(collectively, the “Prepetition Lenders”) in an aggregate principal amount of $30,154,082.65, plus interest and other amounts due thereon, according to proofs of claim filed by the Prepetition Lenders in the Biovest Bankruptcy Cases (the “Prepetition Debt”);

(c) Other Terms. Any capitalized terms used in this Agreement and defined in the UCC shall have the meaning given therein, unless otherwise defined herein.

(d) Rules of Construction. All Schedules, Addenda, Annexes and Exhibits hereto or expressly identified to this Agreement are incorporated herein by reference and taken together with this Agreement constitute but a single agreement. The words “herein”, “hereof” and “hereunder” or other words of similar import refer to this Agreement as a whole, including the Exhibits, Addenda, Annexes and Schedules thereto, as the same may be from time to time amended, modified, restated or supplemented in accordance with the terms of this Agreement, and not to any particular section, subsection or clause contained in this Agreement. Wherever from the context it appears appropriate, each term stated in either the singular or the plural shall include the singular and the plural, and pronouns stated in the masculine, feminine or neuter gender shall include the masculine, the feminine and the neuter. The term “or” is not exclusive. The term “including” (or any form thereof) shall not be limiting or exclusive. All references to statutes and related regulations shall include any amendments of same and any successor statutes and regulations. All references in this Agreement or in the Schedules, Addenda, Annexes and Exhibits to this Agreement to sections, schedules, disclosure schedules, exhibits, and attachments shall refer to the corresponding sections, schedules, disclosure schedules, exhibits, and attachments of or to this Agreement. All references to any instruments or agreements, including references to this Agreement or any of the Ancillary Agreements, shall include any and all modifications or amendments thereto and any and all extensions or renewals thereof.

(e) This Agreement shall be subject to the terms and provisions of the Confirmed Plan. To the extent that there is any conflict between the terms and provisions of this Agreement and the terms and provisions of the Confirmed Plan, the terms and provisions of this Agreement will control unless otherwise expressly stated in the Confirmation Order.

2. The BVTI Term Loans and Closing Shares.

(a) The BVTI Term Notes.

(i) Subject to the terms and conditions set forth herein and in the Ancillary Agreements, at the Closing, the Lenders will receive in satisfaction of the Prepetition

Debt, (A) secured term promissory notes of Biovest in an aggregate principal amount of $24,900,000.00 (the “Term A Notes”) and (B) secured term promissory notes of Biovest in an aggregate principal amount of $4,160,000.00 (the “Term B Notes” and together with the Term A Notes, the “BVTI Term Notes”). The BVTI Term Notes shall be issued to the Lenders in the principal amounts set forth on Schedule 2(a)(i) attached hereto.

(ii) If Biovest at any time fails to perform or observe any of the covenants contained in this Agreement or in any Ancillary Agreement (after any applicable grace period and/or opportunity to cure), the Agent may upon written notice to Biovest, but need not, perform or observe such covenant on behalf and in the name, place and stead of Biovest (or, at the Agent’s option, in the Agent’s name) and may, but need not, take any and all other actions which the Agent may deem necessary to cure or correct such failure (including the payment of Taxes, the satisfaction of Liens, the performance of obligations owed to Account Debtors, lessors or other obligors, the procurement and maintenance of insurance, the execution of assignments, security agreements and financing statements, and the endorsement of instruments). The amount of all monies expended and all out-of-pocket costs and reasonable expenses (including attorneys’ fees and legal expenses) incurred by the Agent in connection with or as a result of the performance or observance of such covenants or the taking of such action by the Agent shall be charged to Biovest and added to the principal amount of the BVTI Term Notes. To facilitate the Agent’s performance or observance of such covenants by Biovest, Biovest hereby irrevocably appoints the Agent, or the Agent’s delegate, acting alone, as Biovest’s attorney in fact (which appointment is coupled with an interest) with the right (but not the duty) from time to time to create, prepare, complete, execute, deliver, endorse or file in the name and on behalf of Biovest any and all instruments, documents, assignments, security agreements, financing statements, applications for insurance and other agreements and writings required to be obtained, executed, delivered or endorsed by Biovest.

(iii) The Agent will account to Biovest monthly with a statement of all advances, charges and payments made pursuant to this Agreement, and such account rendered by the Agent shall be deemed final, binding and conclusive, absent manifest error, unless the Agent is notified by Biovest in writing to the contrary within thirty (30) days of the date such account was rendered specifying the item or items to which objection is made.

(b) Closing Shares. In addition to the issuance of the BVTI Term Notes to the Lenders, in consideration of the cancellation of the Biovest Warrants and the modification of the Biovest Royalty, at the Closing, Biovest shall issue to certain of the Lenders an original stock certificate issued in its name evidencing such Lender’s allocable portion of the Closing Shares, which shares shall be subject to the conditions and restrictions set forth herein and in the Closing Shares Lock-Up Agreement. The total number of Closing Shares to be issued to the Lenders will be Fourteen Million Eight Hundred Thirty-Four Thousand Seven Hundred Eighty-Two (14,834,782), which shall be allocated among the Lenders in accordance with Schedule 2(b) attached hereto. Except for the Closing Shares, the Lenders shall not be entitled to receive any shares of the Biovest Common Stock under this Agreement or the Accentia Security Agreement. The number and allocation of the Closing Shares to the Lenders shall be as set forth on Schedule 2(b) attached hereto. Notwithstanding the provision in the Closing Shares Lock-Up Agreement which provides that the Seller Lenders (as such term is defined in the Closing Shares Lock-Up Agreement) are subject to Rule 144(e) of the Securities Act, Biovest hereby acknowledges that it

does not consider the Lenders, either individually or in the aggregate, to be an Affiliate or Affiliates of Biovest.

