding tissue. 
These attributes make the excimer laser system well suited to corneal surgery.

      Advanced LVC equipment supplied by various manufacturers has been
commercially available since approximately 1990 for use in foreign countries,
including Canada and various countries in Europe, among others.  Two U.S.
manufacturers, Summit and VISX, received pre-market approval from the FDA in
October 1995 and March 1996, respectively, for use of excimer laser systems to
perform photorefractive keratectomy ("PRK") to treat low to moderate myopia
(nearsightedness).   PRK is a form of LVC treatment involving the use of an
excimer laser to reshape the cornea, thereby adjusting refractive power of the
eye.  Excimer lasers manufactured by Summit and VISX have also been approved
for use in the United States and other countries to treat a number of
pathological superficial corneal disorders in a procedure called
phototherapeutic keratectomy ("PTK").

      Other LVC procedures exist and are currently approved for use with
lasers outside of the United States that have not received pre-market approval
by the FDA as of the present date.   These include the use of excimer lasers
to perform a procedure known as laser in situ keratomileusis ("LASIK") and
holmium lasers for laser thermalkeratoplasty ("LTK") and laser sclerostomy
("LS") procedures.  LASIK is primarily prescribed for treatment of hyperopia
(farsightedness), astigmatism and extreme myopia;  LTK may be prescribed for
instances of mild hyperopia and astigmatism; and LS is used for treatment of
symptoms of glaucoma.  In May 1996, the FDA advised U.S. eye care
professionals that LASIK and bilateral surgery (treatment of both eyes at the
same time) are outside the scope of currently FDA approved labeling for
excimer lasers; although the FDA noted that physician discussions with
patients and decisions to conduct either of those procedures are considered
the practice of medicine outside of the direct scope of FDA regulation, the
FDA cautioned that it expects excimer laser equipment manufacturers and health
care practitioners to advertise and promote the use of FDA approved lasers in
the United States only within the scope of their FDA approved use, i.e.
currently for PRK and PTK.

      All of these LVC procedures are normally performed on an outpatient
basis and require from 15 to 30 minutes in addition to pre-operative
consultations and post-operative care. Depending upon the severity of the
patient's pre-treatment vision disorder, improved vision resulting from LVC
procedures either eliminates or significantly reduces the patient's need to
wear eyeglasses or contact lenses.

                                    -9-
<PAGE>
      Physicians associated with Vista's operating subsidiaries to date have
focused primarily on PRK treatment to correct low and mild myopia.  Vision
care professionals associated with Vista and its operating subsidiaries are
also trained in other LVC procedures, establish medical and operational
standards relating to LVC Services and train other ophthalmologists and
optometrists.

      EXCIMER LVC SYSTEMS AND PROCEDURES

      PRK:     Photorefractive keratectomy ("PRK") is a procedure performed
with a excimer laser system to treat primarily nearsightedness. When
performing PRK with the excimer laser, the ophthalmologist determines the
exact correction required (which is measured by the same type of examination
used to prescribe eyeglasses or contact lenses) and programs the correction
into the system's computer.  The ophthalmologist removes the thin surface
layer of the cornea (the epithelium) and positions the patient for the laser
procedure.  The average PRK procedure consists of approximately 150 laser
pulses, each of which lasts several billionths of a second over a period
ranging for 15 to 40 seconds.  Cumulative exposure to the laser light is less
than one second.  The entire procedure, including patient preparation and
post-operative dressing, generally lasts no more than thirty minutes.     

      Following the PRK procedure, the ophthalmologist may prescribe topical
pharmaceuticals to promote corneal healing and to alleviate discomfort.  A
series of patient follow up visits is scheduled with the ophthalmologist or an
optometrist to monitor the corneal healing process, to verify that there are
no complications and to test the correction achieved by the PRK procedure.  

      Patients undergoing PRK generally experience discomfort for
approximately 24 hours, and blurred vision for approximately 48 to 72 hours
after the procedure.  Although most patients experience improvement in
uncorrected vision within a few days of the procedure, it generally takes from
two to six months for the correction to stabilize and for the full benefit of
the procedure to be realized.  An individual typically has one eye treated in
a session, with the second eye treated three to six months thereafter.

      Although a patient usually experiences a substantial improvement in
clarity of vision within a few days following the PRK procedure, it generally
takes from two to six months for the full benefit of the procedure to occur. 
The PRK procedure is used primarily to correct the vision of patients with
myopia (or nearsightedness) ranging from -1.5 to up to -7.00 diopters,
although the PRK procedure has also been performed in foreign countries on
higher diopter nearsighted and, occasionally, farsighted and astigmatic
patients.  Approximately 90% of all myopic patients are nearsighted up to
- -6.00 diopters and use of the PRK procedure to correct the vision of
nearsighted patients of up to -6.00 diopters therefore has received the
greatest degree of testing.

      LASIK:     Laser assisted in situ keratomileusis ("LASIK") is a
procedure performed with an excimer laser system primarily to treat extreme
cases of myopia.  LASIK, although a more unusual and delicate surgical
procedure than PRK, offers advantages in that the epithelium is not touched by
the laser and therefore promotes quicker healing.  The ophthalmologist uses a
microkeratone to open a flap on the surface of the cornea, laser energy is
used to ablate corneal cells on the exposed surface, and the flap is then
folded back into place.   Glare and central islands are practically
non-existent after LASIK since ablation occurs in the stroma layer (under the
surface epithelium layer).  Due to the corneal flap, subsequent retouches are
facilitated with minimal recovery time.

      LASIK may be more predictable in treating high levels of myopia, but the
LASIK procedure not been specifically approved in the United States by the
FDA.  Nevertheless, Vista believes that certain physicians in the U.S. are
performing LASIK procedures.  The FDA has cautioned eye care professionals in
the U.S. to advertise and promote the use of FDA approved lasers only within
the scope of their FDA approved use, i.e. currently for PRK and PTK.

                                   -10-
<PAGE>
      PTK:     Phototherapeutic keratectomy ("PTK") is a procedure performed
with the excimer system to treat corneal pathologies.  In this procedure,
submicron layers of tissue are ablated from the surface of the cornea in order
to remove diseased, scarred or sight-inhibiting tissue.  The goal of PTK is
not necessarily to cure the corneal pathology, but to alleviate symptoms
associated with the pathology.  The FDA granted pre-market approvals for use
in the United States of PTK procedures with Summit excimer laser equipment in
February 1995 and for VISX equipment in October 1995.

      OTHER:     Excimer lasers may also be used to treat glaucoma by a
procedure known as Partial Excimer Traheculectomy ("PET").   The PET procedure
involves the use of the excimer laser to create a penetrating filter through
the scleral tissue (the tough, fibrous tissue covering all of the eye except
the cornea), which causes the permeation of fluids from within the eye, thus
reducing pressure levels.  Vista believes that one laser manufacturer has
received an Investigational Device Exemption from the FDA to conduct clinical
trials for the PET procedure in the United States.

      HOLMIUM LVC SYSTEMS AND PROCEDURES

      LTK:     Another recently developed LVC technology is the holmium laser
system.  The holmium system delivers high intensity pulses of infra red light
to an eye by means of a fiber optic cable and a single-use, hand-held probe
that directly contacts the eye at the exact spots chosen by the
ophthalmologist.  Vista is aware of two manufacturers that have developed
holmium laser systems.  Vista believes that both of those companies are in the
process of conducting clinical trials for the FDA to demonstrate the safety
and efficacy of the holmium laser to perform laserthermal keratoplasty
("LTK").   LTK is a refractive procedure performed to treat farsightedness and
astigmatism in which peripheral corneal tissue is thermally shrunk, causing
the central portion of the cornea to steepen. 

      LS:     Laser Sclerostomy ("LS") is a surgical procedure performed with
the holmium system to treat the symptoms of glaucoma by making an opening in
the front chamber of the eye.  Summit has received FDA pre-market approval to
sell its holmium system in the U.S. for treatment of glaucoma.

      OTHER LASER SYSTEMS

      Vista is aware of three companies that have reportedly developed solid
state lasers, ophthalmic laser surgical systems that apply a beam of high
intensity light to remove tissue from the inside, as opposed to the surface
of, the cornea.  Solid state lasers are designed to ablate tissue inside the
cornea without violating the cornea's surface by computer guiding the laser
beam to the inner corneal tissue and vaporizing the targeted tissue. Solid
state lasers have not been approved for use in the United States and the
Company believes these systems are still in the development stage.

BUSINESS OF VISTA

      Vista's LVC Services are conducted by three operating subsidiaries,
Vista Vision S.p.A. based in Italy ("Vista-Italy"), Vista Vision Scandinavia
A.B. based in Sweden ("Vista-Sweden"), and Vista Laser Centers of the
Southwest, Inc. based in Arizona ("Vista-Southwest").   European operations of
Vista-Italy and Vista-Sweden are operated under the trade name and style of
Vista Vision(SM) centers and North American operations are currently conducted
under the trade name and style of Icon Vision Laser Centers(SM).

      As of March 31, 1997, Vista owned approximately 74.73% of Vista-Italy
which operates three LVC centers in Italy; 100% of Vista-Sweden which operates
two LVC centers in Sweden; and 94% of Vista-Southwest which operates one
center in Arizona.   All of these LVC facilities operated for the full fiscal
year ended March 31, 1997 except that the Arizona center was established in
May 1996 and one of the Italian centers was opened in July 1996.  A center
formerly operated by a joint venture subsidiary in England was closed in June
1995 and Vista-Italy discontinued its Pisa center in May 1996.

      REVENUE RECOGNITION

      Vista's operating subsidiaries derive revenues by billing physicians at
the time of equipment use, with such fees normally based upon a negotiated
fixed fee per LVC procedure or a negotiated percentage of the gross procedure
fees charged to patients by the physician.  Physicians generally charge
patients for their services on gross procedure fee basis (each eye and the
related pre-operative and post-operative care and any corrective adjustment
representing one procedure), and the gross procedure fee is required by law to
be established by the health care professional.  However, to insure recovery
of estimated costs of operations and a reasonable margin, Vista's prior
consent is required if the physician desires to charge less than a stated
minimum gross procedure fee where Vista's revenue is based upon a percentage
of that fee as opposed to a fixed amount.

      The gross procedure fee is generally defined to include all charges to
the patient for services of one or more professionals to perform an LVC
procedure for one eye, which typically includes professional services for the
procedure, post-operative care and re-operative care procedures, if required,
plus all charges to the patient for equipment use, medical supplies and
related items.  The gross procedure fee is influenced by various factors such
as competitive pricing for LVC procedures in the relevant market, the
experience of the physician and by special requirements for each patient's
condition.  Generally speaking, gross procedure fees charged by professionals
for PRK treatment currently range from approximately $1,400 to $1,600 per eye
in the United States and from approximately $1,000 to $1,750 per eye in
Europe, although there can be no assurance these levels will be maintained for
the long term.

      Fees charged in turn by Vista to individual physicians may vary
depending upon the skill and experience of the physician, the volume of his or
her anticipated use of LVC equipment and services offered by Vista, the
individual policies of each operating center and competitive conditions in the
local market.  Such policies and methods may be changed from time to time,
which could adversely affect the amount of revenues generated.

                                   -12-
<PAGE>
      During the fiscal year ended March 31, 1997, revenues payable to
Vista-Italy and Vista-Sweden generally averaged $900 and $1,750 per procedure,
respectively, and most of these fees were based on a fixed fee per procedure
basis.  Certain operating expenses of Vista-Italy and Vista-Sweden under
cooperative agreements for use of facilities and equipment use are in turn
based upon the number of procedures performed.  Generally, the average per
procedure fees realized by Vista in Italy and Sweden during the fiscal year
ended March 31, 1997 were approximately 10% above the average per procedure
fees earned in the prior fiscal year.

      Fees payable to Vista-Southwest during the fiscal year ended March 31,
1997 generally ranged from $750 to $1,000 per procedure and were based on a
percentage, typically 60%, of the gross procedure fee charged by the
physician.

      Payment is usually collected in cash or by credit card before the
procedure is performed; however certain of Vista's European operations
commenced a program during 1996 to offer extended payment terms if the
patient's credit is approved.

      Health insurance providers generally consider LVC procedures to be
elective surgery and do not provide insurance or other third-party
reimbursement.

      RELATIONS WITH PROFESSIONALS

      Vista maintains consulting arrangements with certain professionals
experienced in LVC care to advise Vista as to current developments in surgical
procedures and technology developments, establishing ethical and operating
standards and for assistance in training other health care professionals.

      Dr. J. Charles Casebeer, formerly a director of Vista, acts as a
consultant to Vista's Vista-Southwest subsidiary operations (see "Other
Vista-Southwest Transactions with Affiliates" below).     

      LVC EQUIPMENT

      Vista is not involved in the research, development or manufacture of
refractive laser systems, and is dependent on unrelated manufacturers for the
supply of laser equipment and systems.  Vista believes there are four U.S.
companies that have conducted or are conducting clinical trials with excimer
lasers for refractive surgery: in addition to Summit and VISX, these include
Chiron Corp. and LaserSight Incorporated.   Summit and VISX have received FDA
pre-market approval to commercially sell and market in the United States their
excimer lasers for PRK treatment of low and mild myopia and for PTK
procedures.

      The current cost of an excimer laser ranges from approximately $475,000
to $525,000, plus sales tax. For laser equipment purchased from VISX or
Summit, the manufacturer generally requires an additional royalty equal to
$250 per PRK procedure to be paid to Pillar Point Partners, a partnership
between VISX and Summit that holds certain patent rights with respect to their
excimer laser technology.  The purchase price typically includes a one or two
year warranty on all parts except the optics (mirror and glass components)
which generally carry a 30-day warranty. Annual maintenance and service fees
are contracted for separately at the time of purchase and range from
approximately $40,000 to $60,000 per year, but these estimates may vary with
usage. Due to the equipment cost, Vista believes that most ophthalmologists
interested in LVC surgery will not be able or willing to purchase a laser,
seek financing for the purchase and/or arrange for required maintenance of the
laser equipment.

      Vista's European subsidiaries currently own or lease and maintain five
VISX excimer lasers.  Vista-Southwest leases a VISX excimer laser.  The
Company has one laser in storage due to newer technology, the cost of which
was written off in the fiscal year ended March 31, 1996 in the amount of
$446,636 for the impairment of an idle asset.

                                   -13-
<PAGE>
      MARKET POTENTIAL FOR LVC SERVICES

      It is estimated that in excess of 100 million people in the U.S., and a
much larger number worldwide, use eyeglasses or contact lenses to correct
common vision disorders, with over 60 million of these individuals suffering
from nearsightedness. U.S. consumers spent an estimated $13.8 billion in
eyeglass and contact lens purchases in 1993.  While excimer laser procedures
can treat people who are farsighted or are astigmatic, both the existing
technology and application for regulatory approvals for those uses are in an
earlier stage than for use of excimer lasers for treatment for
nearsightedness.

      Refractive disorders generally are corrected with conventional methods
such as eyeglasses and contact lenses. Alternative treatments for permanently
reshaping the cornea to relieve nearsightedness, farsightedness and
astigmatism include surgical methods, the most popular of which has been RK,
discussed earlier in this Report. RK is used primarily to correct
nearsightedness, but is known to have potential limitations such as: 
(i)weakening the cornea, (ii) potential for infection and (iii) producing
inconsistent visual correction results. However, RK procedures are generally
substantially less expensive than LVC procedures.   Vista believes that the
market potential for alternative refractive care utilizing excimer laser
systems is commercially significant. Many eyeglass or contact lens wearers are
potential candidates for laser refractive surgery. Generally speaking, Vista
believes that younger persons are more apt to elect refractive surgery than
older people who have become accustomed to eyeglasses or contact lenses over
an extended period.  However, the degree to which Vista's LVC Services can
penetrate the potential market for vision correction will depend on a variety
of factors including, but not limited to, medical and public acceptance of
laser vision correction procedures and alternative technologies. None of these
factors is under the immediate control of Vista nor is any predictable at this
time.

      FDA PRE-MARKET APPROVAL OF LVC EXCIMER SYSTEMS

      Excimer laser systems are regulated as medical devices by the United
States Food and Drug Administration ("FDA") and require pre-market clearance
or pre-market approval (referred to as a "PMA") by the FDA prior to commercial
sale and use in the U.S. Medical devices in the U.S. are classified into one
of three classes on the basis of the controls deemed necessary by the FDA to
reasonably ensure safety and effectiveness. Class III devices, which include
medical lasers, generally are those which must receive PMA by the FDA to
ensure their safety and effectiveness and include, among other devices, new
devices which have been found not to be "substantially equivalent" to existing
legally marketed devices.

      A PMA application must be supported by valid scientific evidence which
typically includes extensive preclinical and clinical trial data to
demonstrate the safety and effectiveness of the device. If human clinical
trials of a device are required, and the device presents a "significant risk,"
the sponsor of the trial (usually the manufacturer or distributor of the
device) will have to file an Investigational Device Exemption
("IDE")application prior to commencing human clinical trials. The IDE
application must be supported by data, typically including results of animal
and laboratory testing. If the IDE application is approved, human clinical
trials may begin at a specific number of investigational sites with a specific
number of patients, as approved by the FDA.

      A PMA application must contain the results of clinical trials, the
results of all relevant bench tests, laboratory and animal studies, a complete
description of the device and its components, a detailed description of
methods, facilities and controls used to manufacture the device and certain
other information. FDA review of a PMA application generally takes one to two
years from the date the PMA is accepted for filing, but may take significantly
longer.  The review time is often significantly extended by the FDA asking for

                                   -14-
<PAGE>
more information, including additional clinical trials for clarification of
information provided in the submission.  When conditions have been fulfilled
to the satisfaction of the FDA, it will issue a PMA approval letter,
authorizing commercial distribution of the device for certain applications. 
If the FDA's evaluation is not favorable, the FDA will deny approval of the
PMA application or issue a "not approvable letter".  There are devices for
which FDA approval has been sought which have never been approved for
marketing in the U.S. The FDA may approve a device for some procedures but not
others, or for certain classes of patients and not others. Modifications to a
device that is an approved PMA also may require approval by the FDA of PMA
supplements or new PMAs.

      SAFETY AND EFFICACY

      The first PRK procedure for the treatment of nearsightedness using an
excimer laser system was performed in 1989, and the first PTK procedure for
the treatment of a corneal pathology using an excimer system was performed in
1988.  A large majority of PRK and PTK procedures to date have been performed
only since 1990.  PRK to correct myopia has been performed in at least 35
countries outside the U.S. prior to 1996.

       Some potential medical risks have been identified in connection with
the use of LVC surgery and there may be other risks which will not be known
until the procedure has been more widely used and monitored over an extended
period of time.

      Possible concerns with respect to the safety and efficacy of LVC excimer
laser systems for refractive surgery include predictability and stability of
results and potential complications, such as modest decreases in best
corrected vision and side effects from PRK, PTK, LASIK and LTK. Other possible
effects include postoperative discomfort; corneal haze during healing (an
increase in the light scattering properties of the cornea); glare/halos
(undesirable visual sensations produced by bright lights); decrease in
contrast sensitivity (diminished vision in low light); temporary increases in
intraocular pressure in reaction to post procedure medication; modest
fluctuations in astigmatism and modest decreases in best corrected vision
(i.e., with eyeglasses); unintended over or under corrections; instability,
reversal or regression of effect; corneal scars (blemishing marks left on the
cornea); corneal ulcers (inflammatory lesions resulting in loss of corneal
tissue); and corneal healing disorders (compromised or weakened immune system
or connective tissue disease which causes poor healing).

      Summit has reported that two year follow-up data accumulated by Summit
during its Phase III PRK clinical trials indicate all of the individuals
undergoing PRK experienced an improvement in visual acuity without corrective
eyewear. Prior to PRK, 95% of the eyes in this group were 20/200 or worse. Of
the eyes treated, approximately 91% improved to 20/40 or better, the legal
requirement to obtain a driver's license in most states without corrective
eyewear, while the remaining 9% experienced improved vision without corrective
eyewear, but still required corrective eyewear to achieve 20/40 vision or
better.

      GOVERNMENTAL REGULATION

      The manufacturing, labeling, distribution, marketing and promotion of
medical devices such as excimer lasers to which Vista and its affiliated
companies provide access are subject to extensive and rigorous government
regulation in the United States and in certain other countries.

      Excimer lasers in the United States are required to be the subject of an
approved PMA application. Summit and VISX have received approval of PMA
applications for use of their excimer lasers in PRK and PTK procedures for the
treatment of low to mild myopia.  There can be no assurance that FDA approval
will be received by equipment manufacturers for use of PRK for other
refractive disorders, such as extreme myopia, astigmatism and

                                   -15-
<PAGE>
hyperopia (farsightedness) or that other LVC procedures, such as LASIK, will
ever be approved by the FDA.  Failure to receive such approvals could have the
effect of limiting the market for LVC procedures in the United States.

      Users of medical devices in the United States are subject to continuing
FDA obligations. Medical devices are required to be manufactured in accordance
with regulations setting forth current Good Manufacturing Practices ("GMP"),
which require that devices be manufactured and records be maintained in a
prescribed manner with respect to manufacturing, testing and control
activities.  It is the FDA's view that with respect to excimer lasers, users,
as well as manufacturers, are required to comply with FDA requirements with
respect to labeling and promotion.  The Medical Device Reporting regulation
adopted by the FDA would require that the user provide information to the FDA
whenever there is evidence to reasonably suggest that one of its devices may
have caused or contributed to a death or serious injury, or that there has
occurred a malfunction that would be likely to cause or contribute to a death
or serious injury if the malfunction were to recur.  Users of medical devices
are subject to periodic inspections by the FDA.  Failure to comply with
applicable FDA requirements could subject one or more Regional Joint Ventures
subject to FDA regulation in the United States to enforcement action,
including product seizures, recalls, withdrawal of approvals, and civil and
criminal penalties, any one or more of which could have a material adverse
effect.

      Medical device laws and regulations are also in effect in Europe and
other foreign countries.  These range from comprehensive device approval
requirements to requests for product data or certifications.  The number and
scope of these requirements are increasing.  The failure of Vista's European
operating subsidiaries to comply with applicable foreign medical device laws
and regulations may have a material adverse effect on the Company's business.

      Federal, state and foreign laws and regulations regarding the
manufacture and marketing of medical devices are subject to change.  For
example, the FDA is currently considering significant changes to its GMP and
to other regulations. Vista cannot predict what impact, if any, such changes
might have on its business.

      The operations of Vista's subsidiaries are also subject to extensive
rules and regulations, both in the United States and foreign countries at the
federal, provincial, state and local level, affecting the health care industry
and the delivery of health care.  These include laws and regulations
prohibiting the practice of medicine and optometry by persons not licensed to
practice medicine or optometry, prohibiting the unlawful rebate or unlawful
division of fees and limiting the manner in which prospective patients may be
solicited.

      Current regulatory requirements and restrictions that relate to
corporate entities involved in the ownership and operation of healthcare
facilities include prohibitions against: the corporate practice of medicine
except by an entity owned by healthcare professionals and/or wherein the
professionals exercise control over medical judgments; patient referrals by
healthcare professionals (including ophthalmologists and optometrists) to a
facility owned or compensated by such referring professional (either
generally, or sometimes by defining such payments as "kick backs"); and "fee
splitting" between healthcare professionals and corporate entities.  Other
laws in both the United States and foreign countries specifically regulate the
nature and compensation provisions of employment or management relationships
that healthcare professionals may have with a corporate-owned facility, may
affect the form of business entity to be utilized, may limit payments either
to the entity or to healthcare professionals to the "fair market value" of
their contributions, or affect the manner of marketing the service performed
at the healthcare facility.  Additional regulations in some jurisdictions also
now affect, or in the future may affect, the administration and use of LVC
Services, including requirements for certificates of need and/or other
licensing and registration of medical equipment.

                                   -16-
<PAGE>
      Laws and regulations affecting the manner in which LVC Services may be
marketed, administered or compensated for vary significantly from jurisdiction
to jurisdiction.  In some instances these laws and regulations are ambiguous,
and sometimes regulators fail to provide adequate guidelines. Vista believes
that its operating subsidiaries have adopted strategies that enables each of
them to offer and administer LVC Services in compliance with applicable
regulatory requirements in their areas of operations.  However, federal, state
and foreign regulatory attention may continue to be directed to the practice
of medicine, and any changes in applicable law or regulations, or in
governmental agency and judicial interpretations of such laws and regulations,
could cause one or more of these strategies currently in compliance with
applicable laws to cease to comply.

      The use of excimer lasers and other medical equipment is also subject to
numerous government laws and regulations relating to such matters as safe
working conditions, environmental protection, fire hazard control and disposal
of potentially hazardous substances.

      INSURANCE AND INDEMNIFICATION

      Health insurance providers in the United States generally consider LVC
procedures to be elective surgery and do not provide insurance reimbursement.
In other countries, reimbursement programs vary by country and region, and
reimbursement is not generally available for locations at which Vista's
European subsidiaries currently operate.

      Use of laser systems by health care professionals using laser equipment
and other LVC Services may give rise to claims against Vista or its affiliates
by persons alleging injury.  Vista's subsidiaries generally do not currently
have malpractice liability insurance due to limited capital resources.

      Vista believes that claims alleging defects in laser systems will be
covered by manufacturers' warranties and the manufacturer's product liability
insurance, and that Vista and its affiliates could take advantage of such
insurance by adding such suppliers to potentially adverse lawsuits. There can
be no assurance that laser suppliers will carry product liability insurance or
that any such insurance will be adequate to protect Vista.

      Generally speaking, the policy of Vista's operating subsidiaries and
Regional Joint Ventures are to require that ophthalmologists who perform laser
procedures by use of LVC equipment maintain their own professional liability
insurance.  There can be no assurance that such insurance will be adequate to
cover claims asserted against Vista, in which event Vista's business may be
materially adversely affected.  

      PROPRIETARY RIGHTS

      Vista has no licenses, patents, registered trademarks or registered
copyrights.   Vista's U.S. operations have adopted the service mark" Icon
Vision Laser Centers"(SM) and its European operating subsidiaries conduct
business under the name of "Vista Vision"(SM).

      COMPETITION

      The vision care industry is extremely competitive and includes numerous
companies that are substantially larger than Vista and have greater financial,
marketing and technical resources.  Vista believes principal competitive
factors affecting revenues include market acceptance of LVC procedures by both
patients and vision care professionals, performance, success relative to
alternative refractive correction methods, pricing, regulatory requirements,
quality of equipment and convenience to the patient and physicians, some of
which are factors beyond Vista's control.

                                   -17-
<PAGE>
      Vista competes with other surgical and non-surgical forms of treatments
for refractive disorders, including eyeglasses, contact lenses, manual
refractive surgery (such as RK), corneal transplants and possibly other new
technologies currently under development.  Continued use of eyeglasses and
contact lens are expected to be the most popular methods of treating
refractive vision disorders due to low immediate cost and the avoidance of
surgery.

      The market for access to excimer lasers is highly competitive and the
Company competes in its various geographic markets with other businesses
formed since 1990 offering similar access to LVC equipment and services in
Europe, Canada and the United States.  These competitors are pursuing a
variety of business and marketing strategies, such as marketing directly to
consumers through optical chains or affiliating with hospitals or physician
group practices.  Other companies which currently provide access to laser
equipment include: Beacon Eye Institute Inc.;  Refractive Centers
International, Inc.; Vision International, Inc.; Laser Vision Centers, Inc.;
Global Vision, Inc.; Sight Resources, Inc.; Sterling Vision, Inc.; The Laser
Centre; 20/20 Laser Centers, Inc.; and LCA Vision, Inc.  Additional
competition also exists or may develop from hospital affiliated groups,
physician group practices and private ophthalmologists electing to purchase
refractive laser systems, some of whom are believed to operate equipment for
which royalties are not payable to a laser manufacturer.

      The ability of Vista and its Regional Joint Ventures to compete
successfully may also depend in the future on their ability to adapt to
technological changes and advances in the treatment of refractive vision
disorders. There can be no assurance that, as the market for excimer laser
surgery and other treatments of refractive disorders develops, that equipment
owned and/or leased by Vista and its affiliates will not become obsolete, and
if this occurs, there can be no assurance that Vista will be able to secure
new equipment to allow Vista and its affiliates to compete effectively.

FORMER INVESTMENT OF VISTA IN TECHNICAL CHEMICALS AND PRODUCTS, INC.

      As part of an agreement between Vista and ACE generating additional
financing for Vista in March 1996, Vista received 200,000 restricted shares of
Technical Chemicals and Products, Inc. ("TCPI") common stock from ACE's
predecessor at a value of $2,662,500, or $13.31 per TCPI share.  TCPI's common
stock is publicly-traded in The Nasdaq Stock Market under the trading symbol
TCPI.  At the time this transaction was completed, shares of TCPI acquired by
Vista were restricted as to resale under federal securities laws and were
valued for financial statement purposes at a 25% discount from the public
market price. 

      TCPI filed a registration statement on Form S-3 to register certain
shares of TCPI common stock, including the 200,000 shares owned by Vista.  The
resale of these shares pursuant to such registration was subject to a lock-up
agreement.  Under that lock-up, Vista agreed it would not sell, contract to
sell, grant any option for the sale of, or otherwise directly or indirectly
dispose of Vista's shares of TCPI common stock during the period expiring 180
days following the closing of a public offering of securities by TCPI on May
2, 1996 without the prior consent of the representative of the underwriters of
TCPI's public offering.  Vista sold most of its TCPI Shares in late November
1996 at prices ranging from $7.50 to $8.00 per share.

TRANSACTIONS RELATING TO VISTA-SOUTHWEST AND AFFILIATES

      FINANCING AND OTHER TRANSACTIONS INVOLVING VISTA-SOUTHWEST AND VISTA

      In March, 1996, Vista issued 250,000 shares of its common stock with an
estimated value of approximately $270,500 at the date of issuance as a
subscription to 350,000 shares of Series B convertible preferred stock in
Vista-Southwest.  Effective July 18, 1996, Vista also acquired rights to
100,000 Vista-Southwest Series A preferred shares from Refractive

                                   -18-
<PAGE>
Services-800, Inc., a third party, in exchange for 100,000 shares of Vista's
common stock with an estimated value of approximately $99,000 at the date of
issuance.  A proxy to vote Vista's preferred shares in Vista-Southwest was
granted by Vista to Vista-Southwest's operating management and their
affiliates.  During the period from January 1996 to September 30, 1996, Vista
also advanced loans of $383,634 to Vista-Southwest used to finance a portion
of Vista-Southwest's requirements for operations, acquisition of equipment and
facilities, and a planned public offering of its securities.

      Vista subsequently elected to convert all of its rights to 450,000
shares of Vista-Southwest preferred stock into 450,000 shares of
Vista-Southwest common stock, and Vista-Southwest management and their
affiliates released the right to vote such shares by proxy.

      On October 1, 1996, Vista and Vista-Southwest agreed to extinguish
Vista's account receivable of $383,634 for prior advances to Vista-Southwest
in exchange for the transfer to Vista of 250,000 shares of Vista common stock
then owned by Vista-Southwest.  This transaction increased Vista's net
investment in Vista-Southwest by $145,634.  As of March 31,1997, Vista had
advanced an additional $210,846 to Vista-Southwest as additional investment in
Vista-Southwest common stock.

      As of October 1, 1996, Vista agreed to purchase a $100,000
Vista-Southwest promissory note and 10,000 Vista-Southwest Class B warrants
exercisable at $4.00 per share until March 31, 1999 from Atlantic Central in
exchange for a $100,000 note payable by Vista to Atlantic Central.  The
Company concurrently agreed with Vista-Southwest to surrender the $100,000
Vista-Southwest note for cancellation in exchange for 100,000 shares of
Vista-Southwest common stock effective October 1, 1996.

      As a result of these transactions, Vista owned 550,000 shares of
Vista-Southwest common stock, representing 94% of the Vista-Southwest
outstanding capital stock as of March 31, 1997, before giving effect to shares
Vista may acquire as a result of additional advances by Vista to
Vista-Southwest after October 1, 1996.  Vista advanced $210,846 to
Vista-Southwest during the period from October 1996 through March 31, 1997 and
an additional $120,000 during the period from April 1997 through May 30, 1997.

      Vista-Southwest abandoned a proposed initial public offering in late
1996 and abandoned a proposed private placement offering in May 1997.  As
such, the ability of Vista-Southwest to sustain its operations will be
dependent upon additional advances from Vista and/or its controlling
stockholder, Atlantic Central, until such time as Vista-Southwest achieves
sufficient cash flow from internal operations or additional capital from third
parties to support its working capital requirements, as to which there can be
no assurance.

      OTHER VISTA-SOUTHWEST TRANSACTIONS WITH AFFILIATES

      In addition to investments in Vista-Southwest by Vista, Vista-Southwest
since its inception through March 31, 1997 has sold to management and their
affiliates and to certain physicians associated with Vista-Southwest a total
of 35,000 shares of Vista-Southwest common stock at $1.00 per share ($35,000)
and 315,000 Class A warrants at $0.10 per warrant ($31,500), exercisable at $1
per share expiring on the earlier of May 15, 2000 or upon a merger of sale of
Vista-Southwest's business approved by a majority of its stockholders. 
Vista-Southwest also received $25,000 from the sale of units to an
unaffiliated third party consisting of a $25,000 in principal amount of an 11%
convertible note and 2,500 Vista-Southwest Class B common stock purchase
warrants exercisable at $4 per share expiring on March 31, 1999. 
Vista-Southwest subsequently redeemed the units issued to this unaffiliated
third party for $25,000 plus interest.

      Dr. J. Charles Casebeer, a former director of Vista from February 1996
to September 23, 1997, has served as Chairman of the Board and a director of
Vista-Southwest since its inception in early 1996.  A corporate affiliate of
Dr. Casebeer owns 17,031 shares of Vista-Southwest common stock and Class A

                                   -19-
<PAGE>
warrants to purchase up to 153,279 additional Vista-Southwest common shares at
an exercise price of $1.00 per share expiring on the earlier of May 15, 2000
or upon a merger of sale of Vista-Southwest's business approved by a majority
of its stockholders.

      Vista-Southwest entered into a Consulting Agreement dated as of July
1,1997 with Dr. Casebeer under which he agreed to provide consulting services,
attend and participate in LVC care presentations and seminars with medical
professionals and medical groups, manage training and education seminars, and
render services concerning the establishment of ethical standards and
procedures at care facilities.  Vista paid consulting payments of $5,000 per
month to Dr. Casebeer under this agreement until he resigned as a Vista
director in October 1997.  Dr. Casebeer is also entitled to receive separate
compensation as an officer of Vista-Southwest and from his patients for
performing LVC procedures and rendering other medical services to his
patients.

      Vista-Southwest entered into an Asset Purchase and Lease Assumption
Agreement with a corporate affiliate of Dr. Casebeer dated January 30, 1996
and amended on July 8, 1997 (the "Asset Agreement").  Under the Asset
Agreement, Vista-Southwest agreed to purchase an excimer laser system and
office equipment from Dr. Casebeer's corporate affiliate for a purchase price
of $75,000 in cash, a $96,591 promissory note with annual interest at
8%originally due May 31, 1996, and the assumption of outstanding obligations
under an equipment lease on the laser, including future lease payments not to
exceed $328,409.  Vista  subsequently replaced this laser with newer
technology resulting to a charge to Company's statement of operations in the
amount of $446,636 for the impairment of an idle asset.   As of March 31,1997,
$80,000 of the note payable to Dr. Casebeer's affiliate for $96,591 had been
paid and the remaining unpaid balance has been forgiven.

      Vista-Southwest also assumed real estate obligations for the lease of
its facilities in Scottsdale, Arizona from a corporate affiliate of
Dr.Casebeer as of February 1, 1996.  This lease expires on December 31, 1997
and currently provides for the lease of approximately 3,254 square feet at a
rental of $4,699 per month.  Vista-Southwest permits Casebeer-Hale
International, Inc., an affiliate of Dr. Casebeer, free use of these
facilities in connection with their medical practice.  Dr. Casebeer
compensates Vista-Southwest for use of its LVC equipment and services on
substantially the same basis as are charged by Vista-Southwest to other
physicians.

SUSPENSION OF NORTH AMERICAN EXPANSION PROGRAM AND OTHER RECENT TRANSACTIONS

      Vista developed a business strategy in June 1995 to expand its LVC
Services business in North America by organizing and sponsoring separate
corporations as regional enterprises (the "Regional Joint Ventures") in which
Vista would obtain an equity interest and long-term fee-based consulting
arrangements.  Vista planned to seek affiliations for each of its Regional
Joint Venture subsidiaries with experienced LVC eye care professionals; each
Regional Joint Venture would be expected to seek third-party financing with
Vista's assistance to provide equipment and other LVC support services to
vision care professionals in targeted regional markets operating under the
name "Vista Laser Centers" (subsequently changed to "Icon Vision Laser
Centers").

      To date, Vista-Southwest is the only Regional Joint Venture sponsored by
Vista which is operating an active business and in which Vista owns an equity
interest.  Due to former management's inability to obtain additional financing
from third parties, negotiations to affiliate Vista with physicians and
acquire existing facilities at three locations in Canada, together with
proposed third-party financing activities, have been abandoned and Vista has
disposed of its investment in another enterprise formed to develop the
Northern California market.  Accordingly, there are two Regional Joint Venture
entities owned by Vista which currently have no business operations (Vista
Laser Centers of Michigan, Inc. and Vista Laser Centers of the Northwest,

                                   -20-
<PAGE>
Inc.) and Vista has disposed of all of its interest in two other Regional
Joint Ventures entities then doing business as Vista Laser Centers of the
Northeast and Vista Laser Centers of the Pacific.

      From July 1995 through May 1996, a foreign corporate investor,
Refractive Services 800, Inc., invested $520,000 in seed capital for preferred
shares in five Regional Joint Ventures formed by Vista to finance initial
organizational expenses and costs of negotiating agreements with vision care
physicians and seeking additional financing.  Vista also made equity
investments in these five Regional Joint Ventures by issuing shares of Vista
common stock to such entities in exchange for additional preferred shares of
the Regional Joint Venture.  On July 18, 1996, Vista acquired the equity
interest owned by Refractive Services-800, Inc. in the five Regional Joint
Ventures in exchange for 520,000 shares of Vista common stock.  All of the
preferred shares owned by Vista in each Regional Joint Venture were later
converted by Vista into common stock of the respective Regional Joint Venture. 
Shares of Vista common stock issued to Regional Joint Venture entities other
than Vista Laser Centers of the Northeast subsequently were reacquired by
Vista.

