ITEM 5.  OTHER EVENTS

On July 9, 1997, Biomune Systems, Inc. (the "Company" or the "Registrant") 
entered into an agreement by which it purchased an option to acquire all of 
the issued and outstanding shares of the capital stock of Rockwood 
Investments, Inc., a California corporation doing business as Rockwood 
Investments, Inc. ("Rockwood").  Under the terms of the option agreement, 
which has a maximum term of 12 months, the Company may acquire the shares of 
Rockwood for $5,000,000 cash.  The cost of the option is $105,000 per quarter 
(or an aggregate of $420,000).  All option fees paid through the date of the 
exercise of the option will be credited to the purchase price of the Rockwood 
shares.  The full terms of the transaction are set forth in a written 
agreement which is filed with this report as an exhibit and which is 
incorporated herein by this reference.  This summary is qualified in its 
entirety by the written agreement.

In addition to the option agreement, the Company entered into a consulting 
agreement with Andela Group, Inc., a California corporation ("Andela"), for 
consulting services to be provided through Ira E. Ritter, age 48, the sole
shareholder of Andela and Rockwood ("Ritter").  Under the consulting agreement,
Ritter was named President of Biomune effective July 9, 1997.  Andela will
receive a monthly consulting fee of $15,000 during the one-year term of the
consulting agreement.  If the option is exercised by the Company and Rockwood
is acquired, Ritter will become an employee of the Company at an annual salary
of $200,000 and will receive annual bonus and other incentive payments based on
a percentage of the increase in net sales, as well as options to acquire 
3,000,000 shares of the Company's common stock at a price of $.40 per share.

On July 17, 1997, the Company issued the following press release in connection 
with this transaction:

Salt Lake City, Utah: July 17, 1997 -- Biomune Systems, Inc. (NASDAQ: BIME) 
today announced the appointment of its new President, Ira E. Ritter.  Mr. 
Ritter has an extensive history of building successful companies.  During the 
1970's and 1980's, Mr. Ritter built a publishing empire from inception to 
having in excess of $50 million per year in sales before selling his company 
to a Fortune 100 company.  Most recently, Mr. Ritter was Vice Chairman of a 
national food and cosmetic distributor, where he assisted in building sales in 
excess of $1 billion per year.  Mr. Ritter has proven to be successful in 
marketing and distributing products similar to those produced by Biomune.

In a transaction related to becoming President of Biomune, the company 
acquired the right to purchase Mr. Ritters [sic] controlling interest in 
Rockwood, Inc. [sic] a multimillion dollar sales company that distributes over 
100 products to health food stores nationwide.
Mr. David Derrick who had been acting as interim president for the past three 
months will remain on as Chairman and CEO of Biomune, was pleased to have a 
businessman of Mr. Ritter's caliber and commitment join the Company's 
management team.  "Ira's marketing expertise, distribution contacts and savvy, 
coupled with the Company's immune enhancing products, should add to the high 
expectations for the future growth and success of Biomune."

This press release contains certain forward-looking statements about the 
Company's goals and anticipated future performance.  The industry in which the 
Company proposes to operate is dynamic and intensely competitive, and there 
are many factors that could cause the forward-looking statements contained 
herein not to occur or the timing of their occurrence to be delayed.  With the 
exception of historical information, the matters discussed in this press 
release are forward-looking statements that involve substantial risks and 
uncertainties, including but not limited to, the results of ongoing 
nutritional studies, economic conditions, product and technology development, 
production efficiencies, product demand, competitive products and the 
competitive environment, availability of raw materials and critical 
manufacturing equipment and facilities and other risks identified in filings 
made with the Securities and Exchange Commission.

               (i)     a certificate executed by Sellers representing and 
warranting to Biomune that subject to the exceptions set forth in the

Agreement are true and correct in all material respects as of the Second

          (c)     Biomune shall cause to be prepared audited financial 
statements for Rockwood for the fiscal years ended March 31, 1995, 1996 and 
1997, and, if the Second Closing Date occurs after May 15, 1998, for the 
fiscal year ending March 31, 1998 (collectively, the "Audits" and each an 
"Audit").

