Item 5: Other Events

         Indemnification Agreement

         On October 22, 1998, the Company entered into an Indemnification
Agreement effective as of February 21, 1998 with each of its directors
containing provisions that may require the Company, among other things, to
indemnify its directors against certain liabilities that may arise by reason of
their status or service as directors (other than liabilities arising from
willful misconduct of a culpable nature) and to advance their expenses incurred
as a result of any proceeding against them as to which they could be
indemnified.

         The description of the Indemnification Agreement is not complete and is
qualified by reference to the Indemnification Agreement, the form of which is
filed as Exhibit 10.1 hereto.

         Exchange Agreement

         On October 20, 1998, the Company executed an exchange agreement (the
"Agreement") with its largest equity and debt holder, Medical Industries of
America, Inc. ("MIOA"), settling pending litigation with MIOA and resolving all
outstanding issues relating to the Company's stock and debt held by MIOA. The
Agreement supersedes all prior agreements entered into between Westmark and
M.I.O.A.

         The Agreement, among other things, provides for: (1) the conversion of
200,000 shares of Westmark Series C Convertible Preferred Stock ($3.50 stated
value per share) held by MIOA into 350,000 shares of Company common stock, at a
conversion ratio of $2.00 per share (as a result, MIOA now owns 683,458 shares
of Westmark's common stock, or approximately 20.7% of the Company's 3.295
million shares of Common Stock outstanding); (2) the issuance to MIOA of
two-year warrants to buy 100,000 shares of Company common stock at $3.25 per
share; (3) elimination of MIOA's claim to a guaranteed 49% ownership interest in
the Company; (4) satisfaction of a Company Promissory Note payable to MIOA with
a principal balance as of September 30, 1998 of approximately $1,707,555 in
exchange for the return by the Company to MIOA of 172,750 shares of MIOA Series
B Convertible Preferred Stock ($10.00 stated value per share), and payment of
$112,500 by the Company to MIOA; (5) waiver by the Company of the right to
payment of approximately $350,000 of MIOA Series B Convertble Preferred Stock
accrued dividends; and (6) waiver by MIOA of the right to payment of
approximately $179,000 of Westmark Series C Preferred Stock accrued dividends.

         The Agreement also provides the Company with a right to repurchase its
Common Stock held by MIOA at varying prices, and the potential obligation to
repurchase up to $1,000,000 of such stock at various minimum prices if certain
conditions are not met. The Company's obligation to repurchase its stock is
secured by a contingency reserve fund and the 27,250 shares of MIOA Series B
Convertible Preferred Stock retained by the Company.

         The description of the Agreement is not complete and is qualified by
reference to the Agreement and the exhibits to it, copies of which are filed as
Composite Exhibit 99.1 hereto.

                            INDEMNIFICATION AGREEMENT
                            -------------------------

         This Indemnification Agreement ("Agreement") is dated as of February
21, 1998, between Westmark Group Holdings, Inc., a Delaware corporation
("Corporation"), and _____________________ ("Director").

                                    Recitals
                                    --------

         A. Director is a member of Corporation's Board of Directors and
Corporation desires Director to continue in such capacity. Director is willing
to continue to serve on Corporation's Board of Directors if Director receives
the protections provided by this Agreement.

         B. Corporation's Certificate of Incorporation, obligates it to
indemnify its officers and directors as authorized by Section 145 of the General
Corporation Law of the State of Delaware.

         C. Corporation intends to secure, at its expense, directors' and
officers' liability insurance ("D&O Insurance") protecting its directors in
connection with their performance of services for Corporation.

         D. Corporation believes that (1) litigation against corporate
directors, regardless of whether meritorious, is expensive and time-consuming
for the director to defend; (2) there is a substantial risk of a large judgment
or settlement in litigation in which a corporate director was neither culpable
nor profited personally to the detriment of the corporation; (3) it is
increasingly difficult to attract and keep qualified directors because of such
potential liabilities; and (4) it is important for a director to have assurance
that indemnification will be available if the director acts in accordance with
reasonable business standards to the fullest extent permitted by applicable law,
it is in the best interests of Corporation and its shareholders for Corporation
to contractually obligate itself to indemnify its directors and to set forth the
details of the indemnification process.

         E. Based upon the conclusions stated in Recital D above, to induce
Director to continue to serve on Corporation's Board of Directors and in
consideration of Director's continued service as a director, Corporation wishes
to enter into this Agreement with Director.

         Therefore, Corporation and Director agree as follows:


<PAGE>

         1. Agreement to Serve. Director will serve as a member of the Board of
Directors of Corporation so long as Director is duly elected and qualified to so
serve or until Director resigns or is removed from Corporation's Board of
Directors.

         2. Indemnification.

                  (a) Corporation will indemnify Director to the fullest extent
permitted under the governing law in effect on the date hereof or as such laws
may from time to time hereafter be amended to increase the scope of such
permitted indemnification if Director was or is a party or threatened to be made
a party to any threatened, pending or completed action, arbitration, alternative
dispute resolution mechanism, investigation, administrative hearing, or any
other suit or proceeding of any kind, whether civil, criminal, administrative or
investigative and whether formal or informal (including actions by or in the
right of Corporation and any preliminary inquiry or claim by any person or
authority) (collectively, a "Proceeding"), by reason of the fact that Director
is or was a director, officer, employee or agent of Corporation or is or was
serving at Corporation's request as a director, officer, employee or agent of
another corporation (including a Subsidiary), partnership, joint venture, trust
or other enterprise against liability incurred in connection with such
proceeding, including any appeal thereof (collectively, "Covered Matters"). Such
indemnification will cover all Expenses (as defined in paragraph 5(a) below),
liabilities, judgments (including punitive and exemplary damages), penalties,
fines (including excise taxes relating to employee benefit plans and civil
penalties) and amounts paid in settlement which are incurred or imposed upon
Director in connection with a Covered Matter (collectively, "Indemnified
Amounts").

                  (b) Notwithstanding the foregoing provisions of paragraph 2(a)
above, no such indemnification shall be made in respect of any claim, issue, or
matter as to which the governing law expressly prohibits such indemnification by
reason of an adjudication of liability of Director to the Corporation; provided,
however, that in such event such indemnification shall nevertheless be made by
the Corporation to the extent that the court in which such action or suit was
brought shall determine equitable under the circumstances.

                  (c) Notwithstanding any provision of this Agreement, to the
extent that Director has been wholly successful on the merits or otherwise
absolved in any proceeding on any claim, issue or matter, Director shall be
indemnified against all Expenses incurred by Director or on Director's behalf in
connection therewith. If Director is not wholly successful in such Proceeding
but is successful, on the merits or otherwise, as to one or more but less than
all claims, issues or matters in such Proceeding, the Corporation shall
indemnify Director to the maximum extent permitted by law, against all Expenses,
judgments, penalties, fines and amounts paid in settlement, incurred by Director
in connection with each successfully resolved claim, issue, or matter. For
purposes of this paragraph 2, and without limitation, the termination of any
such claim, issue or matter by dismissal with or without prejudice shall be
deemed to be a successful resolution as to such claim, issue or matter.


                                   -2-
<PAGE>

         3. Claims for Indemnification. Director will give Corporation written
notice of any claim for indemnification under this Agreement. Payment requests
will include a schedule setting forth in reasonable detail the amount requested
and will be accompanied (or, if necessary, followed) by copies of the relevant
invoices or other documentation. Upon Corporation's request, Director will
provide Corporation with a copy of the document or pleading, if any, notifying
Director of the Covered Matter. To the extent practicable, Corporation will pay
Indemnified Amounts directly without requiring Director to make any prior
payment.

         4. Determination of Right to Indemnification.

                  (a) Director will be presumed to be entitled to
indemnification under this Agreement and will receive such indemnification,
subject to paragraph 4(b) below, irrespective of whether the Covered Matter
involves allegations of intentional misconduct, alleged violations of Section
16(b) of the Securities Exchange Act of 1934, alleged violations of Section
10(b) of the Securities Exchange Act of 1934 (including Rule 10b-5 thereunder),
breach of Director's fiduciary duties (including duties of loyalty or care) or
any other claim.

                  (b) If, in the opinion of counsel to Corporation, applicable
law permits indemnification in a Covered Matter only as authorized in the
specific case upon a determination that indemnification is proper in the
circumstances because Director has met a standard of conduct established by
applicable law, and upon an evaluation of Indemnified Amounts to be paid in
connection with such Covered Matter, the following will apply:

                           (1) Corporation will give Director notice that a
         determination and evaluation will be made under this paragraph 4(b);
         such notice will be given immediately after receipt of counsel's
         opinion that such a determination and evaluation is necessary and will
         include a copy of such opinion.

                                      -3-
<PAGE>

                           (2) Such determination and evaluation will be made in
         good faith, as follows:

                                    (A) by a majority vote of a quorum of
                  Corporation's Board of Directors who are not parties or
                  threatened to be made parties to the Covered Matter in
                  question ("Disinterested Directors") or, if such a quorum is
                  not obtainable or, even if obtainable, by a majority vote of a
                  committee of two or more Disinterested Directors who are
                  selected by the entire Board; or

                                    (B) by an attorney or firm of attorneys,
                  having no previous relationship with Corporation or Director,
                  which is selected by the Board of Directors or Committee as
                  prescribed in clause (A) above; or

                                    (C) by the shareholders by a majority vote
                  of a quorum consisting of shareholders who were not parties to
                  such proceeding, or, if no such quorum is obtainable, by a
                  majority vote of shareholders who were not parties to such
                  proceeding.

                           (3) Director will be entitled to a hearing before the
         entire Board of Directors of Corporation and any other person or
         persons making the determination and evaluation under clause (2) above.
         Director will be entitled to be represented by counsel at such hearing.

