ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

        On September 30, 1997, Simulation Sciences Inc. (the "Registrant") 
completed the acquisition  (the "Acquisition") of  substantially all of the  
assets of W.R. Biles & Associates, Inc. ("Biles and Associates") pursuant to 
an Asset Purchase Agreement dated as of September 30, 1997  by and among the 
Registrant, Biles and Associates and William R. Biles (the "Asset Purchase 
Agreement").

        Pursuant to the Asset Purchase Agreement, the purchase price for the
assets was approximately $5.1 million, including a cash payment of $2.5 million
and the assumption of approximately $2.6 million in net liabilities. The
purchase price is subject to certain post-closing adjustments based upon Biles
and Associates' financial condition as of September 30, 1997. Of the cash
portion of the purchase price, approximately $625,000 will be held in an Escrow
Fund for a period of one year. The Escrow Fund is available to compensate the
Registrant for any losses that it incurs as a result of any inaccuracy or breach
of a representation or warranty of Biles and Associates and Mr. Biles contained
in the Asset Purchase Agreement or any failure by Biles and Associates and Mr.
Biles to comply with any covenant contained therein.

        Biles & Associates, a Houston-based corporation, provides process
information management solutions to companies in the chemicals, pharmaceuticals,
food and beverage, semiconductor, consumer products and other industries. The
assets acquired in the Acquisition include Biles and Associates' industry-proven
AIM-Supervisor System and the new AIM/AT Suite of products and technology, which
have been recognized for their open architecture, adherence to industry
standards and ease of integration with enterprise systems such as R/3 from SAP.
The AIM/AT Suite leverages the Windows NT operating environment and employs a
completely new architecture based on object-oriented technology and the
client/server model.

        The Registrant's press release announcing the closing of the Acquisition
and the Asset Purchase Agreement relating thereto are filed as exhibits to this
Current Report on Form 8-K. The foregoing summary description of the Acquisition
is qualified in its entirety by reference to the documents filed as exhibits
hereto.

        The foregoing description of the Acquisition contains forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended,
including the statements regarding post-closing adjustments in the purchase
price for the assets and amounts that may be recovered by the Registrant out of
the Escrow Fund. The amount of any post-closing adjustment is unknown, and the
amount of any claims the Registrant may have against the Escrow Fund is
uncertain and may ultimately be more or less than the amount for which the
Escrow Fund provides as a result of a number of factors, including but not
limited to disruptions in relations with, or adverse reactions by, or greater
than anticipated obligations owing to, existing Biles and Associates customers
that will become customers of the Registrant, and the other risks described in
the Registrant's most recent report on Form 10-Q and Form 10-K filed with the
Securities and Exchange Commission.

                            ASSET PURCHASE AGREEMENT


        This ASSET PURCHASE AGREEMENT (the "Agreement") is made and entered into
as of September 30, 1997 by and among Simulation Sciences Inc., a Delaware
corporation ("Buyer"), W.R. Biles & Associates, Inc., a Delaware corporation
("Seller") and William R. Biles, a co-founder and the principal stockholder of
Seller (the "Stockholder" and collectively with Seller, the "Sellers").

                                R E C I T A L S:

        A. Seller is engaged in the business of providing information management
and supervisory control software and engineering services to the process
industries and certain other manufacturers, and is the owner of certain tangible
and intangible assets, which assets are used in such business and together
constitute the "Assets". The Assets include without limitation certain software
including the AIM Suite and the AIM/AT Suite (the "Software"), such Assets as
more fully described on Exhibit A hereto. The Assets, together with all other
elements, practices and personnel necessary to sustain Seller as presently
operated and as proposed by Seller's current management to be operated together
constitute the "Business."

        B. Seller wishes to sell the Assets to Buyer and Buyer wishes to acquire
such Assets and assume certain specified liabilities of Seller relating to the
Business on the terms set forth in this Agreement (the "Acquisition").


