Item 5.  OTHER EVENTS.

    On August 29, 1997, VISTA Information Solutions, Inc. (the "Company") 
issued 2,500 shares of Series E Convertible Preferred Stock ("Series E") and 
2,500 shares of Series F Convertible Preferred Stock ("Series F"), both with 
a par value of $0.01 per share, to Sirrom Capital Corporation d/b/a Tandem 
Capital ("Sirrom) at a stated value and purchase price of $1,000.00 per share 
for an aggregate gross purchase price of $5,000,000.00.  Sirrom shall be 
entitled to receive quarterly dividends of $30.00 per share which will 
increase by $5.00 per share for each year after August 31, 2002.  Shares of 
Series E are convertible into the Company's Common Stock at an initial 
conversion price of $2.75 per share.  If the Company does not successfully 
close a registered public offering of Common stock in which, (i) the gross 
proceeds of the offering are at least $15,000,000.00 and (ii) the offering 
price per share is greater that $4.00 (a "Qualified Offering"), the 
conversion price shall be adjusted to $2.00 per share.  Shares of Series F 
shall be convertible into Common Stock on or after the earlier of the closing 
of a Qualified Offering or July 1, 1998 at an initial conversion price of (i) 
75 percent of the offering price in a successfully closed Qualified Offering 
or  (ii) in the event the Qualified Offering is not closed prior to July 1, 
1998, 75 percent of the average closing bid price for the Common Stock for 
the 20 consecutive trading days prior to June 30, 1998. Series E stock may be 
redeemed, at the option of the Company, at any time, provided the average 
closing bid price of the Company's Common Stock for the 20 consecutive 
trading days preceding the date of the redemption notice exceeds 200 percent 
of the Series E conversion price.  Series F stock may be redeemed, at the 
option of the Company, at any time on or after June 30, 1998 provided the 
average closing bid price of the Company's Common Stock for the 20 
consecutive trading days preceding the date of the redemption notice exceeds 
200 percent of the Series F conversion price.

    The effect of the sale of the shares of Series E and Series F Preferred 
Stock increases the Company's shareholders' equity, on a pro forma basis, to 
approximately $2,525,685.  Attached hereto, marked Exhibit 99.1, is a Balance 
Sheet and Statement of Operations, as of July 31, 1997, giving pro forma 
effect to the issuance of the shares.  Actual and pro forma operating results 
for the seven months ended July 31, 1997 are not necessarily indicative of 
the financial position or the operating results that would have occurred at 
July 31, 1997 or that will be achieved for the year or any other period.  
These statements should be read in conjunction with the Company's Annual 
Report on Form 10-KSB for the year ended December 31, 1996 and the Company's 
Quarterly Reports on Form 10-QSB for the six months ended March 31, 1997 and 
for the quarter ended June 30, 1997. The increase in the Company's equity, as 
a result of the sale of these shares, will enable the Company to be in 
compliance with the capital requirements of NASDAQ, and thus remain listed on 
NASDAQ's SmallCap Market.

    The Company intends to use a portion of the net proceeds from the sale of
the above mentioned shares for working capital purposes and has used
approximately $2,800,000 of the proceeds to retire the 1996 and 1997 Secured
Promissory Notes to SIRROM Capital.  Payment of this indebtedness will cause the
Company to amortize the remaining value ascribed to warrants issued to SIRROM in
connection with the above mentioned Secured Promissory Notes.  The Company also
intends to use a portion of net proceeds to retire the remaining balance of the
Factoring Loan Agreement with Silicon Valley Bank.

     NOTES TO THE CONSOLIDATED PROFORMA FINANCIAL STATEMENTS FOR THE
                     SEVEN MONTHS ENDED JULY 31, 1997
                               (Unaudited)

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

    The unaudited ProForma Consolidated Balance Sheet has been prepared to 
reflect certain transactions as if the proceeds of the Preferred Stock 
Offering had been used to repay certain debt obligations on July 31, 1997. 
The unaudited ProForma Consolidated Statement of Operations has been 
prepared to reflect these transactions as if they occurred on January 1, 1997.

   The specific proforma adjustments reflected in the attached statements are 
as follows:


A.  CASH AND CASH EQUIVALENTS
    Proceeds from the sale of Series E and Series F Preferred
Stock were used to repay certain liabilities disclosed below and to
pay related costs of approximately $150,000.

B.  NOTE PAYABLE TO BANK
    Proceeds from the sale of Series E and Series F Preferred
Stock were used to retire the outstanding balance  payable to
Silicon Valley Bank under the Factoring Loan Agreement.  At July
31, 1998, this balance was $978,361.  At the time proceeds from the
sale of Preferred Stock were distributed, the estimated,
outstanding balance was $1,054,568.94.

C.  CURRENT MATURITIES OF LONG-TERM OBLIGATIONS
    Proceeds from the sale of Series E and Series F Preferred
Stock of approximately $300,000 were used to retire the outstanding
balance payable to SIRROM Capital under the 1997 Secured Promissory
Note.  Payment of this indebtedness will cause the Company to
amortize the unamortized discount which arose from the value
ascribed to the warrants issued to SIRROM in connection with the
Secured Promissory Note which have been recorded on the Company's
Balance Sheets as a discount to the face value of the Note.

D.  LONG-TERM OBLIGATIONS, LESS CURRENT MATURITIES
    Proceeds from the sale of Series E and Series F Preferred
Stock of approximately $2,500,000 were used to retire the
outstanding balance payable to SIRROM Capital under the 1996
Secured Promissory Note.  Payment of this indebtedness will cause
the Company to amortize the unamortized discount which arose from
the value ascribed to the warrants issued to SIRROM in connection
with the Secured Promissory Note which have been recorded on the
Company's Balance Sheets as a discount to the face value of the
Note.  In addition, there is a reduction in interest expense
associated with the repayment of this debt as of January 1, 1997.