                           (4) The cost of a determination and evaluation under
         this paragraph 4(b) (including attorneys' fees and other expenses
         incurred by Director in preparing for and attending the hearing
         contemplated by clause (3) above and otherwise in connection with the
         determination and evaluation under this paragraph 4(b)) will be borne
         by Corporation.

                           (5) The determination will be made as promptly as
         reasonably possible after notice from counsel to Corporation of the
         need therefor and, in any case, promptly as possible after final
         adjudication of the Covered Matter.

                           (6) Evaluation of the reasonableness of expenses and
         authorization of indemnification shall be made in the same manner as
         the determination that indemnification is permissible. If the
         determination of permissibility is made under clause 2(B) above, the
         same persons shall evaluate the reasonableness of expenses and may
         authorize indemnification.

                                      -4-
<PAGE>

                           (7) Director will be presumed to have met the
         required standard of conduct under this paragraph 4(b) unless it is
         clearly demonstrated to the determining body that Director has not met
         the required standard of conduct.

                  (c) Notwithstanding the failure of Corporation to provide
indemnification, and despite any contrary determination of the Board of
Directors or of the shareholders in the specific case, Director may apply for
indemnification or advancement of expenses, or both, to the court conducting the
proceeding, to the circuit court, or to another court of competent jurisdiction.

         5. Indemnification for Expenses of a Witness.

                  Notwithstanding any other provision of this Agreement, to the
extent that Director is, by reason of the fact that Director is or was a
director, officer, employee or agent of Corporation or any other entity which
Director is or was serving at the request of Corporation, a witness in any
Proceeding, Director shall be indemnified by the Corporation against all
Expenses actually incurred by Director or on Director's behalf in connection
therewith.

         6. Advance of Expenses.

                  (a) Before final adjudication of a Covered Matter, upon
Director's request pursuant to paragraph 3 above, Corporation will promptly
either advance Expenses directly or reimburse Director for all Expenses. As used
in this Agreement, "Expenses" means all costs and expenses (including attorneys'
fees, expert fees, other professional fees and court costs) incurred by Director
in connection with a Covered Matter other than judgments, penalties, fines and
settlement amounts.

                  (b) Expenses incurred by Director in defending a civil or
criminal proceeding may be paid by Corporation in advance of the final
disposition of such proceeding, only upon receipt of an undertaking by or on
behalf of Director to repay such amount if Director is ultimately found by the
court not to be entitled to indemnification by Corporation.

                                      -5-
<PAGE>

         7. Defense of Claim.

                  (a) Except as provided in paragraph 7(c) below, Corporation,
jointly with any other indemnifying party, will be entitled to assume the
defense of any Covered Matter as to which Director requests indemnification.

                  (b) Counsel selected by Corporation to defend any Covered
Matter will be subject to Director's advance written approval, which will not be
unreasonably withheld.

                  (c) Director may employ Director's own counsel in a Covered
Matter and be fully reimbursed therefor if (1) Corporation approves, in writing,
the employment of such counsel or (2) either (A) Director has reasonably
concluded that there may be a conflict of interest between Corporation and
Director or between Director and other parties represented by counsel employed
by Corporation to represent Director in such action or (B) Corporation has not
employed counsel reasonably satisfactory to Director to assume the defense of
such Covered Matter promptly after Director's request.

                  (d) Neither Corporation nor Director will settle any Covered
Matter without the other's written consent, which will not be unreasonably
withheld.

                  (e) If Director is required to testify (in court proceedings,
depositions, informal interviews or otherwise), consult with counsel, furnish
documents or take any other reasonable action in connection with a Covered
Matter, Corporation will pay Director a fee for Director's efforts at a rate
equal to the amount payable to Director for attending Board and Board committee
meetings, plus reimbursement for all reasonable expenses incurred by Director in
connection therewith.

         8. Disputes; Enforcement.

                  (a) If there is a dispute relating to the validity or
enforceability of this Agreement or a denial of indemnification, Advance of
Expenses or payment of any other amounts due under this Agreement or
Corporation's Certificate of Incorporation or Bylaws, Corporation will provide
such indemnification, Advance of Expenses or other payment until a final,
non-appealable judgment that Director is not entitled to such indemnification,
Advance of Expenses or other payment has been rendered by the court of last
resort (or by a lower court if not timely appealed). Director will repay such
amounts if such final, non-appealable judgment so requires.

                                      -6-
<PAGE>

                  (b) Corporation will reimburse all of Director's reasonable
expenses (including attorneys' fees) in pursuing an action to enforce Director's
rights under this Agreement unless a final, non-appealable judgment against
Director has been rendered in such action by the court of last resort (or by a
lower court if not timely appealed). At Director's request, such expenses will
be advanced by Corporation to Director as incurred before final resolution of
such action by the court of last resort; such expenses will be repaid by
Director if a final, non-appealable judgment in Corporation's favor is rendered
in such action by the court of last resort (or by a lower court if not timely
appealed).

         9. D&O Insurance.

                  (a) Subject to the provisions of paragraph 9(b) below, to the
extent is reasonably practical in the sole judgment of the Board of Directors,
the Corporation will maintain D&O Insurance in such amount as its Board of
Directors determines appropriate, insuring Director against any liability
arising out of Director's status as a director of Corporation, regardless of
whether Corporation has the power to indemnify Director against such liability
under applicable law.

                  (b) Corporation will not be required to purchase or maintain
D&O Insurance if the Board of Directors of Corporation determines, after
diligent inquiry, that (1) such insurance is not available; or (2) the premiums
for available insurance are disproportionate to the amount of coverage and to
the premiums paid by other corporations similarly situated. The Board of
Directors of Corporation will, at least annually, in good faith review its
decision with respect to the maintenance of D&O Insurance and will purchase such
insurance at any time that the conditions of the first sentence of this
paragraph 9(b) do not apply. In the event Corporation determines not to
purchase, renew or replace its D&O Insurance, it will as soon as practicable
provide written notice of such determination to Director; specifying the date
and time any in force D&O Insurance will expire.

                  (c) The parties will cooperate to obtain advances of Expenses,
indemnification payments and consents from D&O Insurance carriers in any Covered
Matter to the full extent of applicable D&O Insurance. The existence of D&O
Insurance coverage will not diminish or limit Corporation's obligation to make
indemnification payments to Director. Amounts paid directly to Director with
respect to a Covered Matter by Corporation's D&O Insurance carriers will be
credited to the amounts payable by Corporation to Director under this Agreement.

                                      -7-
<PAGE>

         10. Limitations of Actions; Limitation of Liability. No action will be
brought by or on behalf of Corporation against Director or Director's heirs or
personal representatives relating to Director's service as a director, after the
expiration of one year from the date Director ceases (for any reason) to serve
as a Director of Corporation, and any claim or cause of action of Corporation
will be extinguished and deemed released unless asserted by the filing of a
legal action before the expiration of such period.

         11. Rights Not Exclusive. The indemnification provided to Director
under this Agreement will be in addition to any indemnification provided to
Director by any law, agreement, Board resolution, provision of the Certificate
of Incorporation or Bylaws of Corporation or otherwise.

         12. Subrogation. Upon payment of any Indemnified Amount under this
Agreement, Corporation will be subrogated to the extent of such payment to all
of Director's rights of recovery therefor and Director will take all reasonable
actions requested by Corporation (at no cost or penalty to Director) to secure
Corporation's rights under this paragraph 12 including executing documents.

         13. Continuation of Indemnity. All of Corporation's obligations under
this Agreement will continue as long as Director is subject to any actual or
possible Covered Matter, notwithstanding Director's termination of service as a
director.

         14. Amendments. Neither Corporation's Certificate of Incorporation nor
its Bylaws will be changed to increase liability of directors or to limit
Director's indemnification. Any repeal or modification of Corporation's
Certificate of Incorporation or Bylaws or any repeal or modification of the
relevant provisions of any applicable law will not in any way diminish any of
Director's rights or Corporation's obligations under this Agreement. This
Agreement cannot be amended except with the written consent of Corporation and
Director.

<PAGE>
                                       

         In connection with the foregoing, Westmark commenced an action (the
"Declaratory Judgment Action") in Palm Beach County Circuit Court, Case No. 98
005545 AG, on June 23, 1998, The controversies with respect to the Agreements,
securities and Promissory Note described in items 1 through 6 above and set
forth in the Declaratory Judgment Action are collectively referred to as the
"Disputes."

         The parties desire to resolve the Disputes and any other outstanding
issues among them, and for that purpose are entering into this Exchange
Agreement.

         For valuable consideration mutually exchanged, the parties to this
Agreement, intending to be legally bound, agree as follows:

         1. Unless otherwise provided by the terms of this Agreement, the
execution and delivery of the instruments and documents provided for in this
Agreement are to take place simultaneously with its execution and delivery.

         2. Immediately after entering into this Agreement, Westmark shall
voluntarily dismiss the Declaratory Judgment Action. Westmark and MIOA shall
exchange mutual general releases (the "Mutual Releases") with each other, which
releases shall except only those obligations provided for in this Exchange
Agreement and Exhibits E, H, I, J and K attached to it. The forms of the Mutual
Releases are attached to this Agreement as Composite Exhibit G.

