confirms its agreement with First Allied Securities, Inc. ("First Allied") and
each of the underwriters named in Schedule A hereto (collectively, the

hereinafter provided in Section 11), for whom First Allied is acting as
                        -------                                        
representative (in such capacity, First Allied shall hereinafter be referred to
as "you" or the "Representative"), with respect to the sale by the Company and
the purchase by the Underwriters, acting severally and not jointly, of the
respective numbers of shares of the Company's Series A ___% Cumulative
Convertible preferred stock, $.01 par value per share ("Preferred Stock") and

The shares of Preferred Stock and Redeemable Warrants will be separately

          Upon your request, as provided in Section 2(b) of this Agreement, the
                                            -------

additional 140,000 shares of Preferred Stock or ____ shares of common stock,
$.15 par value per share of the Company ("Common Stock") or any combination

          1.   Representations and Warranties of the Company.  The Company
               ---------------------------------------------              
represents and warrants to, and agrees with, each of the Underwriters as of the
date hereof, and as of the Closing Date (hereinafter defined) and the Option
Closing Date (hereinafter defined), if any, as follows:

               (a) The Company has prepared and filed with the Securities and
Exchange Commission (the "Commission") a registration statement, and an
amendment or amendments thereto, on Form S-1 (No. 333-02727), including any
related preliminary prospectus ("Preliminary Prospectus"), for the registration
of the Firm Securities and the Option Securities under the Securities Act of
1933, as amended (the "Act"), which registration statement and amendment or
amendments have been prepared by the Company in conformity with the requirements
of the Act, and the rules and regulations (the "Regulations") of the Commission
under the Act.  The Company will promptly file a further amendment to said
registration

                                     - 2 -
<PAGE>
 
statement in the form heretofore delivered to the Underwriters and will not,
file any other amendment thereto to which the Underwriters shall have objected
in writing after having been furnished with a copy thereof.  Except as the
context may otherwise require, such registration statement, as amended, on file
with the Commission at the time the registration statement becomes effective
(including the prospectus, financial statements, schedules, exhibits and all
other documents filed as a part thereof or incorporated therein (including, but
not limited to those documents or information incorporated by reference therein)
and all information deemed to be a part thereof as of such time pursuant to
paragraph (b) of Rule 430(A) of the Regulations)), is hereinafter called the
"Registration Statement", and the form of prospectus in the form first filed
with the Commission pursuant to Rule 424(b) of the Regulations, is hereinafter
called the "Prospectus."  For purposes hereof, "Rules and Regulations" mean the
rules and regulations adopted by the Commission under either the Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), as applicable.

               (b) Neither the Commission nor any state regulatory authority has
issued any order preventing or suspending the use of any Preliminary Prospectus,
the Registration Statement or Prospectus or any part of any thereof and no
proceedings for a stop order suspending the effectiveness of the Registration
Statement or any of the Company's securities have been instituted or are pending
or to the Company's knowledge, threatened.  Each of the Preliminary Prospectus,
the Registration Statement and Prospectus at the time of filing thereof
conformed with the requirements of the Act and the Rules and Regulations, and
none of the Preliminary Prospectus, the Registration Statement or Prospectus at
the time of filing thereof contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein and necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, except that this representation and warranty does not
apply to statements made in reliance upon and in conformity with written
information furnished to the Company with respect to the Underwriters by or on
behalf of the Underwriters expressly for use in such Preliminary Prospectus,
Registration Statement or Prospectus.

               (c) When the Registration Statement becomes effective and at all
times subsequent thereto up to the Closing Date and each Option Closing Date, if
any, and during such longer period as the Prospectus may be required to be
delivered in connection with sales by the Underwriters or a dealer, the
Registration Statement and the Prospectus will contain all statements which are
required to be stated therein in accordance with the Act and the Rules and
Regulations, and will conform to the requirements of the Act and the Rules and
Regulations; neither the Registration Statement nor the Prospectus, nor any
amendment or supplement thereto, will contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, provided, however, that this
                                      --------  -------  
representation and warranty does not apply to statements made or statements
omitted in reliance upon and in conformity with information furnished to the
Company in writing with respect to the Underwriters by or on behalf of any
Underwriter expressly for use in the Preliminary Prospectus, Registration
Statement or Prospectus or any amendment thereof or supplement thereto.

               (d) Each of the Company and its subsidiary, ICP Corporation, a
Utah corporation (the "Subsidiary") has been duly organized and is validly
existing as a corporation in good standing under the laws of the state of its
incorporation. Except as disclosed in the Prospectus, neither the Company nor
the Subsidiary owns an interest in any corporation, partnership, trust, joint
venture or other business entity. Each of the Company and the Subsidiary is duly
qualified and licensed and in good standing as a foreign corporation in each
jurisdiction in which its ownership or leasing of any properties or the
character of its operations requires such qualification or licensing. Each of
the Company and the Subsidiary has all requisite corporate power and authority,
and each has obtained any and all necessary authorizations, approvals, orders,
licenses, certificates, franchises and permits of and from all governmental or
regulatory officials and bodies (including, without limitation, those having
jurisdiction over environmental or similar matters), to own or lease its
properties and conduct its business as described in the Prospectus; each of the
Company and the Subsidiary is and has been doing business in compliance with all
such authorizations, approvals, orders, licenses, certificates, franchises and
permits and all federal, state and local laws, rules and regulations; and
neither received any notice of proceedings relating to the revocation or
modification of any such authorization, approval, order, license, certificate,
franchise, or permit which, singly or in the aggregate, if the subject of an
unfavorable decision, ruling or finding, would materially and adversely affect
the condition, financial or otherwise, or the earnings, position, prospects,
value, operation, properties, business or results of operations of the Company
or the Subsidiary. The disclosures in the Registration Statement concerning the
effects of federal, state and local laws, rules and regulations on each of the
Company's and the Subsidiary's business as currently conducted and as
contemplated are correct in all material respects and do not omit to state a
material fact necessary to make the statements contained therein not misleading
in light of the circumstances in which they were made.

               (e) The Company has a duly authorized, issued and outstanding
capitalization as set forth in the Prospectus, under "Capitalization" and
"Description of Securities" and will have the adjusted capitalization set forth
therein on the Closing Date and the Option Closing Date, if any, based upon the
assumptions set forth therein, and the Company is not a party to or bound by any
instrument, agreement or other arrangement providing for it to issue any capital
stock, rights, warrants, options or other securities, except for this Agreement,
the Representative's Warrant Agreement, the Warrant Agreement (as defined in
Section 1(ii)) and as described in the Prospectus.  The Securities and all other
securities issued or issuable by the Company conform or, when issued and paid
for, will conform, in all respects to all statements with respect thereto
contained in the Registration Statement and the Prospectus.  All issued and
outstanding securities of the Company and the Subsidiary have been duly
authorized and validly issued and are fully paid and non-assessable and the
holders thereof have no rights of rescission with respect thereto, and are not
subject to personal liability by reason of being such holders; and none of such
securities were issued in violation of the preemptive rights of any holders of
any security of the Company or the Subsidiary or similar contractual rights
granted by the Company or the Subsidiary.  The Securities are not and will not
be subject to any preemptive or other similar rights of any stockholder, have
been duly authorized and, when issued, paid for and delivered in accordance with
the terms hereof, will be validly issued, fully paid and non-assessable and will
conform to the description thereof contained in the Prospectus; the holders
thereof will not be subject to any liability solely as such holders; all
corporate action

                                     - 4 -
<PAGE>
 
required to be taken for the authorization, issue and sale of the Securities has
been duly and validly taken; and the certificates representing the Securities
will be in due and proper form.  Upon the issuance and delivery pursuant to the
terms hereof of the Securities to be sold by the Company hereunder, the
Underwriters or the Representative, as the case may be, will acquire good and
marketable title to such Securities free and clear of any lien, charge, claim,
encumbrance, pledge, security interest, defect or other restriction or equity of
any kind whatsoever.

               (f) The consolidated financial statements, including the related
notes and schedules thereto, included in the Registration Statement, each
Preliminary Prospectus and the Prospectus fairly present the financial position,
income, changes in cash flow, changes in stockholders' equity, and the results
of operations of the Company at the respective dates and for the respective
periods to which they apply and the pro forma financial information included in
the Registration Statement and Prospectus presents fairly on a basis consistent
with that of the audited financial statements included therein, what the

employment practices, terms and conditions of employment and wages and hours.
There are no pending investigations involving the Company by the U.S. Department
of Labor, or any other governmental agency responsible for the enforcement of

prohibited transactions and which has not adequately been corrected.  Each ERISA
Plan is in compliance with all reporting, disclosure and other requirements of

the Firm Securities upon notice by the Representative to the Company setting

seven full business days after the exercise of said option, nor in any event
prior to the Closing Date, as hereinafter defined, unless otherwise agreed upon
by the Representative and the Company.  Nothing herein contained shall obligate
the Underwriters to make any over-allotments.  No Option Securities shall be
delivered unless the Firm Securities shall be simultaneously delivered or shall
theretofore have been delivered as herein provided.

               (c) Payment of the purchase price for, and delivery of
certificates for, the Firm Securities shall be made at the offices of First

               -----------------------------                                 
Statement becomes effective as the Representative deems advisable, the
Underwriters shall make a public offering of the Preferred Stock and the
Redeemable Warrants (other than to residents of or in any jurisdiction in which
qualification of the Preferred Stock and the Redeemable Warrants is required and
has not become effective) at the price and upon the other terms set forth in the
Prospectus.  The Representative may from time to time increase or decrease the
public offering price after distribution of the Preferred Stock and the
Redeemable Warrants has been completed to such extent as the Representative, in
it discretion deems advisable.  The Underwriters may enter into one of more
agreements as the Underwriters, in each of their sole discretion, deem advisable
with one or more broker-dealers who shall act as dealers in connection with such
public offering.

          4.   Covenants and Agreements of the Company.  The Company covenants
               ---------------------------------------                        
and agrees with each of the Underwriters as follows:

               (a) The Company shall use its best efforts to cause the
Registration Statement and any amendments thereto to become effective as
promptly as practicable and will not at any time, whether before or after the
effective date of the Registration Statement, file any amendment to the
Registration Statement or supplement to the Prospectus or file any document
under the Act or Exchange Act before termination of the offering of the Shares
by the Underwriters of which the Representative shall not previously have been
advised and furnished with a copy, or to which the Representative shall have
objected or which is not in compliance with the Act, the Exchange Act or the
Rules and Regulations.

               (b) As soon as the Company is advised or obtains knowledge
thereof, the Company will advise the Representative and confirm the notice in
writing, (i) when the Registration Statement, as amended, becomes effective, if
the provisions of Rule 430A promulgated under the Act will be relied upon, when
the Prospectus has been filed in accordance with said Rule 430A and when any
post-effective amendment to the Registration Statement becomes effective, (ii)
of the issuance by the Commission of any stop order or of the initiation, or the
threatening, of any proceeding, suspending the effectiveness of the Registration
Statement or any order preventing or suspending the use of the Preliminary
Prospectus or the Prospectus, or any amendment or supplement thereto, or the
institution of proceedings for that purpose, (iii) of the issuance by the
Commission or by any state securities commission of any proceedings for the
suspension of the qualification of any of the Securities for offering or sale in
any jurisdiction or of the initiation, or the threatening, of any proceeding for
that purpose, (iv) of the receipt of

                                     - 14 -
<PAGE>
 
any comments from the Commission; and (v) of any request by the Commission for
any amendment to the Registration Statement or any amendment or supplement to
the Prospectus or for additional information.  If the Commission or any state
securities commission authority shall enter a stop order or suspend such
qualification at any time, the Company will make every effort to obtain promptly
the lifting of such order.

               (c) The Company shall file the Prospectus (in form and substance
satisfactory to the Representative) or transmit the Prospectus by a means
reasonably calculated to result in filing with the Commission pursuant to Rule
424(b)(1) (or, if applicable and if consented to by the Representative, pursuant
to Rule 424(b)(4)) not later than the Commission's close of business on the
earlier of (i) the second business day following the execution and delivery of
this Agreement and (ii) the fifteenth business day after the effective date of
the Registration Statement.

               (d) The Company will give the Representative notice of its
intention to file or prepare any amendment to the Registration Statement
(including any post-effective amendment) or any amendment or supplement to the
Prospectus (including any revised prospectus which the Company proposes for use
by the Underwriters in connection with the offering of the Securities which
differs from the corresponding prospectus on file at the Commission at the time
the Registration Statement becomes effective, whether or not such revised
prospectus is required to be filed pursuant to Rule 424(b) of the Rules and
Regulations), and will furnish the Representative with copies of any such
amendment or supplement a reasonable amount of time prior to such proposed
filing or use, as the case may be, and will not file any such prospectus to
which the Representative or Orrick, Herrington & Sutcliffe ("Underwriters'
Counsel"), shall object.

