+# Technical description of multimodal extension
+
+## Working principle
+Multimodality extension does most of the stuff which is required for any image input:
+
+- adds the UI
+- saves the images as base64 JPEGs to history
+- provides the hooks to the UI
+- if there are images in the prompt, it:
+ - splits the prompt to text and image parts
+ - adds image start/end markers to text parts, then encodes and embeds the text parts
+ - calls the vision pipeline to embed the images
+ - stitches the embeddings together, and returns them to text generation
+- loads the appropriate vision pipeline, selected either from model name, or by specifying --multimodal-pipeline parameter
+
+Now, for the pipelines, they:
+
+- load the required vision models
+- return some consts, for example the number of tokens taken up by image
+- and most importantly: return the embeddings for LLM, given a list of images
+
+## Prompts/history
+
+To save images in prompt/history, this extension is using a base64 JPEG, wrapped in a HTML tag, like so:
+```
+
+```
+where `{img_str}` is the actual image data. This format makes displaying them in the UI for free. Do note, that this format is required to be exactly the same, the regex used to find the images is: ``.
+
+## LLM input
+To describe the input, let's see it on an example prompt:
+```
+text1text2text3
+```
+where `textN` is N-th text, `` is N-th image, in HTML format specified above.
+
+**The first step is to split the prompt into image/text parts**, so we get:
+```
+['text1', '', 'text2', '', 'text3']
+```
+this is done in `MultimodalEmbedder._split_prompt(...)` function, which returns a list of `PromptPart`s - dataclasses wrapping the separate parts.
+
+This function also appends the image start/end markers to text, which are provided by `AbstractMultimodalPipeline.image_start()` / `AbstractMultimodalPipeline.image_end()` functions. If image start is ``, and end is ``, this function will return:
+```
+['text1', '', 'text2', '', 'text3']
+```
+
+**The returned prompt parts are then turned into token embeddings.**
+
+First, they are modified to token IDs, for the text it is done using standard `modules.text_generation.encode()` function, and for the images the returned token IDs are changed to placeholders. The placeholder is a list of `N` times `placeholder token id`, where `N` is specified using `AbstractMultimodalPipeline.num_image_embeds()`, and placeholder token IDs using `AbstractMultimodalPipeline.placeholder_token_id()`.
+
+Now, based on the token IDs, the prompt might get truncated, especially if `max_new_tokens` are unreasonably high. Unfortunately, it can't be done simply, just by trimming the prompt to be short enough. This way will lead to sometimes splitting the prompt in the middle of an image embedding, which usually breaks the generation. Therefore, in this case, the entire image needs to be removed from input. This is done inside `MultimodalEmbedder._encode_text(...)` function.
+
+**After the tokenization, the tokens need to get embedded**, the text and images are once again treated separately.
+
+The text parts are turned to embeddings, using `AbstractMultimodalPipeline.embed_tokens(...)` function. It uses standard embedding function from the model, but to support many LLMs, the actual function is returned by the pipeline (as it might be different for different LLMs), for LLaMA it is `shared.model.model.embed_tokens(...)`.
+
+The image parts are turned to embeddings, using `AbstractMultimodalPipeline.embed_images(...)` function. This function is specific for a given pipeline, it takes the images as input, forwards them through vision model/projector, and returns the embeddings.
+
+**Now, the returned embeddings are stitched together**, using `torch.cat()`, this is creating the final input to the LLM.
+
+## Pipelines
+
+All of the pipelines should subclass `AbstractMultimodalPipeline` class. The idea is to allow for new pipelines to be added in the same way as user extensions - git clone into `extensions/multimodal/pipelines`.
+
+The pipelines are the description of the vision part, containing vision model/multimodal projector. All of the pipelines should have an unique `name()`, which is then selected by user, in `--multimodal-pipeline` CLI argument. For an example, see `pipelines/llava/llava.py`.
+
+## Pipeline modules
+
+Pipelines are organized into "pipeline modules" - subdirectories in `pipelines` directory. The pipeline modules should contain a file called `pipelines.py`, that should contain the following fields:
+- `available_pipelines: List[str]` - list of pipelines provided by this module, shown as the list of available pipelines to the user
+- `def get_pipeline(name: str, params: dict) -> Optional[AbstractMultimodalPipeline]`: - a function to get a concrete pipeline by `name`, if `name` doesn't match any, should return `None`. `params` is the user settings for multimodal extension
+- `def get_pipeline_from_model_name(model_name: str, params: dict) -> Optional[AbstractMultimodalPipeline]`: - a function to get a pipeline from `model_name`, should be eager to return `None`, unless the determination can be done clearly (for example: minigpt-4 bases on vicuna - it should never return the pipeline, but llava can, as it has its own specific LLM finetune)
+
+**NOTE**: A pipeline module should lazy-import the pipelines only when necessary, and it should keep its imports to minimum
+
+## Pipeline params
+
+The pipelines will get the extension `params` in the constructor. They should honor the following fields:
+- `vision_device` - string, specifying `torch.device` to run the vision model (CLIP/ViT) on
+- `vision_bits` - int, number of fp bits to load the vision model(s) in
+- `projector_device` - string, specifying `torch.device` to run the projector models (Linear layers, QFormer, etc.) on
+- `projector_bits` - int, number of fp bits to load the projector models in
+
+As a helper, `AbstractMultimodalPipeline` has `_get_device(self, setting_name: str, params: dict)` and `_get_dtype(self, setting_name: str, params: dict)` helper functions, which parse string/int and return `torch.device` / `torch.dtype`.