         3. In satisfaction of the Promissory Note, Westmark hereby assigns and
delivers all of its interest in 172,750 shares of the Series B Preferred Stock

consents to the modifications to the terms and conditions of the Series B
Preferred Stock as set forth in the Series B Articles of Amendment. As between
the parties, all terms and conditions of the Series B Preferred Stock shall be
governed by the Series B Articles of Amendment upon execution and delivery of
this Agreement, and such terms shall be deemed contractually so modified as of

         6. Simultaneously with the execution of this Agreement Westmark and
MIOA agree that the 200,000 shares of Series C Preferred Stock shall be
converted into 350,000 shares of Westmark common stock (the "New Westmark Common
Stock"). Upon conversion of the Series C Preferred Stock MIOA shall have no
rights or claims whatsoever relating to or arising from the Series C Preferred
Stock. Westmark agrees that upon receipt of an opinion of counsel retained by
MIOA, which counsel is reasonably acceptable to Westmark, stating that the Old
Westmark Common Stock and the New Westmark Common Stock may be sold by MIOA
without registration under the Securities Act of 1933, as amended, in reliance
on Rule 144 promulgated thereunder and that the requirements of paragraphs (c),
(e), (f) and (h) of Rule 144 do not apply to such sale by virtue of paragraph
(k) of Rule 144, Westmark shall authorize its transfer agent to rely upon such
opinion of counsel for purposes of issuing new certificates representing the Old
Westmark Common Stock and the New Westmark Common Stock without any restrictive
legend thereon or the placement in its records of any stop order related
thereto. The law firm of Mirkin & Woolf, P.A. shall be deemed reasonably
acceptable to Westmark for purposes of the preceding sentence.

         7. MIOA hereby irrevocably waives any and all rights to payment of
Series C Preferred Stock unpaid accrued dividends.

         8. Simultaneously with the execution of this Agreement, Westmark shall
issue to MIOA a warrant for the purchase of 100,000 shares of the common stock
of Westmark, at an exercise price of $3.25 per share, exercisable for two years
from the date of this Agreement, which warrant shall be in the form attached
hereto as Exhibit I.

         9. (a) "Adjusted Fully Diluted Earnings Per Share" means fully diluted
earnings per share based upon the consolidated net income of the Company
calculated in accordance with generally accepted accounting principles, as
reported by Westmark in its relevant filings with the Securities and Exchange
Commission pursuant to the reporting requirements of the Securities Exchange Act
of 1934, eliminating gains and losses from sales, exchanges and other
dispositions or write-downs of assets not in the ordinary course of Westmark's
mortgage business (including, without limitation, those arising from this
Agreement), and any other nonrecurring items, regardless of whether categorized
as an extraordinary item and other non-cash expenses. For purposes of this
calculation, fully diluted shares shall exclude any warrants held by MIOA.

                  (b) If Westmark's Adjusted Fully Diluted Earnings Per Share
for the year ended December 31, 1998 are less than $0.40, MIOA shall have the

Put") at a purchase price of the greater of $4.82 per share or Market Price per
share (as defined in the next sentence) on the last business day of 1998 (the

Option may not be exercised in satisfaction of transactions other than the 1998
MIOA Put, the First 1999 MIOA Put, or the Second 1999 MIOA Put. The Westmark

         12. Greenberg Traurig, P.A. shall initially act as Escrow Agent

any time resign hereunder by giving written notice of its resignation to all
parties hereto at least thirty (30) days prior to the date specified for such
resignation to take effect, and upon the effective date of such resignation, all
cash, documents and all other property (collectively the "Property") then held
by the Escrow Agent hereunder shall be delivered by it to such persons as may be
designated in writing by all parties hereto, whereupon all its prospective
obligations as Escrow Agent hereunder shall cease and terminate. The Escrow
Agent's sole responsibility thereafter shall be to keep safely all property then
held by it and to deliver same to a person designated by all parties hereto or
in accordance with the directions of a final order or judgment of a court of
competent jurisdiction. In addition, the Escrow Agent shall be discharged of its
prospective duties and obligations hereunder upon its interpleading in a court
of competent jurisdiction all of

submit to the personal jurisdiction of said court (but solely for the purpose of
implementing this Agreement) and waive all rights to contest said jurisdiction.

Escrow Agent for all its fees, costs and expenses in connection herewith,
including reasonable counsel fees. Westmark and MIOA shall be jointly and
severally obligated to indemnify the Escrow Agent and hold it harmless against

securities, cash, instruments, documents or any other property referred to
herein, unless the same shall have first been received by the Escrow Agent
pursuant to this Agreement. MIOA acknowledges that the Escrow Agent is counsel
for Westmark and agrees that no action taken by the Escrow Agent under this
Agreement shall affect or impair the right of the Escrow Agent to represent such
party(ies) in any matter, including an interpleader action pursuant to this
Agreement.

shall remain confidential until the parties simultaneously issue press releases

         WHEREAS, WGHI and MIOA (formally Heart Labs of America, Inc.) entered
into a Stock Purchase Agreement on or about November 21, 1995 together with

         WHEREAS, from time to time, since November 27, 1995, MIOA has provided
additional financing to WGHI in the approximate sum of One Million Nine Hundred
Fifty-Three Thousand Dollars ($1,953,000) and;

         WHEREAS, various disputes have arisen by and between the parties with

         NOW, THEREFORE, in consideration of the terms and conditions

<PAGE>


                                                                               2

                           more than $3,000,000 in Additional Capitalization by
                           March 15, 1997, MIOA shall receive a cash payment of
                           $300,000 on March 28, 1997.

                           (ii) WGHI shall execute a promissory note pursuant to
                           the schedule set forth on Exhibit "A" which is

                           ten percent (10%) per annum. Payments of principal
                           and interest shall be amortized equally over ten (10)
                           years, with payments commencing July 31, 1997. All
                           unpaid principal and interest shall be due and
                           payable no later than three (3) years from the date
                           of execution of this Agreement. The form of the
                           promissory note is attached hereto as Exhibit "B" and
                           incorporated herein. On the Closing Date an
                           amortization schedule will be prepared, attached
                           hereto as Exhibit "C" and incorporated herein.

                           (iii) Said promissory note shall also provide for a
                           principal reduction in the sum of $500,000 in the
                           event of the sale or disposition by WGHI of its

<PAGE>
                           wholly owned subsidiary, Green World Technologies,
                           Inc. prior to the maturity date of the note,
                           provided, however, that WGHI shall have received a

                           disposition. MIOA shall be entitled to all cash
                           received by WGHI up to $500,000. Said principal
                           reduction will occur contemporaneously with the
                           closing of the sale or disposition of Green World
                           Technologies, Inc. WGHI represents that it is
                           diligently pursuing the sale of Green World
                           Technologies, Inc. and that said company will not be
                           sold or disposed for less than fair market value. The
                           parties mutually agree that WGHI may elect to "spin
                           off" Green World Technologies in which event MIOA
                           shall not be entitled to a principal reduction unless
                           said "spin-off" shall result in the payment of cash
                           to WGHI.

                           (iv) Said promissory note shall further provide that
                           if prior to the maturity date of the note, WGHI sell
                           its note receivable or other collateral resulting
                           from the Green World Technologies, Inc. sale, or
                           disposition, the balance of the MIOA promissory note
                           shall be paid in full to the extent of the proceeds
                           received from the sale of said note receivable or
                           other collateral.

                           (v) Said promissory note may be pre-paid in part or
                           in full by WGHI without penalty.

                           (vi) Said promissory note shall be secured by a
                           mortgage on the real property described on Exhibit
                           "D" attached hereto and incorporated herein and if
                           necessary, by an assignment by WGHI to MIOA of the
                           Green World Technologies' note receivable or other
                           collateral referred to hereinabove, or a pledge of
                           the shares of Green World Technologies stock retained

                           rights or voting rights with respect to the
                           collateral in the absence of a default by WGHI. The
                           value of the security shall not exceed the
 
                                        3

                  B.       MIOA shall be entitled to the first $300,000 received
                           by WGHI with respect to the receipt of additional
                           capitalization by WGHI in the minimum amount of
                           $300,000 and maximum amount of $1.5 million. In the
                           event of the receipt of additional capitalization by

                           entitled to receive the first $500,000 of additional
                           capitalization above $1.5 million.

                  C.       MIOA shall be entitled to 50% of any additional
                           capitalization  received by WGHI in excess of $3 
                           million  until said  indebtedness shall have been 
                           paid in full.
<PAGE>
                  D.       MIOA shall also be entitled to 15% of the net cash
                           flow of WGHI in excess of operating expenses and
                           settlement payments on a consolidated basis during
                           the calendar year 1997 and 20% of said net cash flow
                           in the calendar year 1998.

                  E.       In the event WGHI shall sell either Westmark Mortgage
                           Corporation or Green World Technologies, Inc., wholly
                           owned subsidiaries of WGHI, or in the alternative
                           event of a "spin-off" of either subsidiary, MIOA
                           shall be entitled to receive and WHGI agrees to pay
                           to MIOA 50% of the cash proceeds received by WGHI
                           resulting from a sale or "spin-off."

         3. Closing Date. For the purpose of this Agreement, the closing Date
shall be June 30, 1997.

         4. Anti-Dilution and Default. WGHI and MIOA mutually covenant and agree
that Paragraph 1.6 of the Stock Purchase Agreement entered into by and between
the parties on November 21, 1995, as amended, is hereby deleted and terminated
in its entirety and shall be of no further force or effect. In the event of any
default with regard to the terms and conditions of the aforementioned Promissory
Note, WGHI shall issue to MIOA, shares of common stock of WGHI with a value
equivalent to the unpaid balance of principal and accrued interest pursuant to
said Promissory Note. The unpaid indebtedness as hereinabove set forth shall
also be secured by the preferred shares of MIOA stock owned by WGHI. In the
event of default as hereinabove set forth, said preferred shares shall be
assigned, transferred and conveyed to MIOA and WGHI shall have no further rights
to conversion.