               (e) The Company shall endeavor in good faith, in cooperation with
the Representative, at or prior to the time the Registration Statement becomes
effective, to qualify the Securities for offering and sale under the securities
laws of such jurisdictions as the Representative may designate to permit the
continuance of sales and dealings therein for as long as may be necessary to
complete the distribution, and shall make such applications, file such documents
and furnish such information as may be required for such purpose; provided,
                                                                  -------- 
however, the Company shall not be required to qualify as a foreign corporation
- -------                                                                       
or file a general or limited consent to service of process in any such
jurisdiction.  In each jurisdiction where such qualification shall be effected,
the Company will, unless the Representative agrees that such action is not at
the time necessary or advisable, use all reasonable efforts to file and make
such statements or reports at such times as are or may reasonably be required by
the laws of such jurisdiction to continue such qualification.

               (f) During the time when a prospectus is required to be delivered
under the Act, the Company shall use all reasonable efforts to comply with all
requirements imposed upon it by the Act and the Exchange Act, as now and
hereafter amended and by the Rules and Regulations, as from time to time in
force, so far as necessary to permit the continuance of sales of or dealings in
the Securities in accordance with the provisions hereof and the Prospectus, or
any amendments or supplements thereto.  If at any time when a prospectus
relating to the Securities is required to be delivered under the Act, any event
shall have occurred as a result

                                     - 15 -
<PAGE>
 
of which, in the opinion of counsel for the Company or Underwriters' Counsel,
the Prospectus, as then amended or supplemented, includes an untrue statement of
a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, or if it is necessary
at any time to amend the Prospectus to comply with the Act, the Company will
notify the Representative promptly and prepare and file with the Commission an
appropriate amendment or supplement in accordance with Section 10 of the Act,
                                                       -------               
each such amendment or supplement to be satisfactory to Underwriters' Counsel,
and the Company will furnish to the Underwriters copies of such amendment or
supplement as soon as available and in such quantities as the Underwriters may
request.

               (g) As soon as practicable, but in any event not later than 45
days after the end of the 12-month period beginning on the day after the end of
the fiscal quarter of the Company during which the effective date of the
Registration Statement occurs (90 days in the event that the end of such fiscal
quarter is the end of the Company's fiscal year), the Company shall make
generally available to its security holders, in the manner specified in Rule
158(b) of the Rules and Regulations, and to the Representative, an earnings
statement which will be in the detail required by, and will otherwise comply
with, the provisions of Section 11(a) of the Act and Rule 158(a) of the Rules
                        -------                                              
and Regulations, which statement need not be audited unless required by the Act,
covering a period of at least 12 consecutive months after the effective date of
the Registration Statement.

               (h) During a period of seven years after the date hereof, the
Company will furnish to its stockholders, as soon as practicable, annual reports
(including financial statements audited by independent public accountants) and
unaudited quarterly reports of earnings, and will deliver to the Representative:

          stockholders, statements of income of the Company for each quarter in
          the form furnished to the Company's stockholders and certified by the
          Company's principal financial or accounting officer;

               ii) concurrently with furnishing such annual reports to its
          stockholders, a balance sheet of the Company as at the end of the
          preceding fiscal year, together with statements of operations,

          year, accompanied by a copy of the certificate thereon of independent
          certified public accountants;

               iii) as soon as they are available, copies of all reports
          (financial or other) mailed to stockholders;

               iv) as soon as they are available, copies of all reports and

          interest to the financial community in respect of the Company, or its
          affairs which was released or prepared by or on behalf of the Company;
          and

               vi) any additional information of a public nature concerning the
          Company (and any future subsidiary) or its businesses which the
          Representative may request.

          During such seven-year period, if the Company has an active
subsidiary, the foregoing financial statements will be on a consolidated basis
to the extent that the accounts of the Company and its subsidiary are
consolidated, and will be accompanied by similar financial statements for any
significant subsidiary which is not so consolidated.

               (i) The Company will maintain a Transfer Agent and Warrant Agent
and, if necessary under the jurisdiction of incorporation of the Company, a
Registrar (which may be the same entity as the Transfer Agent) for its Preferred
Stock, Common Stock and Redeemable Warrants.

               (j) The Company will furnish to the Representative or on the

otherwise) or dispose of any beneficial interest therein without the prior
written consent of the Representative (collectively, the "Lock-up Agreements").
On or before the Closing Date, the Company shall deliver instructions to the
Transfer Agent authorizing it to place appropriate legends on the certificates
representing the securities subject to the Lock-up Agreements and to place
appropriate stop transfer orders on the Company's ledgers. During the thirteen
(13) month period commencing with the effective date of the Registration

Prospectus, the Registration Statement and Prospectus, on the basis of the

to believe that either the Registration Statement or any amendment thereto, at

justified in relying thereon.

          of the Company (including a break-down of commercial paper and notes
          payable to banks);

               v) stating that they have compared specific dollar amounts,
          numbers of shares, percentages of revenues and earnings, statements
          and other financial information pertaining to the Company set forth in
          the Prospectus in each case to the extent that such amounts, numbers,
          percentages, statements and information may be derived from the
          general accounting records, including work sheets, of the Company and
          excluding any questions requiring an interpretation by legal counsel,
          with the results obtained from the application of specified readings,
          inquiries and other appropriate procedures (which procedures do not
          constitute an examination in accordance with generally accepted
          auditing standards) set forth in the letter and found them to be in
          agreement; and

               vi) statements as to such other matters incident to the
          transaction contemplated hereby as the Representative may request.

          (p) At the Closing Date and each Option Closing Date, if any, the
Underwriters shall have received from BDO a letter, dated as of the Closing Date
or the Option Closing Date, as the case may be, to the effect that they reaffirm
the statements made in the letter furnished pursuant to subsection (i) of this

more than five days prior to the Closing Date or the Option Closing Date, as the
case may be, and, if the Company has elected to rely on Rule 430A of the Rules
and Regulations, to the further effect that they have carried out procedures as
specified in clause (v) of subsection (i) of this Section with respect to
                           ----------             -------                
certain amounts, percentages and financial information as specified by the
Representative and deemed to be a part of the Registration Statement pursuant to
Rule 430A(b) and have found such amounts, percentages and financial information
to be in agreement with the records specified in such clause (v).

               (q) The Company shall have delivered to the Representative a

as the case may be, is not so fulfilled, the Representative may terminate this
Agreement or, if the Representative so elects, it may waive any such conditions
which have not been fulfilled or extend the time for their fulfillment.

          7.   Indemnification.
               --------------- 

               (a) The Company, agrees to indemnify and hold harmless each of
the Underwriters (for purposes of this Section 7 "Underwriter" shall include the
                                       -------                                  
officers, directors, partners, employees, agents and counsel of the Underwriter,
including specifically each person who may be substituted for an Underwriter as
provided in Section 11 hereof), and each person, if any, who controls the
            -------                                                      
Underwriter ("controlling person") within the meaning of Section 15 of the Act
                                                         -------              
or Section 20(a) of the Exchange Act, from and against any and all losses,
   -------                                                                
claims, damages, expenses or liabilities, joint or several (and actions,
proceedings, investigations, inquiries, and suits in respect thereof),
whatsoever (including but not limited to any and all costs and expenses
whatsoever reasonably incurred in investigating, preparing or defending against
such action, proceeding, investigation, inquiry or suit, commenced or
threatened, or any claim whatsoever), as such are incurred, to which the
Underwriter or such controlling person may become subject under the Act, the
Exchange Act or any other statute or at common law or otherwise or under the
laws of foreign countries, arising out of or based upon (A) any untrue 

                                     - 37 -
<PAGE>
 
statement or alleged untrue statement of a material fact contained (i) in any
Preliminary Prospectus, the Registration Statement or the Prospectus (as from
time to time amended and supplemented); (ii) in any post-effective amendment or
amendments or any new registration statement and prospectus in which is included
securities of the Company issued or issuable upon exercise of the Securities; or
(iii) in any application or other document or written communication (in this
Section 7 collectively called "application") executed by the Company or based 
- -------  
upon written information furnished by the Company filed, delivered or used in
any jurisdiction in order to qualify the Securities under the securities laws
thereof or filed with the Commission, any state securities commission or agency,
Nasdaq or any other securities exchange, (B) the omission or alleged omission
therefrom of a material fact required to be stated therein or necessary to make
the statements therein not misleading (in the case of the Prospectus, in the
light of the circumstances under which they were made), or (C) any breach of any
representation, warranty, covenant or agreement of the Company contained herein
or in any certificate by or on behalf of the Company or any of its officers
delivered pursuant hereto unless, in the case of clause (A) or (B) above, such
statement or omission was made in reliance upon and in conformity with written
information furnished to the Company with respect to any Underwriter by or on
behalf of such Underwriter expressly for use in any Preliminary Prospectus, the
Registration Statement or any Prospectus, or any amendment thereof or supplement
thereto, or in any application, as the case may be.

          The indemnity agreement in this subsection (a) shall be in addition to
any liability which the Company may have at common law or otherwise.

               (b) Each of the Underwriters agrees severally, but not jointly,
to indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the Registration Statement, and each other person, if
any, who controls the Company within the meaning of the Act, to the same extent
as the foregoing indemnity from the Company to the Underwriters but only with
respect to statements or omissions, if any, made in any Preliminary Prospectus,
the Registration Statement or Prospectus or any amendment thereof or supplement
thereto or in any application made in reliance upon, and in strict conformity
with, written information furnished to the Company with respect to any
Underwriter by such Underwriter expressly for use in such Preliminary
Prospectus, the Registration Statement or Prospectus or any amendment thereof or
supplement thereto or in any such application, provided that such written
information or omissions only pertain to disclosures in the Preliminary
Prospectus, the Registration Statement or Prospectus directly relating to the
transactions effected by the Underwriters in connection with this Offering. The
Company acknowledges that the statements with respect to the public offering of
the Securities set forth under the heading "Underwriting" and the stabilization
legend in the Prospectus have been furnished by the Underwriters expressly for
use therein and constitute the only information furnished in writing by or on
behalf of the Underwriters for inclusion in the Prospectus.

          The indemnity agreement in this subsection (b) shall be in addition to
any liability which the Underwriters may have at common law or otherwise.

               (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, suit or proceeding, such
- -------
indemnified party shall, if 

                                     - 38 -
<PAGE>
 
a claim in respect thereof is to be made against one or more indemnifying
parties under this Section 7, notify each party against whom indemnification is 
                   -------                             
to be sought in writing of the commencement thereof (but the failure so to
notify an indemnifying party shall not relieve it from any liability which it
may have under this Section 7 except to the extent that it has been prejudiced 
                    -------                               
in any material respect by such failure or from any liability which it may have
otherwise). In case any such action, investigation, inquiry, suit or proceeding
is brought against any indemnified party, and it notifies an indemnifying party
or parties of the commencement thereof, the indemnifying party or parties will
be entitled to participate therein, and to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party. Notwithstanding the
foregoing, the indemnified party or parties shall have the right to employ its
or their own counsel in any such case but the fees and expenses of such counsel
shall be at the expense of such indemnified party or parties unless (i) the
employment of such counsel shall have been authorized in writing by the
indemnifying parties in connection with the defense of such action at the
expense of the indemnifying party, (ii) the indemnifying parties shall not have
employed counsel reasonably satisfactory to such indemnified party to have
charge of the defense of such action within a reasonable time after notice of
commencement of the action, or (iii) such indemnified party or parties shall
have reasonably concluded that there may be defenses available to it or them
which are different from or additional to those available to one or all of the
indemnifying parties (in which case the indemnifying parties shall not have the
right to direct the defense of such action, investigation, inquiry, suit or
proceeding on behalf of the indemnified party or parties), in any of which
events such fees and expenses of one additional counsel shall be borne by the
indemnifying parties. In no event shall the indemnifying parties be liable for
fees and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action, investigation, inquiry, suit or proceeding or separate but
similar or related actions, investigations, inquiries, suits or proceedings in
the same jurisdiction arising out of the same general allegations or
circumstances. Anything in this Section 7 to the contrary notwithstanding, an 
                                -------
indemnifying party shall not be liable for any settlement of any claim or action
effected without its written consent; provided, however, that such consent was
                                      --------  -------
not unreasonably withheld. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle compromise or consent to the
entry of any judgment with respect to any pending or threatened claim, action,
investigation, inquiry, suit or proceeding in respect of which indemnification
or contribution may be sought hereunder (whether or not the indemnified parties
are actual or potential parties to such claim or action), unless such
settlement, compromise or consent (i) includes an unconditional release of each
indemnified party form all liability arising out of such claim, action, suit or
proceeding and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

               (d) In order to provide for just and equitable contribution in
any case in which (i) an indemnified party makes claim for indemnification
pursuant to this Section 7, but it is judicially determined (by the entry of a
                 -------  
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
the express provisions of this Section 7 provide for indemnification in such
                               -------                                      
case, or (ii) contribution under 

