Item 5.  Other Events.
         ------------ 

     On April 8, 1998, AgriBioTech, Inc., a Nevada corporation (the
"Registrant"), completed the acquisition from John J. Zajac, Ellen M. Zajac and
Sandra P. Zajac-Pepin (the "Sellers") of (i) 100% of the issued and outstanding
shares of common stock (the "Stock") of Zajac Performance Seeds, Inc., a New
Jersey corporation ("Zajac New Jersey"), pursuant to the terms of a Stock
Purchase Agreement among the Sellers, the Registrant and Zajac New Jersey;  and
(ii) all of the membership interests (the "Membership Interests"), of Zajac
Performance Seeds Oregon, L.L.C., an Oregon limited liability company ("Zajac
Oregon") pursuant to the terms of a Securities Purchase Agreement among the
Sellers, the Registrant and Zajac Oregon.

     The aggregate purchase price was $6,600,000, of which $3,600,000 was
attributed to the purchase of the Membership Interests in Zajac Oregon and was
paid in cash and $3,000,000 of which was attributed to the purchase of the Stock
of Zajac New Jersey and was paid in 300,000 shares of the Registrant's Common
Stock, which, at the time the terms were agreed upon, was valued at $10.00 per
share. The parties agreed that the effective date of the acquisition for
accounting purposes, shall be prior to the opening of business on January 1,
1998.

     At the Closing, each of the Sellers entered into an Employment Agreement
with the Registrant.  The term of employment under the Employment Agreements is
three years for John J. Zajac and Sandra Zajac-Pepin, and one year for Ellen M.
Zajac.  Each of the Sellers also entered into a Non-Competition Agreement with
the Registrant for which John J. Zajac received $200,000, Sandra Zajac-Pepin
received $100,000, and Ellen M. Zajac received $50,000 in cash as consideration
for the non-compete provisions in such agreements. The term of each of the Non-
Compete Agreements commenced on the Closing Date and  continues for a period of
three years following termination of each Seller's respective employment with

<PAGE>
 
              not include or omit to state any fact which renders the Financials
              misleading.

         (ii) Except as and to the extent shown or provided for in the
              Financials or the notes and schedules thereto or as disclosed in
              any of the Schedules to this Agreement or such current liabilities
              as may have been incurred since December 31, 1997 in the ordinary
              course of business, the Acquired Company has no liabilities or
              obligations (whether accrued, absolute, contingent or otherwise)
              which might be or become a charge against the assets or
              liabilities of the Acquired Company; as of December 31, 1997,
              there was no asset used by the Acquired Company in its operations
              that has not been reflected in the Financials, and, except as set
              forth in the Financials, no assets have been acquired by the

              and any other entity in which any of the Sellers is an officer,
              director or has an equity interest have been at prices no less
              favorable to the Acquired Company than could have been obtained
              from any independent third party.

      (h) Absence of Certain Changes.  Except as disclosed on SCHEDULE 4(H),
          --------------------------

condition (financial or otherwise), operations, assets, liabilities, earnings,
business, prospects or results of operations of the Acquired Company.

      (i) Tax Matters.
          ----------- 

          Zajac has had in effect, for at least the past three (3) years, an
election under Subchapter S of the Internal Revenue Code.  Zajac has timely
filed all federal, state and local income tax returns and has timely filed with
all other appropriate governmental agencies all sales, ad valorem, franchise and
other tax, license, gross receipts and other similar returns and reports
required to be filed by it.  The Acquired Company has reported all taxable
income and losses on those returns on which such information is required to be
reported, and paid or provided for the payment of all