         5. MIOA shall have demand registration rights with respect to the WGHI
shares of common stock owned by MIOA. Said demand registration rights shall be
incorporated in a separate agreement between WGHI and MIOA.

         6. After satisfaction of the indebtedness referred to hereinabove, MIOA
shall repurchase the shares of MIOA preferred and common stock owned by WGHI and
WGHI shall repurchase the shares of WGHI preferred and common stock owned by
MIOA. The purchase price for the preferred shares shall be the stated value and
the purchase price for the common shares shall be the closing bid price on the
day prior to the repurchase.

         7. Except as hereinabove amended, said Modified Agreement shall
continue in full force and effect.

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

FOR VALUE RECEIVED, the undersigned, WESTMARK GROUP HOLDINGS, INC., a Delaware
corporation having its principal offices ____________________________________
(the "Maker"), promises to pay to the order of MEDICAL INDUSTRIES OF AMERICA,

Maker and the Payee (the "Settlement Agreement"), a copy of which is attached
hereto and incorporated herein.

Payments on this Note shall be made as follows:

1 1. Principal and Interest. Payments of principal and interest shall be
amortized over one hundred twenty (120) equal consecutive monthly installments

shall be due and payable in full.

2 2. Late Fee. In the event that any payment of principal due under this Note is
not paid within thirty (30) days of its due date, the Maker shall pay to the
Payee a late fee equal to five percent (5%) of the amount of such late payment,
which shall be due immediately. Any interest or late fee due hereunder which is
not paid when due shall be automatically added to principal.

3 3. Voluntary Prepayments.  The Maker may at any time prepay this Note, in
whole or in part, from time to time, without premium or penalty.

4 4. Payments. Except to the extent otherwise provided herein, all payments of
principal, interest, fees and other amounts to be made by Maker hereunder shall
be made in immediately available funds to the Payee, at the above address unless
otherwise notifies in writing, not later than 2:00 p.m. on the date on which
such payment shall become due. If any payment hereunder shall be due and payable
on a day which is not a business day, such payment shall be deemed due on the
next following business day.


<PAGE>
The Maker, for itself and its successors and assigns, to the extent it may
lawfully do so, hereby expressly waives presentment, demand, protest, notice of
protest, diligence in collection or bringing suit and any and all rights of
setoff, deduction and counterclaim, and consents that the Payee may release or
surrender, exchange or substitute any personal property or other collateral now
held or which may hereafter be held as security for the payment of amounts due
hereunder without affecting the Maker's obligations hereunder.

This Note is entitled to the benefit of the security interests granted by the
maker to the Payee as set forth in Paragraph 1(a)(iv) of the Settlement
Agreement, which security interests are documented by a mortgage, security
agreement or other applicable method used to perfect security interests (the
"Security Agreements").

An "Event of Default" shall exist, and all amounts due hereunder shall become
immediately due and payable in full, (i) automatically in the case of the
occurrence of any Event of Default described below and (ii) at the election of
the Payee upon the occurrence of any other Event of Default:

A. The Maker shall fail to pay any principal or other sum due the Payee under
this Note within thirty (30) days when the same is due, whether at stated
maturity, by acceleration or otherwise;

B. Any default shall occur under a Security Agreement and remain uncured upon
the expiration of any applicable grace period provided for therein;

C. The Maker shall make a general assignment for the benefit of creditors, admit
is inability to pay its debt as they become due, be adjudicated bankrupt or
insolvent, file a petition in bankruptcy or seeking any arrangement,
composition, readjustment or similar relief under any present or future federal,
state or province law or regulation ("Debtor Relief Laws") or an answer admitted
or not contesting the material allegations of a petition filed against it in any
such proceeding, or seek, consent to or acquiesce in the appointment of a
trustee, receiver or other fiduciary for it or any of its assets;

D. Any proceeding against the Maker seeking an adjudication of bankruptcy or
insolvency or an agreement, composition, readjustment or similar relief under
any Debtor Relief Law shall remain undismissed or unstayed, or an appointment of
a trustee, receiver or other fiduciary for the Maker or any of its assets
without the consent or acquiescence of the Maker shall not be vacated, within
sixty (60) days after the commencement of such proceeding or the appointment of
such fiduciary;

                                       2

<PAGE>

Following an Event of Default, the Payee shall be entitled to exercise all
rights and remedies as it may have under this Note and otherwise at law or in
equity, including, without limitation, the rights and remedies of a secured
party. All of such rights and remedies shall be cumulative and may be exercised
from time to time, concurrently or separately and without any marshaling, n such
order as the Payee may determine. No delay or omission on the part of Payee in
exercising any such right or remedy shall operate as a waiver of such right or
remedy or any other right or remedy, nor shall any such delay or omission be
deemed to bar the exercise of any right or remedy at any future time. Any
amendment of this Note or waiver of any right or remedy with respect hereto
shall be effective only if set forth in a writing signed by both the holder of
this Note and the Maker. No waiver of any default shall affect the Payee's right
to exercise any right or remedy with respect to any different or subsequent
default.

If this Note shall not be paid when due and shall be placed by the holder hereof
in the hands of any attorney for collection, through legal proceedings or
otherwise, the non-prevailing party agrees to pay reasonable attorneys' fees to
the prevailing party in such action together with reasonable costs and expenses
of collection, including, without limitation, any such attorneys' fees, costs
and expenses relating to any dissolution, liquidation, insolvency, bankruptcy,
reorganization, readjustment of debt, receivership, attachment, levy,
foreclosure or similar proceedings affecting the Maker or any party to any
instrument or agreement securing this Note or any of their respective assets
("Related Proceedings"). All such amounts shall be added to principal as they
are incurred. Nothing in this Note shall be construed as preventing the Payee
from taking all lawful actions to protect its interests in the event that any
Related Proceedings should be instituted.

This Note shall be governed by and construed and enforced in accordance with the
laws of the State of Florida. The Maker hereby irrevocably consents and submits
to the jurisdiction of the courts sitting in Palm Beach County, Florida over the
enforcement of this Note or any collateral given by the Maker with respect to
the indebtedness under this Note, hereby waiving any objection to the venue of
such courts. The Maker hereby further waives personal service of process and
agrees that a summons and complaint commencing any proceeding in any such court
shall be properly served and shall confer personal jurisdiction if served by
registered or certified mail to the Maker at its address first set forth above
in this Note or at such other address for the Maker of which the holder of this
Note shall have received written notice mailed in similar manner by the Maker to
such holder at its address set forth in this Note or at such other address as
such holder may provide the Maker by mail in similar manner.

5. Assignment. Payee shall have the unconditional right to assign its rights
under this Note in its sole and absolute discretion.

                          ARTICLES OF INCORPORATION OF
                       MEDICAL INDUSTRIES OF AMERICA, INC.

         Pursuant to the provisions of Section 607.1006 of the Florida Business
Corporation Act (1993), the undersigned corporation adopts the following
Articles of Amendment to its Articles of Incorporation:

         1. The name of the corporation is Medical Industries of America, Inc.
(the "Corporation").

         2. The following amendment to the Articles of Incorporation was adopted
by the Directors of the Corporation without shareholder action since shareholder
action was not required under the Articles of Amendment, as amended. The
following amendment to the Articles of Incorporation was adopted by the
Directors of the Corporation by the Unanimous Written Consent of Directors of
the Corporation in Lieu of a Special Meeting dated September ___, 1998, in the
manner prescribed by Sections 607.1002 and 607.1006 of the Florida Business
Corporation Act:

         Section C.2 of ARTICLE III of the Articles of Incorporation of the
Corporation is hereby amended in its entirety to read as follows:

                  "2. Series B Preferred Stock:

                  a. Designation and Rank. Two hundred thousand (200,000)
         shares of the Corporation's authorized preferred stock, no par value,
         are hereby designated as "Series B Convertible Preferred Stock," all of
         which shares shall rank equally and be identical in all respects. The
         Series B Convertible Preferred Stock is sometimes referred to herein as
         the "Series B Preferred Stock."

                  b. Dividends.

                           i.     None.

                  c. Redemption.  The shares of Series B Preferred Stock shall 
         be subject to redemption as follows:

                           i. The Corporation shall have the right, in its
         sole discretion, upon receipt of a Notice of Conversion pursuant to
         Section 2.d., or earlier without receipt of any notice of conversion
         upon 10 days written notice (the "Notice of Redemption") to the holders
         of the Series B Preferred Stock, to redeem in whole or in part any
         shares of Series B Preferred Stock submitted for conversion,
         immediately prior to conversion, or otherwise outstanding and subject
         to a right of conversion.

                                       1
<PAGE>

                           ii. The Redemption Payment per Share for each
         redemption of the Series B Preferred Stock shall be at a stated value
         of $10.00 per share. The date of receipt by the Corporation of the
         Notice of Conversion or the date of mailing by the Corporation of a
         Notice of Redemption, as the case may be, shall be the "Date of
         Redemption." The Corporation shall have the right to satisfy its
         obligations to make the Redemption Payment per Share with shares of Old
         Westmark Common Stock or New Westmark Common Stock (as defined in the
         Exchange Agreement between the Corporation and Westmark Group Holdings,
         Inc. dated September 30, 1998) based upon the Weighted Average Market
         Price (as defined in the next two sentences) of Westmark Group
         Holdings, Inc. ("WGHI") common stock for the twenty business days
         preceeding the Date of Redemption. Market Price for purposes of this
         paragraph shall be the last reported sales price regular way or, in
         case no such reported sales takes place on such day, the average of the
         closing bid and asked prices regular way, on the principal national
         securities exchange in the United States on which WGHI common stock is
         listed or admitted to trading, or if it is not listed or admitted to
         trading on any such national securities exchange, the average of the
         highest reported bid and lowest reported asked price as furnished by
         the National Association of Securities Dealers, Inc. through its
         automated quotation system ("Nasdaq") or a similar organization if
         Nasdaq is no longer reporting such information. Weighted Average Market
         Price for purposes of this Paragraph shall be the quotient of the sum
         of the products of each of the last twenty business days' Market Price
         preceeding the Date of Redemption multiplied by the number of shares
         sold for each such day, divided by the total number of shares sold
         during the twenty business days. If less than all of the outstanding
         shares of the Series B Preferred Stock are redeemed at any time under
         this Section 2.c., then the shares of Series B Preferred Stock held by
         each holder of record shall be redeemed pro rata, according to the
         number of shares of Series B Preferred Stock held by such holder,
         subject, however, to such adjustment as may be equitably determined by
         the Corporation in order to avoid the redemption of fractional shares.