          (d)     The Exercise Price payable by Biomune upon exercise of the 
Option on the Second Closing Date is subject to adjustment as follows:

               (i)     if the Audit for the fiscal year ending March 31, 1998 
discloses gross revenues for Rockwood for the period covered by such statement 
are less than $4,000,000, then the Exercise Price shall be reduced by an 
amount equal to the difference between $4,000,000 and the actual gross 
revenues for the period within the applicable audited financial statements.  
If the Second Closing Date occurs prior to May 15, 1998 and the Interim 
Statements reflect gross revenues which would, on an annualized basis, be less 
than $4,000,000, then the parties shall select a national bank having branch 
offices in Los Angeles, California as an escrow agent (the "Escrow Agent"), 
and Biomune shall deposit with the Escrow Agent the difference between the 
annualized revenues of Rockwood shown on the Interim Statements and $4,000,000 
(the "Escrowed Amount"), and deduct the Escrowed Amount from the funds paid to 
Ritter on the Second Closing Date.  On or about May 16, 1998, upon completion 
of the Audit, the Escrow Agent shall disburse the Escrowed Amount to Biomune 
and/or Ritter based on the final Exercise Price as determined from the actual 
gross revenues of Rockwood as shown on within the audited financial statements 
for the fiscal year ending March 31, 1998.  If the Escrowed Amount is 
insufficient to cover the adjustment to the Exercise Price based on the Audit, 
or if no Escrow was required based on the Interim Statements, Ritter shall 
promptly after completion of the Audit, reimburse the remainder of the 
adjustment to Biomune.  Biomune shall conduct the Business of Rockwood in good 
faith and consistent with reasonable commercial practices after the Second 
Closing Date and prior to March 31, 1998 and Ritter shall be President of 
Biomune during such time, consistent with the terms of the Employment 
Agreement, or the final Exercise Price shall be deemed to be $5,000,000 
without adjustment in respect of gross revenues;

               (ii)     if the Second Closing Date occurs after September 30, 
1997, then the Exercise Price shall be increased at an annualized rate of five 
percent (5%) from October 1, 1997 through the Second Closing Date;

               (iii)    all amounts paid as the Option Price prior to the 
Second Closing Date shall be offset as a credit against the Exercise Price and 
reduce the amount payable at the Second Closing; and

               (iv)     to the extent the liabilities of Rockwood exceed the 
value of certain of its assets as provided in Section 6.6, below, then such 
excess liabilities shall reduce the Exercise Price as provided in such Section 
6.6.

     2.6.     EFFECT OF TERMINATION; RESCISSION. 

          (a)     In the event Biomune terminates the Option at any time as 
provided in Section 2.2(b)(ii), Biomune shall have no recourse against Ritter 
other than the return of the Option Price from the date of occurrence of such 
Breach.  Upon termination of the Option under such circumstances, this 
Agreement shall terminate and no party hereto shall have any further 
obligation to the other, except for obligations under collateral or separate 
agreements that may continue in force thereafter, including, without 
limitation, the Consulting Agreement.

          (b)     Upon termination by Ritter under Section 2.2(a) or by 
Biomune under Section 2.2(b)(i), all amounts paid prior to the date of such 
termination by Biomune shall be retained by Ritter and any payments in respect 
of the Option then due but not made shall be made promptly by Biomune.  Upon 
termination of the Option under such circumstances, this Agreement shall 
terminate and no party hereto shall have any further obligation to the other, 
except for obligations under collateral or separate agreements that may 
continue in force thereafter, including, without limitation, the Consulting 
Agreement.

          (c)     In the event Biomune shall give Ritter its Option Exercise 
Notice and there shall have been, prior to the Second Closing Date, a Material 
Adverse Change at Biomune as defined in Section 4.9 hereof which is not a 
Breach hereunder, Ritter may elect to rescind this Agreement and refuse to 
sell the Shares to Biomune.  In such event, Biomune shall have no recourse 
other than to receive repayment of the full Option Price paid through the date 
of rescission.  Following such rescission and payments to Biomune, no party 
hereto shall have any further obligation to the other, except for obligations 
under collateral or separate agreements that may continue in force thereafter, 
including, without limitation, the Consulting Agreement.