                                       7
<PAGE>
 
taxes due and payable on said returns or taxes due pursuant to any assessment
received by it, including without limitation, any taxes required by law to be
withheld and/or paid in connection with any officer's or employee's compensation
or due pursuant to any assessment received by it. There are no agreements for
the extension of time for the assessment or payment of any amounts of tax. The
Sellers have made available to the Buyer for inspection copies of income tax
returns that are true and complete copies of the federal and applicable state,
local or other income tax returns filed by the Acquired Company for the taxable
years ended December 31, 1994, 1995, and 1996, and any other open tax periods.
The Acquired Company shall bear all expenses and responsibilities for the filing
of federal and applicable state, local or other income tax returns and reports
of the Acquired Company for the taxable year ended December 31, 1997, but the
Buyer and the Acquired Company hereby covenant and agree that the Acquired
Company will not file any amended income tax returns for any period prior to
January 1, 1998 without first notifying the Sellers. All tax liabilities of the
Acquired Company arising through the end of the taxable year ended December 31,
1997 have been paid. All tax liabilities of the Acquired Company arising after
December 31, 1997 have been paid or adequately disclosed and properly reserved
for on the books and records and financial statements of the Acquired Company.
Sellers are responsible for the payment of all taxes for all periods through
December 31, 1997. No federal or applicable state, local or other tax return of
the Sellers or the Acquired Company for any period has been or is currently
under audit by the Internal Revenue Service or any state, local or other tax
authorities. No claim has been made by federal, state, local or other
authorities relating to any such returns or any audit. For purposes of this
Section 4(i), the word "timely" shall mean that such returns were filed within
the time prescribed by law for the filing thereof, including the time permitted
under any applicable extensions. The Sellers and the Acquired Company are not
aware of any facts which they believe would constitute the basis for the
proposal of any tax deficiencies for any unexamined year. All taxes which the
Acquired Company is required by law to withhold and collect have been duly
withheld and collected, and have been timely paid over to the proper authorities
to the extent due and payable.

              Company reflected in the Financials as at December 31, 1997, and
              the accounts receivable acquired by the Acquired Company since
              such date are valid subsisting claims for the aggregate amounts
              thereof reflected in the Financials net of the reserves or
              allowances for doubtful receivables reflected in the Financials or
              thereafter in the Acquired Company's books and records uniformly
              maintained in accordance with the financial statements, accounted
              for in accordance with generally accepted accounting principles,
              and the Sellers know of no reason that would make such accounts
              receivable, net of such amounts as the Acquired Company has
              reserved on its books as of December 31, 1997, taken as a whole,
              not collectible.

aware of or has received notice of, the violation of any applicable zoning
regulation, ordinance or other law, order, regulation or requirement in force on
the date hereof relating to the Acquired Company's business or its owned or
leased real or personal properties, with which it has not complied.

          Before Closing, the Buyer may engage consultants or engineers of the
Buyer's choosing to conduct site studies of the real property as the Buyer deems
necessary.  The Buyer or its agents shall have the right to enter the real
property at reasonable times before closing to make such tests, inspections,
studies, and other investigations as the Buyer may require, at the Buyer's
expense and risk.  The Buyer shall indemnify and hold the Sellers harmless from
any loss, damage, or claim arising out of the Buyer's access to the real
property for the purpose of making tests, inspections, studies, and other

<PAGE>
 
              (C) there is no disqualified benefit (as such term is defined in
                  Code Section 4976(b)) which would subject the Acquired Company
                  or the Buyer to a tax under Code Section 4976(a);

              (D) each such Welfare Plan which is a group health plan complies
                  and has complied with the applicable requirements of Code
                  Section 4980B, and would comply with Sections 9801 through
                  9806 if such provisions were now in effect, Title XXII of the
                  Public Health Service Act, and the applicable provisions of
                  the Social Security Act, and is not and has not been a
                  nonconforming group health plan under Section 5000(c) of the
                  Code;

              (E) each such Welfare Plan may be amended or terminated by the
                  Acquired Company or the Buyer, on or at anytime after the
                  Closing Date and after any advance notice to participants or
                  similar measures required by law which are non-waivable under
                  the Welfare Plan;

              (F) no such Welfare Plan provides for continuing benefits or
                  coverage for any participant (including past, present or
                  future retirees) or such participant's beneficiary after
                  termination of employment except as required by the
                  Consolidated Omnibus Reconciliation Act of 1985 ("COBRA") or
                  any other state or Federal law; and

              (G) no claims have been made and no other events have occurred
                  that might form the basis of a claim which has substantially
                  increased or, based on customary insurance industry practice,

              placed any "Hazardous Material" on or under the real property
              owned or leased by the Acquired Company and, to the best of
              Sellers' knowledge, there has been no "Hazardous Material" on or

              knowledge and belief of the Sellers, any officer, employee or

              person acting on its behalf, has, directly or indirectly, within
              the past three (3) years given or received or agreed to give or

      (d) Defense of Claims.  Whenever any Claim shall arise for indemnification
          -----------------                                                     
hereunder, the party entitled to indemnification (the "Indemnitee") shall notify
the indemnifying party (the "Indemnitor") in writing within 30 days after the
Indemnitee has actual knowledge that it is entitled to indemnification of such
Claim constituting the basis for such Claim (the "Notice of Claim").  The Notice
of Claim shall specify all facts known to the Indemnitee giving rise to such
indemnification claim and the amount or an estimate of the amount of the
liability arising therefrom.