E.  PAR VALUE AND ADDITIONAL PAID IN CAPITAL
    Each of the Series E and Series F Preferred Stock have a Par
Value of $0.01 per share with an aggregate Par Value of $25.00 for
Series E Preferred Stock and $25.00 for Series F Preferred Stock.
Costs associated with the sale and issuance of these shares have
been deducted from Additional Paid in Capital as reflected on the
Company's Balance Sheets.

    The unaudited pro forma Consolidated Balance Sheet and
Statement of Operations is not necessarily indicative of what the
actual financial position would have been at July 31, 1997, nor
does it purport to represent any projection of what the actual
results would have been had the transactions described above been
consummated on January 1, 1997.

                                 --------------------
                                           
    WHEREAS, the Company desires to obtain additional capital for use in
connection with its business through the issue and sale of certain obligations,
and Purchaser is willing to purchase such obligations from the Company, on the
terms and conditions set forth herein.  Capitalized terms shall have the
meanings assigned by Section 11 unless otherwise defined herein.

    NOW, THEREFORE, in mutual consideration of the premises and the respective
representations, warranties, covenants and agreements contained herein, the
parties agree as follows:

    1.   SALE AND PURCHASE OF STOCK.

         1.1  CONVERTIBLE PREFERRED STOCK.  The Company has authorized the

Exhibit A-1 at a purchase price of $1,000.00 per share, for an aggregate
purchase price of Five Million Dollars ($5,000,000.00).  The Certificate of

the Closing Date.  The Convertible Preferred Stock shall (i) have a Stated Value
of $1,000.00 per share, (ii) entitle the holder to quarterly cumulative
dividends of $30.00 per share (with such quarterly cumulative dividend
increasing by $5.00 for each year after August 31, 2002), (iii) entitle the
holder to vote upon all matters submitted to a vote of the holders of the
Company's common stock, par value $.01 per share (the "Common Stock"),
(iv) entitle the holder to convert such Convertible Preferred Stock into shares

respect to liquidating distributions to all other Preferred Stock issued by the
Company (unless otherwise authorized by vote of the holders of the Convertible

rights and preferences as are set forth by the Certificate of Designation.

         1.2  PAYMENT OF DIVIDENDS; AUTOMATIC DEBIT. The Convertible Preferred

business days prior to such payment dates the Company shall have notified 
Purchaser in writing that such dividends have not been declared.

         1.3  REDEMPTION FEATURE.  The Series E Convertible Preferred Stock may
be redeemed, at the option of the Company, at any time, PROVIDED the average

Conversion Price, and the Redemption Price per share shall be the sum of
(i) $1,000.00, (ii) all accrued but unpaid dividends, and (iii) interest on such
accrued but unpaid dividends at an annual rate of 14.0% (or, if less, the
maximum rate allowable by law).  The Series F Convertible Preferred Stock may be
redeemed, at the option of the Company, at any time on or after June 30, 1998;
PROVIDED the average closing bid price of the Company's Common Stock for the 20

exceeds 200% of the Series F Conversion Price, and the Redemption Price per
share shall be the sum of (i) $1,000.00, (ii) all accrued but unpaid dividends,
and (iii) interest on such accrued but unpaid dividends at an annual rate of
14.0% (or, if less, the maximum rate allowable by law).  PROVIDED, that if the

anniversary of the Closing Date, the Company shall pay to the holder of such
Series E Convertible Preferred Stock, in addition to the Redemption Price, a

FURTHER PROVIDED, the Convertible Preferred Stock may be redeemed, at the option
of the Company, at any time on or after August 31, 2002, and the Redemption
Price per share shall be the sum of (i) $1,000.00, (ii) all accrued but unpaid

good standing in every jurisdiction in which such qualification is necessary
under applicable law, except where the failure to so qualify would not have a
Material Adverse Effect on the financial condition or results of operations of
the Company.  All of the outstanding shares of capital stock, or other equity
interest, of each Subsidiary owned, directly or indirectly, by the Company have
been validly issued, are fully paid and nonassessable, and except as set forth

the Company and its Subsidiaries for the fiscal years ended December 31, 1996,

prepared in accordance with generally accepted 



                                     -17-

any Applicable Contract, or other material instrument or agreement to which the

or its respective properties may be bound, except for any such default or event
of default which would not reasonably be expected to cause a Material Adverse

not reasonably be expected to cause a Material Adverse Event.

         2.12 TAXES.  Except as set forth on SCHEDULE 2.12, the Company and its
Subsidiaries have filed or caused to be filed all federal, state and local
income, excise and franchise tax returns required to be filed (except for

                                        -20-

         2.26 GOVERNMENTAL CONSENTS.  No consent, approval, qualification,

contract, patent disclosure agreement, or other contract or agreement 
relating to the relationship of any such employee with the Company, or any 
other party because of the nature of the business conducted or presently 
proposed to be conducted by the Company or to the use by the employee of his 
or her best efforts with respect to such 

                                  -23-

business.  Other than as set forth on SCHEDULE 2.27 hereto, the Company is 
not a party to or bound by any employment contract, deferred compensation 
agreement, bonus plan, incentive plan, profit sharing plan, retirement 
agreement, or other employee compensation agreement.  To the knowledge of the 
Company, no officer or key employee, or any group of key employees, intends 
to terminate employment with the Company, nor does the Company have a present 
intention to terminate the employment of any of the foregoing.  Subject to 
general principles related to wrongful termination of employees and to 
existing employment contracts set forth on SCHEDULE 2.27, the employment of 
each officer and employee of the Company is terminable at the will of the 
Company.