      As to the four Regional Joint Ventures for which Vista has either
abandoned acquisition and related third-party financing negotiations and/or
disposed of its interest, all of Vista's net investments of $1,934,171 in such
enterprises were written off during the fiscal year ended March 31, 1997.
Vista remains contingently responsible as a guarantor of real estate and
equipment financing obligations for two of such entities in the aggregate
amount of approximately $3,035,000 at March 31, 1997 (see Notes 7(d) and 7(e)
of the Notes to Consolidated Financial Statements at March 31, 1997) and Vista
holds $260,800 in note receivables from the Pacific entity.

      Vista's management intends to reactivate a strategic expansion plan if a
debt compromise plan with Vista's creditors is proposed and accepted and if
significant additional capital is obtained; there can be no assurance that
Vista will be successful in accomplishing either of these objectives.  Pending
further developments, Vista has been advised that its controlling stockholder,
Atlantic Central, plans to pursue a strategic plan of negotiating to acquire
or develop Regional Joint Ventures in the United States for laser vision
correction facilities and services.  Vista has been advised that if ACE can
successfully implement a strategy of North American expansion in the field of
laser vision correction, it anticipates that Vista will be provided the right
to acquire such operations at ACE's cost if Vista completes a debt compromise
plan with its creditors and if significant additional capital is obtained.  

Transactions that occurred with respect to four Regional Joint Ventures
abandoned or disposed of by Vista are summarized as follows:

      INVESTMENT IN VISTA LASER CENTERS OF MICHIGAN, INC.

      In November 1995, Vista issued 200,000 shares of its common stock at an
estimated value of $217,600 in exchange for 200,000 shares of 5% Series B
convertible preferred stock in Vista Laser Centers of Michigan, Inc.
("VLC-Michigan").  Effective July 18, 1996, Vista also acquired 100,000
VLC-Michigan Series A preferred shares from Refractive Services-800, Inc. in
exchange for 100,000 shares of Vista's common stock with an estimated value of
approximately $99,000 at the date of issuance.  Vista subsequently elected to
convert all 300,000 shares of VLC-Michigan preferred stock into 300,000 shares
of VLC-Michigan common stock.

      VLC-Michigan filed documents for a proposed initial public offering in
early 1996 that was abandoned in late 1996 following a determination that VLC-
Michigan securities would not be approved for listing on The Nasdaq SmallCap
Market.  During December 1996, negotiations for VLC-Michigan to acquire an
existing laser vision correction services business based in Windsor, Ontario,
and to enter into related agreements with affiliates of the physician who
owned the Windsor business, were terminated.  VLC-Michigan accordingly

                                   -21-
<PAGE>
refunded stock subscriptions previously received from affiliates of that
physician.  Vista also caused 200,000 shares of Vista's common stock owned by
VLC-Michigan to be exchanged for the redemption of 200,000 shares of
VLC-Michigan common stock then owned by Vista and Vista agreed to assume
responsibility for refunding a $9,500 stock subscription received from Dr.
J.Charles Casebeer, a former director of Vista.  As a result of these
transactions, Vista owns all of the capital stock in VLC-Michigan which is not
currently an operating company.

      During the period from March 1996 through October 1996, there were
various advances made by Vista to VLC-Michigan for its initial public offering
expenses aggregating approximately $84,236 plus approximately $426,600 of
advances to finance equipment deposits and operating expenses of the
businesses that VLC-Michigan proposed to acquire and develop.  In November
1996, $100,000 of such cash advances was repaid to Vista.  Vista has attempted
to obtain an accounting and/or refund of the remaining $410,800 of such
advances and to date has recovered approximately $108,000.   As of March 31,
1997, the remaining $302,800 receivable has been written off.

      INVESTMENT IN VISTA LASER CENTERS OF THE NORTHWEST, INC.

      In May 1996, Vista issued 500,000 shares of its common stock at an
estimated value of $494,500 in exchange for 500,000 shares of 5% Series B
convertible preferred stock in Vista Laser Centers of the Northwest, Inc.
("VLC-Northwest").  Effective July 18, 1996, Vista also acquired 100,000
VLC-Northwest Series A preferred shares from Refractive Services-800, Inc. in
exchange for 120,000 shares of Vista's common stock with an estimated value of
approximately $118,800 at the date of issuance.  Vista subsequently elected to
convert all 600,000 shares of VLC-Northwest preferred stock into 600,000
shares of VLC-Northwest common stock.

      During October 1996, VLC-Northwest and a corporate affiliate of Dr.
Donald G. Johnson, then an officer and director of Vista, terminated
negotiations that contemplated the possible future acquisition by
VLC-Northwest of an existing laser vision correction services business from
Dr. Johnson's corporate affiliate.  Dr. Johnson subsequently resigned as
Chairman of the Board and a director of Vista in June 1997.  VLC-Northwest
refunded Dr. Johnson's original cash investment in VLC-Northwest due to the
termination of these negotiations.  Vista caused 500,000 shares of Vista's
common stock owned by VLC-Northwest to be exchanged for the redemption of
500,000 shares of VLC-Northwest common stock then owned by Vista.  As a result
of these transactions, Vista owns all of the capital stock in VLC-Northwest
which is not currently an operating company.

      During the period from August 1996 through November 1996, there were
various advances made by Vista to VLC-Northwest for its initial public
offering expenses aggregating approximately $73,000 plus approximately
$220,000 of advances to finance equipment deposits and operating expenses of
the business that VLC-Northwest proposed to acquire and develop.  In November
1996, Vista received repayment of $189,016 of such prior advances.  During
January 1997, Vista paid $4,936 to an affiliate of Dr. Johnson in
reimbursement of funds advanced for the account of VLC-Northwest. 

      As of March 31, 1997, all of the remaining $73,000 in advances and
$96,000 of Vista's equity investment in VLC-Northwest had been written off.

      INVESTMENT IN VISTA LASER CENTERS OF THE PACIFIC, INC.

      In May 1996, Vista issued 500,000 shares of its common stock at an
estimated value of $487,850 in exchange for 500,000 shares of 5% Series B
convertible preferred stock in Vista Laser Centers of the Pacific, Inc.
("VLC-Pacific").  Effective July 18, 1996, Vista also acquired 100,000
VLC-Pacific Series A preferred shares from Refractive Services-800, Inc. in
exchange for 100,000 shares of Vista's common stock with an estimated value of
approximately $99,000 at the date of issuance.  Vista subsequently elected to
convert all its 600,000 shares of VLC-Pacific preferred stock into 600,000
shares of VLC-Pacific common stock.

                                   -22-
<PAGE>
      To accommodate the request of VLC-Pacific in its efforts for a proposed
public offering of its securities, during December 1996 Vista and VLC-Pacific
mutually agreed: (i) to terminate a consulting services agreement between
Vista and VLC-Pacific; (ii) Vista accepted 500,000 shares of its common stock
owned by VLC-Pacific in exchange for the cancellation of 500,000 shares of
VLC-Pacific common stock then owned by Vista; and (iii) Vista agreed to accept
a 9% promissory note issued by VLC-Pacific in the principal amount of $100,000
for the repurchase of the remaining 100,000 shares of VLC-Pacific common stock
then owned by Vista.  VLC-Pacific also issued a 9% promissory note in the
principal amount of $160,838 to evidence its obligations for repayment of
advances in that amount by the Company to VLC-Pacific.  Each of the
VLC-Pacific promissory notes are due on the earlier of December 31, 1998 or
ten days after successful completion of an initial public offering by
VLC-Pacific.

      As a result of these transactions, Vista had disposed of all of its
equity interest in VLC-Pacific capital stock as of December 31, 1996.  The
notes receivable from VLC-Pacific are recorded on Vista's consolidated balance
sheet at an estimated realizable value of $260,838 as of March 31,1997 and its
remaining investment of $171,442 in VLC-Pacific has been written off.

      INVESTMENT IN VISTA LASER CENTERS OF THE NORTHEAST

      In May 1996, Vista issued 450,000 shares of its common stock at an
estimated value of $445,500 in exchange for 500,000 shares of 5% Series B
convertible preferred stock in Vista Laser Centers Metro Inc., subsequently
doing business as Vista Laser Centers of the Northeast ("VLC-Northeast").
Effective July 18, 1996, Vista also acquired 100,000 VLC-Northeast Series A
preferred shares from Refractive Services-800, Inc. in exchange for 100,000
shares of Vista's common stock with an estimated value of approximately
$99,000 at the date of issuance.

      In January 1997, Vista, ACE's predecessor, VLC-Northeast and certain
members of VLC-Northeast operating management and their affiliates entered
into a settlement agreement to terminate all relationships between the
parties.  Vista sold all of its equity investment in VLC- Northeast for the
sum of $1.00 and agreed to assign to a non-related entity for the sum of $1.00
all prior advances and loans by Vista to VLC-Northeast in the aggregate amount
of $511,460.  Vista further agreed: (i) to pay $50,000 as a settlement of
prior obligations to VLC-Northeast; (ii) to pay VLC-Northeast an amount equal
to $75,000 plus $6,271 in interest accrued on certain promissory notes
previously issued by VLC-Northeast to ACE's predecessor (and secured by a
pledge of certain shares of Company common stock owned by VLC-Northeast),
against the receipt from Atlantic Central of releases in favor of Vista and of
all collateral security claims to shares of Vista's common stock owned by
VLC-Northeast; (iii) to advance $50,000 to an escrow fund for use by VLC-
Northeast under prescribed conditions for expenses relating to its future
capital-raising expenses, which advances were to be repaid to Vista in the
event VLC-Northeast completed additional debt or equity financings in the
aggregate amount of at least $500,000; and (iv) to pay $275,000 (of which
$200,000 was to be deposited into an escrow account) from proceeds of a
financing of at least $2 million by Vista.

     VLC-Northeast agreed to release its license to use Vista's service marks,
to change the name of VLC-Northeast and signage to eliminate use of the
"Vista" name by VLC-Northeast (subject to a non-assignable license to VLC-
Northeast for use of certain promotional and marketing materials of the
Company within the greater Toronto, Ontario area so long as such materials do
not use the word "Vista" or Vista's associated logo), and to return for
cancellation 450,000 shares of Vista's common stock currently owned by
VLC-Northeast at the time all escrow funds were deposited by Vista.  Of the
$200,000 in funds to be deposited into an escrow account, $50,000 was to be
released to VLC-Northeast upon completion of actions necessary for termination
of its use of the name "Vista" and Vista's service marks by July 1, 1997, and

                                   -23-
<PAGE>
the remaining $150,000 was to be released to VLC-Northeast at the rate of
$25,000 per month, except that any undisbursed escrow funds were to be
refunded to Vista in the event VLC-Northeast completed additional debt or
equity financings in the aggregate amount of at least $500,000.

      Vista paid $150,000 under the settlement and will be obligated to
deposit an additional $275,000 from proceeds of any private placement offering
of at least $2 million by Vista.  Vista has also agreed to remain obligated as
a guarantor of certain equipment lease and premises lease obligations of
VLC-Northeast aggregating approximately $1,605,000 as of March 31, 1997,
subject to the agreement of VLC-Northeast to use its best efforts to obtain a
release of such guarantees in the event of a change in control of
VLC-Northeast or should Vista successfully complete a private placement
offering of at least $2 million, failing which VLC-Northeast will agree to
indemnify Vista for any liabilities incurred as a result of the guarantees.

      As a result of these transactions, Vista did not own an equity interest
in VLC-Northeast capital stock and has written off its investments in
VLC-Northeast as of March 31, 1997.

      The obligation of VLC-Northeast to return 450,000 shares of the
Company's common stock for cancellation was contingent upon Vista's payment of
$275,000 from proceeds of a private placement offering of at least $2 million
by Vista.  Negotiations by Vista to obtain private placement financing pending
at the time of its settlement agreement with VLC-Northeast were subsequently
abandoned, and VLC-Northeast has claimed that it has no obligation to return
the 450,000 shares to Vista. 

EMPLOYEES

      ACE's corporate offices, as of February 28, 1998, employ the services of

ITEM 3.     LEGAL PROCEEDINGS

VISTA LITIGATION WITH FORMER EXECUTIVE OFFICERS

      In June 1997, Vista was named as the defendant in a civil action
entitled Thomas A. Schultz and Allen J. Simon vs. Vista Technologies Inc.,
filed in the Superior Court of the State of California, Santa Clara County,
case number CV766644.  The complaint alleges that Vista breached written
employment agreements with each of the two plaintiffs, both of whom were
terminated as employees of Vista on March 6, 1997, and seeks damages of
$231,073 plus interest and costs for Thomas A. Schultz, damages of  $241,902
plus interest and costs for Allen J. Simon, and restoration of stock options
previously issued to the plaintiffs under the terms of their employment
agreements.

      Vista's written employment agreement with Thomas A. Schultz was dated
January 31, 1996 and subsequently amended.  Mr. Schultz was elected President

                                   -25-
<PAGE>
and Chief Executive Officer of Vista on February 16, 1996.  His employment
agreement provided he would be entitled to severance benefits if his
employment was involuntarily terminated, other than for cause, death or
disability, equal to (i) a lump-sum payment equal to his annual base salary of
$175,000, (ii) continuation of insurance benefits for life, health, dental and
long-term disability for a period of 12 months after employment termination,
and (iii) continued vesting of his outstanding stock options for a period of
12 months after employment termination.  Vista's written employment agreement
dated November 1, 1996 with Allen J. Simon, who was elected Vista's Executive
Vice President and Chief Operating Officer on November 11, 1996, provided he
would be entitled to severance benefits if his employment was involuntarily or
constructively terminated, other than for cause, death or disability, equal to
(i) a lump-sum payment equal to his annual base salary of $175,000, and (ii)
continuation of insurance benefits for life, health, dental and long-term
disability for a period of 12 months after employment termination.

      Vista intends to vigorously contest claims of the plaintiffs for damages
based upon Vista's claim that their employment was terminated for cause. 
However, these proceedings are at a preliminary stage and no discovery has
taken place.  Special counsel engaged to represent Vista accordingly has
advised it cannot render an opinion as to whether the likelihood of an adverse
determination would be remote, reasonably possible or probable, until
discovery proceedings have been conducted.  Vista has established a reserve
for these legal proceedings, but an adverse determination in these proceedings
would have a material adverse effect on the current financial condition of
Vista.

LEGAL PROCEEDINGS AS TO VISTA-ITALY

      In view of an adverse judgment entered in December 1993 in the Circuit
Court of St. Louis County, Missouri against Vista-Italy in favor of
LaserVision Centers, Inc. ("LVCI"), Vista has recorded an accrued liability of
$175,000 on its consolidated balance sheet for damages awarded against
Vista-Italy by the judgment.  Attempts by Vista-Italy from 1994 through
November 1996 to vacate the judgment and appeal the decision in Missouri state
courts were unsuccessful.

      In March 1997, LVCI instituted legal proceeding in Italy to enforce
collection of the judgment entered by the Missouri court.  Vista-Italy intends
to contest these proceedings on the basis that the Missouri default judgment
is not entitled to enforcement in Italy and Vista-Italy is exploring the
possibility of asserting counterclaims.  These proceedings in Italy are in the
preliminary stages, and special counsel engaged to represent Vista-Italy has
advised it cannot yet render an opinion as to whether the likelihood of an
adverse determination would be remote, reasonably possible or probable.  As
noted above, Vista has established a reserve for these legal proceedings and
an adverse determination in these proceedings would not have a material
adverse effect on the financial condition of Vista-Italy.

FRAUDULENT SHARE ISSUANCES AND LEGAL PROCEEDINGS AGAINST FORMER COUNSEL 

      On December 12, 1997, management of the Company discovered that one of
its former U.S. counsel fraudulently caused 960,000 newly issued and freely-
tradeable shares of the Company's common stock to be issued to his affiliate
or to his brokerage account in Canada during the period from March 25, 1997
through July 31, 1997 without the prior authorization or knowledge of the
Company's board of directors and management.  The Company's current legal
counsel believes that it is probable the Company will incur a loss contingency
for the 960,000 shares of its common stock fraudulently issued without
consideration at the sole instructions of former counsel.  The Company has
assigned a value of $400,000 for the 960,000 shares fraudulently issued and
will charge operations with the value calculated using the market value on the
day the shares were issued.

      The Company has instituted civil legal proceedings seeking a judgement
for compensatory damages in the amount of approximately $750,000 in legal fees

                                   -26-
<PAGE>
and costs paid by the Company to its former counsel during the period from
1993 to 1997 while he fraudulently represented himself to be a licensed
attorney, damages for the 960,000 fraudulently issued shares of the Company's
common stock, and other compensatory, punitive and exemplary damages.    The
Company also intends to seek the return and cancellation of the 960,000 shares
or other restitution equivalent to the estimated fair value of the 960,000
shares.
      
      Based upon extensive investigation of documents and other information
provided to current counsel with respect to these proceedings, it is the
Company's counsel's opinion that the Company has meritorious causes again its
former counsel and that it is probable the Company ultimately will be
successful in obtaining final judgments in the Company's favor against former
counsel for an amount in excess of $1,250,000.  The ability of the Company to
realize on any such judgements, if successfully obtained, will be dependent
upon the Company's ability to locate and levy upon assets of the former
counsel.  At hearings held in December 1997 and January 1998, orders of
preliminary injunction were issued by a U.S. Federal district court and a
court in British Columbia restraining the transfer of assets from accounts
with any financial institutions maintained by its former counsel and certain
corporate entities controlled by him.  Pursuant to those orders, approximately
$220,000 of cash and securities in accounts maintained by the former counsel
have been frozen and have subsequently been delivered to the Company for
liquidation. 

      The Company also is investigating potential claims against other third
parties than may have aided and abetted its former counsel with respect to one
or more of the causes of action asserted by the Company in the pending
litigation proceedings.  In addition to the former counsel and two entities
believed to be under his control, the Company's transfer agent has been named
and served as a defendant in the pending litigation proceedings.  A motion to
dismiss the proceedings against the transfer agent was denied by the federal
district court in this case, and the transfer agent has filed an answer
denying liability.  Based upon information obtained to date, it is Company's
counsel's opinion it is probable the Company has a meritorious cause of action
against the transfer agent.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

      The following discussion should be read in conjunction with the
Consolidated Financial Statements and notes thereto appearing elsewhere in
this Report.

      CERTAIN INFORMATION IN THIS REPORT INCLUDES FORWARD-LOOKING STATEMENTS
WITHIN THE MEANING OF APPLICABLE SECURITIES LAWS THAT INVOLVE SUBSTANTIAL
RISKS AND UNCERTAINTIES INCLUDING, BUT NOT LIMITED TO, THE ABILITY OF THE
COMPANY TO CONTINUE AS A GOING CONCERN AND TO OBTAIN ADDITIONAL CAPITAL, AS TO
WHICH THERE IS NO ASSURANCE, MARKET ACCEPTANCE OF NEW TECHNOLOGIES, ECONOMIC,
COMPETITIVE, GOVERNMENTAL AND TECHNOLOGICAL FACTORS AFFECTING THE COMPANY'S
OPERATIONS, MARKETS, SERVICES AND PRICES, AND OTHER FACTORS DESCRIBED IN THIS
REPORT AND IN PRIOR FILINGS WITH THE SECURITIES AND EXCHANGE COMMISSION.  THE
COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE SUGGESTED OR
IMPLIED BY ANY FORWARD-LOOKING STATEMENTS AS A RESULT OF SUCH RISKS.

INTRODUCTION, GOING CONCERN AND PLAN OF OPERATION     

      ACE is a holding company with interests in the laser vision correction
(LVC) centers business through its wholly owned subsidiary, ICON Vision
Centers, Inc. (Ontario, Canada), and through a majority ownership position in
Vista Technologies, Inc. (Nevada).  ACE also has interests in the LVC
distribution business through Windsor LASIK Products Corp. and in the
outsourcing of collision work for insurance companies through First American
AMO.

      ACE's business plan is to expand its interests in the ownership and
operation of laser vision correction facilities and services, and to acquire
equity interests in, and arrange financing for, new business ventures. 
Pursuant to this strategy: (1) in May 1997, ACE formed First American AMO,
based in Florida, to provide insurance companies with access to a network of
third-party preferred providers for automobile repairs and emergency road
service; and (2) in August 1997, ACE organized ICON Vision Centers, Inc. 
("ICON") in Ontario, Canada to negotiate the acquisition of interests in
additional laser vision correction facilities.  ICON Vision Centers, Inc. is
currently developing a business plan which, if implemented, would cause ICON
Vision Centers to develop opportunities in North America and/or Europe through
acquisitions or start-up development.

     As of February 28, 1997 ACE has an accumulated deficit of $18,692,005,
total assets of $8,118,894 and total shareholders' equity of $306,293.  ACE's
majority owned subsidiary , Vista has an accumulated deficit of $22,142,284,
total assets of $4,330,537, total shareholders deficiency of $2,094,820 and
received a Going Concern opinion from its auditors for the twelve months ended
March 31, 1997 (see Vista's March 31, 1997 10K for additional information). 
ACE, including Vista, has not yet achieved profitable operations and there is
no assurance that profitable operations, if achieved, could be sustained on a
continuing basis.  Further, the Company's future operations are dependent on
the success of the commercialization efforts and market acceptability of the
ACE business plan and other potential business ventures of the Company,
together with the value derived from TCPI investment securities. 

      The Company has experienced significant net losses, a loss from
continuing operations of approximately $10,316,000, has a working capital
deficit of approximately $874,000 and utilized approximately $4,173,000 in
cash for operating activities for the year ended February 28,1997.  In
addition, the Company has serious liquidity problems primarily due to
unsuccessful attempts by Vista to raise money, both at the parent level and
the subsidiary level and significant costs associated with Vista's failed
attempts to penetrate the North American vision correction market resulting in
losses from operations.

                                   -29-
<PAGE>
      AS A RESULT OF THE ABOVE FACTORS, THE REPORT OF MOORE STEPHENS, P.C. ON
THE FINANCIAL STATEMENTS OF THE COMPANY FOR THE FISCAL YEAR ENDED FEBRUARY 28,
1997 CONTAINS A PARAGRAPH EXPRESSING SUBSTANTIAL DOUBT CONCERNING THE ABILITY
OF THE COMPANY TO CONTINUE AS A GOING CONCERN.   Management's plans to address
these matters are as follows:  The Company and its subsidiaries are developing
business plans which when implemented would develop opportunities in the laser
vision correction and automotive maintenance markets in North America and/or
Europe.  Vista's management is developing a business plan which takes
advantage of new trends in the laser vision correction business in both North
America and Europe.  Vista plans to concentrate on its four successful centers
in Italy and Sweden in the 1997-1998 fiscal year and focus on the reduction of
expenses at the head office level.  The Company also plans to sell a portion
of its marketable securities, obtain additional debt financing and focus on
revenue growth of its existing operations.

      The financial statements do not include any adjustments that might be
necessary if the Company is unable to continue as a going concern.  The
continuation of the Company as a going concern is dependent upon the success
of these plans.  There can be no assurance of the success of these plans.

     Prior to fiscal 1997 the Company was mainly involved in the research and
development of transdermal drug delivery systems and skin permeation
technology.  The Company developed and patented proprietary technology and
secured licensing and product feasibility agreements through research in this
area.

     On November 15, 1995, Pharma Patch sold substantially all of the
operating assets of the Company to Technical Chemicals and Products, Inc.
(TCPI) for a gain of approximately $16.4 million.
     
     On March 21, 1996, the Company completed the acquisition of 61.3% of the
voting interest of Vista Technologies Inc.

     ACE's current operational expenses are being funded by the sale of a
portion of the TCPI stock acquired in the November 15, 1995 transaction. 
Although ACE is primarily involved with LVC facilities and services, through
its subsidiary Vista, management of ACE is also actively involved in
investigating and negotiating other business opportunities to increase
shareholder value.
     
     Vista commenced business operations in February 1994.  Vista acquired
controlling equity interests in European subsidiaries during 1994,made
substantial investments in Medical Development Resources, Inc. ('MDRI")and its
subsidiaries in 1994 and 1995, developed a strategic plan in mid-1995 to
sponsor and invest in Regional Joint Ventures to conduct additional businesses
engaged in providing access to laser vision correction ("LVC") equipment and
related services ("LVC Services") in regional markets of North America, and
Vista acquired a controlling interest during 1996 in Vista Laser Centers of
the Southwest, Inc. ("Vista-Southwest"), an operating company based in
Arizona.

      Since commencing operations, Vista has financed its business operations,
acquisition and expansion activities primarily from the issuance or sale of
equity securities, debt financing and loans from its controlling stockholder,
ACE.  From February 1994 through March 31, 1996, the Company had received
approximately $7,437,500 from the sale of common stock and warrants,
approximately $278,000 from the sale of convertible debt instruments, and had
issued additional common stock and warrants in connection with the acquisition
of other assets and investments.  During the fiscal year ended March 31, 1997,
Vista received an additional $1,050,100 from the sale of common stock and
exercise of stock options and warrants, approximately $1,523,000 as loans from
ACE and its corporate predecessor (of which $800,000 has been repaid),
$300,000 from the sale of secured debt, and issued additional shares of common
stock and warrants in connection with the acquisition of other assets and
investments.

                                   -30-
<PAGE>
      Vista made significant investments in MDRI and its subsidiaries from May
1994 through March 1995 and in certain Regional Joint Ventures during 1995 and
1996 for which business acquisition and related third-party financing
negotiations have been abandoned.  Vista's investment in cash, securities
issued and loans advanced for its investment in MDRI of approximately
$5,643,000 was written-off at March 31, 1995 and additional investments in
cash, securities issued and loans advanced to Regional Joint Ventures of
approximately $1,934,000 were written-off primarily during the fiscal year
ended March 31, 1997.

      At March 31, 1997, Vista had an accumulated deficit of $22,142,000
incurred largely as a result of write-offs during fiscal 1995 through fiscal
1997 and losses from operations since 1994.  Vista's net losses for the fiscal
year ended March 31, 1997 was $6,999,000.  At March 31, 1997, Vista had a
negative working capital of $3,119,000 and a stockholders' deficiency of
$2,095,000.  Vista has serious liquidity problems primarily due to
unsuccessful attempts to raise additional capital and significant costs
associated with failed attempts to penetrate North American laser vision
correction markets.

      As a result of the above factors, the report of Moore Stephens, P.C. on
the financial statements of Vista for the fiscal year ended March 31, 1997
contains a paragraph expressing substantial doubt concerning the ability of
Vista to continue as a going concern.

      Management's plans to address these matters are as follows:  The Company
and its subsidiaries are developing business plans which when implemented
would develop opportunities in the laser vision correction and automotive
maintenance markets in North America and/or Europe.  Vista's management is
developing a business plan which takes advantage of new trends in the laser
vision correction business in both North America and Europe.  Vista plans to
concentrate on its four successful centers in Italy and Sweden in the 1997-
1998 fiscal year and focus on the reduction of expenses at the head office
level.  The Company also plans to sell a portion of its marketable securities,
obtain additional debt financing and focus on revenue growth of its existing
operations.  The accompanying financial statements do not reflect any
adjustments to the carrying value or classifications of assets or liabilities
which might become necessary if Vista is unable to continue as a going
concern.  The continuation of Vista as a going concern is dependent upon the
success of these plans.  There can be no assurance that Vista will be
successful in implementing these plans.

      Management is currently developing a business plan which will be
evaluated and implemented subject to an analysis intended to take advantage of
new trends in the laser vision correction market in both North America and
Europe.  Because of Vista's limited ability to raise capital in this new
industry due to its historical results and the unprofitable nature of the
industry itself, Vista plans to take a conservative approach and hopes to
build mainly on its successful European base of centers in Italy and Sweden. 
Efforts by Vista's former management in late 1996 to obtain additional equity
capital were non-productive, no negotiations are currently in process to
obtain additional capital and Vista has been dependent in recent periods upon
advances from its controlling stockholder, ACE, for funds to maintain
operations.  Outstanding advances due to ACE are classified as short-term
obligations, totalled $723,000 as of March 31, 1997, and have subsequently
increased to approximately $1,100,000 as of November 6, 1997.  There can be no
assurance that ACE will continue to provide advances to the Company or that
Vista will be successful in obtaining capital from other sources.

      Vista's business activities are subject to both predictable and
unforeseen risks incident to the creation of new businesses with a limited
history of operations.  Prospective investors should consider Vista's current
financial condition, its history of losses from operations, the frequency with
which newly developed businesses encounter unforeseen expenses, difficulties,
complications and delays, and other factors such as the competitive industry
in which Vista operates.

RESULTS OF OPERATIONS:

FISCAL YEAR ENDED FEBRUARY 28, 1997 COMPARED TO YEAR ENDED FEBRUARY 29, 1996

      The consolidated financial statements include the accounts of ACE and
its wholly and majority owned subsidiaries in Canada and in the United States.
All significant intercompany balances and transactions have been eliminated in
consolidation. The Company has consolidated its results for the year ended
February 28, 1997 with the results of operations of Vista for the year ended
March 31, 1997 in accordance with U.S. GAAP.  Results of operations vary
significantly between February 29, 1996 and February 28, 1997 because Vista's
operations were not consolidated with Ace's at February 29, 1996 as the
controlling interest in Vista was not acquired until March 21, 1996.

      REVENUES:   During the fiscal year ended February 28, 1997 (the "1997
Year"), consolidated revenues from operations were $3,486,000, compared to 
$0 in consolidated revenues for the fiscal year ended February 28, 1996 (the
"1996 Year"). Consolidated revenues in the 1997 Year principally included
$1,486,000 attributable to the operations of Vista-Italy, $1,712,000 from the
operations of Vista-Sweden, and $259,000 in revenues at Vista-Southwest
acquired during the 1997 Year. This increase in revenue is a result of ACE
acquiring the controlling interest in Vista in March of 1996.  Consolidated
revenues from the 1996 year are included in Loss from Discontinued Operations
and primarily related to feasibility studies conducted by ACE on behalf of
third parties.  ACE does not have similar income in the 1997 year. 

     For the 1996 Year, Vista's consolidated operating results included the
period from January 1995 through December 1995 for its European subsidiaries
to eliminate a three month delay in obtaining European financial statements. 
A decision was made by Vista's management in 1996 to bring the operating
reporting periods for its European subsidiaries current with the parent
corporation.  This resulted in a change in reporting periods for European
subsidiaries included in the consolidated financial statements so that their
twelve month period from April 1996 through March 1997, included in the 1997
Year, is being compared to European operations for the twelve month period
from January through December 1995 included in Vista's consolidated results
for the 1996 Year.  The extra quarter's net results of European operations
from January through March 1996 is accounted for in ACE's consolidated
financial statements at February 28, 1997 as an adjustment to equity.

      OPERATING EXPENSES:   Costs and expenses of operations for the 1997 Year
were $13,801,000, an increase of $12,000,100 compared to costs and expenses of
operations of $1,801,000 in the 1996 Year.  Costs and expenses in the 1997
Year consisted of $8,664,000 in general and administrative expenses, a 382%
increase compared to the 1996 Year of $1,799,000, $4,280,000 in  Goodwill
associated with the acquisition of Vista was written off, $777,000 in
depreciation and amortization compared to the 1996 year of $0, and 276,000 in
interest expense compared to the 1996 year of $0.  Both Depreciation and
interest expense were included in Loss from discontinued operations for 1996. 
General and administrative expenses for the 1997 Year included $3,308,000 for
Vista Corporate Office, $2,058,000 for Ace Corporate Office, $1,300,000 for
Vista-Italy, $1,445,000 for Vista-Sweden, and $553,000 for Vista-Southwest
acquired during the 1997 Year. General and administrative expenses at the ACE
parent Company level included audit, legal, and consulting expenses of
$945,000, printing fees of $673,000 and office costs and salaries of $166,000. 
General and administrative expenses at the Vista Head Office level included
the write-off by Vista of $1,934,000 in investments and advances to Regional
Joint Ventures, marketing, audit, legal and consulting expenses of $1,200,000,
salary expenses of $669,000 and travel expenses of $371,000 incurred primarily
as a result of activities relating to negotiations for development of Regional
Joint Ventures.   

                                   -32-
<PAGE>
      Vista's European subsidiaries realized nominal income from operations
during the year. Cash flow from operations in the 1997 Year were approximately
cash neutral at both Vista-Italy and Vista-Sweden and negative at
Vista-Southwest.  Profitable operations from operating subsidiaries in the
future will be dependent upon increasing revenues, as to which there can be no
assurance. 

      Since March 1997, corporate expenses for salaries, marketing, travel and
legal expenses at the Vista Corporate Office level have been reduced to
approximately $60,000 per month for the quarter ended June 30, 1997, primarily
due to a reduction in staff, termination of negotiations relating to the
proposed acquisition of other LVC entities and abandonment of unsuccessful
private placement financing activities sought by prior management. 

       OTHER NON-OPERATING EXPENSE AND INCOME:  Other non-operating expense
and income totaled a net expense of $2,323,000 for the 1997 Year compared to a
net other income of $72,000 for the 1996 year.  The primary portions of the
1997 net expense included a realized loss of $2,096,000 on the sale of
securities, most of which was attributable to a decline in market price for
ACE's investment in TCPI common stock.  In addition, 1997 included total
operating interest expense of $304,000 in 1997 while $338,000 in interest
expense was included in Loss from discontinued operations for the 1996 year.

     DISCONTINUED OPERATIONS:  ACE has no income or expenses from discontinued
operations in the 1997 year compared to a net gain on discontinued operations
of $13,819,000 In 1996.  The 1996 gain was a result of the November 1995 TCPI
transaction.  The operations of the Company's Subsidiaries involved in the
transaction are being classified as discontinued operations in accordance with
US GAAP.

     NET LOSS:  Net loss for the 1997 Year was $12,546,000, equal to a net
loss of $7.54 per common share, compared to a net income in the 1996 Year of
$12,091,000, or $15.05 per common share.  The primary portion of such a
decrease is due to the Gain on sale of business segment in the 1996 year and
Ace's new investment in Vista for the 1997 year.

INCOME TAXES
 
      Deferred income taxes reflect the net tax effects of (a) temporary
differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes, and
(b) operating loss and tax credit carryforwards.  ACE had research and
development expenses not claimed for income tax purposes of approximately
$2,870,000, available to reduce taxable income of ACE in future years. Due to
the significant uncertainty relating to the Company's ability to utilize these
expenses to offset taxable income, valuation allowances are recognized to
offset all of the deferred tax assets relating to these expenses. These
unclaimed research and development expenses may be carried forward
indefinitely for income tax purposes.  

      Vista has net operating losses carryforwards totaling approximately
$8,200,000, which expire between the years 2007 and 2012.  As of February 28,
1997, ACE may not have available the Vista NOL's to offset against future ACE
taxable income, however, Vista's NOL are available against future Vista
income. Vista's use of these carryforwards may be limited by Section 382 of
the Internal Revenue Code. 

      ACE is not required to file a US consolidated income tax return. 
Accordingly, the net operating loss carryforwards of Pharma Patch may not be
available to reduced future taxable income as a result of the Company's
reorganization in January of 1997. 


                                   -33-
<PAGE>
LIQUIDITY AND CAPITAL RESOURCES

      ACE principal capital requirements include cash requirements for Ace's
management and administration and to support the activities of Vista Phoenix
location.  Subject to the availability of additional capital, as to which
there can be no assurance, Vista may also incur additional expenditures in the
future for marketing activities and to expand operations by acquiring or
developing additional LVC centers and for additional excimer laser equipment.

     Consolidated cash increased by 1,138,000 to $1,807,000 at February 28,
1997 compared to $669,000 at February 29, 1996.  This increase in consolidated
cash of $1,138,000 from February 29, 1996 to February 28, 1997 represents the
net proceeds from shares issued for cash, the proceeds of debt of $905,000,
and net proceeds from the sale of TCPI Stock totaling $5,511,000.  These
sources of cash were offset by cash requirements of operations of $4,173,000,
the purchase of fixed assets for $727,000, advances to investee companies of
$802,000, the issuance of notes receivable of $411,000 and the repayment of
$339,000 of capital lease obligations.

      Between March 1, 1997 and December 31, 1997, ACE sold 175,000 TCPI
shares for net proceeds of approximately $1,676,000.  This resulted in a net
loss of approximately $1,000,000.  The proceeds were utilized for operations
and to purchase additional investments through December 31, 1997.  As of
February 28, 1998, ACE had 43,850 shares of TCPI.
 
     Vista's European operating subsidiaries have achieved at least neutral
cash flow levels of operations for the last two fiscal years.  Vista plans to
satisfy its cash needs over the next 12 months by decreasing Vista's expenses
and cash requirements, proposing a debt compromise plan with Vista's
creditors, continuing in the interim to defer payments to Vista's creditors or
possibly converting debt to equity, increasing its revenues at its existing
vision correction centers, selling assets, raising additional capital and/or
incurring additional borrowings.  Consolidated revenues for the three month
period ended June 30, 1997 of approximately $1,230,000 (unaudited) reflect an
increase of 56% over the prior year equivalent period. This revenue increase
was attributable to acquisition of Vista's operating subsidiary in Scottsdale,
Arizona ($303,000) and volume increases in Europe ($141,000).  For the three
months ended June 30, 1997, total laser vision correction procedures for Vista
were 1,324 versus 695 for the three months ended June 30,1996, reflecting an
increase of 90% in procedures.  The consolidated net loss for the three months
ended June 30, 1997 was approximately $250,000 versus a net loss of
approximately $804,000 for the three months ended June 30, 1996. The reduction
in net loss is primarily due to the revenue increases described above and a
reduction in corporate general and administrative expenses.  The loss of
approximately $250,000 for the three months ended June 30, 1997 includes a net
loss of approximately $60,000 from Vista's operations in Sweden primarily due
to the opening of a new center and due to a $173,000 loss on sale of TCPI
shares.  Therefore, continued revenue increases will be dependent, among other
things, in part upon expanding use of Vista's services by physicians, general
public acceptance of laser surgery to correct refractive disorders, and
competitive factors.  For the quarter ended September 30, 1997, revenues were
reduced compared to the quarter ended June 30, 1997 as a result of the normal
seasonal closing of operations during a holiday month in Europe.  There can be
no assurance that Vista will be successful in implementing these plans.

     ACE's management is focusing its attention at present on increasing
Vista's revenues and reducing negative cash flows as well as exploring other
financing and business opportunities.  ACE has been dependant on its
investments in marketable securities to sustain its operations.  Vista has
been dependent in recent periods upon advances from its controlling
stockholder, ACE, for funds to sustain Vista's operations. Outstanding
advances due to ACE are classified as short-term obligations, totaled $723,000
as of March 31, 1997, and have subsequently increased to approximately
$1,100,000 as of September 30, 1997.  The advances from ACE are secured by

                                   -34-
<PAGE>
Vista's agreement to pledge shares of its European subsidiaries as collateral
security and all of Vista's assets are subject to a security interest granted
to the holder of a note in the principal amount of $300,000 due on June 30,
1997.  Vista is currently negotiating an amendment to its secured loan of
$300,000 with the note holder.  

