Ladies and Gentlemen:

                  NATUR-PHARMA INC., a Utah corporation, which will be the
surviving entity of the Natur-Pharma Merger described below, proposes to issue
and sell to Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ") and
Chase Securities Inc. ("Chase") (collectively, the "Initial Purchasers") an
aggregate of $100,000,000 principal amount of 10 1/4% Senior Subordinated Notes
due 2006 (the "Securities"), subject to the terms and conditions set forth
herein, which notes are unconditionally guaranteed by Advanced Research Press,
Inc. ("ARP") and TLG Laboratories Holding Corp. (the "Holding Company", and
together with ARP, the "Guarantors"). As used herein, the "Company" means (i)
prior to the effectiveness of the Natur-Pharma Merger, Natur-Pharma Inc.
("Natur-Pharma"), and (ii) after the effectiveness of the Natur-Pharma Merger,
Twin Laboratories Inc. The Securities are to be issued pursuant to the
provisions of an Indenture (the "Indenture") to be dated as of May 7, 1996, by
and among the Company, the Guarantors and Fleet National Bank, as Trustee (the
"Trustee").

                  Pursuant to the Stock Purchase and Sale Agreement dated as
of March 5, 1996 (the "Acquisition Agreement"), by and among Messrs. Brian,
Dean, Neil, Ross,
   2
Steve and David Blechman and Stephen Welling and Ms. Jean Blechman
(collectively, the "Stockholders"), the Holding Company, the Company and Green
Equity Investors II, L.P. ("GEI"), among other things, (i) the Holding Company
will acquire all of the outstanding capital stock of Natur-Pharma and the
Company will become a wholly owned subsidiary of the Holding Company, (ii) Twin
Laboratories Inc., Alvita Products, Inc., Twinlab Export Corp., Twinlab
Specialty Corporation and B. Bros. Realty Corporation (together with ARP, the
"Affiliated Companies") will be merged into Natur-Pharma (the "Natur-Pharma
Merger"), and (iii) ARP will be merged with Natur-Pharma II Inc., a wholly owned
subsidiary of Natur-Pharma, with ARP surviving the merger and becoming a wholly
owned subsidiary of Natur-Pharma (the "Natur-Pharma II Merger") (the above
transactions are herein referred to as the "Acquisition"). In connection with
the Acquisition, the Company's name will be changed from Natur-Pharma Inc. to
Twin Laboratories Inc. Concurrently with the issuance and sale of the
Securities, the Company and the Guarantors will enter into a Credit Facility
(the "New Credit Facility") with Chemical Bank, as managing agent, and certain
lenders named therein which will consist of (i) a term loan in the amount of $53
million, and (ii) a revolving credit facility in the aggregate amount of $15
million, and in connection with the Acquisition and the Acquisition Agreement,
(i) GEI will acquire approximately 48% of the common stock of the Holding
Company for aggregate consideration of $4.8 million and shares of non-voting
junior redeemable preferred stock of the Holding Company for aggregate
consideration of $37.0 million, and (ii) certain other investors will acquire
approximately 7% of the common stock of the Holding Company for aggregate
consideration of $0.7 million and shares of non-voting senior redeemable
preferred stock of the Holding Company for aggregate considerations of $30.0
million.

                  For purposes of this Agreement, the term "Securities" means
the $100,000,000 aggregate principal amount of the notes of the Company (the
"Notes"), together with the guarantees (the "Guarantees") thereof by the
Guarantors. The Securities and the Indenture are more fully described in the
Offering Memorandum (as hereinafter defined). Capitalized terms used herein
without definition have the respective meanings specified in the Offering
Memorandum.

                  The Securities will be offered and sold to you without being
registered under the Securities Act of 1933, as amended (the "1933 Act"), in
reliance on an exemption therefrom. The Company and the Affiliated Companies
have prepared a preliminary offering memorandum dated April 19, 1996 (such
preliminary offering memorandum being hereinafter referred to as the
"preliminary offering memorandum"), and an offering memorandum dated May 1, 1996
(such offering memorandum, in the form first furnished to the Initial Purchasers
for use in connection with the offering of the Securities, being hereinafter
referred to as the "Offering Memorandum"), setting forth information regarding
the Company, the Holding Company, the Affiliated Companies and the Securities.
Unless otherwise explicitly provided for herein, all references herein to the
preliminary offering memorandum are to the preliminary offering memorandum at
April 19, 1996 and do not include any amendment or supplement subsequent
thereto. Each of the Company and the Affiliated Companies hereby confirms that
it has authorized the use of the preliminary offering memorandum and the
Offering Memorandum, and any amendments and supplements thereto, by the Initial
Purchasers in connection with the offering and resale by the Initial Purchasers
of the Securities in accordance with the terms and provisions of this Agreement.

                  Holders (including subsequent transferees) of the Securities
will have the registration rights set forth in the Registration Rights Agreement
(the "Registration Rights Agreement"), to be dated the Closing Date (as
hereinafter defined), in substantially the form of Exhibit A hereto. Pursuant to
the Registration Rights Agreement, the Company and the Guarantors will agree to
file with the Securities and Exchange Commission (the "Commission") under the
circumstances set forth therein, (i) a registration statement under the 1933 Act
(the "Exchange Offer Registration Statement") registering an issue of senior
subordinated notes identical in all material respects to the Securities (the
"Exchange Securities") to be offered in exchange for the Securities (the
"Exchange Offer") and (ii), under the circumstances set forth therein, a
registration statement pursuant to Rule 415 under the 1933 Act (the "Shelf
Registration Statement").

Agreement, and subject to the terms and conditions herein set forth, the Compa-
ny, as to the Notes, and, the Guarantors, as to the Guarantees, agree to issue

ties in the respective principal amount set forth opposite their names on
Schedule A hereto.

         2.       Delivery and Payment. Delivery to you of and payment for the

                  One or more of the Securities in definitive form, registered

         3.       Offering of the Securities and the Initial Purchasers'
Representations.

                  (a)      You have advised the Company that it is your
intention, as promptly as you deem appropriate after the Company shall have

forth in the Offering Memorandum.

                  (b)      Each Initial Purchaser represents, warrants and
agrees with respect to itself, that such Initial Purchaser:

                           (i)      is not acquiring the Securities with a view
                  to any distribution thereof or with any present intention of
                  offering or selling any of the Securities in a transaction
                  that would violate the 1933 Act or the securities laws of any
                  State of the United States or any other applicable
                  jurisdiction;

                                        5
   6
                           (ii)     will solicit offers for Securities only
                  from, and will offer Securities only to, persons that it
                  reasonably believes are (x) QIBs within the meaning of Rule
                  144A in transactions meeting the requirements of Rule 144A and
                  that, in connection with each such sale, it has taken or will
                  take reasonable steps to ensure that the purchaser of such
                  Securities is aware that such sale is being made in reliance
                  on Rule 144A, (y) a limited number of other institutional
                  "accredited investors" (as defined in Rule 501(a)(1), (2), (3)
                  or (7) under the 1933 Act ("Institutional Accredited
                  Investors")) which the Initial Purchaser maintains on its list
                  of persons regularly contacted regarding Rule 144A offerings
                  and which regularly conduct business with such Initial
                  Purchaser or (z) institutions that are outside the United
                  States and are not U.S. persons (and are not purchasing for
                  the account or benefit of a U.S. person) within the meaning of
                  Regulation S under the 1933 Act;

                           (iii)    will offer and sell the Securities only (x)
                  to persons who it reasonably believes to be QIBs, (y) to
                  institutions which it reasonably believes are Institutional
                  Accredited Investors that execute and deliver a letter
                  containing certain representations and agreements in the form
                  attached as Annex A to the Offering Memorandum or (z) to
                  institutions in transactions that occur outside the United
                  States within the meaning of Regulation S under the 1933 Act;

                           (iv)     is an Institutional Accredited Investor with
                  such knowledge and experience in financial and business
                  matters as are necessary in order to evaluate the merits and
                  risks of an investment in the Securities;

                                        6
   7
                           (v)      has not and will not offer or sell the
                  Securities by any form of general solicitation or general
                  advertising, including but not limited to the methods
                  described in Rule 502(c) of Regulation D under the 1933 Act;
                  and,

                           (vi)     is not a pension or welfare plan (as defined
                  in Section 3 of the Employee Retirement Income Act of 1974, as
                  amended, or the rules and regulations promulgated thereunder
                  ("ERISA")) and it is not acquiring the Securities on behalf of
                  a person whose funds to be used for the purchase of the
                  Securities constitute assets allocated to any qualified trust
                  that contains the assets of any employee benefit plan with
                  respect to which the Company is a party in interest or
                  disqualified person or the use of such assets would not
                  constitute a non-exempt prohibited transaction under ERISA or
                  the Code. The representation made in the preceding sentence is
                  made solely in reliance upon such Initial Purchaser's review
                  of "Notice to Investors" in the Offering Memorandum, which
                  describes the employee benefit plans with respect to which the
                  Company is a party in interest or a disqualified person.