                           iii. The Corporation shall effect each such
         redemption by giving notice of its election to redeem, by facsimile
         within one (1) business day of receipt of a Notice of Conversion from a
         Subscriber, or upon the giving of a Notice of Redemption by the Company
         to a Subscriber, with a copy by two-day courier, to the holder of
         shares of Series B Preferred


                                       2
<PAGE>
         Stock submitted for the conversion at the address and facsimile number
         of such holder appearing in the Corporation's register for the Series B
         Preferred Stock. Such Notice of Redemption shall indicate whether the
         Corporation will redeem all or part of the shares of Series B Preferred
         Stock submitted for conversion and the applicable redemption price. The
         Corporation shall not be entitled to send any Notice of Redemption and
         begin the redemption procedure unless it has the full amount of the
         redemption price, in cash available in a demand or other immediately
         available account in a bank or similar financial institution on the
         date the redemption notice is sent to shareholders, or shares of
         Westmark Old Common Stock or Westmark New Common Stock based upon the
         Weighted Average Market Price (as defined in Section 2.c.ii.).

                           The Redemption Payment per Share shall be paid to the
         holder of shares of Series B Preferred Stock redeemed within ten (10)
         business days of the delivery of the Notice of Redemption to such
         holder; provided, however, that the Corporation shall not be obligated
         to deliver any portion of the Redemption Payment per Share unless
         either the certificate(s) evidencing the shares of Series B Preferred
         Stock are delivered to the Corporation or its transfer agent or the
         holder notifies the Corporation or its transfer agent that such
         certificate(s) have been lost, stolen, or destroyed and executes an
         agreement satisfactory to the Corporation to indemnify the Corporation
         from any loss incurred by it in connection with such certificate(s).

                  d. Conversion. The holders of shares of Series B Preferred 
         Stock shall have conversion rights as follows:

                           i. Upon the earlier of the filing of the WGHI 1999
         Form 10-KSB or the sale of all the Old Westmark Common Stock and the
         New Westmark Common Stock by the Corporation, each Share of Series B
         Preferred Stock will be convertible, at the option of the holder
         thereof, for a period of ten (10) years from the date of issuance,
         exercisable by giving written notice to the Corporation not less than
         thirty (30) days prior to such Conversion Date (the "Notice of
         Conversion"), subject to adjustment as provided in the following
         paragraphs, into that number of shares of Common Stock equal to $10.00
         (the "Stated Value") divided by the average of the Common Stock's bid
         and ask price as listed by NASDAQ for the thirty (30) business days
         prior to receipt by the Corporation of receipt of a Notice of
         Conversion from the holder (the "Conversion Ratio").
 
                                        3
<PAGE>
                           ii. In the event that any dividends on the
         outstanding Common Stock shall have been declared prior to, and shall
         be payable subsequent to the conversion of such Series B Preferred
         Stock, such dividends shall not be payable on any Common Stock into
         which such Series B Preferred Stock shall have been converted.

                           iii. The Board of Directors of the Corporation
         shall reserve a sufficient number of shares of Common Stock for
         issuance upon conversion of shares of Series B Preferred Stock into
         Common Stock as aforesaid.

                           iv. In the event that the Corporation shall at any
         time or from time to time change the then outstanding shares of Common
         Stock into the same or different number of shares or units of any other
         class or classes of capital stock or other securities, then,
         notwithstanding the provisions thereof, from and after the first such
         change each holder of shares of Series B Preferred Stock shall, upon
         the conversion of such shares, be entitled to receive that number of
         shares or units of such other stock or security which such holder would
         then have if he (1) had, prior to the first such change, converted into
         shares of Common Stock, pursuant to the provisions hereof, a number of
         shares of Series B Preferred Stock equal to the number then being
         converted by him, and (2) had held the shares which he would have so
         received or any other shares or units into which the same would
         subsequently have been changed if they had then been outstanding until
         the day of the conversion of the shares of Series B Preferred Stock
         then being converted.

                           v. The Conversion Ratio shall be appropriately
         adjusted to eliminate any dilution of holders of Series B Preferred
         Stock by reason of any of the following events: (1) if the Corporation
         pays a dividend or makes a distribution in shares of Common Stock or
         other class of capital stock to holders of Common Stock, or (2) if the
         Corporation subdivides its outstanding Common Stock into a greater
         number of shares or combines its outstanding Common Stock into a small
         number of shares.

                  e.     Voting and Preemptive Rights.

                           i. Except as otherwise specifically provided by the
         Florida Business Corporation Act, the holders of Series B Preferred
         Stock shall not be entitled to vote on any matters required or
         permitted to be submitted to stockholders of the Corporation for their
         approval. Notwithstanding the foregoing, the affirmative vote or
         written consent of the holders of a majority of the Series B Preferred
         Stock outstanding from

                                       4
<PAGE>
         time to time shall be required for the amendment of the Corporation's
         Articles of Incorporation to authorize the issuance of additional
         shares of Series B Preferred Stock.

                            ii. The holders of shares of Series B Preferred
         Stock shall have no preemptive rights in connection with any security
         of any kind which the Corporation shall at any time issue or be
         authorized to issue.

                   f. Liquidation. The Series B Preferred Stock shall be
         preferred upon liquidation over the Common Stock and any other class or
         classes of stock of the Corporation (but shall rank in parity with any
         other class of preferred stock of the Corporation that so provides), so
         that the holders of shares of Series B Preferred Stock shall be
         entitled to be paid the Stated Value before any distribution is made to
         the holders of the Common Stock and junior stock upon the voluntary or
         involuntary dissolution, liquidation or winding-up of the Corporation.
         If, upon any such liquidation, dissolution or winding-up of the
         Corporation, its net assets shall be insufficient to permit the payment
         in full of the amounts to which the holders of all outstanding shares
         of Series B Preferred Stock are entitled as above provided, the entire
         net assets of the Corporation remaining shall be distributed among the
         holders of shares of Series B Preferred Stock in amounts proportionate
         to the full preferential amounts to which they and holders of shares of
         preferred stock ranking in parity with the Series B Preferred Stock as
         to rights and preferences are respectively entitled. For the purpose of
         this Section f., the voluntary sale, lease, exchange or transfer, for
         cash, shares of stock, securities or other consideration, of all or
         substantially all the Corporation's property or assets to, or its
         consolidation or merger with, one or more corporations shall not be
         deemed to be a liquidation, dissolution or winding-up of Corporation,
         voluntary or involuntary.

                   g. Reacquired Shares. Any shares of Series B Preferred Stock
         that have been converted into shares of Common Stock or issued and
         subsequently reacquired by the Corporation or redeemed or purchased or
         otherwise acquired by the Corporation in any manner whatsoever shall be
         retired and canceled promptly after the acquisition thereof. All such
         Shares upon their cancellation shall become authorized but unissued
         shares of the preferred stock, no par value, of the Corporation and may
         be reissued as part of a new series of preferred stock of the
         Corporation to be created by resolution or resolutions of the Board of
         Directors, subject to the conditions and restrictions on issuance set
         forth in the Corporation's Articles of Incorporation."

         Section 2.01: Duration of Warrant. The Warrantholder may exercise this
Warrant at any time and from time to time after 9:00 A.M., Florida time, on the

         Section 2.02: Exercise of Warrant.

         (a) The Warrantholder may exercise this Warrant, in whole or in part,
by presentation and surrender of this Warrant to the Corporation at its
principal corporate office or at the office of its stock transfer agent, if any,
with the subscription form attached hereto as Exhibit A (the "Subscription
Form") duly executed and accompanied by payment of the full Exercise Price for
each Warrant Share to be purchased.

         (b) Upon receipt of this Warrant with the Subscription Form fully
executed and accompanied by payment of the aggregate Exercise Price for the
Warrant Shares for which this Warrant is then being exercised, the Corporation
shall cause to be issued certificates for the total number of whole shares of
Common Stock for which this Warrant is being exercised in such denominations as
are requested for delivery to the Warrantholder registered in the name of the
Warrantholder or its nominee, and the Corporation shall thereupon deliver such
certificates to the Warrantholder. The Warrantholder shall be deemed to be the
holder of record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Corporation shall then be
closed or that certificates representing such shares of Common Stock shall not
then be actually delivered to the Warrantholder.