+## Description:
+TL;DR: Lets the bot answer you with a picture!
+
+Stable Diffusion API pictures for TextGen, v.1.2.0
+An extension to [oobabooga's textgen-webui](https://github.com/oobabooga/text-generation-webui) allowing you to receive pics generated by [Automatic1111's SD-WebUI API](https://github.com/AUTOMATIC1111/stable-diffusion-webui)
+
+
+Interface overview
+
+
+
+
+
+Load it in the `--chat` mode with `--extension sd_api_pictures` alongside `send_pictures`
+(it's not really required, but completes the picture, *pun intended*).
+
+
+## History
+
+Consider the version included with [oobabooga's repository](https://github.com/oobabooga/text-generation-webui/tree/main/extensions/sd_api_pictures) to be STABLE, experimental developments and untested features are pushed in [Brawlence/SD_api_pics](https://github.com/Brawlence/SD_api_pics)
+
+Lastest change:
+1.1.0 → 1.1.1 Fixed not having Auto1111's metadata in received images
+
+## Details
+
+The image generation is triggered:
+- manually through the 'Force the picture response' button while in `Manual` or `Immersive/Interactive` modes OR
+- automatically in `Immersive/Interactive` mode if the words `'send|main|message|me'` are followed by `'image|pic|picture|photo|snap|snapshot|selfie|meme'` in the user's prompt
+- always on in `Picturebook/Adventure` mode (if not currently suppressed by 'Suppress the picture response')
+
+## Prerequisites
+
+One needs an available instance of Automatic1111's webui running with an `--api` flag. Ain't tested with a notebook / cloud hosted one but should be possible.
+To run it locally in parallel on the same machine, specify custom `--listen-port` for either Auto1111's or ooba's webUIs.
+
+## Features overview
+- Connection to API check (press enter in the address box)
+- [VRAM management (model shuffling)](https://github.com/Brawlence/SD_api_pics/wiki/VRAM-management-feature)
+- [Three different operation modes](https://github.com/Brawlence/SD_api_pics/wiki/Modes-of-operation) (manual, interactive, always-on)
+- User-defined persistent settings via settings.json
+
+### Connection check
+
+Insert the Automatic1111's WebUI address and press Enter:
+
+Green mark confirms the ability to communicate with Auto1111's API on this address. Red cross means something's not right (the ext won't work).
+
+### Persistents settings
+
+Create or modify the `settings.json` in the `text-generation-webui` root directory to override the defaults
+present in script.py, ex:
+
+```json
+{
+ "sd_api_pictures-manage_VRAM": 1,
+ "sd_api_pictures-save_img": 1,
+ "sd_api_pictures-prompt_prefix": "(Masterpiece:1.1), detailed, intricate, colorful, (solo:1.1)",
+ "sd_api_pictures-sampler_name": "DPM++ 2M Karras"
+}
+```
+
+will automatically set the `Manage VRAM` & `Keep original images` checkboxes and change the texts in `Prompt Prefix` and `Sampler name` on load.
+
+---
+
+## Demonstrations:
+
+Those are examples of the version 1.0.0, but the core functionality is still the same

+
+ ## About
+
+ This extension takes a dataset as input, breaks it into chunks, and adds the result to a local/offline Chroma database.
+
+ The database is then queried during inference time to get the excerpts that are closest to your input. The idea is to create an arbitrarily large pseudo context.
+
+ The core methodology was developed and contributed by kaiokendev, who is working on improvements to the method in this repository: https://github.com/kaiokendev/superbig
+
+ ## Data input
+
+ Start by entering some data in the interface below and then clicking on "Load data".
+
+ Each time you load some new data, the old chunks are discarded.
+
+ ## Chat mode
+
+ #### Instruct
+
+ On each turn, the chunks will be compared to your current input and the most relevant matches will be appended to the input in the following format:
+
+ ```
+ Consider the excerpts below as additional context:
+ ...
+ ```
+
+ The injection doesn't make it into the chat history. It is only used in the current generation.
+
+ #### Regular chat
+
+ The chunks from the external data sources are ignored, and the chroma database is built based on the chat history instead. The most relevant past exchanges relative to the present input are added to the context string. This way, the extension acts as a long term memory.
+
+ ## Notebook/default modes
+
+ Your question must be manually specified between `<|begin-user-input|>` and `<|end-user-input|>` tags, and the injection point must be specified with `<|injection-point|>`.
+
+ The special tokens mentioned above (`<|begin-user-input|>`, `<|end-user-input|>`, and `<|injection-point|>`) are removed in the background before the text generation begins.
+
+ Here is an example in Vicuna 1.1 format:
+
+ ```
+ A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
+
+ USER:
+
+ <|begin-user-input|>
+ What datasets are mentioned in the text below?
+ <|end-user-input|>
+
+ <|injection-point|>
+
+ ASSISTANT:
+ ```
+
+ ⚠️ For best results, make sure to remove the spaces and new line characters after `ASSISTANT:`.
+
+ *This extension is currently experimental and under development.*

+This module implements a benchmark function to evaluate the performance of the embedding pipeline. It expects a configuration JSON file. It must have questions and expected retrieved text.
+For each question, it's essential to have variants of that question. Language is fluid and each person might have their own spin on how they may ask it.
+
+At the end, it will save the results inside a benchmark_{sysdate}.txt file in the main directory.
+
+The benchmark function will return the score as an integer.