         4.       Agreements of the Company. Each of the Company and the
Guarantors, jointly and severally, agrees with each of you that:

                  (a)      It will advise you promptly and, if requested by any
         of you, confirm such advice in writing, (i) of the issuance by any
         state securities commission of any stop order suspending the
         qualification or exemption from qualification of any of the Securities
         for offering or sale in any jurisdiction, or the initiation of any
         proceeding for such purpose by any state securities commission or other
         regulatory authority, and (ii) of the happening of any event during
         such period as in your rea-

                                        7
   8
         sonable judgment, upon the advice of counsel, you are required to
         deliver an Offering Memorandum in connection with sales of the
         Securities by you which event makes any statement of a material fact
         made in the Offering Memorandum untrue or which requires the making of
         any additions to or changes in the Offering Memorandum (as amended or
         supplemented from time to time) in order to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading. Each of the Company, the Affiliated Companies and the
         Guarantors shall use its best efforts to prevent the issuance of any
         order suspending the qualification or exemption of the Securities under
         any state securities or Blue Sky laws, and, if at any time, any state
         securities commission or other regulatory authority shall issue an
         order suspending the qualification or exemption of the Securities under
         any state securities or Blue Sky laws, the Company, the Affiliated
         Companies and the Guarantors shall use every reasonable effort to
         obtain the withdrawal or lifting of such order at the earliest possible
         time.

                  (b)      It will not make any amendment or supplement to the
         preliminary offering memorandum or the Offering Memorandum, of which
         you shall not previously have been advised and provided a copy within
         two business days prior to the delivery thereof or to which you shall
         reasonably object. During such period as in your reasonable judgment,
         upon advice of counsel, you are required to deliver an Offering
         Memorandum in connection with sales of the Securities, the Company and
         the Guarantors shall promptly prepare, upon your reasonable request,
         any amendment or supplement to the Offering Memorandum that may be
         necessary or advisable in connection with resales of the Securities.

                  (c)      It will furnish to you and to those persons who you
         identify to the Company, without charge, as many copies of the Offering
         Memorandum (and of any amendments or supplements thereto) as you may
         reasonably request.

                                        8
   9
                  (d)      If, during such period as in your reasonable
         judgment, upon the advice of counsel, you are required to deliver the
         Offering Memorandum in connection with sales of the Securities by you,
         any event shall occur as a result of which it becomes necessary to
         amend or supplement the Offering Memorandum in order to make the
         statements therein, in light of the circumstances existing as of the
         date the Offering Memorandum is delivered to a purchaser, not
         misleading, or if it is necessary to amend or supplement the Offering
         Memorandum to comply with any law, it will promptly prepare an
         appropriate amendment or supplement to the Offering Memorandum so that
         the statements in the Offering Memorandum, as so amended or
         supplemented, will not, in the light of the circumstances existing as
         of the date the Offering Memorandum is so delivered, be misleading, and
         will comply with applicable law, and will furnish to you without charge
         such number of copies thereof as you may reasonably request.

                  (e)      It will cooperate with you and your counsel in
         connection with the registration or qualification of the Securities for
         offer and sale by you under the state securities or Blue Sky laws of
         such jurisdictions as you may reasonably request (provided, that
         neither the Company nor the Guarantors shall be obligated to qualify as
         a foreign corporation in any jurisdiction in which it is not so
         qualified or to take any action that would subject it to general
         consent to service of process in any jurisdiction in which it is not
         now so subject or to subject itself to general taxation in any such
         jurisdiction). The Company and the Guarantors will continue such
         qualification in effect so long as required by law for distribution of
         the Securities by you.

                  (f)      After the closing of the Exchange Offer, the Company
         will, so long as the Securities are outstanding, file on a timely basis
         with the Commission, to the extent such filings are accepted by the
         Commission, and whether or not the Company has a class of securities
         reg-
                                        9

         istered under the Securities Exchange Act of 1934, as amended (the
         "1934 Act"), the annual reports, quarterly reports and other documents
         that the Company would be required to file if it were subject to
         Section 13 or Section 15 of the 1934 Act. For a period of five (5)
         years hereafter and thereafter for so long as you are making a market
         in the Securities, the Company will furnish to you copies of all such
         reports and information, together with such other documents, reports
         and information as shall be furnished by the Company to the holders of
         the Securities, and such other information concerning the Company and
         its Subsidiaries as you may reasonably request.

                  (g)      For so long as and at any time that it is not subject
         to Section 13 or 15(d) of the 1934 Act, the Company, upon request of
         any holder of the Securities, will furnish to such holder, and to any
         prospective purchaser or purchasers of the Securities designated by
         such holder, information satisfying the requirements of subsection
         (d)(4)(i) of Rule 144A under the 1933 Act; provided, however, that the
         Company's obligations under this Section 4(g) shall terminate upon the
         earlier of (i) the date the Exchange Offer is concluded and the
         exchange of the Exchange Securities for the Securities tendered therein
         is consummated or (ii) the date the Shelf Registration Statement is
         declared effective by the Commission; provided further that,
         notwithstanding the foregoing proviso, the Company shall be obligated
         to deliver, upon request, any information required by Rule
         144A(d)(4)(i) under the Act to prospective purchasers of the Securities
         during any period during which, pursuant to the Registration Rights
         Agreement, the Shelf Registration Statement is required to be
         effective, but such effectiveness has been suspended or revoked for any
         reason.

                  (h)      Whether or not the transactions contemplated hereby
         are consummated or this Agreement is terminated, it will pay and be
         responsible for all costs, expenses, fees and

                                       10
   11
         taxes in connection with or incident to (i) the printing, processing
         and distribution of the preliminary offering memorandum, the Offering
         Memorandum and all amendments or supplements thereto, including such
         copies as may be requested for use in connection with resales by you,
         (ii) the issuance and delivery of the Securities, (iii) the
         registration or qualification of the Securities for offer and sale
         under the securities or Blue Sky laws of the jurisdictions referred to
         in paragraph (e) above (including, in each case, any filing fees in
         connection therewith and the fees and disbursements of counsel relating
         thereto), (iv) the rating of the Securities by investment rating
         agencies, (v) the inclusion of the Securities on the National
         Association of Securities Dealers, Inc. (the "NASD") Automatic
         Quotation System-PORTAL ("PORTAL") and the approval of the Securities
         by DTC for "book-entry" transfer and (vi) the performance by each of
         the Company and the Guarantors of its other obligations under this
         Agreement, including (without limitation) the fees of the Trustee, the
         cost of its personnel and other internal costs, the cost of printing
         and engraving the certificates representing the Securities, and all
         expenses and taxes incident to the sale and delivery of the Securities
         to you.

                  (i)      It will use the proceeds from the sale of the
         Securities in the manner described in the Offering Memorandum under the
         caption "Use of Proceeds."

                  (j)      It will use its reasonable efforts to, and will use
         its reasonable efforts to cooperate with you to, cause the Securities
         to be designated PORTAL securities in accordance with the rules and
         regulations of the NASD.

                  (k)      It will not voluntarily claim, and will actively
         resist any attempts to claim, the benefit of any usury laws against the
         holders of the Securities.

                                       11
   12
                  (l)      It will use its reasonable best efforts to do and
         perform all things required to be done and performed under this
         Agreement by it prior to or after the Closing Date and will use its
         reasonable best efforts to satisfy all conditions precedent on its part
         to the delivery of the Securities.

                  (m)      Except in connection with the Exchange Offer or the
         filing of the Shelf Registration Statement, as the case may be, it will
         not, and will not authorize or knowingly permit any person acting on
         its behalf to, solicit any offer to buy or offer to sell the Securities
         by means of any form of general solicitation or general advertising
         (including, without limitation, as such terms are used in Regulation D
         under the 1933 Act) or in any manner involving a public offering within
         the meaning of Section 4(2) of the 1933 Act.

                  (n)      Neither the Company nor any affiliate (as such term
         is defined in Rule 501(b) under the 1933 Act) of the Company will
         offer, sell or solicit offers to buy or otherwise negotiate in respect
         of any "security" (as defined in the 1933 Act) which could be expected
         to be integrated with the sale of the Securities in a manner that would
         require the registration of the Securities under the 1933 Act.

                  (o)      It will not, so long as the Securities are
         outstanding, be or become an open-end investment company, unit
         investment trust or face-amount certificate company that is or is
         required to be registered under Section 8 of the Investment Company Act
         of 1940, as amended.

                  (p)      It will, prior to the Closing Date, furnish to the
         Initial Purchasers a copy of any unaudited interim combined financial
         statements of the Company for any period subsequent to the period
         covered by the most recent financial statements appearing in the
         Offering Memorandum.