      There can be no assurance that ACE will continue to provide advances to
Vista or that Vista will be able to obtain additional capital from other
sources.  Accordingly, there can be no assurance that Vista will have cash
resources necessary to sustain its operations in the United States for any
specific period of time. Additional financing, if any, may result in
significant dilution to existing Vista stockholders.  If adequate funds are
not available from ACE and/or  other third parties and if creditors refuse to
agree to future debt compromise plans, then Vista may be required to accept
unfavorable alternatives, including (i) seeking protection from creditors at
the parent company level under the bankruptcy laws, (ii) arrangements with
collaborative partners that may require Vista to relinquish material interests
in its operating subsidiaries that it would not otherwise relinquish, or (iii)
the delay, reduction or elimination of its planned expansion, capital
expenditures, marketing and advertising and other operating expenses.

      During fiscal 1997, the Company completed a private placement and issued
60,000 shares for cash consideration of $300,000 and also issued 63,874 shares
in lieu of cash payments of $323,236 to various professionals for services
rendered.  On March 21,1996, the Company issued 450,000 shares to three
investors as consideration for 900,000 shares of Vista.

      Through its agreement with First American AMO, ACE has agreed to fund
AMO up to $450,000 prior to any separate outside funding of AMO.  Between
March 1, 1997 and February 28, 1998, ACE has advanced AMO a total of $310,000. 
AMO is planning its expansion and, with the assistance of ACE, is preparing
for the need of new outside financing.  There can be no assurance that ACE
will successfully obtain financing from third parties for this venture.

exchange up to 32,023 shares of common stock in ACE at a rate of one ACE share
for each 100 Class A, B. C and/or D Warrants.  The exchange offered expired on
May 30, 1997 and as a result 15,230 shares of ACE were issued to holders of
Pharma Patch Warrants.
     
  OTHER EVENTS

  Management of Atlantic Central Enterprises Limited (the "Company")
discovered for the first time on December 12, 1997 that its former U.S.
counsel, Kevin J. Quinn of Santa Monica, California, fraudulently caused
960,000 newly issued and freely-tradable shares of the Company's common stock
to be issued to Mr. Quinn, his affiliate or to his brokerage account in
Vancouver, Canada, during the period from March 25, 1997 through July 31,
1997.  This information was discovered by the Company in the course of
assembling data from the Company's transfer agent for the Company's audited
financial statements.  As a result, records of the transfer agent indicate
there are currently 2,662,396 shares outstanding of the Company's common stock
including the 960,000 shares issued without consideration at Mr. Quinn's
fraudulent instructions and without the prior authorization or knowledge of
the Company's Board of Directors and management.

  This discovery follows the termination in 1997 of Mr. Quinn's
relationship with the Company.  Mr. Quinn acted as U.S. corporate and
securities counsel to the Company and its predecessor, Pharma Patch plc, from
1993 until approximately June 1997.  The Company learned of an article in the
November 1997 issue of the California Bar Journal reporting that Kevin J.
Quinn had been suspended from the practice of law in 1993 as a result of a
1992 felony conviction which was recently reduced to a misdemeanor for
embezzlement and that he was permanently disbarred by the California State Bar
in September 1997.  Those facts had not been previously disclosed to any
officers or directors of Pharma Patch plc from the time of its inception in
1993 or to the management of Atlantic Central since its inception in 1996.

  When confronted with these disclosures, recent correspondence from Mr.
Quinn to the Company's new counsel does not deny his 1992 conviction, his 1993
suspension from the practice of law or that he was disbarred in September
1997.  The Company notes that notwithstanding his suspension from the practice
of law since 1993, Mr. Quinn continued through 1997 to be listed as a
practicing attorney in California by the Martindale-Hubbell Law Directory.

  The Vancouver brokerage firm that is reported to have received all or
most of the fraudulently issued shares advised the Company on Friday December
12, 1997 that it currently has no position in the Company's securities.  The
Company's transfer agent likewise has confirmed that none of the original
registered owners of the Company's common stock are currently listed as record
owners of the Company's common stock.  This information leads the Company to
believe, at present, that the fraudulently issued securities all were sold for
Mr. Quinn's account, and the Company is continuing its investigation.

                                   -37-
<PAGE>
  The Company has demanded full restitution from Mr. Quinn of all legal
fees and expenses previously paid for Mr. Quinn's account and a restitution or
damages for the fraudulently issues shares.  Commencing in December 1997, ACE
instituted litigation proceedings entitled Atlantic Central Enterprises
Limited vs. Kevin J. Quinn, et al in the United States District Court for the
Central District of California, Case No. 97-9420AAH (ANX), and in the Supreme
Court of British Columbia, Vancouver Registry No. C980037 (collectively the
"Quinn Litigation Proceedings").  In the Quinn Litigation Proceedings, the
Company seeks a judgement for compensatory damages in the amount of
approximately $750,000 in legal fees and costs paid by the Company to Mr.
Quinn during the period from 1993 to 1997 while he fraudulently represented
himself to be a licensed attorney, damages for the 960,000 fraudulently issued
shares of the Company's common stock, and other compensatory, punitive and
exemplary damages.  The Company has assigned a value of $400,000 for the
960,000 shares fraudulently issued and will charge operations with the value
calculated using the market value on the dates the shares were issued.  It is
the Company's intention to pursue legal action where it will seek the return
and cancellation of these 960,000 shares or other restitution equivalent to
the value of those shares.  At hearings held in December 1997 and January
1998, orders of preliminary injunction were issued restraining the transfer of
assets from accounts with any financial institutions maintained by Mr. Quinn
and certain corporate entities controlled by Mr. Quinn.  Pursuant to those
orders, approximately $220,000 of cash and securities in accounts maintained
by Mr. Quinn have been frozen.  Mr. Quinn has filed responsive pleadings in
the Quinn Litigation Proceedings denying liability.  Counsel for the Company,
based upon an ongoing investigation of documents and other information, has
expressed the opinion that the Company has meritorious causes of action
against Mr. Quinn.  The ability of the Company to realize on any such
judgements, if successfully obtained, will be dependent upon the Company's
ability to locate and levy upon assets of Mr. Quinn.

  The Company is also investigating potential claims against other third
parties that may have aided and abetted Mr. Quinn with respect to the one or
more of the causes of action asserted by the Company in the Quinn Litigation
Proceedings.  In addition to Mr. Quinn and two entities believed to be under
his control, the Company's transfer agent has been named and served as a
defendant in the Quinn Litigation Proceedings.    A motion to dismiss the
proceedings against the transfer agent was denied by the federal district
court in this case, and the transfer agent has filed an answer denying
liability.  Based upon information obtained to date, it is Company's counsel's
opinion it is probable the Company has a meritorious cause of action against
the transfer agent.

OFFSHORE SALES OF COMMON STOCK UNDER REGULATION S

  During February 1996, Vista and ACE negotiated agreements for Vista to
obtain debt and equity financing from ACE's predecessor, Pharma Patch.  In
connection with ACE's acquisition of a controlling interest in Vista, ACE in
March 1996 also acquired 900,000 shares of Vista common stock from third
parties in a transaction exempt from the registration requirements of the
United States securities laws for offshore transactions under Regulation S
promulgated under the Securities Act of 1993 ("Regulation S").  Three Vista
stockholders, including Therapeutic Patch Research N.V. (TPR"), Saliva
Research Limited ("SRL") and Westcliff Partners Inc. ("WPI"), exchanged a
total of 900,000 shares of Vista's outstanding common stock for a total of
450,000 newly issued securities of Pharma Patch in this privately - negotiated
transaction.  No fees or commissions to third parties were paid in connection
with this exchange of securities.  The Vista securities included in this
exchange had been acquired by TPR, SRL and WPI in December 1995 as a result of
prior transactions financing the operations of Vista through December 1995. 
The Company has been advised that TPR, SRL and WPI are clients of Jac J. Lam,
a former director and chief executive officer of Vista.

  From March 1996 to May 1996, ACE offered and sold 189,600 shares of its
common stock to 11 investors in an offshore private placement offering exempt


                                   -38-
<PAGE>
from registration under Regulation S of the United States securities laws. 
For each ACE share issued in this offering, investors paid a purchase price of
$5.00 per share in cash and surrendered 10 Pharma Patch Class C warrants for
cancellation.  The Company received $948,000 in gross proceeds and cancelled
1,896,000 Pharma Patch Class C warrants (the number of warrants is stated
before giving effect to a subsequent 1-for-10 exchange of Pharma Patch shares
for ACE shares in their January 1997 reorganization) from the sale of 189,600
shares of the Company's common stock in the offshore private placement under
Regulation S.  The Company incurred fees payable to a placement agent,
Multibreen B.V., in the aggregate amount of $94,800, resulting in net proceeds
to the Company of $853,200 for the shares sold in the Regulation S offering.

OTHER PRIVATE PLACEMENT OF COMMON STOCK

  From March 1996 to May 1996, ACE offered and sold 25,400 shares of its
common stock to five investors in a private placement offering, primarily to
United States investors, exempt from registration under the U.S. Securities of
1933 for transactions not involving public offering.  For each ACE share
issued in this offering, investors paid a purchase price $5.00 per share in
cash and surrendered 10 Pharma Patch Class C warrants for cancellation.  The
Company received $127,000 in gross proceeds and cancelled 254,000 Pharma Patch
Class C warrants (the number of warrants is stated before giving effect to a
subsequent 1-for-10 exchange of Pharma Patch shares for ACE shares in their
January 1997 reorganization) from the sale of 25,400 shares of the Company's
common stock in this private placement.  The Company incurred fees payable to
a placement agent, Multibreen B.V., in the aggregate amount of $25,400,
resulting in net proceeds to the Company of $101,600 for the shares sold in
this offering.

OTHER SUBSEQUENT EVENTS

  PROMISSORY NOTE - Vista has been negotiating with the holder of a 12%
promissory note for $300,000 who has verbally agreed to extend the maturity
date of the 12% promissory note. Definitive agreements for the 12% promissory
note extension are being prepared and management anticipates that they will be
executed by April 30, 1998.

  SALE OF MARKETABLE SECURITIES - Between March 1, 1997 and July 3, 1997,
the Company sold 35,000 shares of TCPI common stock with net proceeds to the
Company of approximately $360,000. Between July 4, 1997 and December 31, 1997,
the Company sold an additional 180,050 shares of TCPI common stock with net
proceeds to the Company of approximately $1,316,000.  Proceeds were utilized
for operations and to purchase additional investments through December 31,
1997.  The sale of TCPI stock subsequent to March 1, 1997 resulted in a net
loss of approximately $1,000,000 for the Company.  As of February 28, 1998,
the Company had 43,850 shares of TCPI.

  FIRST AMERICAN AMO - In May 1997, Ace entered into an agreement to form
a new corporation, First American AMO ["AMO"], which is located in Palm
Harbor, Florida.  Ace agreed to fund AMO up to $450,000 prior to separate
outside funding of AMO.  Ace owns 83% of the issued and outstanding common
stock of AMO upon signing of this agreement.  AMO is an automotive maintenance
organization that improves the efficiencies of fixing a car.  

  ASSET PURCHASE AGREEMENTS - In July 1997, Vista Southwest entered into
an asset purchase and lease assumption agreement whereby Vista Southwest
agreed to purchase certain equipment for a total purchase price of $411,860,
consisting of $50,000 in cash payments, $361,860 in a promissory note with
annual interest of 8%.  The principal and interest on the note is due the
earlier of June 30, 1999 or 30 days following the close of an offering of
securities of Vista Southwest or Vista Technologies, Inc. with net proceeds of
not less than $2,000,000.  The estimated fair value of the acquired equipment
is $120,000.  Therefore, goodwill of approximately $292,000 was recorded on
this transaction.

                                   -39-
<PAGE>
  Also in July 1997, ICON Vision Centers, Inc., a wholly owned subsidiary
of the Company, entered into an asset purchase agreement to purchase certain
fixed assets and inventory for a total purchase price of $128,000, consisting
of $25,600 in cash and $102,400 in a non-interest bearing promissory note. 
The note has monthly payments of $3,200 and will be paid in full by April 30,
2000.  The estimated fair value of the inventory and fixed assets is
approximately $50,000.  Therefore, goodwill of approximately $78,000 was
recorded on this transaction.

  ADDITIONAL DEBT FINANCING -  Subsequent to year end, ACE opened a margin
account with its broker and borrowed funds against its holdings of TCPI
shares.  At February 28, 1998, there was no balance owing on the margin
account.

AUTHORITATIVE PRONOUNCEMENTS

      The Financial Accounting Standards Board ("FASB") has issued Statement
of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share", and
SFAS No. 129, "Disclosure of Information About Capital Structure".  Both are
effective for financial statements issued for periods ending after December
15, 1997.  SFAS No. 128 simplifies the computation of earnings per share by
replacing the presentation of primary earnings per share with a presentation
of basic earnings per share.  The statement requires dual presentation of
basic and diluted earnings per share by entities with complex capital
structures.  Basic earnings per share include no dilution and is computed by
dividing income available to common stockholders by the weighted average
number of shares outstanding for the period.  Diluted earnings per share
reflect the potential dilution of securities that could share in the earnings
of an entity similar to fully diluted earnings per share.

      While Vista has not analyzed SFAS No. 128 sufficiently to determine its
long-term impact on per share reported amounts, SFAS No. 128 should not have a
significant effect on historically reported per share loss amounts.

      SFAS No. 129 does not change any previous disclosure requirements, but
rather consolidates existing disclosure requirements for ease of retrieval.

      The FASB has issued SFAS No. 130, "Reporting Comprehensive Income". SFAS
No. 130 is effective for fiscal years beginning after December 15, 1997.
Earlier application is permitted.  Reclassification of financial statements
for earlier periods provided for comparative purposes is required.  SFAS
No.130 is not expected to have a material impact on Vista.

      The FASB has issued FASB No. 131, "Disclosures About Segments of an
Enterprise and Related Information".  SFAS No. 131 changes how operating
segments are reported in annual financial statements and requires the
reporting of selected information about operating segments in interim
financial reports issued to stockholders.  SFAS No. 131 is effective for
periods beginning after December 15, 1997, and comparative information for
earlier years is to be restated.  SFAS No. 131 need not be applied to interim
financial statements in the initial year of its application.  SFAS No. 131 is
not expected to have a material impact on Vista.

U.S. DOLLAR PRESENTATION AND FOREIGN CURRENCY FLUCTUATIONS

     Except as otherwise stated in this Report, all monetary amounts have been
presented in U.S. dollars.

      Vista's European operating subsidiaries in Italy and Sweden currently
represent a significant portion of Vista's revenues and expenses that are
collected and paid in foreign currencies.  Vista publishes its consolidated
financial statements in U.S. dollars after translating transactions in foreign
currencies into U.S. dollars.  In periods when the U.S. dollar depreciates

                                   -40-
<PAGE>
against the relevant foreign currencies, reported earnings attributable to
transactions in foreign currencies may be materially enhanced.  In periods
when the U.S. dollar appreciates against the relevant foreign currencies,
however, reported earnings attributable to transactions in foreign currencies
may be materially reduced.  Fluctuations in the exchange rate between foreign
currencies and the U.S. dollar may also affect the book value of Vista's
assets and the amount of its stockholders' equity.

ITEM 8. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE

  As reported in ACE's Current Report on From 8-K dated May 28,1997, ACE
changed its independent accountants in May 1997.  The accounting firm of KPMG
Peat Marwick LLP acted as principal independent public accountants to audit
the consolidated financial statements of ACE for its fiscal year ended
February 29, 1996.  On May 28, 1997, the Company was advised by KPMG Peat
Marwick LLP that the client-auditor relationship between ACE and KPMG Peat
Marwick LLP had been terminated.  The report of KPMG Peat Marwick LLP on the
consolidated financial statements of ACE for the fiscal year ended February
29, 1996 did not contain an adverse opinion or a disclaimer of opinion, and
was not qualified is to uncertainty, audit scope, or accounting principles. 
The decision to terminate the client-auditor relationship between ACE and KPMG
Peat Marwick LLP was initiated by KPMG Peat Marwick LLP, and ACE's Board of
Directors accordingly did not participate in a decision to change the
Company's independent accountants.  In connection with its audit for the
fiscal year ended February 29, 1996 and the subsequent interim period through

                                   -41-
<PAGE>
May 28, 1997, there were no disagreements of ACE with KPMG Peat Marwick LLP on
any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements if not
resolved to the satisfaction of  KPMG Peat Marwick LLP would have caused them
to make reference thereto in their report on the financial statements for such
year.  During the fiscal year ended February 29, 1996 and prior fiscal periods
of ACE, there have been no reportable events (as defined in Regulation S-K
Item 304(a)(1)(v)).

  On May 30, 1997, ACE engaged the services of the independent public
accounting firm of Moore Stephens, P.C. to act as the principal independent
accountants as to ACE's consolidated financial statements for its most recent
fiscal year ended February 28, 1997.   Prior to engaging Moore Stephens, P.C.,
ACE did not consult its new independent public accountants as to the
application of accounting principles to a specified transaction, either
completed or proposed, or as to the type of audit opinion that might be
rendered on ACE's financial statements.  ACE's Board of Directors participated
in and approved the decision to appoint Moore Stephens, P.C. to act as the
principal independent accountants as to the Company's consolidated financial
statements for its most recent fiscal year ended February 28, 1997.

MANAGEMENT OF THE COMPANY
   
     There is no family relationship between any of ACE's directors and
executive officers.  All directors hold office until the next annual meeting
of stockholders and until their successors are elected.  Officers serve at the
discretion of the Board of Directors.  There are no arrangements or
understandings between any director and any other person pursuant to which any
person was elected or nominated as a director.

      The Board of Directors currently has no committees of the Board.

      During the fiscal year ended February 28, 1997 the Board of Directors
held eight meetings and took certain actions by unanimous written consent of
the  Board.  No director attended fewer than 75% of all meetings of the Board
of Directors.

                                   -44-
<PAGE>
COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

      Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange
Act") requires ACE's executive officers and directors, and persons who
beneficially own more than 10% of ACE's stock, to file initial reports of
ownership and reports of changes in ownership with the Securities and Exchange
Commission.  Based upon a review of the copies of such forms furnished to ACE,
responses from ACE's executive officers and directors in reply to monthly
questionnaires, and other information available to ACE, ACE believes that as
of February 28, 1997, all Section 16(a) filing requirements applicable to its
executive officers and directors were complied with.

      Certain foreign corporate shareholders hold ACE common stock and
warrants and are believed in certain cases to share common management.  Inmost
instances, beneficial ownership of ACE securities held by such foreign
corporate shareholders has not been disclosed to ACE.  Based on information
available to ACE, ACE has no reason to believe that any of such parties are
currently required to file reports under Section 16(a) of the Exchange Act. 
However, since ACE does not necessarily have access to all information that
may be relevant, ACE expresses no opinion whether any such group of foreign
investors that may share common management may be required to file reports
under Section 16(a) of the Exchange Act.

THE 1996 STOCK OPTION PLAN

       On February 2, 1996, the Company's Board of Directors proposed the 1996
Stock Option Plan [Option Plan} that was approved by the stockholders of the
Company in 1996.  The purpose of the Option Plan is to permit the Board or a
Committee of the Board the flexibility of granting options of the Company's
common stock in lieu of cash to compensate officers, directors, employees and
other individuals acting as professionals, consultants and/or advisers to the
Company for services rendered to the Company and its subsidiaries.  A total of
350,000 shares of common stock are available for payment of compensation under
the Option Plan.  No compensation awards under the Option Plan have been made.

OTHER

      ACE currently has no pension, retirement, annuity, savings or similar
benefit plan which provides compensation to its executive officers or
directors except for group health and life insurance plans.

ITEM 12.      CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Atlantic Central Enterprises Limited ("ACE") is a Bermuda company with
securities publicly traded in the United States over-the-counter market.  In
January 1997, ACE acquired all of the assets and liabilities of Pharma Patch
Plc ("Pharma Patch"), a publicly-traded company with its principal office in
Dublin, Ireland.  Pharma Patch Plc was an Irish public company formerly
engaged in research and development of advanced transdermal drug delivery
systems and advanced skin penetration enhancers, a business sold by Pharma
Patch in late 1995 to Technical Chemical Products, Inc.  References in this
Report to Atlantic Central as to periods prior to February 1997 include Pharma
Patch as the predecessor-in-interest of Atlantic Central.

      As described in more detail below, Atlantic Central acquired a
controlling equity interest in Vista in March 1996 and owned 3,423,800 shares
of Vista's common stock at August 31, 1997, representing approximately 54.1%of
Vista outstanding Vista common stock.  Since February 1996, Atlantic Central
has charged Vista for allocations of certain salaries and office expenses
incurred by Atlantic Central in Toronto, Canada for use of a portion of
management time devoted to Vista by Murray D. Watson and Kenneth G. Howling
and their support staff.  Atlantic Central has also advanced funds to or for
Vista's account from time to time, of which $800,000 was repaid in cash in
late 1996.

      Vista has been dependent in recent periods upon advances from Atlantic
Central for funds to sustain Vista's operations.  Outstanding advances due to
Atlantic Central are classified as short-term obligations, totaled $723,000 as
of February 28, 1997, and have subsequently increased to approximately
$1,100,000 as of September 30, 1997.  Advances from Atlantic Central are
secured by Vista's agreement to pledge shares of its European subsidiaries as
collateral security for repayment of its obligations to Atlantic Central. 
There can be no assurance that Atlantic Central will continue to provide
advances to Vista or that Vista will be able to obtain additional capital from
other sources.

      Murray D. Watson served from July 1993 to June 5, 1997 as Chairman of
the Board, Chief Executive Officer and a director of ACE and is currently
employed as an executive officer of another subsidiary of ACE.  Mr. Watson has
also served as a director and Vice Chairman of Vista from February 1994 to the
present time, and has served as acting President and Chief Executive Officer
of Vista from March 6, 1997 to July 22, 1997 and from September 9, 1997 to the
present date.  Kenneth G. Howling, former Vice President and Chief Financial
Officer of ACE, served as Vista's Treasurer and Chief Financial Officer from
February 16, 1996 to November 14, 1997.

                       INDEPENDENT AUDITOR'S REPORT


The Board of Directors and Stockholders of
  Atlantic Central Enterprises Limited
  Bermuda


        We have audited the accompanying consolidated balance sheet of
Atlantic Central Enterprises Limited as of February 28, 1997, and the related
consolidated statements of operations, stockholders' equity, and cash flows
for the year ended February 28, 1997.  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 audit in accordance with generally accepted
auditing standards.  Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the consolidated financial
statements are free of material misstatement.  An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated financial statements.  An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall consolidated financial statement presentation. 
We believe that our audit provides a reasonable basis for our opinion.

        In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the consolidated financial
position of Atlantic Central Enterprises Limited as of February 28, 1997, and
the results of their operations, and their cash flows for the year ended
February 28, 1997, 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.  The
Company incurred a net loss of approximately $12,546,000, a loss from
continuing operations of approximately $10,316,000, a working capital deficit
of approximately $874,000 and utilized approximately $4,173,000 in cash for
operating activities for the year ended February 28, 1997.  These matters
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 1.  The consolidated financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

[1] The Company and Basis of Presentation 
 
[A] Atlantic Central Enterprises Limited ("ACE" or "The Company") was
incorporated under the laws of Bermuda on February 2, 1996 under the name
Bamburgh Limited.  Thereafter, on April 2, 1996, Bamburgh Limited changed its
name to Atlantic Central Enterprises Limited. 
 
ACE has not conducted any business operations since inception other than in
connection with the reorganization with Pharma Patch Public Limited Company
("Pharma Patch").  The reorganization, which took place on January 20, 1997,
involved Pharma Patch transferring to the Company all of its assets and having
the Company assume all of Pharma Patch's liabilities, in exchange for all the
outstanding common stock of ACE.  Immediately after the transfer Pharma Patch
commenced a voluntary liquidation and distributed all the Company's shares to
its shareholders.  As a result of the reorganization, Pharma Patch
shareholders received one common share of the Company for every 10 shares of
Pharma Patch owned.  This reorganization qualifies under Section 368(1)(1)(F)
of the Internal Revenue Code of 1986, as amended.  
 
ACE is currently engaged, through its subsidiary Vista Technologies, Inc.
("Vista"), in providing photrefractive keratectomy ("PRK") and other laser
vision correction ("LVC") facilities and services to the health care industry.

As a result of the restructuring, ACE is the successor in interest of Pharma
Patch plc.  Accordingly, "the Company" will be used interchangeably to refer
to ACE and Pharma Patch when describing operational history unless
specifically indicated. 

[B] Going Concern - The accompanying consolidated financial statements have
been prepared in conformity with generally accepted accounting principles,
which contemplates continuation of the Company as a going concern and
realization of assets and settlement of liabilities and commitments in the
normal course of business.  The Company has experienced significant net
losses, a loss from continuing operations of approximately $10,316,000, has a
working capital deficit of approximately $874,000 and utilized approximately
$4,173,000 in cash for operating activities for the year ended February 28,
1997. In addition, the Company has serious liquidity problems primarily due to
unsuccessful attempts to raise money both at the parent level and at the
subsidiary level and significant costs associated with the Company s failed
attempts to penetrate the North American vision correction market resulting in
losses from operations.  The Company and its subsidiaries are developing
business plans which when  implemented would develop opportunities in the
laser vision correction and automotive maintenance markets in North America
and/or Europe.  Vista's management is developing a business plan which takes
advantage of new trends in the laser vision correction business in both North
America and Europe.  Vista plans to concentrate on its four successful centers
in Italy and Sweden in the 1997-1998 fiscal year and focus on the reduction of
expenses at the head office level.  The Company also plans to sell a portion
of its marketable securities, obtain additional debt financing and focus on
revenue growth of its existing operations.

The financial statements do not include any adjustments that might be
necessary if the Company is unable to continue as a going concern.  The
continuation of the Company as a going concern is dependent upon the success
of these plans.  There can be no assurance of the success of these plans.
 
[C] Reorganization - On January 20, 1997, the shareholders of Pharma Patch
approved the following plan of reorganization with Atlantic Central
Enterprises Limited.  
 
ACE was initially capitalized in August 1996 by issuing 1,200,000 shares of
common stock to Pharma Patch for $12,000 in cash. 
 
Subsequent to the reorganization, ACE issued an additional 450,000 shares of
its common stock in exchange for the stock held by the stockholders of Pharma
Patch and dissolved the corporate charter of Pharma Patch.

[1] The Company and Basis of Presentation [Continued]  

[C] [Continued] - These transactions resulted in the elimination of the
16,541,570 ordinary shares of Pharma Patch and created 1,654,157 shares of
common stock (one share of ACE common stock for every 10 ordinary shares of
Pharma Patch) in ACE with a par value of $16,542.  As a result of the
difference between Pharma Patch's ordinary shares issued at par value
($2,343,914) and ACE's common stock issued at par value ($16,542) the premium
in excess of par value increased by $2,327,372  (Pharma Patch's par value per
ordinary share was Irish Pounds .01 and ACE's par value per common share is
US$ .01).  All per share amounts in this report have been restated to reflect
this reorganization. 
 
[D] Pharma Patch was incorporated under the laws of the Republic of Ireland in
January 1992.  Prior to July 1993, Pharma Patch had no significant assets or
operations.  Prior to fiscal 1997 the Company was mainly involved in the
research and development of transdermal drug delivery systems and skin
permeation technology.  The Company developed and patented proprietary
technology and secured licensing and product feasibility agreements through
research in this area.

[E] On November 15, 1995, Pharma Patch  sold substantially all of the
operating assets to Technical Chemicals and Products, Inc. ("TCPI") for a gain
of approximately $16.4 million. These assets included 11 U.S. patents relating
to transdermal drug delivery and skin permeation technology, license rights to
skin penetration enhancers and electronically assisted drug delivery,
proprietary information and trade secrets related thereto, certain licensing
and product feasibility agreements entered into by the Company and all of the
Company's fixed assets. TCPI also assumed the sublease of the research
facility occupied by the Company. 

In consideration for the purchased assets, TCPI issued an aggregate of 786,214
shares of its common stock with a fair value of $11,919,000 and satisfied the
$5,000,000 promissory note previously issued by the Company to Flora, Inc.
("Flora") (see note 7). As a result of this transaction, the Company owned
9.9% of TCPI's outstanding common shares and ceased performing research and
development work and other operations in the areas of skin penetration
enhancers and drug delivery systems.  

On January 16, 1996, the Company entered into a supplemental agreement with
TCPI, which amended certain provisions of the November 1995, asset purchase
agreement. TCPI had filed a Registration Statement on Form S-1 with the
Securities and Exchange Commission with respect to the sale of 1,800,000 TCPI
common shares (Offering). Pursuant to the terms of the supplemental agreement,
the Company executed a lock-up letter with the representative of the TCPI
Underwriters providing that it would not sell or otherwise dispose of any of
its shares of common stock for a period to expire 180 days following the
closing date of the Offering without their prior consent. As consideration for
the execution of the lock-up agreement, TCPI (i) terminated an existing
lock-up agreement covering TCPI common stock owned by the Company, executed in
connection with the asset purchase agreement; (ii) effective as of closing
date of the Offering, terminated the voting trust agreements, shareholders'
agreement and irrevocable proxy, executed in connection with the asset
purchase agreement which, among other things, limited the Company's ability to
vote or dispose of its shares of common stock; (iii) allowed the Company to
offer for sale 100,000 shares of this common stock in the Offering (plus up to
an additional 110,000 if the Underwriters over-allotment option is exercised);
(iv) effective as of the closing date of the Offering, issued to the Company a
two-year warrant to purchase 100,000 shares of common stock at an exercise
price equal to the per share Offering price; and (v) file a Registration
Statement on Form S-3 to register all of the remaining shares of common stock
owned by the Company after the Offering.  

[F] On March 21, 1996, the Company completed the acquisition of 61.3% of the
voting interest of Vista Technologies, Inc. ("Vista").  Vista provides photo
refractive keratectomy ("PRK") and other laser vision correction ("LVC")
facilities and services to the health care industry.

[1] The Company and Basis of Presentation [Continued]  

[F] [Continued] - The Company acquired its position in Vista by executing a
stock purchase agreement for 200,000 newly issued shares of Vista common stock
for a cash price of $500,000.  The Company and Vista executed an additional
agreement under which Vista provided 2,060,000 newly issued shares of its
common stock to the Company plus 500,000 Vista Class C common stock purchase
warrants.  In exchange, Vista received a $750,000 interest-free note due six
months after the transaction date and 200,000 restricted shares of TCPI common
stock previously held by the Company with a fair value on the date of the
transaction of $3,550,000 (original cost basis to the Company of $3,032,000). 
The Company paid the $750,000 note in full during the first quarter of fiscal
1997.  The Company also received an option to acquire 250,000 Vista shares at
$2.50 per share.  In a separate transaction, the Company agreed to provide
4,500,000 newly issued Ordinary Shares in exchange for a total of 900,000
shares of Vista's outstanding common stock owned by three shareholders.   

A summary of the consideration for both components of the Vista transaction
include the following:

                                                     ============

</TABLE>

The cost in excess of net assets acquired of approximately $4.5 million was
calculated utilizing the original carrying value of the TCPI investment
($15.16 per share).  The acquisition of Vista was recorded using the purchase
method of accounting resulting in goodwill of $4,500,000 which was being
amortized using the straight-line method over fifteen years beginning in March
of 1996.  At February 28, 1997, the Company's management determined that the
goodwill was impaired.  As a result, the Company wrote off goodwill of
approximately $4,300,000 after it determined that the unamortized balance of
goodwill could not be recovered through projected future discounted cash flows
over its remaining life [See Note 2].

During the year the Company exercised their 250,000 options to purchase an
additional 250,000 shares of Vista for cash consideration of $625,000.   The
company also purchased additional 13,800 shares on the open market for cash
consideration of $37,663. 

Since March 21, 1996, ACE's interest in Vista has been diluted by the issuance
of Vista stock to Vista's Regional affiliates.  At February 28, 1997, ACE
owned 54.14% of the issued and outstanding shares of Vista.  

[G] Regional Joint Ventures -Vista's business strategy during fiscal 1997 was
to expand in North America by organizing and sponsoring independently financed
regional enterprises (Regional Joint Ventures) in which Vista would obtain a
significant equity interest and long-term fee-based consulting arrangements.

[1] The Company and Basis of Presentation [Continued]  

Vista's negotiations to acquire interests in additional laser vision center
("LVC") operations, based primarily in Canada, were abandoned, Vista sold all
of its interest in a Regional Joint Venture formed to service the Northern
California market, and the Vista's equity ownership in a Regional Joint
Venture formed in March 1996 and based in Arizona was increased to 94%. 
Unsuccessful efforts by Vista's former management to obtain additional private
placement equity financing necessary to finance Vista's Regional Joint Venture
expansion plans and to support general and administrative expenses in North
America were terminated during March 1997.

Vista's management intends to reactivate a strategic expansion plan if a debt
compromise plan with Vista's creditors is proposed and accepted or convert the
debt obligation to an equity position (subject to shareholder approval) and if
significant additional capital is obtained.   

There can be no assurance that Vista will be successful in accomplishing these
objectives.  Pending further developments, Vista has been advised that its
controlling stockholder, ACE, plans to pursue a strategic plan of negotiating
to acquire or develop Regional Joint Ventures in the United States for laser
vision correction facilities and services.  Vista has been advised that if ACE
can successfully implement a strategy of North American expansion in the field
of laser vision correction, Vista anticipates that it will be provided a right
to acquire such operations at ACE's cost if Vista completes a debt compromise
plan with its creditors and if significant additional capital is obtained.  

  Investments by Vista in Regional Joint Ventures are summarized as follows:

  INVESTMENT IN VISTA LASER CENTERS OF MICHIGAN, INC.

  In November 1995, Vista issued 200,000 shares of its common stock in
  exchange for 200,000 shares of 5% Series B convertible preferred stock in
  Vista Laser Centers of Michigan, Inc. (VLC-Michigan), a development stage
  enterprise.  Effective July 18, 1996, Vista also acquired 100,000
  VLC-Michigan Series A preferred shares from a third party in exchange for
  100,000 shares of Vista's common stock with an estimated value of
  approximately $0.99 a share at the date of issuance.  Vista subsequently
  elected to convert all 300,000 shares of VLC-Michigan preferred stock into
  300,000 shares of VLC-Michigan common stock.  VLC-Michigan abandoned a
  proposed initial public offering in late 1996.  During December 1996,
  negotiations for VLC-Michigan to acquire an existing laser vision
  correction services business based in Windsor, Ontario, and to enter into
  related agreements with affiliates of the physician who owns the Windsor
  business, were terminated.  VLC-Michigan refunded stock subscriptions
  previously received from affiliates of that physician.  Vista subsequently
  agreed to accept 200,000 shares of its common stock owned by VLC-Michigan
  for cancellation, which have been returned to the Company's possession, in
  exchange for the cancellation of 200,000 shares of VLC-Michigan common
  stock then owned by Vista.  Vista also agreed to assume responsibility for
  the refund of a $9,500 stock subscription to VLC-Michigan paid by a
  director of the Company.

  As a result of these transactions, Vista owned 100,000 shares of
  VLC-Michigan common stock, representing 100% of the VLC-Michigan
  outstanding capital stock, as of February 28, 1997.  

  During the period from March 1996 through October 1996, there were various
  advances made by Vista to VLC-Michigan for VLC-Michigan initial public
  offering expenses plus approximately $510,800 of advances to finance
  equipment deposits and operating expenses of the businesses that
  VLC-Michigan proposed to acquire and develop.  In November 1996, the amount
  of $100,000 in such cash advances was refunded to Vista.  Vista is
  currently negotiating to obtain an accounting and/or refund of $410,800 of
  such advances as part of a proposed release and settlement of the
  obligations of Vista and VLC-Michigan, on the one hand, and affiliates of
  the physician who owns the Windsor business, on the other hand.  As of
  February 28, 1997, $285,800 of the advances have been written off and the
  VLC-Michigan cash balance of $125,000 has been consolidated.

  INVESTMENT IN VISTA LASER CENTERS OF THE SOUTHWEST, INC.
 
  In March, 1996, Vista issued 250,000 shares of its common stock in exchange
  for a subscription to 350,000 shares of 5% Series B convertible preferred
  stock in Vista Laser Centers of the Southwest, Inc. (VLC-Southwest), a
  development stage enterprise.  Effective July 18, 1996, Vista also acquired
  rights to 100,000 VLC-Southwest Series A preferred shares from a third
  party in exchange for 100,000 shares of Vista's common stock with an
  estimated value of approximately $0.99 a share at the date of issuance. 
  Vista subsequently elected to convert all of its rights to 450,000 shares
  of VLC-Southwest preferred stock into 450,000 shares of VLC-Southwest
  common stock and management affiliates of VLC-Southwest released the right
  to vote such shares by proxy.  VLC-Southwest abandoned a proposed initial
  public offering in late 1996.

  On October 1, 1996, Vista and VLC-Southwest agreed that Vista's account
  receivable of $383,634 for advances to VLC-Southwest would be extinguished
  in exchange for the surrender of 250,000 shares of Vista's common stock
  then held by VLC-Southwest.  This increased Vista's investment in
  VLC-Southwest by $145,634.  The agreement further provides that additional
  advances by Vista to VLC-Southwest after October 1, 1996 will be made in
  exchange Vista's investment in additional common stock of VLC-Southwest
  based upon a share price value of $3.00 per share of VLC-Southwest common
  stock.  As of March 31, 1997, Vista had advanced an additional $210,486 to
  VLC-Southwest as additional investment in VLC-Southwest common stock under
  this agreement.  The agreement will remain in effect as to additional
  advances until the earlier of completion by VLC-Southwest of a private
  placement offering of its securities to third parties or termination of
  that offering no later than March 31, 1997. As a result of the termination
  of the offering by VLC-Southwest, the agreement terminated and advances
  made by Vista to VLC-Southwest since October 1, 1996 will not be exchanged
  for additional shares of VLC-Southwest at $3.00 per share.

  As of October 1, 1996, Vista agreed to purchase a $100,000 VLC-Southwest
  note and 10,000 VLC-Southwest Class B warrants from Atlantic Central in
  exchange for a $100,000 note payable by Vista.  Vista also agreed to
  surrender the $100,000 VLC-Southwest note for cancellation in exchange for
  100,000 shares of VLC-Southwest common stock effective October 1, 1996.