                                     - 39 -
<PAGE>
 
the Act may be required on the part of any indemnified party, then each
indemnifying party shall contribute to the amount paid as a result of such
losses, claims, damages, expenses or liabilities (or actions, investigations,
inquiries, suits or proceedings in respect thereof) (A) in such proportion as is
appropriate to reflect the relative benefits received by each of the
contributing parties, on the one hand, and the party to be indemnified on the
other hand, from the offering of the Securities or (B) if the allocation
provided by clause (A) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of each of the contributing
parties, on the one hand, and the party to be indemnified on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages, expenses or liabilities, as well as any other relevant
equitable considerations. In any case where the Company is the contributing
party and the Underwriters are the indemnified party, the relative benefits
received by the Company on the one hand, and the Underwriters, on the other,
shall be deemed to be in the same proportion as the total net proceeds from the
offering of the Securities (before deducting expenses) bear to the total
underwriting discounts received by the Underwriters hereunder, in each case as
set forth in the table on the Cover Page of the Prospectus. Relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, or by the
Underwriters, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, expenses or liabilities (or actions, investigations, inquiries,
suits or proceedings in respect thereof) referred to above in this subdivision
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action, claim, investigation, inquiry, suit or proceeding. Notwithstanding the
provisions of this subdivision (d) the Underwriters shall not be required to
contribute any amount in excess of the underwriting discount applicable to the
Securities purchased by the Underwriters hereunder. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
                                                    -------         
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 7, each person,
                                                   -------                
if any, who controls the Company within the meaning of the Act, each officer of
the Company who has signed the Registration Statement, and each director of the
Company shall have the same rights to contribution as the Company, subject in
each case to this subparagraph (d).  Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action, suit, inquiry,
investigation or proceeding against such party in respect to which a claim for
contribution may be made against another party or parties under this
subparagraph (d), notify such party or parties from whom contribution may be
sought, but the omission so to notify such party or parties shall not relieve
the party or parties from whom contribution may be sought from any obligation it
or they may have hereunder or otherwise than under this subparagraph (d), or to
the extent that such party or parties were not adversely affected by such
omission.  The contribution agreement set forth above shall be in addition to
any liabilities which any indemnifying party may have at common law or
otherwise.

          8.   Representations and Agreements to Survive Delivery.  All
               --------------------------------------------------

case may be.

Agreement shall at all times be effective.  For purposes of this Section 9, the
                                                                 -------

published relating to the Securities.

          10.  Termination.

crisis or there shall have been such a material adverse change in the conditions
or prospects of the Company, or such material adverse change in the general

                                     - 41 -
<PAGE>
 
it inadvisable to proceed with the offering, sale and/or delivery of the

Underwriters shall fail (otherwise than for a reason sufficient to justify the
termination of this Agreement under the provisions of Section 6, Section 10 or
                                                      -------    -------      
Section 12 hereof) to purchase the Securities which it or they are obligated to

purchase on such date under this Agreement (the "Defaulted Securities"), the
Representative shall have the right, within 24 hours thereafter, to make
arrangement for one or more of the non-defaulting Underwriters, or any other

          total number of Firm Securities, this Agreement shall terminate
          without liability on the part of any non-defaulting Underwriters.

          No action taken pursuant to this Section shall relieve any defaulting
                                           -------                             
Underwriter from liability in respect of any default by such Underwriter under
this Agreement.

          In the event of any such default which does not result in a

                           CERTIFICATE OF AMENDMENT

                                      OF

                           ARTICLES OF INCORPORATION

                                      OF

                       MEDICAL DEVICE TECHNOLOGIES, INC.

To the Division of Corporations and
  Commercial Code of the State of Utah:

     Pursuant to the Provisions of Section 16-10a-602(4) of the Utah Business
Corporation Act, Medical Device Technologies, Inc. (the "Corporation") submits
the following amendment to its Articles of Incorporation.

     FIRST:  The Articles of Incorporation of the Corporation are amended to add
the following to Article IV thereof:

     The rights, preferences and designations of the authorized and unissued
shares of the Corporation's preferred stock shall hereafter be as follows:

     SECTION 1.  Designation.  _____________________________(________) shares
of preferred stock are hereby designated as __% Cumulative Convertible Series A
Preferred Stock ("Preferred Stock").  The rights, preferences, privileges and
qualifications, limitations and restrictions of the Preferred Stock are set
forth in Sections 2 through 6 of this certificate of amendment (this
"Certificate").  The rights, preferences, privileges and qualifications,
limitations and restrictions of the remaining shares of Preferred Stock shall be
determined by the Corporation's board of directors (the "Board of Directors"),
from time to time after the date of this Certificate, pursuant to the provisions
of Article IV of the Corporation's Articles of Incorporation.

     SECTION 2.  Dividends.  The holders of the Preferred Stock are entitled to
receive if, when and as declared by the Board of Directors out of funds legally
available therefor, cumulative dividends, payable solely in common stock of the
Corporation, par value $.15 per share (the "Common Stock") at the rate of __%
per annum of the liquidation value of the Preferred Stock (the "Liquidation
Value").  The Liquidation Value shall be equal to $5.00.  The dividend is
payable semi-annually on June 30 and December 31 of each year, commencing June
30, 1996. Dividends shall be paid to the holders of record as of a date, not
more than thirty (30) days prior to the dividend payment date, as may be fixed
by the Board of Directors (the "Dividend Declaration Date").  Dividends accrue
from the first day of the semi-annual period in which such dividend may be
payable, except with respect to the first semi-annual dividend which shall
accrue
<PAGE>
 
from the date of issuance of the Preferred Stock.  Each holder of Preferred
Stock shall receive shares of Common Stock equal to the quotient of (i) __% of
the Liquidation Value of the Preferred Stock divided by (ii) the average ten
(10) day moving average closing bid price of the Common Stock during the thirty
(30) trading days immediately prior to the Dividend Declaration Date (the "Stock
Dividend Price"); provided, however, that in no event shall the Stock Dividend
                  --------  -------                                           
Price ever exceed $1.50 per share or be less than $.70 per share.

     No dividends may be paid on any shares of capital stock ranking junior to
the Preferred Stock unless and until all declared but unpaid dividends on the
Preferred Stock have been declared and paid in full.

     SECTION 3.  Conversion.  The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

               (a)  Right to Convert.  Each outstanding share of Preferred 
                    ----------------
Stock will be convertible, at the option of the holder, at any time commencing
on ___________, 1996 (the "Conversion Date"). Each share of Preferred Stock is
convertible into _____________ (__) shares of Common Stock. The conversion price
of the Common Stock issuable upon conversion of the Preferred Stock shall be
equal to $____ per share of Common Stock (the "Conversion Price"), subject to
adjustment pursuant to paragraphs (d) and (e) of this Section 3. All accrued but
unpaid Common Stock dividends shall be paid upon conversion.

               (b)  Automatic Conversion.  Unless earlier converted, all the
                    --------------------
outstanding shares of Preferred Stock will be automatically converted into
Common Stock without any action by the holders thereof on ________, 1997 (the
"Automatic Conversion Date").

               (c)  Mechanics of Conversion.  Any holder of Preferred Stock who
                    -----------------------
wishes to convert the same into shares of Common Stock pursuant to paragraph (a)
of this Section 3, must surrender the certificate therefor, at the office of the
Corporation or of any transfer agent for such stock, and give written notice to
the Corporation at such office that he elects to convert the same. Such notice
shall not be required if the conversion is automatic under paragraph (b) of this
Section 3. The Corporation shall, as soon as practicable thereafter, issue to
such holder of Preferred Stock, a certificate for the number of shares of Common
Stock to which he shall be entitled as aforesaid. Such conversion shall be
deemed to have been made upon the surrender of the certificate for the shares of
Preferred Stock to be converted, and the person entitled to receive the shares
of Common Stock issuable upon such conversion shall be

                                       2
<PAGE>
 
treated for all purposes as the record holder of such shares of Common Stock at
and after such time.

               (d)  Adjustments to Conversion Price for Stock Dividends and for
                    -----------------------------------------------------------
Combinations or Subdivisions of Common Stock. If the Corporation at any time or
- --------------------------------------------                                   
from time to time while shares of Preferred Stock are issued and outstanding
shall declare or pay, without consideration, any dividend on the Common Stock
payable in Common Stock, or shall effect a subdivision of the outstanding shares
of Common Stock into a greater number of shares of Common Stock (by stock split,
reclassification or otherwise than by payment of a dividend in Common Stock or
in any right to acquire Common Stock), or if the outstanding shares of Common
Stock shall be combined or consolidated, by reclassification or otherwise, into
a lesser number of shares of Common Stock, then the Conversion Price for
Preferred Stock in effect immediately before such event shall, concurrently with
the effectiveness of such event, be proportionately decreased or increased, as
appropriate.  If the Corporation shall declare or pay, without consideration,
any dividend on the Common Stock payable in any right to acquire Common Stock
for no consideration, then the Corporation shall be deemed to have made a
dividend payable in Common Stock in an amount of shares equal to the maximum
number of shares issuable upon exercise of such rights to acquire Common Stock.

               (e)  Adjustments for Reclassification and Reorganization.  If the
                    ---------------------------------------------------
Common Stock issuable upon conversion of the Preferred Stock shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision or combination of shares provided for in paragraph (d) of
this Section 3), the Conversion Price then in effect shall, concurrently with
the effectiveness of such reorganization or reclassification, be proportionately
adjusted so that the Preferred Stock shall be convertible into, in lieu of the
number of shares of Common Stock which the holders would otherwise have been
entitled to receive, a number of shares of such other class or classes of stock
equivalent to the number of shares of Common Stock that would have been subject
to receipt by the holders upon conversion of the Preferred Stock immediately
before that change.

               (f)  No Impairment.  The Corporation will not, by amendment of 
                    -------------
its Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issuance or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all of the provisions of
this Section 3 and in the taking of all such action as may be

                                       3
<PAGE>
 
necessary or appropriate in order to protect the Conversion Rights of the
holders of the Preferred Stock against impairment. The provisions of this
paragraph (f) may be waived by the affirmative vote of the holders of at least a
majority of the then outstanding shares of Preferred Stock voting together as a
single class and taken in advance of any action that would conflict with this
paragraph (f).

               (g)  Notice of Adjustments.  Upon the occurrence of each 
                    --------------------- 
adjustment or readjustment of any Conversion Price pursuant to this Section 3,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a notice setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based.

               (h)  Notices of Record Date.  If the Corporation shall propose 
                    ----------------------
at any time: (i) to declare any dividend or distribution upon its Common Stock,
whether in cash, property, stock or other securities, other than a regular cash
dividend out of earnings or earned surplus or a dividend as to which adjustment
of the Conversion Price will be made under paragraph (d) of this Section 3; (ii)
to offer for subscription pro rata to the holders of any class or series of its
stock any additional shares of stock of any class or series or other rights;
(iii) to effect any reclassification or recapitalization of its Common Stock
outstanding involving a change in the Common Stock other than one as to which
adjustments of the Conversion Price will be made under paragraph (d) of this
Section 3; or (iv) to merge or consolidate with or into any other corporation,
or sell all or substantially all of its assets, or to liquidate, dissolve or
wind up; then, in connection with such event, the Corporation shall send to the
holders of the Preferred Stock;

               (1)  at least ten (10) days' prior written notice of the date on
                    which a record shall be taken for such dividend,
                    distribution or subscription rights (and specifying the date
                    on which the holders of Common Stock shall be entitled
                    thereto) or for determining rights to vote, if any, in
                    respect of the matters referred to in clauses (iii) and (iv)
                    above; and

               (2)  in the case of the matters referred to in clauses (iii) and
                    (iv) above, at least ten (10) days' prior written notice of
                    the date when the same shall take place (and specifying the
                    date on which the holders of Common Stock shall be entitled
                    to exchange their Common Stock for securities or other

                                       4
<PAGE>
 
                    property deliverable upon the occurrence of such event).

          (i)  Issue Taxes.  The Corporation shall pay any and all issue and
               -----------                                                  
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of Preferred Stock pursuant hereto; provided,
                                                               -------- 
however, that the Corporation shall not be obligated to pay any transfer taxes
- -------                                                                       
resulting from any transfer requested by any holder in connection with any such
conversion.

          (j)  Reservation of Stock Issuable Upon Conversion. The Corporation
               ---------------------------------------------                 
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Preferred Stock, the
Corporation will take such corporate action as may be necessary to increase its
authorized but unissued shares of Common Stock to such number of shares as shall
be sufficient for such purpose, including, without limitation, engaging in best
efforts to obtain the requisite stockholder approval of any necessary amendment
to its Articles of Incorporation.