         2.28 ERISA.  The Company is in compliance in all material respects 
with all applicable provisions of Title IV of the Employee Retirement Income 
Security Act of 1974, Pub. L. No. 93-406, September 2, 1974, 88 Stat. 829, 
29 U.S.C.A. SS 1001 et seq. (1975), as amended from time to time ("ERISA"). 
Neither a reportable event nor a prohibited transaction (as defined in ERISA) 
has occurred and is continuing with respect to any "pension plan" (as such 
term is defined in ERISA, a "Plan"); no notice of intent to terminate a Plan 
has been filed nor has any Plan been terminated; no circumstances exist which 
constitute grounds entitling the Pension Benefit Guaranty Corporation 
(together with any entity succeeding to or all of its functions, the "PBGC") 
to institute proceedings to terminate, or appoint a trustee to administer, a 
Plan, nor has the PBGC instituted any such proceedings; neither the Company 
nor any commonly controlled entity (as defined in ERISA) has completely or 
partially withdrawn from a multiemployer plan (as defined in ERISA).  The 
Company and each commonly controlled entity has met its minimum funding 
requirements under ERISA with respect to all of its Plans and the present 
fair market value of all Plan property equals or exceeds the present value of 
all vested benefits under each Plan, as determined on the most recent 
valuation date of the Plan and in accordance with the provisions of ERISA and 
the regulations thereunder for calculating the potential liability of the 
Company or any commonly controlled entity to the PBGC or the Plan under Title

    3.   REPRESENTATIONS AND WARRANTIES OF PURCHASER.  The Purchaser 
hereby represents to the Company as follows:

         3.1  CORPORATE STATUS.  Purchaser is a corporation duly organized, 
validly existing and in good standing under the laws of the State of 
Tennessee and has the corporate power to own and operate its properties, to 
carry on its business as now conducted and to enter into and to perform its 
obligations under this Agreement and any other document executed or delivered 
by Purchaser in connection herewith.

         3.2  AUTHORIZATION.  Purchaser has full legal right, power and 
authority to enter into and perform its obligations under this Agreement and 
any other document executed and delivered by Purchaser in connection 
herewith, without the consent or approval of any other person, firm, 
governmental agency or other legal entity.  The execution and delivery of 
this Agreement and any other document executed and delivered by Purchaser in 
connection herewith, and the performance by Purchaser of its obligations 
hereunder and/or thereunder are within the corporate powers of Purchaser, 
have received all necessary governmental approvals, if any were required, 
have been duly authorized by all necessary corporate action properly taken, 
and do not and will not contravene or conflict with (i) the Charter or Bylaws 
of Purchaser, (ii) any material agreement to which Purchaser is a party or by 
which it or any of its properties is bound, or constitute a default 
thereunder, or result in the creation or imposition of any lien, charge, 
security interest or encumbrance of any nature upon any of the property or 
assets of Purchaser pursuant to the terms of any such agreement or 
instrument, or (iii) violate any provision of law or any applicable judgment, 
ordinance, regulation or order of any court or governmental agency.  The 
officer(s) executing this Agreement and any other document executed and 
delivered by Purchaser in connection herewith, is duly authorized to act on 
behalf of  Purchaser.

         3.3  VALIDITY AND BINDING EFFECT.  This Agreement and any other 
document executed and delivered by Purchaser in connection herewith are the 
legal, valid and binding obligations of the Purchaser, enforceable against it 
in accordance with their respective terms.

         3.4  ACCREDITED INVESTOR, INVESTMENT INTENT.  In connection with the 
issuance and sale to Purchaser of the Convertible Preferred Stock and shares 
of Common Stock issuable upon conversion thereof pursuant to this Agreement, 
Purchaser further represents and warrants to the Company as follows:

         (a)  PURCHASE FOR INVESTMENT.  Purchaser is acquiring the 
Convertible Preferred Stock and any shares of Common Stock issuable upon 
conversion thereof for its own account as principal, for investment, and not 
with a view to the distribution or resale thereof, in whole or in part, in 
violation of the Securities Act or any applicable state securities law, and 
Purchaser has no present intention of selling, negotiating or otherwise 

                                  -25-

<PAGE>

disposing of the Convertible Preferred Stock or shares of Common Stock 
issuable upon conversion thereof.

         (b)  NO REGISTRATION; RULE 144.  (i)  Neither the Convertible 
Preferred Stock nor the shares of Common Stock issuable upon conversion 
thereof have been registered under the Securities Act, and as such, such 
shares of Convertible Preferred Stock and any shares of Common Stock issuable 
upon conversion thereof are "restricted securities" as defined in Rule 144; 
(ii) neither the shares of Convertible Preferred Stock nor the shares of 
Common Stock issuable upon conversion thereof may be resold unless they are 
registered under the Securities Act or unless an exemption therefrom is 
available; (iii) the Purchaser understands that the availability of Rule 144 
for the sale and transfer of the Convertible Preferred Stock and any shares 
of Common Stock issuable upon conversion thereof is limited, and that certain 
conditions and events must exist and occur before Purchaser would be able to 
utilize Rule 144 in connection with the sale or other disposition of the 
Convertible Preferred Stock or shares of Common Stock issuable upon 
conversion thereof.

         (c)  INVESTMENT COMPANY; ACCESS TO INFORMATION.  Purchaser is a 
registered investment company under the Investment Company Act and as such is 
an "accredited investor" under Rule 501(a) under the Securities Act.  
Purchaser understands that its investment in the Convertible Preferred Stock 
involves a high degree of risk.  Purchaser has such knowledge and experience 
in financial and business matters that it is capable of evaluating the merits 
and risks of the investments contemplated by this Agreement.  Purchaser has 
been afforded, to the satisfaction of Purchaser, the opportunity to review 
the financial and other information which it has requested from the Company, 
and to obtain such additional publicly available information concerning the 
Company and its business, and to ask such questions and receive such answers 
(based upon publicly available information), as the Purchaser deems necessary 
to make an informed investment decision.

         (d)  RELIANCE ON REPRESENTATIONS OF PURCHASER.  Purchaser 
understands that the Convertible Preferred Stock is being offered and sold, 
and the shares of Common Stock issuable upon conversion thereof are being 
offered, to Purchaser in reliance on specific exemptions from the 
registration requirements of the United States securities laws and that the 
Company is relying of the truth and accuracy of, and the Purchaser's 
compliance with, the representations, warranties, agreements, acknowledgments 
and understandings set forth herein in order to determine the availability of 
such exemptions and the eligibility of Purchaser to acquire the Convertible 
Preferred Stock and the shares of Common Stock issuable upon conversion 
thereof.