  Under an agreement between Vista and VLC-Southwest, VLC-Southwest is
  entitled to use Vista's service mark for Vista laser centers and provides
  VLC-Southwest with exclusive rights to establish and operate laser vision
  correction service centers at locations within Arizona, Utah, Colorado, El
  Paso County in Texas and the City of Las Vegas, Nevada; the exclusive
  geographic rights of VLC-Southwest are subject to the establishment and
  maintenance of eight centers in those areas according to an agreed schedule
  in addition to an existing center operated by VLC-Southwest in Scottsdale,
  Arizona.  This agreement terminated on June 30, 1997.  VLC-Southwest is
  using Vista's service mark with Vista's authorization and a revised
  agreement providing VLC-Southwest with exclusive geographical rights has
  not been executed.

  As a result of these transactions, Vista owned 550,000 shares of
  VLC-Southwest common stock, representing 94% of the VLC-Southwest
  outstanding capital stock as of February 28, 1997, before giving effect to
  shares Vista may acquire as a result of additional advances by the Company
  to VLC-Southwest after October 1, 1996.

  of $100,000 for the repurchase of the remaining 100,000 shares of
  VLC-Pacific common stock then owned by Vista.  VLC-Pacific also agreed to
  issue a 9% promissory note in the principal amount of $160,838 to evidence
  its obligations for repayment of advances in that amount by Vista to
  VLC-Pacific.  Each of the VLC-Pacific promissory notes are due on the
  earlier of December 31, 1998 or ten days after successful completion of an
  initial public offering by VLC-Pacific.  

  As a result of these transactions, Vista did not own an equity interest in
  VLC-Pacific capital stock as of February 28, 1997.

  INVESTMENT IN VISTA LASER CENTERS OF THE NORTHEAST

  In May 1996, Vista issued 450,000 shares of its common stock in exchange
  for 500,000 shares of 5% Series B convertible preferred stock in Vista
  Laser Centers Metro Inc., doing business as Vista Laser Centers of the
  Northeast (VLC-Northeast), a development stage enterprise.  Effective July
  18, 1996, Vista also acquired 100,000 VLC-Northeast Series A preferred
  shares from a third party in exchange for 100,000 shares of Vista's common
  stock with an estimated value of approximately $0.99 a share at the date of
  issuance.

  In January 1997, Vista, Atlantic Central, VLC-Northeast and certain members
  of VLC-Northeast operating management and their affiliates entered into a
  settlement agreement to terminate all relationships between the parties. 
  Vista sold all of its equity investment in VLC-Northeast for the sum of
  $1.00 and agreed to assign to a nonrelated entity for the sum of $1.00 all
  prior advances and loans by Vista to VLC-Northeast in the aggregate amount
  of $511,460.  Vista further agreed: (i) to pay $50,000 as a settlement of
  prior obligations to VLC-Northeast; (ii) to pay VLC-Northeast an amount
  equal to $75,000 plus $6,271 in interest accrued on certain promissory
  notes previously issued by VLC-Northeast to Atlantic Central (and secured
  by a pledge of certain shares of Company's common stock owned by
  VLC-Northeast), against the receipt from Atlantic Central  of releases in
  favor Vista and of all collateral security claims to shares of Vista's
  common stock owned by VLC-Northeast; (iii) to advance $50,000 to an escrow
  fund for use by VLC-Northeast under prescribed conditions for expenses
  relating to its future capital-raising expenses, which advances are to be
  repaid to Vista in the event VLC-Northeast completes additional debt or
  equity financings in the aggregate amount of at least $500,000; and (iv) to
  pay $275,000 (of which $200,000 is to be deposited into an escrow account)
  from proceeds of a private placement offering of at least $2 million by
  Vista.

  VLC-Northeast has agreed to release its license to use Vista's service
  marks, to change the name of VLC-Northeast and signage to eliminate use of
  the "Vista" name by VLC-Northeast (subject to a non-assignable license to
  VLC-Northeast for use of certain promotional and marketing materials of the
  Company within the greater Toronto, Ontario area so long as such materials
  do not use the word "Vista" Vista's associated logo), and to return for
  cancellation 450,000 shares of Vista's common stock currently owned by
  VLC-Northeast at the time all escrow funds have been deposited by Vista. 
  Of the $200,000 in funds to be deposited into an escrow account, $50,000 is
  to be released to VLC-Northeast upon completion of actions necessary for
  termination of its use of the name "Vista" and Vista's service marks by
  July 1, 1997, and the remaining $150,000 is to be released to VLC-Northeast
  at the rate of $25,000 per month, except that any undisbursed escrow funds
  are to be refunded to Vista in the event VLC-Northeast completes additional
  debt or equity financings in the aggregate amount of at least $500,000.

  Vista has paid $150,000 under the settlement and will be obligated to
  deposit an additional $275,000 from proceeds of a private placement
  offering of at least $2 million by Vista.  Vista has also agreed to remain
  obligated as a guarantor of certain equipment lease and premises lease
  obligations of VLC-Northeast, subject to the agreement of VLC-Northeast to
  use its best efforts to obtain a release of such guarantees in the event of
  a change in control of VLC-Northeast or should Vista successfully complete
  a private placement offering of at least $2 million, failing which
  VLC-Northeast will agree to indemnify Vista for any liabilities incurred as
  a result of the guarantees.

  As a result of these transactions, Vista did not own an equity interest in
  VLC-Northeast capital stock and has written off its investments in
  VLC-Northeast as of March 31, 1997.

  MISCELLANEOUS

  In assigning values at the times of issuance of Vista's common stock issued
  to Regional Joint Ventures and to a third party, Refractive Services-800,
  Inc., originally issued to acquire Series A preferred shares in the
  Regional Joint Ventures, Vista gave consideration to nonrelated independent
  appraisals obtained on the value for the consideration received from the
  Regional Joint Ventures in exchange for such common stock, the estimated
  market value of Vista's common stock based upon recent private placements,
  the quoted price of Vista's common stock in the over-the-counter market,
  and the voting and other restrictions on the issued stock.

  Vista currently controls all of the board of directors of VLC-Michigan and
  VLC-Northwest and controls the board of directors of VLC-Southwest by
  virtue of Vista's controlling stock ownership.  Vista currently has no
  representation on the board of directors of VLC-Pacific or VLC-Northeast.

  As of February 28, 1997 ACE has an accumulated deficit of $18,692,005,
  total assets of $8,118,894 and total shareholders' equity of $306,293.
  ACE's majority owned subsidiary, Vista has an accumulated deficit of
  $22,142,284, total assets of $4,330,537, total shareholders deficiency of $
  2,094,820 and received a Going Concern opinion from its auditors for the
  twelve months ended March 31, 1997 (see Vista's March 31, 1997 10K for
  additional information).  ACE, including Vista, has not yet achieved
  profitable operations and there is no assurance that profitable operations,
  if achieved, could be sustained on a continuing basis. Further, the
  Company's future operations are dependent on the success of the
  commercialization efforts and market acceptability of the Vista business
  plan and other potential business ventures of the Company, together with
  the value derived from the TCPI investment securities.

[2] Significant Accounting Policies
 
These consolidated financial statements have been prepared in accordance with
generally accepted accounting principles ("GAAP") in the United States.  
   
[A] Principles of Consolidation - The consolidated financial statements
include the accounts of ACE and its wholly and majority owned subsidiaries in
Canada and in the United States. All significant intercompany balances and
transactions have been eliminated in consolidation.

The Company has consolidated its results for the year ended February 28, 1997
with the results of operations of Vista for the year ended March 31, 1997 in
accordance with  U.S. GAAP. 
 
Vista and its subsidiaries in Italy, Sweden, the Netherlands and the United
States have been consolidated at February 28, 1997 using their respective four
fiscal quarters ended March 31, 1997.  Vista's subsidiaries in Italy, Sweden
and the Netherlands were consolidated in Vista's March 31, 1996 financial
statements using the subsidiaries' respective fiscal year ends, which were
December 31, 1995.  The net income for the three month period ending March 31,
1996 for the Company's subsidiaries in Italy, Sweden and the Netherlands is
reflected in  the accumulated deficit for fiscal 1997 as a one-time adjustment
for the European operating subsidiaries to conform reporting periods.   ACE
did not consolidate Vista's financial statements for its year ended February
29, 1996, as controlling interest did not exist in Vista until March 1996. 
 
Because majority ownership was considered only temporary, the Vista's
investments in VLC-Michigan, VLC-Northwest and VLC-Southwest were accounted
for by the equity method through September 30, 1996.  Subsequent to September
30, 1996, the Company's plans with respect to these entities changed, and
majority ownership is no longer considered temporary.  Accordingly, these
entities have been consolidated as of February 28, 1997.

[2] Significant Accounting Policies [Continued]

[B] Cash and Cash Equivalents -All short-term, highly liquid investments with
maturities of three months or less at the date of purchase are considered to
be cash equivalents.  
 
[C] Risk Concentrations - Financial instruments that potentially subject the
Company to concentrations of credit risk include cash and cash equivalents
arising from its normal business activities.  ACE had $1,806,000 on deposit at
various institutions at February 28, 1997.  $147,000 of this amount was
federally insured against institution failure.  Vista had approximately
$533,000 on deposit in Italy and Sweden at February 28, 1997.  Italy and
Sweden do not have federal insurance on balances maintained in banks.  There
is no collateral in relation to deposits. 

[D] Investment Securities - Investment securities at February 28, 1997 consist
of equity securities. The Company's equity securities are classified as
available-for-sale securities under the provisions of Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities." The Company's equity securities are recorded at fair value
based on quoted market prices.  

The carrying amount of other financial instruments approximates fair value
generally due to the short-term  maturity of these instruments.  When sold,
the actual cost of these investments is used when calculating  any gain
(loss). 

[E] Fixed Assets - Fixed assets are recorded at acquisition cost. The Company
provides depreciation and amortization at rates, which are expected to charge
operations with the cost of the assets over their estimated useful lives
ranging from three to ten years. 
            
[F] Impairment - Certain long-term assets of the Company are reviewed at least
annually as to whether their carrying value has become impaired, pursuant to
guidance established in Statement of Financial Accounting Standards (SFAS) No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of.  Management considers assets to be impaired if the
carrying value exceeds the future projected cash flows form related operations
(undiscounted and without interest charges).  If impairment is deemed to
exist, the assets will be written down to fair value or projected discounted
cash flows from related operations.  Management also reevaluates the periods
of amortization to determine whether subsequent events and circumstances
warrant revised estimates of useful lives.  As of February 28, 1997, the
Company expects these assets to be fully recoverable. 

[G] Minority Interest - On March 21, 1996, the Company acquired 61.3% on the
issued and outstanding common stock of Vista.  In May 1996, Vista issued
1,450,000 shares of its common stock to acquire interests in three
developmental stage companies involved in providing PRK and other LVC
facilities and services to the health care industry. 

In June 1996, Vista sold 100,000 common shares for cash proceeds of $212,500. 
In May 1996 Vista issued 1,450,000 of its shares to acquire 1,500,000 Series B
Convertible Preferred shares of 3 regional affiliates.  In July 1996, Vista
issued 520,000 shares to acquire 520,000 Series A preferred shares of five
regional affiliates.  Pharma Patch exercised its options to acquire 250,000
Vista shares for $625,000 cash in July 1996.  In October and December of 1996
1,450,000 of Vista's shares were returned to the Vista for cancellation from
the 3 regional affiliates.  In December 1996, 98,000 of Vista shares where
issued in exchange for a $122,500 note.  The shares issued by Vista, adjusted
for the shares acquired by ACE, reduced the Company's ownership in Vista from
61.3% to 54.14% at February 28, 1997. 

On March 21, 1996, the minority interest associated with the Company's
investment in Vista was $2,135,895.  During the year Vista had losses of
$6,999,981.  ACE's minority interest portion of this loss was 45.86% at
February 28, 1997, or $3,210,191.  In accordance with US GAAP, the Company
charged $2,135,895 against minority interest on the balance sheet, bringing
ACE's minority interest in Vista to a zero balance and charged the remaining
$1,074,296 to ACE's statement of operations.

[2] Significant Accounting Policies [Continued]

[G] Minority Interest [Continued]  - The remaining $211,410 of minority
interest on ACE's balance sheet relates to Vista's minority shareholders
proportionate share of the equity in Vista Italy and Vista Southwest.  On
February 28, 1997 Vista owned 75% of the capital stock of Vista Italy and 94%
of the capital stock of Vista Southwest. 

[H] Foreign Currency Translation - Assets and liabilities stated in functional
currencies other than the U.S. dollar are translated at the year-end exchange
rate and revenues and expenses at the average rate of exchange for the year.
Foreign exchange gains and losses from transactions in currencies other than
the applicable functional currency are reflected in income during the year.
Gains or losses arising on the translation of financial statements give rise
to a cumulative translation adjustment, which is included as a component of
shareholders' deficiency.  

As a result of the Company's translation and consolidation of Vista's
financial statements at February 28, 1997, a balance of $159,431 relating to
foreign currency translation exists.  This amount arises from Vista's European
subsidiaries. 

[I] Offering Costs - Costs associated with public and private offerings by the
Company of its stock have been charged against the proceeds of the offering. 
Any costs associated with an abandoned financing are charged against income in
the year the financing is abandoned. 
 
[J] Revenue Recognition - Revenues for the period March 21, 1996 to February
28, 1997, the period the Company consolidated Vista's results, are recognized
when photorefractive keratectomy related facility and service fees are
performed.  Product development fees in the prior years are included in
discontinued operations and represent charges to third parties for research
and development work performed by the Company and is recorded in the period
the fees are earned. 
 
[K] Stock Compensation - The Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 123,
Accounting for Stock Based Compensation in October 1995.  SFAS No. 123 uses a
fair value based method of accounting for stock options and similar equity
instruments as contrasted to the intrinsic valued based method of accounting
prescribed by Accounting Principles Board ("APB") Opinion No. 25, Accounting
for Stock Issued to Employees.  The Company adopted SFAS No. 123 on March 1,
1996 for financial note disclosure purposes and will continue to apply APB
Opinion No. 25 for financial reporting purposes.

[L] Use of 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 expenses during the
reporting period.  Actual results could differ from those estimates.  
   
[M] Operations in Foreign Countries - The Company is subject to numerous
factors relating to conducting business in foreign countries (including,
without limitation, economic, political and currency risks), any of which
could have a significant impact on the Company's operations. 
 
[N] Advertising Costs - Advertising costs are expensed as incurred.  The
Company incurred advertising expense of approximately $415,000 for the year
ended February 28, 1997.

[2] Significant Accounting Policies [Continued]
   
[O] New Authoritative Pronouncements - The FASB has issued SFAS No. 128,
Earnings Per Share and FASB No. 129, Disclosure of Information About Capital
Structure.  Both are effective for financial statements issued for periods
ending after December 15, 1997.  SFAS No. 128 simplifies the computation of
earning per share by replacing the presentation of primary earnings per share
with a presentation of basic earnings per share.  The statement requires dual
presentation of basic and diluted earnings per share by entities with complex
capital structures.  Basic earnings per share include no dilution and is
computed by dividing income available to common stockholders by the weighted
average number of shares outstanding for the period.  Diluted earnings per
share reflect the potential dilution of securities that could share in the
earnings of an entity similar to fully diluted earnings per share. 

While the Company has not analyzed SFAS No. 128 sufficiently to determine its
long-term impact on per share reported amounts, SFAS No. 128 should not have a
significant effect on historically reported per share loss amounts. 

SFAS No. 129 does not change any previous disclosure requirements but, rather,
consolidates existing disclosure requirements for ease of retrieval. 

The FASB has issued SFAS No. 130, "Reporting Comprehensive Income."  SFAS No.
130 is effective for fiscal years beginning after December 15, 1997.  Earlier
application is permitted.  Reclassification of financial statements for
earlier periods provided for comparative purposes is required.  SFAS No. 130
is not expected to have a material impact on the Company.  

The FASB has issued SFAS No. 131, "Disclosures About Segments of an Enterprise
and Related Information."  SFAS No. 131 changes how operating segments are
reported in annual financial statements and requires the reporting of selected
information about operating segments in interim financial reports issued to
shareholders.  SFAS No. 131 is effective for periods beginning after December
15, 1997, and comparative information for earlier years is to be restated. 
SFAS No. 131 need not be applied to interim financial statements in the
initial year of its application.  SFAS No. 131 is not expected to have a
material impact on the Company. 

[3] Investment Securities 
 
Investment securities at February 28, 1997, consisted of equity shares
acquired by the Company in the TCPI asset purchase agreement (see note 1(d)). 
On November 15, 1995, the Company acquired 786,214 common shares of TCPI with
a fair value of $11,919,000 or $15.16 per share.  As of February 28, 1997, the
TCPI stock was trading at $9.125 per share.  In the Company's transaction with
Vista on March 21, 1996, Vista received 200,000 shares of the Company's TCPI
stock as part of the consideration for the purchase of Vista stock at the
company's cost basis of $15.16.  In April 1996, the Company sold 210,000 TCPI
shares for net proceeds of $2,928,697 and recorded a loss of $255,100.  In
January and February 1997, the Company sold 116,214 TCPI shares in open market
transactions for net proceeds of $1,052,931 and recorded a loss of $963,776. 
The actual cost was used in determining the loss on sale of marketable
securities.  As of February 28, 1997, the Company held 260,000 shares of TCPI
stock with a fair market value of $2,372,500 and a recorded unrealized loss of
$ 1,569,000 as a separate component of shareholders' equity.

  i. The principal amount and accrued interest on the 12% convertible
     notes due in 1998 are convertible, at the option of the holder, into
     shares of Vista's common stock at a conversion price of $5.00 per
     share.  These notes are collateralized by 51% of the issued and
     outstanding shares of Vista-Sweden common stock.  Vista-Sweden is
     also committed under a royalty agreement with each noteholder
     expiring on May 31, 1998.  Under the royalty agreements, Vista-Sweden
     will pay royalties to each noteholder for each incremental PRK
     procedure performed by Vista-Sweden during the three years ended May
     31, 1996, 1997 and 1998.  Vista has not accrued any royalties for
     1997 or 1996. 

  ii.     The 12% secured promissory note is collateralized by a security
          interest in all of the assets of Vista.  The 12% promissory note was
          to mature on June 30, 1997.  The holder of the note has verbally
          agreed to extend the term.  Definitive agreements revising the note
          are expected to be executed by April 30, 1998 [See Subsequent Event
          Note 17A].

[6] Notes Payable [Continued]

  iii.    In 1991 and 1993, Vista-Italy and another company in the laser vision
     correction service industry entered into agreements to license
     trademarks and develop territorial marketing strategies. The
     companies exchanged shares of their respective common stock as
     consideration under the agreements.  In 1993, the other party filed
     suit for termination of these agreements and a default judgment was
     entered in their favor.  In connection with this judgment,
     Vista-Italy canceled the shares of the common stock Vista-Italy had
     issued in the exchange, wrote-off the value of the other company's
     shares which had been issued to Vista-Italy and recorded an accrued
     liability for $175,000 equal to the principal amount of the default
     judgment.  The plaintiff has instituted legal proceedings in Italy
     seeking to collect the cash portion of its default judgment plus
     interest and costs. 

There were no restrictions or covenants on the note agreements.

[8] Fair Value of Financial Instruments
 
The carrying value of notes payable included in current liabilities
approximates fair value because of their short maturities.  The carrying
amount of long term notes receivable, notes payable and notes payable related
party included in non-current liabilities approximates their fair value
because they bear interest at a rate that approximates the Company's cost of
capital. 

[9] Leases, Commitments and Contingencies

Vista leases equipment, vehicles and office space under non-cancelable
operating leases and leases certain equipment under capital leases.

Facilities and Equipment Lease Guarantees for VLC- Northeast 
 
Vista has executed guarantees of certain equipment lease and premises lease
obligations of VLC-Northeast, subject to the agreement of VLC-Northeast to use
its best efforts to obtain a release of such guarantees in the event of a
change in control of VLC-Northeast or should Vista successfully complete a
private placement offering of at least $2 million, failing which VLC-Northeast
will agree to indemnify the Company for any liabilities incurred as a result
of the guarantees.   The equipment lease guarantee executed on October 25,
1996 is for a VISX Star laser system with an initial value of $809,000.  The
equipment is to be used exclusively by VLC-Northeast in Toronto, Ontario, and
VLC-Northeast is primarily obligated to make all equipment lease payments. 
Vista does not own a beneficial interest in the equipment or in proceeds from
the  use of the equipment.  The premises lease executed on March 21, 1996 is
for a rental of approximately $9,058 per month expiring on May 14, 2006. 

Insurance and Indemnification

Use of laser systems by health care professionals using laser equipment and
other laser vision correction services may give rise to claims against the
Company or its affiliates by persons alleging injury.  The Company's
subsidiaries generally do not currently have malpractice liability insurance
due to limited capital resources.

The Company believes that claims alleging defects in laser systems will be
covered by manufacturers' warranties and the manufacturer's product liability
insurance, and that the Company and its affiliates could take advantage of
such insurance by adding such suppliers to potentially adverse lawsuits. 
There can be no assurance that laser suppliers will carry product liability
insurance or that any such insurance will be adequate to protect the Company.

Generally speaking, the policy of the Company's operating subsidiaries and
regional joint ventures is to require that ophthalmologists who perform laser
procedures by use of laser vision correction equipment maintain their own
professional liability insurance.
 
Lease commitments relating to abandoned equipment 
 
On November 15, 1996, Vista entered into an equipment lease for a VISX 20/20B
excimer laser system with an initial value of $267,500, which represents the
total lease payments of $317,145 less interest of $76,395.  The equipment was
leased for the benefit of London Place Eye Center, Inc. ("LPEC"), an affiliate
of Dr. Donald G. Johnson, former Chairman of the Board and a former director
of Vista.   LPEC has guaranteed the obligations of the Vista under this
equipment lease.  The equipment is to be used exclusively by LPEC in British
Columbia, and LPEC has agreed to make all equipment lease payments.  Vista
will not own a beneficial interest in the equipment or in proceeds from use of
the equipment unless LPEC defaults in its obligations to make equipment lease
payments.  The Company reflects the lease obligation of $251,533 and a
long-term receivable from the related party of $248,021 at February 28, 1997 
 
On October 19, 1996, Vista and LPEC executed a lease guarantee for an
equipment lease entered into by VLC-Northwest for a VISX Star laser system
with an initial value of $525,000, which represents the minimum future lease
payments of $720,000 less interest of $247,500.  The equipment was leased for
the benefit of LPEC.  The equipment is to be used exclusively by LPEC in
British Columbia, and LPEC has agreed to make all equipment lease payments. 
Vista and VLC-Northwest will not own a beneficial interest in the equipment or
in proceeds from use of the equipment unless LPEC defaults in its obligations
to make equipment lease payments. Vista reflects the lease obligation of
$514,366 and a long-term receivable from the related party of $485,041 at
February 28, 1997.

[9] Leases, Commitments and Contingencies [Continued]

Lease Commitments Relating to Abandoned Equipment [Continued]

On March 29, 1996, Vista signed a lease guarantee for an equipment lease by
LPEC of a VISX Star laser system with an initial value of $450,000.  Vista
does not own a beneficial interest in the equipment or in proceeds from use of
the equipment.

Vista entered into these equipment lease arrangements as an accommodation to
LPEC during the course of continuing negotiations for the purchase of LPEC
Vista subject to obtaining additional financing required to make such an
acquisition.  Negotiations to acquire LPEC were terminated in late 1996 and
Vista remains contingently liable as to the lease obligations and guarantee.

Litigation with Former Officers as to Severance Obligations 
 
In June 1997, Vista was named as the defendant in a civil action filed in
California state court by two former executive officers.  The complaint
alleges that Vista breached written employment agreements with each of the two
executives, both of whom were terminated as employees of Vista on March 6,
1997, and seeks damages of $231,073 plus interest and costs for Vista's former
President, damages of $241,902 plus interest and costs for the Vista's former
Executive Vice President, and restoration of stock options previously issued
to the executives under the terms of their employment agreements.  

Vista's written employment agreement with its former President provided he
would be entitled to severance benefits if his employment was involuntarily
terminated, other than for cause, death or disability, equal to (i) a lump-sum
payment equal to his annual base salary of $175,000, (ii) continuation of
insurance benefits for life, health, dental and long-term disability for a
period of 12 months after employment termination, and (iii) continued vesting
of his outstanding stock options for a period of 12 months after employment
termination. Vista's written employment agreement with its former Executive
Vice President provided he would be entitled to severance benefits if his
employment was involuntarily or constructively terminated, other than for
cause, death or disability, equal to (i) a lump-sum payment equal to his
annual base salary of $175,000, and (ii) continuation of insurance benefits
for life, health, dental and long-term disability for a period of 12 months
after employment termination.

Vista intends to vigorously contest claims of the plaintiffs for damages based
upon Vista's claim that their employment was terminated for cause.  However,
these proceedings are at a preliminary stage and no discovery has taken place. 
Special counsel engaged to represent Vista accordingly has advised it cannot
render an opinion as to whether the likelihood of an adverse determination
would be remote, reasonably possible or probable, until discovery proceedings
have been conducted.  Vista has accrued a liability for these legal
proceedings.  An adverse determination in these proceedings would have a
material adverse effect on the current financial condition of Vista. 

Legal Judgement
 
In 1991 and 1993, Vista-Italy and another company in the laser vision
correction service industry entered into agreements to license trademarks and
develop territorial marketing strategies. The companies exchanged shares of
their respective common stock as consideration under the agreements.  In 1993,
the other party filed suit for termination of these agreements and a default
judgment was entered in their favor.  In connection with this judgment,
Vista-Italy canceled the shares of  the common stock Vista-Italy had issued in
the exchange, wrote-off the value of the other company's shares which had been
issued to Vista-Italy and recorded an accrued liability for $175,000 equal to
the principal amount of the default judgment.  The plaintiff has instituted
legal proceedings in Italy seeking to collect the cash portion of its default
judgment plus interest and costs.

Other Litigation 
 
Vista and the Company, from time to time, may be a defendant in various legal
proceedings other than that noted above.  In particular, a case was dismissed
without prejudice  which alleged damages for economic interference and which
sought injunctive relief preventing Vista from being affiliated with a certain
doctor.  However, such dismissal leaves open the possibility that the claims
can be re-filed in the future.  In the opinion of management, the final
outcome of any such current proceedings will not have a material effect on the
financial position, results of operations, or cash flows of Vista and the
Company.  Management's opinion of the above proceedings, however, may change
in the near term due to the uncertainty of the legal process.

[10] Capital Stock 
 
Stockholders' equity has been retroactively restated to reflect the
reorganization with ACE for the periods presented. These transactions resulted
in the elimination of the 16,541,570 ordinary shares of Pharma Patch and
created 1,654,157 shares of common stock (one share of ACE common stock for
every 10 Ordinary shares of Pharma Patch) in ACE with a par value of $16,542. 
As a result of the difference between Pharma Patch's ordinary shares issued at
par value ($2,343,914) and ACE's common stock issued at par value ($16,542)
the premium in excess of par value increased by $2,327,372  (Pharma Patch's
par value per ordinary share was Irish Pounds .01 and ACE's par value per
common share is US$ .01).  All per share amounts in this report have been
restated to reflect this reorganization.   However, retained earnings was not
restated as no assignment is required as a result of the restructuring. 

The authorized and issued Common Shares of ACE for the 1997 and 1996 fiscal
years are as follows:
   
Authorized -The Company has authorized 50,000,000 Common Shares, par value
$.01 representing an aggregate value of $500,000.

  (v)       The reorganization of the Company resulted in the shareholders of
     Pharma Patch receiving one common share in Ace for every ten
     ordinary shares held in Pharma Patch immediately prior to the
     transaction.  ACE common shares have a par value of $ .01 each. 
     All stock options of Pharma Patch were canceled as a result of the
     reorganization.  There are currently no stock options issued for
     ACE.

  (vi)      On December 18, 1996, ACE offered to the holders of Pharma Patch's
     outstanding Class A, Class B, Class C and/or Class D Warrants the
     opportunity to exchange up to 32,023 shares of common stock of ACE
     at a rate of one ACE share for each 100 Class A, B, C and D
     Warrants.  The exchange offer expired on May 30, 1997 and as a
     result 15,230 shares of ACE were issued to holders of Pharma Patch
     warrants.

[11] Earnings (Loss) Per Share
 
The net earnings (loss) per share calculations are based on the weighted
average number of shares outstanding during the year.
   
EPS calculations for fiscal 1997 has been restated to reflect the
reorganization between Pharma Patch and ACE. 

[12] Income Taxes
 
Deferred income taxes reflect the net tax effects of (a) temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes, and (b) operating loss
and tax credit carryforwards.  ACE had research and development expenses not
claimed for income tax purposes of approximately $2,870,000, available to
reduce taxable income of ACE in future years. Due to the significant
uncertainty relating to the Company's ability to utilize these expenses to
offset taxable income, valuation allowances are recognized to offset all of
the deferred tax assets relating to these expenses. These unclaimed research
and development expenses may be carried forward indefinitely for income tax
purposes.

[12] Income Taxes [Continued]

Vista has net operating losses carryforwards totaling approximately
$8,200,000, which expire between the years 2007 and 2012.  As of February 28,
1997, ACE may not have available the Vista NOL's to offset against future ACE
taxable income, however, Vista's NOL are available against future Vista
income. Vista's use of these carryforwards may be limited by Section 382 of
the Internal Revenue Code. 

ACE is not required to file a US consolidated income tax return.  Accordingly,
the net operating loss carryforwards of Pharma Patch may not be available to
reduced future taxable income as a result of the Company's reorganization in
January of 1997 [See Note 1C].

[13] Related Parties  
 
[A] Stockholder Agreement - In 1993, the Company entered into an agreement,
which expires on December 31, 2011, with a stockholder whereby the Company has
granted the licensee certain production and distribution rights to a
technology that the Company still owns after the TCPI transaction, but which
is not expected to be pursued for commercialization.  No fee revenue was
recognized in fiscal 1997 and 1996.  

[B] Vista's Agreements with Refractive Services-800, Inc. - From July 1995
through June 1996, a foreign corporate investor named Refractive Services-800,
Inc. provided at least $100,000 in initial seed capital to each of five
Regional Joint Ventures (for an aggregate investment of $520,000) to finance
initial organizational expenses and costs of negotiating agreements with
vision care professionals and seeking additional financing.  In exchange for
that investment, and in view of the high risks associated with a start-up
enterprise, Refractive Services-800, Inc. received shares of a 10% Series A
convertible preferred issue of the Regional Joint Venture with a liquidation
preference equal to five times its cash investment in four Regional Joint
Ventures and six times its cash investment in one other Regional Joint
Venture.

Vista has been advised that a former chief executive officer of the Company,
Mr. Jac. J. Lam, renders financial advisory services to Refractive Services-
800, Inc.  Certain other clients of Mr. Lam and an entity owned by Mr. Lam,
Quintillion B.V., have previously invested in debt and equity securities of
Vista and ACE.

Vista negotiated an agreement effective July 18, 1996 to acquire the Series A
preferred shares owned by Refractive Services-800, Inc. in all five of these
Regional Joint Ventures in exchange for 520,000 shares of Vista common stock. 
In addition, Vista agreed to purchase all of the capital stock in Refractive
Services 800 Corp., a Nevada corporation, for $50,000 from Refractive
Services-800, Inc.  Refractive Services-800, Inc. organized Refractive
Services 800 Corp. to acquire rights to, and offer the use of, certain 800 and
900 telephone numbers for telemarketing purposes at the election of Regional
Joint Ventures.

In assigning value to the Company's common stock issued to Refractive
Services-800, Inc., Vista gave consideration to an independent appraisal
obtained on the value of the consideration received from the Regional Joint
Ventures in exchange for Vista's common stock, the estimated market value of
Vista's common stock based upon recent private placements, the quoted price of
Vista's common stock in the over-the-counter market, and the voting and other
restrictions on the issued stock.

[C] Agreement to Purchase Assets and Assume Lease Obligations  - On February
1, 1996, Vista entered into an asset purchase and lease assumption agreement
with a related party for an excimer laser system. The purchase price for the
asset was $75,000 in cash, a $96,591 promissory note with annual interest at
8% originally due May 31, 1996, and the assumption of outstanding obligations
under the existing lease on the laser, including future lease payments not to
exceed $328,409.  Subsequent to February 1, 1996, Vista replaced this laser
with newer technology resulting in a charge to the statement of operations in
the amount of $446,636 for the impairment of an idle asset.  As of March 31,
1997, $80,000 of the note payable for $96,591 had been paid.  The balance of
the note has been forgiven.

[13] Related Parties [Continued]

[D] Agreements with Executive Officers - On January 31, 1996, Vista hired a
new chief executive officer who was granted five-year options to purchase
300,000 shares of common stock under Vista's 1994 Stock Option Plan
exercisable at $2.50 per share.  On October 22, 1996, Vista also granted this
officer a five-year option to purchase 600,000 shares of common stock under
Vista's 1994 Stock Option Plan exercisable at $2.625 per share in anticipation
of a proposed financing.  The services of this employee were terminated for
cause in March 1997 and, therefore, these options were canceled.

Effective November 1, 1996, Vista hired a new chief operating officer who was
granted a five-year option to purchase 500,000 shares of common stock under
Vista's 1994 Stock Option Plan exercisable at $2.75 per share and purchased
for the sum of $100 a total of 100,000 Class G nontransferable common stock
purchase Warrants exercisable until December 31, 2001, unless earlier called
for redemption, at an exercise price of $2.625 per share.  The services of
this employee were terminated for cause by the Company in March 1997 and,
therefore, these options were canceled.

The exercise price of options and warrants were equal to or above the fair
market value of the common stock at the date of grant.

[E] Long-term Receivable - Related Party - Vista and a wholly-owned subsidiary
are parties to two lease agreements for two excimer vision correction lasers. 
Vista is not using the lasers, nor does Vista receive any benefit from the
procedures performed on these lasers.  The lasers are in the possession of a
company formerly affiliated with Vista as a Regional Joint Venture company. 
As Vista is party to the leases, the lease obligations are reflected on the
Company's financial statements as current and as long-term debt.  The lease
payments are guaranteed and made by the formerly affiliated Regional Joint
Venture company directly to the lessor.  The Company reflects the lease
obligations of $765,899 and a Long-Term Receivable from the related party of
$733,062 at March 31, 1997.

[14] The 1996 Stock Option Plan

On February 2, 1996, the Company's Board of Directors proposed the 1996 Stock
Option Plan [Option Plan] that was approved by the stockholders of the Company
in February 1996.  The purpose of the Option Plan is to permit the Board or a
Committee of the Board the flexibility of granting options of the Company's
common stock in lieu of cash to compensate officers, directors, employees and
other individuals acting as professionals, consultants and/or advisers to the
Company for services rendered to the Company and its subsidiaries.  A total of
350,000 shares of common stock are available for payment of compensation under
the Option Plan. No awards under the Option Plan have been made.

[17] Subsequent Event

[A] Promissory Note - Vista has been negotiating with the holder of a 12%
promissory note for $300,000 who has verbally agreed to extend the maturity
date of the 12% promissory note. Definitive agreements for the 12% promissory
note extension are being prepared and management anticipates that they will be
executed by April 30, 1998.

[B] First American AMO - In May 1997, Ace entered into an agreement to form a
new corporation, First American AMO ["AMO"], which is located in Palm Harbor,
Florida.  Ace agreed to fund AMO up to $450,000 prior to separate outside
funding of AMO.  Ace owns 83% of the issued and outstanding common stock of
AMO upon signing of this agreement.  AMO is an automotive maintenance
organization that improves the efficiencies of fixing a car.

[C] Sale of Marketable Securities - Between March 1, 1997 and July 3, 1997,
the Company sold 35,000 shares of TCPI common stock with net proceeds to the
Company of approximately $360,000.

[18] Subsequent Events [Unaudited]

[A] Shares fraudulently Issued - On December 12, 1997, management of the
Company discovered that its former U.S. counsel, fraudulently caused 960,000
newly issued and freely-tradeable shares of the Company's common stock to be
issued without the prior authorization or knowledge of the Company's board of
directors and management to his affiliate or to his brokerage account in
Canada, during the period from March 25, 1997 through July 31, 1997.  The
Company's legal counsel believes that it is probable the Company will incur a
loss contingency for the 960,000 shares of its common stock fraudulently
issued without consideration at the sole instructions of the former counsel. 
The Company is seeking a judgement for compensatory damages in the amount of
approximately $750,000 in legal fees and costs paid by the Company to the
former counsel during the period from 1993 to 1997 while he fraudulently
represented himself to be a licensed attorney, damages for the 960,000
fraudulently issued shares of the Company's common stock, and other
compensatory, punitive and exemplary damages.

<PAGE>
ATLANTIC CENTRAL ENTERPRISES LIMITED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- -----------------------------------------------------------------------------

[18] Subsequent Events [Unaudited] [Continued]

[A] Shares fraudulently Issued [Continued] - The Company has assigned a value
of $400,000 for the 960,000 shares fraudulently issued and will charge
operations with the value calculated using the market value on the day the
shares were issued.  It's the Company's intention to pursue legal action where
it will seek the return and cancellation of these 960,000 shares or other
restitution equivalent to the estimated fair value of the 960,000 shares.

Based upon extensive investigation of documents and other information provided
to counsel with respect to these proceedings, it is counsel's opinion that the
Company has meritorious causes against the former counsel and it is also their
opinion that it is probable the Company ultimately will be successful in
obtaining final judgments in the Company's favor against the former counsel
for an amount in excess of $1,250,000.  The ability of the Company to realize
on any such judgements, if successfully obtained, will be dependent upon the
Company's ability to locate and levy upon assets of the former counsel.  At
hearings held in December 1997 and January 1998, orders of preliminary
injunction were issued by a U.S. Federal district court and a court in British
Columbia restraining the transfer of assets from accounts with any financial
institutions maintained by the former counsel and certain corporate entities
controlled by the former counsel.  Pursuant to those orders, approximately
$220,000 of cash and securities in accounts maintained by Mr. Quinn have been
frozen.  The former counsel has filed responsive pleadings in the litigation
proceeding denying liability. 

In addition, the Company is investigating potential claims against other third
parties than may have aided and abetted the former counsel with respect to the
one or more of the causes of action asserted by the Company in the litigation
proceedings.  In addition to the former counsel and two entities believed to
be under his control, the Company's transfer agent has been named and served
as a defendant in the litigation proceedings.  A motion to dismiss the
proceedings against the transfer agent was denied by the federal district
court in this case, and the transfer agent has filed an answer denying
liability.  Based upon the information obtained, it is counsel's opinion it is
probable the Company has a meritorious cause of action against the transfer
agent.

[B] Asset Purchase Agreement - In July 1997, Vista Southwest entered into an
asset purchase and lease assumption agreement whereby Vista Southwest agreed
to purchase certain equipment for a total purchase price of $411,860,
consisting of $50,000 in cash payments, $361,860 in a promissory note with
annual interest of 8%.  The principal and interest on the note is due the
earlier of June 30, 1999 or 30 days following the close of an offering of
securities of Vista Southwest or Vista Technologies, Inc. with net proceeds of
not less than $2,000,000.  The estimated fair value of the acquired equipment
is $120,000.  Therefore, goodwill of approximately $292,000 was recorded on
this transaction.