3. Repayment of the BVTI Term Loans. The BVTI Term Loans shall be repaid in accordance with the terms of the BVTI Term Notes and as set forth herein. Biovest may prepay the BVTI Term Loans from time to time in accordance with the terms and provisions of the BVTI Term Notes.

4. Reserved.

5. Interest and Payments.

(a) Interest.

(i) Biovest shall pay interest on the BVTI Term Loans at the rates per annum set forth in the BVTI Term Notes.

(ii) In no event shall the aggregate interest payable hereunder or under the BVTI Term Notes exceed the maximum rate permitted under any applicable law or regulation, as in effect from time to time (the “Maximum Legal Rate”), and if any provision of this Agreement or any Ancillary Agreement is in contravention of any such law or regulation, interest payable under this Agreement and each Ancillary Agreement shall be computed on the basis of the Maximum Legal Rate (so that such interest will not exceed the Maximum Legal Rate).

(iii) Biovest shall pay principal, interest and all other amounts payable hereunder, or under any Ancillary Agreement, without any deduction whatsoever, including any deduction for any set-off or counterclaim.

(iv) All Contract Rate payments made by Biovest under the BVTI Term Notes shall be made free and clear of, and without deduction or withholding for or on account of, any future Taxes hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, other than Excluded Taxes. If any Non-Excluded Taxes or Other Taxes are required to be withheld from any amounts payable to any Creditor Party hereunder, the amounts so payable to such Creditor Party shall be increased to the extent necessary to yield to such Creditor Party (after payment of all Non-Excluded Taxes and Other Taxes, including those imposed on payments made pursuant to this paragraph (iv) of this Section 5(a)) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that Biovest shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes that are directly attributable to such Lender’s failure to comply with the requirements of paragraph (vii) of this Section 5(a); and provided, further, however, that if Biovest is required to increase the amounts payable to any Creditor Party by reason of this Section 5(a)(iv), Biovest shall pay such increased amounts within ninety (90) days following the date on which such Non-Excluded Taxes or Other Taxes were withheld.

(v) In addition, subject to 11 U.S.C. §1146(a) and the terms of the Confirmation Order, Biovest shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(vi) Whenever any Non-Excluded Taxes or Other Taxes are payable by Biovest, as promptly as possible thereafter Biovest shall send to the Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by Biovest showing payment thereof (or such other evidence reasonably satisfactory to the Agent). If Biovest fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, Biovest shall indemnify the Creditor Parties for any incremental taxes, interest or penalties that may become payable by any Creditor Party as a result of any such failure.

(vii) Each Lender (or its assignee) that is not a “United States person,” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall, and hereby agrees to, deliver to Biovest and the Agent two completed originals of an appropriate U.S. Internal Revenue Service Form W-8, as applicable, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement. In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify Biovest at any time it determines that it is no longer in a position to provide any previously delivered certificate to Biovest (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(viii) The agreements in this Section 5(a) shall survive the termination of this Agreement and the payment of the BVTI Term Loans and all other amounts payable hereunder or under any other Ancillary Agreement.

(b) Failure to Provide Financial Information. Without affecting the Lenders’ rights and remedies, in the event Biovest fails to deliver the financial information required by Section 11 on or before the dates set forth therein, Biovest shall pay each Lender its pro rata share of an aggregate fee in the amount of $250.00 per week (or portion thereof) for each such failure until the missing financial information is delivered to the Agent. All amounts incurred pursuant to this Section 5(b) shall be due and payable upon receipt by Biovest of an invoice from the Agent for such amounts, which shall be paid monthly, in arrears, on the first Business Day of each calendar month.

6. Security Interest.

(a) Subject only to the Permitted Liens, to secure the prompt payment to the Creditor Parties of the Obligations, Biovest hereby assigns, pledges and grants to the Agent, for the ratable benefit of the Creditor Parties, a continuing security interest in and Lien upon all of the Collateral. All of Biovest’s Books and Records relating to the Collateral shall, until

delivered to or removed by the Agent, be kept by Biovest in trust for the Creditor Parties until the termination of this Agreement and the payment in full of all Obligations. Each confirmatory assignment schedule or other form of assignment hereafter executed by Biovest shall be deemed to include the foregoing grant, whether or not the same appears therein. Notwithstanding the foregoing, the continuing security interests in and Lien upon the Collateral, as provided for herein, shall terminate upon the payment in full of the BVTI Term Notes and all interest, fees, costs, charges, expenses, or other sums payable hereunder and under any Ancillary Agreements (other than the Biovest Contingent Payment Agreement).

(b) Biovest hereby (i) authorizes the Agent to file any financing statements, continuation statements or other amendments thereto that (A) indicate the Collateral (1) as all assets and personal property of Biovest or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC of the applicable jurisdiction, or (2) as being of an equal or lesser scope or with greater detail, and (B) contain any other information required by Part 5 of Article 9 of the UCC for the sufficiency or filing office acceptance of any financing statement, continuation statement or other amendment and (ii) ratifies its authorization for the Agent to have filed any initial financial statements, or amendments thereto if filed prior to the date hereof. Except as otherwise provided in the Confirmed Plan, Biovest acknowledges that it is not authorized to file and, except as expressly set forth in this Agreement, will not give any authorization to anyone other than the Agent (including pursuant to Section 9-509(b) of the UCC) to file, any financing statement or amendment or termination statement with respect to any financing statement without the prior written consent of the Agent and agrees that it will not do so without the prior written consent of the Agent, subject to Biovest’s rights under Section 9-509(d)(2) of the UCC.