                  (q)      Each Security will bear the following legend until
         such legend shall no longer be necessary or advisable because the
         Securities are no longer subject to the restrictions on transfer
         described therein:

                  "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
STATE SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION
HEREIN MAY BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR
OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION UNLESS SUCH
TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

                  THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF AGREES
NOT TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE
"RESALE RESTRICTION TERMINATION DATE") THAT IS THREE YEARS (OR SUCH SHORTER
PERIOD THAT MAY HEREAFTER BE PROVIDED UNDER RULE 144(K) AS PERMITTING THE RESALE
BY NON-AFFILIATES OF RESTRICTED SECURITIES WITHOUT RESTRICTION) AFTER THE LATER
OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH THE COMPANY OR ANY
AFFILIATED PERSON OF THE COMPANY WAS THE OWNER OF THIS SECURITY (OR ANY
PREDECESSOR OF SUCH SECURITY) EXCEPT (A) TO THE COMPANY, (B) PURSUANT TO A
REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES
ACT, (C) PURSUANT TO RULE 144A, FOR SO LONG AS IT IS AVAILABLE, TO A PERSON IT
REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN RULE 144A

OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS
BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES THAT OCCUR
OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE

OF RULE 501(A)(1),(2),(3) OR (7) UNDER THE SECURITIES ACT THAT IS ACQUIRING THE
SECURITY FOR ITS OWN ACCOUNT, OR FOR THE ACCOUNT OF SUCH AN INSTITUTIONAL
"ACCREDITED INVESTOR," FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO, OR FOR
OFFER OR SALE IN CONNECTION WITH, ANY DISTRIBUTION IN VIOLATION OF THE
SECURITIES ACT, OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY'S AND
THE TRUSTEE'S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE
(D),(E) OR (F)

TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND OTHER
INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES, A
CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THIS SECURITY IS COMPLETED AND
DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE REMOVED UPON THE
REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE."

                  (r)      During the period of three years after the Closing
         Date or such shorter period as provided by any amendment to Rule 144
         under the 1933 Act, the Company will not, and will not permit any of
         its "affiliates" (as defined in Rule 144 under the 1933 Act) to, resell
         any of the Securities which constitute "restricted securities" under
         Rule 144 that have been reacquired by any of them.

                  (s)      For so long as the Initial Purchasers shall hold any
         Securities, but in no event longer than three years from the date
         hereof, the Company shall, upon the Company's becoming a party in
         interest or disqualified person with respect to any "employee benefit
         plan" (as defined in Section 3(3) of the Employee Retirement Income
         Security Act of 1974, as amended ("ERISA")) other than any such plans
         described in "Notice to Investors" in the Offering Memorandum, (i)
         promptly notify the Initial Purchasers, in writing, of such event, and
         (ii) as soon as practicable thereafter, amend the "Notice to Investors"
         section of the Offering Memorandum to reflect such event.

         5.       Representations and Warranties. Each of the Company and the
Guarantors, jointly and severally, represents and warrants to each of you that:

                  (a)      Each of the preliminary offering memorandum and the
         Offering Memorandum, as of its date, contains all the information that,
         if requested by a prospective purchaser, would be required to be
         provided pursuant to Rule 144A(d)(4)(i) under the 1933 Act. The
         Offering Memorandum does not, and at the Closing Date, the Offering
         Memorandum and any amendment or supplement thereto will not, contain
         any untrue

                                       14
   15
         statement of a material fact or omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading, and the preliminary offering memorandum, at the date
         thereof and as of the date hereof, did not contain any untrue statement
         of a material fact or omit to state a material fact necessary in order
         to make the statements therein, in light of the circumstances under
         which they were made, not misleading; except that the representations
         and warranties contained in this paragraph (a) shall not apply to
         statements in or omissions from the preliminary offering memorandum or
         the Offering Memorandum (or any supplement or amendment thereto) based
         upon and conforming with information relating to any Initial Purchaser
         furnished to the Company in writing by or on behalf of any Initial
         Purchaser expressly for use therein. The Company acknowledges for all
         purposes under this Agreement that the statements with respect to price
         and discount and the last paragraph on the cover page of the Offering
         Memorandum, the information contained under the caption "Plan of
         Distribution" in the preliminary offering memorandum and the Offering
         Memorandum, and the information regarding stabilization on the inside
         front cover of the preliminary offering memorandum and the Offering
         Memorandum (or any amendment or supplement thereto) constitute the only
         written information furnished to the Company by or on behalf of any
         Initial Purchaser expressly for use in the preliminary offering
         memorandum or the Offering Memorandum (or any amendment or supplement
         thereto) and that the Initial Purchasers shall not be deemed to have
         provided any other information (and therefore are not responsible for
         any such statement or omission) pertaining to any arrangement or
         agreement with respect to any party other than the Initial Purchasers.
         No contract or document that would be required to be described in the
         Offering Memorandum if the Offering Memorandum were contained in a
         registration statement on Form S-1 under the 1933 Act is not so
         described.

   16
                  (b)      To the Company's knowledge, no action has been taken
         with respect to the Company or any of its Subsidiaries, and no statute,
         rule or regulation or order has been enacted, adopted or issued by any
         governmental agency which prevents the issuance of the Securities,
         prevents or suspends the use of the preliminary offering memorandum or
         the Offering Memorandum or suspends the sale of the Securities in any
         jurisdiction referred to in Section 4(e) hereof; no injunction,
         restraining order or order of any nature by a Federal or state court of
         competent jurisdiction has been issued with respect to the Company, the
         Holding Company or any of the Affiliated Companies which would prevent
         the issuance of the Securities, prevent or suspend the use of the
         preliminary offering memorandum or the Offering Memorandum or suspend
         the sale of the Securities in any jurisdiction referred to in Section
         4(e) hereof; no action, suit or proceeding before any court or
         arbitrator or any governmental body, agency or official (domestic or
         foreign) is pending against or, to the knowledge of the Company,
         threatened against, the Company, the Holding Company or any of the
         Affiliated Companies which, if adversely determined, could reasonably
         be expected to (a) prevent the issuance of the Securities, (b) prevent
         the consummation of the transactions contemplated by the Acquisition
         Agreement, or (c) in any manner invalidate this Agreement, the
         Acquisition Agreement, the Registration Rights Agreement or the
         Indenture; and every request of any securities authority or agency of
         any jurisdiction for additional information (to be included in the
         preliminary offering memorandum or the Offering Memorandum or
         otherwise) that has been communicated to the Company has been complied
         with in all material respects or responded to in a manner acceptable to
         such securities authority.

                  (c)      The Securities that are being sold by the Company
         have been duly authorized for issuance and sale to the Initial
         Purchasers pursuant to this Agreement and, when issued and delivered by
         the Company pursuant to this Agr-

                                       16
   17
         eement against payment of the consideration set forth herein, will have
         been duly executed by the Company and the Guarantors; when the
         Securities are issued, authenticated and delivered in accordance with
         the Indenture and paid for in accordance with the terms of this
         Agreement, the Securities issued by the Company or the Guarantors, as
         applicable, will constitute valid and legally binding obligations of
         the Company and the Guarantors, as applicable, enforceable against the
         Company and the Guarantors, as applicable, in accordance with their
         terms and entitled to the benefits of the Indenture, subject to
         applicable bankruptcy, insolvency, reorganization, moratorium,
         fraudulent transfer and other laws affecting creditors' rights and
         remedies generally and to general principles of equity (regardless of
         whether enforcement is sought in a proceeding at law or in equity); the
         Securities and the capital stock of the Company conform in all material
         respects to the statements relating thereto in the Offering Memorandum;
         and the issuance and sale of the Securities by the Company will not be
         subject to preemptive or other similar rights.

                  (d)      Each of the Transaction Agreements has been or, as of
         the Closing Date will have been, duly authorized and validly executed
         and delivered by the Company, the Affiliated Companies and the
         Guarantors (to the extent each is a party thereto), and, assuming due
         execution by you and the other parties thereto, constitutes a valid and
         legally binding agreement of the Company, the Affiliated Companies and
         the Guarantors (to the extent each is a party thereto), enforceable
         against the Company, the Affiliated Companies and the Guarantors (to
         the extent each is a party thereto) in accordance with its terms
         subject to applicable bankruptcy, insolvency, reorganization,
         moratorium, fraudulent transfer and other laws affecting creditors'
         rights and remedies generally and to general principles of equity
         (regardless of whether enforcement is sought in a proceeding at law or
         in equity).

   18
                  (e)      The execution and delivery of the Transaction
         Agreements and the consummation of the Transactions do not and on the
         Closing Date will not (i) conflict with or result in a breach or
         violation of any of the respective charter or bylaws of the Company,
         the Affiliated Companies or the Holding Company or of any of the terms
         or provisions thereof as in effect on such respective dates, or (ii)
         constitute a default or cause an acceleration of any obligation under
         or result in the imposition or creation of (or the obligation to create
         or impose) a Lien (as hereinafter defined) with respect to, any of the
         respective charters or by-laws of the Company, the Affiliated Companies
         or the Holding Company or any material bond, note, debenture or other
         evidence of indebtedness or any indenture, mortgage, deed of trust or
         other material contract lease, or other instrument except for any such
         bond, note, debenture or other evidence of indebtedness or any
         indenture, mortgage, deed of trust or other material contract lease or
         other instrument which will be satisfied in full or terminated on or
         prior to the Closing Date to which the Company, the Holding Company or
         any of the Affiliated Companies is a party or by which any of them is
         bound, or to which any of the property or assets of the Company, the
         Holding Company or any of the Affiliated Companies is or may be
         subject, except for any such violation or default which, individually
         or in the aggregate, would not have a material adverse effect on the
         financial condition or results of operations or business of the Company
         and ARP, taken as a whole (a "Material Adverse Effect") and except for
         Liens in respect of the Securities and Liens to secure indebtedness
         incurred pursuant to the New Credit Facility, or (iii) contravene any
         order of any court or governmental agency or authority having
         jurisdiction over the Company, the Holding Company or any of the
         Affiliated Companies or any of their respective properties entered in
         any proceeding to which the Company, the Holding Company or any of the
         Affiliated Companies was or is a party or by which any of them is bound
         or vio-

                                       18
   19
         late or conflict with any applicable Federal, state or local law, rule,
         administrative regulation or ordinance or administrative or court
         decree applicable to the Company, the Holding Company or any of the
         Affiliated Companies or their respective properties except for such
         defaults, accelerations or contraventions that individually or in the
         aggregate would not have a Material Adverse Effect.