Also in July 1997, ICON Vision Centers, Inc., a wholly owned subsidiary of the
Company, entered into an asset purchase agreement to purchase certain fixed
assets and inventory for a total purchase price of $128,000, consisting of
$25,600 in cash and a $102,400 noninterest bearing promissory note  The note
has monthly payments of $3,200 and will be paid in full by April 30, 2000. 
The estimated fair value of the inventory and fixed assets is approximately
$50,000.  Therefore, goodwill of approximately $78,000 was recorded on this
transaction.

[C] Sale of TCPI Marketable Securities - Between July 4, 1997 and December 31,
1997, the Company sold an additional 140,050 shares of TCPI common stock with
net proceeds to the Company of approximately $1,316,000.  Proceeds were
utilized for operations and to purchase additional investments through
December 31, 1997.  The sale of TCPI stock subsequent to March 1, 1997
resulted in a net loss of approximately $1,000,000 for the Company.  As of
February 28, 1998, the Company had 43,850 shares of TCPI.

[D] Additional Debt Financing -  Subsequent to year end, ACE opened a margin
account with its broker and borrowed funds against its holdings of TCPI
shares.  At February 28, 1998, there was no balance owing on the margin
account.

                      SHARE CAPITAL AND SHARE RIGHTS

3.      (a)   The authorised share capital of the Company at the date of

                          MODIFICATION OF RIGHTS

5.      Subject to the Companies Acts, all or any of the special rights attached
        to any class of shares for the time being issued may from time to time
        (whether or not the Company is being wound up) be altered or abrogated
        with the consent in writing of the holders of not less than seventy five
        percent of the issued shares of that class or with the sanction of a
        resolution passed at a separate general meeting of the holders of such
        shares voting in person or by proxy. To any such separate general
        meeting, all the provisions of these Bye-Laws as to general meetings of
        the Company shall mutatis mutandis apply, but so that the necessary
        quorum shall be two or more persons holding or representing by proxy
        one-third of the issued shares of the relevant class, that every holder
        of shares of the relevant class shall be entitled on a poll to one vote

        shares shall not, unless otherwise expressly provided in the rights
        attaching to or the terms of issue of such shares, be deemed to be

        therewith.

<PAGE>
                                  SHARES

7.      Unless otherwise determined by a resolution of the Company in general
        meeting, any shares unissued at the date of adoption of these Bye-Laws
        and any shares hereafter created and forming part of the equity share
        capital of the Company and any other securities convertible into such
        equity share capital shall be under the control of the Directors who may
        allot grant options over or otherwise dispose of the same to such
        persons (including the Directors themselves) on such terms and at such
        times as they think proper provided that no share shall be issued at a
        discount to its par value.

8.      The Board may in connection with the issue of any shares exercise all
        powers of paying commission and brokerage conferred or permitted by law.

9.      Except as ordered by a court of competent jurisdiction or as required by
        law, no person shall be recognised by the Company as holding any share
        upon trust and the Company shall not be bound by or required in any way
        to recognise (even when having notice thereof) any equitable,
        contingent, future or partial interest in any share or any interest in
        any fractional part of a share or (except only as otherwise provided in
        these Bye-Laws or by law) any other right in respect of any share except
        an absolute right to the entirety thereof in the registered holder.


                               CERTIFICATES

10.     The preparation, issue and delivery of certificates shall be governed by
        the Companies Acts.  In the case of a share held jointly by several
        persons, delivery of a certificate to one of several joint holders shall
        be sufficient delivery to all.

11.     If a share certificate is defaced, lost or destroyed it may be replaced
        without fee but on such terms (if any) as to evidence and indemnity and
        to payment of the costs and out of pocket expenses of the Company in
        investigating such evidence and preparing such indemnity as the Board
        may think fit and, in case of defacement, on delivery of the old
        certificate to the Company.

                                     4
<PAGE>

12.     All certificates for share or loan capital or other securities of the
        Company (other than letters of allotment, scrip certificates and other
        like documents) shall, except to the extent that the terms and
        conditions for the time being relating thereto otherwise provide, be
        issued under the Seal. The Board may by resolution determine, either
        generally or in any particular case, that any signatures on any such
        certificates need not be autographic but may be affixed to such
        certificates by some mechanical means or may be printed thereon or that
        such certificates need not be signed by any persons.


                                   LIEN

13.     The Company shall have a first and paramount lien on every share (not
        being a fully paid share) for all moneys, whether presently payable or
        not, called or payable, at a date fixed by or in accordance with the
        terms of issue of such share in respect of such share, and the Company
        shall also have a first and paramount lien on every share (other than a
        fully paid share) standing registered in the name of a Member, whether
        singly or jointly with any other person, for all the debts and
        liabilities of such Member or his estate to the Company, whether the
        same shall have been incurred before or after notice to the Company of
        any interest of any person other than such Member, and whether the time
        for the payment or discharge of the same shall have actually arrived or
        not. and notwithstanding that the same are joint debts or liabilities of
        such Member or his estate and any other person, whether a Member or not.
        The Company's lien on a share shall extend to all dividends payable
        thereon. The Board may at any time, either generally or in any
        particular case, waive any lien that has arisen or declare any share to
        be wholly or in part exempt from the provisions of this Bye-Law.

14.     The Company may sell, in such manner as the Board may think fit, any
        share on which the Company has a lien but no sale shall be made unless
        some sum in respect of which the lien exists is presently payable nor
        until the 'expiration of fourteen days after a notice in writing,
        stating and demanding payment of the sum presently payable and giving
        notice

                                     5
<PAGE>
  of the intention to sell in default of such payment, has been served on
  the holder for the time being of the share.

15.     The net proceeds of sale by the Company of any shares on which it has a
        lien shall be applied in or towards payment or discharge of the debt or
        liability in respect of which the lien exists so far as the same is
        presently payable, and any residue shall (subject to a like lien for
        debts or liabilities not presently payable as existed upon the share
        prior to the sale) be paid to the holder of the share immediately before
        such sale. For giving effect to any such sale the Board may authorise
        some person to transfer the share sold to the purchaser thereof. The
        purchaser shall be registered as the holder of the share and he shall
        not be bound to see to the application of the purchase money, nor shall
        his title to the share be affected by any irregularity or invalidity in
        the proceedings relating to the sale.


                              CALLS ON SHARES

16.     The Board may from time to time make calls upon the Members in respect
        of any moneys unpaid on their shares (whether on account of the par
        value of the shares or by way of premium) and not by the terms of issue
        thereof made payable at a date fixed by or in accordance with such terms
        of issue, and each Member shall (subject to the Company serving upon him
        at least fourteen days notice specifying the time or times and place of
        payment) pay to the Company at the time or times and place so specified
        the amount called on his shares. A call may be revoked or postponed as
        the Board may determine.

17.     A call may be made payable by installments and shall be deemed to have
        been made at the time when the resolution of the Board authorizing the
        call was passed. 

18.     The joint holders of a share shall be jointly and severally liable to
        pay all calls in respect thereof.

19.     If a sum called in respect of the share shall not be paid before or on
        the day appointed for payment thereof the person from whom the sum is
        due shall pay interest on the sum from the day appointed for the payment
        thereof to the time of actual payment at such rate as the


                                     6
<PAGE>
  Board may determine, but the Board shall be at liberty to waive payment
  of such interest wholly or in part.

20.     Any sum which, by the terms of issue of a share, becomes payable on
        allotment or at any date fixed by or in accordance with such terms of
        issue, whether on account of the nominal amount of the share or by way
        of premium, shall for all the purposes of these Bye-Laws be deemed to be
        a call duly made, notified and payable on the date on which, by the
        terms of issue, the same becomes payable and, in case of non-payment,
        all the relevant provisions of these Bye-Laws as to payment of interest,
        forfeiture or otherwise shall apply as if such sum had become payable by
        virtue of a call duly made and notified. 

21.     The Board may on the issue of shares differentiate between the allottees
        or holders as to the amount of calls to be paid and the times of
        payment.


                           FORFEITURE OF SHARES

22.     If a Member fails to pay any call or installment of a call on the day
        appointed for payment thereof, the Board may at any time thereafter
        during such time as any part of such call or installment remains unpaid
        serve a notice on him requiring payment of so much of the call or
        installment as is unpaid, together with any interest which may have
        accrued.

23.     The notice shall name a further day (not being less than 14 days from
        the date of the notice) on or before which, and the place where, the
        payment required by the notice is to be made and shall state that, in
        the event of non-payment on or before the day and at the place
        appointed, the shares in respect of which such call is made or
        installment is payable will be liable to be forfeited. The Board may
        accept the surrender of any share liable to be forfeited hereunder and,
        in such case, references in these Bye-Laws to forfeiture shall include
        surrender.


24.     If the requirements of any such notice as aforesaid are not complied
        with, any share in respect of which such notice has been given may at
        any time thereafter, before payment of all calls or installments and
        interest due in respect thereof has been made, be forfeited by

                                     7
<PAGE>

  a resolution of the Board to that effect.  Such forfeiture shall include
  all dividends declared in respect of the forfeited shares and not
  actually paid before the forfeiture.

25.     When any share has been forfeited, notice of the forfeiture shall be
        served upon the person who was before forfeiture the holder of the
        share; but no forfeiture shall be in any manner invalidated by any
        omission or neglect to give such notice as aforesaid.

26.     A forfeited share shall be deemed to be the property of the Company and
        may be sold, reoffered or otherwise disposed of either to the person who
        was, before forfeiture, the holder thereof or entitled thereto or to any
        other person upon such terms and in such manner as the Board shall think
        fit, and at any time before a sale, re-allotment or disposition the
        forfeiture may be cancelled on such terms as the Board may think fit.

27.     A person whose shares have been forfeited shall thereupon cease to be a
        Member in respect of the forfeited shares but shall, notwithstanding the
        forfeiture, remain liable to pay to the Company all moneys which at the
        date of forfeiture were presently payable by him to the Company in
        respect of the shares with interest thereon at such rate as the Board
        may determine from the date of forfeiture until payment, and the Company
        may enforce payment without being under any obligation to make any
        allowance for the value of the shares forfeited.

28.     An affidavit in writing that the deponent is a Director or the Secretary
        of the Company and that a share has been duly forfeited on the date
        stated in the affidavit shall be conclusive evidence of the facts
        therein stated as against all persons claiming to be entitled to the
        share. The Company may receive the consideration (if any) given for the
        share on the sale, re-allotment or disposition thereof and the Board may
        authorise some person to transfer the share to the person to whom the
        same is sold, re-allotted or disposed of, and he shall thereupon be
        registered as the holder of the share and shall not be bound to see to
        the application of the purchase money (if any) nor shall his title to
        the share be affected by any irregularity or invalidity in the
        proceedings relating to the forfeiture, sale, re-allotment or disposal
        of the share.

               REGISTERS OF MEMBERS, DIRECTORS AND OFFICERS

29.     (a)   The Secretary shall establish and maintain the Register of Members
              at the Registered Office in the manner prescribed by the Companies
              Acts. Unless the Board other-wise determines, the Register of
              Members shall be open to inspection in the manner prescribed by
              the Companies Acts between 10.00 a.m. and 12.00 noon on every
              working day. Subject to the provisions of the Companies Acts, the
              Board may establish Branch Registers of Members in countries in
              which the shares of the Company are dealt on a stock exchange and
              shares of the Company shall be registered on both the Register and
              any such Branch Register. Unless the Board so determines, no
              Member or intending Member shall be entitled to have entered in
              the Register any indication of any trust or any equitable,
              contingent, future or partial interest in any share or any
              interest in any fractional part of a share and if any such entry
              exists or is permitted by the Board it shall not be deemed to
              abrogate any of the provisions of Bye-Law 9.

  (b)   The Secretary shall establish and maintain a register of the
        Directors and Officers of the Company as required by the Companies
        Acts. The Register of Directors and Officers shall be open to
        inspection in the manner prescribed by the Companies Acts between
        10.00 a.m. and 12.00 noon on every working day.


                            TRANSFER OF SHARES

30.     Subject to the Companies Acts and to such of the restrictions contained
        in these Bye-Laws as may be applicable, any Member may transfer all or
        any of his shares by an instrument of transfer in the usual common form
        or in any other form which the Board may approve.

31.     The instrument of transfer of a share shall be signed by or on behalf of
        the transferor and where any share is not fully-paid the transferee, and
        the transferor shall be deemed to remain the holder of the share until
        the name of the transferee is entered in the Register in respect
        thereof.  All instruments of transfer when registered may be retained by
        the

                                     9
<PAGE>
  Company. The Board may, in its absolute discretion and without assigning
  any reason therefor, decline to register any transfer of any share which
  is not a fully-paid share. The Board may also decline to register any
  transfer unless:-

  (a)   the instrument of transfer is duly stamped and lodged with the
        Company, accompanied by the certificate for the shares to which it
        relates, and such other evidence as the Board may reasonably
        require to show the right of the transferor to make the transfer,

  (b)   the instrument of transfer is in respect of only one class of
        share,

  (c)   where applicable, the permission of the Bermuda Monetary Authority
        with respect thereto has been obtained.

  Subject to any directions of the Board from time to time in force, the
  Secretary may exercise the powers and discretions of the Board under
  this Bye-Law and Bye-Laws 30 and 32.

32.     If the Board declines to register a transfer it shall, within three
        months after the date on which the instrument of transfer was lodged,
        send to the transferee notice of such refusal. 

33.     No fee shall be charged by the Company for registering any transfer,
        probate, letters of administration, certificate of death or marriage,
        power of attorney, distringas or stop notice, order of court or other
        instrument relating to or affecting the title to any share, or otherwise
        making an entry in the Register relating to any share.


                          TRANSMISSION OF SHARES

34.     In the case of the death of a Member, the survivor or survivors, where
        the deceased was a joint holder, and the estate representative, where he
        was sole holder, shall be the only person recognised by the Company as
        having any title to his shares; but nothing herein contained shall
        release the estate of a deceased holder (whether the sole or joint) from
        any liability in respect of any share held by him solely or jointly with
        other persons.  For the purpose of this Bye-Law, estate representative
        means the person to whom probate or letters of administration has or
        have been granted in Bermuda or, failing any such person,

                                    10
<PAGE>
  such other person as the Board may in its absolute discretion determine
  to be the person recognised by the Company for the purpose of this
  Bye-Law.


35.     Any person becoming entitled to a share in consequence of the death of a
        Member or otherwise by operation of applicable law may, subject as
        hereafter provided and upon such evidence being produced as may from
        time to time be required by the Board as to his entitlement, either be
        registered himself as the holder of the share or elect to have some
        person nominated by him registered as the transferee thereof. If the
        person so becoming entitled elects to be registered himself, he shall
        deliver or send to the Company a notice in writing signed by him stating
        that he so elects. If he shall elect to have his nominee registered, he
        shall signify his election by signing an instrument of transfer of such
        share in favour of his nominee. All the limitations, restrictions and
        provisions of these Bye-Laws relating to the right to transfer and the
        registration of transfer of shares shall be applicable to any such
        notice or instrument of transfer as aforesaid as if the death of the
        Member or other event giving rise to the transmission had not occurred
        and the notice or instrument of transfer was an instrument of transfer
        signed by such Member.

36.     A person becoming entitled to a share in consequence of the death of a
        Member or otherwise by operation of applicable law shall (upon such
        evidence being produced as may from time to time be required by the
        Board as to his entitlement) be entitled to receive and may give a
        discharge for any dividends or other moneys payable in respect of the
        share, but he shall not be entitled in respect of the share to receive
        notices of or to attend or vote at general meetings of the Company or,
        save as aforesaid, to exercise in respect of the share any of the rights
        or privileges of a Member until he shall have become registered as the
        holder thereof. The Board may at any time give notice requiring such
        person to elect either to be registered himself or to transfer the share
        and if the notice is not complied with within sixty days the Board may
        thereafter withhold payment of all dividends and other moneys payable in
        respect of the shares until the requirements of the notice have been
        complied with.

                                    11

37.     Subject to any directions of the Board from time to time in force, the
        Secretary may exercise the powers and discretions of the Board under
        Bye-Laws 34, 35 and 36.


                            INCREASE OF CAPITAL

38.     The Company may from time to time increase its capital by such sum to be
        divided into shares of such par value as the Company in general meeting
        shall prescribe.

39.     The Company may, by the resolution increasing the capital, direct that
        the new shares or any of them shall be offered in the first instance
        either at par or at a premium or (subject to the provisions of the
        Companies Acts) at a discount to all the holders for the time being of
        shares of any class or classes in proportion to the number of such
        shares held by them respectively or make any other provision as to the
        issue of the new shares.

40.     The new shares shall be subject to all the provisions of these Bye-Laws
        with reference to lien, the payment of calls, forfeiture, transfer,
        transmission and otherwise.


                           ALTERATION OF CAPITAL

41. The Company may from time to time in general meeting;-

  (a)   divide its shares into several classes and attach thereto
        respectively any preferential, deferred, qualified or special
        rights, privileges or conditions; 

  (b)   consolidate and divide all or any of its share capital into shares
        of larger par value than its existing shares; 

  (c)   sub-divide its shares or any of them into shares of smaller par
        value than is fixed by its memorandum, so, however, that in the
        sub-division the proportion between the amount paid and the
        amount, if any, unpaid on each reduced share shall be the same as
        it was in the case of the share from which the reduced share is
        derived; 

  (d)   make provision for the issue and allotment of shares which do not
        carry any voting rights; and

  (e)   cancel shares which, at the date of the passing of the resolution
        in that behalf, have not been taken or agreed to be taken by any
        person, and diminish the amount of its share capital by the amount
        of the shares so canceled.


                                    12
<PAGE>

  Where any difficulty arises in regard to any division, consolidation, or
  sub-division under this Bye-Law, the Board may settle the same as it
  thinks expedient and, in particular, may arrange for the sale of the
  shares representing fractions and the distribution of the net proceeds
  of sale in 'due proportion amongst the Members who would have been
  entitled to the fractions, and for this purpose the Board may authorise
  some person to transfer the shares representing fractions to the
  purchaser thereof, who shall not be bound to see to the application of
  the purchase money nor shall his title to the shares be affected by any
  irregularity or invalidity in the proceedings relating to the sale.

42.     Subject to the Companies Acts and to any confirmation or consent
        required by law or these Bye-Laws, the Company may by resolution in
        general meeting from time to time convert any preference shares into
        redeemable preference shares.


                           REDUCTION OF CAPITAL 

43.     Subject to the Companies Acts, its memorandum and any confirmation or
        consent required by law or these Bye-Laws, the Company may from time to
        time in general meeting authorise the reduction of its issued share
        capital or any capital redemption reserve fund or any share premium or
        contributed surplus account in any manner.

44.     In relation to any such reduction, the Company may in general meeting
        determine the terms upon which such reduction is to be effected
        including in the case of a reduction of part only of a class of shares,
        those shares to be affected.


                             GENERAL MEETINGS

45.     The Board shall convene and the Company shall hold general meetings as
        Annual General Meetings in accordance with the requirements of the
        Companies Acts at such times and places as the Board shall appoint. The
        Board may, whenever it thinks fit, and shall, when required by the
        Companies Acts, convene general meetings other than Annual General
        Meetings which shall be called Special General Meetings.


                                    13
<PAGE>
                        NOTICE OF GENERAL MEETINGS 

46.     An Annual General Meeting shall be called by not less than five (5)
        days' notice in writing and a Special General Meeting shall be called by
        not less than fourteen (14) days' notice in writing. The notice shall be
        exclusive of the day on which it is served or deemed to be served and of
        the day for which it is given, and shall specify the place, day and time
        of the meeting, and, in the case of a Special General Meeting, the
        general nature of the business to be considered. Notice of every general
        meeting shall be given in any manner permitted by Bye-Laws 122 and 123
        to all Members other than such as, under the provisions of these
        Bye-Laws or the terms of issue of the shares they hold, are not entitled
        to receive such notice from the Company.

  Notwithstanding that a meeting of the Company is called by shorter
  notice than that specified in this Bye-Law, it shall be deemed to have
  been duly called if it is so agreed:-

  (a)   in the case of a meeting called as an Annual General Meeting, by
        all the Members entitled to attend and vote thereat;

  (b)   in the case of any other meeting, by a majority in number of the
        Members having the right to attend and vote at the meeting, being
        a majority together holding not less than 95 percent in nominal
        value of the shares giving that right.

47.     The accidental omission to give notice of a meeting or (in cases where
        instruments of proxy are sent out with the notice) the accidental
        omission to send such instrument of proxy to, or the non-receipt of
        notice of a meeting or such instrument of proxy by, any person entitled
        to receive such notice shall not invalidate the proceedings at that
        meeting.

                     PROCEEDINGS AT GENERAL MEETINGS 

48.     No business shall be transacted at any general meeting unless a quorum
        is present when the meeting proceeds to business, but the absence of a
        quorum shall not preclude the appointment, choice or election of a
        chairman which shall not be treated as part of the business of the
        meeting. Save as otherwise provided by these Bye-Laws, at least two

                                    14
<PAGE>
  Members present in person and entitled to vote holding or representing
  at least 5% of the issued share capital of the Company, shall be a
  quorum for all purposes.

49.     If within five minutes (or such longer time as the Chairman of the
        meeting may determine to wait) after the time appointed for the meeting,
        a quorum is not present, the meeting, if convened on the requisition of
        Members, shall be dissolved. In any other case, it shall stand adjourned
        to such other day and such other time and place as the Chairman of the
        meeting may determine and at such adjourned meeting two Members present
        in person (whatever the number of shares held by them) shall be a
        quorum. The Company shall give not less than five (5) days' notice of
        any meeting adjourned through want of a quorum and such notice shall
        state that two Members present in person (whatever the number of shares
        held by them) shall be a quorum.

50.     Each Director shall be entitled to attend and speak at any general
        meeting of the Company.

51.     The Chairman (if any) of the Board or, in his absence, the President
        shall preside as Chairman at every general meeting. If there is no such
        Chairman or President, or if at any meeting neither of the Chairman nor
        the President is present within five minutes after the time appointed
        for holding the meeting, or if neither of them is willing to act as
        Chairman, the Directors present shall choose one of their number to act
        or if one Director only is present he shall preside as Chairman if
        willing to act. If no Director is present or, if each of the Directors
        present declines to take the chair, the persons present and entitled to
        vote on a poll shall elect one of their number to be Chairman.

52.     The Chairman may, with the approval by resolution of any meeting at
        which a quorum is present (and shall if so directed by the meeting),
        adjourn the meeting from time to time and from place to place but no
        business shall be transacted at any .adjourned meeting except business
        which might lawfully have been transacted at the meeting from which the
        adjournment took place. When a meeting is adjourned for three months or
        more, notice of the adjourned meeting shall be given as in the case of
        an original meeting.

                                    15
<PAGE>

53.     Save as expressly provided by these Bye-Laws, it shall not be necessary
        to give any notice of an adjournment or of the business to be transacted
        at an adjourned meeting.


                                  VOTING

54.     Save where a greater majority is required by the Companies Acts or these
        Bye-Laws, any question proposed for consideration at any general meeting
        shall be decided on by a simple majority of votes cast.

55.     Subject and without prejudice to any special fights, privileges or
        restrictions as to voting for the time being attached to any special

        time (being not later than three months after the date of the demand)
        and place as the Chairman shall direct. It shall not be necessary
        (unless the Chairman otherwise directs) for notice to be given of a
        poll.

58.     The demand for a poll shall not prevent the continuance of a meeting for
        the transaction of any business other than the question on which the
        poll has been demanded and it may be withdrawn at any time before the

        tenders a vote, whether in person or by proxy, shall be accepted to the
        exclusion of the votes of the other joint holders, and for this purpose

  proxy, and may otherwise act and be treated as such Member for the
  purpose of general meetings.

        resolution unless the same is raised or pointed out at the meeting or,
        as the case may be, the adjourned meeting at which the vote objected to
        is given or tendered or at which the error occurs. Any objection or
        error shall be referred to the Chairman of the meeting and shall only
        vitiate the decision of the meeting on any resolution if the Chairman
        decides that the same may have affected the decision of the meeting. The
        decision of the Chairman on such matters shall be final and conclusive.

  standing proxy or authorisation exists, its operation shall be deemed to
  have been suspended at any general meeting or adjournment thereof at

  specially appointed a proxy or representative. The Board may from time
  to time require such evidence as it shall deem necessary as to the due
  execution and continuing validity of any such standing proxy or
  authorisation and the operation of any such standing proxy or
  authorisation shall be deemed to be suspended until such time as the
  Board determines that it has received the requested evidence or other
  evidence satisfactory to it.

        amendment of a resolution put to the meeting for which it is given as
        the proxy thinks fit. The instrument of proxy shall unless the contrary

        officer of, or employed by, or a party to any transaction or
        arrangement with, or otherwise interested in, any body corporate

        or arrangement so made.

              Director shall not vote in respect of any contract or arrangement

        to the Chairman of the meeting and his ruling in relation to any
        other Director shall be final and conclusive, except in a case

        Members according to their rights and interests in the profits including
        such interim dividends as appear to the Board] to be justified by the
        position of the Company. The Board may also pay any fixed cash dividend
        which is payable on any shares of the Company half yearly or on such
        other dates, whenever the position of the Company, in the opinion of the
        Board, justifies such payment. For the purpose of this Bye-Law,
        contributed surplus shall be deemed not to be a profit of the Company
        and shall not be taken account of in calculating the amount of the
        profits available for distribution to the Members and shall not be
        available for distribution other than in the manner provided for in
        Bye-Law 110.

107.    Except insofar as the rights attaching to, or the terms of issue of, any
        share otherwise provide:-

  (a)   all dividends may be declared and paid according to the amounts
        paid up on the shares in respect of which the dividend is paid,
        and an amount paid up on a share in advance of calls may be
        treated for the purpose of this Bye-Law as paid-up on the share;

  (b)   dividends may be apportioned and paid pro rata according to the
        amounts paid-up on the shares during any portion or portions of
        the period in respect of which the dividend is paid.

108.    The Board may deduct from any dividend or other moneys payable to a
        Member by the Company on or in respect of any shares all sums of money
        (if any) presently payable by him to the Company on account of calls or
        otherwise in respect of shares of the Company.

109.    No dividend or other moneys payable by the Company on or in respect of
        any share shall bear interest against the Company.

110.    Any dividend, interest or other sum payable in cash to the holder of
        shares may be paid by cheque or warrant sent through the post addressed
        to the holder at his address in the Register or, in the case of joint
        holders, addressed to the holder whose name stands first



                                    34

<PAGE>

  in the Register in respect of the shares at his registered address as
  appearing in the register or addressed to such person at such address as
  the holder or joint holders may in writing direct. Every such cheque or
  warrant shall, unless the holder or joint holders otherwise direct, be
  made payable to the order of the holder or, in the case of joint
  holders, to the order of the holder whose name stands first in the
  Register in respect of such shares, and shall be sent at his or their
  risk and payment of the cheque or warrant by the bank on which it is
  drawn shall constitute a good discharge to the Company. Any one of two
  or more joint holders may give effectual receipts for any dividends or
  other moneys payable or property distributable in respect of the shares
  held by such joint holders.

111.    Any dividend unclaimed for a period of six years from the date of
        declaration of such dividend shall be forfeited and shall revert to the
        Company and the payment by the Board of any unclaimed dividend, interest
        or other sum payable on or in respect of the share into a separate
        account shall not constitute the Company a trustee in respect thereof.

112.    With the sanction of the Company in general meeting, the Board may (a)
        declare a distribution to any Member out of contributed surplus and (b)
        may direct payment or satisfaction of such distribution or any dividend
        wholly or in part by the distribution of specific assets, and in
        particular of paid-up shares or debentures of any other company, and
        where any difficulty arises in regard to such distribution or dividend
        the Board may settle it as it thinks expedient, and in particular, may
        authorise any person to sell and transfer any fractions or may ignore
        fractions altogether, and may fix the value for distribution or dividend
        purposes of any such specific assets and may determine that cash
        payments shall be made to any Members upon the footing of the values so
        fixed in order to secure equality of distribution and may vest any such
        specific assets in trustees as may seem expedient to the Board.


                                 RESERVES

113.    The Board may, before recommending or declaring any dividend, set aside
        out of the profits of the Company such sums as it thinks proper as
        reserves which shall, at the


                                    35
<PAGE>

  discretion of the Board, be applicable for any purpose to which the
  profits of the Company may be properly applied and pending such
  application may, also at such discretion, either be employed in the
  business of the Company or be invested in such investments as the Board
  may from time to time think fit. The Board may also without placing the
  same to reserve carry forward any profits which it may think it prudent
  not to distribute.


                         CAPITALIZATION OF PROFITS

114.    The Company may, upon the recommendation of the Board, at any time and
        from time to time resolve in general meeting to the effect that it is
        desirable to capitalize all or any part of any amount for the time being
        standing to the credit of any reserve or fund which is available for
        distribution or to the credit of any share premium account or any
        capital redemption reserve fund and accordingly that such amount be set
        free for distribution amongst the Members or any class of Members who
        would be entitled thereto if distributed by way of dividend and in the
        same proportions, on the footing that the same be not paid in cash but
        be applied either in or towards paying up amounts for the time being
        unpaid on any shares in the Company held by such Members respectively or
        in payment up in full of unissued shares, debentures or other
        obligations of the Company, to be allotted and distributed credited as
        fully paid amongst such Members, or partly in one way and partly in the
        other, and the Board shall give effect to such resolution, provided that
        for the purpose of this Bye-Law, a share premium account and a capital
        redemption reserve fund may be applied only in paying up of unissued
        shares to be issued to such Members credited as fully paid.

115.    Where any difficulty arises in regard to any distribution under the last
        preceding Bye-Law the Board may settle the same as it thinks expedient
        and, in particular, may authorise any person to sell and transfer any
        fractions or may resolve that the distribution should be as nearly as
        may be practicable in the correct proportion but not exactly so or may
        ignore fractions altogether, and may determine that cash payments should
        be made to any


                                    36
<PAGE>

  Members in order to adjust the rights of all parties, as may seem
  expedient to the Board. The Board may appoint any person to sign on
  behalf of the persons entitled to participate in the distribution any
  contract necessary. or desirable for giving effect thereto and such
  appointment shall be effective and binding upon the Members.


                               RECORD DATES

116.    Notwithstanding any other provisions of these Bye-Laws the Company in
        general meeting or the Board may fix any date as the record date for any
        dividend, distribution, allotment or issue and for the purpose of
        identifying the persons entitled to receive notices of general meetings.
        Any such record date may be on or at any time before or after any date
        on which such dividend, distribution, allotment or issue is declared,
        paid or made or such notice is despatched.

        other place or places as the Board thinks fit, and shall at all times be
        open to inspection by the Directors: PROVIDED that if the records of
        account are kept at some place outside Bermuda, there shall be kept at
        an office of the Company in Bermuda such records as will enable the
        directors to ascertain with reasonable accuracy the financial position
        of the Company at the end of each three month period. No Member (other
        than an officer of the Company) shall have any right to inspect any
        accounting record or book or document of the Company except as conferred
        by law or authorised by the Board or the Company in general meeting.

        by the Companies Acts, auditors shall be appointed and their duties
        regulated in accordance with the Companies Acts, any other applicable
        law and such requirements not inconsistent with the Companies Acts as
        the Board may from time to time determine.

        served on or delivered to any Member by the Company either personally or

        pre-paid letter addressed to such Member at his address as appearing in
        the Register or by delivering it to or leaving it at such registered
        address. In the case of joint holders of a share, service or delivery of
        any notice or other document on or to one of the joint holders shall for
        all purposes be deemed as sufficient service on or delivery to all the
        joint holders. Any notice or other document if sent by post shall be
        deemed to have been served or delivered seven days after it was put in
        the post, and in proving such service or delivery, it shall be
        sufficient to prove that the notice or document was properly addressed,
        stamped and put in the post.

122.    Any notice of a general meeting of the Company shall be deemed to be
        duly given to a Member if it is sent to him by cable, telex, telecopier
        or other mode of representing or reproducing words in a legible and
        non-transitory form at his address as appearing in the Register or any
        other address given by him to the Company for this purpose. Any such
        notice shall be deemed to have been served twenty-four hours after its
        dispatch.


123.    Any notice or other document delivered, sent or given to a Member in any
        manner permitted by these Bye-Laws shall, notwithstanding that such
        Member is then dead or bankrupt or that any other event has occurred,
        and whether or not the Company has notice of the death or bankruptcy or
        other event, be deemed to have been duly served or


                                    38
<PAGE>

  delivered in respect of any share registered in the name of such Member
  as sole or joint holder unless his name shall, at the time of the
  service or delivery of the notice or document, have been removed from
  the Register as the holder of the share, and such service or delivery'
  shall for all purposes be deemed as sufficient service or delivery of
  such notice or document on all persons interested (whether jointly with
  or as claiming through or under him) in the share.


                                WINDING UP

124.    If the Company shall be wound up, the liquidator may, with the sanction
        of a resolution of the Company and any other sanction required by the
        Companies Acts, divide amongst the Members in specie or kind the whole
        or any part of the assets of the Company (whether they shall consist of
        property of the same kind or not) and may for such purposes set such
        values as he deems fair upon any property to be divided as aforesaid and
        may determine how such division shall be carried out as between the
        Members or different classes of Members. The liquidator may, with the
        like sanction, vest the whole or any part of such assets in trustees
        upon such trust for the benefit of the contributories as the liquidator,
        with the like sanction, shall think fit, but so that no Member shall be
        compelled to accept any shares or other assets upon which there is any
        liability.


                                 INDEMNITY

125.    Subject to the proviso below, every Director, officer of the Company and
        member of a committee constituted under Bye-Law 93 shall be indemnified
        out of the funds of the Company against all civil liabilities loss

        member and the indemnity contained in this Bye-Law shall extend to any
        person acting as a Director, officer or committee member in the
        reasonable belief that he has been so appointed or elected

                                    39

  contained in this Bye-Law shall not extend to any matter which would
  render it void pursuant to the Companies Acts.

        Bye-Law 93 of the Company shall be indemnified out of the funds of the
        Company against all liabilities incurred by him as such Director,
        officer or committee member in defending any proceedings, whether civil
        or criminal, in which judgment is given in his favour, or in which he is
        acquitted, or in connection with any application under the Companies
        Acts in which relief from liability is granted to him by the court.

127.    To the extent that any Director, officer or member of a committee duly
        constituted under Bye-Law 93 is entitled to claim an indemnity pursuant
        to these Bye-Laws in respect of amounts paid or discharged by him, the
        relative indemnity shall take effect as an obligation of the Company to
        reimburse the person making such payment or effecting such discharge.



                          ALTERATION OF BYE-LAWS
128.    These Bye-Laws may be amended from time to time in the manner provided
        for in the Companies Acts.

                         INDEMNIFICATION AGREEMENT

  This Agreement dated February 1, 1994 by and between MERCURY
ACQUISITIONS INC., a Nevada corporation to be renamed VISTA TECHNOLOGIES INC.
(the "Company") and MURRAY D. WATSON (the "Indemnified Party").

  WHEREAS,  the  Indemnified  Party  has  and/or  will  act  as  a 
director,  officer,  employee, financial advisor and/or agent of the Company;
and

  WHEREAS, in consideration of such services, and pursuant to authority of
its Board of Directors, the Company has agreed to enter into this Agreement;

  NOW, THEREFORE, the parties hereto agree as follows:

  1.    The Company hereby agrees to indemnify and hold harmless the
Indemnified Party against any and all losses, claims, damages, judgments,
liabilities or costs, including related attorneys'  fees and other costs of
investigation, preparation, defense and providing evidence, whether or not in
connection with litigation in which the Indemnified Party is a party, as and
when such losses, claims, damages, judgments,  liabilities or costs are
incurred, which are directly or indirectly caused by, relating to, based upon
or arising out of any act or omission on the part of the Indemnified Party in
his or her capacity as a director, officer, employee, financial advisor or
agent of the Company or in connection with any transactions undertaken as a
result of such relationship, including any actions taken or decisions made as
a director, officer, employee, financial advisor or agent with respect
thereto.  Furthermore, the Company waives its right to bring any claim against
the Indemnified Party in connection with any matter caused by, relating to,
based upon or arising out of any act or omission on the part of the
Indemnified Party in his or her capacity as a director, officer, employee,
financial  advisor or agent of the Company or in connection with any
transactions undertaken as  a result of such relationship, other than any
actions based on the gross negligence or willful misconduct of the Indemnified
Party.

  2.    The Indemnified Party shall promptly notify the Company in writing
of any action or proceeding (including any governmental investigation) brought
or asserted against the Indemnified Party in respect of which indemnity is
sought from the Company hereunder, and (subject to clause (c) below) the
Company shall promptly assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of
all fees and expenses incurred in connection with the defense thereof.  The
Indemnified Party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof if (a) the Indemnified  Party
shall pay the fees and expenses of such separate counsel or (b) the Company
shall have failed promptly to assume the defense of such action or proceeding
through counsel reasonably satisfactory to the Indemnified Party or (c) the
named parties to any such action or proceeding (including any impleaded
parties) include both the Indemnified Party and the Company and the
Indemnified Party shall have been advised in writing by counsel that there
maybe one or more legal defenses available to the Indemnified Party which are
different from or additional to those available to the Company, in which case 
the Indemnified Party may elect in writing to employ separate counsel at the
expense of the Company (after which the Company shall not

<PAGE>

have the right to defense of such action or proceeding on behalf of such
Indemnified Party), it being understood, however, that the Company shall not,
in connection with any one such action or proceeding or separate but
substantially similar or related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys
(together with appropriate local counsel) at any time, which firm shall be
designated by agreement of all indemnified parties and, if no agreement is
reached by the indemnified parties within 15 days of the filing of the 
relevant complaint, by the Company.  The Company shall not be liable for any
settlement of any such action or proceeding effected without its written
consent (which shall not be unreasonably withheld), but if any such action or
proceeding is settled with its written  consent, the Company agrees to
indemnify and hold harmless the Indemnified Party from and against any loss,
claim, damage, or liability (to the extent stated above) by reason of such
settlement or judgment.

  3.    In order to provide for just and equitable contribution, if a
claim for indemnification hereunder is found unenforceable in a final judgment
by a court of competent jurisdiction (not subject to further appeal), even
though the express  provisions hereof provide for indemnification in such
case, then the Company shall contribute to the losses, claims, damages,
judgments, liability or costs to which the Indemnified Parties may be subject
in accordance with the relative benefits received by, and the relative fault
of, the Company in connection with the statements, acts or omissions which
resulted in such losses, claims, damages, judgments, liabilities, or costs.