                               A G R E E M E N T:

        NOW, THEREFORE, in consideration of the representations, warranties and
covenants set forth herein, the parties agree as follows:


                                    ARTICLE I

                                 THE ACQUISITION

        1.1    Purchase of Assets.

               (a) Purchase and Sale of Assets. On the terms and subject to the
conditions set forth in this Agreement, and on the Closing Date (as defined in
Section 1.4(a)), Seller will sell, convey, transfer, assign and deliver to Buyer
and Buyer will purchase and acquire from Seller, all of Seller's right, title
and interest in and to the Assets free and clear of all liens, pledges, charges,
claims, security interests or other encumbrances of any sort (collectively,
"Liens"), except for liens for taxes not yet due and payable and statutory liens
arising in the ordinary course of the Business, provided such liens are 


<PAGE>   7


not material and/or are disclosed on Schedule 2.4 hereto ("Permitted Liens"). 
The Assets include without limitation the following:

                       (i) all patents, patent applications, copyrights, 
trademarks, service marks, trade names, trade secrets, proprietary information, 
technology rights and licenses, all electronic rights, multimedia rights, 
interactive rights, moral rights, new media rights, reacquisition rights and 
publication rights, proprietary rights and processes, know-how, research and 
development in progress, and any and all other intellectual property including, 
without limitation, all things authored, discovered, conceived or first reduced 
to practice by Seller or any of its employees in the course of their employment 
by Seller that pertain to the Assets, whether tangible or intangible, in any 
stage of development and all rights of any kind in or to any of the foregoing
(collectively, the "Intellectual Property");

                      (ii) all rights and ownership of the Software, including
but not limited to all versions of the Software, and all copies of the Software 
(including revisions and updates in process), and all technical, design, 
development, installation, operation and maintenance information concerning the 
Software, including source code, source documentation, source listings and 
annotations, engineering notebooks, test data and test results, all in 
sufficient detail to permit a reasonably skilled software developer not involved
in the development of the Software to maintain, enhance and correct errors in 
the Software without assistance from or reference to any other persons or 
materials as well as all reference manuals and support materials normally 
distributed to end-users and potential end-users in connection with the 
distribution of the Software;

                      (iii) all of Seller's claims against any parties relating
to any Asset, the Business or any Contract (as defined below) necessary to 
operate the Business or otherwise material to the Business, including without 
limitation, unliquidated rights under manufacturers' and vendors' warranties or 
guaranties; provided, however, that this Section 1.1(a)(iii) shall not apply to 
claims by Seller against Mr. Ron Hall, the former President of Seller; such 
rights against Mr. Hall shall be retained by Seller. "Contracts" shall mean all 
agreements, licenses and commitments, written or oral, relating to the Business 
or any of the Assets to which Seller is a party, beneficiary or by which it is 
bound;

                      (iv) all of Seller's rights pertaining to the Software
under any software development, consulting and maintenance Contracts;

                       (v) all other Assets, including, without limitation,
litigation claims, customer lists, potential customer lists, proposals, 
operating manuals, employee records, potential employee lists, accounting 
records, business strategy plans, projects under development, lead referral 
methods, co- selling arrangements, distribution methods and contacts, management
plans, related business opportunities and so on.

        To the extent delivery of the Assets involves physical delivery, Seller
shall be required to so deliver the Assets at the Closing (as defined in Section
1.4(a)).

               (b) Assumption of Obligations. Buyer shall assume only such
liabilities and obligations of Seller described on Exhibit B as "Assumed
Obligations" (collectively, the "Assumed Obligations"). Without limiting the
foregoing, it is expressly agreed that other than the Assumed Obligations as set
forth in Exhibit B, Buyer shall not assume (i) the liabilities and obligations
of Seller set forth in Exhibit C (the "Excluded Obligations") or (ii) any
liabilities or obligations for employment, income, sales, property or other
Taxes incurred or accrued by Seller or that would have been accrued by Seller
under generally accepted accounting principles assuming Seller reports taxes on

respective accountants) relating to the Closing Balance Sheet and all other
items reasonably requested by the CPA Firm. The "Adjusted Closing Balance Sheet"

Objection is delivered to Seller during the 4-day period immediately following
the delivery of the Closing Balance Sheet, or (B) Seller and Buyer so agree,
(ii) the Closing Balance Sheet, adjusted in accordance with Buyer's Objection in
the event that (A) Seller does not respond to Buyer's Objection within the 4-day
period following receipt by Seller of Buyer's Objection or (B) Seller and Buyer
so agree, or (iii) the Closing Balance Sheet, adjusted in accordance with the
mutual agreement of Seller and Buyer or (iv) the Closing Balance Sheet, as

               (c) Buyer shall provide Seller and its accountants full access to
the accounting records and any other information, including work papers of its
accountants, and to any employees to the extent reasonably necessary for Seller
to prepare the Closing Balance Sheet. Buyer and its accountants shall have full
access to all information used by Seller in preparing the Closing Balance Sheet,
including the work papers of its accountants.