                  (f)      The Company has applied to have the Securities
         designated as PORTAL securities in accordance with the rules and
         regulations of the NASD.

                  (g)      Upon consummation of the Transactions, except for
         interests in Hambrose Leasing - III, Limited Partnership, Hambrose
         Leasing IV, Limited Partnership and Charterhouse Capital Associates,
         L.P., the only entity in which the Company will have an equity or other
         ownership interest will be ARP. The Company and ARP have been duly
         organized, each is validly existing as a corporation in good standing
         under the laws of its state of incorporation or organization and has
         full corporate power and authority to carry on its business as it is
         currently being conducted and as it will be conducted after the
         Acquisition. Each of the Company and ARP has the requisite corporate
         power and authority to own, lease and operate its properties, and each
         is duly qualified and is in good standing as a foreign corporation (or
         other entity) authorized to do business in each jurisdiction in which
         the nature of its business or its ownership or leasing of property
         requires such qualification except where the failure to be so qualified
         would not, individually or in the aggregate, have a Material Adverse
         Effect.

                  (h)      Each of the Company and the Guarantors has the
         requisite corporate power and authority to authorize the offering of
         the Securities and to execute, deliver and perform its obligations
         under each of the Transaction Agreements to which it is a party and to
         issue,

                                       19
   20
         sell and deliver the Securities being issued by such issuer.

                  (i)      All of the issued and outstanding shares of capital
         stock of ARP have been duly authorized and validly issued, and, on the
         Closing Date and after the Natur-Pharma II Merger, will be owned
         directly by the Company. All such shares in ARP are fully paid and
         non-assessable, and on the Closing Date, will be owned by the Company
         free and clear of any security interest, mortgage, pledge, claim, lien,
         encumbrance or adverse interest of any nature (each, a "Lien") other
         than Liens securing indebtedness under or granted in connection with
         the New Credit Facility. As of the Closing Date, there will be no
         outstanding subscriptions, rights, warrants, options, calls,
         convertible or exchangeable securities, commitments of sale, or Liens
         related to or entitling any person to purchase or otherwise to acquire
         any shares of the capital stock of ARP.

                  (j)      The authorized, issued and outstanding capital stock
         of the Company will be, as of the Closing Date, as set forth in the
         Offering Memorandum under "Capitalization"; all the shares of issued
         and outstanding capital stock of the Company have been duly authorized
         and validly issued and are fully paid, nonassessable and not subject to
         any preemptive or similar rights and all of the outstanding shares of
         capital stock of, or other ownership interests in, the Company will be
         on the Closing Date owned directly by the Holding Company, free and
         clear of all Liens other than Liens securing indebtedness to be
         incurred under the New Credit Facility.

                  (k)      Other than as disclosed in the Offering Memorandum,
         there is no action, suit or proceeding before or by any court or
         governmental agency or body, domestic or foreign, pending against the
         Company, the Affiliated Companies or the Holding Company which would be
         required to be disclosed in the Offering Memorandum if the Offering
         Memorandum were a pro-

                                       20
   21
         spectus contained in a registration statement on Form S-1 under the
         1933 Act, or which could reasonably be expected to have a Material
         Adverse Effect, or materially and adversely to affect the performance
         of the Company's or the Guarantors' obligations pursuant to this
         Agreement, the Registration Rights Agreement or the Indenture or the
         Company's obligations pursuant to the transactions contemplated hereby
         or thereby and, to the Company's knowledge, no such proceedings are
         contemplated or threatened.

                  (l)      Except as would not, individually or in the
         aggregate, have a Material Adverse Effect, neither the Company, the
         Affiliated Companies nor the Holding Company is in violation of any
         Federal, state, local and foreign laws and regulations relating to
         pollution or protection of human health or the environment (including,
         without limitation, ambient air, surface water, ground water, land
         surface or subsurface strata), including, without limitation, laws and
         regulations relating to emissions, discharges, releases or threatened
         releases of chemicals, pollutants, contaminants, wastes, toxic
         substances, hazardous substances, petroleum and petroleum products
         ("Materials of Environmental Concern"), or otherwise relating to the
         manufacture, processing, distribution, use, treatment, storage,
         disposal, transport or handling of Materials of Environmental Concern
         in connection with protection of human health or the environment
         (collectively, "Environmental Laws"), which violation includes, but is
         not limited to, noncompliance with any permits or other governmental
         authorizations required for the operation of the business of the
         Company, the Affiliated Companies or the Holding Company under
         applicable Environmental Laws, or noncompliance with the terms and
         conditions thereof, nor has the Company, the Affiliated Companies or
         the Holding Company received any communication (written or oral),
         whether from a governmental authority, citizens group, employee or
         otherwise, that alleges that the Company, the Affiliated Companies or
         the Holding Company

                                       21
   22
         is in violation and there are no circumstances, either past, present or
         that are reasonably foreseeable, that will or could reasonably be
         expected to lead to such violation in the future. In addition, except
         as disclosed in the preliminary offering memorandum or the Offering

         Companies or the Holding Company has retained or assumed either
         contractually or by operation of law.

         Federal, state or local law relating to employment and employment
         practices, discrimination in the hiring, promotion or pay of employees
         nor any applicable wage or hour laws, except for any such violation
         which, individually or in the aggregate, would not result in a Material
         Adverse Effect. There is (A) no significant unfair labor practice
         complaint pending against the Company, the Affiliated Companies or the
         Holding Company or, to the knowledge of the Company, the Affiliated
         Companies or the Holding Company, threatened against any of them,
         before the National Labor Relations Board or any state or local labor
         relations board, and no significant grievance or significant
         arbitration proceeding arising out of or under any collective
         bargaining agreement is pending against the Company, the Affiliated
         Companies or the Guarantors or, to the knowledge of the Company, the
         Affiliated Companies or the Holding Company, threatened against any of
         them, (B) no labor strike, dispute, slowdown or stoppage ("Labor
         Dispute") in which the Company, the Affiliated Companies or the Holding
         Company is involved nor, to the knowledge of the Company, the
         Affiliated Companies or the Holding Company, is any Labor Dispute
         imminent, other than routine disciplinary and grievance matters, each

         Company, no union organizing activities are taking place, except (with
         respect to any matter specified in clause (A), (B) or (C) above, singly
         or in the aggregate) such as would not have a Material Adverse Effect.

                  (n)      Subject to Liens securing indebtedness to be incurred
         under the New Credit Facility or disclosed in the Offering Memorandum,
         including capitalized leases, the Company and each of the Affiliated
         Companies has good and marketable title, free and clear of all Liens,
         to all property and assets described in the Offering Memorandum as
         being owned by it excluding any Liens that would not have a Material
         Adverse Effect. All leases to which the Company or any of the
         Affiliated Companies is a party are valid and binding and no default by
         the Company or any Subsidiary or, to the Company's knowledge, any other
         party has occurred or is continuing thereunder, except for any such
         defaults which, individually or in the aggregate, would not result in a
         Material Adverse Effect, and the Company and the Affiliated Companies
         enjoy possession under all such leases to which any of them is a party
         as lessee with such exceptions as do not materially interfere with the
         use made by the Company or the Affiliated Companies.

         maintains insurance covering their properties, operations, personnel
         and businesses, including without limitation product liability
         insurance. Neither the Company nor any of the Affiliated Companies has
         received written notice from any insurer or agent of such insurer that
         substantial capital improvements or other similar expenditures will
         have to be made in order to continue such insurance. All such insurance
         is outstanding and duly in force on the date hereof and will be
         outstanding and duly in force on the Closing Date.