         (c) In lieu of exercising the Warrant in the manner set forth in
sub-paragraph 2.03(a) and (b) above, this Warrant may be exercised without
payment of any other consideration, commission, or remuneration, by presentation
and surrender of the Warrant to the Corporation, together with a written notice
of the Warrantholder's intention to effect a cashless exercise ("Notice of
Cashless Exercise") and the Subscription Form, duly executed. In the event of a
Cashless Exercise, the number of shares to be issued in exchange for the Warrant
will be computed by multiplying the number of Warrant Shares to which the
Warrantholder would otherwise be entitled (upon payment of the aggregate
Exercise Price) by a fraction, the numerator of which shall be the difference
between the Closing Bid Price (as defined in the next sentence) and the Warrant
Exercise Price, and the denominator of which shall be the Closing Bid Price. The
Closing Bid Price means the closing bid price per share of the Common Stock on
the last business day prior to the date of receipt of the Warrant, the Notice of
Cashless Exercise, and the Subscription Form, on the principal national
securities exchange in the United States on which the Common Stock is listed or
admitted to trading, or if the Common Stock is not listed or admitted to trading
on any such national securities exchange, the average of the highest reported
bid and lowest reported asked price, on such day, as furnished by the National
Association of Securities Dealers, Inc. ("Nasdaq") through its automated
quotation system or a similar organization if Nasdaq is no longer reporting such
information.

         (d) In case the Warrantholder shall exercise this Warrant with respect
to less than all of the Warrant Shares that may be purchased under this Warrant,
the Corporation shall execute a new warrant in the form of this Warrant for the
balance of such Warrant Shares and deliver such new warrant to the
Warrantholder.

         (e) The Corporation shall pay any and all stock transfer and similar
taxes which may be payable in respect of the issue of any Warrant Shares to the
Warrantholder.

         Section 2.03: Reservation of Shares. The Corporation hereby agrees that
at all times there shall be reserved for issuance and delivery upon exercise of
this Warrant such number of shares of Common Stock from time to time issuable
upon exercise of this Warrant. All such shares shall be duly authorized, and
when issued upon such exercise, shall be validly issued, fully paid and
nonassessable, free and clear of all liens, security interests, charges and
other encumbrances or restrictions on sale and free and clear of all preemptive
rights.

         Section 2.04: Fractional Shares. The Corporation shall not be required
to issue any fraction of a share of its capital stock in connection with the
exercise of this Warrant, and in any case where the Warrantholder would, except
for the provisions of this Section 2.04, be entitled under the terms of this
Warrant to receive a fraction of a share upon the exercise of this Warrant, the
Corporation shall, upon the exercise of this Warrant and receipt of the Exercise
Price, issue the largest number of whole shares purchasable upon exercise of
this Warrant. The Corporation shall, in lieu of issuing any fractional share pay
the Warrantholder a sum in cash equal to the fair market value of any such
fractional interest as determined in good faith by the Corporation.


                                   ARTICLE III

                      ADJUSTMENT OF SHARES OF COMMON STOCK
                        PURCHASABLE AND OF EXERCISE PRICE

         The Exercise Price and the number and kind of Warrant Shares shall be
subject to adjustment from time to time upon the happening of certain events as
provided in this Article III.

         Section 3.01:  Mechanical Adjustments.

         (a) In case the Corporation shall at any time or from time to time
after the date hereof (i) pay any dividend, or make any distribution, on the
outstanding shares of Common Stock (or Common Stock Equivalents) in shares of
Common Stock, (ii) subdivide the outstanding shares of Common Stock, (iii)
combine the outstanding shares of Common Stock into a smaller number of shares
or (iv) issue by

                                          WGHI-MIOA\Warrant\DPF\EXECUTION D

reclassification of the shares of Common Stock any shares of capital stock of
the Corporation, then and in each such case, the Exercise Price in effect
immediately prior to such event or the record date therefor, whichever is
earlier, shall be adjusted so that the Warrantholder shall be entitled to
receive the number and type of shares of Common Stock which such Warrantholder
would have owned or have been entitled to receive after the happening of any of
the events described above, had such Warrant been converted into Common Stock
immediately prior to the happening of such event or the record date therefor,
whichever is earlier. An adjustment made pursuant to this Section 3.01(a) shall
become effective (x) in the case of any such dividend or distribution,
immediately after the close of business on the record date for the determination
of holders of shares of Common Stock entitled to receive such dividend or
distribution, or (y) in the case of such subdivision, reclassification or
combination, at the close of business on the day upon which such corporate
action becomes effective.

         (b) If the Corporation shall take a record of the holders of its Common
Stock for the purpose of entitling them to receive a dividend or other
distribution and shall thereafter, and before such dividend or distribution is
paid or delivered to stockholders entitled thereto, legally abandon its plan to
pay or deliver such dividend or distribution, then no adjustment in the Exercise
Price then in effect shall be made by reason of the taking of such record, and
any such adjustment previously made as a result of the taking of such record
shall be reversed.

         (c) As used in this Section 3.01 the term "Common Stock" shall mean and
include the Corporation's authorized Common Stock, par value $0.005 per share,
as constituted on the date hereof, and shall also include any capital stock of
any class of the Corporation thereafter authorized which shall neither be
limited to a fixed sum or percentage in respect of the rights of the holders
thereof to participate in dividends nor be entitled to a preference in the
distribution of assets upon the voluntary or involuntary liquidation,
dissolution or winding up of the Corporation.

         (d) In the case of a Sale of the Corporation or a proposed
reorganization of the Corporation or a proposed reclassification of the capital
stock of the Corporation (except a transaction for which provision for
adjustment is otherwise made in this Section 3.01), the Warrant shall thereafter
be exercisable into the number of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon exercise of such Warrant would have been entitled
upon such Sale of the Corporation, reorganization or reclassification; and, in
any such case, appropriate adjustment (as determined by the Board of Directors)
shall be made in the application of the provisions herein set forth with respect
to the rights and interest thereafter of the holders of the Warrant, to the end
that the provisions set forth herein (including provisions with respect to
changes in and other adjustments of the applicable 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 exercise of
the Warrant. The Corporation shall not effect any such Sale of the Corporation
unless prior to or simultaneously with the consummation thereof

                                       5
<PAGE>

                                          WGHI-MIOA\Warrant\DPF\EXECUTION D

the successor Corporation or purchaser, as the case may be, shall assume by
written instrument the obligation to deliver to the Warrantholder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
each such holder is entitled to receive.

         (e) Whenever the Exercise Price payable upon exercise of each Warrant
is adjusted pursuant to paragraph (a) of this Section 3.01, the Warrant Shares
shall simultaneously be adjusted by multiplying the number of Warrant Shares
initially issuable upon exercise of each Warrant (as set forth on the front page
of this Warrant) by $3.25 and dividing the product so obtained by the Exercise
Price, as adjusted.

         (f) No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least one cent ($.01) in
such price; provided, however, that any adjustments which by reason of this
paragraph (h) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section
3.01 shall be made to the nearest cent or to the nearest one-hundredth of a
share, as the case may be. Notwithstanding anything in this Section 3.01 to the
contrary, the Exercise Price shall not be reduced to less than the then existing
par value of the Common Stock as a result of any adjustment made hereunder.

         (g) In the event that at any time, as a result of any adjustment made
pursuant to Section 3.01(a), the Warrantholder thereafter shall become entitled
to receive any shares of capital stock of the Corporation other than Common
Stock, thereafter the number of such other shares so receivable upon exercise of
any Warrant shall be subject to adjustment from time to time in a manner and on
terms as nearly equivalent as practicable to the provisions with respect to the
Common Stock contained in Section 3.01(a).

         Section 3.02: Notices of Adjustment. Whenever the number of Warrant
Shares or the Exercise Price is adjusted as herein provided, the Corporation
shall prepare and deliver forthwith to the Warrantholder a certificate signed by
its President or a Vice President, or by the Treasurer or an Assistant Treasurer
or the Secretary or an Assistant Secretary, setting forth the adjusted number of
shares purchasable upon the exercise of this Warrant and the Exercise Price of
such shares after such adjustment, setting forth a brief statement of the facts
requiring such adjustment and setting forth the computation by which adjustment
was made.

         Section 3.03: Form of Warrant After Adjustments. The form of this
Warrant need not be changed because of any adjustments in the Exercise Price or
the number or kind of the Warrant Shares, and Warrants theretofore or thereafter
issued may continue to express the same price and number and kind of shares as
are stated in this Warrant, as initially issued.

         Section 3.04: Treatment of Warrantholder. Prior to due presentment for
registration of transfer of this Warrant, the Corporation may deem and treat the
Warrantholder as the absolute owner of this Warrant (notwithstanding any
notation of ownership or other writing hereon) for all purposes and shall not be
affected by any notice to the contrary.

                                   ARTICLE IV

              OTHER PROVISIONS RELATING TO RIGHTS OF WARRANTHOLDER

         Section 4.01: No Rights as Shareholders; Notice to Warrantholders.
Nothing contained in this Warrant shall be construed as conferring upon the
Warrantholder the right to vote or to receive dividends or to consent or to
receive notice as a shareholder in respect of any meeting of shareholders for
the election of directors of the Corporation or of any other matter, or any
rights whatsoever as shareholders of the Corporation. The Corporation shall give
notice to the Warrantholder by certified mail if at any time prior to the
expiration or exercise in full of the Warrants, any of the following events
shall occur:

         (a) the Corporation shall declare any dividend or distribution with
respect to its capital stock;

         (b) a dissolution, liquidation or winding up of the Corporation shall
be proposed; or

         (c) a capital reorganization or reclassification of the capital stock
of the Corporation, any consolidation or merger of the Corporation with or into
another corporation, any transaction or series of transactions in which more
than fifty percent (50%) of the voting securities of the Corporation are
transferred to another person, or of any sale or conveyance to another
corporation of the property of the Corporation as an entirety or substantially
as an entirety.

         Such giving of notice shall be initiated at least ten Business Days
prior to the date fixed as a record date or effective date or the date of
closing of the Corporation's stock transfer books for the determination of the
shareholders entitled to such dividend or distribution, or for the determination
of the shareholders entitled to vote on such proposed merger, consolidation,
sale, conveyance, dissolution, liquidation or winding up. Such notice shall
specify such record date or the date of closing the stock transfer books, as the
case may be.