               (d) Following finalization of the Adjusted Closing Balance Sheet,
the parties shall determine the "net value" of the following items of Seller on
its balance sheet as of the Closing Date: "Cash," "Fees Receivable" (less
allowance for doubtful accounts), "Note Receivable -- Biles N.V.," "Accounts
Payable," "Commissions Payable," "Note Payable -- S. Biles,"
"Royalty/Commissions Payable." For purposes of computing Closing Net Working
Capital as defined below, For the 8/20/97 Balance Sheet, this amount shall be
referred to hereinafter as the "8/20/97 Net Working Capital Deficit," and at
August 20, 1997 was equal to $734,000. For the Adjusted Closing Balance Sheet
this amount, less $25,000 shall be referred to hereinafter as "Closing Net
Working Capital Deficit."

               (e) In the event of a difference between the Closing Net Working
Capital Deficit and 8/20/97 Deficit, a "Purchase Price Adjustment" shall be made
as follows:

                      (i) If the Closing Net Working Capital Deficit is less
than the 8/20/97 Net Working Capital Deficit, Buyer shall, within 10 days, pay 
the difference to Seller in cash and deliver to

Escrow Agent and Seller a "Purchase Price Adjustment Escrow Cash Release Notice"
which shall instruct Escrow Agent to release the full amount of Purchase Price
Adjustment Escrow Cash to Seller.

                      (ii) If the Closing Net Working Capital Deficit is greater
than 8/20/97 Net Working Capital Deficit by an amount equal to or less than 
$100,000, then Buyer shall be responsible for satisfying such deficiency. 
Additionally, Buyer shall, within 10 days, deliver to Escrow Agent and the 
Seller the Purchase Price Adjustment Escrow Cash Release Notice.

                      (iii) If the Closing Net Working Capital Deficit exceeds 
the 8/20/97 Net Working Capital Deficit by an amount in excess of $100,000 but 
not greater than $400,000, then Buyer shall be entitled to permanently retain an
amount of the Purchase Price Adjustment Escrow Cash equal to such excess for 
purposes of satisfying such deficiency.

                      (iv) If the Closing Working Capital Deficit exceeds
$400,000, the amount of "Accounts Payable" and/or "Royalty Commissions Payable" 
to be assumed by Buyer shall be reduced to a level such that the Closing Net 
Working Capital Deficit does not exceed $400,000.

employees and whether or not subject to ERISA and (ii) the term "Plan" means
each Employee Benefit Plan set forth on Schedule 2.6(a) and each other Employee
Benefit Plan, if any, improperly omitted from such Schedule.

               (b) No Plan is (i) a defined benefit plan (as such term is

               (c) To the best of Seller's knowledge, the Plans (and all related
trusts, insurance contracts and funds) have been maintained, administered and
funded in accordance with their terms and in compliance with the requirements of
all applicable laws and regulations, including ERISA and the Code and the
reporting and disclosure and nondiscrimination rules thereof. Each Plan that is
an employee pension benefit plan intended to be qualified meets the requirements

respects with the requirements of Section 4980B of the Code and Part 6 of
Subtitle B of Title I of ERISA.

               (d) To the best of Seller's knowledge, with respect to each Plan,

Tax or penalty, including any Tax or penalty under ERISA or the Code or other
liability, (ii) no fiduciary (as defined in Section 3(21) of ERISA) has, or is
expected to have, any liability for breach of fiduciary duty or any other
failure to act or comply in connection with the administration or investment of
the assets of such plans, and (iii) no actions, investigations, suits or claims
(other than routine claims for benefits or routine actions seeking qualified
domestic relations orders) are pending or threatened, and the Seller has no
knowledge of any facts which would give rise to, or could reasonably be expected
to give rise to, any such actions, investigations, suits or claims. No Plan has
any unfunded liabilities.

