10.Events of Default.  The occurrence of an "Event of Default" under any of the other Loan Documents shall constitute an Event of Default under this Agreement.

11.Remedies and Related Rights.  If an Event of Default shall have occurred, and without limiting any other rights and remedies provided herein, under any of the other Loan Documents or otherwise available to Secured Party, Secured Party may exercise one or more of the rights and remedies provided in this Section.

(a)Remedies.  Secured Party may from time to time at its discretion, without limitation and without notice:

(i)exercise in respect of the Collateral all the rights and remedies of a secured party under the Code (whether or not the Code applies to the affected Collateral);

(ii)reduce its claim to judgment or foreclose or otherwise enforce, in whole or in part, the security interest granted hereunder by any available judicial procedure;

(iii)sell or otherwise dispose of, at its office, on the premises of Grantor or elsewhere, the Collateral, as a unit or in parcels, by public or private proceedings, and by way of one or more contracts (it being agreed that the sale or other disposition of any part of the Collateral shall not exhaust Secured Party's power of sale, but sales or other dispositions may be made from time to time until all of the Collateral has been sold or disposed of or until the Indebtedness has been paid and performed in

full), and at any such sale or other disposition it shall not be necessary to exhibit any of the Collateral;

(iv)buy the Collateral, or any portion thereof, at any public sale;

(v)buy the Collateral, or any portion thereof, at any private sale if the Collateral is of a type customarily sold in a recognized market or is of a type which is the subject of widely distributed standard price quotations;

(vi)apply for the appointment of a receiver for the Collateral, and Grantor hereby consents to any such appointment; and

(vii)at its option, retain the Collateral in satisfaction of the Indebtedness whenever the circumstances are such that Secured Party is entitled to do so under the Code or otherwise, to the full extent permitted by the Code, Secured Party shall be permitted to elect whether such retention shall be in full or partial satisfaction of the Indebtedness.

In the event Secured Party shall elect to sell the Collateral, Secured Party may sell the Collateral without giving any warranties as and shall be permitted to specifically disclaim any warranties of title or the like.  Further, if Secured Party sells any of the Collateral on credit, Grantor will be credited only with payments actually made by the purchaser, received by Secured Party and applied to the Indebtedness.  In the event the purchaser fails to pay for the Collateral, Secured Party may resell the Collateral and Grantor shall be credited with the proceeds of the sale.  Grantor agrees that in the event Grantor or any Borrower is entitled to receive any notice under the Code, as it exists in the state governing any such notice, of the sale or other disposition of any Collateral, reasonable notice shall be deemed given when such notice is deposited in a depository receptacle under the care and custody of the United States Postal Service, postage prepaid, at such party's address set forth on the first page hereof, ten (10) days prior to the date of any public sale, or after which a private sale, of any of such Collateral is to be held.  Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given.  Secured Party may adjourn any public or private sale from time to time  by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.  Grantor further acknowledges and agrees that the redemption by Secured Party of any certificate of deposit pledged as Collateral shall be deemed to be a commercially reasonable disposition under Section 9.610 of the Code.

(b)Private Sale of Securities.  Grantor recognizes that Secured Party may be unable to effect a public sale of all or any part of the securities pledged as Collateral because of restrictions in applicable federal and state securities laws and that Secured Party may, therefore, determine to make one or more private sales of any such securities to a restricted group of purchasers who will be obligated to agree, among other things, to acquire such securities for their own account, for investment and not with a view to the distribution or

resale thereof.  Grantor acknowledges that each any such private sale may be at prices and other terms less favorable than what might have been obtained at a public sale and, notwithstanding the foregoing, agrees that each such private sale shall be deemed to have been made in a commercially reasonable manner and that Secured Party shall have no obligation to delay the sale of any such securities for the period of time necessary to permit the issuer to register such securities for public sale under any federal or state securities laws.  Grantor further acknowledges and agrees that any offer to sell such securities which has been made privately in the manner described above to not less than five (5) bona fide offerees shall be deemed to involve a "public sale" for the purposes of Chapter 9 of the Code, notwithstanding that such sale may not constitute a "public offering" under any federal or state securities laws and that Secured Party may, in such event, bid for the purchase of such securities.