(c) Biovest hereby grants to the Agent, for the ratable benefit of the Creditor Parties, an irrevocable, non-exclusive, worldwide license without payment of royalty or other compensation to Biovest, upon the occurrence and during the continuance of an Event of Default, to use or otherwise exploit in any manner as to which authorization of the holder of such Intellectual Property would be required, and to license or sublicense such rights in, to and under any Intellectual Property now or hereafter owned by or licensed to Biovest, and wherever the same may be located, and including in such license access to all media in which any of such Intellectual Property may be recorded or stored and to all software and hardware used for the compilation or printout thereof. Biovest represents, promises and agrees that any such license or sublicense is not and will not be in conflict with the contractual or commercial rights of any third Person and subject, in the case of trademarks and service marks, to sufficient rights to quality control and inspection in favor of Biovest to avoid the right of invalidation of said trademarks and service marks. The foregoing license and sublicense will terminate on the termination of this Agreement and the payment in full of the Obligations; provided, however, that any license, sublicense, or other rights granted by the Agent pursuant to such license during its term in connection with any enforcement of remedies by Agent hereunder shall remain in effect in accordance with its terms.

(d) Any proceeds received by the Agent from the foreclosure, sale, lease or other disposition of any of the Collateral shall be paid over to the Lenders for application in accordance with Section 21.

7. Representations, Warranties and Covenants Concerning the Collateral. Biovest represents, warrants and covenants as of the date hereof as follows:

(a) All of the Collateral (i) is owned by it free and clear of all Liens (including any claim of infringement) except those in the Agent’s favor and Permitted Liens and (ii) is not subject to any agreement prohibiting the granting of a Lien or requiring notice of or consent to the granting of a Lien.

(b) It shall not encumber, mortgage, pledge, assign or grant any security interest in or Lien upon any Collateral to anyone other than the Agent and the other Creditor Parties and except for Permitted Liens.

(c) The Liens granted pursuant to this Agreement, upon the filing of UCC-1 financing statements in respect of Biovest in favor of the Agent in the applicable filing office of the state of organization of Biovest, the recording of the Liens in favor of the Agent in the U.S. Patent and Trademark Office and the U.S. Copyright Office, as applicable, the taking of any actions required under the laws of jurisdictions outside the United States with respect to Intellectual Property included in the Collateral which is created under such laws, and the completion of the other filings and actions listed on Schedule 7(c) attached hereto, have been delivered to the Agent in duly executed form, constitute valid perfected security interests in all of the Collateral in favor of the Agent as security for the payment of the Obligations, enforceable in accordance with the terms hereof against any and all of Biovest’s creditors and purchasers and such security interests are prior to all other Liens in existence on the date hereof except those relating to the Permitted Liens, which, pursuant to the Confirmed Plan, are senior in priority to the Liens granted in favor of the Agent under this Agreement.

(d) No effective security agreement, mortgage, deed of trust, financing statement, equivalent security or Lien instrument or continuation statement covering all or any part of the Collateral is on file or of record in any public office, except those relating to Permitted Liens.

(e) It shall not dispose of any of the Collateral whether by sale, lease or otherwise except for Permitted Liens, the sale of Inventory or license of Intellectual Property in the ordinary course of business, and the disposition or transfer in the ordinary course of business during any fiscal year of obsolete and worn-out Equipment having an aggregate fair market value of not more than $50,000 or to the extent that (i) the proceeds of any such disposition are used to acquire replacement Equipment which is subject to the Agent’s first priority security interest or are used to repay BVTI Term Loans or to pay general corporate expenses, or (ii) following the occurrence of an Event of Default which continues to exist, the proceeds of which are remitted to the Agent to be held as cash collateral for the Obligations.

(f) It shall defend the right, title and interest of the Agent in and to the Collateral against the claims and demands of all Persons whomsoever, and take such actions, including (i) all actions necessary to grant the Agent “control” of any Investment Property, Deposit Accounts, Letter-of-Credit Rights or electronic Chattel Paper owned by Biovest, with any agreements establishing control to be in form and substance satisfactory to the Agent, (ii) the prompt (but in no event later than five (5) Business Days following the Agent’s request therefor)

delivery to the Agent of all original Instruments, Chattel Paper, negotiable Documents and certificated Equity Interests owned by it (in each case, accompanied by stock powers, allonges or other instruments of transfer executed in blank), (iii) notification to third parties of the Agent’s interest in the Collateral at the Agent’s request, and (iv) the institution of litigation against third parties as shall be prudent in order to protect and preserve its and/or the Agent’s respective and several interests in the Collateral.

(g) It shall promptly, and in any event within five (5) Business Days after the same is acquired by it, notify the Agent of any Commercial Tort Claim acquired by it and, unless otherwise consented to by the Agent, it shall enter into a supplement to this Agreement granting to the Agent a Lien in such Commercial Tort Claim.

(h) It shall place notations upon its Books and Records and any of its financial statements to disclose the Agent’s Lien in the Collateral.

(i) Subject to any Permitted Liens, if it retains possession of any Chattel Paper or Instrument with the Agent’s consent, such Chattel Paper and Instruments shall be marked with the following legend: “This writing and obligations evidenced or secured hereby are subject to the security interest of LV Administrative Services, Inc., as agent.” Notwithstanding the foregoing, upon the reasonable request of the Agent, such Chattel Paper and Instruments shall be delivered to the Agent.

(j) It shall perform in a reasonable time all other steps requested by the Agent to create and maintain in the Agent’s favor a valid perfected first Lien in all Collateral subject only to Permitted Liens, which, pursuant to the Confirmed Plan, are senior in priority to the Liens granted in favor of the Agent under this Agreement.

(k) It shall keep and maintain its Equipment in good operating condition, except for ordinary wear and tear, and shall make all necessary repairs and replacements thereof so that the value and operating efficiency shall at all times be maintained and preserved. It shall not permit any such items to become a Fixture to real estate or accessions to other personal property.

(l) It shall maintain and keep all of its Books and Records concerning the Collateral at its executive offices listed in Schedule 12(n).