               (e) Except as set forth on Schedule 2.6(e), none of the Plans
provide for separation, severance, termination, accelerated vesting or similar
type benefits that may be realized as a result of a "change in control."

any omissions which would give rise to severance pay, discrimination or other
employee related claims or damages.

set forth in Schedule 2.7, Seller has complied with all applicable laws, rules 
and regulations which relate to employment and collective bargaining (including 
pay and discrimination) and to the operation of its business and is not liable 
for any arrears of wages, contributions or any taxes or penalties for failure to
comply with any of the foregoing. Seller is not a party to, and is not
threatened with, any dispute or controversy with a union or with respect to
unionization or collective bargaining involving the employees of Seller.

        2.8    Agreements, Contracts and Commitments. Except as set forth on
Schedule 2.8, Seller has not breached, violated or defaulted under, or received
notice that it has breached, violated or defaulted under, any of the terms or
conditions of any Contract. Each Contract is in full force and effect and, to
the knowledge of Seller, the other party to such Contract has not breached,
violated or defaulted under any of the terms or conditions of any Contract.
Seller has obtained or will obtain prior to the Closing Date all necessary
consents, waivers and approvals of parties to any Contract as are required to
assign all rights and benefits thereunder to Buyer as of the Closing.

of Seller as of the dates and during the periods indicated therein.

        2.10   No Undisclosed Liabilities. Except as set forth in Schedule 2.10,

accounting principles), which individually or in the aggregate, (i) has not been
reflected in the Seller Financials, (ii) has not arisen in the ordinary course

firm corporation or business that engages in, or intends to engage in, the
Business anywhere in the world; or (ii) solicit for employment or hire, employ
or otherwise retain (whether as an employee, officer, agent, consultant, advisor
or in any capacity whatsoever) any New Employee, any employee of Seller who
refused an offer of employment by Buyer, or any employee of Buyer, without the
prior written consent of Buyer.

               (b) If the final judgment of a court of competent jurisdiction
declares that any term or provision of this Section 4.17 is invalid or
unenforceable, the parties agree that the court making the determination of
invalidity or unenforceability will have the power to reduce the scope, duration
or area of the term or provision, to delete specific words or phrases or to
replace any invalid or unenforceable term or provision with a term or provision
that is valid and enforceable and that comes closest to expressing the intention
of the invalid or unenforceable term or provision with a term or provision and
this Agreement will be enforceable as so modified.

        4.18   Termination of Seller/401(k) Plan. Seller shall cause its Profit
Sharing/401(k) Plan (the "Seller 401(k) Plan") to be terminated prior to the

practicable thereafter, not to exceed thirty (30) days following the Closing
Date, Buyer and Seller shall cause to be executed and deliver such documents
reasonably requested by American National Insurance Company ("Lessor") as
reasonably necessary to effect an assignment and assumption by Buyer of the
lease by and between Seller and Lessor dated December 11, 1995, as amended
September 1, 1996 and January 1, 1997 with respect to Seller's office facilities
located at 6161 Savoy Drive, Houston, Texas (the "Lease") which documents shall
include: (i) Assignment, Assumption and Consent to Lease among Buyer, Seller and
Lessor and (ii) an Estoppel Certificate in favor of Buyer. Nothing contained
herein shall obligate Buyer to assume any unperformed obligations or any other
liabilities under such lease incurred or accrued prior to the Closing Date;
provided, however, Buyer shall assume past due rent obligations under the Lease
up to the amount of $125,878. Buyer shall have the right to rescind such
assumption of the Lease in the event that (i) Lessor does not approve of consent
to the assignment of the Lease to Buyer or (ii) Lessor does not waive any
existing or prior defaults under the Lease.