     3.   REPRESENTATIONS AND WARRANTIES OF SELLERS

               (v)     contravene, conflict with, or result in a violation or 
breach of any provision of, or give any Person the right to declare a default 
or exercise any remedy under, or to accelerate the maturity or performance of, 
or to cancel, terminate, or modify, any material Applicable Contract; or 

               (vi)    result in the imposition or creation of any 
Encumbrance upon or with respect to any of the material assets owned or used 
in the Business.

          (c)     No Seller is or will be required to give any notice to or 
obtain any Consent from any Person in connection with the execution and

     3.4     FINANCIAL STATEMENTS

     Prior to the First Closing Date or at such other time consented to by 
Biomune, Biomune shall have arranged for Arthur Andersen LLP, independent 
certified public accountants ("Auditor"), to prepare the Audits according to 
GAAS, from the books and records provided to it by the Sellers, and deliver 
the same to Sellers and Biomune.  Such Audits shall include: (a) audited 
consolidated balance sheets of Rockwood (including all majority-owned 
Subsidiaries, such as Drive) pursuant to GAAP as at the end of the fiscal 
years ended March 31, 1995, 1996 and 1997 and (b) the related audited 
consolidated statements of income, changes in stockholder's equity, and cash

such fiscal years, together with the report thereon of the Auditor.  If the 
Second Closing Date is after May 15, 1998, then the Auditor shall also prepare 
such an Audit for the fiscal year ending March 31, 1998.  Prior to the Second 
Closing Date, Sellers likewise shall have caused the Interim Statements of 
Rockwood to be prepared pursuant to GAAP as at the end of the most recently 
completed calendar quarter immediately preceding such Second Closing Date, 
including the related unaudited consolidated statements of income, changes in 
stockholder's equity, and cash flows as at that date, and shall have delivered 
the same to Biomune.  The Interim Statements and all books and records 
provided to the Auditor in connection with its audit of the financial records 
of Rockwood fairly present in all material respects the financial condition 
and the results of operations, changes in stockholder's equity, and cash flows 
of Rockwood and its Subsidiaries as at the respective dates of and for the 
periods referred to therein, all in accordance with the usual and customary 
business operations of, and accounting practices followed by Rockwood, 
subject, in the case of Interim Statements, to normal recurring year-end and

sheets prepared by Rockwood reflect the consistent application of such 
accounting practices throughout the periods involved. 

     3.5     BOOKS AND RECORDS

     The books of account, minute books, stock record books, and other records 
of Rockwood, all of which have been made available to Biomune, are complete 
and correct in all material respects, and have been maintained in accordance 
with sound business practices.  The minute books of Rockwood contain accurate 
and complete records, in all material respects, of all meetings held of, and 
corporate action taken by, the stockholder and the board of directors of 
Rockwood, and no significant meeting of such stockholder or the board of 
directors has been held for which minutes have not been prepared and are not 
contained in such minute books.  At each Closing, all of those books and 
records will be in the possession of Rockwood.

     3.6     TITLE TO PROPERTIES; ENCUMBRANCES

     Part 3.6 of the Disclosure Letter contains a complete and accurate list 
of all leasehold interests in real property owned by Rockwood.   Sellers have 
delivered or made available to Biomune copies of the leases by which Rockwood  
holds such interests.   Rockwood owns no real property.   Subject only to the 
matters permitted below in this Section, all the leasehold interests in real 
property and other assets (whether real, personnel, or mixed and whether

reflected in the Interim Statements (except for (i) assets held under 
capitalized leases disclosed in the Disclosure Letter, (ii) personal property 
sold since the date of the Interim Statements in the Ordinary Course of 
Business, and (iii) assets purchased or otherwise acquired by Rockwood since

such properties and assets, (a) mortgages or security interests shown within 
the audited financial statements or the Interim Statements as securing 
specified liabilities or obligations, with respect to which, no default (or 
event that, with notice or lapse of time or both, would constitute a default) 
exists, (b) mortgages or security interests incurred in connection with the 
purchase of property or assets after the date of the Interim Statements  (such 
mortgages and security interests being limited to the property or assets so 
acquired), with respect to which, no default (or event that, with notice or 
lapse of time or both, would constitute a default) exists, and  (c) liens for 
current taxes not yet due.