  4.    These indemnification provisions shall (i) remain operative and in
full force and effect regardless of any termination of the relationship
between the Company and the Indemnified Party; (ii) inure to the benefit of
any successors, assigns, heirs or personal representative of the Indemnified
Party; and (iii) be in addition to any other rights that the Indemnified Party
may have.

  IN WITNESS WHEREAS, this Agreement has been executed by the parties
hereto on the date first written above.

3.      OTHER REPRESENTATIONS AND WARRANTIES OF THE FOREIGN INVESTOR.   In
connection with this Agreement and the transactions contemplated herein, the
Foreign Investor represents and warrants to PHARMA PATCH as follows:

  3.1.  The Foreign Investor has been duly formed and is validly existing
as a corporation or other legal entity in good standing under the laws of its
jurisdiction of incorporation set forth on the signature page to this
Agreement.  The Foreign Investor is not organized under the laws of the United
States, is not a "U.S. Person" as that term is defined in Rule 902(o) of
Regulation S, and is not an "affiliate" of PHARMA PATCH as that term is used
in regulations promulgated under the Securities Act or associated with any
individual or entity which may be deemed an "affiliate" of PHARMA PATCH as of
the date hereof.  Neither the Foreign Investor, nor any person affiliated with
it, is or has been for the past three months, an officer, director,
controlling shareholder or otherwise in a position to control, select or
influence the management and policies of PHARMA PATCH.

  3.2.  The Foreign Investor was not formed for the purpose of investing
in Regulation S securities or formed for the purpose of investing in this
Agreement and the ADS securities of PHARMA PATCH.  The Foreign Investor is not
registered as an issuer under the Securities Act and is not required to be
registered with the U.S. Securities and Exchange Commission under the
Investment Company Act of 1940, as amended.  The Foreign Investor is entering
into this Agreement and is participating in the Offering for its own account,
and not on behalf of any U.S. Person as defined in Rule 902(o) of Regulation
S.

  3.3.  No offer to enter into this Agreement has been made by PHARMA
PATCH to the Foreign Investor in the United States other than as permitted in
the case of an account managed by a professional fiduciary resident in the
United States within the meaning of Section 902(o)(2) of Regulation S.  At the
times of the offer and execution of this Agreement and, to the best knowledge
of the Foreign Investor, at the time the Offering originated, the Foreign
Investor was located and resident outside the United States other than as
permitted in the case of an account managed by a professional fiduciary
resident in the United States within the meaning of Section 902(o)(2) of
Regulation S.

  3.4.  Neither the Foreign Investor, nor any of its affiliates nor any
person acting on its behalf or any behalf of any such affiliate, has engaged,
or will engage, in any activity undertaken for the purpose of, or that could
reasonable be expected to have the effect of, conditioning the markets in the
United States for the ADS securities or for any securities that are
convertible into or exercisable for ADS securities of PHARMA PATCH, including
but not limited to effecting any sale of PHARMA PATCH securities to or through
the Foreign Investor or any of its affiliates prior to the expiration of any
restricted period contained in Regulation S (any such activity being defined
herein as a "Directed Selling Effort").  To the best knowledge of the
undersigned, this Agreement and the transactions contemplated herein are not
part of a plan or scheme to evade the registration provisions of the
Securities Act and the ADS securities are being purchased for investment
purposes by the Foreign Investor.  The Foreign Investor, and to the best
knowledge of the Foreign Investor, each distributor, if any, participating in
this Offering of PHARMA PATCH ADS securities, has agreed that all offers and
sales of any securities included in the Offering prior to the date hereof and
through the expiration of the any restricted period set forth in Rule 903 of
Regulation S (and as the same may be amended from time to time hereafter)
shall not be made to U.S. Persons or for the account or benefit of U.S.
Persons, and shall otherwise be made in compliance with the provisions of
Regulation S and any other applicable provisions of the Securities Act.  The
Foreign Investor and its representatives have not conducted any Directed
Selling Effort as that term is used and defined in Rule 902 of Regulation S
and will not engage in any such Directed Selling Effort within the United
States through the expiration of any restricted period set forth in Rule 903
of Regulation S.

<PAGE>
  3.5.  The Foreign Investor acknowledges and agrees that following the
expiration of any restricted period provided by Rule 903 of Regulation S, any
interest in this Agreement or in the ADS securities subscribed to hereunder
may be resold within the jurisdiction of the United States or to U.S. Persons
[as defined in Rule 902(o) of Regulation S] by or for the account of the
parties hereto only:  (i) pursuant to a registration statement under the
Securities Act, or (ii) pursuant to an exemption from such registration for
sales by a person other than an issuer, underwriter or dealer as those terms
are used in Section 4(1) and related provisions of the Securities Act and
regulations thereunder, or pursuant to another exemption from registration,
and following the expiration of any restricted period required by Regulation
S.  The Foreign Investor acknowledges that this Agreement and the PHARMA PATCH
ADS securities have not been registered under the Securities Act or qualified
under state securities laws of the United States, and that the transferability
hereof and thereof within the jurisdiction of the United States is restricted
by the Securities Act as well as such state laws.  The Foreign Investor
acknowledges that this Agreement and the ADS securities are being sold in
reliance upon the transaction exemption afforded by Regulation S in connection
with an offshore offer and sale of securities of PHARMA PATCH not within or
subject to the jurisdiction of the United States markets.  The Foreign
Investor acknowledges it has received a copy of Regulation S, is familiar with
and understands the terms thereof, and has had the opportunity to consult with
its legal counsel concerning this Agreement and Regulation S.

The Foreign Investor acknowledges that if any transfer of the ADS securities
is to be made in reliance upon an exemption under the Securities Act, the
issuer of the securities being so transferred or its successor-in-interest may
require an opinion of counsel satisfactory to the issuer that such transfer
may be made pursuant to an applicable exemption under the Securities Act.  The
Foreign Investor acknowledges that, so long as appropriate, a legend similar
to the following may appear on the certificates representing the PHARMA PATCH
ADS securities subscribed for hereunder:  "These securities have not been
registered under the Securities Act of 1933 and may be reoffered and sold only
if registered or if an exemption from such registration is available in the
opinion of counsel satisfactory to the issuer."

  3.6.  The Foreign Investor has not received any general solicitation or
advertising regarding the Offering or this Agreement.   The Foreign Investor
has sufficient knowledge and experience in financial and business matters so
that it is able to evaluate the merits and risks of the Offering and this
Agreement.  The Foreign Investor has had substantial experience in previous
private and public purchases of speculative and restricted securities,
understands that an investment in the ADS securities of PHARMA PATCH is
speculative, and can afford to sustain a complete loss of its investment.

  3.7.  The Foreign Investor has carefully read and reviewed this
Agreement and any other written information received by the Foreign Investor
or its representatives and agent relating to this Offering.  The Foreign
Investor has had an opportunity to ask questions of, and to receive answers
from, one or more of the executive officers of PHARMA PATCH as the Foreign
Investor deems necessary in order for the Foreign Investor to make an informed
decision with respect to this Agreement and the Offering.  The undersigned
Foreign Investor has received complete and satisfactory answers to all such
inquiries.  The undersigned has not received oral or written representations
or assurances from PHARMA PATCH or any representatives of PHARMA PATCH, other
than as set forth in this Agreement.

  3.8.  This Agreement has been duly authorized, executed and delivered by
the Foreign Investor and is a valid and binding agreement enforceable in
accordance with its terms, subject only to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general application
to or affecting creditors' rights generally and to general principles of
equity.  The Foreign Investor has full power and authority necessary to enter
into this Agreement and to perform its obligations hereunder.

<PAGE>
  3.9.  The execution and delivery of this Agreement, and the consummation
of the transactions contemplated herein, do not and will not conflict with or
result in a breach by the Foreign Investor of any of the terms or provisions
of, or constitute a default under, its charter documents, its memorandum or
articles of association or incorporation, its by-laws, any action of its
directors or shareholders, or any indenture, mortgage, deed of trust or other
agreement or instrument to which the undersigned is a party or by which it or
any of its properties or assets are bound, or any existing applicable law,
rule or regulation or any applicable decree, judgment or order of any court,
regulatory body, administrative agency or other governmental body having
jurisdiction over the undersigned or any of its properties or assets.

hereof, each ADS representing  one Ordinary Share, IR Pound .01 par value, in

  The subscription price for each ADS shall be (i) $0.50 per ADS in United
States funds, payable in cash upon acceptance hereof, and (ii) the delivery in
proper form, endorsed for transfer, of one (1) Class C Warrant previously

  2.    DESCRIPTION OF OFFERING.

  2.1.  THE OFFERING.    PHARMA PATCH is offering up to a maximum of
250,000 American Depositary Shares representing up to a maximum of 250,000
Ordinary Shares of PHARMA PATCH on a "best efforts" basis to a limited number
of qualified United States investors in a private placement offering of
securities exempt from the registration requirements of the United States
Securities Act of 1933, as amended (the "Securities Act").   The offering of
such ADS securities to investors who are residents or citizens of the United
States will be made pursuant to Regulation D promulgated under the Securities
Act and is herein called the "Offering".  All of the ADS securities are being
offered at a price of $0.50 per ADS share in U.S. funds and the surrender for
cancellation of one (1) PHARMA PATCH Class C Warrant for each ADS sold in the

proposed future plan of operation and proposed reorganization of PHARMA PATCH. 
There are no minimum amount of subscriptions required in order for PHARMA
PATCH to accept any subscriptions to the Offering.  The Offering will
terminate on February 29, 1996 unless extended at the option of PHARMA PATCH
for an additional period of not more than 15 days.  PHARMA PATCH reserves the
right to terminate the Offering at any time, whether or not the maximum ADS
securities have been sold.

  2.2.  CLASS A WARRANTS TO BE SURRENDERED FOR CANCELLATION.   Each Class
C Warrant to be transferred and surrendered for cancellation by PHARMA PATCH
pursuant to this Offering represents the right to purchase, for $10.00, a unit
of PHARMA PATCH securities consisting of one ADS, one-half of a Class A
Warrant and one-quarter of a Class B Warrant in PHARMA PATCH.  Upon the
acceptance of his, her or its subscription to this Offering, the undersigned
Investor acknowledges that he, she or it is surrendering all rights
represented by such Class C Warrants and the other securities underlying the
Class

<PAGE>
C Warrants.  In order to perform his, her or its obligations under this
Agreement with respect to the transfer and surrender of Class C Warrants, the
Investor represents and warrants to PHARMA PATCH as follows:

(a)     The Investor is the owner of record and beneficially of a sufficient
        number of Class C Warrants, free and clear of any liens, encumbrances or
        other adverse claims, necessary to subscribe for the number of ADS
        securities indicated on the signature page of this Agreement, and the
        Investor has not sold, assigned, endorsed, transferred, deposited under
        any agreement, hypothecated, pawned, pledged for any bank or brokerage
        loan, or otherwise transferred any interest in such Class C Warrants to
        any third party;

(b)     Upon the tender of this subscription Agreement, the Investor shall
        promptly

  (i)   cause certificates representing the Class C Warrants transferred
        and surrendered in connection with this Offering to be delivered
        to, and deposited with, PHARMA PATCH at its offices at 15-16
        FitzWilliam Place, Dublin 2, Ireland; 

  (ii)  deliver to PHARMA PATCH at said office in Dublin, Ireland a stock
        power in the form attached hereto, duly endorsed for transfer of
        said Class C Warrants to PHARMA PATCH with signature guaranteed by
        a medallion signature guaranty;

  (iii) if the Investor is a corporation, partnership or another entity
        (other than an individual), deliver to PHARMA PATCH at said office
        in Dublin, Ireland a certificate in the form attached hereto
        confirming the authority of the officer, general partner or other
        agent executing the aforesaid stock power on behalf of the
        Investor.

The Investor agrees that it will, at any time and from time to time after this
subscription is accepted by PHARMA PATCH, do, execute, acknowledge and
deliver, or will cause to be done, executed, acknowledged and delivered, all
such further acts, assignments, transfers, powers and assurances as may be
required to enable PHARMA PATCH to cancel the Class C Warrants delivered in
payment of the applicable portion of the subscription price to ADS in this
Offering and hereby appoints PHARMA PATCH as the duly authorized agent and
attorney-in-fact of the Investor to cause such Class C Warrants to be
cancelled.

  2.3.  SECURITIES ACT RESTRICTIONS.   The Investor acknowledges that the
ADS securities included in the Offering have not been registered under the
Securities Act or qualified under applicable state securities laws and that
the transferability thereof is restricted by the registration provisions of
the Securities Act as well as such state laws.  Based upon the representations
and agreements being made by the Investor herein, the ADS securities are being
offered and sold pursuant to an exemption from such registration provided by
Sections 4(2) and/or Regulation D promulgated under Section 3(b) of the
Securities Act and applicable state securities law qualification exemptions.

respect to this Agreement or the transactions contemplated hereby.

  3.    REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

  By its acceptance of the subscription from the Investor hereunder,
PHARMA PATCH represents and warrants to the Investor as follows:

  3.1.   PHARMA PATCH is duly organized and validly existing in good
standing as a public limited company under the laws of the Republic of Ireland
with corporate power to enter into this Agreement and to conduct its business
as presently conducted.

  3.2.   PHARMA PATCH is a reporting foreign issuer under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and will cause all the
materials required to be filed by it pursuant to Section 13(a) of the Exchange
Act to be filed with the Securities and Exchange Commission so long as PHARMA
PATCH remains a reporting foreign issuer under the Exchange Act.  PHARMA PATCH
has filed all materials, reports and documents required to be filed pursuant
to Section 13(a) of the Exchange Act for a period of at least twelve months
preceding the date of this Offering (or for such shorter period as it may have
been required to filed such materials).  PHARMA PATCH has made available to
the Investor copies of PHARMA PATCH's filings with the Securities and Exchange
Commission for the last twelve months prior to the date of this Offering
including, without limitation, its last proxy statement to shareholders for
its annual general meeting of shareholders and audited financial statements
for its last fiscal year and unaudited interim financial statements for
periods subsequent thereto.

  3.3.  The ADS securities purchased hereunder, when issued and delivered
upon receipt of the subscription price, will be duly and validly authorized
and issued, fully paid and nonassessable securities of PHARMA PATCH and will
not subject the holders thereof to personal liability by reason of being such
holders.

  3.4.   This Agreement, upon its acceptance by PHARMA PATCH, has been
duly authorized, executed and delivered by PHARMA PATCH and is a valid and
binding agreement enforceable in accordance with its terms.  PHARMA PATCH has
full power and authority necessary to enter into this Agreement and to perform
its obligations hereunder.

  3.5.   The execution and delivery of this Agreement, and the
consummation of the transactions contemplated herein, do not and will not
conflict with or result in a breach by PHARMA PATCH of any of the terms or
provisions of, or constitute a default under, its charter documents, its by-
laws, any action of its directors or stockholders, or any indenture, mortgage,
deed of trust or other agreement or instrument to which it is a party or by
which it or any of its properties or assets are bound, or any existing
applicable law, rule or regulation or any applicable decree, judgment or order
of any court, regulatory body, administrative agency or other governmental
body having jurisdiction over the undersigned or any of its properties or
assets.

  4.    REPRESENTATIONS AND WARRANTIES OF THE INVESTOR.   In connection
with this Agreement and the transactions contemplated herein, the Investor
represents and warrants to PHARMA PATCH as follows:

  4.1.  The Investor has relied only on the information contained in this
Agreement and only such other information (if any) that has been provided in
writing by duly authorized representatives of PHARMA PATCH to the Investor. 
The Investor has carefully read and reviewed this Agreement and any other
documentation provided in connection with this Offering, and has asked such
questions of management of



Regulation D Subscription Agreement                             -3-
<PAGE>
PHARMA PATCH and received from them such information as he or she deems
necessary in order for the Investor to make an informed decision with respect
to an investment in the ADS securities of PHARMA PATCH's Common Stock.  Except
as provided in this Agreement, the Investor warrants that no other
representations, statements or inducements were made to the Investor to
purchase the ADS securities.  The Investor acknowledges that any projections
included in information furnished to the Investor are confidential and are
based upon certain assumptions as to future sales, expenses, operations,
available capital and other assets of PHARMA PATCH and its affiliates, and
there can be no guarantee or assurance that PHARMA PATCH's future operations
will attain the levels included in any such projections.

  4.2.  The Investor has sufficient knowledge and experience of financial
and business matters so that he or she is able to evaluate the relative merits
and risks of purchasing the ADS securities.  The Investor has not received any
general solicitation or advertising regarding this Offering.  The Investor is
aware that an investment in the ADS securities is a speculative investment, is
not liquid, and involves a high degree of risk of loss.  The Investor further
understands and agrees that the securities may be sold only if they are
subsequently registered under the Securities Act and qualified under any
applicable state securities laws or, in the opinion of counsel satisfactory to
PHARMA PATCH, an exemption from such registration and qualification is
available.  The Investor understands that the transfer of the ADS securities
will be prohibited absent full compliance with the Securities Act and all
applicable state securities laws.  The Investor agrees that the certificates
representing the ADS securities will bear legends indicating that subsequent
transfer of these securities is restricted by reason of the fact that they
have not been registered or qualified under federal securities laws.

  4.3.  The Investor's commitment in direct participation in investments
in restricted securities is reasonable in relation to his or her net worth. 
The investment of the Investor in the ADS securities will in no event exceed
10% of the net worth of the Investor.  The Investor has the means to provide
for his or her personal needs, possesses the ability to bear the economic risk
hereunder indefinitely, and can afford a complete loss of his or her
investment.

  4.4   The Investor is acquiring the ADS securities for his or her own
account only, for long-term investment and not with a view toward resale or
distribution thereof.  The Investor realizes that the ADS securities must not
be purchased unless the Investor has liquid assets sufficient to assure that
this investment will cause no undue financial difficulties and the Investor
can provide for current financial needs and possible personal contingencies
from other funds.  

  4.5.  All information which the Investor has provided to PHARMA PATCH or
its representatives concerning the Investor's financial position and knowledge
of investment matters is correct and complete as of the date set forth herein. 
If the Investor is an "accredited investor" within the meaning of Regulation D
under the Securities Act, the undersigned has reviewed carefully the
definition of Investor set forth in Exhibit B attached hereto and is an
"accredited investor" within that definition.  The Investor understands that
PHARMA PATCH cannot determine whether it will be in a position to accept this
subscription before reviewing suitability information supplied by the
Investor.

  4.6.  The Investor acknowledges that PHARMA PATCH has offered to make
available, prior to this subscription, to each prospective investor, the
opportunity to ask questions of, and receive written answers from, authorized
representatives of PHARMA PATCH concerning the terms and conditions of this
Offering, the existing and proposed operations of PHARMA PATCH, and any other



Regulation D Subscription Agreement                             -4-
<PAGE>
relevant matters, and to obtain any additional written information, to the
extent that PHARMA PATCH possesses such information or can acquire it without
unreasonable effort or expense, necessary to verify the accuracy of any
information provided in connection with the Offering.

  4.7.  This Agreement has been duly authorized, executed and delivered by
the Investor and is a valid and binding agreement enforceable in accordance
with its terms.  The Investor has full power and authority necessary to enter
into this Agreement and to perform his or her obligations hereunder.

  5.    OTHER PROVISIONS.

  5.1.  Each of the parties understand that no governmental agency of any
jurisdiction has passed upon or made any recommendation or endorsement of the
ADS securities, the transactions contemplated by this Agreement, or an
investment in the ADS securities.

  5.2   This Subscription Agreement may be executed in one or more
counterparts and transmitted by facsimile telephonic transmission, each of
which shall be deemed to constitute an original and shall become effective
when one or more counterparts have been signed by each of the parties hereto
and delivered or transmitted by facsimile telephonic transmission to the other
party.

  5.3   Each of the undersigned agrees to pay its own expenses incident to
the performance of its obligations hereunder.

  5.4   Each of the undersigned agree this Agreement shall be governed by
and construed in accordance with the laws of the Republic of Ireland, and
without regard to principles of conflicts of law.

  5.5   The headings of the sections of this Agreement have been inserted
for convenience of reference only, and shall not be deemed to be a part of
this Agreement.

  5.6   Time shall be of the essence of this Agreement.

the holder of record of this Note (which notice may be waived in writing by

prepayment redemption and prepay all or any portion of the principal of this
Note at the time outstanding (except to the extent this Note has been
converted into the Company's common stock in accordance with Section 4 of this

redemption and prepaid prior to the Maturity Date, at one hundred and ten
percent (110%) of the principal amount so being prepaid plus all unpaid

covenants and agrees that upon any partial prepayment of this Note, and upon
the request of the Company, this Note shall be made available to the Company
for notation hereon of the payment of the portion of the principal so prepaid,
in which case the Company shall make such notation and return this Note to or
on the order of the holder of this Note.

  4.    CONVERSION RIGHTS.

  4.1.  CERTAIN DEFINITIONS.  The following terms used in this Note shall
be defined as follows:

  "Company Common Stock" shall mean the common stock of the Company as
such common stock was constituted on May 31, 1995, and as the same shall be
constituted thereafter including appropriate and equitable adjustment for any
capital reorganization or reclassification thereof.

  "Conversion Price" shall mean, subject to possible adjustment in
accordance with the provisions of Section 4.2 of this Note, the amount of ONE
DOLLAR ($1.00) per share of Company Common Stock.

  4.2.  CERTAIN ADJUSTMENTS AND NOTICES RELATING TO THE CONVERSION PRICE
AND COMPANY COMMON STOCK.   The Conversion Price and number of shares of
Company Common Stock issuable upon conversion of this Note shall be subject to
adjustment from time to time hereafter as follows:

        (A)   In case the Company at any time after May 31, 1995 shall
issue a stock dividend on its outstanding shares of Company Common Stock or
shall subdivide or combine the outstanding shares of Company Common Stock into
a greater or lesser number of shares, the Conversion Price and number of
shares issuable upon conversion of the this Note shall be proportionately and
equitably adjusted as if the holder of record of this Note had converted this
Note into Company Common Stock immediately prior to such event.  Any such
adjustment shall become effective at the close of business on the date that
such stock dividend, subdivision or combination relating to the Company Common
Stock shall become effective.  For the purposes of such adjustment, the
Conversion Price in effect immediately prior to such stock dividend,
subdivision or combination shall forthwith be changed to a Conversion Price
determined by:


                                    B-2
<PAGE>
(i)     dividing the total number of shares of Company Common Stock outstanding
        immediately prior to the stock dividend, subdivision or combination, by
        an amount equal to the total number of shares of Company Common Stock
        outstanding immediately after such stock dividend, subdivision or
        combination; and

(ii)    multiplying the result of clause (i) above by the actual Conversion
        Price in effect immediately prior to such stock dividend, subdivision or
        combination.

and the total of shares of Company Common Stock thereafter issuable and
deliverable on conversion of the this Note shall be the number of shares
obtained by applying the Conversion Price as so adjusted. 

        (B)   In case of any capital reorganization or any
reclassification of the shares of Company Common Stock (other than as a result
of a stock dividend, subdivision or combination, as aforesaid), or in case of
any consolidation with or merger of Company into or with another corporation,
or the sale, lease or other disposition of the properties of Company as an
entirety or substantially as an entirety, then as a part of such
reorganization, reclassification, consolidation, merger, sale, lease or other
disposition, as the case may be, lawful provision shall be made so that the
holder of this Note shall have the right thereafter to receive upon conversion
thereof the kind and amount of shares of stock or other securities or property
which such holder would have been entitled to receive if, immediately prior to
such reorganization, reclassification, consolidation, merger, sale, lease or
other disposition, such holder had held the number of shares of Company Common
Stock which were then issuable upon the conversion of this Note.  In any such
case, appropriate adjustment shall be made in the application of the
provisions set forth herein with respect to the rights and interests
thereafter of the holders of record of this Note, to the end that the
provisions set forth herein (including provisions with respect to adjustments
of the Conversion Price) shall thereafter be applicable, as nearly as
reasonably may be, in relation to any shares of stock or other property
thereafter deliverable upon the conversion of this Note.

        (C)   Whenever the Conversion Price is adjusted, as herein pro-
vided, the Company shall forthwith transmit to the registered holder of this
Note a statement signed by the Secretary or the Treasurer of Company, stating
the adjusted Conversion Price determined as herein provided.  Such statement
shall specify in detail the facts requiring such adjustment.  

  4.3.  RIGHTS OF CONVERSION.

        (a)    At any time up through the second business day prior to a
date fixed for redemption of this Note, whether at its Maturity Date or by
optional redemption in accordance with Section 3 above (unless Company shall
default in payment due upon the redemption thereof), at the election of the
holder of this Note and subject to the terms and conditions set forth herein,
any and all of the principal and accrued and unpaid interest of this Note may
be converted into fully paid and nonassessable shares of Company Common Stock
at the Conversion Price then in effect (after taking into account any
adjustment thereof as hereinabove set forth).

        (b)   The value of this Note, for the purpose of determining the
number of shares of Company Common Stock to be issued in accordance with any
such conversion, shall be deemed to be principal amount tendered for
conversion and any accrued and unpaid interest thereon to the date this Note
is so tendered to Company for conversion hereunder; provided, however, that
the Company at its option may elect to pay such accrued and unpaid interest in
cash to the holder of this Note within two (2) business days after this Note
is tendered for conversion in lieu of converting such interest obligation into
shares of Company Common Stock.



                                    B-3

of this Note shall execute and deliver to the Company at its principal office
in the State of Pennsylvania a duly executed notice of the holder's election
to convert all or any portion of this Note into Company Common Stock.  Such
notice shall specify the principal amount of this Note to be so converted and

for shares of Company Common Stock issuable on such conversion shall be
issued.

Stock shall be issued upon any such conversion of this Note, and in lieu

covenants and agrees to reserve unissued, out of the authorized but unissued
shares of Company Common Stock, that number of shares sufficient to provide
for conversion of all the principal of this Note then outstanding for Company
Common Stock as provided for herein.

Note, by his or her acceptance hereof, represents and warrants that this Note
has been acquired by said holder for its own account for investment, and

        not vacated or stayed within 30 days from the date of entry thereof (A)
        appointing a trustee or receiver of the Company or of any substantial

  its debts generally as they become due.

  6.1.  RIGHT OF ACCELERATION.  All of the unpaid principal and interest

Section 7.1 shall have become effective, to the knowledge of the Company any
event occurs as a result of which a prospectus included therein relating to

misleading, the Company will promptly notify the holder or holders of record
of this Note and/or shares of Common Stock covered by such prospectus thereof

        (c)   The Company agrees to furnish to the holders of the Notes
  and of the shares of Common Stock acquired upon the conversion thereof,
  a prospectus containing certified financial statements and other
  information meeting the requirements of the Securities Act and the rules
  and regulations thereunder and relating to shares of Common Stock
  issuable upon conversion of the Notes.  The furnishing of such prospec-
  tus shall be at the expense of the Company.

        (d)   The Company will use its best efforts to qualify the shares
  of Common Stock covered by any registration statement or post-effective
  amendment for public offering or sale on the effectiveness thereof in
  the State of New York and such other jurisdictions, if any, as the
  Company shall determine. The filing fees and reasonable fees and
  expenses of counsel in connection with such qualification in the State

                                    B-2
<PAGE>
(i)     dividing the total number of shares of Company Common Stock outstanding
        immediately prior to the stock dividend, subdivision or combination, by
        an amount equal to the total number of shares of Company Common Stock
        outstanding immediately after such stock dividend, subdivision or
        combination; and

(ii)    multiplying the result of clause (i) above by the actual Conversion
        Price in effect immediately prior to such stock dividend, subdivision or
        combination.

and the total of shares of Company Common Stock thereafter issuable and
deliverable on conversion of the this Note shall be the number of shares
obtained by applying the Conversion Price as so adjusted. 

        (B)   In case of any capital reorganization or any
reclassification of the shares of Company Common Stock (other than as a result
of a stock dividend, subdivision or combination, as aforesaid), or in case of
any consolidation with or merger of Company into or with another corporation,
or the sale, lease or other disposition of the properties of Company as an
entirety or substantially as an entirety, then as a part of such
reorganization, reclassification, consolidation, merger, sale, lease or other
disposition, as the case may be, lawful provision shall be made so that the
holder of this Note shall have the right thereafter to receive upon conversion
thereof the kind and amount of shares of stock or other securities or property
which such holder would have been entitled to receive if, immediately prior to
such reorganization, reclassification, consolidation, merger, sale, lease or
other disposition, such holder had held the number of shares of Company Common
Stock which were then issuable upon the conversion of this Note.  In any such
case, appropriate adjustment shall be made in the application of the
provisions set forth herein with respect to the rights and interests
thereafter of the holders of record of this Note, to the end that the
provisions set forth herein (including provisions with respect to adjustments
of the Conversion Price) shall thereafter be applicable, as nearly as
reasonably may be, in relation to any shares of stock or other property
thereafter deliverable upon the conversion of this Note.

        (C)   Whenever the Conversion Price is adjusted, as herein pro-
vided, the Company shall forthwith transmit to the registered holder of this
Note a statement signed by the Secretary or the Treasurer of Company, stating
the adjusted Conversion Price determined as herein provided.  Such statement
shall specify in detail the facts requiring such adjustment.  

  4.3.  RIGHTS OF CONVERSION.

        (a)    At any time up through the second business day prior to a

holder of this Note and subject to the terms and conditions set forth herein,
any and all of the principal and accrued and unpaid interest of this Note may
be converted into fully paid and nonassessable shares of Company Common Stock

adjustment thereof as hereinabove set forth).

        (b)   The value of this Note, for the purpose of determining the
number of shares of Company Common Stock to be issued in accordance with any
such conversion, shall be deemed to be principal amount tendered for
conversion and any accrued and unpaid interest thereon to the date this Note
is so tendered to Company for conversion hereunder; provided, however, that
the Company at its option may elect to pay such accrued and unpaid interest in
cash to the holder of this Note within two (2) business days after this Note

Section 7.1 shall have become effective, to the knowledge of the Company any
event occurs as a result of which a prospectus included therein relating to

material fact, or would not state a material fact necessary to make the
statements therein, in the light of the circumstances then existing, not
misleading, the Company will promptly notify the holder or holders of record
of this Note and/or shares of Common Stock covered by such prospectus thereof

post-effective amendment pursuant to this Section 7:

  Federal commission and will make available to its security holders, as
  soon as practicable, an earnings statement (which need not be audited)

<PAGE>
  covering a period of at least 12 months, but not more than 18 months,
  beginning with the first month after the effective date of the
  registration statement or post-effective amendment, as the case may be,

  the Securities Act.

        (b)   Each holder of the shares of Common Stock covered by such
  registration statement or post-effective amendment of a registration
  statement, as the case may be, will furnish in writing to the Company
  such information regarding such holder and its proposed plan of
  distribution of such shares as the Company shall reasonably request.
  
        (c)   The Company agrees to furnish to the holders of the Notes
  and of the shares of Common Stock acquired upon the conversion thereof,
  a prospectus containing certified financial statements and other
  information meeting the requirements of the Securities Act and the rules
  and regulations thereunder and relating to shares of Common Stock
  issuable upon conversion of the Notes.  The furnishing of such prospec-
  tus shall be at the expense of the Company.

        (d)   The Company will use its best efforts to qualify the shares
  of Common Stock covered by any registration statement or post-effective
  amendment for public offering or sale on the effectiveness thereof in
  the State of New York and such other jurisdictions, if any, as the
  Company shall determine. The filing fees and reasonable fees and
  expenses of counsel in connection with such qualification in the State
  of New York shall be at the expense of the Company.

and to induce the Beneficiaries to invest in Vista Notes issued by Vista-

<PAGE>

5.      w.net will receive 300,000 warrants to acquire WSM Consultants, Ltd.
        shares exercisable at .25 on July 2, 1998 or any date whether pre or
        post 7/2/98 if a merger has been consummated under the provisions of
        items 7 or 8 below then exerciseable simultaneously with the merger.  

  After July 2 and assuming no merger exercisable at 50 cents a share. The
  exercise period at 50 cents will extend through 6/30/2000.

  The 300,000 warrants will have an antidilution clause which will protect
  w.net against dilution for the period, i.e., number of warrants and
  exercise price will be adjusted by dividing $75,000 by the lowest price
  that shares are sold for, or issued for in lieu of services or options
  granted or warrants issued and with the quotient increasing the number
  of warrants issued to w.net. The exercise price will then be adjusted to
  that price, if lower.

6.      w.net will own and maintain all equipment which it acquires and places
        on the premises of WSM operations and will have the right to remove the
        same at their discretion.

        (exclusive of any personal or related party liabilities due to current
        WSM principals) for 25% of the w.net equity if w.net and/or ACE has
        caused at least $750,000 of new funding including the amounts funded in
        item 3 to be infused into WSM and/or w.net on a combined basis. If the
        option of w.net as outlined in 2(iii) above is exercised, the provisions
        of item 7 will be extended through 6/30/1998.

8.      Conversely, WSM will have the non-cancellable right until January 31,
        1998 to trade all of its net assets and operations (exclusive of any
        personal liabilities due to current WSM principals) which right will not
        be contingent upon performance criteria. The right of WSM will be
        extended through 7/31/98 if w.net exercises its option as outlined in
        2(iii).

9.      Warren Schmidt and Pat Rooney will take no salary for either WSM or
        w.net except out of profits of these operations or after full funding
        and/or merger as herein described.

10.     WSM and w.net will perform all intercompany work for each other using
        existing personnel at no additional cost. W.net will fund on a current
        basis the additional personnel necessary to create new business acquired
        by w.net and pay WSM 20% over that cost. The definition of cost will be
        negotiated on a project by project basis. The intent of the parties is
        for cost to represent actual out of pocket expenses.

11.     Upon the merger of WSM and w.net, w.net will give to WSM an option to
        acquire 300,000 shares of the newly merged company for $75,000. The
        option will have an exercise period through 6/30/2000.

12.     WSM has agreed that it would issue an option to T. Tobias for 101,600
        shares of its common stock exercisable $101.60 through 6/30/2000.

  W.net has agreed that it will issue an option to T. Tobias for 80,000
  shares of its common stock exercisable at 25 cents per share through
  6/30/2000.

  Both options set will be issued or granted only if a merger of WSM and
  w.net is consummated.

13.     The transaction herein contemplated will cause the following
        capitalizations to result for WSM and w.net.

        200,000 shares of Common Stock, par value $0.005 per share

                        ~~~~~~~~~~~~~~~~~~~~~~~~~~~

THE SECURITIES OFFERED BY THIS AGREEMENT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE "ACT").  ACCORDINGLY, NO RESALE OR OTHER TRANSFER
OF SUCH SECURITIES OR ANY INTEREST THEREIN MAY BE MADE EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT UNLESS THE ISSUER HAS RECEIVED
AN OPINION OF COUNSEL SATISFACTORY TO IT THAT SUCH TRANSFER DOES NOT REQUIRE
REGISTRATION UNDER THE ACT.

All references to Common Stock of Vista Technologies Inc. in this Agreement
are after giving effect to a one (1) for five (5) reverse stock split effected
with respect to its authorized and outstanding common stock pursuant to a
Certificate of Amendment recorded with the Secretary of State of Nevada on

                        ~~~~~~~~~~~~~~~~~~~~~~~~~~~

Vista Technologies Inc.
126 E. 56th Street, 3rd Floor
New York, NY  10022


  1.    SUBSCRIPTION TO SHARES. PHARMA PATCH PLC, a public limited company
organized under the laws of the Republic of Ireland with its principal offices
at Pharma Patch PLC, 15-16 FitzWilliam Place, Dublin 2, Ireland (herein called
"Pharma Patch") hereby subscribes for the purchase of 200,000 shares of the
Common Stock, par value $0.005 per share, in Vista Technologies Inc., a Nevada
corporation ("VISTA"), for the account of the Foreign Investor at a purchase
price of Five Hundred Thousand Dollars ($500,000.00) United States funds,
payable in cash on March 1, 1996.

  2.    REPRESENTATIONS AND WARRANTIES OF PHARMA PATCH.   In connection
with this Agreement and the transactions contemplated herein, Pharma Patch
represents and warrants to VISTA as follows:

  2.1.  Pharma Patch is duly organized and validly existing as a public
limited company under the laws of the Republic of Ireland.  Pharma Patch
acknowledges that its chief executive officer is a director of VISTA and that
Pharma Patch is familiar with the business, financial condition and plan of
operations of VISTA.

<PAGE>
  2.2.  Pharma Patch acknowledges that the VISTA Common Stock purchased
hereunder has not been registered under the U.S. Securities Act of 1933, as
amended ("Securities Act") or qualified under applicable state securities laws
and that the transferability thereof is restricted by the registration
provisions of the Securities Act as well as such state laws.  Based upon the
representations and agreements being made by Pharma Patch herein, the VISTA
Common Stock is being sold pursuant to an exemption from such registration
provided by Section 4(2) of the Securities Act for transactions not involving
a public offering.  Pharma Patch understands that the certificates
representing the VISTA Common Stock will bear a legend indicating that
transfer of these securities is restricted by reason of the fact that they
have not been so registered.

        Pharma Patch represents that it is acquiring the Common Stock for
its own account, for investment purposes only, and not with a view to resale
or other distribution thereof, nor with the intention of selling, transferring
or otherwise disposing of all or any part of such securities based upon any
particular event or circumstance except upon full compliance with all
applicable provisions of the Securities Act.  Pharma Patch further understands
and agrees that the VISTA Common Stock may be sold only if subsequently
registered under the Securities Act and qualified under any applicable state
securities laws or, in the opinion of counsel satisfactory to VISTA, an
exemption from such registration and qualification is available, and that any
routine sales of securities made in reliance upon Rule 144 promulgated by the
Commission can be made only in the amounts set forth in and pursuant to the
other terms and conditions, including applicable holding periods, of that
Rule.

  2.3.  Pharma Patch has sufficient knowledge and experience of financial
and business matters so that it is able to evaluate the relative merits and
risks of purchasing the VISTA Common Stock.  Pharma Patch is aware that an
investment in the VISTA Common Stock is a speculative investment, is not
liquid, and involves a high degree of risk of loss.  Pharma Patch acknowledges
that VISTA has made available to Pharma Patch, prior to this subscription, the
opportunity to ask questions of, and receive written answers from, authorized
representatives and executive officers of VISTA concerning the operations and
financial condition of VISTA and its consolidated subsidiaries, and any other
relevant matters, and to obtain any additional written information, to the
extent that VISTA possesses such information or can acquire it without
unreasonable effort or expense, necessary to verify the accuracy of the
information provided by VISTA to Pharma Patch.