+ agencies of the United States of America and/or all other governmental
+ authorities having jurisdiction which are necessary to authorize the
+ Lessee to engage in air transport and to carry on its business as
+
+ -22-
+
+
+
+
+
+ presently conducted and to be conducted with the Aircraft;
+
+ (xiii) Lessee is a "citizen of the United States" as defined
+ in Section 40102(a)(15) of the Federal Aviation Act;
+
+ (xiv) Lessor is entitled to the benefits of Section 1110 of
+ Title 11 of the united States Code with respect to the Aircraft and the

+ in Article 9 of the Uniform Commercial Code) and the place where it keeps
+ its corporate records concerning the Aircraft, all its interest in, to
+ and under any Operative Document and its contracts relating thereto, are
+ located in Honolulu, Hawaii;
+
+ (xvi) Neither Lessee nor any Person who was at such time a
+ Commonly Controlled Person has terminated any Plan or withdrawn from any

+ manner which has or could reasonably be expected to result in any
+ liability under Title IV of ERISA, and no event or condition has occurred
+ or exists as a result of which any such liability could reasonably be
+ expected to be incurred. No Plan maintained or contributed to (or
+ required to be contributed to) by Lessee or any Person who was at such

+
+ (xvii) No part of the Rent or other payments made by Lessee

+
+ Section 6. POSSESSION AND USE; REGISTRATION.
+
+ (a) POSSESSION.
+
+ (i) SUBLEASE, ASSIGNMENT AND TRANSFER. Without the prior
+ written consent of Lessor and each Beneficiary, Lessee will not assign this
+ Lease or sublet, transfer or relinquish possession of the Aircraft, Airframe or
+ any Engine or install any Engine or permit any Engine to be installed on any
+ airframe other than the Airframe or under any circumstances permit the

+ have occurred and be continuing, (B) the action to be taken shall not affect
+ the registration of the Aircraft with the FAA and (C) all necessary approvals
+ of each Governmental Entity having jurisdiction over the Aircraft have been

+ agreements or similar arrangements in each case customary in the airline
+ industry and entered into in the ordinary course of its business with
+ Permitted Sublessees or an air carrier approved by Lessor and each
+ Beneficiary or an FAA licensed engine overhaul agency, provided that
+ Lessee shall give the Beneficiaries 30 days' prior notice thereof
+ (together with a copy of the applicable pooling or interchange
+ agreement); and provided further, however, that: (A) no such agreement or
+ arrangement results in or requires the transfer of title to such Engine;
+ or (B) if Lessor's title to such Engine shall be divested under any such
+ agreement or arrangement, such divestiture shall be deemed to be a
+ Casualty occurrence with respect to such Engine and Lessee shall comply
+ with Section 11(b) hereof in respect thereof;
+
+ (2) deliver possession of the Aircraft, the Airframe or any
+ Engines to the manufacturer thereof for testing or other similar purposes
+ or to any organization for service, repair, maintenance, testing or

+ to the engines (other than Engines), appliances, parts, instruments,
+ appurtenances, accessories, furnishings and other equipment (other than
+ Parts) installed on such airframe (but not to the airframe as an
+ entirety); and (B) the rights of the participants under normal
+ interchange agreements which are customary in the airline industry and do
+ not contemplate, permit, result in or require the transfer of title to
+ theairframe, engines or parts installed thereon;
+
+ (4) install an Engine on an airframe leased to Lessee or
+ owned by Lessee subject to a conditional sale or other security
+ agreement, provided, that: (A) such airframe is free and clear of all
+ Liens except the rights of the parties to the lease or conditional sale
+ or other security agreement covering such airframe and except Liens of
+ the type permitted by clauses (A) and (B) of Section 6(a)(i)(3), and the
+ Lien of any mortgage which either by its terms does not apply to the
+ Engine or which effectively provides that each Engine leased to Lessee
+ hereby shall not become subject to the Lien thereof or to any rights of
+ any party thereunder other than Lessee (with respect to Lessee's rights
+ expressly granted hereunder), notwithstanding the installation of such
+ Engine on any airframe subject to the Lien of such mortgage, unless and
+ until Lessee shall become the owner of such Engine and Lessor shall have
+ no further interest therein, all pursuant to the express terms of this
+ Lease (as evidenced by a written instrument signed by Lessor); and (B)
+ there shall be in effect a written agreement of the lessor or secured
+ party of such airframe (which may be the lease or conditional sale or
+ other security agreement covering such airframe) substantially similar
+ in effect to the agreement of Lessor in Section 6(b) below whereby such
+ lessor or secured party effectively and expressly agrees that neither it
+ nor its successors or assigns will acquire or claim any right, title or
+ interest in any Engine by reason of such Engine being installed on such
+ airframe at any time while such Engine is subject to this Lease, and a
+ copy of such agreement shall be provided to Lessor or any Beneficiary
+ upon its request;
+
+ -25-
+
+
+
+
+
+ (5) sublease the Airframe and the Engines or the engines then
+ installed on the Airframe or any Engine to any Permitted Sublessee;
+ PROVIDED, that such Permitted Sublessee shall not (i) have consented to