     3.7     NO UNDISCLOSED LIABILITIES

     To the Knowledge of the Sellers, Rockwood has no material liabilities or 
obligations except for liabilities or obligations reflected or reserved 
against in the Interim Statements and liabilities, accrued, contingent or 
otherwise, incurred in the Ordinary Course of Business since the date thereof.

any Governmental Body and Rockwood has not given or been requested to give 
waivers or extensions (or, to the Knowledge of Sellers, is or would be subject 
to a waiver or extension given by any other Person) of any statute of 
limitations relating to the payment of Taxes of Rockwood or for which 
Rockwood  may be liable.

          (c)     The charges, accruals, and reserves with respect to Taxes on 
the books of Rockwood are reasonably adequate (determined in accordance with 
prior consistent accounting practices of Rockwood).  To the Knowledge of 
Sellers, there exists no proposed tax assessment against Rockwood except as 
disclosed in the Interim Statements or in the Disclosure Letter.  All Taxes 
that Rockwood is or was required by Legal Requirements to withhold or collect 
have been duly withheld or collected and, to the extent required, have been 
paid to the proper Governmental Body.  

          (d)     All Tax Returns filed by (or that include on a consolidated 
basis) Rockwood are true, correct, and complete in all material respects.

     5.5     PROCEDURE FOR INDEMNIFICATION--THIRD PARTY CLAIMS

          (a)     Promptly after receipt by an Indemnified Person or Seller 
(such Person or Seller being referred to herein as an "Indemnified Party") 
under Section 5.2, 5.3 or 5.4 of notice of the commencement of any Proceeding 
or other claim against it, such Indemnified Party will, if a claim is to be 
made against another party to this Agreement (hereinafter an "Indemnifying 
Party") under such Section, give notice to the Indemnifying Party of the 
commencement of such claim, but the failure to notify the Indemnifying Party 
will not relieve the Indemnifying Party of any liability that it may have to 
any Indemnified Person, except to the extent that the Indemnifying Party 
demonstrates that the defense of such action is prejudiced by the Indemnified 
Party's failure to give such notice.

          (b)     If any Proceeding referred to in Section 5.5(a) is brought 
against an Indemnified Party and it gives notice to the Indemnifying Party of 
the commencement of such Proceeding, the Indemnifying Party will be entitled 
to participate in such Proceeding and, to the extent that it wishes (unless the 
Indemnifying Party is also a party to such Proceeding and the Indemnified 
Party determines in good faith that joint representation would be 
inappropriate), to assume the defense of such Proceeding with counsel 
reasonably satisfactory to the Indemnified Party and, after notice from the 
Indemnifying Party to the Indemnified Party of its election to assume the 
defense of such Proceeding, the Indemnifying Party will not, as long as it 
diligently conducts such defense, be liable to the Indemnified Party under 
this Section 5 for any fees of other counsel or any other expenses with 
respect to the defense of such Proceeding, in each case subsequently incurred 
by the Indemnified Party in connection with the defense of such Proceeding.   
If the Indemnifying Party assumes the defense of a Proceeding (i) no 
compromise or settlement of such claims may be effected by the Indemnifying 
Party without the Indemnified Party's consent unless (A) there is no finding 
or admission of any violation of Legal Requirements or any violation of the 
rights of any Person and no effect on any other claims that may be made 
against the Indemnified Party, and (B) the sole relief provided is monetary 
damages that are paid in full by the Indemnifying Party; and (ii) the 
Indemnified Party will have no liability with respect to any compromise or 
settlement of such claims effected without its consent.  If notice is given to 
an Indemnifying Party of the commencement of any Proceeding and the 
Indemnifying Party does not, within thirty (30) days (or such shorter period 
within which a response to the Proceeding is due in order to comply with the 
applicable rules of such Proceeding, as said period may be extended) after the 
Indemnified Party's notice is given, give notice to the Indemnified Party of 
its election to assume the defense of such Proceeding, the Indemnifying Party 
will be bound by any determination made in such Proceeding or any compromise 
or settlement effected by the Indemnified Party.  