         (e)  TRANSFER TO SUBSIDIARY.  Notwithstanding anything in this 
Section 3.4 to the contrary, Purchaser may transfer and assign its rights and 
obligations under this Agreement to one or more of its Wholly-owned 
Subsidiaries, provided that any such Subsidiary shall agree to become bound 
by the terms of this Agreement, including the representations and warranties 
contained in this Section 3.4, and provided, further that 

                                  -26-

<PAGE>

Purchaser shall remain liable for the performance of its obligations 
hereunder notwithstanding any such assignment.

         3.5  NO CONFLICTS.  The execution, delivery and performance of this 
Agreement by the Purchaser and the consummation by the Purchaser of the 
transactions contemplated hereby or relating hereto do not and will not (i) 
result in the violation of the Purchaser's charter documents or by-laws, or 
(ii) conflict with, or constitute a default (or an event which with notice or 
lapse of time or both would become a default) under, any agreement, indenture 
or instrument to which the Purchaser is a party, or, to the actual knowledge 
of the Purchaser, result in a violation of any law, rule, regulation, order, 
judgment or decree of any court of governmental agency applicable to the 
Purchaser or its properties (except for such conflicts, defaults and 
violations as would not, individually or in the aggregate, have a material 
adverse effect on the Purchaser).  The Purchaser is not required to obtain 
any consent, authorization or order of, or make any filing or registration 
with, any court of governmental agency in order for it to execute, deliver or 
perform any of its obligations under this Agreement or purchase the 
Convertible Preferred Stock in accordance with terms hereof.

         3.6  SURVIVAL.  The representations and warranties of the Purchaser 
contained in this Agreement shall survive until the first anniversary of the 
date hereof.

force and effect, its corporate existence and good standing in the state of 
incorporation thereof, its qualification and good standing as a foreign 
corporation in each jurisdiction where such qualification is required by 
applicable law except where the failure to so qualify would not have a 
Material Adverse Effect on the financial condition or results of operations 
of the Company, and all licenses and permits necessary to the proper conduct 
of its business.

         6.3  MAINTENANCE OF PROPERTIES, ETC.  The Company will maintain, 
preserve and keep, and will cause each Subsidiary to maintain, preserve and 
keep, its properties and assets which are used or useful in the conduct of 
its business (whether 

                                  -29-

<PAGE>

owned in fee or pursuant to a leasehold interest) in good repair and working 
order and from time to time will make all necessary repairs, replacements, 
renewals and additions so that at all times the efficiency thereof shall be 
maintained.

         6.4  NATURE OF BUSINESS.  Neither the Company nor any Subsidiary 
will engage in any business if, as a result, the general nature of the

general nature of the business engaged in by the Company and its Subsidiaries 
on the date of this Agreement.

levies imposed upon the property or business of the Company or such 
Subsidiary, respectively, (ii) all trade accounts payable in accordance with 
usual and customary business terms, and (iii) all claims for work, labor or 
materials, which if unpaid might become a lien or charge upon any property of 
the Company or such Subsidiary; provided the Company or such Subsidiary shall 
not be required to pay any such tax, assessment, charge, levy, account 
payable or claim if (i) the validity, applicability or amount thereof is 
being contested in good faith by appropriate actions or proceedings which 
will prevent the forfeiture or sale of any property of the Company or such 
Subsidiary or any material interference with the use thereof by the Company 
or such Subsidiary, and (ii) the Company or such Subsidiary shall set aside 
on its books, reserves deemed by it to be adequate with respect thereto.

         6.7  COMPLIANCE WITH LAWS, AGREEMENTS, ETC.  Except where failure to

local laws, regulations and ordinances, and such laws, regulations and 
ordinances of foreign jurisdictions, governing such business operations and

termination of the Plan; and (ii) the Company will send to Purchaser a copy 
of any notice of a reportable event (as defined in ERISA) required by ERISA 
to be filed with the Labor Department or the PBGC, at the time that such 
notice is so filed.

keep, and will cause each Subsidiary to keep, proper books of record and 
account in which full and correct entries will be made of all dealings or 
transactions of or in relation to the business and affairs of the Company or 
such Subsidiary, in accordance with GAAP consistently maintained.  The 
Company shall permit a representative of Purchaser to visit any of its 
properties and inspect its corporate books and financial records, and will

trading days ending on June 30, 1998.

         7.2  RESERVATION OF SHARES.  The Company shall take all such

Preferred Stock may be converted.

shall constitute an "Event of Default" under this Agreement:

         (a)  Default shall occur in the payment of any dividends when the 
same shall have accrued and be due and payable; provided, that any such

    10.  AMENDMENTS, WAIVERS AND CONSENTS.

         10.1 CONSENT REQUIRED.  Any term, covenant, agreement or condition

Exhibit 99.3

                          REGISTRATION RIGHTS AGREEMENT
                          -----------------------------

    This Registration Rights Agreement (the "Agreement") dated this 29th day of
August, 1997, is by and between VISTA INFORMATION SOLUTIONS, INC., a Minnesota
corporation (the "Company"), and SIRROM CAPITAL CORPORATION d/b/a TANDEM
CAPITAL, a Tennessee corporation (the "Holder").  Capitalized terms not
otherwise defined shall have the meanings assigned by Section 11.

                               W I T N E S S E T H:
                               --------------------

    WHEREAS, the Company and the Holder have entered into a certain Convertible
Preferred Stock Purchase Agreement (the "Preferred Stock Purchase Agreement") of
even date herewith that provides for, among other things, the Company to grant
to Holder certain registration rights with respect to shares of the Company's
common stock, $.01 par value per share (the "Common Stock"), as set forth
herein; and

    NOW, THEREFORE, in consideration of the mutual covenants and undertakings
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

    1.   Demand Registration.

         1.1  DEMAND RIGHTS.  If the holders of at least 25% of the Registrable
Securities outstanding ("Initiating Holders") request in writing (a "Demand
Request") that the Company register an offering of Registrable Securities under
the Securities Act of 1933, by underwriters selected by the Initiating Holders
and reasonably acceptable to the Company, with anticipated gross offering
proceeds of at least $1,000,000, the Company shall:

              (i)  promptly give Notice of the Demand Request to all other
    holders of Registrable Securities; and

              (ii)  use its best efforts to effect the registration and sale of
    such Registrable Securities, together with all other Registrable Securities
    specified in any written request received by the Company within 20 days
    after the date of the Notice of Demand Request, in accordance with the
    intended method of disposition thereof, and in accordance with the
    procedures set forth in Section 6.