          (k)  Fractional Shares.  No fractional share shall be issued upon the
               -----------------                                               
conversion of any share or shares of Preferred Stock.  All shares of Common
Stock (including fractions thereof) issuable upon conversion of more than one
share of Preferred Stock by a holder thereof shall be aggregated for purposes of
determining whether the conversion would result in the issuance of any
fractional share.  If, after the aforementioned aggregation, the conversion
would result in the issuance of a fractional share of Common Stock, such
fractional share shall be rounded up to the nearest whole share.

          (l)  Notices.  Any notice required by the provisions of this Section 3
               -------                                                          
to be given to the holders of shares of Preferred Stock shall be deemed given if
deposited in the United States mail, postage prepaid, and addressed to each
holder of record at his address appearing on the books of the Corporation.

     SECTION 4.  Voting Rights.  Each holder of shares of Preferred Stock will
be entitled to the number of votes equal to the number of shares of Common Stock
into which such holder's shares of Preferred Stock could be converted at the
time of the vote, will have voting rights equal to the voting rights of such
number of shares of Common Stock voting together with the Common Stock as a
single class on all matters submitted to the holders

                                       5
<PAGE>
 
of Common Stock and shall be entitled to notice of any stockholders' meeting.
Any fractional voting rights resulting from the above formula (after aggregating
all shares of Common Stock into which shares of Preferred Stock held by a single
holder are converted) will be disregarded.

     SECTION 5.  Liquidation Preference.  The holders of shares of Preferred
Stock will be entitled to receive, in the event of any liquidation, dissolution
or winding up of the Corporation, whether voluntary or involuntary, out of or to
the extent of the net assets of the Corporation legally available for such
distribution, before any distributions are made with respect to any Common Stock
or any stock ranking junior to the Preferred Stock, $_____ per share, plus any
declared but unpaid dividends (the "Liquidation Preference").  After payment of
the full amount of the Liquidation Preference, the holders of shares of
Preferred Stock will not be entitled to any further participation in any
distribution of assets by the Corporation.

     Upon any such liquidation, dissolution or winding up, such preferential
amounts with respect to the Preferred Stock and any class or series ranking on a
parity with the Preferred Stock if not paid in full shall be distributed pro
rata in accordance with the aggregate preferential amounts of the Preferred
Stock and such other classes or series of stock, if any.  So long as any shares
of Preferred Stock are issued and outstanding, the Corporation shall not issue
any securities with rights, preferences or provisions senior to the Preferred
Stock.

     SECTION 6.     Restrictions and Limitations.

               (a)  Shares of Preferred Stock acquired by the Corporation by
reason of purchase, conversion, redemption or otherwise shall be retired and
shall become authorized but unissued shares of Preferred Stock, which may be
reissued as part of a new series of Preferred Stock hereafter created under
Article IV of the Corporation's Articles of Incorporation.

               (b)  So long as shares of Preferred Stock remain outstanding, the
Corporation shall not, without the affirmative vote of the holders of at least a
majority of the then outstanding shares of Preferred Stock voting together as a
separate class, amend the terms of this Certificate.  The holders of the
outstanding shares of the Preferred Stock shall be entitled to vote as a
separate class upon a proposed amendment of the Articles of Incorporation if the
amendment would alter or change the powers, preferences or special rights of the
shares of Preferred Stock so as to affect them adversely.

     SECOND:   The Board of Directors of the Company duly adopted a resolution
at a meeting duly convened on ___________, 1996 at which a quorum was present
and acting throughout to amend the

hereof) per Preferred Share and/or Common Share and/or Redeemable Warrant set
forth in Section 6 hereof payable by certified or official bank check in New
         -------

                                                                -------  
hereof.  Upon surrender of a Warrant Certificate with the annexed Form of

thereunder, the Holder(s) of the Warrants shall have the right at any time and
from time to time to exercise the Warrants in full or in part by surrendering
the Warrant Certificate in the manner specified in Section 3.1 in exchange for
                                                   -------

Price" at any date shall be deemed to be the last reported sale price, or, in
case no such reported sale takes place on such day, the average of the last
reported sale prices for the last three (3) trading days, in either case as
officially reported by the principal securities exchange on which the Preferred
Stock or Common Stock, as the case may be, is listed or admitted to trading or
by the Nasdaq SmallCap Market ("NSM") or Nasdaq National Market ("NNM") as the
case may be, or, if the Preferred Stock or Common Stock, as the case may be, is
not listed or admitted to trading on any national securities exchanged or quoted
by NSM or NNM, the average closing bid price as furnished by the NASD through
NSM or NNM or similar organization if NSM or

NNM is no longer reporting such information, or if the Preferred Stock or Common
Stock, as the case may be, is not quoted on NSM or NNM, as determined in good
faith by resolution of the Board of Directors of the Company, based on the best
information available to it.

          (S)7.1 Registration Under the Securities Act of 1933.  The Warrants,
                 ---------------------------------------------                
the Principal Securities, and any of the other securities issuable upon exercise
of the Warrants have not been registered under the Securities Act of 1933, as
amended (the "Act").  Upon exercise, in part or

                                       7
<PAGE>
 
in whole, of the Warrants, certificates representing the Principal Securities
underlying the Warrants, and any of the other securities issuable upon exercise
of the Warrants (collectively, the "Warrant Securities") shall bear the
following legend:

          The securities represented by this certificate have not been
          registered under the Securities Act of 1933, as amended
          ("Act"), and may not be offered or sold except pursuant to
          (i) an effective registration statement under the Act, (ii)
          to the extent applicable, Rule 144 under the Act (or any
          similar rule under such Act relating to the disposition of
          securities), or (iii) an opinion of counsel, if such opinion
          shall be reasonably satisfactory to counsel to the issuer,
          that an exemption from registration under such Act is
          available.

          (S)7.2  Piggyback Registration.  If, at any time commencing after the
                  ----------------------                                       
effective date of the offering and expiring seven (7) years thereafter, the
Company proposes to register any of its securities under the Act (other than in
connection with a merger or pursuant to Form S-8) it will give written notice by
registered mail, at least thirty (30) days prior to the filing of each such
registration statement, to the Representative and to all other Holders of the
Warrants and/or the Warrant Securities of its intention to do so.  If the
Representative or other Holders of the Warrants and/or Warrant Securities notify
the Company within twenty (20) business days after receipt of any such notice of
its or their desire to include any such securities in such proposed registration
statement, the Company shall afford the Representative and such Holders of the
Warrants and/or Warrant Securities the opportunity to have any such Warrant
Securities registered under such registration statement.

          Notwithstanding the provisions of this Section 7.2, the Company shall
                                                 -------                       
have the right at any time after it shall have given written notice pursuant to
this Section 7.2 (irrespective of whether a written request for inclusion of any
     -------                                                                    
such securities shall have been

                                       8
<PAGE>
 
made) to elect not to file any such proposed registration statement, or to
withdraw the same after the filing but prior to the effective date thereof.

          If the registration, of which the Company gives notice, is for a
registered public offering involving an underwriting, the Company shall so
advise the Representative and all other Holders of the Warrants and the Warrant
Securities as a part of the written notice given pursuant to this Section 7.2.
                                                                  -------      
In such event, the right of the Holders to participate in such registration
pursuant to this Section 7.2 shall be conditioned upon the Holders'
                 -------                                           
participation in such underwriting and the inclusion of the Holders' Warrant
Securities in the underwriting to the extent provided herein.  The Holders shall
(together with the Company and the other holders of securities of the Company
with contractual registration rights to participate therein in distributing
their securities through such underwriting) enter into an underwriting agreement
in customary form with the representative of the underwriters selected by the
Company.

          If the representative of underwriters advises the Company in writing
that marketing factors require a limitation on the number of shares to be
underwritten, such representative may (subject to the limitations set forth
below) exclude any or all Warrant Securities from, or limit the number of
Warrant Securities to be included in, the registration and underwriting.  The
Company shall so advise all holders of securities requesting registration, and
the number of securities that are entitled to be included in the registration
and underwriting shall be allocated first to the Company for securities being
sold for its own account, second to the Holders pro rata and thereafter among
such other holders pro rata in proportion to the number of securities as to
which they had originally requested registration.  If any such holder does not
agree to the terms of any such underwriting, he shall be excluded therefrom by
written notice from the Company or the underwriter.  If securities are so

                                       9
<PAGE>
 
withdrawn from the registration and if the number of Warrant Securities to be
included in such registration was previously reduced as a result of marketing
factors, the Company shall then offer (subject to the availability of a
reasonable amount of time to make such offer before the commencement of a
distribution) to all persons who have retained the right to include securities
in the registration the right to include additional securities in the
registration in an aggregate amount equal to the number of securities so
withdrawn, with such securities to be allocated among the persons requesting
additional inclusion pro rata in proportion to the number of securities as to
which they had originally requested such registration.

          (S)7.3  Demand Registration.
                  ------------------- 

          (a)  At any time commencing after the effective date of the offering
and expiring five (5) years thereafter, the Holders of the Warrants and/or
Warrant Securities representing a "Majority" (as hereinafter defined) of such
securities (assuming the exercise of all of the Warrants) shall have the right

hereof), exercisable by written notice to the Company, to have the Company
prepare and file with the Commission, on one occasion, a registration statement
and such other documents, including a prospectus, as may be necessary in the
opinion of both counsel for the Company and counsel for the Representative and
Holders, in order to comply with the provisions of the Act, so as to permit a
public offering and sale of their respective Warrant Securities for nine (9)
consecutive months by such Holders and any other Holders of the Warrants and/or
Warrant Securities who notify the Company within ten (10) days after receiving
notice from the Company of such request.

          (b)  The Company covenants and agrees to give written notice of any
registration request under this Section 7.3 by any Holder or Holders to all
                                -------

Warrants and the Warrant Securities within ten (10) days from the date of the
receipt of any such registration request.

          (c)  In addition to the registration rights under Section 7.2 and

and expiring five (5) years thereafter, any Holder of Warrants and/or Warrant
Securities shall have the right, exercisable by written request to the Company,
to have the Company prepare and file, on one occasion, with the Commission a
registration statement so as to permit a public offering and sale for nine (9)
consecutive months by any such Holder of its Warrant Securities provided,
however, that the provisions of Section 7.4(b) hereof shall not apply to any
                                -------                                     
such registration request and registration and all costs incident thereto shall
be at the expense of the Holder or Holders making such request.

          (d)  Notwithstanding anything to the contrary contained herein, if the
Company shall not have filed a registration statement for the Warrant Securities
within the time period specified in Section 7.4(a) hereof pursuant to the
                                    -------

written notice of election of a Majority of the Holders of the Warrants and/or
Warrant Securities, to repurchase (i) any and all Warrant Securities at the

Exercise Price of such Warrant.  Such repurchase shall be in immediately
available funds and shall close within two (2) days after the later of (i) the
expiration of the

Securities to be sold pursuant to any registration statement and each person, if
any, who controls such Holders within the meaning of Section 15 of the Act or

Act"), against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify each of the Underwriters contained in Section 7
                                                                      -------

Agreement pursuant to which the Underwriters have agreed to indemnify the

requiring the Holder(s) to exercise their Warrants prior to the initial filing
of any registration statement or the effectiveness thereof.

          (g)  The Company shall not permit the inclusion of any securities
other than the Warrant Securities to be included in any registration statement
filed pursuant to Section 7.3 hereof, or permit any other registration statement
                  -------                                                       
to be or remain effective during the effectiveness of a registration statement
filed pursuant to Section 7.3 hereof, without the prior written consent of the
                  -------                                                     
Holders of the Warrants and Warrant Securities representing a Majority of such
securities.

          (h)  The Company shall furnish to each Holder participating in the
offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (i) an opinion of counsel to the Company, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (ii) a "cold comfort" letter
dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, a letter dated the date
of the closing under the underwriting agreement) signed by the independent
public accountants who have issued a report on the Company's financial
statements included in such registration statement, in each case covering
substantially the same matters with respect to such registration statement (and
the prospectus included therein) and, in the case of such accountants' letter,
with respect to events subsequent to the date of such financial statements, as
are customarily covered in opinions of issuer's counsel and in accountants'
letters delivered to underwriters in underwritten public offerings of
securities.

          (i) The Company shall as soon as practicable after the effective date
of the registration statement, and in any event within 15 months thereafter,
make "generally available to its security holders" (within the meaning of Rule
158 under the Act) an earnings statement

a period of at least 12 consecutive months beginning after the effective date of
the registration statement.

          (j) The Company shall deliver promptly to each Holder participating in
the offering requesting the correspondence and memoranda described below and to
the managing underwriters, copies of all correspondence between the Commission
and the Company, its counsel or auditors and all memoranda relating to
discussions with the Commission or its staff with respect to the registration
statement and permit each Holder and underwriters to do such investigation, upon
reasonable advance notice, with respect to information contained in or omitted
from the registration statement as it deems reasonably necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. ("NASD").  Such investigation shall include access to books,
records and properties and opportunities to discuss the business of the Company
with its officers and independent auditors, all to such reasonable extent and at
such reasonable times and as often as any such Holder or underwriter shall
reasonably request.