          (c)     Notwithstanding the foregoing, if an Indemnified Party 
determines in good faith that there is a reasonable probability that a 
Proceeding may adversely affect it or its Affiliates other than as a result of 
monetary damages for which it would be entitled to indemnification under this 
Agreement, the Indemnified Party may, by notice to the Indemnifying Party, 
assume the exclusive right to defend, compromise, or settle such Proceeding, 
but the Indemnifying Party will not be bound by any determination of a 
Proceeding so defended or any compromise or settlement effected without its 
consent (which may not be unreasonably withheld) therein.

          (d)     Sellers and Biomune hereby consent to the non-exclusive 
jurisdiction of any court in which a Proceeding is brought against any 
Indemnified Party for purposes of any claim that an Indemnified Party may have 
under this Agreement with respect to such Proceeding or the matters alleged 
therein, and agree that process may be served on them with respect to such a 
claim anywhere in the world.

     5.6     PROCEDURE FOR INDEMNIFICATION--OTHER CLAIMS

     A claim may be asserted only by written notice to the party from whom 
indemnification is sought.  Except for equitable remedies, the remedies 
provided in this Agreement constitute the sole and exclusive remedies for 
recovery against the parties based upon the inaccuracy, untruth, 
incompleteness or Breach of any representation or warranty or covenant 
(excluding the investment representations given by Biomune) contained herein 
or in any certificate, disclosure schedule or Closing Document furnished in 
connection herewith.

     6.     OTHER AGREEMENTS OF THE PARTIES

     In addition to the other terms and conditions contained in this 
Agreement, the parties agree as follows:

     6.1     DEFINED BENEFIT PLAN

     Prior to the Second Closing Date, the Rockwood defined benefit plan will 
be terminated and the participant of such plan will have rolled his interest 
thereunder into a plan for which neither Rockwood nor Biomune nor any of their 
Affiliates shall have any liability or responsibility; and

     6.2     ASSIGNMENT OF CONTRACTS

     All Contracts relating to the Business which have previously been entered 
into in the name(s) of Andela, Ritter or some other Related Person or 
Affiliate of any of the Sellers shall have been duly assigned to and assumed 
by Rockwood prior to the Second Closing Date.

     6.3     PROVISION OF INFORMATION

     As long as Biomune owns the Option, Rockwood covenants to prepare and 
furnish to Biomune quarterly and annual financial statements and such other 
reports and financial information as Biomune may reasonably request, together 
with a discussion and analysis of such statements in form and substance 
substantially similar to those that Biomune would be required to include on a 
consolidated basis with its own reports filed with the SEC for the period(s) 
covered by such statements and reports.

     6.4     COVENANTS OF BIOMUNE

          (a)     Biomune agrees to use its Best Efforts to obtain all 
necessary consents and approvals that may be required in order to effect the 
exercise of the Option, including any approvals required in connection with 
the obligations of Biomune under the Employment Agreement.

          (b)     Biomune shall use its Best Efforts as soon as reasonably 
practicable and prior to the expiration of the Option to raise no less than 
$5,000,000 in public or private equity capital.

     6.5     EXCLUSIONS FROM BUSINESS.

     The parties understand and agree that Ritter may from time-to-time 
develop new businesses and acquire interests in or control of businesses that 
may be similar to the Business as conducted by Rockwood on the First Closing 
Date.  Notwithstanding anything herein to the contrary, Ritter shall not be 
obligated to place any new development of products or methods, or any acquired 
or newly-formed business, whether or not similar in nature to the Business as 
conducted by Rockwood, under the control of Rockwood, and that notwithstanding 
the fact that such development, formation or acquisition may occur prior to 
the Second Closing Date, such interests may be maintained and operated by 
Ritter separate and apart from Rockwood or Biomune after the Second Closing 
Date.  To the extent, however, that after March 31, 1997, Ritter shall have 
developed or acquired (including without limitation Drive or Fairchild), or 
shall develop or acquire such new businesses or projects within, or shall have 
assigned or shall assign the same to Rockwood, making them part of the 
Business, then following the Second Closing Date, Biomune shall cause Rockwood 
to pay to Ritter a royalty equal to 5% of the gross revenues produced by such 
new businesses and projects.