         1.2  NUMBER OF DEMAND REGISTRATIONS.  Initiating Holders shall be
entitled to request three registrations of Registrable Securities pursuant to
this Section 1; and the Company shall pay all Registration Expenses in
connection with each such registration request.  A registration shall not count
towards the maximum of three registration requests held by the Holder hereunder
unless the registration statement for such requested registration has become
effective and an offering closed in which all Registrable Securities requested
to be included in such registration by the Initiating Holders shall have been
sold.  Provided, however, that the Company in any event shall pay all
Registration Expenses in connection with any requested


                                         -45-
<PAGE>

registration whether or not the registration statement becomes effective (unless
the failure to become effective is such as to require the Initiating Holders to
pay all Registration Expenses for such aborted or withdrawn registration
pursuant to Section 4 below, in which case (i) such Initiating Holders shall
reimburse the Company for all such Registration Expenses incurred and paid by
the Company in connection with such registration, and (ii) such withdrawn
request shall not count as a requested registration hereunder).  Further
provided, that if (i) the Initiating Holders withdraw from or abort more than
one registration in any consecutive 12-month period, and (ii) the Initiating
Holders are required to pay Registration Expenses pursuant to Section 4 for more
than one such withdrawn or aborted registration, only one such registration
shall not be counted.

         1.3  OTHER SECURITIES AND PRIORITY.  The registration statement filed
pursuant to the Demand Request may, subject to the prior written consent of the
Initiating Holders, include other securities of the Company, provided that all
Registrable Securities for which the Initiating Holders have requested
registration shall be covered by such registration statement and sold in such
offering before any such other securities are included and sold.

         1.4  LIMITATIONS.  The Company shall not be obligated to effect, or to
take any action to effect, any demand registration:

              (i)  in any jurisdiction in which the Company would be required
    to execute a general consent to service of process, unless the Company is
    already subject to service in such jurisdiction and except as may be
    required by the Securities Act;

              (ii)  during the period beginning 15 days prior to the Company's
    good faith estimate of the date of filing of, and ending 180 days after the
    effective date of, a Company-initiated registration, provided that the
    Company is actively employing in good faith all reasonable efforts to cause
    such registration statement to become effective; or

              (iii)  if the Initiating Holders propose to dispose of shares of
    Registrable Securities which may be immediately registered on Form S-3
    pursuant to a request made under Section 3 hereof.

         1.5  DEFERRAL OF REGISTRATION.  If (i) in the good faith judgment of
the Board of Directors of the Company, the filing of a registration statement as
soon as practicable after receipt of the Demand Request would be materially
detrimental to the Company because there exist BONA FIDE financing, acquisition,
or other activities of the Company, and the Board of Directors of the Company
concludes, as a result, that it is essential to defer the filing of such
registration statement at such time, and (ii) the Company shall furnish to the
Initiating Holders a certificate signed by the President of the Company stating
that in the good faith judgment of the Board of Directors of the Company, it
would be materially detrimental to the Company for such registration statement
to be filed in the near future and that it is essential to defer the filing of
such registration statement, then the Company may defer such filing for a period
of not more than 90 days after receipt of the Demand Request of the Initiating
Holders, provided that the Company shall not defer its obligations in this
manner for more than an aggregate of 90 days in


                                         -46-
<PAGE>

any twelve-month period, and provided further that the Initiating Holders shall
be entitled to withdraw the request for registration within 30 days after
receipt of such certificate and, if such request is withdrawn, such registration
shall not count as a requested registration hereunder and the Company shall pay
all Registration Expenses incurred in connection with such withdrawn
registration request.

         1.6  UNDERWRITING.  The right of any other holders of Registrable
Securities to join in a request for registration shall be conditioned upon such
holders' participation in such registration on the same terms as the Initiating
Holders (unless otherwise agreed by a majority in interest of the Initiating
Holders).

         1.7  INCLUSION OF OTHER SECURITIES. In any demand registration, if the
Company shall request inclusion of securities to be sold for its own account, or
if other persons entitled to incidental registrations shall request inclusion in
such registration, the Initiating Holders shall offer to include such securities
in the underwriting and may condition such offer on the acceptance by the
Company or such other persons of the provisions of this Agreement and the
underwriting.  The Company and all such other persons proposing to distribute
securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriters selected by a majority in interest of
the Initiating Holders and reasonably acceptable to the Company.

         1.8  TIME.  No Demand Request may be made prior to the earlier of
(i) July 1, 1998, or (ii) the closing of a Qualified Offering as defined by the
Preferred Stock Purchase Agreement.

    2.   PIGGYBACK REGISTRATION.

         2.1  NOTICE AND PROCEDURES.  If the Company proposes to register any
of its Common Stock either for its own account or for the account of other
security holders (other than holders of Registrable Securities), the Company
will:

              (i)  promptly give written notice thereof to each holder of
    Registrable Securities; and

              (ii) use its best efforts to include in such registration and in
    any underwriting involved therein, all Registrable Securities specified in
    any written request from holders of Registrable Securities received by the
    Company within 15 days after such notice.

         2.2  LIMITATIONS.  The provisions of this Section 2 shall not apply to
any registration relating solely to employee benefit plans (as defined under
Rule 405 of the Securities Act), or a registration relating solely to securities
issued in connection with an acquisition or merger, or a registration on any
registration form that does not permit secondary sales.

         2.3  UNDERWRITING.  The right of any holder of Registrable Securities
to participate in a piggyback registration shall be conditioned upon such
holder's agreement to enter


                                         -47-
<PAGE>

into an underwriting agreement in customary form with the underwriters selected
by the Company.