          If the facts giving rise to any such indemnification shall involve any
actual, threatened or possible claim or demand by any person against the
Indemnitee, the Indemnitor shall be entitled (without prejudice to the right of
the Indemnitee to participate at its expense through co-counsel of its own
choosing) to contest or defend such claim at his expense and through counsel of
his own choosing if he gives written notice of his intention to do so to the
Indemnitee within 10 days after receipt of the Notice of Claim; provided that
Indemnitor diligently prosecutes or defends such claim.

          The Indemnitee shall not settle any claim which would give rise to
liability on the part of the Indemnitor under the indemnity contained in this
Section without the written consent of the Indemnitor, which consent shall not
unreasonably be withheld.  If a firm offer is made to settle a claim or
litigation defended by the Indemnitee and the Indemnitor refuses to accept such
offer within 20 days after receipt of written notice from the Indemnitee of the
terms of such offer, then, in such event, the Indemnitee shall continue to
contest or defend such claim and shall be indemnified pursuant to the terms
hereof.  Provided, however, that in the event the Indemnitor refuses to accept
such offer to settle a claim as described above and the Indemnitee continues to
contest or defend such claim, the indemnification provided for herein shall be
deemed to include the value of management's time spent in connection with the
defense of such claim.  If a firm offer is made to settle a claim or litigation
and the Indemnitor notifies the Indemnitee in writing that the Indemnitor
desires to accept and agree to such settlement, but the Indemnitee elects not to
accept or agree to it, the Indemnitee may continue to contest or defend such
claim or litigation and, in such event, the total maximum liability of the
Indemnitor to indemnify or otherwise reimburse the Indemnitee hereunder with
respect to such claim or litigation shall be limited to and shall not exceed the
amount of such settlement offer, plus reasonable out-of-pocket costs and
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnitor desires to accept such settlement.

          Notwithstanding any provision of this Agreement to the contrary, no
claim for indemnification pursuant to this Section 6, by the Indemnitee shall be
asserted or claimed except to the extent any Claim exceeds, in the aggregate,
the sum of $10,000.

          Notwithstanding any provision of this Agreement to the contrary,
neither Sellers' nor Buyer's maximum liability for indemnification shall exceed
the Purchase Price.

              for the periods ended December 31, 1994, 1995, and 1996, together
              with the related notes and schedules, and the financial statements
              of the corporation as of and for the period ended December 31,
              1997, together with the related notes and schedules (collectively,
              the "Financials"), true, correct and complete copies of which are
              attached hereto as SCHEDULE 4(G), (A) are in accordance with the
              books of account and records of the Corporation; (B) present
              fairly, and are true, correct and complete statements of the
              financial condition and the results of operations of the Acquired
              Company as at and for the periods therein specified; and (C) do
              not include or omit to state any fact which renders the Financials
              misleading.

         (ii) Except as and to the extent shown or provided for in the
              Financials or the notes and schedules thereto or as disclosed in
              any of the Schedules to this Agreement or such current liabilities
              as may have been incurred since December 31, 1997 in the ordinary
              course of business, the Acquired Company has no liabilities or
              obligations (whether accrued, absolute, contingent or otherwise)
              which might be or become a charge against the assets or
              liabilities of the Acquired Company; as of December 31, 1997,
              there was no asset used by the Acquired Company in its operations
              that has not been reflected in the Financials, and, except as set
              forth in the Financials, no assets have been acquired by the
              Acquired Company since such date except in the ordinary course of
              business.

              in members' equity in Zajac as compared with the amount shown for
              such members' equity as at December 31, 1997, and no material
              adverse changes in the financial position of the Acquired Company
              since December 31, 1997.

         (iv) The Financials do not include any assets, liabilities, income or
              expenses of any entity other than the Acquired Company. All
              transactions in the years 1995-1997 between the Acquired Company
              and any other entity in which any of the Sellers is an officer,
              director or has an equity interest have been at prices no less
              favorable to the Acquired Company than could have been obtained
              from any independent third party.