          (k) The Company shall enter into an underwriting agreement with the
managing underwriters selected for such underwriting by Holders holding a
Majority of the Warrant Securities requested to be included in such
underwriting, which may be the Representative.  Such agreement shall be
satisfactory in form and substance to the Company, each Holder and such managing
underwriters, and shall contain such representations, warranties and covenants
by the Company and such other terms as are customarily contained in agreements
of that type used by the managing underwriter.  The Holders shall be parties to
any underwriting agreement relating to an underwritten sale of their Warrant
Securities and may, at their option, require that any or all the
representations, warranties and covenants of the Company to or for the

                                      15

benefit of such underwriters shall also be made to and for the benefit of such
Holders.  Such Holders shall not be required to make any representations or
warranties to or agreements with the Company or the underwriters except as they
may relate to such Holders and their intended methods of distribution.

          (l)  In addition to the Warrant Securities, upon the written request
therefor by any Holder(s), the Company shall include in the registration
statement any other securities of the Company held by such Holder(s) as of the
date of filing of such registration statement, including without limitation
restricted shares of Preferred Stock, Common Stock, options, warrants or any
other securities convertible into shares of Common Stock.

          (m)  For purposes of this Agreement, the term "Majority" in reference
to the Holders of Warrants or Warrant Securities, shall mean in excess of fifty
percent (50%) of the then outstanding Warrants or Warrant Securities (assuming
exercise of all of the Warrants and conversion of all Preferred Shares) that (i)
are not held by the Company, an affiliate, officer, creditor, employee or agent
thereof or any of their respective affiliates, members of their family, persons
acting as nominees or in conjunction therewith and (ii) have not been resold to
the public pursuant to a registration statement filed with the Commission under
the Act.

                                                      -------                 
Warrant Securities issuable upon the exercise at the adjusted Exercise Price of
each Warrant shall be adjusted to the nearest full amount by multiplying a
number equal to the Exercise Price in effect immediately prior to such
adjustment by the number of Warrant Securities issuable upon exercise of the
Warrants immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

          (S)8.4  Definition of Common Stock and Preferred Stock.  (a)  For the
                  ----------------------------------------------               
purpose of this Agreement, the term "Common Stock" shall mean (i) the class of
stock designated as Common Stock in the Articles of Incorporation of the Company
as may be amended as of the date hereof, or (ii) any other class of stock
resulting from successive changes or reclassifications of such Common Stock
consisting solely of changes in par value, or from par value to no par value, or
from no par value to par value.

                  (b)  For the purpose of this Agreement, the term "Preferred
Stock" shall mean the Preferred Stock purchased by the Underwriters for resale
to the public in the Public Offering pursuant to the terms of the Underwriting
Agreement, as such Preferred Stock is more particularly described in the
Certificate of Designation incorporated therein, as the same may be amended from
time to time. The Preferred Shares issuable upon exercise of the
Representative's Warrants shall be identical to the Preferred Stock described in
the Certificate

                                      17
<PAGE>
 
of Designation [except that such Preferred Shares cannot be redeemed.]  In the
event of any change after the date hereof in the conversion ratio (or effective
conversion price) or, the time period for conversion of, or the number or class
of securities issuable upon conversion of, the Preferred Stock, the Holder of
any Representative's Warrant shall receive upon exercise thereof Preferred
Shares with a conversion ratio (and an effective conversion price) equal to the
conversion ratio (and an effective conversion price) then in effect for,
convertible for such number and class of securities as would be issuable upon
the conversion of, and convertible for such period of time as, Preferred Stock
issued and outstanding on the date hereof after giving effect to such change.
In addition, in the event that the Company grants to the holders of Preferred
Stock upon the exercise thereof any benefits or inducements not set forth in the
Certificate of Designation, the Holder shall be entitled to receive such benefit
or inducement upon the exercise by such Holder of any Representative's Warrant
to purchase Preferred Shares.

                  -----------------------                                      
Company with, or merger of the Company with, or merger of the Company into,
another corporation (other than a consolidation or merger which does not result
in any reclassification or change of the outstanding Common Stock or Preferred
Stock or other securities issuable upon exercise of the Warrants or conversion
of the Preferred Stock), or in the case of any sale or conveyance to another
person, corporation or other entity of the property of the Company as an
entirety or substantially as an entirety, then, as a condition of such
consolidation, merger, sale or conveyance, the Company or such successor or
purchasing entity, as the case may be, the corporation formed by such
consolidation or merger shall execute and deliver to the Holder a supplemental
warrant agreement providing that the holder of each Warrant then outstanding or

                                      18
<PAGE>
 
to be outstanding shall have the right thereafter (until the expiration of such
Warrant) to receive, upon exercise of such warrant, the kind and amount of
shares of stock and other securities and property receivable upon such
consolidation or merger, by a holder of the number of shares of Common Stock of
the Company for which such warrant might have been exercised immediately prior
to such consolidation, merger, sale or transfer.  Such supplemental warrant
agreement shall provide for adjustments which shall be identical to the
adjustments provided in Section 8.  The above provision of this subsection shall

          Warrants or the shares of Preferred Stock or the shares of Common
          Stock issuable upon the exercise of (i) the Warrants, or (ii) the
          Redeemable Warrants; or

                  (b)  If the amount of said adjustment shall be less than ten
          cents (10c) per Warrant Security, provided, however, that in such case
          any adjustment that would otherwise be required then to be made shall
          be carried forward and shall be made at the time of and together with
          the next subsequent adjustment which, together with any adjustment so
          carried forward, shall amount to at least ten cents (10c) per Warrant
          Security.

the number of shares of Common Stock underlying

                                      19

Section 8 of the Warrant Agreement between the Company and Continental Stock
- -------                                                                     
Transfer & Trust Company dated as of the date hereof (the "Redeemable Warrant
Agreement"), upon the occurrence of any of the events described therein.
Thereafter, the underlying Redeemable Warrants shall be (exercisable at such
adjusted Redeemable Warrant exercise price for such adjusted number of
underlying shares of Common Stock or other securities, properties or rights.

          9.  Exchange and Replacement of Warrant Certificates.  Each Warrant
              ------------------------------------------------               
Certificate is exchangeable without expense, upon the surrender thereof by the
registered Holder at the principal executive office of the Company, for a new
Warrant Certificate of like tenor and date representing in the aggregate the
right to purchase the same number of Warrant Securities in such denominations as
shall be designated by the Holder thereof at the time of such surrender.

          Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if

              -----------------------------------                           
required to issue certificates representing fractions of shares of Preferred
Stock or Common Stock or Redeemable Warrants, as the case may be, upon the
exercise of the Warrants or the shares of Common Stock issuable upon exercise of
the Redeemable Warrants underlying the Warrants, nor shall it be required to
issue scrip or pay cash in lieu of fractional interests, it being the

                                      20
<PAGE>
 
intent of the parties that all fractional interests shall be eliminated by
rounding any fraction up to the nearest whole number of shares of Preferred
Stock or Common Stock or Redeemable Warrants, as the case may be, or other
securities, properties or rights.

          11.  Reservation and Listing of Securities.  The Company shall at all
               -------------------------------------                           
times reserve and keep available out of its authorized shares of Common Stock,
solely for the purpose of issuance upon the exercise of the Warrants and
Redeemable Warrants, such number of shares of Preferred Stock and Common Stock
or other securities, properties or rights as shall be issuable upon conversion
thereof.  The Company covenants and agrees that, upon exercise of the Warrants
and payment of the Exercise Price therefor as applicable, and/or the subsequent
conversion of the Preferred Shares, all shares of Preferred Stock and Common
Stock and other securities issuable upon such exercise shall be duly and validly
issued, fully paid, non-assessable and not subject to the preemptive rights of
any stockholder.  The Company further covenants and agrees that, upon exercise
of the Redeemable Warrants underlying the Warrants and payment of the respective
Redeemable Warrant exercise price therefor, all shares of Common Stock and other
securities issuable upon such exercises shall be duly and validly issued, fully
paid, non-assessable and not subject to the pre-emptive rights of any
stockholder.  As long as the Warrants shall be outstanding, the Company shall
use its best efforts to cause all shares of Preferred Stock and Common Stock and
Redeemable Warrants issuable upon the exercise of the Warrants and Redeemable
Warrants and all shares of Common Stock issuable upon conversion of the
Preferred Shares to be listed (subject to official notice of issuance) on all
securities exchanges on which the Preferred Stock and/or Common Stock and/or the
Redeemable Warrants issued to the public in connection herewith may then be
listed and/or quoted on NSM or NNM.

               --------------------------                                      
shall be construed as conferring upon the Holders the right to vote or to
consent or to receive notice as a stockholder in respect of any meetings of
stockholders for the election of directors or any other matter, or as having any
rights whatsoever as a stockholder of the Company.  If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

               (a) the Company shall take a record of the holders of its shares
          of Common Stock for the purpose of entitling them to receive a
          dividend or distribution payable otherwise than in cash, or a cash
          dividend or distribution payable otherwise than out of current or
          retained earnings, as indicated by the accounting treatment of such
          dividend or distribution on the books of the Company; or

               (b) the Company shall offer to all the holders of its Common
          Stock any additional shares of capital stock of the Company or
          securities convertible into or exchangeable for shares of capital
          stock of the Company, or any option, right or warrant to subscribe
          therefor; or

               (c) a dissolution, liquidation or winding up of the Company
          (other than in connection with a consolidation or merger) or a sale of
          all or substantially all of its property, assets and business as an
          entirety shall be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
stockholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, or entitled to vote on such

                                      22
<PAGE>
 
proposed dissolution, liquidation, winding up or sale.  Such notice shall
specify such record date or the date of closing the transfer books, as the case
may be.  Failure to give such notice or any defect therein shall not affect the
validity of any action taken in connection with the declaration or payment of
any such dividend, or the issuance of any convertible or exchangeable
securities, or subscription rights, options or warrants, or any proposed
dissolution, liquidation, winding up or sale.

          13.  Redeemable Warrants.
               ------------------- 

          The form of the certificate representing Redeemable Warrants (and the
form of election to purchase shares of Common Stock upon the exercise of
Redeemable Warrants and  the form of assignment printed on the reverse thereof)
shall be substantially as set forth in Exhibit "A" to the Redeemable Warrant
Agreement.  Each Redeemable Warrant issuable upon exercise of the Warrants shall

[13 months from the date of the Prospectus] until 5:30 p.m. New York time on
__________, 1999 [36 months from the date of the Prospectus] at which time the
Redeemable Warrants, unless the exercise period has been extended, shall expire.
The exercise price of the Redeemable Warrants and the number of shares of Common
Stock issuable upon the exercise of the Redeemable Warrants are subject to
adjustment, whether or not the Warrants have been exercised and the Redeemable
Warrants have been issued, in the manner and upon the occurrence of the events
set forth in Section 8 of the Redeemable Warrant Agreement, which is hereby
             -------

entirety herein.  Subject to the provisions of this Agreement and upon issuance

Warrant shall have the right to purchase from the Company (and the Company shall
issue to such registered holders) up to the number of fully paid and non-
assessable shares of Common Stock (subject to adjustment as provided herein and
in the Redeemable Warrant Agreement), free and clear of all preemptive rights of
stockholders, provided that such registered holder complies with the terms
governing exercise of the Redeemable Warrant set forth in the Redeemable Warrant
Agreement, and pays the applicable exercise price, determined in accordance with
the terms of the Redeemable Warrant Agreement.  Upon exercise of the Redeemable
Warrants, the Company shall forthwith issue to the registered holder of any such
Redeemable Warrant in his name or in such name as may be directed by him,
certificates for the number of shares of Common Stock so purchased.  Except as
otherwise provided in this Agreement, the Redeemable Warrants underlying the
Warrants shall be governed in all respects by the terms of the Redeemable
Warrant Agreement.  The Redeemable Warrants shall be transferable in the manner
provided in the Redeemable Warrant Agreement, and upon any such transfer, a new
Redeemable Warrant Certificate shall be issued promptly to the transferee.  The
Company covenants to, and agrees with the Holder(s) that without the prior
written consent of the Holder(s), which will not be unreasonably withheld, the
Redeemable Warrant Agreement will not be modified, amended, canceled, altered or
superseded, and that the Company will send to each Holder, irrespective of
whether or not the Warrants have been exercised, any and all notices required by
the Redeemable Warrant Agreement to be sent to holders of Redeemable Warrants.

     SECTION 3.  Form and Execution of Warrant Certificates.
                 ------------------------------------------ 

          (a)    The Warrant Certificates shall be substantially in the form
annexed hereto as Exhibit A (the provisions of which are hereby incorporated
                  -------                                                   
herein) and may have such letters, numbers or other marks of identification or
designation and such legends, summaries or endorsements printed, lithographed or
engraved thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any stock exchange on which the Warrants may be listed, or to
conform to usage.  The Warrant Certificates shall be dated the date of issuance
thereof (whether upon initial issuance, transfer, exchange or in lieu of
mutilated, lost, stolen or destroyed Warrant Certificates).