  2.4.  This Agreement has been duly authorized, executed and delivered by
Pharma Patch and is a valid and binding agreement enforceable in accordance
with its terms, subject only to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general application to or
affecting creditors' rights generally and to general principles of equity. 
Pharma Patch has full power and authority necessary to enter into this
Agreement and to perform its obligations hereunder.

  2.5.  The execution and delivery of this Agreement, and the consummation
of the transactions contemplated herein, do not and will not conflict with or
result in a breach by Pharma Patch of any of the terms or provisions of, or
constitute a default under, its charter documents, its memorandum or articles
of association or incorporation, its by-laws, any action of its directors or
shareholders, or any indenture, mortgage, deed of trust or other agreement or
instrument to which Pharma Patch is a party or by which it or any of its
properties or assets are bound, or any existing applicable law, rule or
regulation or any applicable decree, judgment or order of any court,
regulatory body, administrative agency or other governmental body having
jurisdiction over Pharma Patch.

periods ended June 30, 1995 and September 30, 1995.

  3.3.  VISTA has made available to Pharma Patch copies of audited
consolidated financial statements of VISTA and its consolidated subsidiaries

consolidated subsidiaries; (c) fair presentations of the financial condition
and results of operations of VISTA and its consolidated subsidiaries as of the

consistent basis throughout the periods indicated.  Since September 30, 1995,
there has not been (a) any material adverse change in the financial condition,
assets, liabilities, personnel or business of VISTA and its consolidated
subsidiaries from that reflected in the Vista Financial Statements as of
September 30, 1995; (b) any damage, destruction or loss, whether or not
covered by insurance, materially adversely affecting VISTA or its consolidated
subsidiaries; (c) any event or condition or series of events or conditions
which could, individually or in the aggregate, reasonably be expected to have
a material adverse effect on VISTA or its consolidated subsidiaries; or (d)
any development which could or will have a material adverse effect on VISTA or
its consolidated subsidiaries or their business operations.  Pharma Patch
acknowledges that VISTA has terminated and rescinded all executory obligations
under its prior agreements with Medical Development Resources, Inc. ("MDRI")
and certain of its stockholders, has written down to zero VISTA's prior
investments in MDRI and its subsidiaries KMI I, Inc. and Micra Instruments
Limited, and that MDRI and its subsidiaries are not included as consolidated
subsidiaries of VISTA for purposes of the foregoing representations relating
to the Vista Financial Statements as of September 30, 1995.

  3.3.   The VISTA Common Stock to be sold to Pharma Patch hereunder, when
issued and delivered upon receipt of the purchase price, will be duly and
validly authorized and issued, fully paid and nonassessable securities of
VISTA and will not subject the holders thereof to personal liability by reason
of being such holders.

  3.4.   This Agreement has been duly authorized, executed and delivered
by VISTA and is a valid and binding agreement enforceable in accordance with
its terms, subject only to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general application to or
affecting creditors' rights generally and to general principles of equity. 
VISTA has full power and authority necessary to enter into this Agreement and
to perform its obligations hereunder.

consummation of the transactions contemplated herein, do not and will not
conflict with or result in a breach by VISTA of any of the terms or provisions
of, or constitute a default under, its articles of incorporation, its by-laws,
any action of its directors or stockholders, or any indenture, mortgage, deed
of trust or other agreement or instrument to which it is a party or by which
it or any of its properties or assets are bound, or any existing applicable
law, rule or regulation or any applicable decree, judgment or order of any
court, regulatory body, administrative agency or other governmental body
having jurisdiction over the undersigned or any of its properties or assets.

  3.6.  REGISTRATION RIGHTS.    In the event the Common Stock sold to
Pharma Patch hereunder has not been registered by VISTA under the Securities
Act prior to September 30, 1996 by a registration statement then effective
under the Securities Act, at any time after September 30, 1996, Pharma Patch
may make a written request for the registration of such Common Stock under the
Securities Act (a "Demand Registration").  Notwithstanding the foregoing
provisions of this Section 3.6:

(a)     VISTA shall have no obligation to register Common Stock for the account
        of Pharma Patch at any time during a period of twelve (12) months
        following any notice in which  Pharma Patch was offered the opportunity
        of participating in a registration statement which has become effective
        under the Securities Act.

(b)     After March 31, 1997, VISTA at its discretion shall have no obligation
        during any fiscal year of VISTA thereafter to register Common Stock for
        the account of Pharma Patch unless the demand for registration is
        received by VISTA within a period of four (4) months following the
        beginning of such VISTA fiscal year on April 1.

(c)     VISTA shall have no obligation to register Common Stock for the account

        Act.

(d)     VISTA shall have no obligation to register Common Stock for the account
        of  Pharma Patch which may then be sold by  Pharma Patch in accordance
        with the provisions of Rule 144 promulgated under the Securities Act.

        3.6.1.      Upon receipt of any such demand, VISTA will use its
best efforts to effect such Demand Registration and will maintain the
prospectus included in any registration statement which may be so filed
current for a period of at least nine (9) months subsequent to the effective
date of such registration statement.

be sold and shall also specify the intended method of disposition thereof and
any other information within the unique knowledge and control of Pharma Patch
necessary for VISTA to comply with applicable registration requirements of the
Securities Act.

2.      SIX-MONTH OPTION TO PHARMA PATCH and EQUITABLE ADJUSTMENT PROVISION

the transactions provided by this Agreement, VISTA hereby grants PHARMA PATCH
an option to purchase up to an additional 250,000 shares of VISTA common stock
at an option exercise price of $2.50 per share (the "$2.50 Option").  The
$2.50 Option may be exercised by PHARMA at any time, or from time to time, at
any time during the six month period ending September 30, 1996 for any portion
of all of the VISTA shares covered thereby by providing written notice of
PHARMA PATCH's election to exercise accompanied by payment in cash to VISTA of
the applicable option exercise price.   Within five business days thereafter,
VISTA shall issue and deliver to PHARMA PATCH certificates evidencing the
shares of VISTA common stock purchased pursuant to such option exercise.

  2.2.  EQUITABLE ADJUSTMENT FOR CHANGES IN CAPITALIZATION.   If there

1-for-5 reverse stock split as to VISTA common stock approved by its
stockholders in 1995), or any extraordinary or stock dividend hereafter paid
on or with respect to the common stock of VISTA or TCPI prior to the date that
such shares are delivered to the parties to this Agreement, appropriate and
equitable adjustments shall be made hereunder with respect to the number of
shares of VISTA common stock or TCPI common stock delivered under Section 1
and Section 2 of this Agreement such that the aggregate relative rights and
obligations of the parties hereto shall not be adversely affected by any such
action.

3.      U.S. SECURITIES LAWS.

   All of the parties hereto acknowledge that the common stock of VISTA
and the common stock of TCPI are traded in the United States securities
markets.  Neither the Vista SHARES, the Vista WARRANTS, the Pharma Patch NOTE
nor the TCPI SHARES to be exchanged hereunder have been registered under the
U.S. Securities Act of 1933, as amended (the "Securities Act") or qualified
under the Trust Indenture Act of 1939, as amended (the "Indenture Act").  Each
party acknowledges that the exchange of securities hereunder is among
sophisticated investors who are acquiring such securities for their own
account for investment, and not with a view to the resale or other
distribution thereof, in connection with a private placement offer, sale and
exchange relating to such securities.  Each party acknowledges it is familiar
with and understands the terms of applicable securities laws of the United
States, and has had the opportunity to consult with its legal counsel
concerning such laws.  Accordingly, each party acknowledges that the
subsequent transfer of all securities covered by this Agreement within the
United States markets or otherwise within the jurisdiction of the United
States is restricted by the Securities Act and/or the Indenture Act as well as
state laws within the United States.


                                     3

4.      VISTA ACKNOWLEDGEMENT OF CONTRACTUAL "LOCK-UP" PROVISIONS AS TO THE TCPI
        SHARES

  4.1.  VISTA acknowledges that the TCPI SHARES to be transferred to VISTA
under the provisions of Section 1.5 of this Agreement are subject to certain
contractual restrictions on transfer under agreements to which PHARMA PATCH is
a party arising as a result of PHARMA PATCH's acquisition of TCPI common stock
and amendments thereto concerning a proposed underwriting of a portion of such
shares, copies of which have been delivered to VISTA  (collectively, the
"Lock-Up Agreements").  VISTA covenants and agrees that it will observe all of
such contractual restrictions applicable to the TCPI SHARES as if VISTA had
been a party to such "Lock-Up Agreements" in the name, place and stead of
PHARMA PATCH.

5.      VISTA TAG-ALONG RIGHTS AS TO PHARMA PATCH SALE OF TCPI COMMON STOCK.

  5.1.  The parties acknowledge that PHARMA PATCH proposes to sell a
portion of the TCPI shares of common stock currently owned by PHARMA PATCH,
exclusive of the TCPI SHARES to be transferred to VISTA under Section 1.5 of
this Agreement, in a pending proposed underwritten public offering of TCPI
securities.  The parties acknowledge and agree that the provisions of Section
5.2 of this Agreement shall not apply to any shares of TCPI common stock sold
for the account of PHARMA PATCH upon the closing of the aforesaid proposed
underwritten public offering of TCPI securities or upon the closing of any
over-allotment option relating thereto.   However, PHARMA PATCH covenants and
agrees it will reserve from a portion of such proceeds an amount necessary to
discharge in full the unpaid obligations of PHARMA PATCH under the Pharma
Patch NOTE and shall promptly pay the same to VISTA whether at, before, or
after the original maturity date thereof.

  5.2.  Subject to Section 5.1 above, in the event PHARMA PATCH hereafter
proposes to sell for its own account shares of TCPI common stock owned by
PHARMA PATCH, whether in a private transaction or pursuant to a subsequent
underwritten or secondary public offering of TCPI common stock for the account
of PHARMA PATCH, then VISTA shall have the right to participate (the
"Tag-Along Right") in such sale or sales with respect to any of the TCPI
SHARES then held by VISTA on a pari passu basis (i.e., for up to 50% of the
total shares of TCPI common stock sold for the combined accounts of PHARMA
PATCH and VISTA) for the same consideration per share and otherwise on the
same terms and conditions as PHARMA PATCH agrees to sell its TCPI common
shares.  A distribution of TCPI common stock to the shareholders of PHARMA
PATCH in a transaction of the type contemplated by Section 9.6 of this
Agreement shall not be deemed a sale of TCPI common stock for the purposes of
this Section 5.2.  In the event rights of sale for which a Tag-Along Right may
exist are not assignable by PHARMA PATCH to VISTA, then PHARMA PATCH agrees to
sell for its own account a sufficient number of TCPI common shares to account
for the Tag-Along Right and VISTA shall transfer an equal number of TCPI
common shares to PHARMA PATCH against payment to VISTA of its share from net
proceeds from such sale.  If circumstances occur which give rise to a
Tag-Along Right, then PHARMA PATCH shall give written notice thereof to VISTA
providing all particulars of the proposed sale of TCPI common stock and
advising VISTA of its Tag-Along Right.  VISTA may elect to exercise its Tag-
Along Right by written notice to PHARMA PATCH within ten (10) business days
thereafter and shall state the number of TCPI SHARES that VISTA wishes to
sell, up to the maximum


                                     4
<PAGE>
number permitted (being its pari passu amount referred to above and as
disclosed in the notice to given to VISTA by PHARMA PATCH).   If VISTA gives
written notice indicating that it wishes to participate in the proposed sale,
VISTA shall be obligated to sell that number of TCPI SHARES specified in its
written acceptance notice upon the same terms and conditions as PHARMA PATCH
is selling shares of TCPI common stock for its own account conditional upon,
and contemporaneous with, completion of the transaction of purchase and sale.

6.      ADDITIONAL REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF VISTA.

   VISTA hereby represents and warrants to PHARMA PATCH that:

  6.1.  ORGANIZATION AND AUTHORITY.   VISTA is a corporation duly organ-

insolvency, moratorium and other laws affecting creditors' rights generally
and by general equitable principles.  The execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby will
not result in the creation of any lien, charge or encumbrance of any kind or
the acceleration of any indebtedness or other obligation of VISTA and are not
prohibited by, do not violate or conflict with any provision of, and do not
constitute a default under or a breach of (a) the charter or by-laws of VISTA,

the Securities and Exchange Commission complied with the Exchange Act in all
material respects.  None of the VISTA SEC Reports, as of their respective

not have the right to acquire any such interest, and does not control,

relationship with any such entity during the three years preceding this
Agreement.  Each subsidiary disclosed in the VISTA SEC Reports is a
corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation and has full power and authority
and all requisite rights, licenses, permits and franchises to own, lease and
operate its assets and to carry out the business in which it is engaged
(except that VISTA makes no representations or warranties as to Medical
Development Resources, Inc. and its subsidiaries).  The percentage ownership
held by VISTA in each such subsidiary is accurately stated in the VISTA SEC

Medical Development Resources, Inc. and its subsidiaries).  The parties
understand and agree that references hereinafter to VISTA's "consolidated
operating subsidiaries" do not include Medical Development Resources, Inc. and
its subsidiaries.

registered under the Securities Act of 1933 and may be reoffered and sold only
if registered or if an exemption from such registration is available in the
opinion of counsel satisfactory to the issuer."

  WHEREAS, TPR, SRL and WPI each own of record and beneficially 300,000

"Closing Date") and shall take place at the offices of Multibreen, B.V., at
Statenhof Building, Reaal 5-V, 2350 AA Leiderdorp, The Netherlands, unless
another time and place is mutually agreed to by the parties.  Upon the

"Securities Act").  Each party acknowledges that the exchange of securities
hereunder is among investors who are not U.S. persons as defined in Rule

familiar with and understands the terms of Regulation S, and has had the
opportunity to consult with its legal counsel concerning this Agreement and
Regulation S.  Accordingly, each party acknowledges that the subsequent
transfer of all securities covered by this Agreement within the United States
markets or otherwise within the jurisdiction of the United States is
restricted by the Securities Act as well as state laws within the United
States.

3.      REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF TPR, SRL AND WPI.  Each of
TPR, SRL and WPI represents and warrants to PHARMA PATCH that:

  3.1.  such party is a body corporate duly organized, validly existing

indicated in the preamble to this Agreement, with all requisite power and
authority to own its property and assets, to carry on its business as it is
now being conducted and to enter into and execute this Agreement and perform
its obligations hereunder. 

  3.2.  at the Closing Date, all of the Vista SHARES to be transferred,
assigned and delivered by such party to PHARMA PATCH hereunder will be owned
beneficially and of record by such party, shall be validly issued, fully paid
and nonassessable securities of VISTA, and such party owns, possesses and has
good and marketable title to transfer such Vista SHARES to PHARMA PATCH at

interests or other adverse claims whatsoever or howsoever arising.

  3.3.  such party is not a "U.S. Person" as that term is defined in Rule
902(o) of Regulation S; such party was not formed specifically for the purpose
of investing in Regulation S securities or formed specifically for the purpose
of investing in this Agreement or the securities of PHARMA PATCH; such party
is not registered as an issuer under the Securities Act and is not required to
be registered with the U.S. Securities and Exchange Commission under the
Investment Company Act of 1940; such party has no reason to believe that any
offer to enter into this Agreement has been made by PHARMA PATCH to such party
in the United States; at the times of the original offer relating to, and
execution of, this Agreement, such party was located and resident outside the
United States; and such party is entering into this Agreement and acquiring
Pharma Patch ADRs hereunder for its own account for investment, and not on
behalf of any U.S. Person as defined in Rule 902(o) of Regulation S or with a
view to the distribution of such securities.

  3.4.  neither such party, nor any of its affiliates nor any person
acting on its behalf or any behalf of any such affiliate, has engaged, or will
engage, in any activity undertaken for the purpose of, or that could
reasonable be expected to have the effect of, conditioning the markets in the
United States for any of the securities of PHARMA PATCH or VISTA, including
but not limited to effecting any sale or short sale or the acquisition of any
put option relating to the securities of PHARMA PATCH for the account of such
party or any of its affiliates prior to the expiration of any restricted
period contained in Regulation S or engaging in any course of conduct that
would have the effect of influencing the public market price of such
securities (any such activity, or any other course of conduct defined as a
Directed Selling Effort in Rule 902 of Regulation S, being herein called a
"Directed Selling Effort");  such party and its representatives have not
conducted any Directed Selling Effort and will not engage in any such Directed
Selling Effort within the United States through the expiration of any
restricted period set forth in Rule 903 of Regulation S.

  3.5.  such party agrees that all offers and sales of any securities of
PHARMA PATCH or VISTA for the account of such party or for the account of any
of its affiliates as of the date hereof and through the expiration of the any
restricted period set forth in Rule 903 of Regulation S shall not be made to
U.S. Persons or for the account or benefit of U.S. Persons and shall otherwise
be made in compliance with the provisions of Regulation S and any other
applicable provisions of the United States securities laws.

  3.6.  such party acknowledges and agrees that following the expiration
of any restricted period provided by Rule 903 of Regulation S, any interest in
this Agreement or in the Pharma Patch ADRs may be resold within the
jurisdiction of the United States or to U.S. Persons [as defined in Rule
902(o) of Regulation S] by or for the account of the parties hereto only  (i)
pursuant to a registration statement under the Securities Act, or  (ii)
pursuant to an exemption from such registration and only following the
expiration of any restricted period required by Regulation S.

  3.7.  such party acknowledges that if any subsequent transfer of the
Pharma Patch ADRs is to be made in reliance upon an exemption under the
Securities Act, the issuer of the securities being so transferred may require
an opinion of counsel satisfactory to the issuer that such transfer may be
made pursuant to an applicable exemption under the Securities Act;  such party
further acknowledges that, so long as appropriate, a legend similar to the
following may appear on the certificates representing the Pharma Patch ADRs: 
"These securities have not been registered under the Securities Act of 1933
and may be reoffered and sold only if registered or if an exemption from such
registration is available in the opinion of counsel satisfactory to the
issuer."

  3.8.  such party has sufficient knowledge and experience in financial
and business matters so that it is able to evaluate the merits and risks of
this Agreement and an investment in restricted securities


Exchange Agreement                                                   -3-
<PAGE>

of PHARMA PATCH;  such party has had substantial experience in previous
private and public purchases of speculative and restricted securities,
understands that an investment in PHARMA PATCH securities is speculative, and

other holder of this Bridge Note, by acceptance hereof, represents and
warrants that this Bridge Note has been acquired by said holder for its own
account for investment, and acknowledges that any proposed sale, assignment or
transfer of this Bridge Note is prohibited unless such sale, assignment or
transfer in the opinion of counsel for the Company will not require the prior

1939, as amended.

  5.    DEFAULT AND ACCELERATION.   If one or more of the following events

        seeking any such judicial order or shall make an assignment for the
        benefit of its creditors or shall admit in writing its inability to pay
        its debts generally as they become due.

then all of the unpaid principal and interest of this Bridge Note shall become
immediately due and payable upon demand made by the holder of this Bridge Note
if any one or more Events of Default shall occur and be continuing at the time

<PAGE>
business so long as such duties are reasonably related to the Employee's

  this Agreement shall terminate


- -----------------------------------------------------------------
Thomas A. Schultz Employment Agreement                          4
<PAGE>
  immediately and, except as expressly set forth in this paragraph, the
  Company shall have no further liability hereunder to Employee. The
  Company shall continue to pay to Employee his salary and continue stock

  injury, illness or physical or mental disability, he is prevented from

  of total disability shall be made by the Board of Directors of the
  Company, but said decision shall not be unreasonable or arbitrary and
  shall be supported by the opinion (at the Company's expense) of at least
  one licensed physician unless Employee shall without justification fail
  to submit to the necessary physical or mental examinations. It is
  understood that Employee's occasional sickness of short duration shall
  not result in Employee being considered totally disabled, and Employee
  shall continue to be compensated hereunder during such periods of
  occasional sickness so long as they shall not exceed twelve (12) days In

  Agreement for cause. For the purposes of this Agreement, a termination
  for "cause" shall mean a termination resulting from a determination by
  the Company's Board of Directors that Employee (i) has committed a
  felony or act of moral turpitude which would materially injure the
  Company or its reputation or, (ii) has intentionally or willfully and
  repeatedly breached his duties hereunder in a material respect and, if
  curable, has failed to cure the same within thirty (30) days after

  whether or not curable.  In the event of termination for cause, the
  Company shall have no further liability hereunder to Employee from and
  after the date of such termination.

  (d) TERMINATION WITHOUT CAUSE. Termination of Employee for any reason
  other than in paragraphs 6(a), 6(b), and 6(c) hereof shall be considered
  Termination Without Cause.  In addition, Employee's resignation from the
  employ of the


- -----------------------------------------------------------------
Thomas A. Schultz Employment Agreement                          5
<PAGE>
  Company shall be deemed Termination Without Cause ("Constructive
  Discharge") if resulting from:  1) a material reduction in cash
  compensation (excluding performance bonuses) or other benefits other
  than as a result of a decrease in compensation payable to Employee and
  to all other executive officers of Company on the basis of Company's
  financial performance; 2) a change in reporting relationships or a
  significant change in the nature or scope of Employee's
  responsibilities, authorities, powers,  functions or duties  as
  President and Chief Executive; 3) a requirement imposed by Company that
  Employee relocate to an office that is more than 25 miles from his
  current residence; 4) failure of Company materially to perform its
  obligations pursuant to this Agreement. If Employee continues his
  employment with the Company after a Constructive Discharge event occurs,
  that continuation shall not constitute a waiver of Employee's right to
  treat such event as an event of Termination Without Cause thereafter.

  (e) SALARY AND BENEFIT CONTINUATION UPON TERMINATION WITHOUT CAUSE. Upon
  the termination of Employee's employment with the Company for any reason
  whatsoever prior to the expiration of the original term or any annual
  renewal of the term of this Agreement, except for (i) termination upon
  death as set forth in paragraph 6(a) hereof; (ii) termination upon
  permanent disability as set forth in paragraph 6(b) hereof; (iii)
  termination for cause pursuant to paragraph 6(c) hereof; or (iv)

  hereof; then the Company within thirty (30) days after such termination,
  and in lieu of all other obligations of the Company hereunder, shall: 
  1) pay to Employee an lump-sum payment equal to his then base salary for
  a period equal to twelve (12) months;  2) continue vesting of
  outstanding Employee stock options for twelve (12) months from
  termination date (which provision shall be added to Employee's option(s)
  at the date(s) of grant from the beginning); 3) will provide Employee,
  at Company's cost, with employment benefits consisting of life, health,
  dental and long-term disability insurance for a period of 12 months

  Employee's cost.

                                    3

potentially be, in competition with the business activities of the Company

____________________________________________________________________________
                                                                               
                                    4
<PAGE>
  without justification fail to submit to the necessary physical or mental
  examinations.  It is understood that Employee's occasional sickness of
  short duration shall not result in Employee being considered totally
  disabled, and Employee shall continue to be compensated hereunder during
  such periods of occasional sickness so long as they shall not exceed

  intentionally or willfully and repeatedly breached his duties hereunder
  in a material respect and, if curable, has failed to cure the same
  within thirty (30) days after receiving written notice of such breach
  from the Board of the Company.  Such notice must be given to Employee
  following each claimed breach, whether or not curable.  In the event of
  termination for cause, the Company shall have no further liability
  hereunder to Employee from and after the date of such termination.

  (d) TERMINATION WITHOUT CAUSE.  Termination of Employee for any reason
  other than in paragraphs 6(a), 6(b), and 6(c) hereof shall be considered
  Termination Without Cause.  In addition, Employee's resignation from the
  employ of the Company shall be deemed Termination Without Cause 
  ("Constructive Discharge") if resulting from: 1) a reduction of more
  than 25% of monthly base salary in cash compensation (excluding
  performance bonuses) or other benefits other than as a result of a
  decrease in compensation payable to Employee and to all other executive
  officers of Company on the basis of Company's financial performance; 2)
  a change in reporting relationship to the Company President or a
  significant reduction in the nature or scope of Employee's
  responsibilities, authorities, powers, functions or duties as an
  Executive Vice President and Chief Operating Officer of the Company; 3)
  a requirement imposed by Company that Employee relocate to an office
  that is more than 25 miles from the Company's current headquarters;  4) 
  failure of Company materially to perform its obligations pursuant to
  this Agreement. If Employee continues his employment with the Company
  after a Constructive Discharge event occurs, that continuation 

____________________________________________________________________________
                                                                               
                                    5
<PAGE>
  shall not constitute a waiver of Employee's fight to treat such event as
  an event of Termination Without Cause unless (i) his employment under
  adjusted terms of employment after the Constructive Discharge Event
  shall continue for more than 12 months after such Constructive Discharge
  Event or (ii) his employment is subsequently terminated for cause under
  paragraph 6(c) above. Any waiver of a Constructive Discharge Event as a
  result of continued employment for more than 12 months thereafter shall
  not, however, be deemed a waiver as to any other Constructive Discharge
  Event which may subsequently occur.

  (e) SALARY AND BENEFIT CONTINUATION UPON TERMINATION WITHOUT CAUSE.

  reason whatsoever prior to the expiration of the original term or any
  annual renewal of the term of this Agreement, except for (i) termination
  upon death as set forth in paragraph 6(a) hereof; (ii) termination upon
  permanent disability as set forth in paragraph 6(b) hereof; (iii)
  termination for cause pursuant to paragraph 6(c) hereof; or (iv)
  Employee's voluntarily electing not to continue in the employment of the
  Company under conditions other than those set forth in paragraph 6(d)
  hereof; then the Company within thirty (30) days after such termination,
  and in lieu of all other obligations of the Company hereunder, shall: 1)
  pay to Employee an lump-sum payment equal to his then base salary for a
  period equal to twelve (12) months; 2) will provide Employee, at
  Company's cost, with employment benefits consisting of life, health,
  dental and long-term disability insurance for a period of 12 months
  after termination; and 3) enter into a Post-termination Consulting
  Agreement as defined below in paragraph 6(f) hereof.  Thereafter, any
  continuation of benefits under the Consolidated Omnibus Budget
  Reconciliation Act (COBRA) will be at Employee's cost.

  (f) POST-TERMINATION CONSULTING AGREEMENT.  Upon the Termination Without
  Cause, Employee will hold himself available to provide consulting
  services to the Company for a period terminating one year after the
  Termination Date (the "Consulting Period"). Employee will provide the
  consulting services only upon the request of the Company's Chief
  Executive Officer and for no more than ten hours per week (any period
  shorter than one week will include a proportionate number of hours) at
  such times and places as are mutually convenient to Employee and the
  Company. However, Employee will perform those services at times and
  places that do not reasonably conflict with his responsibilities to his 

____________________________________________________________________________

  contractor with the customary and usual independence associated
  therewith, and he will not be deemed an employee or agent of the Company
  or have the authority to bind, or to enter into any contract on behalf
  of, the Company, unless expressly authorized in writing to do so.  The
  Company will pay Employee a consulting fee of $150.00 per hour for each
  hour actually worked at the Company's request. The Company's Board of
  Directors has determined that Employee will be providing "substantial
  services" to the Company during the Consulting Period such that any
  option held by Employee on the Termination Date, if not fully vested at
  the time, will continue to vest during the Consulting Period according
  to its terms. Any option held by Employee at the Termination Date will
  remain exercisable for the current term of the option during the
  Consulting Period even though the employment of Employee will terminate
  on the Termination Date.

or after the term of his employment, disclose such secrets or processes to any
person, firm, corporation, association or other entity for any reason or
purpose whatsoever, nor shall the Employee make use of any such secrets or
processes for his own purposes or for the benefit of any person, firm,
corporation,  or other entity (except the Company) under any circumstances
during or after the term of his employment; provided that after the term of
his employment these restrictions shall not apply to such secrets and
processes which are then, or from tine to time thereafter, in the public
domain (provided that he was not responsible, directly or indirectly, for
permitting such secrets or processes to enter the public domain without the
Company's consent).


8.      COVENANT NOT TO COMPETE OR INTERFERE.  The Employee agrees that during
the term of this Agreement or for a period of one ( 1 ) year after the date of
Termination under this Agreement, whichever occurs first; (a) Employee shall
not intentionally interfere with, disrupt or attempt to disrupt the
relationship, contractual or otherwise between the

Company and any customer, supplier, lessor or employee of the Company or any
of its subsidiaries and (b) Employee shall not as a sole proprietor or
otherwise for his own account or as a partner, employee, officer, director,

provisions of this paragraph shall cover his activities in the whole of North
America, Europe and Asia (the "Territory"). The parties hereto agree that the
covenants contained in this paragraph (b) shall be construed as if the
covenants are divided into separate and distinct covenants in respect of each
of the products and services of the Business, each capacity in which the party
is prohibited from competing, and each part of the world in which such
competition is prohibited from taking place. The territorial restrictions
contained in this paragraph (b) are properly required for the adequate
protection of the Business and in the event any covenant or other provision
contained this paragraph (b) shall be deemed to be illegal, unenforceable, or
unreasonable by a court or other tribunal of competent jurisdiction. With
respect to any part of the Territory or otherwise, such covenant or provision
shall not be affected with respect to any other part of the Territory or
otherwise, and each of the parties hereto agrees and submits to the reduction
of said territorial restriction or other provisions to such an area or
otherwise, as said court shall deem reasonable. The parties further agree that
if any provision of this Agreement is found to be unenforceable, it shall not
affect the enforceability of the remaining provisions and the court shall
enforce all remaining provisions to the extent permitted by law

Company, or to any person or entity designated by the Company, at of the

and assignments and such other papers and documents as may be required of the
Employee to permit the Company or any person or entity designated by the
Company to file and prosecute the patent applications and, as to copyrightable
material, to obtain copyright thereof.

made during the term of Employee's employment if, during such period, the

irreparable harm and damages to the Company which cannot be adequately
compensated by a monetary award. Accordingly, in the event of breach or
threatened breach of such provisions by Employee, Employee expressly agrees
that the Company shall be entitled to the immediate remedy of a temporary
restraining order, preliminary injunction or such other form of injunctive or
equitable relief as may be used by any court of competent jurisdiction to
restrain or enjoin the Employee from breaching any such covenant or provision
or to specifically enforce the provisions hereof. Nothing herein shall be
construed as prohibiting the Company from pursuing any other remedies for such
breach or threatened breach.

and forgive any and all indebtedness;

        NOW THEREFORE IN CONSIDERATION OF the mutual covenants contained
herein, (the receipt and sufficiency whereof being hereby mutually
acknowledged by all parties hereto) the parties agree as follows:

1.            In consideration of Northeast releasing Vista of the operation
funding guarantee, Vista hereby transfers, conveys and assigns all right,
title and interest to its stock or ownership in Northeast.  Vista does hereby
forever releases and hold Vista harmless from any liability or claim of
ownership.  Northeast and the Northeast Parties similarly hereby jointly and
severally release and hold Vista and Vista's directors, officers, employees
and shareholders harmless from any liability or claim arising from Vista's

in Northeast in consideration of one dollar (the receipt and sufficiency of
which is hereby acknowledged).  Vista shall forthwith cause its nominees to
resign from the Board of Directors and as officers of Northeast.  Northeast
and its

                                                           Page 2

management shareholders shall provide these individuals with releases and
indemnities from personal liability in connection with such positions.
Northeast shall forthwith change its corporate name to delete "Vista" from its
corporate name.

2.            Vista hereby assigns to Cherry Development Corporation on behalf
of such nominee as it may designate all of its outstanding capital
contributions, advances and loans made by Vista to Northeast and/or its
subsidiary, in consideration of one dollar (the receipt and sufficiency of
which is hereby acknowledged).

3.            Upon execution hereof, Vista agrees to pay to Northeast the entire
principal amount outstanding under the 12% collateralized notes, together with
interest (the "Notes") issued to private investors, by Northeast (the "Note
Investors"), being $75,000, plus interest, against the receipt from each
investor of a full and final release of each of Vista and their respective
officers, directors, employees and shareholders from any and all liability in
connection therewith and the release by the Note Investors of all claims to
the Vista Shares (as defined in section 8) held as collateral for the Notes. 
Northeast agrees to register any and all discharges under the PPSA necessary
in order to reflect the foregoing.

4.            Upon execution hereof, Vista agrees to pay a lump sum payment in
the amount of $50,000 to Northeast to assist it in carrying on its business
activities.  In addition to the foregoing, Vista agrees to pay $75,000 to
Northeast and $200,000 (the "Escrow Funds") to Grubner, Krauss, Barristers and
Solicitors (the "Escrow Agents") upon Vista completing its financing with
Paramount Capital or any other investor or lender, in a minimum aggregate
gross amount of $2 million dollars, which it contemplates doing on or before
January 20, 1997.  (The parties acknowledge and agree that any equipment
leasing will not be considered part of any such Vista financing for purposes
of calculating the minimum aggregate gross amount of $2 million dollars).  The
$200,000 being remitted to the Escrow Agents shall be held by the Escrow
Agents and remitted by the Escrow Agents upon the following terms and
conditions:

a.            The Escrow Agents shall remit directly to Northeast's premises
lessor and equipment lessors to the extent that Escrow Funds are available, on
the first day of each month commencing in February, the amount of $25,000 to
assist Northeast in defraying the aforesaid expenses.  The Escrow Agents agree
to provide confirmation of such payment to Vista forthwith following
remittance thereof.

b.            The Escrow Agents shall release $50,000 to Northeast upon
Northeast delivering to the Escrow Agents, a final release of Northeast's
license of the Vista name as contemplated by paragraph 5 hereof.

Provided however that the Escrow Agents shall remit to Vista any amounts not
already advanced to Northeast pursuant to the terms hereof (with any interest
earned on such Escrow Funds which has not already been advanced to Northeast
pursuant to the terms hereof) at such time as Northeast has completed one or
more
<PAGE>
                                                           Page 3

financings in the aggregate gross minimum amount of $500,000 by way of debt or
equity.  Northeast agrees to use reasonable best efforts to complete such
financings as soon as possible.  In addition, the Escrow Agents shall remit to
Vista any Escrow Funds not already advanced to Northeast pursuant to the terms
hereof, upon:

  (i)     a direct or indirect change in control of Northeast; or 

  (ii)    the bankruptcy or commercial insolvency of Northeast;

  (iii)  Dr. Herzig opening, operating, being involved with, affiliated
with, lending his name to or becoming otherwise related to any of the
Corporations or firms listed on Schedule "A" attached or their successors,
save and except for Dr. Herzig continuing any previously established patient
referral relationships with 20/20 (now owned by TLC Laser Centers) and Clear
Vision.

Provided further, that the Escrow Agents shall return to Vista the $50,000
referred to in paragraph (b) hereof (without set-off), if Northeast fails to
deliver a release to the license agreement by the 1st day of July, 1997.

Provided further that upon execution hereof Vista shall deliver an irrevocable
direction to Paramount Capital directing Paramount Capital to remit to the
Escrow Agents and to Northeast the amounts payable pursuant to this paragraph
forthwith following it or its nominee having available the moneys it
contemplates raising on behalf of, or in connection with its offering or its
investment or its financing of Vista, in the aggregate minimum amount of $2
million dollars.  Vista shall forthwith cause Paramount Capital to acknowledge
receipt of the aforesaid irrevocable direction and Paramount Capital's
agreement to be bound for by the terms thereof.

5.            Northeast will agree to cease using the "Vista" name and
associated trademarks in connection with its business operations and shall
take the necessary steps to change the signage at its Toronto clinic on or
before July 1, 1997 and acknowledges that such name and trademark are the sole
property of Vista to utilize the name and trademarks as aforesaid.  Northeast
acknowledges that in the event of bankruptcy or a material breach of the
provisions hereof the license shall terminate.  Vista will be permitted to
advise creditors of Northeast, other than the equipment lessor and the
premises lessor, that it is no longer associated with Northeast.

6.            Vista will agree to forthwith cease using the name of Dr. Sheldon
Herzig and the reference to the Toronto clinic in its advertisements and
investor materials.  Vista will allow Northeast's representatives to speak
with a representative of Paramount Capital to ensure that it is understood
that neither Northeast nor Dr. Herzig is associated with Vista.  Northeast
agrees that a representative of Vista may participate in such meeting or
discussion.

7.            Vista will remain as guarantor under the premises lease respecting
the Northeast Toronto clinic located at the Collonade and under the equipment
<PAGE>
                                                           Page 4

lease for the equipment located at that clinic, provided that Northeast shall
use reasonable best efforts to amend such leases to provide that at such time
as Northeast raises capital in the amount of $2 million or more or in the
event of a direct or indirect change in control of Northeast, Vista's
guarantee on such leases shall be unconditionally released (For purposes of
this agreement "control" shall have the meaning set out in section 1(5) of the
Ontario Business Corporations Act.  Cherry Sharrer, Dr. Sheldon Herzig and
Cherry Development Corporation represent and warrant that Northeast is
presently jointly controlled by Cherry Development Corporation and Shefa
Enterprises Limited and the parties agree that a direct or indirect change in
control of either Cherry Development Corporation or Shefa Enterprises Limited,
other than a change in favour of Cherry Sharrer or Sheldon Herzig, shall be
considered a change in control of Northeast.  In the event that despite the
exercise of such reasonable best efforts, the lessors under such leases are
unwilling to make such amendments, Northeast will provide a secured indemnity
to hold Vista harmless under such guarantees at such time as it raises capital
in the amount of $2 million or more or in the event of a direct or indirect
change in control of Northeast.  Northeast shall also agree to provide Vista
with the right to assume the leases in the event of an unremedied default, and
following 15 days written notice thereof to Northeast, and shall agree to
provide immediate written notice of any defaults thereunder and shall agree
not to move such equipment outside the Metropolitan Toronto clinic without the
prior consent of Vista.  Vista's guarantee hereunder shall only operate for
the initial term of such leases and shall not continue upon renewal. 
Northeast agrees to provide a quarterly statement to Vista to the effect that
there has been no direct or indirect change of control in Northeast or Cherry
Development Corporation or Shefa Enterprises Limited and that the lease is not
in default.  Provided that following July 1, 1997, Northeast shall have no
obligation to provide any information other than in respect to the status of
the lease.  Provided that Vista may confirm the status of the leases with the
lessors directly from time to time.  So long as Vista has not been released
from such leases, Northeast shall not assign or sublet the equipment or the
premises under such leases without the consent of Vista, such consent not to
be unreasonably withheld or delayed.

8.            The 450,000 shares of common stock in the capital of Vista (the
"Vista Shares") being the property of Northeast shall be assigned to Vista
forthwith following the deposit with the Escrow Agents of all funds
contemplated by paragraphs 4 and 9 hereof. The Vista Shares shall be assigned
to Vista free and clear of any encumbrances or liens. Upon the execution
hereof, Northeast agrees to deposit the Vista shares with the Escrow Agents to
ensure that they are not assigned or encumbered in contravention of this
agreement. Should Vista fail to advance the sums required pursuant to section
4 and 9 hereof, the Escrow Agents shall return the Vista Shares to Northeast.