                                    ARTICLE V

                                 INDEMNIFICATION

        5.1    Indemnity.

               (a) Escrow Funds. At the Closing Date, Buyer shall deposit the
Escrow Cash and the Purchase Price Adjustment Escrow Cash into escrow (the
"Escrow Fund") pursuant to the terms of the Escrow Agreement in substantially
the form attached hereto as Exhibit H (the "Escrow Agreement"). Buyer and Seller
agree to enter into and be bound by the Escrow Agreement. Payment to Seller of
the Escrow Cash placed in the Escrow Fund shall be contingent upon the
occurrence or nonoccurrence of those certain events as more fully set forth in
the Escrow Agreement and as set forth herein concerning indemnity, as
applicable.

               (b) Indemnity for Buyer's Benefit in the Event of Loss. Sellers
hereby agree, jointly and severally, to indemnify and hold Buyer and its
subsidiaries, directors, officers and agents harmless against and in respect of
any loss, cost, expense (including, without limitation, reasonable attorney
fees), claim, liability, deficiency, judgment or damage (hereinafter,
individually, a "Loss"; and collectively, "Losses") incurred by Buyer, its
subsidiaries, officers, directors and agents (i) as a result of any breach of a
covenant, representation or warranty of Sellers contained in this Agreement,
(ii) by reason of the failure of Sellers to perform their respective obligations
under this Agreement, (iii) any claim, under or with respect to any Employee
Benefit Plan, (iv) any claim for Taxes of Sellers relating to the period prior
to and including the Closing or (v) any claim that Sellers have violated any
Environmental Laws in connection with the ownership or operation of the
Business, (vi) any claim by Ron Hall against Seller in which Buyer is named or
can be reasonably be expected to be named or (vii) any claim as to which the
parties have mutually agreed in writing.

               (c) Interpretation. Solely for purposes of this Article V, the
existence and extent of any breach of any covenant, representation or warranty
under Article II referred to in Section 5.1(b) shall be determined by reading
such representation or warranty as if all materiality standards contained in
such representation or warranty (i.e., without reference to the qualifier
"material," "materially," "material to the Business as a whole," "in all
material respects," "in any material respect," "Material Adverse Effect" or
similar qualifiers), has been deleted from such representation or warranty in
its entirety.

        5.2    Expiration of Indemnification. The indemnification obligations 
under this Article V with respect to any Loss shall terminate at 5:00 p.m. 
Pacific Standard Time on the first anniversary of the


                                      -22-

<PAGE>   28

Closing Date, but shall not terminate as to any Loss (or a potential claim by an
appropriate party) asserted in good faith prior to such date; provided, however,
that the indemnification obligations referred to in Section 5(b)(iii)-(v) shall
survive until the expiration of the applicable statute of limitations, if any.
The indemnification obligations under this Article V with respect to any
Purchase Price Adjustment shall terminate upon (i) release of Purchase Price
Adjustment Cash, if applicable, in satisfaction of a Purchase Price Adjustment
in favor of Buyer, if any, or (ii) Escrow Agent's receipt of the Purchase Price
Adjustment Escrow Cash Release Notice from Buyer.

        5.3    Indemnification Procedure in the Event of Loss. In the event of a
claim by Buyer for indemnity is made by written notice thereof to Seller, on or
prior to the date one (1) year from the Closing Date (the "Escrow Cash Period"),
Buyer shall initially proceed to recover such Losses from the Escrow Cash. If
such Losses exceed the amount of Escrow Cash or if claims for such Losses are
made after the Escrow Cash Period, Buyer shall then proceed against the Sellers,
subject to the limitations set forth in Section 5.6 hereof.

        5.4    Indemnification Procedure in the Event of Purchase Price 
Adjustment. In the event of a claim by Buyer for indemnity as a result of the 
Closing Net Working Capital Deficit exceeding the 8/20/97 Net Working Capital 
Deficit by an amount greater than $100,000 is made by written notice to Escrow 
Agent and Seller, Buyer shall initially proceed to recover such deficiencies 
from the Purchase Price Adjustment Escrow Cash. Provided further, that if the 
Closing Net Working Capital Deficit exceeds $400,000, then the amount of 
"Accounts Payable" and/or "Royalty Commission Payable" to be assumed by Buyer 
shall be reduced to a level such that Closing Net Working Capital Deficit 
does not exceed $400,000.

        5.5    Additional Provisions. Nothing in this Article V or otherwise 
shall limit, in any manner, any remedy at law or equity, to which Buyer may be
entitled as a result of fraud by Sellers or any of their respective employees,
officers, directors or agents.