                                       7

          (b)    Warrant Certificates shall be executed on behalf of the Company
by its Chairman of the Board, President or any Vice President and by its
Treasurer or an Assistant Treasurer or its Secretary or an Assistant Secretary,
by manual signatures or by facsimile signatures printed thereon, and shall have
imprinted thereon a facsimile of the Company's seal. Warrant Certificates shall
be manually countersigned by the Warrant Agent and shall not be valid for any
purpose unless so countersigned. In case any officer of the Company who shall
have signed any of the Warrant Certificates shall cease to be such officer of
the Company before the date of issuance of the Warrant Certificates or before
countersignature by the Warrant Agent and issue and delivery thereof, such
Warrant Certificates, nevertheless, may be countersigned by the Warrant Agent
and issued and delivered with the same force and effect as though the officer of
the Company who signed such Warrant Certificates had not ceased to hold such
office.

     SECTION 4.  Exercise.
                 -------- 

          (a)    Warrants in denominations of one or whole number multiples
thereof may be exercised commencing at any time on or after the Initial Warrant
Exercise Date, but not after the Warrant Expiration Date, upon the terms and
subject to the conditions set forth herein (including the provisions set forth
in Sections 5 and 9 hereof) and in the applicable Warrant Certificate. A Warrant
   --------
shall be deemed to have been exercised immediately prior to the close of
business on the Exercise Date, provided that the Warrant Certificate
representing such Warrant, with the exercise form thereon duly executed by the
Registered Holder thereof or his attorney duly authorized in writing, together
with payment in cash or by check made payable to the Warrant Agent for the
account of the Company of an amount in lawful money of the United States of
America equal to the applicable Purchase Price, have been received

                                       8
<PAGE>
 
by the Warrant Agent.  The person entitled to receive the securities deliverable
upon such exercise shall be treated for all purposes as the holder of such
securities as of the close of business on the Exercise Date.  As soon as
practicable on or after the Exercise Date and in any event within five (5)
business days after such date, the Warrant Agent, on behalf of the Company,
shall cause to be issued to the person or persons entitled to receive the same a
Common Stock certificate or certificates for the shares of Common Stock
deliverable upon such exercise, and the Warrant Agent shall deliver the same to
the person or persons entitled thereto.  Upon the exercise of any Warrants, the
Warrant Agent shall promptly notify the Company in writing of such fact and of
the number of securities delivered upon such exercise and, subject to Section
                                                                      -------
4(b) hereof, shall cause all payments in cash or by check made payable to the
order of the Company in respect of the Purchase Price to be deposited promptly
in the Company's bank account or delivered to the Company.

          (b)    At any time upon the exercise of any Warrants after __________,
1997 [the 1st anniversary of the effective date of the Registration Statement],
the Warrant Agent shall, on a daily basis, within two (2) business days after
any such exercise, notify the Underwriter or its successors or assigns of the
exercise of any such Warrants and shall, on a weekly basis (subject to
collection of funds constituting the tendered Purchase Price, but in no event
later than five (5) business days after the last day of the calendar week in
which such funds were tendered), remit to the Underwriter or its successors or
assigns an amount equal to five percent (5%) of the Purchase Price of such
Warrants being then exercised unless the Underwriter or its successors or
assigns shall have notified the Warrant Agent that the payment of such amount
with respect to any such Warrant is violative of the rules and regulations
promulgated under the Exchange Act, the rules and regulations of the NASD or

                                       9
<PAGE>
 
applicable state securities or "blue sky" laws, or the Warrants are those
underlying the Representative's Warrants, in any of which events the Warrant
Agent shall have to pay such amount to the Company; provided, however, that the
                                                    --------  -------          
Warrant Agent shall not be obligated to pay any amounts pursuant to this Section
                                                                         -------
4(b) during any week that such amounts payable are less than one thousand
dollars ($1,000) and the Warrant Agent's obligation to make such payments shall
be suspended until the amount payable aggregates one thousand dollars ($1,000),
and provided further, that, in any event, any such payment (regardless of
amount) shall be made not less frequently than monthly.

          (c)    The Company shall not be obligated to issue any fractional
share interests or fractional warrant interests upon the exercise of any Warrant
or Warrants, nor shall it be obligated to issue scrip or pay cash in lieu of
fractional interests. Any fraction equal to or greater than one-half (1/2) shall
be rounded up to the next full share or Warrant, as the case may be. Any
fraction less than one-half shall be eliminated.

     SECTION 5.  Reservation of Shares, Listing, Payment of Taxes, etc.
                 ------------------------------------------------------

          (a)    The Company covenants that it will at all times reserve and
keep available out of its authorized Common Stock, solely for the purpose of
issuance upon the exercise of Warrants, such number of shares of Common Stock as
shall then be issuable upon the exercise of all outstanding Warrants. The
Company covenants that, upon exercise of the Warrants and payment of the
Purchase Price for the shares of Common Stock underlying the Warrants, all
shares of Common Stock which shall be issuable upon such exercise shall be duly
and validly issued, fully paid, non-assessable, free from all preemptive or
similar rights, and free from all taxes, liens and charges with respect to the
issuance thereof, and that upon issuance such shares shall be listed or quoted
on each securities

                                      10
<PAGE>
 
exchange, if any, on which the other shares of outstanding Common Stock are then
listed or quoted, or if not then so listed or quoted on each place (whether the
Nasdaq Stock Market, Inc., the NASD Over-the-Counter Bulletin Board, the
National Quotation Bulletin Board "Pink Sheets" or otherwise) on which the other
shares of outstanding Common Stock are listed or quoted.

          (b)    The Company covenants that if any securities reserved for the
purpose of exercise of Warrants hereunder require registration with, or approval
of, any governmental authority under any federal securities law before such
securities may be validly issued or delivered upon such exercise, then the
Company will file a registration statement under the federal securities laws or
a post-effective amendment to a registration statement, use its best efforts to
cause the same to become effective, keep such registration statement current
while any of the Warrants are outstanding and deliver a prospectus which
complies with Section 10(a)(3) of the Act, to the Registered Holder exercising
the Warrant (except, if in the opinion of counsel to the Company, such
registration is not required under the federal securities law or if the Company
receives a letter from the staff of the Commission stating that it would not
take any enforcement action if such registration is not effected).  The Company
will use its best efforts to obtain appropriate approvals or registrations under
the state "blue sky" securities laws of all states in which Registered Holders
reside.  Warrants may not be exercised by, nor may shares of Common Stock be
issued to, any Registered Holder in any state in which such exercise would be
unlawful.

          (c)    The Company shall pay all documentary, stamp or similar taxes
and other governmental charges that may be imposed with respect to the issuance
of Warrants, or the issuance or delivery of any shares of Common Stock upon
exercise of the Warrants;

                                      11
<PAGE>
 
provided, however, that if shares of Common Stock are to be delivered in a name
- --------  -------                                                              
other than the name of the Registered Holder of the Warrant Certificate
representing any Warrant being exercised, then no such delivery shall be made
unless the person requesting the same has paid to the Warrant Agent the amount
of transfer taxes or charges incident thereto, if any.

          (d)    The Warrant Agent is hereby irrevocably authorized as the
Transfer Agent to requisition from time to time certificates representing shares
of Common Stock or other securities required upon exercise of the Warrants, and
the Company will comply with all such requisitions.

     SECTION 6.  Exchange and Registration of Transfer.
                 ------------------------------------- 

          (a)    Warrant Certificates may be exchanged for other Warrant
Certificates representing an equal aggregate number of Warrants or may be
transferred in whole or in part.  Warrant Certificates to be so exchanged shall
be surrendered to the Warrant Agent at its Corporate Office, and the Company
shall execute and the Warrant Agent shall countersign, issue and deliver in
exchange therefor the Warrant Certificate or Certificates which the Registered
Holder making the exchange shall be entitled to receive.

          (b)    The Warrant Agent shall keep, at such office, books in which,
subject to such reasonable regulations as it may prescribe, it shall register
Warrant Certificates and the transfer thereof.  Upon due presentment for
registration of transfer of any Warrant Certificate at such office, the Company
shall execute and the Warrant Agent shall issue and deliver to the transferee or
transferees a new Warrant Certificate or Certificates representing an equal
aggregate number of Warrants.

          (c)    With respect to any Warrant Certificates presented for
registration of transfer, or for exchange or exercise, the subscription or
assignment form, as the case may

                                      12
<PAGE>
 
be, on the reverse thereof shall be duly endorsed or be accompanied by a written
instrument or instruments of subscription or assignment, in form satisfactory to
the Company and the Warrant Agent, duly executed by the Registered Holder
thereof or his attorney duly authorized in writing.

          (d)    No service charge shall be made for any exchange or
registration of transfer of Warrant Certificates. However, the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection therewith.

          (e)    All Warrant Certificates surrendered for exercise or for
exchange shall be promptly cancelled by the Warrant Agent.

          (f)    Prior to due presentment for registration or transfer thereof,
the Company and the Warrant Agent may deem and treat the Registered Holder of
any Warrant Certificate as the absolute owner thereof of each Warrant
represented thereby (notwithstanding any notations of ownership or writing
thereon made by anyone other than the Company or the Warrant Agent) for all
purposes and shall not be affected by any notice to the contrary.

     SECTION 7.  Loss or Mutilation.  Upon receipt by the Company and the
                 ------------------
Warrant Agent of evidence satisfactory to them of the ownership of and the loss,
theft, destruction or mutilation of any Warrant Certificate and (in the case of
loss, theft or destruction) of indemnity satisfactory to them, and (in case of
mutilation) upon surrender and cancellation thereof, the Company shall execute
and the Warrant Agent shall countersign and deliver in lieu thereof a new
Warrant Certificate representing an equal number of Warrants. Applicants

                                      13
<PAGE>
 
for a substitute Warrant Certificate shall also comply with such other
reasonable regulations and pay such other reasonable charges as the Warrant
Agent may prescribe.

     SECTION 8.  Adjustment of Purchase Price and Number of Shares of Common
                 -----------------------------------------------------------
Stock Deliverable.
- ----------------- 

          (a)    (i) Except as hereinafter provided, in the event the Company
shall, at any time or from time to time after the date hereof, sell any shares
of Common Stock for a consideration per share less than the Purchase Price or
issue any shares of Common Stock as a stock dividend to the holders of Common
Stock, or subdivide or combine the outstanding shares of Common Stock into a
greater or lesser number of shares (any such sale, issuance, subdivision or
combination being herein called a "Change of Shares"), then, and thereafter upon
each further Change of Shares, the Purchase Price for the Warrants (whether or
not the same shall be issued and outstanding) in effect immediately prior to
such Change of Shares shall be changed to a price (including any applicable
fraction of a cent to the nearest cent) determined by dividing (A) the sum of
(x) the total number of shares of Common Stock outstanding immediately prior to
such Change of Shares, multiplied by the Purchase Price in effect immediately
prior to such Change of Shares, and (y) the consideration, if any, received by
the Company upon such sale, issuance, subdivision or combination by (B) the
total number of shares of Common Stock outstanding immediately after such Change
of Shares; provided, however, that in no event shall the Purchase Price be
           --------  -------                                              
adjusted pursuant to this computation to an amount in excess of the Purchase
Price in effect immediately prior to such computation, except in the case of a
combination of outstanding shares of Common Stock.

     For the purposes of any adjustment to be made in accordance with this
Section 8(a)(i) the following provisions shall be applicable:
- -------                                                      

                                      14
<PAGE>
 
                 (A)  In case of the issuance or sale of shares of Common Stock
(or of other securities deemed hereunder to involve the issuance or sale of
shares of Common Stock) for a consideration part or all of which shall be cash,
the amount of the cash portion of the consideration therefor deemed to have been
received by the Company shall be (i) the subscription price, if shares of Common
Stock are offered by the Company for subscription, or (ii) the public offering
price (before deducting therefrom any compensation paid or discount allowed in
the sale, underwriting or purchase thereof by underwriters or dealers or others
performing similar services, or any expenses incurred in connection therewith),
if such securities are sold to underwriters or dealers for public offering
without a subscription offering, or (iii) the gross amount of cash actually
received by the Company for such securities, in any other case.

                 (B)  In case of the issuance or sale (otherwise than as a
dividend or other distribution on any stock of the Company, and otherwise than
on the exercise of options, rights or warrants or the conversion or exchange of
convertible or exchangeable securities) of shares of Common Stock (or of other
securities deemed hereunder to involve the issuance or sale of shares of Common
Stock) for a consideration part or all of which shall be other than cash, the
amount of the consideration therefor other than cash deemed to have been
received by the Company shall be the value of such consideration as determined
in good faith by the Board of Directors of the Company on the basis of a record
of values of similar property or services.