                  (p)      The firm of accountants that has certified or shall
         certify the applicable combined financial statements of the Company and
         the Affiliated Companies included in the preliminary offering
         memorandum and the Offering Memorandum are independent public
         accountants with respect to the Company and its Subsidiaries, as
         required by the 1933 Act and the 1934

                                       24
   25
         Act. The combined financial statements of the Company, together with
         related notes, set forth in the preliminary offering memorandum and the
         Offering Memorandum (and any amendments or supplements thereto) comply
         as to form in all material respects with the requirements of the 1933
         Act and the 1934 Act and fairly present the combined financial position
         of the Company and the Affiliated Companies at the respective dates
         indicated and the results of their operations and their cash flows for
         the respective periods indicated, in accordance with generally accepted
         accounting principles in the United States of America consistently
         applied throughout such periods. The pro forma financial statements,
         together with related notes, set forth under the caption "Unaudited Pro
         Forma Condensed Consolidated Financial Data" in the preliminary
         offering memorandum and the Offering Memorandum have been prepared on a
         basis consistent with such historical statements, except for the pro
         forma adjustments specified therein, and give effect to assumptions
         made on a reasonable basis and present fairly the transactions
         reflected thereby as indicated in the preliminary offering memorandum,
         the Offering Memorandum and the Transaction Agreements and comply as to
         form in all material respects with the applicable accounting
         requirements of rule 11-02 of Regulation S-X and the pro forma
         adjustments have been properly applied to the historical amounts in the
         compilation of those statements.

                  (q)      Except as contemplated by the preliminary offering
         memorandum and the Offering Memorandum, subsequent to the respective
         dates as of which information is given in the preliminary offering
         memorandum and the Offering Memorandum, (i) neither the Company nor any
         of the Affiliated Companies has incurred any liabilities or
         obligations, direct or contingent, which are material to the Company
         and the Affiliated Companies, taken as a whole, nor entered into any
         transaction not in the ordinary course of business that is material to
         the Company and the Affiliated Companies, taken as

                                       25
   26
         a whole, (ii) there has been no decision or judgment in any litigation
         to which the Company or any of the Affiliated Companies are a party
         materially adverse to the Company and any of the Affiliated Companies,
         taken as a whole, and (iii) there has been no material adverse change
         in the financial condition or in the results of operations or business
         of the Company and the Affiliated Companies, taken as a whole (any of
         the items set forth in clauses (i), (ii), or (iii), above, "Material
         Adverse Change").

                  (r)      All tax returns required to be filed by the Company
         and its Subsidiaries in any jurisdiction have been filed, other than
         those filings that are being contested in good faith, except where
         failure to so file would not have a Material Adverse Effect, and all
         taxes, including withholding taxes, penalties and interest,
         assessments, fees and other governmental charges due or claimed to be
         due from such entities have been paid other than those being contested
         in good faith and for which adequate reserves have been provided,
         except where failure to so pay would not have a Material Adverse
         Effect.

                  (s)      As of the Closing Date, the Company and the
         Guarantors will possess such licenses, certificates, authorizations,
         approvals, franchises, permits and other rights issued by local, state,
         Federal or foreign regulatory agencies or bodies (collectively,
         "Permits") as are necessary to own, lease and operate its respective
         properties and to conduct the businesses now conducted by them except
         where the failure to possess any such Permit would not have a Material
         Adverse Effect; as of the Closing Date, the Company and each of the
         Guarantors will have fulfilled and performed all of its material
         obligations with respect to such Permits and neither the Company nor
         the Guarantors will have received any notice of proceedings relating to
         the revocation or modification of any such Permit that is reasonably
         likely to have a Material Adverse Effect.

                                       26
   27
                  (t)      As of the Closing Date, each of the Company and the
         Guarantors will own or possess all patents, patent rights, licenses,
         inventions, copyrights, know-how (including trade secrets and other
         unpatented and/or unpatentable proprietary or confidential information,
         systems or procedures), trademarks, service marks and trade names
         (collectively, the "Intellectual Property") presently employed by it in
         connection with the businesses now operated by them, except where the
         failure to so own or possess would not, individually or in the
         aggregate, have a Material Adverse Effect, and neither the Company nor
         the Guarantors will have received any notice of infringement of or
         conflict with asserted rights of others with respect to any of the
         foregoing, except where such infringement or conflict would not
         individually, or in the aggregate, have a Material Adverse Effect. To
         the Company's knowledge, the use of the Intellectual Property in
         connection with the business and operations of the Company and the
         Guarantors does not infringe on the rights of any person, except where
         such infringement does not individually or in the aggregate have a
         Material Adverse Effect. The representations in this clause (t) exclude
         Intellectual Property matters with respect to any foreign country that
         has not accounted for more than 1% of the sales of the Company and the
         Affiliated Companies in either of the last 2 fiscal years.

                  (u)      The Company, the Holding Company and each of the
         Affiliated Companies maintains a system of internal accounting controls
         sufficient to provide reasonable assurance that (1) transactions are
         executed in accordance with management's general or specific
         authorizations; (2) transactions are recorded as necessary to permit
         preparation of financial statements in conformity with generally
         accepted accounting principles and to maintain asset accountability;
         (3) access to assets is permitted only in accordance with management's
         general or specific authorization; and (4) the recorded accountability
         for inventory assets is compared 

                                       27
   28
         with the existing inventory assets at reasonable intervals and
         appropriate action is taken with respect to any differences.

                  (v)      None of the Company, the Holding Company or any of
         the Affiliated Companies has, directly or indirectly, paid or delivered
         any fee, commission or other sum of money or item of property, however
         characterized, to any finder, agent, government official or other
         party, in the United States or any other country, which is in any
         manner related to the business or operations of the Company, the
         Holding Company and the Affiliated Companies which any of such entities
         knows or has reason to believe to have been illegal under any Federal,
         state or local laws of the United States or any other country having
         jurisdiction; and none of the Company, the Holding Company or any of
         the Affiliated Companies has participated, directly or indirectly, in
         any boycotts or other similar practices in contravention of law
         affecting any of its actual or potential customers.

                  (w)      As of the Closing Date, neither the Company nor any
         Guarantor is (i) an "investment company" or a company "controlled" by
         an "investment company" within the meaning of the Investment Company
         Act of 1940, as amended, or (ii) a "holding company" or a "subsidiary
         company" of a holding company, or an "affiliate" thereof within the
         meaning of the Public Utility Holding Company Act of 1935, as amended.

                  (x)      Except as disclosed in the preliminary offering
         memorandum or the Offering Memorandum, no holder of any security of the
         Company has any right to require registration of the Securities.

                  (y)      Assuming the accuracy of your representations
         contained in Section 3 hereof and your compliance with your agreements
         therein set forth, it is not necessary, in connection with the sale and
         delivery of the Securities to

                                       28
   29
         you and the offer and resale of the Securities by you, in each case in
         the manner contemplated by this Agreement and the Offering Memorandum,
         to register the Securities under the 1933 Act or to qualify the
         Indenture under the Trust Indenture Act of 1939, as amended, and the
         rules and regulations thereunder (collectively, the "TIA").

                  (z)      None of the Company, the Holding Company, any of the
         Affiliated Companies or any affiliate (as such term is defined in Rule
         501(b) under the 1933 Act) has, directly or through any agent, sold,
         offered for sale, solicited offers to buy or otherwise negotiated in
         respect of, any security (as defined in the 1933 Act) which is or will
         be integrated with the sale of the Securities in a manner that would
         require the registration of the Securities under the 1933 Act.

                  (aa)     None of the Company, the Holding Company or any of
         the Affiliated Companies and any officer, director or other person
         (other than you, as to whom the Company makes no representation) acting
         on its behalf has engaged, in connection with the offering of the
         Securities, in any form of general solicitation or general advertising,
         including but not limited to the methods described in Rule 502(c) under
         the 1933 Act.

                  (ab)     To the knowledge of the Company and the Guarantors,
         immediately after and after giving effect to the Offering, the
         Acquisition and the New Credit Facility, with respect to the Company on
         a consolidated basis, (i) the present fair salable value of its assets
         shall be more than the amount that will be required to pay its debts
         (including contingent and unliquidated debts) as they become absolute
         and matured, (ii) its assets, at a fair valuation, shall be greater
         than the sum of its debts (including contingent and unliquidated
         debts), (iii) it shall not be engaged in a business or transaction for
         which its remaining assets are unreasonably small in relation to such
         business or transaction, and (iv) it shall not intend to incur or
         believe that

                                       29
   30
         it will incur debts beyond its ability to pay as such debts become
         absolute and matured.

                  (ac)     The Indenture, as of the date hereof and at the
         Closing Date, will conform in all material respects to the requirements
         of the TIA applicable to an indenture which is qualified under the TIA.

                  (ad)     None of the proceeds of the sale of the Securities
         will be used, directly or indirectly, for the purpose of purchasing or
         carrying any margin security (as that term is defined in Regulations G
         and U of the Federal Reserve Board), for the purpose of reducing or
         retiring any indebtedness which was originally incurred to purchase or
         carry any margin security or for any other purpose which might cause
         any of the Securities to be considered a "purpose credit" within the
         meanings of Regulation G, T, U or X of the Board of Governors of the
         Federal Reserve System (the "Federal Reserve Board").