(m) It shall maintain and keep the tangible Collateral at the addresses listed in Schedule 12(n); provided, that (i) it may change such locations or open a new location if it provides the Agent at least thirty (30) days prior written notice of such changes or new location and (ii) prior to such change or opening of a new location where Collateral having a value of more than $50,000 will be located, it executes and delivers to the Agent such agreements as are deemed reasonably necessary or prudent by the Agent, including landlord agreements, mortgagee agreements and warehouse agreements, each in form and substance satisfactory to the Agent, to adequately protect and maintain the Agent’s security interest in such Collateral.

(n) Schedule 7(n) attached hereto lists all banks and other financial institutions at which it maintains deposits and/or other accounts, and such Schedule 7(n) correctly identifies the name, address and telephone number of each such depository, the name in

which the account is held, and the complete account number. It shall not establish any depository or other bank account with any financial institution (other than the accounts set forth on Schedule 7(n)) without the Agent’s prior written consent.

(o) Its exact legal name (as indicated in the public record of its jurisdiction of organization), jurisdiction of organization, organizational identification number, if any, from the jurisdiction of organization, and the location of its chief executive office or sole place of business or principal residence, as the case may be, are specified on Schedule 7(o) attached hereto. It has furnished to the Agent a certified charter, certificate of incorporation or other organization document and long-form good standing certificate as of a date which is recent to the date hereof. It is organized solely under the law of the jurisdiction so specified and has not filed any certificates of domestication, transfer or continuance in any other jurisdiction. Except as specified on Schedule 7(o), it has not changed its name, jurisdiction of organization, chief executive office or sole place of business or its corporate structure in any way (e.g., by merger, consolidation, change in corporate form or otherwise) within the past five years and has not within the last five years become bound (whether as a result of merger or otherwise) as a grantor under a security agreement entered into by another Person, which has not heretofore been terminated.

(p) It will not, except upon 30 days’ prior written notice to the Agent and delivery to the Agent of (i) all additional financing statements and other documents reasonably requested by the Agent to maintain the validity, perfection and priority of the security interests provided for herein and (ii) if applicable, a written supplement to Schedule 12(n) showing any additional location at which Inventory or Equipment in excess of $50,000 in the aggregate shall be kept: (A) change its jurisdiction of organization or the location of its chief executive office or sole place of business or principal residence from that referred to in Section 7(o); (B) change its name, identity or organizational structure; or (C) permit any of the Inventory or Equipment in excess of $50,000 in the aggregate to be kept at a location other than those listed on Schedule 12(n).

9. Reserved.

10. Inspections and Appraisals. At all times during normal business hours, the Agent, and/or any agent of the Agent, shall have the right to (a) have access to, visit, inspect, review, evaluate and make physical verification and appraisals of Biovest’s properties and the Collateral, (b) inspect, copy (or take originals if necessary) and make extracts from Biovest’s Books and Records, including management letters prepared by the Accountants, and (c) discuss with Biovest’s directors, principal officers, and Accountants, Biovest’s business, assets, liabilities, financial condition, results of operations and business prospects.

Biovest will also deliver to the Agent at such time, if available, copies of any management letters prepared by the Accountants;

(b) As soon as available and in any event within fifty (50) days after the end of each fiscal quarter that is not a fiscal year end of Biovest, an unaudited/internal balance sheet and statements of income, retained earnings and cash flows of Biovest as at the end of and for such quarter and for the year to date period then ended, prepared on a consolidating and consolidated basis to include Biovest and its affiliates, in reasonable detail and stating in comparative form the figures for the corresponding date and periods in the previous year, all prepared in accordance with GAAP, subject to year-end adjustments and accompanied by a certificate of Biovest’s president, chief executive officer or chief financial officer stating that such financial statements have been prepared in accordance with GAAP, subject to year-end audit adjustments;

In furtherance of those efforts, such Lender hereby represents, warrants and covenants that: (i) none of the cash or property that such Lender will use to make the BVTI Term Loans has been or shall be derived from, or related to, any activity that is deemed criminal under United States law; and (ii) no disbursement by such Lender to Biovest, to the extent within such Lender’s control, shall cause such Lender to be in violation of the United States Bank Secrecy Act, the United States International Money Laundering Control Act of 1986 or the United States International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001. Such Lender shall promptly notify Biovest if any of these representations ceases to be true and accurate regarding such Lender. Such Lender agrees to provide Biovest any additional information regarding such Lender that Biovest deems necessary or convenient to ensure compliance with all applicable law concerning money laundering and similar activities. Such Lender understands and agrees that if at any time it is discovered that any of the foregoing representations are incorrect, or if otherwise required by applicable law or regulation related to money laundering or similar activities, such

Lender may undertake appropriate actions to ensure compliance with applicable law or regulation, including but not limited to segregation and/or redemption of such Lender’s investment in Biovest. Such Lender further understands that Biovest may release information about such Lender and, if applicable, any underlying beneficial owners, to proper authorities if Biovest, in its sole discretion, determines that it is in the best interests of Biovest in light of relevant rules and regulations under the laws set forth in subsection (ii) above.

(h) Limitation on Acquisition of Stock. Notwithstanding anything to the contrary contained in this Agreement, any Ancillary Agreement, or any document, instrument or agreement entered into in connection with any other transaction entered into by and between such Lender and Biovest (and/or Affiliates of Biovest), such Lender (and/or Subsidiaries or Affiliates of such Lender) shall not acquire stock in Biovest (including, without limitation, pursuant to a contract to purchase, by exercising an option or warrant, by converting any other security or instrument, by acquiring or exercising any other right to acquire shares of stock or other security convertible into shares of stock in Biovest, or otherwise, and such options, warrants, conversion or other rights shall not be exercisable) to the extent such stock acquisition would cause any interest (including any original issue discount) payable by Biovest to a Non-U.S. Lender not to qualify as portfolio interest, within the meaning of Section 871(h)(2) or Section 881(c)(2) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) by reason of Section 87l(h)(3) or Section 88l(c)(3)(B) of the Code, as applicable, taking into account the constructive ownership rules under Section 871(h)(3)(C) of the Code (the “Stock Acquisition Limitation”).