+ Section 6(a)(i) (other than a transfer of an Engine which is deemed a Casualty
+ Occurrence) or any other assignment, sublet or transfer of possession consented
+ to in writing by Lessor and the Beneficiary:
+
+ (1) Lessee shall remain primarily liable hereunder for the
+ performance of all of the terms of this Lease to the same extent as if
+ such transfer had not occurred, and no sublease or other relinquishment
+ of possession of the Equipment shall in any way discharge or diminish any
+ of Lessee's obligations to Lessor under this Lease or any of Lessor's
+ rights hereunder and such rights shall continue as if such sublease or
+ transfer had not occurred;
+
+ (2) the term of any sublease (including, without limitation,
+ any option of the sublessee to renew or extend the sublease), interchange
+ or pooling arrangement shall not continue beyond the end of the Term;
+
+ (3) any sublease permitted by this Section 6 shall in
+ addition expressly provide that (v) such sublease is subject and
+ subordinate to all of the terms of this Lease and all rights of Lessor
+ under this Lease, including without limitation Lessor's
+
+ -26-
+
+
+
+
+
+ rights to repossession pursuant to Section 18 and to void such Permitted
+ Sublessee's right to possession upon such repossession, shall apply, (w)
+ such Permitted Sublessee consents to the security assignment by Lessee to
+ Lessor of all of Lessee's right, title and interest in such sublease for
+ purposes of securing Lessee's obligations hereunder and that Permitted
+ Sublessee, upon receipt of a written notice from Lessor that an Event of
+ Default has occurred and is continuing, will make all payments under such
+ sublease to, and, if this Lease has been declared in default pursuant to
+ Section 18 hereof, will return the Equipment only to, Lessor, or as
+ directed by Lessor, for so long as such Event of Default shall continue,
+ (x) the maintenance, operation and insurance provisions of such sublease
+ shall be substantially the same as the provisions of this Lease (whether
+ by requiring such obligations to be performed by such Permitted
+ Sublessee, by Lessee or by both), (y) the Aircraft shall not be operated
+ or used other than as provided in this Lease, and (z) the Lessor may void
+ or terminate such sublease following an Event of Default hereunder but
+ only during the period as such Event of Default shall continue;
+
+ (4) prior to the commencement of any sublease to a Permitted
+ Sublessee, Lessee shall give Lessor and each Beneficiary no less than 10
+ days written notice of the proposed sublease of the Airframe or Engine,
+ as the case may be, which notice shall include the identity of the
+ Permitted Sublessee, the term and rental rate of the sublease and a copy
+ of such sublease; PROVIDED, HOWEVER, that Lessee shall use its reasonable
+ efforts to give such notice earlier than such 10 days if practicable
+ under the circumstances and to advise Lessor and the Beneficiaries at any
+ time at which Lessee commences substantial discussions or negotiations
+ with any Permitted Sublessee with respect to the potential sublease of
+ the Aircraft;
+
+ (5) any sublease shall-expressly prohibit any assignment or
+ further sublease of the Aircraft or any assignment of the rights under
+ such sublease;
+
+ (6) any Wet Lease shall have a term that does not exceed
+ beyond the end of the Term; and
+
+ (7) the Person with which and for which any Wet Lease is