                  (ae)     Based on the representation of the Initial Purchasers
         set forth in Section 3(b)(vi) hereof, the execution and delivery of the
         Transaction Agreements and the consummation of the Transactions will
         not involve any non-exempt prohibited transaction within the meaning of
         Section 406 of ERISA or Section 4975 of the Internal Revenue Code of
         1986, as amended, or the rules, regulations and published
         interpretations promulgated thereunder (the "Code"). Neither the
         Company nor any of its ERISA Affiliates is a "party in interest" or a
         "disqualified person" except with respect to those employee benefit
         plans described in "Notice to Investors" in the Offering Memorandum.
         Except as disclosed in Schedule XV to the Stock Purchase Agreement, no
         condition exists or event or transaction has occurred in connection
         with any employee benefit plan that could result in the Company or any
         such ERISA Affiliate incurring any liability, fine or penalty that
         could, singly or in the aggregate, have a Material Adverse Effect. With
         respect to any employee pension benefit plan that is subject to Title
         IV of ERISA, except as adequately dis-

                                       30
   31
         closed in the Offering Memorandum, (i) the fair market value of the
         assets of such employee pension benefit plan equals or exceeds the
         present value of the liabilities of such pension plan (as determined in
         accordance with the actuarial methods and assumptions set forth in the
         latest actuarial report for such employee pension benefit plan), except
         where the failure to so equal or exceed would not, singly or in the
         aggregate, have a Material Adverse Effect and (ii) there exists no
         accumulated funding deficiency which would have, singly or in the
         aggregate, a Material Adverse Effect. The terms "employee benefit
         plan," "employee pension benefit plan" and "party in interest" shall
         have the meanings assigned to such terms in Section 3 of ERISA, the
         term "Affiliate" shall have the meaning assigned to such term in
         Section 407(d)(7) of ERISA, and the term "disqualified person" shall
         have the meaning assigned to such term in Section 4975 of the Code.

                  (af)     The Company has delivered to the Initial Purchasers
         true and correct copies of the Acquisition Agreement, and there have
         been no amendments, alterations, modifications or waivers thereto or in
         the exhibits or schedules thereto to which the Initial Purchasers shall
         have reasonably objected.

                  (ag)     Each certificate signed by any officer of the Company
         and delivered to the Initial Purchasers or counsel for the Initial
         Purchasers shall be deemed to be a representation and warranty by the
         Company to each Initial Purchaser as to the matters covered thereby to
         the extent expressly set forth therein.

                  (ah)     To the extent that any representation in Section 5 of
         this Agreement is qualified by reference to the preliminary offering
         memorandum, no such representation shall be deemed breached by reason
         of any misstatement or omission in such preliminary offering memorandum
         if and to the extent such misstatement or omission was corrected in the
         Offering Memorandum.

         6.       Indemnification.

                  (a)      Each of the Company and the Guarantors, jointly and
         severally, agrees to indemnify and hold harmless (i) each of the
         Initial Purchasers and (ii) each person, if any, who controls (within
         the meaning of Section 15 of the 1933 Act or Section 20 of the 1934
         Act) any of the Initial Purchasers (any of the persons referred to in
         this clause (ii) being hereinafter referred to as a "controlling
         person"), and (iii) the respective officers, directors, partners,
         employees, representatives and agents of any of the Initial Purchasers
         or any controlling person (any person referred to in clause (i), (ii)
         or (iii) may hereinafter be referred to as an "Indemnified Person") to
         the fullest extent lawful, from and against any and all losses, claims,
         damages, judgments, actions, costs, assessments, expenses and other
         liabilities (collectively, "Liabilities"), including, without
         limitation, and as incurred, reimbursement of all reasonable costs of
         investigating, preparing, pursuing or defending any claim or action, or
         any investigation or proceeding by any governmental agency or body,
         commenced or threatened, including the reasonable fees and expenses of
         counsel to any Indemnified Person directly or indirectly caused by,
         related to, based upon, arising out of or in connection with any untrue
         statement or alleged untrue statement of a material fact contained in
         the Offering Memorandum (or any amendment or supplement thereto), or
         any preliminary offering memorandum, or any omission or alleged
         omission to state therein a material fact required to be stated therein
         or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading, except
         insofar as such Liabilities are caused by (i) an untrue statement or
         omission or alleged untrue statement or omission that is made in
         reliance upon and in conformity with information relating to any of the
         Initial Purchasers furnished in writing to the Company by any of the
         Initial Purchasers expressly for use in the Offering Memorandum (or any
         amendment or supplement thereto) or any preliminary offering memorandum
         or (ii) an untrue or 
                                       32
   33
         alleged untrue statement contained in or omission or alleged omission
         from the preliminary offering memorandum if a copy of the Offering
         Memorandum (as then amended or supplemented) was not delivered by or on
         behalf of the Initial Purchasers to the person asserting the claim or
         action, if required by law to have been so delivered by the Initial
         Purchasers seeking indemnification and the untrue statement or alleged
         statement or omission or alleged omission from such preliminary
         offering memorandum was corrected in the Offering Memorandum.
         Notwithstanding the foregoing, in the event that it is finally
         determined by a court of competent jurisdiction that indemnification
         under this Section 6(a) is not available to an Indemnified Person,
         expenses paid in advance of the final disposition of such claim,
         action, investigation or proceeding shall be repaid to the Company by
         such Indemnified Person. The Company and the Guarantors shall notify
         you promptly of the institution, threat or assertion of any claim,
         proceeding (including any governmental investigation) or litigation in
         connection with the matters addressed by this Agreement which involves
         the Company, the Guarantors or an Indemnified Person.

                  (b)      In case any action or proceeding (for all purposes of
         this Section 6 including any governmental investigation) shall be
         brought or asserted against any of the Indemnified Persons with respect
         to which indemnity may be sought against the Company or any of the
         Guarantors, the applicable Initial Purchaser with respect to such
         Indemnified Person shall promptly notify the Company in writing
         (provided, that the failure to give such notice shall not relieve the
         Company or such Guarantor of its obligations pursuant to this Agreement
         except to the extent that the Company or any Guarantor is materially
         prejudiced or forfeits rights or defenses by reason of such failure).
         Upon receiving such notice, the Company or such Guarantor shall be
         entitled to participate in any such action or proceeding and to assume,
         at its sole expense, the defense thereof, with counsel reasonably
         satisfactory to such Indemnified Person (who shall not, except with

                                       33
   34
         the consent of the Indemnified Person, be counsel to the Company or to
         the Guarantors or any affiliate thereof) and, after written notice from
         the Company to such Indemnified Person of its election to so assume the
         defense thereof reasonably promptly after receipt of the notice from
         the Indemnified Person of such action or proceeding, the Company and
         such Guarantor shall not be liable to such Indemnified Person hereunder
         for legal expenses of other counsel subsequently incurred by such
         Indemnified Person in connection with the defense thereof, other than
         costs of investigation, unless (i) the Company and such Guarantor agree
         to pay such fees and expenses, or (ii) the Company fails promptly to
         assume such defense or fails to employ counsel reasonably satisfactory
         to such Indemnified Person, or (iii) the named parties to any such
         action or proceeding (including any impleaded parties) include both
         such Indemnified Person and the Company or such Guarantor or any
         affiliate of the Company or such Guarantor, and either (x) there may be
         one or more legal defenses available to such Indemnified Person that
         are different from or additional to those available to the Company or
         such Guarantor or such affiliate of the Company or such Guarantor or
         (y) the Indemnified Person shall have been advised by counsel that a
         conflict may exist between such Indemnified Person and the Company or
         such Guarantor or such affiliate of the Company or such Guarantor. In
         the event of any of clause (i), (ii) or (iii) of the immediately
         preceding sentence, if such Indemnified Person notifies the Company in
         writing, the Company shall not have the right to assume the defense
         thereof and such Indemnified Person shall have the right to employ its
         own counsel in any such action and the fees and expenses of such
         counsel shall be paid, as incurred, by the Company, subject to the
         provisions hereof, it being understood, however, that the Company shall
         not, in connection with any one such action or proceeding or separate
         but substantially similar or related actions or proceedings arising out
         of the same general allegations or circumstances, be liable for the
         fees and expenses of more than one separate firm of attorneys (in
         addition to any

                                       34
   35
         local counsel) at any time for the Indemnified Persons. The Company and
         the Guarantors shall be liable for any settlement of any such action or
         proceeding effected with the Company's prior written consent, which
         consent will not be unreasonably withheld, and the Company and each
         Guarantor agrees to indemnify and hold harmless any Indemnified Person
         from and against any Liabilities by reason of any settlement of any
         action effected with the prior written consent of the Company. The
         Company and the Guarantors agree to be liable for any settlement of any
         proceeding effected without the Company's prior written consent if (i)
         such settlement is entered into more than 10 business days after
         receipt by the Company of the aforesaid request for payment in respect
         of an indemnification obligation pursuant hereto and (ii) the Company
         shall not have reimbursed the Indemnified Person in accordance with
         such request prior to the date of such settlement. The Company and the
         Guarantors shall not, without the prior written consent of each
         Indemnified Person, settle or compromise or consent to the entry of any
         judgment in or otherwise seek to terminate any pending or threatened
         action, claim, litigation or proceeding in respect of which
         indemnification or contribution may be sought pursuant hereto (whether
         or not any Indemnified Person is a party thereto), unless such
         settlement, compromise, consent or termination includes an
         unconditional release of each Indemnified Person from all Liabilities
         arising out of such action, claim, litigation or proceeding.