(i) No Net Short Position. From and after the date of this Agreement, such Lender agrees that it shall not, either individually or collectively, maintain a Net Short Position. “Net Short Position” shall mean that the aggregate number of shares of Biovest Common Stock held in a short position by such Lender exceeds the number of shares of Biovest Common Stock then owned by such Lender.

(j) Ancillary Agreements and Other Closing Documents. The Agent and the Lenders acknowledge and agree that, as a condition to the Closing, the closing under the Accentia Security Agreement shall have occurred and the Agent and the Lenders, as the case may be, shall have executed and delivered each of the Ancillary Agreements and other documents listed in Section 14(c).

17. Confidentiality. Except in connection with the Bankruptcy Cases, each Lender covenants and agrees with Biovest that such Lender will not disclose, and will not include in any public announcement, Biovest’s name, unless expressly agreed to by Biovest or unless and until such disclosure is required by law or applicable regulation, and then only to the extent of such requirement. Notwithstanding the foregoing, (i) such Lender shall be permitted to discuss, distribute or otherwise transfer any non-public information of Biovest in such Lender’s possession now or in the future to (x) its employees, agents, counsel, professional consultants and accountants who, in each such case, have a specific need to know such information, and (y) potential or actual (A) direct or indirect investors in such Lender and (B) assignees or transferees of all or a portion of the Obligations, to the extent that such investor or assignee or transferee enters into a confidentiality agreement for such benefit of Biovest in such form as may be necessary to address Biovest’s Regulation FD requirements; (ii) such Lender (and each

employee, representative, or other agent of such Lender) may disclose to any and all Persons, without limitation of any kind, the tax treatment and any facts that may be relevant to the tax structure of the transactions contemplated by this Agreement and the Ancillary Agreements and the agreements referred to therein; provided, however, that no Lender (and no employee, representative or other agent thereof) shall disclose pursuant to this clause (ii) any other information that is not relevant to understanding the tax treatment or tax structure of such transactions (including the identity of any party or any information that could lead another to determine the identity of any party); and (iii) the Agent or any Affiliate thereof shall be entitled to post on its website a summary of the transactions contemplated by this Agreement, including Biovest’s name.

18. Power of Attorney. Biovest hereby appoints the Agent, or any other Person whom the Agent may designate as Biovest’s attorney, with power to: (a)(i) execute any security related documentation on Biovest’s behalf and to supply any omitted information and correct patent errors in any documents executed by Biovest or on Biovest’s behalf; (ii) file financing statements and other evidence of Liens granted hereunder against Biovest covering the Collateral (and, in connection with the filing of any such financing statements, describe the Collateral as “all assets and all personal property, whether now owned and/or hereafter acquired” (or any substantially similar variation thereof)); (iii) sign Biovest’s name on any invoice or xxxx of lading relating to any Accounts, drafts against Account Debtors, schedules and assignments of Accounts, notices of assignment, financing statements and other evidence of the Agent’s Liens granted hereunder and other public records, verifications of Account and notices to or from Account Debtors; (iv) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Agent may request to evidence the Agent’s security interest in such Intellectual Property and the goodwill and general intangibles of Biovest relating thereto or represented thereby; and (v) do all other things the Agent deems necessary to carry out the terms of Section 6 of this Agreement; and (b) upon the occurrence and during the continuance of an Event of Default (i) endorse Biovest’s name on any checks, notes, acceptances, money orders, drafts or other forms of payment or security that may come into the Agent’s possession; (ii) verify the validity, amount or any other matter relating to any Account by mail, telephone, telegraph or otherwise with Account Debtors; (iii) do all other things necessary to carry out this Agreement, any Ancillary Agreement and all related documents; and (iv) notify the post office authorities to change the address for delivery of Biovest’s mail to an address designated by the Agent, and to receive, open and dispose of all mail addressed to Biovest. Biovest hereby ratifies and approves all acts of the attorney. Neither the Agent nor the attorney will be liable for any acts or omissions or for any error of judgment or mistake of fact or law, except for gross negligence or willful misconduct. This power, being coupled with an interest, is irrevocable so long as the Agent has a security interest and until the Obligations have been fully satisfied.

19. Termination of Lien. The Liens and rights granted to the Agent hereunder and in any Ancillary Agreements, and the financing statements filed in connection herewith or therewith, shall continue in full force and effect until all of the Obligations have been indefeasibly paid or performed in full. The Agent shall not be required to send termination statements or other evidence of the release of the Liens granted hereunder to Biovest, or to file them with any filing office, unless and until this Agreement and the Ancillary Agreements shall

have been terminated in accordance with their terms and all Obligations indefeasibly paid in full in immediately available funds.

20. Events of Default. The occurrence of any of the following shall constitute an “Event of Default”:

(a) failure to make payment of any principal, interest, fees, costs, charges, expenses, or other sums payable from time to time hereunder, under the BVTI Term Notes, under Section 5(b) of this Agreement, if any, or under any of the Ancillary Agreements when required hereunder or thereunder, and, in any such case, such failure shall continue for (i) in the case of a payment of scheduled principal or interest, a period of five (5) Business Days following the date upon which any such payment was due, (ii) in the case of payments due under Section 5(b), if any, that are not paid when due on eight (8) occasions, or (iii) in the case of any other amount payable, a period of five (5) Business Days following the date of Biovest’s written receipt from the Agent of a written notice identifying the amount due and providing reasonable supporting details;

(b) Biovest shall (i) apply for, consent to or suffer to exist the appointment of or the taking of possession by, a receiver, custodian, trustee or liquidator of itself or of all or a substantial part of its property, (ii) make a general assignment for the benefit of creditors, (iii) commence a voluntary case under the federal bankruptcy laws (as now or hereafter in effect), (iv) be adjudicated bankrupt or insolvent, (v) file a petition seeking to take advantage of any other law providing for the relief of debtors, (vi) acquiesce to without challenge within ten (10) days of the filing thereof, or fail to have dismissed within forty-five (45) days, any petition filed against it in any involuntary case under such bankruptcy laws, or (vii) take any action for the purpose of effecting any of the foregoing;

(d) Biovest directly or indirectly sells, assigns, transfers, conveys, or suffers or permits to occur any sale, assignment, transfer or conveyance of all or substantially all of its assets, except as permitted herein.