                 (C)  Shares of Common Stock issuable by way of dividend or
other distribution on any stock of the Company shall be deemed to have been
issued immediately after the opening of business on the day following the record
date for the determination of

                                      15
<PAGE>
 
shareholders entitled to receive such dividend or other distribution and shall
be deemed to have been issued without consideration.

                 (D)  The reclassification of securities of the Company other
than shares of Common Stock into securities including shares of Common Stock
shall be deemed to involve the issuance of such shares of Common Stock for a
consideration other than cash immediately prior to the close of business on the
date fixed for the determination of security holders entitled to receive such
shares, and the value of the consideration allocable to such shares of Common
Stock shall be determined as provided in subsection (B) of this Section 8(a)(i).
                                                                -------         
                 (E)  The number of shares of Common Stock at any one time
outstanding shall be deemed to include the aggregate maximum number of shares
issuable (subject to readjustment upon the actual issuance thereof) upon the
exercise of options, rights or warrants and upon the conversion or exchange of
convertible or exchangeable securities.

          (ii)   Upon each adjustment of the Purchase Price pursuant to this
Section 8, the number of shares of Common Stock purchasable upon the exercise of
- -------                                                                         
each Warrant shall be the number derived by multiplying the number of shares of
Common Stock purchasable immediately prior to such adjustment by the Purchase
Price in effect prior to such adjustment and dividing the product so obtained by
the applicable adjusted Purchase Price.

          (b)    In case the Company shall at any time after the date hereof
issue options, rights or warrants to subscribe for shares of Common Stock, or
issue any securities convertible into or exchangeable for shares of Common
Stock, for a consideration per share (determined as provided in Section 8(a)(i)
                                                                -------
hereof and as provided below) less than the

                                      16
<PAGE>
 
Purchase Price in effect immediately prior to the issuance of such options,
rights or warrants, or such convertible or exchangeable securities, or without
consideration (including the issuance of any such securities by way of dividend
or other distribution), the Purchase Price for the Warrants (whether or not the
same shall be issued and outstanding) in effect immediately prior to the
issuance of such options, rights or warrants, or such convertible or
exchangeable securities, as the case may be, shall be reduced to a price
determined by making the computation in accordance with the provisions of
Section 8(a)(i) hereof, provided that:
- -------                               

                 (A)  The aggregate maximum number of shares of Common Stock, as
the case may be, issuable or that may become issuable under such options, rights
or warrants (assuming exercise in full even if not then currently exercisable or
currently exercisable in full) shall be deemed to be issued and outstanding at
the time such options, rights or warrants were issued, for a consideration equal
to the minimum purchase price per share provided for in such options, rights or
warrants at the time of issuance, plus the consideration, if any, received by
the Company for such options, rights or warrants; provided, however, that upon
                                                  --------  -------           
the expiration or other termination of such options, rights or warrants, if any
thereof shall not have been exercised, the number of shares of Common Stock
deemed to be issued and outstanding pursuant to this subsection (A) (and for the
purposes of subsection (E) of Section 8(a)(i) hereof) shall be reduced by the
                              -------                                        
number of shares as to which options, warrants and/or rights shall have expired,
and such number of shares shall no longer be deemed to be issued and
outstanding, and the Purchase Price then in effect shall forthwith be readjusted
and thereafter be the price that it would have been had adjustment been made on
the basis of the issuance only of the shares actually issued plus the

                                      17
<PAGE>
 
shares remaining issuable upon the exercise of those options, rights or warrants
as to which the exercise rights shall not have expired or terminated
unexercised.

                 (B)  The aggregate maximum number of shares of Common Stock
issuable or that may become issuable upon conversion or exchange of any
convertible or exchangeable securities (assuming conversion or exchange in full
even if not then currently convertible or exchangeable in full) shall be deemed
to be issued and outstanding at the time of issuance of such securities, for a
consideration equal to the consideration received by the Company for such
securities, plus the minimum consideration, if any, receivable by the Company
upon the conversion or exchange thereof; provided, however, that upon the
                                         --------  -------
termination of the right to convert or exchange such convertible or exchangeable
securities (whether by reason of redemption or otherwise), the number of shares
of Common Stock deemed to be issued and outstanding pursuant to this subsection
(B) (and for the purposes of subsection (E) of Section 8(a)(i) hereof) shall be
                                               -------  
reduced by the number of shares as to which the conversion or exchange rights
shall have expired or terminated unexercised, and such number of shares shall no
longer be deemed to be issued and outstanding, and the Purchase Price then in
effect shall forthwith be readjusted and thereafter be the price that it would
have been had adjustment been made on the basis of the issuance only of the
shares actually issued plus the shares remaining issuable upon conversion or
exchange of those convertible or exchangeable securities as to which the
conversion or exchange rights shall not have expired or terminated unexercised.

                 (C)  If any change shall occur in the price per share provided
for in any of the options, rights or warrants referred to in subsection (A) of
this Section 8(b), or in the price per share or ratio at which the securities
     -------                                                                 
referred to in subsection (B) of this

                                      18
<PAGE>
 
Section 8(b) are convertible or exchangeable, such options, rights or warrants
- -------                                                                       
or conversion or exchange rights, as the case may be, to the extent not
theretofore exercised, shall be deemed to have expired or terminated on the date
when such price change became effective in respect of shares not theretofore
issued pursuant to the exercise or conversion or exchange thereof, and the
Company shall be deemed to have issued upon such date new options, rights or
warrants or convertible or exchangeable securities.

          (c)    In case of any reclassification or change of outstanding shares
of Common Stock issuable upon exercise of the Warrants (other than a change in
par value, or from par value to no par value, or from no par value to par value
or as a result of a subdivision or combination), or in case of any consolidation
or merger of the Company with or into another corporation (other than a merger
with a Subsidiary in which merger the Company is the continuing corporation and
which does not result in any reclassification or change of the then outstanding
shares of Common Stock or other capital stock issuable upon exercise of the
Warrants), or in case of any sale or conveyance to another corporation of the
property of the Company as an entirety or substantially as an entirety, then, as
a condition of such reclassification, change, consolidation, merger, sale or
conveyance, the Company, or such successor or purchasing corporation, as the
case may be, shall make lawful and adequate provision whereby the Registered
Holder of each Warrant then outstanding shall have the right thereafter to
receive on exercise of such Warrant the kind and amount of securities and
property receivable upon such reclassification, change, consolidation, merger,
sale or conveyance by a holder of the number of securities issuable upon
exercise of such Warrant immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance and shall forthwith file at the
Corporate Office of the Warrant Agent a statement

                                      19
<PAGE>
 
signed by its Chairman of the Board, President or a Vice President and by its
Treasurer or an Assistant Treasurer or its Secretary or an Assistant Secretary
evidencing such provision.  Such provisions shall include provision for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in Sections 8(a) and 8(b) hereof.  The above provisions
                            --------                                            
of this Section 8(c) shall similarly apply to successive reclassifications and
        -------                                                               
changes of shares of Common Stock and to successive consolidations, mergers,
sales or conveyances.

          (d)    Irrespective of any adjustments or changes in the Purchase
Price or the number of shares of Common Stock purchasable upon exercise of the
Warrants, the Warrant Certificates theretofore and thereafter issued shall,
unless the Company shall exercise its option to issue new Warrant Certificates
pursuant to Section 2(e) hereof, continue to express the Purchase Price per
            -------                                                        
share and the number of shares purchasable thereunder as the Purchase Price per
share and the number of shares purchasable thereunder were expressed in the
Warrant Certificates when the same were originally issued.

          (e)    After each adjustment of the Purchase Price pursuant to this
Section 8, the Company will promptly prepare a certificate signed by the
- -------                                                                 
Chairman of the Board, President, or a Vice President and by the Treasurer or an
Assistant Treasurer or the Secretary or an Assistant Secretary of the Company
setting forth: (i) the Purchase Price as so adjusted, (ii) the number of shares
of Common Stock purchasable upon exercise of each Warrant, after such
adjustment, and (iii) a brief statement of the facts accounting for such
adjustment.  The Company will promptly file such certificate with the Warrant
Agent and cause a brief summary thereof to be sent by ordinary first class mail
to each Registered Holder at his last address as it shall appear on the registry
books of the Warrant Agent.  No

<PAGE>
 
failure to mail such notice nor any defect therein or in the mailing thereof
shall affect the validity thereof except as to the holder to whom the Company
failed to mail such notice, or except as to the holder whose notice was
defective.  The affidavit of an officer of the Warrant Agent or the Secretary or
an Assistant Secretary of the Company that such notice has been mailed shall, in
the absence of fraud, be prima facie evidence of the facts stated therein.

          (f)    No adjustment of the Purchase Price shall be made as a result
of or in connection with (A) the issuance or sale of shares of Common Stock
pursuant to options, warrants, stock purchase agreements and convertible or
exchangeable securities outstanding or in effect on the date hereof, (B) the
issuance or sale of shares of Common Stock upon the exercise of any "incentive
stock options" (as such term is defined in the Internal Revenue Code of 1986, as
amended), whether or not such options were outstanding on the date hereof, or
(C) the issuance or sale of shares of Common Stock if the amount of said
adjustment shall be less than ten cents ($.10); provided, however, that in such
                                                --------  -------              
case, any adjustment that would otherwise be required then to be made shall be
carried forward and shall be made at the time of and together with the next
subsequent adjustment that shall amount, together with any adjustment so carried
forward, to at least ten cents ($.10).  In addition, Registered Holders shall
not be entitled to cash dividends paid by the Company prior to the exercise of
any Warrant or Warrants held by them.

     SECTION 9.  Redemption.
                 ---------- 

          (a)    Commencing on the Initial Warrant Redemption Date, the Company

ten cents ($.10) per

                                      21
<PAGE>
 
Warrant; provided, however, that before any such call for redemption of Warrants
         --------  -------                                                      
can take place, the (i) closing bid price for the Common Stock, as reported by
the National Association of Securities Dealers Automated Quotation System, or
(ii) if not so quoted, as reported by any other recognized quotation system on
which the Common Stock is quoted, shall have for any twenty (20) trading days
within a period of thirty (30) consecutive trading days ending on the tenth
(10th) trading day prior to the date on which the notice contemplated by
Sections 9(b) and 9(c) hereof is given, equalled or exceeded __________ dollars
- --------                                                                       
($__________) [200% of the conversion price of the Preferred Stock] per share of
Common Stock (subject to adjustment in the event of any stock splits or other
similar events as provided in Section 8 hereof).
                              -------           

          (b)    In case the Company shall exercise its right to redeem all of
the Warrants, it shall give or cause to be given notice to the Registered
Holders of the Warrants, by mailing to such Registered Holders a notice of
redemption, first class, postage prepaid, at their last address as shall appear
on the records of the Warrant Agent. Any notice mailed in the manner provided
herein shall be conclusively presumed to have been duly given whether or not the
Registered Holder receives such notice. Not less than five (5) business days
prior to the mailing to the Registered Holders of the Warrants of the notice of
redemption, the Company shall deliver or cause to be delivered to the
Underwriter or its successors or assigns a similar notice telephonically and
confirmed in writing, together with a list of the Registered Holders (including
their respective addresses and number of Warrants beneficially owned by them) to
whom such notice of redemption has been or will be given.

          (c)    The notice of redemption shall specify (i) the redemption
price, (ii) the date fixed for redemption, which shall in no event be less than
thirty (30) days after the

                                      22
<PAGE>
 
date of mailing of such notice, (iii) the place where the Warrant Certificates
shall be delivered and the redemption price shall be paid, (iv) that the
Underwriter or its successors or assigns is the Company's exclusive warrant
solicitation agent and shall receive the commission contemplated by Section 4(b)
                                                                    -------     
hereof, and (v) that the right to exercise the Warrant shall terminate at 5:00
p.m. (New York time) on the business day immediately preceding the date fixed
for redemption.  The date fixed for the redemption of the Warrants shall be the
"Redemption Date" for purposes of this Agreement.  No failure to mail such
notice nor any defect therein or in the mailing thereof shall affect the
validity of the proceedings for such redemption except as to a holder (A) to
whom notice was not mailed or (B) whose notice was defective.  An affidavit of
the Warrant Agent or the Secretary or Assistant Secretary of the Company that
notice of redemption has been mailed shall, in the absence of fraud, be prima
facie evidence of the facts stated therein.

          (d)    Any right to exercise a Warrant shall terminate at 5:00 p.m.
(New York time) on the business day immediately preceding the Redemption Date.
The redemption price payable to the Registered Holders shall be mailed to such
persons at their addresses of record.

          (e)    The Company shall indemnify the Underwriter and each person, if
any, who controls the Underwriter within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act against all loss, claim, damage, expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which any of them may
become subject under the Act, the Exchange Act or otherwise arising out of the
registration statement or prospectus referred to in Section 5(b) hereof to the
                                                    -------                   
same extent and with the same effect (including the provisions regarding

                                      23
<PAGE>
 
contribution) as the provisions pursuant to which the Company has agreed to
indemnify the Underwriter contained in Section 7 of the Underwriting Agreement.