         Section 4.02: Lost, Stolen, Mutilated or Destroyed Warrants. If this
Warrant is lost, stolen, mutilated or destroyed, the Corporation may, on such
reasonable terms as to indemnity or otherwise as it may in its reasonable
discretion impose (which shall, in


                                       7

the case of a mutilated Warrant, include the surrender thereof), issue a new
Warrant of like denomination and tenor as, and in substitution for, this
Warrant.


                                    ARTICLE V

                             SPLIT-UP, COMBINATION,
                        EXCHANGE AND TRANSFER OF WARRANTS

         Section 5.01: Split-Up, Combination, Exchange and Transfer of Warrants.
Subject to the provisions of Section 5.02 hereof, this warrant may be split up,
combined or exchanged for another Warrant or Warrants containing the same terms
to purchase a like aggregate number of Warrant Shares. If the Warrantholder
desires to split up, combine or exchange this Warrant, the Warrantholder shall
make such request in writing delivered to the Corporation and shall surrender to
the Corporation this Warrant and any other Warrants to be so split-up, combined
or exchanged. Upon any such surrender for a split-up, combination or exchange,
the Corporation shall execute and deliver to the person entitled thereto a
Warrant or Warrants, as the case may be, as so requested. The Corporation shall
not be required to effect any split-up, combination or exchange which will
result in the issuance of a Warrant entitling the Warrantholder to purchase upon
exercise a fraction of a share of Common Stock or a fractional Warrant. The
Corporation may require such Warrantholder to pay a sum sufficient to cover any
tax or governmental charge that may be imposed in connection with any split-up,
combination or exchange of Warrants.

         Section 5.02: Transfer. This Warrant and all rights hereunder may be
sold, transferred or otherwise disposed of, in whole or in part, to any person
in accordance with and subject to the provisions of the Securities Act of 1933,
as amended (the "Securities Act"), and the rules and regulations promulgated
thereunder. Upon the delivery to the Corporation at its principal corporate
office of this Warrant along with a duly completed Assignment Form substantially
in the form of Exhibit B hereto, the Corporation shall execute and deliver a new
Warrant in the form of this Warrant, but registered in the name of the
transferee, to purchase the number of Warrant Shares assigned to the transferee.
In case the Warrantholder shall assign this Warrant with respect to less than
all of the Warrant Shares that may be purchased under this Warrant, the
Corporation shall execute a new warrant in the form of this Warrant for the
balance of such Warrant Shares and deliver such new warrant to the
Warrantholder.

         Section 5.03: Restrictive Legend. Each Warrant Share issued upon
exercise of this Warrant shall bear a legend containing the following words:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE
                  SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
                  SOLD,

    TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH SUCH ACT."

The requirement that the above legend be placed upon certificates evidencing any
such securities shall cease and terminate upon the earliest of the following
events: (i) when such shares are transferred in an underwritten public offering,
(ii) when such shares are transferred pursuant to Rule 144 under the Securities
Act or (iii) when such shares are transferred in any other transaction if the
seller delivers to the Corporation an opinion of its counsel, which counsel and
opinion shall be reasonably satisfactory to the Corporation, or a "no-action"
letter from the Staff of the Securities and Exchange Commission, in either case
to the effect that such legend is no longer necessary in order to protect the
Corporation against a violation by it of the Securities Act upon any sale or
other disposition of such shares without registration thereunder. Upon the
occurrence of such event, the Corporation, upon the surrender of certificates
containing such legend, shall, at its own expense, deliver to the holder of any
such securities as to which the requirement for such legend shall have
terminated, one or more new certificates evidencing such securities not bearing
such legend.

                               SECURITY AGREEMENT


<PAGE>
                               SECURITY AGREEMENT
                               ------------------

         THIS AGREEMENT (the "Agreement") is made this 30th day of September,
1998, by and between MEDICAL INDUSTRIES OF AMERICA, INC. a Florida corporation
("MIOA"), and WESTMARK GROUP HOLDINGS, INC., a Delaware corporation
("Westmark").

         Q. This Security Agreement is provided for in Paragraph 9(f) of the
Exchange Agreement of even date between Westmark and MIOA (the "Exchange
Agreement") of which this Agreement appears as an exhibit. All capitalized terms
in this Security Agreement shall have the same meaning as set forth in the
Exchange Agreement unless the context requires otherwise. Pursuant to Paragraph
9(f) of the Exchange Agreement, Westmark has agreed to secure its potential
obligations to MIOA pursuant to Paragraph 9 of the Exchange Agreement (the
"Potential Debt") with (1) the remaining 27,250 shares of Series B Preferred
Stock owned by Westmark (the "Stock") and (2) a Contingency Reserve Fund
described herein.

         R. To secure payment of the Potential Debt, Westmark has agreed to
(grant to MIOA a security interest in the (1) the Stock, and (2) the Contingency
Reserve Fund (collectively the "Collateral").

                               TERMS OF AGREEMENT
                               ------------------

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

         1. To secure (a) payment of the Debt, Westmark hereby grants to MIOA
a security interest in all of the Collateral, including the Contingency Reserve
Fund described as follows: On October 31, 1998, and on the last day of each
month thereafter through March of 1999, WGHI shall deposit the sum of $50,000
each month in an interest bearing money market account as a contingency reserve
fund for prospective repurchase obligations set forth in Paragraphs 9(b), (c)
and (d) of the Exchange Agreement between Westmark and MIOA of even date. Said
contingent repurchase obligations shall also be secured by the remaining 27,250
shares of Series B Preferred Stock owned by Westmark with an agreed fixed value
of $272,500. Westmark will not be obligated to make further deposits into the
reserve account unless and until Westmark becomes obligated to make any of the
contingent repurchases pursuant to paragraph 9(b), (c) and (d) of the Exchange
Agreement. If, as a result of any repurchase of common stock by Westmark, the
reserve account balance, including the value of the aforementioned Preferred
shares (calculated at $10.00 per share), falls below $333,000, Westmark will
reinstate monthly deposits in the sum of $50,000, or such lesser amount as may
be required, until the reserve account balance, including

<PAGE>

MIOA Preferred Stock owned by Westmark is equal to $333,000. Interest accrued on
the Contingency Reserve Account during periods of time when the balance equals
or exceeds $333,000 shall be paid to Westmark immediately upon receipt.

         2. The security interest in the Collateral shall be a first lien
security interest subordinate to no other liens.

         3. The original Series B Preferred Stock certificates and the
Contingency Reserve Fund representing all of the Collateral shall be held on
behalf of MIOA by Greenberg Traurig, P.A., ("Greenberg Traurig") 777 S. Flagler
Drive, Suite 310E, West Palm Beach, Florida (the "Escrow Agent"). Simultaneously
with the execution and delivery of this Agreement, Westmark shall deliver to the
Escrow Agent all original certificates representing the Stock issued in the name
of Westmark, along with stock powers endorsed in blank. MIOA may, upon request
to the Escrow Agent and delivery by the Escrow Agent of the appropriate
Collateral to MIOA, exchange the certificates representing the Stock for
certificates of smaller or larger denominations for any purpose consistent with
the terms of this Security Agreement.

         4. So long as there is no failure to make due and punctual payment of
the Potential Debt to MIOA nor any other continuing event which would constitute
an Event of Default, as hereinafter defined, under this Agreement:

                  (a) Westmark shall be entitled to exercise any and all voting
and/or consensual rights and powers relating or pertaining to the Stock or any
part thereof.

                  (b) Westmark shall be entitled to receive and retain any and
all stock and/or liquidating dividends, distributions in property, returns of
capital or other distributions made on or in respect of the Stock, whether
resulting from a subdivision, combination or reclassification of the outstanding
capital stock of MIOA or received in exchange for the Stock or any part thereof,
or as a result of any merger, consolidation, acquisition or other exchange of
assets to which MIOA may be a party or otherwise, and any and all cash and other
property received in payment of the principal of or in redemption of or in
exchange for any Stock (either at maturity, upon call for redemption or
otherwise), shall be and become part of the Collateral pledged by Westmark
hereunder and, if received by Westmark, shall be received in trust for the
benefit of MIOA or its assigns and shall forthwith be delivered to the Escrow
Agent (accompanied by proper instruments of assignment and/or stock and/or bond
powers executed by Westmark in accordance with MIOA's instructions) to be held
as Collateral subject to the terms of this Security Agreement.

                  (c) MIOA shall execute and deliver (or cause to be executed
and delivered) to Westmark all such proxies, powers of attorney, dividend
orders, interest

                                       2
<PAGE>

coupons and other instruments as Westmark may request for the purpose of
enabling Westmark to exercise the voting and/or consensual rights and powers
which it is entitled to exercise pursuant to subparagraph (a) above and/or to
receive the dividends and/or interest payments which it is authorized to receive
and retain pursuant to subparagraph (b) above.

                  (d) Upon the occurrence and during the continuance of an Event
of Default, all rights of Westmark to exercise the voting and/or consensual
rights and powers which it is entitled to exercise pursuant to Section 4(a)
hereof and/or to receive the dividends and interest payments which it is
authorized to receive and retain pursuant to Section 4(b) hereof shall cease,
and all such rights shall thereupon become vested in MIOA who shall have the
sole and exclusive right and authority to exercise such voting and/or consensual
rights and powers and/or to receive and retain the dividends and/or interest
payments which Westmark would otherwise be authorized to retain pursuant to
Section 4(b) hereof. Any and all money and other property paid over to or
received by MIOA pursuant to the provisions of this paragraph (d) or pursuant to
the exercise by MIOA of the voting and/or consensual rights and powers shall be
retained by MIOA as additional collateral hereunder and be applied in accordance
with the provisions of this Security Agreement.