21. Remedies. Following the occurrence of an Event of Default that is continuing, the Agent shall have the right to demand repayment in full of all Obligations, whether or not otherwise due. Until all Obligations have been fully and indefeasibly satisfied, the Agent shall retain its Lien in all Collateral. The Agent shall have, in addition to all other rights provided herein and in each Ancillary Agreement, the rights and remedies of a secured party under the UCC, and under other applicable law, all other legal and equitable rights to which the Agent may be entitled, including the right to take immediate possession of the Collateral, to require Biovest to assemble the Collateral, at Biovest’s expense, and to make it available to the Agent at a place designated by the Agent which is reasonably convenient to both parties and to enter any of the premises of Biovest or wherever the Collateral shall be located, with or without force or process of law, and to keep and store the same on said premises until sold (and if said premises be the property of Biovest, Biovest agrees not to charge the Agent or any Lender for storage thereof), and the right to apply for the appointment of a receiver for Biovest’s property. Further, the Agent may, at any time or times after the occurrence of an Event of Default that is continuing,

sell and deliver all Collateral held by or for the Agent at public or private sale for cash, upon credit or otherwise, at such prices and upon such terms as the Agent, in its sole discretion, deems advisable or the Agent may otherwise recover upon the Collateral in any commercially reasonable manner. The requirement of reasonable notice shall be met if such notice is mailed postage prepaid to Biovest at Biovest’s address as shown in Section 30, at least ten (10) days before the time of the event of which notice is being given. The Agent may be the purchaser at any sale, if it is public. In connection with the exercise of the foregoing remedies, and not without limitations of any remedies with respect to Intellectual Property Collateral, the Agent may exercise the rights and license granted under Section 6(c) hereof. The proceeds of sale shall be applied first to all costs and expenses of sale, including reasonable attorneys’ fees, and second to the payment (in whatever order the Agent elects) of all Obligations. After the indefeasible payment and satisfaction in full of all of the Obligations, and after the payment by the Agent of any other amount required by any provision of law, including Section 9-608(a)(1) of the UCC (but only after the Agent has received what the Agent considers reasonable proof of a subordinate party’s security interest), the surplus, if any, shall be paid to Biovest or its representatives or to whosoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. Biovest shall remain liable to the Creditor Parties for any deficiency. The parties hereto each hereby agree that the exercise by any party hereto of any right granted to it or the exercise by any party hereto of any remedy available to it (including, without limitation, the issuance of a notice of redemption, a borrowing request and/or a notice of default), in each case, hereunder or under any Ancillary Agreement shall not constitute confidential information and no party shall have any duty to the other party to maintain such information as confidential, except for the portions of such publicly filed documents that are subject to a confidential treatment request made by Biovest to the SEC.

22. Waivers. To the full extent permitted by applicable law, Biovest hereby waives (a) presentment, demand and protest, and notice of presentment, dishonor, intent to accelerate, acceleration, protest, default, nonpayment, maturity, release, compromise, settlement, extension or renewal of any or all of this Agreement and the Ancillary Agreements or any other notes, commercial paper, Accounts, contracts, Documents, Instruments, Chattel Paper and guaranties at any time held by the Agent on which Biovest may in any way be liable, and hereby ratifies and confirms whatever the Agent may do in this regard; (b) all rights to notice and a hearing prior to the Agent’s taking possession or control of, or to the Agent’s replevy, attachment or levy upon, any Collateral or any bond or security that might be required by any court prior to allowing the Agent to exercise any of its remedies; and (c) the benefit of all valuation, appraisal and exemption laws. Biovest acknowledges that it has been advised by counsel of its choices and decisions with respect to this Agreement, the Ancillary Agreements and the transactions evidenced hereby and thereby.

23. Expenses. Biovest shall pay all of the Agent’s out-of-pocket costs and expenses, including reasonable fees and disbursements of outside counsel and appraisers, in connection with the prosecution or defense of any action, contest, dispute, suit or proceeding concerning any matter in any way arising out of, related to or connected with this Agreement or any Ancillary Agreement. Biovest shall also pay all of the Agent’s reasonable fees, charges, out-of-pocket costs and expenses, including fees and disbursements of counsel and appraisers, in connection with (a) the preparation, execution and delivery of any waiver, any amendment thereto or consent proposed or executed in connection with the transactions contemplated by this

Agreement or the Ancillary Agreements, (b) the Agent’s obtaining performance of the Obligations under this Agreement and any Ancillary Agreements, including, but not limited to, the enforcement or defense of the Agent’s security interests, assignments of rights and Liens hereunder as valid perfected security interests, (c) any attempt to inspect, verify, protect, collect, sell, liquidate or otherwise dispose of any Collateral, (d) any appraisals or re-appraisals of any property (real or personal) pledged to the Agent by Biovest as Collateral for, or any other Person as security for, the Obligations hereunder, and (e) any consultations in connection with any of the foregoing. Biovest shall also pay each Creditor Party the customary bank charges for any bank services (including wire transfers) performed or caused to be performed by it at its request or in connection with Biovest’s loan account with such Creditor Party. All such costs and expenses together with all filing, recording and search fees, taxes and interest payable by Biovest to the Creditor Parties shall be payable on demand and shall be secured by the Collateral. If any tax by any Governmental Authority is or may be imposed on or as a result of any transaction between Biovest, on the one hand, and Creditor Party on the other hand, which such Creditor Party is or may be required to withhold or pay, Biovest hereby indemnifies and holds such Creditor Party harmless in respect of such taxes, and Biovest will repay to such Creditor Party the amount of any such taxes which shall be charged to Biovest’s account; and until Biovest shall furnish such Creditor Party with indemnity therefor (or supply such Creditor Party with evidence satisfactory to it that due provision for the payment thereof has been made), such Creditor Party may hold without interest any balance standing to Biovest’s credit and the Agent shall retain its Liens in any and all Collateral.