         2.4  UNDERWRITERS' CUTBACK.  Notwithstanding any other provision of
this Section 2, if the underwriters of any piggyback registration advise the
Company of the need for an Underwriters' Cutback, the underwriters may (subject
to the limitations set forth below) limit the number of Registrable Securities
to be included in the registration and sold.  The Company shall advise all
holders of securities requesting registration of the Underwriters' Cutback, and
the number of shares of securities that are entitled to be included in the
registration and underwriting shall be allocated first to the Company for
securities being sold for its own account and thereafter as set forth in
Section 9.

         2.5  OTHER PROVISIONS.  If holders of Registrable Securities request
participation in a piggyback registration, the provisions of Section 1.4 shall
apply to such registration, and if the registration is for an underwritten
offering, the provisions of Sections 1.6 and 1.7 shall also apply to such
registration.

    3.   REGISTRATION ON FORM S-3.  After the Company has qualified for the use
of Form S-3, and for so long as the Company continues to be so qualified, in
addition to the rights contained in the foregoing provisions of this Agreement,
the holders of the Registrable Securities shall have the right to request
registrations on Form S-3 or any comparable or successor form.  Each such
request shall be in writing and shall state the anticipated number of shares of
Registrable Securities to be disposed of, the anticipated gross proceeds of the
offering, and the intended methods of disposition of such shares by such
holders, including whether sales are to be made on a delayed or continuous basis
pursuant to Rule 415.  The Company shall not be obligated to effect any
registration pursuant to this Section 3 if (i) the holders of Registrable
Securities, together with the holders of any other securities of the Company
entitled to inclusion in such registration, propose to sell Registrable
Securities and such other shares of Common Stock (if any) on Form S-3 at an
aggregate price to the public of less than $500,000, or (ii) the Company shall
delay or defer registration in accordance with Section 1.4(ii) or Section 1.5,
or (iii) the Company will be required to obtain an audit (other than for its
normal year-end audit) for such registration to become effective.  The Company
shall only be required to effect two registrations of Registrable Securities
pursuant to this Section 3 in each calendar year, provided, however, that if the
offering is to be effected on a continuous or delayed basis pursuant to Rule 415
(or any successor rule), and the registration statement is kept effective for a
period in excess of 180 days, then the Company shall not be required to effect
another registration in that calendar year.

    4.   EXPENSES OF REGISTRATION.  All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to this
Agreement, shall be borne by the Company; provided, however, that the holders of
Registrable Securities who participate in a registration shall bear the
Registration Expenses for any registration process begun pursuant to Section 1
pr Section 3 and subsequently withdrawn by such holder, unless such withdrawal
is based upon (i) material adverse information relating to the Company that is
different from the information known or available (upon request from the Company
or otherwise) to the Initiating


                                         -48-
<PAGE>

Holders at the time of the request for registration under Section 1, or
(ii) material adverse changes in the financial markets which result in a
significant decline in the public market price for the Company's Common Stock of
at least 20 percent from the date of the request to the date of such withdrawal.
All Selling Expenses relating to securities registered pursuant to this
Agreement shall be borne by the holders of such securities PRO RATA on the basis
of the number of shares of securities so registered on their behalf.

    5.   HOLDBACK AGREEMENTS.

         5.1  BY HOLDERS.  If requested in writing by the Company and the
managing underwriter of an underwritten registered public offering by the
Company of its Common Stock, the holders of Registrable Securities shall agree
not to sell or otherwise transfer or dispose of any Common Stock of the Company
held by such holders (other than those included in the registration statement)
for a period not to exceed 180 days following the effective date of a
registration statement of the Company filed under the Securities Act, provided
that all officers and directors of the Company, and all other holders of rights
to registration of any other security of the Company, enter into similar
agreements identical in terms to that of the holders of Registrable Securities.

         5.2  BY COMPANY.  In connection with any underwritten registration,
the Company shall not effect any public sale or distribution of its equity
securities, or any securities convertible into or exchangeable or exercisable
for such securities, during the seven days prior to and during the 90-day period
after the effective date of any underwritten registration pursuant to this
Agreement.

    6.   REGISTRATION PROCEDURES.  In the case of each registration effected by
the Company pursuant to this Agreement, the Company will use its best efforts to
effect the registration and sale of Registrable Securities in accordance with
the intended method of disposition thereof, and pursuant thereto the Company
shall as expeditiously as possible:

              (i)  prepare and file a registration statement with respect to
    such offering of Registrable Securities, and use its best efforts to cause
    such registration statement to become effective;

              (ii)  notify each holder of Registrable Securities of the
    effectiveness of each registration statement hereunder and prepare and file
    with the Securities and Exchange Commission such amendments and supplements
    to such registration statement and the prospectus used in connection
    therewith as may be necessary to keep such registration statement effective
    for a period of not less than 180 days or (if less) until all securities
    that have been registered are sold, and comply with the provisions of the
    Securities Act with respect to the disposition of all securities covered by
    such registration statement during such period in accordance with the
    intended methods of disposition the sellers thereof set forth in such
    registration statement;


                                         -49-
<PAGE>

              (iii)  furnish to each seller of Registrable Securities such
    number of copies of such registration statement, each amendment and
    supplement thereto, the prospectus included in such registration statement
    (including each preliminary prospectus) and such other documents as such
    seller may reasonably request in order to facilitate the disposition of the
    Registrable Securities owned by such seller;

              (iv)  use its best efforts to register or qualify such Registrable
    Securities under such other securities or blue sky laws of such
    jurisdictions as any seller reasonably requests and do any and all other
    acts and things which may be reasonably necessary or advisable to enable
    such seller to consummate the disposition in such jurisdictions of the
    Registrable Securities owned by such seller;

              (v)  notify each seller of such Registrable Securities, at any
    time when a prospectus relating thereto is required to be delivered under
    the Securities Act, of the happening of any event as a result of which the
    prospectus included in such registration statement contains an untrue
    statement of a material fact or omits any fact necessary to make the
    statements therein not misleading, and, at the request of any such seller,
    the Company shall prepare a supplement or amendment to such prospectus so
    that, as thereafter delivered to the purchasers of such Registrable
    Securities, such prospectus shall not contain an untrue statement of a
    material fact or omit to state any fact necessary to make the statements
    therein not misleading;