      (h) Absence of Certain Changes.  Except as disclosed on SCHEDULE 4(H),
          --------------------------                                        
since December 31, 1997, there has not been any material adverse change in the
condition (financial or otherwise), operations, assets, liabilities, earnings,
business, prospects or results of operations of the Acquired Company.

      (i) Tax Matters.
          ----------- 

          The Acquired Company has timely filed all federal, state and local
income tax returns and has timely filed with all other appropriate governmental
agencies all sales, ad valorem, franchise and other tax, license, gross receipts
and other similar returns and reports required to be filed by it. The Acquired
Company has reported all taxable income and losses on those returns on which
such information is required to be reported, and paid or provided for the
payment of all taxes due and payable on said returns or taxes due pursuant to
any assessment received by it, including without limitation, any taxes required
by law to be withheld and/or paid in connection with any officer's or employee's
compensation or due pursuant to any assessment received by it.  There are no
agreements for the extension of time for the assessment or payment of any
amounts of tax.  The Sellers have made available to the Buyer for inspection
copies of income tax returns that are true and complete copies of the federal
and applicable state, local or other income tax returns filed by the Acquired
Company for the taxable years ended December 31, 1994, 1995, and 1996, and any
other open tax periods.  The Acquired Company shall bear all expenses and
responsibilities for the filing of federal and applicable state, local or other
income tax returns and reports of the Acquired Company for the taxable year
ended December 31, 1997, but the Buyer and the Acquired Company hereby covenant
and agree that the Acquired Company will not file any  amended income tax
returns for any period prior to January 1, 1998 without first notifying the
Sellers.  All tax liabilities of the Acquired Company arising through the end of
the taxable year ended December 31, 1997 have been paid.  All tax liabilities of
the Acquired Company arising after December 31, 1997 have been paid or
adequately disclosed and properly reserved for on the books and records and
financial statements of the Acquired Company.  Sellers are responsible for the
payment of all taxes for all periods through December 31, 1997.  No federal or
applicable state, local or other tax return of the Sellers or the Acquiring
Company  for any period has been or is currently under audit by the Internal
Revenue Service or any state, local or other tax authorities.  No claim has been
made by federal, state, local or other authorities relating to any such returns
or any audit.  For purposes of this Section 4(i), the word "timely" shall mean
that such returns were filed within the time prescribed by law for the filing
thereof, including the time permitted under any applicable extensions.  The
Sellers and the Acquired Company are not aware of any facts which they believe
would constitute the basis for the proposal of any tax deficiencies for any
unexamined year.  All taxes which the Acquired Company is required by law to
withhold and collect have been duly withheld and collected, and have been timely
paid over to the proper authorities to the extent due and payable.

              accordance with the financial statements, accounted for in
              accordance with generally accepted accounting principles, and the
              Sellers know of no reason that would make such accounts
              receivable, net of such amounts as the Acquired Company has
              reserved on its books as of December 31, 1997, taken as a whole,
              not collectible.

              marketable or adequate provision for obsolescence has been

              reserved on its books as of December 31, 1997, taken as a whole,
              not marketable.

      (k) Title and Condition of Properties.  The Acquired Company does not own
          ---------------------------------                                    
any real property, except as disclosed on SCHEDULE 4(K).  Except as disclosed on
SCHEDULE 4(K), the Acquired Company has good and marketable title to all
properties and assets, real and personal, tangible and intangible, reflected in
the Financials and all properties acquired subsequent to December 31, 1997,
which have not been disposed of in the ordinary course of business since
December 31, 1997, which property is subject to no mortgage, lien, deed of

Company is in operating condition and, subject to routine maintenance and
ordinary wear and tear, has been maintained in accordance with reasonable
industry standards and is suitable for the purpose for which it is used.  Except
as disclosed in SCHEDULE 4(K), neither the Sellers nor the Acquired Company is
aware of or has received notice of, the violation of any applicable zoning
regulation, ordinance or other law, order, regulation or requirement in force on
the date hereof relating to the Acquired Company's business or its owned or
leased real or personal properties, with which it has not complied.

          At Closing, the Sellers shall provide, at their expense, a standard
owner's title insurance policy in the amount of the Purchase Price allocated to
the real property and improvements, which Buyer shall acquire from Sellers,
insuring title vested in the Buyer or its nominees, subject only to
nondelinquent real property taxes and those exceptions set forth on the
preliminary title report which according to Buyer are acceptable and do not
render title unmarketable or uninsurable.