9.            Vista shall concurrently with the payments to the Escrow Agents of
the amounts referred to in paragraph 4 hereof, also remit to the Escrow Agents
the amount of $50,000 which shall be made available to Northeast, by the
Escrow Agents to assist Northeast in the preparation of documentation and the
raising of capital, whether by way of financing or equity.
<PAGE>
                                                           Page 5     

It is understood that $25,000 of the amount shall be advanced to third party
professionals assisting in the raising of capital, at the inception of that
process and the balance of which shall be advanced only at such time as the
Escrow Agents are reasonably satisfied that sufficient investors have been
procured to make completion of the financing in the aggregate gross amount of
$500,000 a reasonable likelihood.  At such time, the Escrow Agents shall
provide notice to Vista of such disbursement.

Northeast shall be obligated to repay this $50,000, without interest (except
in the event of default), to Vista upon the raising of capital, in aggregate,
of the gross amount of $500,000.  Northeast agrees to provide a general
security agreement and promissory note and general security agreement shall be
subordinate to any and all third party financing.

The Escrow Agents shall provide Vista with a quarterly accounting of the
disbursement of escrow funds.  In the event that there is a legitimate
material dispute with respect to the provisions hereof or the disbursements of
the Escrow Funds, the Escrow Agents are hereby irrevocably directed to deposit
such Escrow Funds with a Court of competent jurisdiction pending the
resolution of the dispute.  In such event, the Escrow Agents shall deliver
written notice to all parties.

10.           Vista does hereby release and hold Northeast and its shareholders
and officers harmless and forever discharged from any liability in connection
with any funds advanced or contributed to Northeast on any other agreement. 
Northeast does hereby release and hold Vista and its directors, officers,
employees and shareholders harmless and forever discharged from any liability
in connection with any agreement or instrument entered into in furtherance of
Northeast's business.  All other agreements including without limitation the
Option Agreement and the Consulting Agreement entered into between the parties
hereto shall automatically terminate and be of no further force and effect.

The parties shall exchange full and final releases and shall agree to keep the
terms of this agreement confidential, except as set forth above.

All amounts stated in the agreement are stated in United States currency. In
addition, each of Northeast and Vista and their respective principals agree
that they will take no steps to interfere with or frustrate the financing
efforts of the other and shall take no steps and make no comments to third
parties which would reasonably have this result or disparage the reputation of
the other.

11.           The parties hereto acknowledge that any promotional or marketing
material, logos, designs, brochures, trademarks, stationary, advertising, or
any other material of a related nature shall, remain the property of Vista but
shall be licensed to Northeast (on a non-assignable basis) for a period of 21
years (with an automatic renewal every 21 years) within the Greater Toronto
Area (for purposes of this agreement Greater Toronto Area means all Canadian
territory within a radius of 100 kilometres of the Vista Eye Institute at 131
Bloor Street, Toronto.  For greater certainty the parties acknowledge and
agree that the Greater Toronto Area does not include Windsor, Ontario).  Such
licence shall
<PAGE>
                                                           Page 6

terminate upon the bankruptcy or insolvency of Northeast or upon a material
breach of this agreement by Northeast or the Northeast Parties. The parties
further acknowledge and agree that the copy and text of such promotional
materials may be used by both Vista and Northeast in their respective areas
provided that Vista's use of such copy and text will not include any reference
to Dr. Herzig and, subject to the licence agreement set out in section 1
hereof, Northeast's use of such copy and text shall not use the word "Vista"
or associated logo).  Notwithstanding the foregoing, Vista shall be entitled
to provide such promotional material to potential investors within the Greater
Toronto Area as part of providing a prospectus or offering memorandum (and
associated materials) to such potential investors.  In consideration of the
foregoing, Vista acknowledges that it shall not open or operate or be involved
with or affiliated with or otherwise related to a laser vision correction
center or any center that provides laser vision correction services under or
using the name "Vista" in any manner within the Greater Toronto Area for a
period of at least two years following execution of this agreement. 
Notwithstanding the foregoing, such requirement that Vista not use the "Vista
" name within the Greater Toronto Area shall cease immediately upon:

  (a)   a direct or indirect change in control of Northeast;

  (b)   the bankruptcy or commercial insolvency of Northeast;

  (c)   a material breach by Northeast, Dr. Sheldon Herzig, Cherry Sharrer
        or Cherry Development Corporation of any of the terms of this
        agreement;

  (d)   Dr. Sheldon Herzig opening, operating, becoming involved with,
        affiliated with, lending his name to or becoming otherwise related
        to or with any of the corporations or firms listed on Schedule "A"
        attached or their successors save and except for Dr. Herzig
        continuing any previously established patient referral
        relationships with 20/20 (now owned by TLC Laser Centers) and
        Clear Vision; or

  (e)   Dr. Herzig's soliciting any physician, who as of the date of such
        solicitation has entered into a written agreement with Vista for
        some form of association with Vista, to leave or break his or her
        association with Vista.

        Notwithstanding a material breach of this agreement, Vista shall
continue to have the right to use the "Vista" name outside the Greater Toronto
Area.

12.           This agreement may be executed in one or more counterparts and by
facsimile transmission.  Each counterpart shall be deemed an original and all
counterparts shall constitute one and the same instrument.  It shall not be
necessary that any single counterpart be executed by all parties, as long as
at least one counterpart is executed by each party.

13.           This agreement shall be governed by and interpreted in accordance
<PAGE>
                                                           Page 7

with the laws of the province of Ontario, Canada.

14.           The parties hereto agree to execute such further documents and
assurances as may be necessary to implement the terms and provisions of this
agreement. Time shall be of the essence of this agreement and of every part
hereof. This agreement shall be binding upon the parties hereto and any
successors, assigns, affiliated or related parties, and any subsidiaries
thereof (as all of those terms are defined in the Income Tax Act of Canada).

15.           Should any party to this agreement be entitled to certain rights
or to take certain actions upon a "material breach" by one of the other
parties to this agreement, the party alleging such material breach shall not
be entitled to such rights or to take such actions until the issue has been
arbitrated and the arbitrator has determined that there has been a material
breach.  The parties acknowledge and agree that should one party allege that
there has been a material breach by one of the other parties to this
agreement, the issue shall be determined by arbitration pursuant to the
Arbitration Act, Ontario.  The arbitrator shall be appointed by a court of
competent jurisdiction.  The costs of such arbitration shall be as awarded by
the arbitrator.  The decision of the arbitrator shall be final and shall not
be subject to appeal.

16.           Each party hereto acknowledges that he, she, or it understands the
provisions hereof and has been advised to obtain independent legal advice.

        (i)   Net rentable area on single tenancy floor shall be
  determined by measuring from the inside surface of the glass on the
  exterior walls to the inside surface of the glass on the opposite
  exterior wall and shall include all areas within the outside walls
  excluding vertical penetrations such as building stairs, fire towers,
  elevator shafts, flues, vents, stacks, pipe shafts, and vertical ducts. 
  Vertical penetrations which are for the specific use of Tenant, such as
  special stairs or elevator shall be included as Net Rentable Area.  No
  deductions from Net Rentable Area will be made for columns or
  projections necessary to support the Building and/or other common areas
  used to benefit Tenant;


                                    -2-

        (ii)  Net Rentable Area for partial floors shall include all space
  within the demised premises (measured from the midpoint of the demising
  walls and, in the case of exterior walls, measured as set forth in (i)
  above, excluding vertical penetrations such as building stairs, fire
  towers, elevator shafts, flues, vents, stacks, pipe shafts, and vertical
  ducts, plus Tenant's proportionate share (excluding single tenancy
  floors) of the common areas within the Building such as lobbies,
  corridors, toilet and mechanical rooms, telephone and electrical
  closets, and service areas in the  Building.  Vertical penetrations
  which are for the specific use of the Tenant such as special stairs or
  elevators shall be included as Net Rentable Area.

        (iii) In determining the Net Rentable Area of the Building, all
  common areas within the Building and all areas devoted to Tenant storage
  outside of the Building shall be included.  In computing the Net
  Rentable Area of the Premises, there shall be included a pro rate share
  of all Common Areas within the Building and a pro rata share of any
  storage areas available for Tenants.

2.      PREMISES

        For and in consideration of the agreement of the Tenant to pay the

4.     LEASE TERM

  4.1   The date specified in Section 1 upon which the Lease Term shall
commence is the Commencement Date.  In the event Landlord is, for any reason
other than delay  principally caused by or attributable to Tenant,its agents
or contractors, unable to deliver possession of the premises to Tenant on the
Commencement Date, this Lease shall nevertheless continue in full force and
effect and Landlord shall have no liability as a consequence of any such
delay; provided, however, that rents otherwise payable hereunder shall abate
for the period between the Commencement Date an  the date of substantial
completion of any improvements to the premises in accordance with Section 3
above and tender of the premises by Landlord for Tenant's occupancy
("Possession Date").   There shall be no abatement of rent if delivery of
possession of the premises by Landlord to Tenant is principally caused by or
attributable to Tenant, its agents or contractors, and in such event the
Commencement Date shall be deemed the Possession Date, and Landlord shall
deliver the Premises to Tenant as soon thereafter as is reasonably
practicable.

  4.2   If the Possession Date occurs on a date subsequent to the
Commencement Date, the parties shall execute and initial the Memorandum of
Possession Date set forth above.  In the event Landlord shall deliver and
Tenant shall accept possession of the Premises prior to the Commencement Date,
the provisions of this Lease shall be applicable, and all rents shall be
payable during such period prior to the Commencement Date, but the
Commencement Date shall not otherwise be affected by such prior possession.
All rents payable hereunder for a fractional calendar month shall be prorated
on a per diem basis, calculated on the basis of a thirty (30) day month.

5.      RENTAL PAYMENTS

  5.1   Throughout the Lease Term, Tenant agrees to pay Landlord at such
place as Landlord may designate, without prior demand therefore and without
any deduction or set-off whatsoever, in lawful money of the United States of
America:

        (a)   The Minimum Monthly Rent, in advance, on or before the first
day of each calendar month during the Lease Term.  Upon execution of this
Lease, Tenant agrees to pay Landlord the Minimum Monthly Rent for the 1st full
calendar month of the Lease Term; and, 

        (b)   All excise, sales, use, rental, and/or transaction privilege
taxes levied or imposed, or hereafter levied or imposed, against or on account
of any or all amounts payable hereunder by Tenant or the receipt thereof by
Landlord (except Landlord's income

                                    -4-
<PAGE>
if any), said taxes to be paid together with the Minimum Monthly Rent, or as
the Landlord may designate.

  5.2   Tenant also agrees to pay, as additional rent, the amounts
required by Section 7 hereof.


6.      SECURITY DEPOSIT 

  6.1   Upon occupancy of the Premises Tenant shall deposit with Landlord
the Security Deposit, which sum shall be held by Landlord, without obligation
for interest, as security for the performance of Tenant's covenants and
obligations under this Lease.  The Security Deposit is not an advance rental
deposit nor a measure of Landlord's damages in the event of Tenant's default.
Upon the occurrence of any event of default by Tenant, Landlord may, from time
to time, without prejudice to any other remedy provided herein or by law or
equity, use and apply all or any portion of the Security Deposit to the extent
necessary to remedy any arrears of rent or other expense or liability caused
by such event of default.  Tenant shall pay to Landlord on demand any amount
so applied by Landlord in order to restore the Security Deposit to its
original amount.

  6.2   Prior to the time when Tenant is entitled to the return of the
Security Deposit, Landlord shall not be required to segregate such deposit
from other funds of Landlord,  and may use the Security Deposit for such
purposes as Landlord may determine.  The Security Deposit shall be returned to
Tenant (or, at Landlord's sole election without liability to or recourse by
Tenant, to the last approved assignee, if any, of Tenant's interest hereunder) 
upon the expiration of the Lease Term and delivery of possession of the
Premises to  Landlord, if at such time, Tenant has performed and complied with
all of the terms, covenants and conditions of this  Lease.  In the event of
the termination of Landlord's interest in this Lease, Landlord shall transfer
said deposit to Landlord's successor in interest, whereupon Tenant shall
release Landlord from all liability for the return of such deposit or the
accounting therefore.

7.      BUILDING OPERATING COSTS

  7.1   For purposes hereof:

        (a)   "Building Operating Costs" shall mean those costs and
expenses incurred or paid by Landlord or Landlord's agents with respect to the
operation and maintenance of the Building which, in accordance with the
accounting method used by Landlord on a consistent basis, as applied to the  
operation and maintenance of the Building, are properly chargeable to the
operation and maintenance of the Building, including, without limitation:


                                    -5-
<PAGE>
              (i)   all real property taxes and special assessments levied
upon the Building and all appurtenant real property and improvements of
Landlord and all personal property taxes levied on equipment, fixtures, and
other property of Landlord located in the Building and used in connection with
the operation thereof;

              (ii)  all labor costs involved in the normal
operation and maintenance of the Building;

              (iii) costs of utilities, telephone service to the building
and refuse removal;

              (iv)  costs of insurance maintained by Landlord with respect
to the Building and Landlord's personal property used in connection therewith;

              (v)   costs of janitorial, window cleaning and other
cleaning contracts and services;

              (vi)  costs relating to the operation and maintenance of  
all parking areas, service areas, walkways and landscaping, and any common
areas within or appurtenant to the Building;

              (vii) a management fee, not to exceed prevailing market
rates.

Building Operating Costs shall not include roof repairs or replacement, the
costs of major structural repairs or extraordinary maintenance, expenses for
which Landlord is reimbursed or indemnified (whether by an insurer, condemnor,
tenant or otherwise), interest or amortization payments on any encumbrance, or
overhead and administrative costs by Landlord not directly incurred in the
operation and maintenance of the Building, except as may be otherwise
specifically set forth herein.

        (b)   "Fixed Operating Costs" shall mean all Building Operating
Costs which would have been incurred by Landlord with respect to the Building
regardless of whether Tenant or any other tenants occupied the Building. 
"Variable Operating Costs" shall mean all Building Operating Costs which are
not Fixed Operating Costs.   Building Operating Costs shall be characterized
as Fixed Operating Costs or Variable Operating Costs by Landlord's accountant
in accordance with principles formulated by Landlord's accountant in
accordance with this provision and consistently applied.  Such
characterization of Building Operating Costs shall be conclusive and binding
on Tenant.

        (c)   "Landlord's Contribution" shall mean that amount which shall
equal, with respect to each calendar year, the product

                                    -6-
<PAGE>
 
of (i) six dollars ($6.00),  (ii) the Net Rentable Area of the Building.  
Landlord shall, with respect to each calendar year, pay Building Operating
Costs in an amount not to exceed the Landlord's Contribution for such calendar
year.   The Landlord's Contribution shall be allocated first to Fixed
Operating Costs and then to Variable Operating Costs.
 
        (d)   "Reimbursement Amount" shall mean that amount, if any, by 
which the actual Building Operating Costs incurred by Landlord in any given
calendar year exceed the Landlord's contribution for such calendar year.

        (e)   "Tenant's Variable Share" shall mean that fraction, the
numerator of which is the Net Rentable Area of the Premises occupied by the
Tenant during each calendar year and the denominator of which is the Net
Rentable Area of the Building, as such fraction shall be determined by the
Landlord or its agents.  For purposes of computing the fraction described in
the preceding sentence, the Landlord may compute the numerator and denominator
of such fraction by using a weighted average method selected by the Landlord
and consistently applied.   Consistent with a weighted average method,
adjustments may be made to  (i) the numerator of said fraction to reflect for
each calendar month in the relevant calendar year, the highest amount of Net
Rentable Area of the Premises occupied by the Tenant at any time during each
such calendar month;  and to  (ii) the denominator by taking the highest Net
Rentable Area of the Building.

  7.2   Landlord and Tenant hereby acknowledge that the Minimum Monthly
Rent provided for hereunder has been determined based upon the assumption that
the actual Building Operating Costs received by Landlord will approximate the
Landlord's Contribution.   Accordingly, Tenant hereby agrees to pay Landlord,
with respect to each calendar year, an amount equal to the sum of (i) Tenant's
proportionate Share of the amount, if any, by which the Fixed Operating
Expenses for such calendar year exceed Landlord's Contribution for such year,
plus (ii) Tenant's Variable Share of the amount, if any, by which the
Reimbursement Amount exceeds the amount of Variable Operating Costs described
in clause (i) above.  In computing the amounts under this Section 7.2, the
Landlord's Contribution shall be allocated as described in Section 7.l(c).

  7.3   The amount of payments to Landlord provided pursuant to Paragraph
5.2 above shall be computed annually on a calendar year basis, provided,
however, that Landlord may, prior to the beginning of any calendar year,
estimate the amount of such reimbursement to which the Landlord will be
entitled from Tenant for such calendar year and notify Tenant in writing of
such amount.  If Landlord provides Tenant with such notification, Tenant shall
pay to Landlord on a monthly basis together with the Minimum Monthly Rent an
amount which shall equal the quotient obtained by dividing the amount


                                    -7-
<PAGE>
stated in such notice by the number of payments of Minimum Monthly Rent that
Tenant is obligated to make pursuant to this Lease during the calendar year to
which the written notification relates.

  7.4   Unless delayed by causes beyond Landlord's control, not later than
March 31st of each year during the Lease Term (and the year immediately
following expiration of the Lease Term), Landlord shall provide Tenant with a
statement of:  (a) the Reimbursement Amount, (b) the portion of the
Reimbursement Amount for which Tenant is obligated pursuant to Section 7.2,
and (c) a statement showing the difference between the amounts paid by Tenant, 
if any, pursuant to Section 7.3, and the portion of the Reimbursement Amount
for which Tenant is obligated.  Tenant shall pay to Landlord any deficiency
disclosed by such statement, and any overage shall be credited by Landlord to
any other amounts owed by Tenant under this Lease or refunded to Tenant.  In
the event of the nonpayment of any amounts due hereunder, Landlord shall have
with respect thereto all rights and remedies herein provided in the event of
nonpayment of rent.

8.      TAXES ON PERSONAL PROPERTY

        Tenant shall pay prior to delinquency, all taxes levied upon
fixtures, furnishings, equipment, and all other personal property belonging to
Tenant and placed on the  Premises by Tenant.  In the event any of Tenant's
fixtures, furnishings, equipment and other personal property shall be assessed
and taxed with Landlord's real property, Tenant shall pay to Landlord its
share of such taxes within twenty (20) days after delivery to Tenant by
Landlord of a statement in writing setting forth the amount of such taxes
applicable to Tenant's property.  When possible, Tenant shall cause said
fixtures, furnishings, equipment and other personal property to be assessed
and billed separately from the real property of Landlord.

9.      ALTERATIONS, ADDITIONS AND IMPROVEMENTS

  9.1   Following the completion of the initial improvements of the
Premises in accordance with the provisions of Section 3 hereof, Tenant shall
not make, or allow to be made, any alterations, additions or improvements to
the Premises without the prior written consent of Landlord, which shall not be
unreasonably withheld.

  9.2   (a)   Any approved alterations, additions or improvements to the
Premises shall be surrendered by Tenant as part of the Premises, without
disturbance or injury, upon the expiration or earlier termination of this
Lease, unless Landlord designates in writing that such alterations, additions

or earlier termination of this Lease, Tenant shall, at its sole cost and

                                    -8-

expense, remove any such alterations, additions or improvements made by Tenant
and designated by Landlord for removal, and restore the Premises to their
original condition, normal wear and tear excepted.

        (b)   In the event of any injury or damage to the Premises
resulting from the removal by Tenant of any alterations, additions or
improvements, or fixtures, equipment and furnishings pursuant hereto, Tenant
shall promptly repair the same, at its sole cost and expense, in a good and
workmanlike manner, or at Landlord's election, shall pay to landlord an amount
sufficient for Landlord to repair same or to compensate Landlord for such
injury or damage to the Premises.

  9.3   Tenant shall keep the Premises and the Building free from any

any use or occupancy of the Premises, such statement shall  be conclusive upon
Tenant, subject to Paragraph 32, and Tenant shall be liable for any increase
and shall reimburse Landlord on demand therefor.  No vending machines shall be

Landlord.

11.     CARE OF PREMISES

  12.2  Tenant shall be entitled to park in common with other tenants of
the Building in those areas designated for nonreserved tenant parking.  
Tenant agrees to cooperate with Landlord and other tenants in the use of the
Parking facilities.   Landlord reserves the right, in its absolute discretion,
to determine whether parking facilities are becoming crowded and, in such
event, to allocate parking spaces among Tenant and other tenants.  No storage
of vehicles or parking for more than seventy-two (72) hours shall be allowed
without Landlord's prior written consent.  Tenant and its employees will
refrain from parking in areas designated by Landlord from time to time as
visitor parking.  Landlord reserves the right to remove or tow any vehicles
which are or appear to be illegally or improperly parked, or abandoned, and
Tenant agrees to indemnify Landlord from and against any and all claims as a
result of such removal or towing, said indemnification to be in Tenant's
Proportionate Share (as described herein) to the full indemnification
required.

13.     INSURANCE

the Premises and all of Tenant's personal property, inventory, decorations,
trade fixtures, furnishings, equipment and other contents in the Premises.

        (b)   All such policies of insurance shall name both Landlord and
Tenant as insureds (and/or such other party or parties as Landlord may

  13.2  Notwithstanding the provisions of this Section 13, Tenant and
Landlord each hereby waive any and all rights of recovery against the other,
or against the officers, employees, agents and representatives of the other,
for loss of or damage to such waiving party or its property or the property of
others under its control to the extent that such loss or damage is  insured

        (d)   Elevator service; and

        (e)   All water service to the Building, subject to the imposition
of mandatory use or quantity limitations by applicable governmental agencies

  14.2  Tenant shall not, without the written consent of Landlord, use any
apparatus or device in the Premises other than those business machines
referred to above, that will in any way increase the amount of electricity or
water usually furnished or supplied for use of the Premises as general office
space, or that will materially affect the temperature otherwise maintained by
the air conditioning system.  Landlord may cause an electric current or water
meter to be installed in the Premises to measure the amount of electric
current or water consumed for any such additional use, and shall have the
right to install any machinery and equipment which Landlord reasonably deems
necessary to restore temperature balance, including, without limitation,
modifications to the standard air


                                    -11-

cost of operation and maintenance occasioned thereby to be paid by Tenant.

  14.3  If Landlord provides electrical power in excess of normal office
usage levels in order for Tenant to operate any heat generating data
processing or other equipment requiring extra electrical power, and the
Premises are not separately metered, or if Landlord provides any other utility

15.     MAINTENANCE AND REPAIR

  15.1  Subject to the provisions of Section 14 and Section 17 hereof,

be made by Landlord and perform all redecorating, remodeling, alterations, and
painting required by Tenant and permitted by Landlord during the Lease Term.  
Tenant shall pay for any repairs to the Premises or the Building resulting
from any misuse or neglect of Tenant, or its employees or invitees (as, by way

                                    -12-
<PAGE>

breach or default in the performance of any obligation of Tenant under this
Lease, or arising from any act or negligence of Tenant, or of its agents or
employees, and from all costs, attorneys' fees, expenses and liabilities
incurred by Landlord as a result of any such claim or action or proceeding
brought thereon.  The foregoing shall not be deemed to release or waive any of
Tenant's rights or remedies against Landlord for damage or injuries caused to
persons or property resulting from Landlord's negligence or willful
misconduct.

  16.2  Landlord shall not be liable for injury to Tenant's loss of income
therefrom or for damage that may be by the person or property of Tenant, its
employees, invitees, customers, agents or contractors or any other tenant of
the Building or other person in or about the Premises, caused by or resulting
from fire, steam, electricity, gas, water or rain, which may leak or flow from
or into any part of the Premises, or from the breakage, leakage, obstruction
or other defects of the pipes, sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures, whether said damage or injury results from
conditions arising upon the Premises or upon other portions of the Building,
except to the extent such damage or injury is caused by Landlord's failure to
make necessary repairs for which it is responsible within a reasonable time
from the receipt of notice from Tenant of the necessity therefor.  Tenant
shall give immediate notice to Landlord in the event of fire or accident to or
defect in the Premises or the Building or any of its fixtures, appurtenances
or equipment, and shall cooperate with Landlord and the insurance carrier in

regulations, and Landlord shall not be liable for any other incidental or
consequential damages suffered or incurred by Tenant, its agents or employees
as a result thereof.  Landlord shall have a reasonable time, after receiving
written notice of any such violation from Tenant or any other party, to remedy
such violation.  The existence of any such violation and the necessary time to
correct same shall not constitute grounds for constructive eviction or breach
of any implied or express warranty, except to the extent such damage or injury
is caused by Landlord's failure to make necessary repairs for which it is
responsible within a reasonable time from the receipt of notice from Tenant of
the necessity therefor.

17.     DAMAGE OR DESTRUCTION

  17.1  In the event all or substantially all of the premises or the
Building are destroyed by fire or any other casualty so as become
untenantable, Landlord may elect to terminate this Lease as of the date of
such damage or destruction, by notice to Tenant within thirty (30) days
thereafter.   In the alternative, Landlord in its sole discretion may elect to
repair or rebuild the Premises or the Building as promptly as possible at the
expense of Landlord.  In the event Landlord elects to so repair or rebuild but
fails to substantially complete such repair or rebuilding within one hundred
eighty (180) days after such damage or destruction occurs (extended for delays
due to causes beyond the control of Landlord),  then either party may
thereupon terminate this Lease by notice to the other party no later than ten
(10) days after expiration of said one hundred eighty (180) day period or
extension thereof.  If the Premises or the Building shall be partially damaged
or injured by fire or other casualty, Landlord shall promptly repair or
rebuild the same.   In connection with any repair or rebuilding by Landlord
hereunder, should there be a substantial interference with Tenant's use of the
Premises, Tenant shall be entitled to a proportionate reduction of Minimum
Monthly Rent while such repairs are being made, be based upon the extent other
effects resulting from the casualty shall interfere with the business
conducted by Tenant in the Premises; provided, however, that rent shall not
abate if such damage was caused by Tenant, its agents, employees and invitees,
and further provided that Tenant shall not be permitted to terminate this
Lease except as set forth herein.

  17.2  Notwithstanding anything contained herein to the contrary, in the
event the holder of any indebtedness secured by a mortgage or deed of trust
covering the Premises requires that the insurance proceeds be applied to such
indebtedness, then Landlord shall have the right to terminate this Lease by
delivering written notice of termination to Tenant, whereupon all rights and
obligations hereunder shall cease and terminate.   No damages, compensation or
claim shall be payable by Landlord to Tenant for inconvenience, loss of
business or annoyance from any repair or rebuilding of any portion of the
Premises or the Building or from the termination of this Lease pursuant to
this Section 17.

18.     CONDEMNATION

        If all or any part of the Premises or the Building shall be taken
for public or quasi-public use under any governmental law, ordinance or
regulation, or by right of eminent domain, or consent sale in lieu thereof,
and such taking renders the Premises untenantable for Tenant's business, this
Lease shall terminate as of the date of transfer of possession of the Premises

thereto, or suffer any person (except the agents and servants of Tenant) to

obtaining the written consent of Landlord, which consent may not be
unreasonably withheld.

  20.2  Any consent obtained hereunder to one such assignment, subletting, 
occupation, or use by any other person shall not be deemed to be a consent to
any subsequent assignment, subletting, occupation or use by another person, 
nor shall such consent be deemed a waiver by Landlord of Landlord's right to
withhold its consent as provided hereunder as to any subsequent assignment,
subletting,  occupation or use by another person.

  20.3  Any assignment or subletting permitted hereunder shall expressly
provide, and shall be permitted solely upon the condition that, the assignee

estate;  and that each such assignee or sublessee shall be fully bound to

encumbrance of this Lease, without the consent required and described herein,
shall be void, and not voidable, and shall at the sole option of Landlord
terminate this Lease.

  20.5  This Lease shall not, nor shall any interest therein, be
assignable as to any interest of Landlord by operation of any law, without the
written consent of Landlord, which consent may be withheld for any reason in
Landlord's sole discretion.

  20.6  Tenant shall pay Landlord's reasonable attorneys' fees in
connection with giving the consent required and described herein.

  20.7  If Tenant or any assignee or sublessee assigns this Lease sublets

portion of the Premises is sublet) greater than that paid to Landlord
hereunder, such excess shall be paid to Landlord as received.

21.     ESTOPPEL CERTIFICATE

  21.1  Tenant shall within twenty (20) days following any written request
from Landlord, execute, acknowledge and deliver to Landlord a written
statement certifying:  (a) that this Lease is in full  force and effect and
stating the nature of any modification hereto;  (b) the dates to which the
rentals and other charges are paid in advance, if any;  (c) there are not, to
Tenant's knowledge, any defaults on the part of Landlord hereunder, or
specifying such defaults if they are claimed;  and (d) such other matters as
may reasonably be requested by Landlord.  Any such statement may be relied
upon by any prospective purchaser or encumbrancer of all or any portion of the
Building or the Premises.  Tenant's failure to deliver such statement within
such time shall be conclusive upon Tenant (a) that this Lease is in full force
and effect, without modification except as may be represented by Landlord, (b)
that there are no uncured defaults in Landlord's performance, and (c) that not
more than one month's rent has been paid in advance.

  21.2  Prior to execution of this Lease, or if Landlord desires to

to deliver to Landlord or to any lender designated by Landlord, such financial
statements of Tenant as may be reasonably required by landlord or such lender,
to be received by Landlord in confidence and used only for the purpose of
evaluating Tenant's financial condition.  In addition, Tenant will not
unreasonably withhold its consent to any modifications to this Lease required
as a condition to such financing;  provided, however, that such modifications
do not increase the obligations of Tenant hereunder or materially adversely
affect the leasehold interest hereby created.

22.   DEFAULT OF TENANT

  22.1  If Tenant should fail to pay any part of the rentals herein
provided, or any other sum required by this Lease to be paid to Landlord at
the time or in the manner provided herein, for a period of twenty (20) days
after receipt by Tenant of written notice from Landlord, or if default should
be made in any of the other covenants, terms or provisions to be performed by
Tenant hereunder and such default should continue for a period of forty-five
(45) days following receipt of written notice thereof from Landlord to Tenant,
or should Tenant's interest herein be terminated or assigned by operation of
law or otherwise, including, without limitation, the filing of a petition by
or against Tenant (or any member of Tenant if Tenant is a partnership or joint
venture) under any insolvency or bankruptcy act, or should Tenant make a
general assignment for the benefit of creditors, or if Tenant should become
insolvent, or if Tenant should vacate or abandon the Premises, Landlord shall
have all rights and remedies it may have hereunder or at law or in equity.

  22.2  In the event Landlord shall fail to receive any installment of
rent or any other sum due hereunder within ten (10) days after such payment is
due, Tenant shall pay to Landlord a late charge in an amount equal to twenty
percent (20%) of such payment;  and the failure to pay such sums due and the
late charge as described herein, within twenty (20) days after written demand
therefor shall be an event of default hereunder.  The provision for such late
charge shall be in addition to all of Landlord's other rights and remedies
hereunder or at law, and shall not be construed as liquidated damages or as
limiting Landlord's remedies in any manner.

  22.3  No act or conduct of Landlord, whether consisting of the
acceptance of the keys to the Premises, or otherwise, shall be deemed to be or
constitute an acceptance of the surrender of the Premises by Landlord prior to
the expiration of the term hereof, and such acceptance by Landlord of
surrender by Tenant shall only be effected, and must be evidenced, by written
acknowledgment of acceptance of surrender signed by Landlord.  In the event
the Premises are relet at a rental which exceeds that owing from Tenant
herein, Tenant expressly agrees that Tenant, its successors, assigns and
representatives have no claim to or interest in the said profit, and that the
said profit is properly owing solely to Landlord as Landlord's agreed, stated
and liquidated fees, costs, expenses and compensation incurred or owing as a
result of Landlord's efforts in connection with the reletting of the leased
premises to mitigate Tenant's damages as a result of Tenant's default, but do
not constitute Landlord's liquidated damages of Tenant's whole default.

  This Exchange Agreement ("Agreement") is made as of October 1, 1996 by
and between Vista Laser Centers Of The Southwest, Inc., a Nevada corporation
(the "Company"), and Vista Technologies, Inc., a Nevada corporation ("Vista
Tech").

                                 RECITALS

  WHEREAS, Vista Tech has received an assignment from Pharma Patch PLC of
the Company's 12% Secured Convertible Promissory Note in the principal amount
of $100,000 (the "Note");

  WHEREAS, the Company desires to exchange with Vista Tech an aggregate of
100,000 shares of the Company's Common Stock ("Common Stock") in consideration
for the Note and the release of the Company's obligations under, and the
cancellation of the indebtedness evidenced by, the Note.

  NOW, THEREFORE, the Company and Vista Tech hereby agree as
follows:

  1.    EXCHANGE.   On this date and subject to the terms and conditions
of this Agreement, the Company hereby exchanges an aggregate of 100,000 shares
of Common Stock  (the "Shares") in consideration for the Note and Vista hereby
irrevocably and forever releases the Company from the Company's obligations
under, and cancels the indebtedness evidenced by the Note.  The term
"Securities" refers to the Shares purchased under this Agreement and includes
all securities received (a) in replacement of the Shares, (b) as a result of
stock dividends or stock splits in respect of the Shares, and  (c) all
securities or property received in replacement of the Shares in a
recapitalization, merger, reorganization or the like.

  2.    REPRESENTATIONS OF VISTA TECH.   Vista Tech represents and
warrants to the Company that: 

        (a)   Vista Tech is acquiring the Securities for Vista
Tech's own account for investment purposes only and not with a view to, or for
sale in connection with, a distribution of the Securities within the meaning
of the Securities Act of 1933, as amended (the "1933 Act").

        (b)   Vista Tech has no present intention of selling or otherwise
disposing of all or any portion of the Securities.

        (c)   Vista Tech has had access to all information regarding the
Company and its present and prospective business, assets, liabilities and
financial condition that Vista Tech reasonably considers important in making
the decision to acquire

                                   - 1 -
<PAGE>
the Securities, and Vista Tech has had ample opportunity to ask questions of
the Company's representatives concerning such matters and this investment.

        (d)   Vista Tech is fully aware of  (i) the highly speculative
nature of the investment in the Securities;  (ii) the financial hazards
involved;  (iii) the lack of liquidity of the securities and the restrictions
on transferability of the Securities;  and (iv) the qualifications and
backgrounds of the principals of the Company.

        (e)   Vista Tech is capable of evaluating the merits and risks of
this investment, has the ability to protect Vista Tech's own interests in this
transaction and is financially capable of bearing a total loss of this
investment.

        (f)   At no time was Vista Tech presented with or solicited by any
publicly issued or circulated newspaper, mail, radio or television, or any
other form of general advertising in connection with its acquisition of the
Securities.

        (g)  Vista Tech has been advised that the acquisition of the
Securities hereunder may have adverse tax effects upon Vista Tech.  Vista Tech
is not relying upon the Company or its Legal counsel and has consulted with
Vista Tech's own tax advisors in this regard.

  3.    COMPLIANCE WITH FEDERAL AND STATE SECURITIES LAWS.   Vista Tech
understands and acknowledges that, in reliance upon the representations and
warranties made by Vista Tech herein, the Securities have not been registered
with the Securities and Exchange Commission ("SEC") under the 1933 Act or the
laws of any state, but have been issued under an exemption or exemptions from
registration requirements of the 1933 Act and applicable state law which
impose certain restrictions on Vista Tech's ability to transfer the
Securities.

        (a)   RESTRICTIONS ON TRANSFER.   Vista Tech understands that 
Vista Tech may not transfer any Securities unless such Securities are
registered under the 1933 Act and any applicable state securities laws or
unless, in the opinion of counsel to the Company, an exemption from such
registration is available.  Vista Tech understands that only the Company may
file a registration statement with the SEC or any state and that the Company
is under no obligation to do so with respect to the Securities.  Vista Tech
has also been advised that an exemption from registration may not be available
or may not permit Vista Tech to transfer all or any of the Securities in the
amounts or at the times proposed by Vista Tech.

        (b)   RULE 144.   In addition, Vista Tech has been advised that
SEC Rule 144 promulgated under the 1933 Act, which permits

                                   - 2 -

to Vista Tech.

  4.    RIGHTS AS SHAREHOLDER.   Subject to the terms and conditions of

  AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF

  RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES
  LAWS.

        (b)   STOP-TRANSFER INSTRUCTIONS.   Vista Tech agrees that, in
order to ensure compliance with the restrictions referred to herein, the
Company may issue appropriate "stop-transfer" instructions to its transfer
agent, if any, and that, if the Company transfers its own securities, it may
make appropriate notations to the same effect in its own records.

        (c)   REFUSAL TO TRANSFER.    The Company will  not be required
(i} to transfer on its books any Securities that have been sold or otherwise
transferred in violation of any of the provisions of this Agreement or (ii) to
treat as owner of such Securities or to accord the right to vote or pay
dividends to any purchaser or other transferee to whom such Securities have
been so transferred.

        (d)   MARKET STANDOFF AGREEMENT.   Vista Tech agrees in connection
with any registration of the Company's securities that, upon the request of
the Company or the underwriters managing any public offering of the Company's
securities, Vista Tech will not


                                   - 3 -

sell or otherwise dispose of any Securities without the prior written consent
of the Company or such underwriters, as the case may be, for such period of
time after the effective date of such registration and subject to all
restrictions as the Company or the underwriters may specify for
employee-shareholders generally.

  6.    COMPLIANCE WITH LAWS AND REGULATIONS.   The issuance and transfer
of the Securities hereunder will be subject to and conditioned upon compliance
by the Company and Vista Tech with all applicable state and federal laws and
regulations and with all applicable requirements of any stock exchange on
which the Company's Common Stock may be listed at the time of such issuance
and transfer.

  7.    SUCCESSORS AND ASSIGNS.   This Agreement will be binding upon and
inure to the benefit of the successors and assigns of the Company.  Subject to
the restrictions on transfer herein set forth, this Agreement will be binding
upon Vista Tech and Vista Tech's successors and assigns.

  8.    INTERPRETATION.   Any dispute regarding the interpretation of this
Agreement will be submitted by Vista Tech or by the Company forthwith to the
Company's Board of Directors, which will review such dispute at its next
regular meeting.  The resolution of such a dispute by the Board will be final
and binding on the Company and on Vista Tech.

  9.    GOVERNING LAW; SEVERABILITY.   This Agreement will be governed by

provision will be enforced to the maximum extent possible and the other
provisions will remain effective and enforceable.

given in writing and will be deemed effectively given upon personal delivery
or upon deposit in the United States mail by certified or registered  mail,

  11.   FURTHER INSTRUMENTS.   The parties agree to execute such further
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Agreement.