     6.6     ASSETS AND LIABILITIES OF ROCKWOOD

     On the Second Closing Date, the assets of Rockwood, including cash and 
deposits, reserves for doubtful accounts and accounts receivable, will exceed 
the liabilities of Rockwood and shall be sufficient for the payment of any 
liability accruing to Rockwood prior to the Second Closing Date.  Following 
the Second Closing Date, Biomune shall operate Rockwood in good faith and 
shall use its Best Efforts to collect the accounts receivable as they exist at 
such date.  Cash received from the collection of such accounts receivable in 
the Ordinary Course of Business shall remain in the Business and Biomune shall 
apply the same to the payment of Rockwood's liabilities as follows: (a) to the 
payment of any amount outstanding on the Rockwood line of credit with Far East 
National Bank, (b)  to the payment of trade accounts payable; and (c) to 
Ritter.  Any liabilities of Rockwood, singly or in the aggregate in excess of 
$10,000 that are otherwise due as of the Second Closing Date that are not 
reflected or recorded within the Interim Statements or the Audit for March 31, 
1998, as the case may be, shall be the sole and exclusive liability of Ritter

under the Transaction Documents.

business or trades with  Biomune;

          b.  Unless otherwise expressly directed by Biomune, have any

known to either of them to be employed by or represent news media;

dispute; and

          e.  directly or indirectly, in any capacity, engage or participate

connection with any business and any branch, office or operation thereof, 
which is a competitor of Biomune in providing similar goods and services to 
the biopharmaceutical or nutraceutical markets.

Notwithstanding the foregoing and the covenants set forth in herein, Biomune 
acknowledges that although the parties agree that Ritter and Andela shall 
devote substantial time and effort to the performance of their duties 
hereunder, (i) Ritter, directly and indirectly (including through Andela 
and/or Rockwood), is presently the owner of certain entities engaged in 
manufacturing, marketing, distributing and promoting vitamins, health and 
personal care products, cosmetics and nutritional supplements; for his own accou
nt and for third parties, (ii) Ritter presently anticipates that he will seek 
to continue to operate such businesses and to seek additional opportunities in 
these and in other fields where he may take advantage of his knowledge, 
expertise and experience in marketing and distribution; and (iii) Ritter has a 
variety of business interests which occupy and require much of his time and 
attention.  Therefore, Biomune agrees that in connection with Andela and 
Ritter's performance of the services described above, (A) Ritter may actively 
pursue those business interests in which he is now engaged or in which he may 
become engaged during the term of this Agreement, provided the same do not 
violate the terms of the foregoing covenants, and (B) on infrequent occasion 
and from time to time, Ritter may not be immediately available to provide 
services to Biomune as and when requested by Biomune.  Ritter agrees to keep 
Biomune fully apprised of his personal schedule at all times and to devote 
such time as is required by Section 2 of this Agreement to his duties 
hereunder.

     11.     Services of Ritter Personal.  The parties agree that the services 
of Ritter are material to and a condition of this Agreement.  If at any time 
and for any reason during the term hereof, Ritter shall die or  become 
permanently incapacitated (as certified by a doctor mutually acceptable to the 
parties) or otherwise unable to continue to perform the duties and services 
contemplated by Biomune to be provided hereunder, then Biomune may terminate 
this Agreement  immediately without any further obligation or duty to Andela 
or any other person hereunder.

     12.     Independent Contractor.  Andela is an independent contractor 
under this Agreement.  This Agreement does not establish a partnership or 
joint venture.  Andela is solely responsible for its employees, including the 
terms of employment, wages, hours, required insurance and daily direction and 
control.

     13.     Counterparts.  This Agreement may be executed in any number of 
counterparts, each of which when so executed shall be deemed to be an 
original, and such counterparts together shall constitute one and the same 
instrument.

     14.     Attorney Fees and Costs.  The parties agree that should either 
party default in any of the covenants contained herein, the defaulting party 
will pay all costs and expenses, including reasonable attorneys' fees, which 
may arise from the enforcement of this agreement, whether such enforcement is 
pursued by filing of a suit or otherwise.  This Agreement is governed by the 
laws of the state of Utah applicable to agreements intended to be performed 
within such state.