          Before Closing, the Buyer may engage consultants or engineers of the
Buyer's choosing to conduct site studies of the real property as the Buyer deems
necessary.  The Buyer or its agents shall have the right to enter the real
property at reasonable times before closing to make such tests, inspections,
studies, and other investigations as the Buyer may require, at the Buyer's
expense and risk.  The Buyer shall indemnify and hold the Sellers harmless from
any loss, damage, or claim arising out of the Buyer's access to the real
property for the purpose of making tests, inspections, studies, and other
investigations.  It shall be a condition to closing that the results of such
studies or analyses be acceptable to the Buyer in its sole discretion.

SCHEDULE 4(L), all parties to, or otherwise bound by, such agreements,
contracts, commitments, obligations and undertakings have performed all
obligations required to be performed by them to date and the Acquired Company is
not in default and no event, occurrence, condition or act exists which gives

default or right of cancellation, acceleration or loss of contractual benefits
under, any such contract, agreement, commitment, obligation or undertaking.
There has been no threatened cancellations thereof, and there are no outstanding
disputes under any such contract, agreement, commitment, obligation or
undertaking. Except as set forth in SCHEDULE 4(1), no consent of any party is

and will constitute a valid and binding obligation of the respective parties to
such agreements, and there is not, under any such contract, lease, instrument or
commitment, any existing default by any of the parties or any event that, with
notice, lapse of time or both, would constitute a default by any of the parties
in respect of which adequate steps have not been taken to cure such default or
to prevent a default from occurring or continuing.  Any contracts, leases or
commitments held in the names of any of the Sellers and listed on the Schedules
shall be assigned either to the Buyer or the Acquired Company prior to the
Closing Date.

          No agreement, contract, commitment, obligation or undertaking listed
on the Schedules hereto to which the Acquired Company is a party or by which it
or any of its properties is bound, except as specifically set forth in SCHEDULE
4(L), contains any provision which materially adversely affects or in the future
may (so far as the Sellers and the Acquired Company can reasonably now foresee)
materially adversely affect the condition, properties, assets,  liabilities,
business, operations or prospects of the Acquired Company following the date
hereof and upon the Closing Date.  Furthermore, to the best of the Sellers'
knowledge, the material suppliers, customers and clients of the Acquired Company
will continue to supply and purchase from the Acquired Company after the

              Corporation or to the participants in such plan or to the
              beneficiaries of such participants. Each such terminated plan was
              terminated substantially in accordance with the applicable
              provisions of law or any agreement or contract relating to any

              Acquired Company that is an employee welfare benefit plan, whether

              Plan"), the following is true:

              (A) each such Welfare Plan intended to meet the requirements for
                  tax-favored treatment under Subchapter B of Chapter 1 of the
                  Code meets such requirements;

              (B) there is no voluntary employees' beneficiary association
                  (within the meaning of Section 501(c)(9) of the Code)
                  maintained with respect to any such Welfare Plan;

              (C) there is no disqualified benefit (as such term is defined in
                  Code Section 4976(b)) which would subject the Acquired Company
                  or the Buyer to a tax under Code Section 4976(a);

              (D) each such Welfare Plan which is a group health plan complies
                  and has complied with the applicable requirements of Code
                  Section 4980B, and would comply with Sections 9801 through
                  9806 if such provisions were now in effect, Title XXII of the
                  Public Health Service Act, and the applicable provisions of
                  the Social Security Act, and is not and has not been a
                  nonconforming group health plan under Section 5000(c) of the
                  Code;

              (E) each such Welfare Plan may be amended or terminated by the
                  Acquired Company or the Buyer, on or at anytime after the
                  Closing Date and after any advance notice to participants or
                  similar measures required by law which are non-waivable under
                  the Welfare Plan;

              (F) no such Welfare Plan provides for continuing benefits or
                  coverage for any participant (including past, present or
                  future retirees) or such participant's beneficiary after
                  termination of employment except as required by the
                  Consolidated Omnibus Reconciliation Act of 1985 ("COBRA") or

              (G) no claims have been made and no other events have occurred
                  that might form the basis of a claim which has substantially
                  increased or, based on customary insurance industry practice,
                  might substantially increase the premiums or other charges of
                  the Acquired Company under any Welfare Plan.