(c)Application of Proceeds.  If any Event of Default shall have occurred, Secured Party may at its discretion apply or use any cash held by Secured Party as Collateral, and any cash proceeds received by Secured Party in respect of any sale or other disposition of, collection from, or other realization upon, all or any part of the Collateral as follows in such order and manner as Secured Party may elect:

(i)to the repayment or reimbursement of the reasonable costs and expenses (including, without limitation, reasonable attorneys' fees and expenses) incurred by Secured Party in connection with (A) the administration of the Loan Documents, (B) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, the Collateral, and (C) the exercise or enforcement of any of the rights and remedies of Secured Party hereunder;

(ii)to the payment or other satisfaction of any liens and other encumbrances upon the Collateral;

(iii)to the satisfaction of the Indebtedness;

(iv)by holding such cash and proceeds as Collateral;

(v)to the payment of any other amounts required by applicable law (including without limitation, Section 9.615(a)(3) of the Code or any other applicable statutory provision); and

(vi)by delivery to Grantor or any other party lawfully entitled to receive such cash or proceeds whether by direction of a court of competent jurisdiction or otherwise.

(d)Deficiency.  In the event that the proceeds of any sale of, collection from, or other realization upon, all or any part of the Collateral by Secured Party are insufficient to pay all amounts to which Secured Party is legally entitled, Borrower and any party who guaranteed or is otherwise obligated to pay all or any portion of the Indebtedness shall be liable for the deficiency, together with interest thereon as provided in the Loan Documents, to the full extent permitted by the Code.

(e)Non-Judicial Remedies.  In granting to Secured Party the power to enforce its rights hereunder without prior judicial process or judicial hearing, Grantor expressly waives, renounces and knowingly relinquishes any legal right which might otherwise require Secured Party to enforce its rights by judicial process.  Grantor recognizes and concedes that non‑judicial remedies are consistent with the usage of trade, are responsive to commercial necessity and are the result of a bargain at arm's length.  Nothing herein is intended to prevent Secured Party or Grantor from resorting to judicial process at either party's option.

(f)Other Recourse.  Grantor waives any right to require Secured Party to proceed against any third party, exhaust any Collateral or other security for the Indebtedness, or to have any third party joined with Grantor in any suit arising out of the Indebtedness or any of the Loan Documents, or pursue any other remedy available to Secured Party.  Grantor further waives any and all notice of acceptance of this Agreement and of the creation, modification, rearrangement, renewal or extension of the Indebtedness.  Grantor further waives any defense arising by reason of any disability or other defense of any third party or by reason of the cessation from any cause whatsoever of the liability of any third party.  Until all of the Indebtedness shall have been paid in full, Grantor shall have no right of subrogation and Grantor waives the right to enforce any remedy which Secured Party has or may hereafter have against any third party, and waives any benefit of and any right to participate in any other security whatsoever now or hereafter held by Secured Party.  Grantor authorizes Secured Party, and without notice or demand and without any reservation of rights against Grantor and without affecting Grantor's liability hereunder or on the Indebtedness, to (i) take or hold any other property of any type from any third party as security for the Indebtedness, and exchange, enforce, waive and release any or all of such other property, (ii) apply such other property and direct the order or manner of sale thereof as Secured Party may in its discretion determine, (iii) renew, extend, accelerate, modify, compromise, settle or release any of the Indebtedness or other security for the Indebtedness, (iv) waive, enforce or modify any of the provisions of any of the Loan Documents executed by any third party, and (v) release or substitute any third party. 

(g)Voting Rights.  Upon the occurrence of an Event of Default, Grantor will not exercise any voting rights with respect to securities pledged as Collateral.  Grantor hereby irrevocably appoints Secured Party as Grantor's attorney‑in‑fact (such power of attorney being coupled with an interest) and proxy to exercise any voting rights with respect to Grantor's securities pledged as Collateral upon the occurrence of an Event of Default.

(h)Dividend Rights and Interest Payments.  Upon the occurrence of an Event of Default:

(i)all rights of Grantor to receive and retain the dividends and interest payments which it would otherwise be authorized to receive and retain pursuant to Section 3 shall automatically cease, and all such rights shall thereupon become vested with Secured Party which shall thereafter have the sole right to receive, hold and apply as Collateral such dividends and interest payments; and

(ii)all dividend and interest payments which are received by Grantor contrary to the provisions of clause (i) of this Subsection shall be received in trust for the benefit of Secured Party, shall be segregated from other funds of Grantor, and shall be forthwith paid over to Secured Party in the exact form received (properly endorsed or assigned if requested by Secured Party), to be held by Secured Party as Collateral.