24. Assignment; Register.

(a) Each Lender may assign any or all of the Obligations to any Person and, subject to acceptance and recordation thereof by the Agent pursuant to Section 24(b) and receipt by the Agent of a copy of the agreement or instrument pursuant to which such assignment is made (each such agreement or instrument, an “Assignment Agreement”), any such assignee shall succeed to all of such Lender’s rights with respect thereto; provided that no Lender shall be permitted to effect any such assignment to a direct competitor of Biovest unless an Event of Default has occurred and is continuing and such Lender has given Biovest no less than fifteen (15) Business Days prior notice of such assignment. Each Lender may from time to time sell or otherwise grant participations in any of the Obligations and the holder of any such participation shall, subject to the terms of any agreement between such Lender and such holder, be entitled to the same benefits as such Lender with respect to any security for the Obligations in which such holder is a participant. Biovest agrees that each such holder may exercise any and all rights of banker’s lien, set-off and counterclaim with respect to its participation in the Obligations as fully as though Biovest were directly indebted to such holder in the amount of such participation. Biovest may not assign any of its rights or obligations hereunder without the prior written consent of the Agent. All of the terms, conditions, promises, covenants, provisions and warranties of this Agreement shall inure to the benefit of each of the undersigned, and shall bind the representatives, successors and permitted assigns of Biovest and the Creditor Parties.

(b) The Agent shall maintain, or cause to be maintained, for this purpose only as agent for each Lender, (i) a copy of each Assignment Agreement delivered to it and (ii) a book entry system, within the meaning of U.S. Treasury Regulation Sections 5f.103-1(c) and 1.871-14(c) (the “Register”), in which it will register the name and address of each Lender and the

name and address of each assignee of each Lender under this Agreement, and the principal amount of, and stated interest on, the BVTI Term Loans owing to each such Lender and assignee pursuant to the terms hereof and each Assignment Agreement. The right, title and interest of the Lenders and their assignees in and to such BVTI Term Loans shall be transferable only upon notation of such transfer in the Register, and no assignment thereof shall be effective until recorded therein. Biovest and each Creditor Party shall treat each Person whose name is recorded in the Register as a Lender pursuant to the terms hereof as a Lender and owner of an interest in the Obligations hereunder for all purposes of this Agreement, notwithstanding notice to the contrary or any notation of ownership or other writing or any BVTI Term Note. The Register shall be available for inspection by Biovest or Lender, at any reasonable time and from time to time, upon reasonable prior notice.

25. No Waiver; Cumulative Remedies. Failure by any Creditor Party to exercise any right, remedy or option under this Agreement, any Ancillary Agreement or any supplement hereto or thereto or any other agreement between or among Biovest and such Creditor Party, will not operate as a waiver; no waiver by any Creditor Party will be effective unless it is in writing and then only to the extent specifically stated. The Creditor Parties’ rights and remedies under this Agreement and the Ancillary Agreements will be cumulative and not exclusive of any other right or remedy which any of the Creditor Parties may have.

26. Application of Payments. Except as otherwise provided in this Agreement or in any Ancillary Agreement, Biovest irrevocably waives the right to direct the application of any and all payments at any time or times hereafter received by the Agent from or on Biovest’s behalf and Biovest hereby irrevocably agrees that the Agent shall have the continuing exclusive right to apply and reapply any and all payments received at any time or times hereafter against the Obligations hereunder in such manner as the Agent may reasonably deem advisable notwithstanding any entry by the Agent upon any of the Agent’s books and records.

27. Indemnity. Biovest hereby indemnifies and holds each Creditor Party, and its respective affiliates, employees, attorneys and agents (each, an “Indemnified Person”), harmless from and against any and all suits, actions, proceedings, claims, damages, losses, liabilities and expenses of any kind or nature whatsoever (including reasonable attorneys’ fees and disbursements and other costs of investigation or defense, including those incurred upon any appeal) which may be instituted or asserted against or incurred by any such Indemnified Person as the result of credit having been extended, suspended or terminated under this Agreement or any of the Ancillary Agreements or with respect to the execution, delivery, enforcement, performance and administration of, or in any other way arising out of or relating to, this Agreement, the Ancillary Agreements or any other documents or transactions contemplated by or referred to herein or therein and any actions or failures to act with respect to any of the foregoing, except to the extent that any such indemnified liability is finally determined by a court of competent jurisdiction to have resulted primarily from such Indemnified Person’s gross negligence, bad faith or willful misconduct. NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE OR LIABLE TO BIOVEST OR TO ANY OTHER PARTY OR TO ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED, SUSPENDED OR

TERMINATED UNDER THIS AGREEMENT OR ANY ANCILLARY AGREEMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.

28. Revival. Biovest further agrees that to the extent it makes a payment or payments to any Creditor Party, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy act, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, the obligation or part thereof intended to be satisfied shall be revived and continued in full force and effect as if said payment had not been made.

29. Borrowing Agency Provisions.

(a) Biovest shall make payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation and liability shall in no way be affected by any extensions, renewals and forbearance granted by the Agent to Biovest, failure of the Agent to give Biovest notice of borrowing or any other notice, any failure of the Agent to pursue to preserve its rights against Biovest, the release by the Agent of any Collateral now or thereafter acquired from Biovest, and such agreement by Biovest to pay upon any notice issued pursuant thereto is unconditional and unaffected by prior recourse by the Agent to Biovest or any Collateral for Biovest’s Obligations or the lack thereof.