         ---------

              injunctions (collectively, the "Laws"), as in effect on or before

              Laws relating to seed labeling and all rules and regulations of
              the Occupational Safety and Health Administration. Neither the

              received notice or communication from any third party asserting a
              failure to comply with any Laws, nor has the Acquired Company
              received any notice that any authority or third party intends to

              under the Comprehensive Environmental Response, Compensation and
              Liabilities Act ("CERCLA"), any so-called "Super Fund" or "Super
              Lien" law or any other applicable federal, state or local statute,
              law, ordinance, code, rule, regulation, order or decree now or at
              any time hereafter in effect, regulating, relating to or imposing
              liability or standards of conduct concerning any Hazardous
              Material.

        (iii) Since the date first acquired or leased by the Sellers or the
              Acquired Company, none of the Sellers nor the Acquired Company has
              placed any "Hazardous Material" on or under the real property
              owned or leased by the Acquired Company and, to the best of
              Sellers' knowledge, there has been no "Hazardous Material" on or

              used in compliance with all Environmental Laws, (b) standard
              office supplies in commercially reasonably amounts required for
              use in the ordinary course of business, provided such items are

              knowledge and belief of the Sellers, any officer, employee or
              agent of the Acquired Company

                                      15

              criminal or governmental litigation or proceeding, (ii) if not
              given or received in the past might have had an adverse effect on
              the assets, business or operation of such Acquired Company, or

              assets, the business or the operations or prospects of such
              Acquired Company, or which might subject such Acquired Company to

      (a) Survival of Representations and Warranties.   All representations and
          ------------------------------------------                           
warranties made by the Sellers or the Buyer in this Agreement, including without
limitation all representations and warranties made in any Exhibit or Schedule

that all representations and warranties made by the Sellers in Sections 4(i),

after the expiration of the applicable statute of limitations (the "Extended
Survival Date").

      (b) Indemnity by Sellers.  Provided that the transaction contemplated by
          --------------------                                                
this Agreement is closed, the Sellers hereby agree to indemnify, defend and hold
harmless the Buyer from and against all liabilities, losses, costs or damages
whatsoever (including expenses and reasonable fees of legal counsel) ("Claims")
arising out of or relating to Claims made prior to the Survival Date or the
Extended Survival Date, if applicable, in the event that it is determined that
such Claims arise out of or from or are based upon (i) the inaccuracy in any
material respect of any  representation or warranty contained in Section 4 made
by the Sellers;  (ii) the non-performance by the Sellers in any material respect
of any covenant, agreement or obligation to be performed by the Sellers under
this Agreement; or (iii) the assessment of any federal, state local or other tax
liabilities due and payable by the  Acquired Company for all periods prior to
January 1, 1998.

      (c) Indemnification by Buyer.  Provided that the transaction contemplated
          ------------------------                                             
by this Agreement is closed, the Buyer hereby agrees to indemnify, defend and
hold harmless the Sellers from and against all Claims arising out of or from or
based upon (i) the inaccuracy in any material respect of any representation or
warranty contained in Section 5 by the Buyer; (ii) the non-performance by the
Buyer in any material respect of any covenant, agreement or obligation to be
performed by the Buyer under this Agreement; and (iii) any liabilities arising
out of the operation of the business of the  Acquired Company by Buyer after the
Closing Date.

          In the event that the Closing is consummated, the Buyers agree to
indemnify Sellers against all costs and expenses with respect to their state and
federal income tax liability for income tax items allocated to them as members
of Zajac Oregon with respect to the period January 1, 1998 through the Closing
Date.

      (d) Defense of Claims.  Whenever any Claim shall arise for indemnification
          -----------------                                                     
hereunder, the party entitled to indemnification (the "Indemnitee") shall notify
the indemnifying party (the

                                      18
<PAGE>
 
"Indemnitor") in writing within 30 days after the Indemnitee has actual
knowledge that it is entitled to indemnification of such Claim constituting the
basis for such Claim (the "Notice of Claim"). The Notice of Claim shall specify
all facts known to the Indemnitee giving rise to such indemnification claim and
the amount or an estimate of the amount of the liability arising therefrom.

          If the facts giving rise to any such indemnification shall involve any
actual, threatened or possible claim or demand by any person against the
Indemnitee, the Indemnitor shall be entitled (without prejudice to the right of
the Indemnitee to participate at its expense through co-counsel of its own
choosing) to contest or defend such claim at his expense and through counsel of
his own choosing if he gives written notice of his intention to do so to the
Indemnitee within 10 days after receipt of the Notice of Claim; provided that
Indemnitor diligently prosecutes or defends such claim.