                  (e) Prior to an Event of Default, MIOA shall not assert any
rights whatsoever with respect to the Collateral nor shall Westmark take any
action which would impair such rights.

         5. Each of the following shall be an event of default (an "Event of
Default") hereunder:

                           (a) If Westmark fails to pay when due the Potential
Debt to MIOA pursuant to Paragraph 9 of the Exchange Agreement;

                           (b) If Westmark shall default in the performance of
any term or provision of this Security Agreement or Paragraphs 2, 3, 6, 8, or 9
of the Exchange Agreement;

                           (c) If Westmark shall sell, transfer or encumber, or
attempt to sell, transfer or encumber the Collateral or any interest therein,
without the prior written consent of MIOA;

                           (d) Filing by or against Westmark of a petition in
bankruptcy or for reorganization or similar arrangement under the Bankruptcy
Code;

                           (e) Making a general assignment by Westmark for the
benefit of creditors; the appointment of a receiver or trustee for Westmark or
for any substantial

                                       3
<PAGE>

portion of its assets; or the institution by or against Westmark of any kind of 
insolvency proceedings or any proceeding for the dissolution or liquidation of 
Westmark;

                           (f) Material falsity in any certificate, statement,
representation, warranty, or audit at any time furnished to MIOA by or on behalf
of Westmark or any indorser or guarantor or any other party liable for payment
of any indebtedness in, pursuant to, or in connection with this Agreement or
otherwise and including any omission to disclose any substantial contingent or
liquidated liabilities or any material adverse change in any facts disclosed by
any certificate, statement, representation, warranty or audit furnished to MIOA.

                           (g) Condemnation or seizure of any of the Collateral.

                           (h) Failure by Westmark to be a corporation in good
standing with the State of Florida, if formed under the laws of Florida, or if
formed under the laws of another jurisdiction, failure to be in good standing
with such jurisdiction, and to have filed all reports and other documents
required by the State of Florida or such other jurisdiction in order to preserve
its status as a corporation in good standing, provided that Westmark shall have
thirty (30) days to cure any occurrence of this Event of Default upon written
notice from MIOA of the occurrence of same;

                           (i) If Westmark ceases doing business as a going
concern or commences the liquidation of its business or assets.

         6. Upon the occurrence of any Event of Default, MIOA may exercise all
the rights of a secured party under the Uniform Commercial Code of the State of
Florida and/or any other applicable law with respect to the Collateral. If the
proceeds of any sale or other lawful disposition by MIOA of the Collateral
subsequent to its retaking exceed the aggregate amount of the outstanding
balance of all monies owed pursuant to the Potential Debt and the expenses of
MIOA, including reasonable attorney's fees, in connection with the retaking and
disposition of the Collateral, then Westmark shall be entitled to such surplus.
If all or any of the Collateral is disposed of by private sale pursuant to any
agreement whereby all or part of the sale price is payable in installments, then
the cash price (exclusive of credit service charges, interest and any insurance
premiums) shall be credited against the indebtedness secured thereby. Neither
failure nor delay on the part of MIOA to exercise any of its rights hereunder,
in whole or in part, shall cause a waiver thereof in that or any other instance.
The provisions of this Agreement are cumulative and in addition to any other or
additional rights MIOA may have at law or in equity or under the terms of the
Exchange Agreement, or any other document collateral thereto.

                                       4
<PAGE>

         7. Westmark shall execute, deliver, file and refile any financing
statements, continuation statements, or other security agreements MIOA may
require from time to time to confirm the lien of this Agreement with respect to
the Collateral. Without limiting the foregoing, Westmark hereby irrevocably
appoints MIOA attorney-in-fact for Westmark to execute, deliver and file such
instruments for and on behalf of Westmark.

         8. (a) Greenberg Traurig shall initially act as Escrow Agent under this
Agreement. The Escrow Agent shall acknowledge its receipt of the original
certificate(s) representing the Collateral by executing this Agreement. Westmark
shall also deliver to the Escrow Agent any and all original certificates, funds
or documents as may hereafter become part of the Collateral. The possession of
the original certificates and other documents relating to the Collateral shall
be deemed to constitute MIOA's possession thereof in order to perfect MIOA's
security interest in the Collateral.

                           (b) The Escrow Agent shall hold all certificates,
funds and documents representing the Collateral (collectively, the
"Instruments") subject to the following terms and conditions:

                           (i) If MIOA at any time instructs the Escrow Agent to
exchange any certificates representing any securities included in the Collateral
to change the denominations of such certificates, the Escrow Agent shall comply
with such request promptly by so exchanging certificates directly with MIOA. The
Escrow Agent shall give Westmark and the holder of any subsequent perfected lien
as provided in the addendum to this Security Agreement notice of any such action
within 10 days after it is completed.

                           (ii) Either Westmark or MIOA may give the Escrow
Agent a notice requesting the Escrow Agent to make any delivery or take any
action with respect to any Instruments that is proposed to be taken pursuant to
this Agreement. If the notice describing any such request is executed by both
Westmark and MIOA, the Escrow Agent shall promptly comply with the request.

         If the notice is given by Westmark or MIOA, and is not signed by both,
the Escrow Agent shall promptly forward by hand or overnight delivery a copy of
such notice to the party that did not sign it. Thereafter, the Escrow Agent
shall refrain from taking any action with respect to such request for at least 5
business days, or until the other party authorizes the Escrow Agent in writing
to comply with such request. If the other party fails to deliver written notice
of objection to the Escrow Agent within such 5 day period, the Escrow Agent
shall be fully protected in complying with such request.

                           (c) In order to induce the Escrow Agent to act under
this Agreement, Westmark and MIOA jointly and severally agree as follows:

                           (i) The Escrow Agent shall not in any way be bound or
affected by any notice or modification or cancellation of this Agreement unless
in writing, signed by all parties hereto, nor shall the Escrow Agent be bound by
any modification hereof unless the same shall be satisfactory to the Escrow
Agent. The Escrow Agent shall be entitled to rely upon any judgment,
certification, demand or other writing (including but not limited to any
instructions given to it under (b), above) without being required to determine
the authenticity or the correctness of any fact stated therein, the propriety of
validity of the service thereof, or the jurisdiction of the court issuing such
judgment or order.

                           (ii) The Escrow Agent may act in reliance upon any
document, instrument or signature believed by it to be genuine, and the Escrow
Agent may assume that any person purporting to give any notice or instructions
in accordance with the provisions hereof has been duly authorized to do so.

                           (iii) The Escrow Agent may act relative hereto in
reliance upon advice of counsel in reference to any matter(s) in connection
herewith, and shall not be liable for any mistake of fact or error of judgment,
or for any acts or omissions of any kind, unless caused by the Escrow Agent's
willful misconduct or gross negligence. The Escrow Agent shall be entitled to
consult with its counsel, which shall include any attorney employed by it, and
the Escrow Agent shall not be liable for any action taken, suffered or omitted
by it in accordance with the advice (whether written or oral) of such counsel.

                           (iv) This Agreement sets forth exclusively the Escrow
Agent's duties with respect to any and all matters pertinent hereto. The Escrow
Agent shall not refer to, and shall not be bound by, the provisions of any other
agreement.

                           (v) The Escrow Agent may at any time resign hereunder
by giving written notice of its resignation to all parties hereto at least
thirty (30) days prior to the date specified for such resignation to take
effect, and upon the effective date of such resignation, all cash, documents and
all other property then held by the Escrow Agent hereunder shall be delivered by
it to such persons as may be designated in writing by all parties hereto,
whereupon all its prospective obligations as Escrow Agent hereunder shall cease
and terminate. The Escrow Agent's sole responsibility thereafter shall be to
keep safely all property then held by it and to deliver same to a person
designated by all parties hereto or in accordance with the directions of a final
order or judgment of a court of competent jurisdiction. In addition, the Escrow
Agent shall be


                                       6

discharged of its prospective duties and obligations hereunder upon its
interpleading in a court of competent jurisdiction all of the funds and property
then held by it hereunder. All parties hereto hereby submit to the personal
jurisdiction of said court (but solely for the purpose of implementing this
Agreement) and waive all rights to contest said jurisdiction. However, the
Escrow Agent's resignation and/or interpleading of the Collateral shall not in
any manner affect or impair any of its obligations under this Agreement.

                           (vi) Westmark shall be individually obligated to
reimburse the Escrow Agent for all its fees, costs and expenses in connection
herewith, including reasonable counsel fees. Westmark and MIOA shall be jointly
and severally obligated to indemnify the Escrow Agent and hold it harmless
against any claim asserted against it or any liability, loss or damage incurred
by it in connection herewith, including attorney's fees and costs.

                           (vii) Nothing herein contained shall be deemed to
obligate the Escrow Agent to deliver any securities, cash, instruments,
documents or any other property referred to herein, unless the same shall have
first been received by the Escrow Agent pursuant to this Agreement.

                           (viii) MIOA acknowledges that the Escrow Agent is
counsel for Westmark and agrees that no action taken by the Escrow Agent under
this Agreement shall affect or impair the right of the Escrow Agent to represent
such party(ies) in any matter, including an interpleader action pursuant to this
Agreement.

         9. This Agreement shall be binding upon and shall inure to the benefit
of the parties hereto, their respective successors and assigns.

         10. This Agreement shall be governed by and construed in accordance
with the laws of the State of Florida. Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid or unenforceable under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity without invalidating
the remainder of such provision or the remaining provisions of this Agreement.