              (vi)  cause all such Registrable Securities to be listed on each
    securities exchange on which similar securities issued by the Company are
    then listed and, if not so listed, to be listed on the NASD automated
    quotation system and, if listed on the NASD automated quotation system, and
    if in compliance with applicable listing standards, use its best efforts to
    secure designation of all such Registrable Securities covered by such
    registration statement as a NASDAQ "national market system security" within
    the meaning of Rule 11a2-1 of the Securities and Exchange Commission or,
    failing that, to secure NASDAQ authorization for such Registrable
    Securities and, without limiting the generality of the foregoing, to
    arrange for a least two market makers to register as such with respect to
    such Registrable Securities with the NASD;

              (vii)  provide a transfer agent and registrar for all such
    Registrable Securities not later than the effective date of such
    registration statement;

              (viii)  enter into such customary agreements (including 
    underwriting agreements in customary form) and take all such other actions 
    as the holders of a majority of the Registrable Securities being sold or the
    underwriters, if any, reasonably request in order to expedite or facilitate
    the disposition of such Registrable Securities (including effecting a stock
    split or combination of shares);

              (ix)  make available for inspection by any seller of Registrable
    Securities, any underwriter participating in any disposition pursuant to
    such registration statement, and any attorney, accountant or other agent
    retained by any such seller or


                                         -50-
<PAGE>

    underwriter, all financial and other records, pertinent corporate documents
    and properties of the Company, and cause the Company's officers, directors,
    employees and independent accountants to supply all information reasonably
    requested by any such seller, underwriter, attorney, accountant or agent in
    connection with such registration statement, provided that any recipient of
    such records, documents or information executes such confidentiality
    agreement as the Company reasonably requests;

              (x)  otherwise use its best efforts to comply with all applicable
    rules and regulations of the Securities and Exchange Commission, and make
    available to its security holders, as soon as reasonably practicable, an
    earnings statement covering the period of at least twelve months beginning
    with the first day of the Company's first full calendar quarter after the
    effective date of the registration statement, which earnings statement
    shall satisfy the provisions of Section 11(a) of the Securities Act and
    Rule 158 thereunder;

              (xi)  permit any holder of Registrable Securities which holder, in
    its sole and exclusive judgment, might be deemed to be an underwriter or
    controlling person of the Company, to participate in the preparation of
    such registration or comparable statement and to require the insertion
    therein of material, furnished to the Company in writing, which (i) with
    respect to matters relating to such holder of Registrable Securities,
    should be included in the reasonable judgment of such holder and its
    counsel, and (ii) with respect to matters relating to the Company, should
    be included in the reasonable judgment of such holder, subject in the case
    of clause (ii) to the approval of the Company and any managing underwriter
    of the offering (which approval shall not be unreasonably withheld);

              (xii)  use its best efforts to cause such Registrable
    Securities covered by such registration statement to be registered with or
    approved by such other governmental agencies or authorities in the United
    States as may be necessary to enable the sellers thereof to consummate the
    disposition of such Registrable Securities; and

              (xiii)  in connection with any underwritten registration,
    obtain a cold comfort letter from the Company's independent public
    accountants in customary form and covering such matters of the type
    customarily covered by cold comfort letters as the holders of a majority of
    the Registrable Securities being sold reasonably request (provided that
    such Registrable Securities constitute at least 10% of the securities
    covered by such registration statement).

    7.   INDEMNIFICATION.

         7.1  BY COMPANY.  The Company shall indemnify each holder of
Registrable Securities, each of its officers, directors, employees, agents, and
Affiliates, and each underwriter, and each of its officers, directors,
employees, agents, and Affiliates, against all expenses, claims, losses,
damages, and liabilities (or actions, proceedings, or settlements in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained


                                         -51-
<PAGE>

in any prospectus (including any related registration statement, notification,
or the like) incident to any registration under this Agreement, or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
any violation by the Company of the Securities Act or any rule or regulation
thereunder applicable to the Company and relating to action or inaction required
of the Company in connection with any such registration, and will reimburse such
persons for any legal and any other expenses reasonably incurred in connection
with investigating and defending or settling any such claim, loss, damage,
liability or action, provided that the Company will not be liable in any such
case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by such holder or underwriter and stated to
be specifically for use therein.  It is agreed that the indemnity agreement
contained in this Section shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the prior written consent of the Company, which consent shall not be
unreasonably withheld.

         7.2  BY HOLDERS.  In connection with the registration or sale of
shares of Registrable Securities pursuant to this Agreement, each holder whose
Registrable Securities are included in such registration being effected under
this Agreement, shall indemnify the Company, and each of its directors,
officers, employees, agents, and Affiliates, and each underwriter, and each of
its directors, officers, employees, agents, and Affiliates, against all claims
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement or prospectus, or any omission
(or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse such persons for any legal or any other expenses reasonably incurred
in connection with investigating or defending any such clam, loss, damage,
liability, or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement or prospectus, in reliance upon
and in conformity with written information furnished to the Company by such
holder of the Registrable Securities, and stated to be specifically for use
therein; provided, however, that the obligations of such holder hereunder shall
not apply to amounts paid in settlement of any such claims, losses, damages, or
liabilities if such settlement is effected without the prior written consent of
such holder, which consent shall not be unreasonably withheld; and provided that
in no event shall any indemnity under this Section 7.2 exceed the net amount of
proceeds from the offering received by such holder.

         7.3  PROCEDURE.  Each party entitled to indemnification under this
Section (the "Indemnified Party") shall give notice to the party or parties
required to provide indemnification (the "Indemnifying Party") promptly after
such Indemnified Party has actual knowledge of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be reasonably acceptable to the
Indemnified Party.  Failure to give notice as provided herein shall not relieve
the Indemnifying Party of its obligations under this section to


                                         -52-
<PAGE>

the extent such failure is not prejudicial to the interests of the Indemnifying
Party.  No Indemnifying Party, in the defense of any such claim or litigation,
shall, except with the consent of each Indemnified Party, consent to entry of
any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.  Each Indemnified Party shall furnish such information regarding
itself or the claim in question as an Indemnifying Party may reasonably request
in writing and as shall be reasonably required in connection with defense of
such claim and litigation resulting therefrom.