          The Indemnitee shall not settle any claim which would give rise to
liability on the part of the Indemnitor under the indemnity contained in this
Section without the written consent of the Indemnitor, which consent shall not
unreasonably be withheld.  If a firm offer is made to settle a claim or
litigation defended by the Indemnitee and the Indemnitor refuses to accept such
offer within 20 days after receipt of written notice from the Indemnitee of the
terms of such offer, then, in such event, the Indemnitee shall continue to
contest or defend such claim and shall be indemnified pursuant to the terms
hereof.  Provided, however, that in the event the Indemnitor refuses to accept
such offer to settle a claim as described above and the Indemnitee continues to
contest or defend such claim, the indemnification provided for herein shall be
deemed to include the value of management's time spent in connection with the
defense of such claim.  If a firm offer is made to settle a claim or litigation
and the Indemnitor notifies the Indemnitee in writing that the Indemnitor
desires to accept and agree to such settlement, but the Indemnitee elects not to
accept or agree to it, the Indemnitee may continue to contest or defend such
claim or litigation and, in such event, the total maximum liability of the
Indemnitor to indemnify or otherwise reimburse the Indemnitee hereunder with
respect to such claim or litigation shall be limited to and shall not exceed the
amount of such settlement offer, plus reasonable out-of-pocket costs and
expenses (including reasonable attorneys' fees and disbursements) to the date of
notice that the Indemnitor desires to accept such settlement.

          Notwithstanding any provision of this Agreement to the contrary, no
claim for indemnification pursuant to this Section 6, by the Indemnitee shall be
asserted or claimed except to the extent any Claim exceeds, in the aggregate,
the sum of $10,000.

          Notwithstanding any provision of this Agreement to the contrary,
neither Sellers' nor Buyer's maximum liability for indemnification shall exceed
the Purchase Price.

          ------------                                                         
informal meetings and discussions, the dispute shall be settled by binding
arbitration, and a corresponding judgment may be entered in a court of competent
jurisdiction.  Arbitration of any dispute may be initiated by one party by
sending a written demand for arbitration to the other party, which demand will
preclude any party hereto from initiating an action in any court.  This demand
will specify the matter in dispute and request the appointment of an arbitration
panel.  The arbitration panel will consist of one arbitrator named by Buyer, one
arbitrator named by Sellers and a third arbitrator named by the two arbitrators
so chosen.  The arbitration hearing will be conducted in accordance with the
procedural rules set forth in the commercial arbitration rules of the American
Arbitration Association.  The situs of the arbitration will be New York, New
York.  The arbitrators shall not be empowered to award punitive or exemplary
damages to either party.

      (b) Consent to Jurisdiction; Waiver of Jury Trial.  In the event that
          ---------------------------------------------                    
litigation of a dispute is initiated by either of the parties hereto, each of
the parties hereto (i) consents to submit itself to the personal jurisdiction of
the Courts of the State of Nevada or the United States District Court for the
District of Nevada to the extent that such court would have subject matter
jurisdiction with respect to such dispute; (ii) agrees that it will not attempt
to deny or defeat such personal jurisdiction or venue by motion or other request
for leave from any such court; (iii) agrees that it will not bring any action
relating to this Agreement or any of the transactions contemplated by this
Agreement in any Court other than such courts; (iv) agrees that service of
process in any such action or proceeding may be effected by mailing a copy
thereof by registered or certified mail (or any substantially similar form of
mail), postage prepaid, to a party at its address set forth in Section 22 or at
such other address of which a party shall have been notified pursuant thereto;
(v) agrees that nothing herein shall affect the right to effect service of
process in any other manner permitted by law; and (vi) waives the right to a
jury trial.

  SECTION 21.  SEVERABILITY.  If any part of this Agreement is held to be
               ------------                                              
unenforceable or invalid under, or in conflict with, the applicable law of any
jurisdiction, the unenforceable, invalid or

                                      26
<PAGE>
 
conflicting part shall, to the extent permitted by applicable law, be narrowed
or replaced, to the extent possible, with a judicial construction in such
jurisdiction that effectuates the intent of the parties regarding this Agreement
and such unenforceable, invalid or conflicting part. To the extent permitted by
applicable law, notwithstanding the unenforceability, invalidity or conflict
with applicable law of any part of this Agreement, the remaining parts shall be
valid, enforceable and binding on the parties.