+
+ -27-
+
+
+
+
+

+ operations in, a Permitted Jurisdiction.
+
+ Prior to entering into any sublease of the Airframe and any Engine or engine or
+ any Engine to a Permitted Sublessee, Lessee shall (A) execute and deliver to
+ Lessor and each Beneficiary an assignment of and grant of a security interest
+ in all of Lessee's right, title and interest in such sublease, which assignment
+ shall be in form and substance reasonably satisfactory to Lessor and each
+ Beneficiary, contain the consent to such assignment of such Permitted
+ Sublessee, and be recordable under the Federal Aviation Act and shall be
+ executed, delivered and filed with the FAA for recordation at Lessee's expense
+ on or before commencement of such sublease (provided that such assignment may
+ specify that Lessor may not exercise any of the rights or remedies of the
+ Lessee under such sublease including, without limitation, any right to receive
+ rentals under such sublease or to interfere with the rights of the Lessee to
+ grant waivers or consents under, or to amend the provisions of, any such
+ sublease) unless, and only so long as, an Event of Default hereunder shall have
+ occurred and be continuing, and (B) execute and deliver to Lessor an
+ appropriately completed Uniform Commercial Code financing statement, for filing
+ in Hawaii and each other applicable jurisdiction, evidencing the assignment by
+ Lessee to Lessor of such sublease. In connection with such a sublease of the
+ Aircraft, Lessee shall provide to Lessor and each Beneficiary, at Lessee's or
+ Permitted Sublessee's expense and on or before commencement of such sublease, a
+ legal opinion from counsel to the Permitted Sublessee in form and substance
+ reasonably satisfactory to Lessor and each Beneficiary, as to the due execution
+ and delivery and enforceability of such sublease and assignment of sublease and
+ as to such other matters as Lessor or such Beneficiary may reasonably request.
+ Lessee agrees that any such security assignment granted to the Lessor may be
+ assigned to the Lender, if any, it being understood that such assignment shall
+ be consistent and not contravene the foregoing provisions. Any monies received
+ by Lessor or Lender pursuant to the exercise of its rights under the assignment
+ of any sublease shall be held by Lessor or the Lender as additional security
+ for the performance by Lessee of its obligations under this Lease and, to the
+ extent not applied against amounts due and owing by Lessee hereunder and the
+ exercise of remedies hereunder, shall be returned to Lessee at such time as no
+ Event of Default shall be continuing. All costs and expenses (including
+ reasonable legal fees and expenses) incurred by Lessor, Lender or any
+ Beneficiary in connection with any sublease or the assignment thereof shall be
+ borne by Lessee and reimbursed by Lessee upon demand.
+
+ -28-
+
+
+
+
+
+ (b) RECIPROCAL RECOGNITION OF RIGHTS. In the event Lessee
+ shall have received from the lessor or secured party of any airframe leased to
+ Lessee or owned by Lessee subject to a conditional sale or other security
+ agreement a written agreement complying with clause (B) of Section 6(a)(i)(4)
+ hereof (which agreement may be contained in the lease, conditional sale
+ agreement or security agreement relating to such airframe), and such lease or
+ conditional sale or other security agreement covering such airframe also covers
+ an engine or engines owned by the lessor under such lease or subject to a
+ security interest in favor of the secured party under such conditional sale or
+ other security agreement, Lessor hereby agrees for the benefit of such lessor
+ or secured party that Lessor will not acquire or claim, as against such lessor
+ or secured party, any right, title or interest in any such engine as the result
+ of such engine being installed on the Airframe at any time while such engine is
+ subject to such lease or conditional sale or other security agreement and owned
+ by such lessor or subject to a security interest in favor of such secured
+ party. Lessor also hereby agrees for the benefit of the mortgagee under any
+ mortgage complying with clause (A) of Section 6(a)(i)(4) hereof, relating to
+ installation of an Engine on an airframe leased to Lessee, that Lessor will not
+ acquire or claim, as against such mortgagee, any right, title or interest in
+ any engine subject to the Lien of such mortgage as the result of such engine
+ being installed on the Airframe at any time while such engine is subject to the
+ Lien of such mortgage.
+
+ (c) LAWFUL INSURED OPERATIONS. Lessee will not permit the
+ Aircraft to be maintained, used or operated in violation of any Law of any
+ Governmental Entity, or in violation of any airworthiness certificate, or
+ license or registration issued by any such authority, or contrary to the
+ Manufacturer's or Engine Manufacturer's operating manuals or instructions for
+ the Aircraft or the Engines. In the event that any such Law requires alteration
+ of the Aircraft, then, subject to Section 1 of the Supplemental Agreement,
+ Lessee shall comply therewith at its sole expense and shall maintain the same
+ in proper condition for operation under such Laws. Lessee agrees not to operate
+ the Aircraft, or permit the Aircraft to be operated, (i) unless the Aircraft is
+ covered by insurance as required by the provisions hereof or (ii) contrary to
+ the terms of such insurance. Lessee also agrees not to operate or locate the
+ Aircraft or suffer or permit the Aircraft to be operated or located in any area
+ excluded from coverage by any insurance policy issued pursuant to the
+ requirements of this Lease.
+
+ (d) MAINTENANCE. Lessee, at its own cost and expense, shall,
+ or shall cause a maintenance contract center that is FAA certified for the
+ contracted maintenance of the
+
+ -29-
+
+
+
+
+
+ Aircraft and located in the united States of America or Canada, to:
+
+ (i) service, repair, maintain, overhaul and test, or cause
+ the same to be done to, each Item leased hereunder (A) so as to keep such
+ Item in the same condition as when delivered to Lessee hereunder, fair
+ wear and tear excepted, and in good operating condition, (B) so as to
+ keep the Aircraft in the condition necessary to enable the airworthiness
+ certification of the Aircraft to be maintained in good standing at all
+ times under all applicable FAA rules and regulations, (C) so as to meet
+ the standards observed by Lessee with respect to aircraft of similar type
+ owned or leased by Lessee and operated on similar routes, and in a manner
+ which does not adversely discriminate against the Aircraft compared to
+ similar aircraft operated by Lessee and in a similar manner and with care
+ as that undertaken by the majority of airlines based in the United States
+ of America which operate Boeing 737-200ADV aircraft (it being understood
+ that the obligations hereby imposed upon Lessee by reference to the
+ manner and care undertaken by other airlines is not intended to supersede
+ Lessee's obligations herein with respect to the specific and express
+ terms of this Lease), (D) in strict compliance with Lesseel's
+ FAA-approved Maintenance Program applicable to the Aircraft (including
+ the corrosion prevention control program (CPCP/D6-38528) and aging
+ aircraft program (D6-38505 revision H as applicable per airworthiness
+ directive or per effectivity)), a true and complete copy of which shall
+ be delivered by Lessee to the Lessor which Maintenance Program shall be
+ in substantial conformance with the Manufacturer's recommended
+ maintenance planning document;
+
+ (ii) maintain all records, logs and other materials required
+ by the FAA or the Maintenance Program in respect of the Aircraft with all
+ such records, logs and other material being maintained in the English
+ language;
+
+ (iii) promptly furnish to Lessor or each Beneficiary such
+ information, in English, as may be required to enable Lessor or such
+ Beneficiary to file any reports required to be filed by such Lessor or
+ Beneficiary with any governmental authority concerning the Aircraft;
+
+ -30-
+
+
+
+
+
+ (iv) incorporate into the Aircraft all manufacturer mandatory
+ requirements, orders, "alert" and, to the extent scheduled for a majority
+ of Lessee's other owned or leased aircraft of the same model,
+ "recommended" service bulletins issued by the manufacturers and vendors
+ of the Items (so far as such manufacturers and vendors issue such service
+ bulletins) which become due for compliance during the Term without
+ waiver, exception, deferment or carryover and, in addition, all other
+ service bulletins that Lessee adopts during the Term for a majority of
+ other aircraft of the same model in Lessee's fleet;
+
+ (v) carry out, on each Item, all applicable regulatory
+ regulations, mandatory requirements, orders and airworthiness directives
+ which the FAA may from time to time issue and which become due during or
+ within three months following the expiration of the Term (or within six
+ months following the expiration of the Term if requested by the
+ Beneficiaries at Beneficiaries' cost; however, the Term will not be
+ deemed extended solely as a result of the additional work to terminate
+ the airworthiness directives due after three months after the expiration
+ of the Term and requested by the Beneficiaries) with respect to such
+ Item, without waiver, exception, deferment or carryover beyond the
+ expiration of the Term (except as expressly set forth in the Supplemental
+ Agreement); provided that any inspections and terminating action required
+ by such regulatory regulations, mandatory requirements, orders and
+ airworthiness directives to be performed by a particular date shall be
+ performed by such date;
+
+ (vi) maintain, service, repair and overhaul the Airframe and
+ all Engines to comply with all warranty requirements;
+
+ (vii) except when required by maintenance or expressly
+ permitted by Section 6(a) above, equip the Airframe at all times with two
+ Engines;
+
+ (viii) make available to Lessor upon its reasonable request
+ during the Term, one or more persons with sufficient technical knowledge
+ to assist the Lessor or each Beneficiary in its examination of such
+ materials and documents relating to the maintenance and condition of the
+ Aircraft as the Lessor or each Beneficiary shall from time to time
+ reasonably request; and
+
+ -31-
+
+
+
+
+
+ (ix) without prejudice to Lessee's obligations to repair the
+ Aircraft pursuant to the terms hereof, if any damage occurs to the
+ Aircraft which results in the need for repairs where the costs of such
+ repairs are expected to exceed US$500,000, Lessee shall promptly notify
+ Lessor and each Beneficiary of the details of the repairs required and
+ shall furnish them with a workscope relating thereto, and Lessee shall
+ comply with any reasonable direction of Lessor or each Beneficiary as to
+ the conduct of the repairs to the Aircraft; PROVIDED, HOWEVER, that the
+ Beneficiaries shall review such workscope and inform Lessee of any
+ comments thereon or objections thereto within three Business Days after
+ their receipt thereof; PROVIDED FURTHER, HOWEVER, that Lessee shall be
+ permitted to use a maintenance contractor to perform its obligations
+ pursuant to this Section 6(d) so long as such maintenance contractor is a
+ repair facility approved by the FAA for the contracted repair of the
+ Aircraft which is located in the United States of America or Canada, or
+ other facility acceptable to the Lessor and each Beneficiary.
+
+ (e) REGISTRATION. So long as no Event of Default shall have
+ occurred and be continuing, Lessor shall cause the Aircraft to be duly
+ registered in the name of Lessor with the FAA under the Federal Aviation Act as
+ at the Delivery Date, shall take such actions as are reasonably appropriate (so
+ long as such actions pose no material burden or risk to Lessor or the
+ Beneficiaries) to maintain such registration during the Term, and shall not
+ take any action to interfere with or cancel such registration; provided that,
+ after the Delivery Date, Lessee shall monitor and, to the extent not relating
+ to the U.S. citizenship of the Beneficiaries, maintain such registration;
+ PROVIDED, FURTHER, HOWEVER, that (i) if Lessor shall at any time cease to be a
+ "citizen of the United States" (as defined in the Federal Aviation Act) and if
+ such requirement shall then be necessary to maintain such registration, then
+ the Beneficiaries shall take such action as shall be reasonable and appropriate
+ to maintain such registration (including by appointing a successor trustee
+ under the Trust Agreement or establishing a voting trust covering the
+ Aircraft), (ii) Lessee and Lessor shall cooperate reasonably and in good faith
+ to maintain such registration, and (iii) Lessee shall, at Lessee's expense,
+ be responsible for the filing and registration of the Lease (as supplemented by
+ the Lease Supplement) and for maintaining such registration throughout the
+ Term.
+
+ -32-
+
+
+
+
+
+
+
+ (f) INSIGNIA. Upon delivery of the Aircraft, Lessee agrees to
+ promptly place the Lease Identification in the cockpit in a prominent location
+ and to place the Lease Identification on each Engine. Lessee agrees to make
+ such reasonable changes to the Lease Identification as Lessor may request from
+ time to time.
+