          (f)    Five (5) business days prior to the Redemption Date, the
Company shall furnish to the Underwriter (i) an opinion of counsel to the
Company, dated such date and addressed to the Underwriter, and (ii) a "cold
comfort" letter dated such date addressed to the Underwriter, signed by the
independent public accountants who have issued a report on the Company's
financial statements included in the registration statement referred to in
Section 5(b) hereof, in each case covering substantially the same matters with
- -------                
respect to such registration statement (and the prospectus included therein)
and, in the case of such accountants' letter, with respect to events subsequent
to the date of such financial statements, as are customarily covered in opinions
of issuer's counsel and in accountants' letters delivered to underwriters in
underwritten public offerings of securities, including, without limitation,
those matters covered in Sections 6(d) and (i) of the Underwriting Agreement.

          (g)    The Company shall as soon as practicable after the Redemption
Date, and in any event within fifteen (15) months thereafter, make "generally
available to its security holders" (within the meaning of Rule 158 under the
Act) an earnings statement (which need not be audited) complying with Section
11(a) of the Act and covering a period of at least twelve (12) consecutive
months beginning after the Redemption Date.

          (h)    The Company shall deliver within five (5) business days prior
to the Redemption Date copies of all correspondence between the Commission and
the Company, its counsel or auditors and all memoranda relating to discussions
with the Commission or its staff with respect to the registration statement
referred to in Section 5(b) hereof and permit the Underwriter to do such
               -------
investigation, upon reasonable advance notice, with respect to

                                      24
<PAGE>
 
information contained in or omitted from the registration statement as it deems
reasonably necessary to comply with applicable securities laws or the rules of
the NASD.  Such investigation shall include access to books, records and
properties and opportunities to discuss the business of the Company with its
officers and independent auditors, all to such reasonable extent and at such
reasonable times and as often as the Underwriter shall reasonably request.

     SECTION 10. Concerning the Warrant Agent.
                 ---------------------------- 

          (a)    The Warrant Agent acts hereunder as agent and in a ministerial
capacity for the Company and the Underwriter, and its duties shall be determined
solely by the provisions hereof.  The Warrant Agent shall not, by issuing and
delivering Warrant Certificates or by any other act hereunder, be deemed to make
any representations as to the validity or value or authorization of the Warrant
Certificates or the Warrants represented thereby or of any securities or other
property delivered upon exercise of any Warrant or whether any stock issued upon
exercise of any Warrant is fully paid and non-assessable.

          (b)    The Warrant Agent shall not at any time be under any duty or
responsibility to any holder of Warrant Certificates to make or cause to be made
any adjustment of the Purchase Price provided in this Agreement, or to determine
whether any fact exists which may require any such adjustment, or with respect
to the nature or extent of any such adjustment, when made, or with respect to
the method employed in making the same.  It shall not (i) be liable for any
recital or statement of fact contained herein or for any action taken, suffered
or omitted by it in reliance on any Warrant Certificate or other document or
instrument believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties, (ii) be responsible for any failure on
the part of the

                                      25
<PAGE>
 
Company to comply with any of its covenants and obligations contained in this
Agreement or in any Warrant Certificate, or (iii) be liable for any act or
omission in connection with this Agreement except for its own gross negligence
or willful misconduct.

          (c)    The Warrant Agent may at any time consult with counsel
satisfactory to it (who may be counsel for the Company or the Underwriter) and
shall incur no liability or responsibility for any action taken, suffered or
omitted by it in good faith in accordance with the opinion or advice of such
counsel.
          (d)    Any notice, statement, instruction, request, direction, order
or demand of the Company shall be sufficiently evidenced by an instrument signed
by the Chairman of the Board of Directors, President or any Vice President
(unless other evidence in respect thereof is herein specifically prescribed).
The Warrant Agent shall not be liable for any action taken, suffered or omitted
by it in accordance with such notice, statement, instruction, request,
direction, order or demand.

          (e)    The Company agrees to pay the Warrant Agent reasonable
compensation for its services hereunder and to reimburse it for its reasonable
expenses hereunder; the Company further agrees to indemnify the Warrant Agent
and hold it harmless against any and all losses, expenses and liabilities,
including judgments, costs and counsel fees, for anything done or omitted by the
Warrant Agent in the execution of its duties and powers hereunder except losses,
expenses and liabilities arising as a result of the Warrant Agent's gross
negligence or willful misconduct.

          (f)    The Warrant Agent may resign its duties and be discharged from
all further duties and liabilities hereunder (except liabilities arising as a
result of the Warrant Agent's own gross negligence or willful misconduct), after
giving thirty (30) days' prior

                                      26
<PAGE>
 
written notice to the Company.  At least fifteen (15) days prior to the date
such resignation is to become effective, the Warrant Agent shall cause a copy of
such notice of resignation to be mailed to the Registered Holder of each Warrant
Certificate at the Company's expense.  Upon such resignation the Company shall
appoint in writing a new warrant agent.  If the Company shall fail to make such
appointment within a period of thirty (30) days after it has been notified in
writing of such resignation by the resigning Warrant Agent, then the Registered
Holder of any Warrant Certificate may apply to any court of competent
jurisdiction for the appointment of a new warrant agent.  Any new warrant agent,
whether appointed by the Company or by such a court, shall be a bank or trust
company having a capital and surplus, as shown by its last published report to
its stockholders, of not less than ten million dollars ($10,000,000) or a stock
transfer company doing business in New York, New York.  After acceptance in
writing of such appointment by the new warrant agent is received by the Company,
such new warrant agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named herein as the warrant agent,
without any further assurance, conveyance, act or deed; but if for any reason it
shall be necessary or expedient to execute and deliver any further assurance,
conveyance, act or deed, the same shall be done at the expense of the Company
and shall be legally and validly executed and delivered by the resigning Warrant
Agent.  Not later than the effective date of any such appointment, the Company
shall file notice thereof with the resigning Warrant Agent and shall forthwith
cause a copy of such notice to be mailed to the Registered Holder of each
Warrant Certificate.

          (g)    Any corporation into which the Warrant Agent or any new warrant
agent may be converted or merged, any corporation resulting from any
consolidation to

                                      27
<PAGE>
 
which the Warrant Agent or any new warrant agent shall be a party, or any
corporation succeeding to the corporate trust business of the Warrant Agent or
any new warrant agent shall be a successor warrant agent under this Agreement
without any further act, provided that such corporation is eligible for
appointment as successor to the Warrant Agent under the provisions of the
preceding paragraph.  Any such successor warrant agent shall promptly cause
notice of its succession as warrant agent to be mailed to the Company and to the
Registered Holders of each Warrant Certificate.

          (h)    The Warrant Agent, its subsidiaries and affiliates, and any of
its or their officers or directors, may buy and hold or sell Warrants or other
securities of the Company and otherwise deal with the Company in the same manner
and to the same extent and with like effect as though it were not Warrant Agent.
Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

          (i)    The Warrant Agent shall retain for a period of two (2) years
from the date of exercise any Warrant Certificate received by it upon such
exercise.

Price of any Warrant, other than such changes as are specifically set forth in

THIS CERTIFIES THAT, FOR VALUE RECEIVED

or registered assigns (the "Registered Holder") is the owner of the number of
Redeemable Warrants (the "Warrants") specified above.  Each Warrant initially
entitles the Registered Holder to purchase, subject to the terms and conditions
set forth in this Certificate and the Warrant Agreement (as hereinafter
defined), ____ fully paid and non-assessable shares of Common Stock, $.15 par
value per share, of Medical Device Technologies, Inc., a Utah corporation (the
"Company"), at any time from _____________, 1997 [thirteen (13) months after the
effective date of the Registration Statement] and prior to the Expiration Date
(as hereinafter defined) upon the presentation and surrender of this Warrant
Certificate with the Subscription Form on the reverse hereof duly executed, at
the corporate office of Continental Stock Transfer & Trust Company, 2 Broadway,
New York, New York 10004, as Warrant Agent, or its successor (the "Warrant
Agent"), accompanied by payment of $____ [150% of the conversion price of the
Preferred Stock], subject to adjustment (the "Purchase Price"), in lawful money
of the United States of America in cash or by check made payable to the Warrant
Agent for the account of the Company.

     This Warrant Certificate and each Warrant represented hereby are issued
pursuant to and are subject in all respects to the terms and conditions set
forth in the Warrant Agreement (the "Warrant Agreement"), dated __________, 1996
[the effective date of the Registration Statement], by and between the Company
and the Warrant Agent.

     In the event of certain contingencies provided for in the Warrant
Agreement, the Purchase Price and the number of shares of Common Stock subject
to purchase upon the exercise of each Warrant represented hereby are subject to
modification or adjustment.

     Each Warrant represented hereby is exercisable at the option of the
Registered Holder, but no fractional interests will be issued.  In the case of
the exercise of less than all  the Warrants represented hereby, the Company
shall cancel this Warrant Certificate upon the surrender hereof and shall
execute and deliver a new Warrant Certificate or Warrant

                                      A-1
<PAGE>
 
Certificates of like tenor, which the Warrant Agent shall countersign, for the
balance of such Warrants.

     The term "Expiration Date" shall mean 5:00 p.m. (New York time) on
__________, 1999 [the day before the 3rd anniversary of the effective date of
the Registration Statement].  If such date shall in the State of New York be a
holiday or a day on which banks are authorized to close, then the Expiration
Date shall mean 5:00 p.m. (New York time) the next following day which in the
State of New York is not a holiday or a day on which banks are authorized to
close.

     The Company shall not be obligated to deliver any securities pursuant to
the exercise of this Warrant unless a registration statement under the
Securities Act of 1933, as amended (the "Act"), with respect to such securities
is effective or an exemption thereunder is available.  The Company has
covenanted and agreed that it will file a registration statement under the
Federal securities laws, use its best efforts to cause the same to become
effective, to keep such registration statement current, if required under the
Act, while any of the Warrants are outstanding, and deliver a prospectus which
complies with Section 10(a)(3) of the Act to the Registered Holder exercising
this Warrant.  This Warrant shall not be exercisable by a Registered Holder in
any state where such exercise would be unlawful.

     This Warrant Certificate is exchangeable, upon the surrender hereof by the
Registered Holder at the corporate office of the Warrant Agent, for a new
Warrant Certificate or Warrant Certificates of like tenor representing an equal
aggregate number of Warrants, each of such new Warrant Certificates to represent
such number of Warrants as shall be designated by such Registered Holder at the
time of such surrender.  Upon due presentment and payment of any tax or other
charge imposed in connection therewith or incident thereto, for registration of
transfer of this Warrant Certificate at such office, a new Warrant Certificate
or Warrant Certificates representing an equal aggregate number of Warrants will
be issued to the transferee in exchange therefor, subject to the limitations
provided in the Warrant Agreement.

     Prior to the exercise of any Warrant represented hereby, the Registered
Holder shall not be entitled to any rights of a stockholder of the Company,
including, without limitation, the right to vote or to receive dividends or
other distributions, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided in the Warrant Agreement.

     Subject to the provisions of the Warrant Agreement, this Warrant may be
redeemed at the option of the Company, at a redemption price of $.05 per
Warrant, at any time commencing __________, 1997 [thirteen (13) months from the
effective date of the Registration Statement], provided that the closing bid
price for the Company's Common Stock, as reported by the National Association of
Securities Dealers Automated Quotation System (or, if not so quoted, as reported
by any other recognized quotation system on which the price of the Common Stock
is quoted), shall have, for any twenty (20) trading days within a period of
thirty (30) consecutive trading days ending on the tenth (10th) trading day
prior to the date on which the Notice of Redemption (as defined below) is given,
equalled or

                                      A-2
<PAGE>
 
exceeded $__________ [200% of the conversion price of the Preferred Stock] per
share (subject to adjustment in the event of any stock splits or other similar
events).  Notice of redemption (the "Notice of Redemption") shall be given not
later than the thirtieth (30th) day before the date fixed for redemption, all as
provided in the Warrant Agreement.  On and after the date fixed for redemption,
the Registered Holder shall have no rights with respect to this Warrant except
to receive the $.05 per Warrant upon surrender of this Certificate.

     Under certain circumstances, First Allied Securities, Inc., shall be
entitled to receive an aggregate of four percent of the Purchase Price of the
Warrants represented hereby.

     Prior to due presentment for registration of transfer hereof, the Company
and the Warrant Agent may deem and treat the Registered Holder as the absolute
owner hereof and of each Warrant represented hereby (notwithstanding any
notations of ownership or writing hereon made by anyone other than a duly
authorized officer of the Company or the Warrant Agent) for all purposes and
shall not be affected by any notice to the contrary, except as provided in the
Warrant Agreement.