                  (c)      Each of the Initial Purchasers agrees, severally and
         not jointly, to indemnify and hold harmless the Company and the
         Guarantors and their respective directors, officers and any person
         controlling (within the meaning of Section 15 of the 1933 Act or
         Section 20 of the 1934 Act) the Company or the Guarantors and the
         officers, directors, partners, employees, representatives and agents of
         each such person, to the same extent as the foregoing indemnity from
         the Company and the Guarantors to each of the Indemnified Persons, but
         only with respect to claims and actions based on information relating
         to such Ini-

                                       35
   36
         tial Purchaser in the Offering Memorandum that is in conformity with
         information furnished in writing by such Initial Purchaser expressly
         for use in the Offering Memorandum. In case any action or proceeding
         (including any governmental investigation) shall be brought or asserted
         against the Company, the Guarantors or any of their respective
         directors or officers, or any such controlling person based on any
         preliminary offering memorandum or the Offering Memorandum in respect
         of which indemnity may be sought against any Initial Purchaser pursuant
         to the foregoing sentence, such Initial Purchaser shall have the rights
         and duties given to the Company and the Guarantors by Section 6(b)
         hereof (except that if the Company shall have assumed the defense
         thereof, such Initial Purchaser may but shall not be required to employ
         separate counsel therein and participate in the defense thereof but the
         fees and expenses of such counsel shall be at the expense of such
         Initial Purchaser), and the Company and the Guarantors, their
         respective directors or officers, and each such controlling person
         shall have the rights and duties given to the Indemnified Person by
         Section 6(b) hereof.

                  (d)      If the indemnification provided for in this Section 6
         is finally determined by a court of competent jurisdiction to be
         unavailable to an indemnified party in respect of any Liabilities
         referred to herein, then each indemnifying party, in lieu of
         indemnifying such indemnified party, shall contribute to the amount
         paid or payable by such indemnified party as a result of such
         Liabilities (i) in such proportion as is appropriate to reflect the
         relative benefits received by the indemnifying party on the one hand
         and the indemnified party on the other hand from the offering of the
         Securities or (ii) if the allocation provided by clause (i) above is
         not permitted by applicable law, in such proportion as is appropriate
         to reflect not only the relative benefits referred to in clause (i)
         above but also the relative fault of the indemnifying parties and the
         indemnified party, as well as any other relevant equitable
         considerations. The relative benefits received by the Company and the

                                       36
   37
         Guarantors, on the one hand, and any of the Initial Purchasers, on the
         other hand, shall be deemed to be in the same proportion as the total
         proceeds from the offering (net of discounts and commissions but before
         deducting expenses) received by the Company bear to the total discounts
         and commissions received by such Initial Purchaser, in each case as set
         forth in the table on the cover page of the Offering Memorandum. The
         relative fault of the Company and the Guarantors, and the Initial
         Purchasers, shall be determined by reference to, among other things,
         whether the untrue or alleged untrue statement of a material fact or
         the omission or alleged omission to state a material fact related to
         information supplied by the Company, the Guarantors or the Initial
         Purchasers and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission. The indemnity and contribution obligations set forth herein
         shall be in addition to any liability or obligation such party may
         otherwise have to any indemnified party.

                  The Company, the Guarantors and the Initial Purchasers agree
that it would not be just and equitable if contribution pursuant to Section 6(d)
hereof were determined by pro rata allocation (even if the Initial Purchasers
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to in the immediately preceding paragraph. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, judgments,
liabilities or expenses referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6, none of the Initial Purchasers (and its related
Indemnified Persons) shall be required to contribute, in the aggregate, any
amount in excess of the amount by which the total underwriting discount
applicable to the Securities purchased by such Initial Purchaser exceeds the
amount of any damages or liabilities which such Initial Purchaser has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or al-

                                       37
   38
leged omission. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The Initial
Purchasers' obligations to contribute pursuant to Section 6(d) hereof are
several in proportion to the respective principal amount of Securities purchased
by each of the Initial Purchasers hereunder and not joint.

         7.       Conditions of Initial Purchasers' Obligations. The several
obligations of the Initial Purchasers to purchase the Securities under this
Agreement are subject to the satisfaction of each of the following conditions:

                  (a)      All the representations and warranties of the Company
         and the Guarantors contained in this Agreement shall be true and

         and the Guarantors shall have performed or complied in all material
         respects with all of their obligations and agreements herein contained
         and required to be performed or complied with at or prior to the
         Closing Date.

                  (b)      The Offering Memorandum shall have been printed and
         copies distributed to the Initial Purchasers as promptly as reasonably
         practicable following the date of this Agreement or at such other date
         and time as to which you may agree.

                  (c)      No action shall have been taken, and no statute,
         rule, regulation or order shall have been enacted, adopted or issued,
         by any governmental agency which would, as of the Closing Date, prevent
         the issuance of the Securities; and no injunction, restraining order or
         order of any nature by a Federal or state court of competent
         jurisdiction shall have been issued as of the Closing Date which would
         prevent the issuance of the Securities, and on the Closing Date no
         action, suit or proceeding shall be pending against, or, to the
         knowledge of the Company, threatened against the Company or any of its
         Subsidiaries before any court or arbitrator or any

                                       38
   39
         governmental body, agency or official which, if adversely determined,
         would prevent the issuance of the Securities or would have a Material
         Adverse Effect; and no stop order suspending the sale of the Securities
         in any jurisdiction referred to in Section 4(e) hereof shall have been
         issued and no proceeding for that purpose shall have been commenced or
         shall be pending or, to the knowledge of the Company, threatened.

                  (d)      (i) Except as otherwise specifically contemplated in
         the Offering Memorandum, since the date hereof, there shall not have
         been any Material Adverse Change; (ii) since the date of the latest
         balance sheet included in the Offering Memorandum, there shall not have
         been any material change in the capital stock or long-term debt, or
         material increase in short-term debt, of the Company or any of its
         consolidated Subsidiaries taken as a whole (excluding the repayment of
         certain indebtedness to David and Jean Blechman); and (iii) the Company
         and its Subsidiaries shall have no liability or obligation, direct or
         contingent, which is material to the Company and its Subsidiaries,
         taken as a whole, in each case other than those reflected in the
         Offering Memorandum.

                  (e)      The Company, the Guarantors and the Trustee shall
         have entered into the Indenture and you shall have received
         counterparts, conformed as executed, thereof.

                  (f)      The Company and the Guarantors shall have entered
         into the Registration Rights Agreement and you shall have received
         counterparts, conformed as executed, thereof.

                  (g)      The Securities shall have been designated PORTAL
         securities in accordance with the rules and regulations adopted by the
         NASD relating to trading in the PORTAL market.

                  (h)      You shall have received a certificate of the Company,
         dated the Closing Date, executed on behalf of the Company by the
         President or any Vice President, and a principal financial

                                       39
   40
         or accounting officer of the Company, confirming, as of the Closing
         Date, the matters set forth in paragraphs (a), (c) and (d) of this
         Section 7.

                  (i)      On or prior to the Closing Date, (i)(A) the
         Acquisition and the transactions contemplated thereby shall have been
         consummated, and (b) the Company shall have entered into the Bank
         Agreements and all conditions precedent to the effectiveness thereof
         shall have been satisfied or waived, (ii) such transactions described
         in the foregoing clause (i) shall continue to be in full force and
         effect in accordance with the terms thereof, and (iii) the Company
         shall have provided to each of the Initial Purchasers and counsel to
         the Initial Purchasers copies of all material closing documents
         delivered to the parties relating to the Acquisition and the Bank
         Agreements (including but not limited to legal opinions relating
         thereto).

                  (j)      On the Closing Date, you shall have received:

                           i)       an opinion (in a form reasonably
satisfactory to you and your counsel), dated the Closing Date, of Kramer, Levin,
Naftalis & Frankel ("Kramer, Levin"), counsel for the Company and the
Guarantors, to the effect that:

                                    a)       assuming the accuracy of the
                           representations and warranties of the Company
                           contained in Section 5 and your representations and
                           warranties and assuming compliance by you with your
                           covenants contained in Section 4 of this Agreement,
                           the offering of the Securities by you and the
                           issuance and sale of the Securities to you, in each
                           case in the manner contemplated in the Offering
                           Memorandum and as provided in this Agreement, are
                           exempt from the registration requirements of the 1933
                           Act and it is not necessary to qualify the Indenture
                           under the TIA;

                                    b)       the Notes, when executed by the
                           Company and authenticated by the

                                       40
   41

                           Indenture, and delivered to and paid for in
                           accordance with the terms of this Agreement, will
                           constitute legal, valid and binding obligations of
                           the Company, enforceable against the Company in
                           accordance with their terms and entitled to the
                           benefits of the Indenture, subject to applicable
                           bankruptcy, insolvency, fraudulent conveyance,
                           reorganization, moratorium and similar laws affecting
                           creditors' rights and remedies generally and to
                           general principles of equity (regardless of whether
                           enforcement is sought in a proceeding at law or in
                           equity) and except to the extent that a waiver of
                           rights under any usury laws may be unenforceable;