         7.4  CONTRIBUTION.  If the indemnification provided for in this
Section is held by a court of competent jurisdiction to be unavailable to an
Indemnified Party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the Indemnifying Party, in lieu of indemnifying such
Indemnified Party hereunder, shall contribute to the amount paid or payable by
such Indemnified Party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand and of the Indemnified Party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations.  The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party, and the parties' relative
intent, knowledge, access to information, and opportunity to correct or prevent
such statement or omission.

         7.5  CONFLICTING PROVISIONS.  Notwithstanding the foregoing, to the
extent that the provisions on indemnification and contribution contained in any
underwriting agreement entered into in connection with a registration are in
conflict with the foregoing provisions, the provisions of the underwriting
agreement shall control.

    8.   INFORMATION BY HOLDER.  Each holder of Registrable Securities shall
furnish to the Company in writing such information regarding such holder and the
distribution proposed by such holder as the Company or underwriters may
reasonably request in writing and as shall be reasonably required in connection
with any registration, qualification, or compliance referred to in this
Agreement.

    9.   ALLOCATION OF REGISTRATION OPPORTUNITIES.  In any circumstance in
which all of the Registrable Securities and other outstanding shares of Common
Stock of the Company (the "Other Shares") requested and entitled to be included
in a demand registration cannot be so included as a result of limitations on the
aggregate number of shares of Registrable Securities and Other Shares that may
be so included, or in case of an Underwriters' Cutback, the number of shares of
Registrable Securities and Other Shares that may be so included shall be
allocated among the holders of Registrable Securities and other selling
stockholders PRO RATA on the basis of the number of shares of Registrable
Securities and Other Shares held by such holders and other selling stockholders.
If any holder of Registrable Securities or other selling stockholder does not
request inclusion of the maximum number of shares of Registrable Securities and
Other


                                         -53-
<PAGE>

Shares allocated to him pursuant to this procedure, the remaining portion of his
allocation shall be reallocated among those requesting holders of Registrable
Securities and other selling stockholders whose allocations did not satisfy
their requests PRO RATA on the basis of the number of shares of Registrable
Securities and Other Shares held by such holders and other selling stockholders,
and this procedure shall be repeated until all of the shares of Registrable
Securities and Other Shares which may be included in the registration on behalf
of the holders of Registrable Securities and other selling stockholders have
been so allocated. Provided, however, the Company shall not limit the number of
Registrable Securities to be included in a registration pursuant to this
Agreement in order to include shares held by stockholders with no registration
rights or to include in that registration shares of stock issued to employees,
officers, directors, or consultants pursuant to any Company stock option plan,
and in such case all Registrable Securities covered by the registration shall be
sold before any such other securities are sold.

    10.  SURVIVAL OF RIGHTS.  The right of any holder of Registrable Securities
to request registration or inclusion in any registration pursuant to this
Agreement shall terminate on the earlier of (i) such date as all shares of
Registrable Securities held by Holder shall equal less than 25% of the
outstanding Registrable Securities, or (ii) five years from the date a Demand
Request may first be made under Section 1.8.

applicable state securities laws.

included in any underwritten offering as the result of receipt of written notice
from the representative(s) of the underwriters to the effect that the number of
shares requested to be included in such registration exceeds the number which,
in the representative's judgment, can be sold in an orderly manner in such
offering within a price range acceptable to either the Company (in a primary
registration) or the majority of the holders initially requesting such
registration (in a secondary registration).

         12.  NOTICE OF TRANSFER.  The registration rights granted to the
Holder hereunder may be transferred to any transferee of 250,000 shares

Holder may be transferred to a wholly-owned subsidiary of the Holder without
regard to the number of shares transferred.  Each such permitted transferee must
agree in a written instrument provided to the Company to be bound hereby and
shall thereupon be deemed to be a "Holder" for purposes hereunder.

Exhibit 99.4

SAN DIEGO, Aug. 11 /PRNewswire/ --

VISTA Information Solutions, Inc., (Nasdaq: VINFC) (VISTA) announced today that
it has been granted an exception to the Nasdaq listing requirements for Capital
and Surplus as the result of a recent review by a Nasdaq Listing Qualifications
Panel in Washington.  As a result, the company's stock will continue to be
listed on the Nasdaq Small Cap Market.

While VISTA failed to meet this requirement as of December 31, 1996, the company
has been granted a temporary exception from this standard subject to VISTA
meeting certain conditions.  The exception will expire on September 2, 1997.
During the exception period, the company's stock symbol will change from VINF to
VINFC.

If the company is deemed to have met the terms of the exception by September
2nd, it will continue to be listed on The Nasdaq Small Cap Market. Although
there can be no assurances that it will do so, the company believes that it can
meet the listing requirements through a combination of the conversion of debt to
equity and a private placement.  Both of these actions are already in process
and are being accomplished in anticipation of a secondary offering planned for
early 1998.

"I am pleased to receive the acknowledgment from the Nasdaq panel of the
progress VISTA has made in 1997 to get into compliance with all listing
requirements and our efforts to ensure continued compliance, in the future,"
said Steve Hamilton, VISTA chief financial officer.  "We have made outstanding
progress with sales and profit growth of VISTA as a result of major contract
executions with our Geographic Underwriting Service, (GUS).  Further, with the
completion in the first quarter of 1998 of amortization of $12 million in
goodwill from the 1995 merger of VISTA Environmental Information and DataMap, we
expect to see continued improvement in our results."

VISTA, based in San Diego, Calif., provides computerized geographic information
solutions in the areas of compliance and risk management for the insurance,
finance, and environmental engineering industries.  Its subsidiary, VISTA
Environmental Information, Inc., is the leading national supplier of
environmental information on contaminated and potentially contaminated
commercial, industrial, and residential real estate in the United States.