12.Indemnity.  GRANTOR (and BORROWER, if BORROWER is not the GRANTOR) each hereby indemnifies and agrees to hold harmless Secured Party, and its officers, directors, employees, agents and representatives (each an "Indemnified Person") from and against any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature (collectively, the "Claims") which may be imposed on, incurred by, or asserted against, any Indemnified Person arising in connection with the Loan Documents, the Indebtedness or the Collateral (including without limitation, the enforcement of the Loan Documents and the defense of any Indemnified Person's actions and/or inactions in connection  with the Loan Documents); PROVIDED THAT SUCH indemnification SHALL NOT, AS TO ANY Indemnified Person, BE AVAILABLE TO THE EXTENT THAT SUCH liabilities, claims, losses, damages, penalties, costs, expenses or disbursements (a) ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED BY GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH Indemnified Person OR (b) RESULT FROM A CLAIM BROUGHT BY grantor AGAINST AN Indemnified Person FOR BREACH IN BAD FAITH OF SUCH Indemnified Person'S OBLIGATIONS HEREUNDER OR ANY OTHER LOAN DOCUMENT, IF grantor HAS OBTAINED A FINAL AND NONAPPEALABLE JUDGMENT IN ITS FAVOR ON SUCH CLAIM AS DETERMINED BY A COURT OF COMPETENT JURISDICTION.  The indemnification provided for in this Section shall survive the termination of this Agreement and shall extend and continue to

benefit each individual or entity who is or has at any time been an Indemnified Person hereunder.

13.Miscellaneous.

(a)Entire Agreement.  This Agreement contains the entire agreement of Secured Party and Grantor (and Borrower, if Borrower is not the Grantor) with respect to the Collateral.  If the parties hereto are parties to any prior agreement, either written or oral, relating to the Collateral, the terms of this Agreement shall amend and supersede the terms of such  prior  agreements as to transactions on or after the effective date of this Agreement, but all security agreements, financing statements, guaranties, other contracts and notices for the benefit of Secured Party shall continue in full force and effect to secure the Indebtedness unless Secured Party specifically releases its rights thereunder by separate release.

(b)Amendment.  No modification, consent or amendment of any provision of this Agreement or any of the other Loan Documents shall be valid or effective unless the same is in writing and authenticated by the party against whom it is sought to be enforced, except to the extent of amendments specifically permitted by the Code without authentication by the Grantor.

(c)Actions by Secured Party.  The lien, security interest and other security rights of Secured Party hereunder shall not be impaired by (i) any renewal, extension, increase or modification with respect to the Indebtedness, (ii) any surrender, compromise, release, renewal, extension, exchange or substitution which Secured Party may grant with respect to the Collateral, or (iii) any release or indulgence granted to any endorser, guarantor or surety of the Indebtedness.  The taking of additional security by Secured Party shall not release or impair the lien, security interest or other security rights of Secured Party hereunder or affect the obligations of Grantor hereunder.

(d) Waiver by Secured Party.  Secured Party may waive any Event of Default without waiving any other prior or subsequent Event of Default.  Secured Party may remedy any default without waiving the Event of Default remedied.  Neither the failure by Secured Party to exercise, nor the delay by Secured Party in exercising, any right or remedy upon any Event of Default shall be construed as a waiver of such Event of Default or as a waiver of the right to exercise any such right or remedy at a later date.  No single or partial exercise by Secured Party of any right or remedy hereunder shall exhaust the same or shall preclude any other or further exercise thereof, and every such right or remedy hereunder may be exercised at any time.  No waiver of any provision hereof or consent to any departure therefrom shall be effective unless the same shall be in writing and signed by Secured Party and then such waiver or consent shall be effective only in the specific instances, for the purpose for which given and to the extent therein specified.  No notice to or demand in any case shall of itself entitle Grantor (or Borrower, if Borrower is not the Grantor) to any other or further notice or demand in similar or other circumstances.

(e)Costs and Expenses.  Grantor (and Borrower, if Borrower is not the Grantor) will upon demand pay to Secured Party the amount of any and all costs and expenses (including without limitation, reasonable attorneys' fees and expenses), which Secured Party may incur in connection with (i) the transactions which give rise to the Loan Documents, (ii) the preparation of this Agreement and the perfection and preservation of the security interests granted under the Loan Documents, (iii) the administration of the Loan Documents, (iv) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, the Collateral, (v) the exercise or enforcement of any of the rights of Secured Party under the Loan Documents, or (vi) the failure by Grantor (or Borrower, if Borrower is not the Grantor) to perform or observe any of the provisions hereof.