+ herewith during the preceding fiscal year and (b) that no event has
+ occurred which constitutes a Default, or, if such an event has occurred,
+ the nature thereof and action Lessee has taken or is taking to cure the
+ same;
+
+ (iv) from time to time upon request, Lessee will at no cost
+ to Lessor or each Beneficiary provide Lessor or each Beneficiary
+ certified true and complete copies in the English language of the
+ Maintenance Program; provided that Lessor or such Beneficiary shall
+ maintain the confidentiality thereof and shall not disclose the contents
+ thereof to any Person, except as permitted by Section 20(k) and except to
+ the extent necessary
+
+ -33-
+
+
+
+
+
+ to bridge the Aircraft from the Maintenance Program to the maintenance of
+ a subsequent lessee or buyer of the Aircraft or as required by the Law of
+ a jurisdiction in which the Aircraft will be based, operated or
+ registered;
+
+ (v) Lessee will use its reasonable efforts to provide the

+ information and documentation for the preceding calendar year as listed
+ in Exhibit K hereto; PROVIDED, HOWEVER, that if (i) a Default or an Event
+ of Default shall have occurred and be continuing or (ii) Lessee's
+ financial condition changes adversely from its financial condition at the
+ time of the Delivery Date, then, upon notice and a request from Lessor or
+ a Beneficiary, Lessee shall provide such information on a quarterly basis
+ on the 15th day of each January, April, July and October, commencing with
+ the first of such dates to follow the date of such notice.
+
+ (vii) Lessee will use its reasonable efforts to provide the
+ Beneficiaries, within forty-five (45) days prior to the scheduled
+ performance of a block C or D check on the Aircraft, and shall in any
+ event provide Lessor and the Beneficiaries upon request of a Beneficiary
+ with written notice of the time and location of such scheduled block C or
+ D check; and
+
+ (viii) from time to time such other information regarding the
+ business, operations or the financial condition of Lessee as the Lessor