        5.6    Arbitration. Any controversy involving a claim by an indemnified
party pursuant to this Article V shall be finally settled by arbitration in
Orange County, California in accordance with the then current Commercial
Arbitration Rules of the American Arbitration Association; and judgment upon the
award rendered by the arbitrator may be entered in any court having jurisdiction
thereof. Such arbitration shall be conducted by an arbitrator chosen by mutual
agreement of Buyer and Sellers. Failing such agreement, the arbitration shall be
conducted by three independent arbitrators, none of whom shall have any
competitive interests with Buyer or Sellers. Buyer shall choose one such
arbitrator, Sellers shall choose one such arbitrator, and such two arbitrators
shall mutually select a third arbitrator. Any decision of two such arbitrators
shall be binding on Buyer and Sellers. Each party shall pay its own costs and
expenses (including counsel fees) of any such arbitration except that the
arbitrator can compel one party to pay all or a portion of the other party's
costs and expenses.

        5.7    Trigger for Indemnification Obligation; Maximum Obligation. 
Sellers shall not be responsible for any indemnification obligation under 
Section 5.1(b) until Buyer has incurred $25,000 in Losses), upon such event, 
Seller shall be responsible for the full amount of Losses incurred by Buyer, 
except as otherwise provided herein. The maximum amount payable by Seller under 
Section 5.1(b) shall be $2,500,000 and the maximum amount payable by Stockholder
under Section 5.1(b) shall be $1,750,000.

        5.8    Mediation. Buyer and Sellers agree to use reasonable efforts to
mediate claims for losses arising under this Agreement prior to engaging the
procedures set forth in this Article 5.

        5.9    Scope of Indemnity. Buyer acknowledges that, except for equitable
relief, including specific performance, or in the case of fraud, its sole and
inclusive remedy with respect to any and all claims relating to the subject
matter of this Agreement shall be pursuant to the indemnification provisions of
this Article V.

        8.5    Entire Agreement. This Agreement and the Exhibits hereto, each of
which is hereby incorporated into this Agreement and made a part hereof: (a)
constitute the entire agreement among the parties with respect to the subject
matter hereof and supersede all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof;
(b) are not intended to confer upon any other person any rights or remedies
hereunder, unless expressly provided otherwise; and (c) shall not be assigned by
operation of law (except in connection with a change in the jurisdiction of
incorporation of Buyer) or otherwise except as otherwise specifically provided.
The parties further acknowledge and agree that, in entering into this Agreement,
they have not in any way relied upon any oral or written agreements, statements,
promises, information, arrangements, understandings, representations or
warranties, express or implied, not specifically set forth in this Agreement.

        8.6    Severability. In the event that any provision of this Agreement 
or the application thereof becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision (including, if applicable, one that limits the scope or
duration of the covenants contained herein) that will achieve, to the extent
possible, the economic, business and other purposes of such void or
unenforceable provision.

        8.7    Other Remedies. Except as otherwise provided herein, including
Section 5.6, any and all remedies herein expressly conferred upon a party will
be deemed cumulative with and not exclusive of any other remedy conferred
hereby, or by law or equity upon such party, and the exercise by a party of any
one remedy will not preclude the exercise of any other remedy. The parties
hereto agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their

BREA, Calif.--BUSINESS WIRE)--Oct. 1, 1997--SIMULATION SCIENCES INC. (SIMSCI)

The AIM/AT Suite leverages the Windows NT operating environment and employs a
completely new architecture based on object-oriented technology and the
client/server model.

Robert A. Harris, president and chief executive officer of Biles & Associates,
said: "The SIMSCI-Biles combination creates a great opportunity for our
customers to build upon the data management benefits we have provided by
leveraging SIMSCI's simulation and optimization technology. We strongly believe

are impressed with the loyalty of the Biles customers. By choosing Biles, they
have selected a best-in-class solution for process information management. We
are committed to help them leverage this investment and extend its benefits
through continuing to support their installations and by integrating the Biles'

models and effective information management and integration technology to help
manufacturers make more informed decisions on how to run their business to
maximize profits," continued SIMSCI's Harris. "We believe Biles' products