(f)Controlling Law; Venue.  This Agreement is executed and delivered as an incident to a lending transaction negotiated and consummated in Bexar County, Texas, and shall be governed by and construed in accordance with the laws of the State of Texas. Grantor (and Borrower, if Borrower is not the Grantor), for itself and its successors and assigns, hereby irrevocably (a) submits to the nonexclusive jurisdiction of the state and federal courts in Texas, (b) waives, to the fullest extent permitted by law, any objection that it may now or in the future have to the laying of venue of any litigation arising out of or in connection with any Loan Document brought in the District Court of Bexar County, Texas, or in the United States District Court for the Western District of Texas, San Antonio, Division, (c) waives any objection it may now or hereafter have as to the venue of any such action or proceeding brought in such court or that such court is an inconvenient forum, (d) agrees that any legal proceeding against any party to any Loan Document arising out of or in connection with any of the Loan Documents may be brought in one of the foregoing courts, and (e) agrees that service of process upon it may be made by certified or registered mail, return receipt requested, at its address specified herein.  Nothing herein shall affect the right of Lender to serve process in any other manner permitted by law or shall limit the right of Lender to bring any action or proceeding against Grantor (and Borrower, if Borrower is not the Grantor) or with respect to any of Grantor's (or Borrower's, if Borrower is not the Grantor) property in courts in other jurisdictions.  The scope of each of the foregoing waivers is intended to be all encompassing of any and all disputes that may be filed in any court and that relate to the subject matter of this transaction, including, without limitation, contract claims, tort claims, breach of duty claims, and all other common law and statutory claims. Grantor (and Borrower, if Borrower is not the Grantor) acknowledges that these waivers are a material inducement to Lender's agreement to enter into agreements and obligations evidenced by the Loan Documents, that Lender has already relied on these waivers and will continue to rely on each of these waivers in related future dealings.  The waivers in this section are irrevocable, meaning that they may not be modified either orally or in writing, and these waivers apply to any future renewals, extensions, amendments, modifications, or replacements in respect of the applicable Loan Document. In connection with any litigation, this Agreement may be filed as a written consent to a trial by the court.

(g)Severability.  If any provision of this Agreement is held by a court of competent jurisdiction to be illegal, invalid or unenforceable under present or future laws,

such provision shall be fully severable, shall not impair or invalidate the remainder of this Agreement and the effect thereof shall be confined to the provision held to be illegal, invalid or unenforceable.

(h)No Obligation.  Nothing contained herein shall be construed as an obligation on the part of Secured Party to extend or continue to extend credit to Borrower.

(k)Termination.  It is contemplated by the parties hereto that from time to time there may be no outstanding Indebtedness, but notwithstanding such occurrences, this Agreement shall remain valid and shall be in full force and effect as to subsequent outstanding Indebtedness.  Upon (i) the satisfaction in full of the Indebtedness, (ii) the termination or expiration of any commitment of Secured Party to extend credit to Borrower, (iii) written request for the termination hereof delivered by Grantor to Secured Party, and (iv) written release delivered by Secured Party to Grantor, this Agreement and the security interests created hereby shall terminate.  Upon termination of this Agreement and Grantor's written request, Secured Party will, at Grantor's sole cost and expense, return to Grantor such of the Collateral as shall not have been sold or otherwise disposed of or applied pursuant to the terms hereof and execute and deliver to Grantor such documents as Grantor shall reasonably request to evidence such termination.

(l)Cumulative Rights.  All rights and remedies of Secured Party hereunder are cumulative of each other and of every other right or remedy which Secured Party may otherwise have at law or in equity or under any of the other Loan Documents, and the exercise of one or more of such rights or remedies shall not prejudice or impair the concurrent or subsequent exercise of any other rights or remedies.  Further, except as specifically noted as a waiver herein, no provision of this Agreement is intended by the parties to this Agreement to waive any rights, benefits or protection afforded to Secured Party under the Code.

Without limiting Secured Party's rights hereunder, Grantor authorizes Secured Party to file financing statements or amendments thereto under the provisions of the Code as amended from time to time.