+ respective designees on at least seven (7) days' prior written notice to visit
+ and inspect the Aircraft, its condition, use and operation and the records
+ maintained in connection therewith during normal business hours; PROVIDED,

+ Beneficiaries may conduct such visit and inspection at any time and with or
+ without notice if an Event of Default has occurred and is continuing. Lessor
+ and each Beneficiary shall have no duty to make any such inspection and shall
+ not incur any liability or obligation by reason of not making any such
+ inspection. Lessor's or any Beneficiary's failure to object to any condition
+ or procedure observed or observable in the course of an inspection hereunder
+ shall not be deemed to waive or modify any of the terms of this Lease with
+ respect to such condition or procedure. If such inspection is carried out
+ during a C Check or D Check, then Lessee will open any areas of the Aircraft
+ upon reasonable request of Lessor or a Beneficiary; PROVIDED, HOWEVER, that,
+ with respect to any C Check (other than the last C Check to occur prior to the
+ Return Occasion) the areas to be opened will be limited to those areas that are
+ in the zones of the Aircraft in which Lessee or its maintenance contractor are
+ working; provided further, however, that, with respect to the last C Check to
+ occur prior to the Return Occasion, Lessee will open any areas of the Aircraft
+ upon the reasonable request of Lessor or a Beneficiary.
+
+ Section 8. COVENANTS OF LESSEE.
+
+ Lessee covenants and agrees that:

+ (i) MAINTENANCE OF CORPORATE EXISTENCE. Except as provided in
+ Section 8(iv) below, during the term of this Lease, Lessee will preserve and
+ maintain its corporate existence. Lessee shall also preserve and maintain its
+ rights, privileges, licenses and franchises in all jurisdictions where the
+ failure to do so would have a materially adversely effect upon the Lessee's
+ ability to meet its obligations under this Lease and the other Operative

+ belonging to it, prior to the date on which penalties attached thereto and
+ prior to the date on which any lawful claim, if not paid, would become a Lien
+ upon any of the material property of Lessee.
+
+ (iv) CONSOLIDATION, MERGER, ETC. Without the prior written
+ consent of Lessor and each Beneficiary, Lessee shall not consolidate with,
+ merge with or merge into any other Person or convey, transfer or lease
+ substantially all of its assets as an entirety to any other Person unless, upon
+ and after giving effect to such transaction, (A) the surviving entity has at
+ least the same net worth and gross assets as the Lessee immediately prior to
+ such transaction, such surviving entity is Certified Air Carrier and a "citizen
+ of the United States" as defined in Section 101(16) of the Federal Aviation

+ prior to any change of its principal place of business or chief executive
+ office.
+
+ (vi) NOTICE OF DEFAULT. Promptly after a responsible officer of
+ Lessee obtains knowledge of an event or circumstance that such officer knows
+ constitutes a Default hereunder, Lessee shall notify Lessor in writing of such
+ Default.
+
+ (vii) GOVERNMENTAL CONSENTS. Lessee undertakes to maintain in
+ full force and effect all governmental consents, licenses, authorizations,
+ approvals, declarations, filings and registrations obtained or effected in
+ connection with this Lease (other than those relating to the perfection of a
+ Lender's interest herein and subject to Section 5(b)(i) and Section 6;
+ provided, however, if so requested by a Beneficiary, Lessee shall cooperate
+ with the Beneficiary, at Beneficiary's cost, to perfect the interest of the
+ Lender) and every document or instrument contemplated hereby (including without
+ limitation foreign exchange and transfer permits regarding Dollar amounts due

+ undertakes to obtain or effect any new or additional governmental consents,
+ licenses, authorizations, approvals, declarations, filings or registrations as
+ may become necessary for the performance of any of the terms and conditions of
+ this Lease or any other document or instrument contemplated hereby; PROVIDED,

+
+
+
+
+
+ not be required to effect or maintain any governmental consent, authorization
+ or license that is required by a governmental authority in Delaware, Japan,