                                    c)       the Guarantees, when executed by
                           the Guarantors in accordance with the terms of the
                           Indenture, will constitute legal, valid and binding
                           obligations of the Guarantors, enforceable against
                           the Guarantors in accordance with their terms and
                           entitled to the benefits of the Indenture, subject to
                           applicable bankruptcy, insolvency, fraudulent
                           conveyance, reorganization, moratorium and similar
                           laws affecting creditors' rights and remedies
                           generally and to general principles of equity
                           (regardless of whether enforcement is sought in a
                           proceeding at law or in equity) and except to the
                           extent that a waiver of rights under any usury laws
                           may be unenforceable;

                                    d)       the Securities and the Indenture
                           conform as to legal matters, in all material respects
                           to the descriptions thereof contained in the Offering
                           Memorandum; and

                                    e)       neither the Company nor any of the

                           submitted to such counsel for review do not give rise
                           to a substantial expectation that enforcement action
                           would be initiated against those products.

although such counsel has not undertaken to investigate or verify independently,
and is not passing upon and does not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Offering Memorandum
(except to the extent expressly referred to in clauses (i)(d) and (iii)(h)
above), during the course of such counsel's participation in conferences with
officers and other representatives of the Company, representatives of the
independent public accountants for the Company and you, at which the contents of
the Offering Memorandum were discussed, no facts have come to the attention of
such counsel which cause it to believe that (except for financial statements,
notes thereto, financial statements schedules, other financial data included
therein or information derived therefrom as to which such counsel need not
express any belief) the Offering Memorandum, as of the date thereof and as of
the date hereof, contained an untrue statement of a material fact or omitted to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

                  In rendering such opinions, such counsel may rely, as to
matters of fact, to the extent such counsel deems proper, on certificates of
responsible officers and other representatives of the Company, certificates of
public officials, and certificates or other written statements of officers of
departments of various jurisdictions having custody of documents respecting the
corporate existence or good standing of the Company and the Guarantors provided
that copies of any such statements or certificates shall be delivered or
otherwise made available to your counsel.

                                    (k)      You shall have received an opinion,
                           as to certain of the matters set forth above, dated

                           satisfactory to you. In rendering such opinion,
                           Skadden Arps may rely, as to matters of Utah law, to
                           the extent such counsel deems proper on the opinions
                           set forth in paragraph (j)(ii) above.

                           Transactions will not render the Company insolvent,
                           leave the Company with inadequate or unreasonably
                           small capital or result in the Company incurring
                           indebtedness beyond its ability to repay as such
                           indebtedness matures.

                                    (m)      You shall have received letters on

                           former, based on limited procedures), in form and

                           Offering Memorandum.

                                    (n)      Skadden Arps shall have been
                           furnished with such documents and opinions, in
                           addition to those set forth above, as they may
                           reasonably require for the purpose of enabling them
                           to review or pass upon the matters referred to in
                           this Section 7 and in order to evidence the accuracy,
                           completeness or satisfaction in all material respects
                           of any of the representations, warranties or
                           conditions herein contained.

                                    (o)      Prior to the Closing Date, the
                           Company shall have furnished to you such further
                           information, certificates and documents as you may
                           reasonably request.

                                    (p)      The Initial Purchasers shall have
                           been furnished with a copy of the opinions delivered
                           on behalf of GEI, the Company, ARP and the Holding
                           Company in connection with the Acquisition and the
                           Bank Agreements, which opinions shall expressly state
                           that the Initial Purchasers are justified in relying
                           upon the opinions therein.

                  All opinions, certificates, letters and other documents
required by this Section 7 to be delivered by the

                                       48
   49
Company and the Guarantors will be in compliance with the provisions hereof only
if they are reasonably satisfactory in form and substance to you. The Company
will furnish the Initial Purchasers with such conformed copies of such opinions,
certificates, letters and other documents as they shall reasonably request.

         8.       Defaults. If on the Closing Date, any of the Initial
Purchasers shall fail or refuse to purchase Securities which it has agreed to
purchase hereunder on such date, and the aggregate principal amount of such
Securities that such defaulting Initial Purchaser(s) agreed but failed or
refused to purchase does not exceed 10% of the total principal amount of such
Securities that all of the Initial Purchasers are obligated to purchase on such
Closing Date, each non-defaulting Initial Purchaser shall be obligated to
purchase the amount of the Securities that such defaulting Initial Purchaser(s)
agreed but failed or refused to purchase on such date; provided that in no event
shall the number of Securities that any Initial Purchaser has agreed to purchase
pursuant to Section 1 hereof be increased pursuant to this Section 8 by an
amount in excess of one-ninth of such number of Securities, without the written
consent of such Initial Purchaser. If, on the Closing Date, any of the Initial
Purchasers shall fail or refuse to purchase Securities in an aggregate principal
amount that exceeds 10% of such total principal amount of the Securities and
arrangements satisfactory to the other Initial Purchaser(s) and the Company for
the purchase of such Securities are not made within 48 hours after such default,
this Agreement shall terminate without liability on the part of the
non-defaulting Initial Purchaser(s), the Company or the Guarantors, except as
otherwise provided in Section 9 hereof. In any such case that does not result in
termination of this Agreement, the Initial Purchasers and the Company may agree
to postpone the Closing Date for not longer than seven days, in order that the
required changes, if any, in the Offering Memorandum or any other documents or
arrangements may be effected. Any action taken under this paragraph shall not
relieve a defaulting Initial Purchaser from liability in respect of any default
by such Initial Purchaser under this Agreement.

         9.       Effective Date of Agreement and Termination. This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

                  This Agreement may be terminated at any time on or prior to
the Closing Date by you by notice to the Company if any of the following has
occurred: (i) subsequent to the date of this Agreement, any Material Adverse
Change occurs, which, in your judgment, makes it impracticable or inadvisable to
market the Securities in the manner contemplated in the Offering Memorandum or
to enforce contracts for sale of the Securities, (ii) any outbreak or escalation
of hostilities or other national or international calamity or crisis or material
adverse change in the financial markets of the United States or elsewhere, or
any other substantial national or international calamity or emergency if the
effect of such outbreak, escalation, calamity, crisis or emergency would, in
your judgment, make it impracticable or inadvisable to market the Securities or
to enforce contracts for the sale of the Securities, (iii) any suspension or
limitation of trading generally in securities on the New York Stock Exchange,
the American Stock Exchange, the Nasdaq National Market System or in the
over-the-counter markets or any setting of minimum prices for trading on such
exchange or markets, (iv) any declaration of a general banking moratorium by
either Federal or New York authorities, (v) the taking of any action by any
Federal, state or local government or agency in respect of its monetary or
fiscal affairs that in your judgment has a material adverse effect on the
financial markets in the United States, and would, in your judgment, make it
impracticable or inadvisable to market the Securities or to enforce contracts
for the sale of the Securities, (vi) the enactment, publication, decree, or
other promulgation of any Federal or state statute, regulation, rule or order of
any court or other governmental authority which would, in your judgment, have a
Material Adverse Effect, or (vii) the Securities or any securities of the
Company shall have been downgraded or placed on any "watch list" for possible
downgrading by any nationally recognized statistical rating organization,
provided, that in the case of such "watch list" placement, termination shall be
permitted only if such placement would, in the judgment of any Initial
Purchaser, make it impracticable or inadvisable to market the Securities or to
enforce contracts for the sale of the Securities or materially impair the
investment quality of the Securities.

                  The indemnities and contribution provisions and the other
agreements, representations and warranties of the Company, the Guarantors, their
respective officers and directors and the Initial Purchasers set forth in or
made

                                       50
   51
pursuant to this Agreement shall remain operative and in full force and effect,
and will survive delivery of and payment for the Securities, regardless of (i)
any investigation, or statement as to the results thereof, made by or on behalf
of any of the Initial Purchasers or by or on behalf of the Company or the
Guarantors, its officers or directors or any controlling person thereof, (ii)
acceptance of the Securities and payment for them hereunder and (iii)
termination of this Agreement.

                  If this Agreement shall be terminated by the Initial
Purchasers pursuant to clause (i) or (vii) of the second paragraph of this
Section 9 or because of the failure or refusal on the part of the Company or the
Guarantors to comply with the terms or to fulfill any of the conditions of this
Agreement, the Company and the Guarantors agree to reimburse you for all
out-of-pocket expenses incurred by you. Notwithstanding any termination of this
Agreement, the Company shall be liable for all expenses which it has agreed to
pay pursuant to Section 4(h) hereof.

                  Except as otherwise provided, this Agreement has been and is
made solely for the benefit of and shall be binding upon the Company, the
Guarantors, the Initial Purchasers, any Indemnified Person referred to herein
and their respective successors and assigns, all as and to the extent provided
in this Agreement, and no other person shall acquire or have any right under or
by virtue of this Agreement. The terms "successors and assigns" shall not
include a purchaser of any of the Securities from any of the Initial Purchasers
merely because of such purchase. Notwithstanding the foregoing, it is expressly
understood and agreed that each purchaser of the Securities from you is intended
to be a beneficiary of the Company's covenants contained in the Registration
Rights Agreement to the same extent as if the Securities were sold and those
covenants were made directly to such purchaser by the Company, and each such
purchaser shall have the right to take action against the Company to enforce,
and obtain damages for any breach of, those covenants.