(b) Biovest expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which Biovest may now or hereafter have against any other Person directly or contingently liable for the Obligations, or against or with respect to any other’s property (including, without limitation, any property which is Collateral for the Obligations), arising from the existence or performance of this Agreement, until all Obligations have been indefeasibly paid in full and this Agreement has been irrevocably terminated.

30. Notices. Any notice or request hereunder may be given to Biovest or the Agent and the Lenders at the respective addresses set forth below or as may hereafter be specified in a notice designated as a change of address under this Section. Any notice or request hereunder shall be given by registered or certified mail, return receipt requested, hand delivery, overnight mail or facsimile transmission (confirmed by mail).

(a) THIS AGREEMENT AND THE ANCILLARY AGREEMENTS SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

(b) BIOVEST HEREBY CONSENTS AND AGREES THAT THE STATE AND/OR FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN BIOVEST, ON THE ONE HAND, AND ANY CREDITOR PARTY, ON THE OTHER HAND, PERTAINING TO THIS AGREEMENT OR ANY OF THE ANCILLARY AGREEMENTS OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OF THE ANCILLARY AGREEMENTS; PROVIDED, THAT EACH CREDITOR PARTY AND BIOVEST ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF THE COUNTY OF NEW YORK, STATE OF NEW YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE ANY CREDITOR PARTY FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO COLLECT THE OBLIGATIONS, TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF ANY CREDITOR PARTY. BIOVEST EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND BIOVEST HEREBY WAIVES ANY OBJECTION THAT IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS. BIOVEST HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINT AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO BIOVEST AT THE ADDRESS SET FORTH IN SECTION 30 AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE EARLIER OF BIOVEST’S ACTUAL RECEIPT THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE U.S. MAILS, PROPER POSTAGE PREPAID.

(c) THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND/OR OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE BETWEEN ANY CREDITOR PARTY AND/OR BIOVEST ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT, ANY ANCILLARY AGREEMENT OR THE TRANSACTIONS RELATED HERETO OR THERETO.

32. Limitation of Liability. Biovest acknowledges and understands that in order to assure repayment of the Obligations hereunder the Creditor Parties may be required to exercise any and all of the Creditor Parties’ rights and remedies hereunder and agrees that, except as limited by applicable law, neither the Creditor Parties nor any of their respective agents shall be liable for acts taken or omissions made in connection herewith or therewith except to the extent such acts or omissions result from or constitute bad faith, gross negligence or willful misconduct of the Creditor Parties or any of the Creditor Parties’ agents.

33. Entire Understanding; Maximum Interest. This Agreement and the Ancillary Agreements (together with any provisions of the Confirmed Plan relevant to the subject matter hereof) contain the entire understanding among Biovest, the Lenders and the Agent as to the subject matter hereof and thereof and any promises, representations, warranties or guarantees not herein contained shall have no force and effect unless in writing, signed by Biovest and the Agent. Neither this Agreement, the Ancillary Agreements, nor any portion or provisions thereof may be changed, modified, amended, waived, supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged. Nothing contained in this Agreement, any Ancillary Agreement or in any document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the Maximum Legal Rate. In the event that the rate of interest or dividends required to be paid or other charges hereunder exceed the Maximum Legal Rate, any payments in excess of such Maximum Legal Rate shall be credited against amounts owed by Biovest to the Creditor Parties and thus refunded to Biovest.

34. Severability. Wherever possible, each provision of this Agreement or the Ancillary Agreements shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement or the Ancillary Agreements shall be prohibited by or invalid under applicable law such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions thereof.

35. Survival. The representations, warranties, covenants and agreements made herein shall survive any investigation made by any Creditor Party and the Closing of the transactions contemplated hereby; provided, however, the representations and warranties that relate solely to a specific date by their express terms shall only be deemed to have been made as of such date and are hereby represented and warranted to have been true and correct when made. All statements as to factual matters contained in any certificate or other instrument delivered by or on behalf of Biovest pursuant hereto in connection with the transactions contemplated hereby shall be deemed to be representations and warranties by Biovest hereunder solely as of the date of such certificate or instrument. All indemnities set forth herein shall survive the execution, delivery and termination of this Agreement and the Ancillary Agreements and the making and repaying of the Obligations.

36. Captions. All captions are and shall be without substantive meaning or content of any kind whatsoever.

37. Counterparts; Signatures. This Agreement may be executed in one or more counterparts, each of which shall constitute an original and all of which taken together shall constitute one and the same agreement. Any signature delivered by a party via facsimile or electronic transmission shall be deemed to be an original signature hereto.

38. Construction. The parties acknowledge that each party and its counsel have reviewed this Agreement and that the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement or any amendments, schedules or exhibits thereto.

Biovest hereby authorizes each Creditor Party to make appropriate announcements of the financial arrangement entered into by and among Biovest and each Creditor Party, including, without limitation, announcements which are commonly known as tombstones, in such publications and to such selected parties as the Agent shall in its sole and absolute discretion deem appropriate, or as required by applicable law.

40. Joinder. It is understood and agreed that any Person that desires to become a party hereunder, or is required to execute a counterpart of this Agreement after the date hereof pursuant to the requirements of this Agreement or any Ancillary Agreement, shall become a party hereunder by (a) executing a Joinder Agreement in form and substance satisfactory to the Agent, (b) delivering supplements to such exhibits and annexes to this Agreement and the Ancillary Agreements as the Agent shall reasonably request and (c) taking all actions as specified in this Agreement as would have been taken by such party had it been an original party to this Agreement, in each case with all documents required above to be delivered to the Agent and with all documents and actions required above to be taken to the reasonable satisfaction of the Agent.