+
+ (ix) CERTIFIED AIR CARRIER. Lessee shall at all times remain a
+Certified Air Carrier.
+
+ Section 9. REPLACEMENT OF PARTS; ALTERATIONS, MODIFICATIONS
+ AND ADDITIONS.
+
+ (a) REPLACEMENT OF PARTS. Lessee, at its own cost and
+ expense, will promptly replace all Parts which may from time to time become
+ worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair
+ or permanently rendered unfit for use for any reason whatsoever. In addition,
+ in the ordinary course of maintenance, service, repair, overhaul or testing,
+ Lessee may at its own cost and expense cause to be removed any Parts, whether
+ or not worn out, destroyed, damaged beyond repair or permanently rendered unfit
+ for use, provided that Lessee shall replace at its own cost and expense such
+ Parts as promptly as practicable. All replacement Parts shall be free and clear
+ of all Liens, other than Liens permitted by Section 14 hereof, shall be in at
+ least the same modification status and service bulletin accomplishment status,
+ shall be fully interchangeable as to form, fit and function, shall have been
+ overhauled or repaired and inspected by an agency acceptable to the FAA and
+ shall be in as good an operating condition as, and have a utility at least
+ equal to and a value and remaining warranty reasonably approximating, the Parts
+ replaced (assuming such replaced Parts were in the condition and repair in
+ which they were required to be maintained by the terms hereof) and all
+ historical records since new or last overhaul relating to such Parts (and all
+ historical records since manufacture with respect to Engines, Landing Gears,
+ the APU and all life limited parts installed on any Engine, Landing Gear or
+ APU) shall be maintained by Lessee.
+
+ -37-
+
+
+
+
+
+ All Parts owned by Lessor which are at any time removed from
+ the Aircraft shall remain the property of Lessor and subject to this Lease, no
+ matter where located, until such time as such Parts shall be replaced by Parts
+ which have been incorporated or installed in or attached to the Aircraft and
+ which meet the requirements for replacement Parts specified above. Immediately
+ upon any replacement Part becoming incorporated or installed in or attached to
+ the Aircraft as above provided, (i) title to the removed Part shall thereupon
+ vest in Lessee, free and clear of all rights of Lessor, (ii) title to such
+ replacement Part shall thereupon vest solely in Lessor and (iii) such
+ replacement Part shall become subject to this Lease and be deemed a Part for
+ all purposes hereof to the same extent as the Part which it has replaced.
+
+ (b) ALTERATIONS, MODIFICATIONS AND ADDITIONS. Lessee, at its
+ own expense, shall make such alterations and modifications and additions to the
+ Aircraft as may be required from time to time to meet the applicable standards
+ of the FAA or to comply with any Law, or, if performed by Lessee with respect
+ to a majority of its 737 fleet, any bulletin of the manufacturer of the
+ Aircraft, Engines or Parts. In addition, Lessee, at its own expense, may from
+ time to time make alterations and modifications in and additions to the
+ Aircraft, provided no such alteration, modification or addition diminishes the
+ remaining warranty, value or utility, or impairs the condition or
+ airworthiness, of the Aircraft. Title to all Parts incorporated or installed in
+ or attached or added to the Aircraft as the result of such alteration,
+ modification or addition shall vest immediately in Lessor and become subject to
+ this Lease, without the necessity for any further act of transfer, document or
+ notice. Notwithstanding the foregoing sentence of this Section 9(b), Lessor
+ agrees that so long as no Event of Default shall have occurred and be
+ continuing, Lessee may, at such time during the Term, remove any Part of the
+ Aircraft without replacement, provided that (i) such Part is in addition to,
+ and not in replacement or substitution for, any Part originally incorporated or
+ installed in or attached to the Aircraft at the time of delivery thereof
+ hereunder or any Part in replacement of, or substitution for, any such
+ originally incorporated or installed or attached Part, (ii) such Part is not
+ required to be incorporated or installed in or attached or added to the
+ Aircraft pursuant to the terms of this Section 9 and (iii) such Part can be
+ removed from the Aircraft without diminishing or impairing the value, utility,
+ condition, cosmetic appearance or airworthiness which the Aircraft would have
+ had at such time had such alteration, modification or addition not occurred.
+ Upon the removal by Lessee of any such Part as provided in the preceding
+ sentence, title thereto shall, without further act, vest in Lessee and such
+ Part shall no longer be deemed part
+
+ -38-
+
+
+
+
+
+ of the Aircraft (such a part is herein called a "Removable Part"). Lessee, at
+ its sole expense, shall repair any damage to the Aircraft resulting from any
+ such removal. Any Part not removed by Lessee as above provided prior to the
+ return of the Aircraft to Lessor hereunder whether pursuant to Section 16,
+ Section 18 or otherwise shall remain the property of Lessor. If any Removable
+ Part is (i) owned by any third party and leased to Lessee, (ii) sold to Lessee
+ subject to a conditional sales contract or other security interest or (iii)
+ leased to Lessee pursuant to a lease which is subject to a security interest in
+ favor of any third party, then Lessor will not acquire or claim, as against
+ such lessor, conditional vendor or secured party, any right, title or interest
+ in any such Removable Part as the result of such Removable Part being installed
+ in the Aircraft; provided, however, (a) that Lessor's inability to so acquire
+ or claim is subject to the express condition that such lessor, conditional
+ vendor or secured party shall not acquire or claim, as against Lessor, any
+ right, title or interest in the Aircraft, or any Part other than its interest
+ in such Removable Part by reason of such Removable Part being installed
+ thereon, and (b) that all of Lessee's right, title and interest in and to any
+ Removable Part not removed by Lessee within sixty (60) days after an Event of
+ Default shall, at such time, automatically become the property of Lessor and be
+ subject to this Lease.
+
+ In addition, with the prior written consent of the
+ Beneficiaries, Lessee may, at its own expense, substitute or replace any Part
+ that is originally installed on the Aircraft on the Delivery Date with another
+ Part provided that (i) no such substitution or replacement diminishes the
+ remaining warranty, value or utility, or impairs the condition or
+ airworthiness, of the Aircraft, (ii) title to all Parts incorporated or
+ installed in or attached or added to the Aircraft as the result of such
+ substitution or replacement shall vest immediately in Lessor free and clear of
+ Liens, other than those permitted by Section 14, and become subject to this
+ Lease, without the necessity for any further act of transfer, document or
+ notice, (iii) such substituted or replacement Parts can be removed from the
+ Aircraft without diminishing or impairing the value, utility, condition,
+ cosmetic appearance or airworthiness which the Aircraft would have had at such
+ time had such substitution or replacement not occurred, (iv) Lessee, at its
+ sole expense, shall repair any damage to the Aircraft resulting from any such
+ removal, and (v) nothing herein shall diminish or alter any of Lessee's
+ obligations under Section 16 or Exhibit E hereof to return the Aircraft on the
+ Return Occasion with all Parts (or substitution or replacement Parts of the
+ same make and model) that were originally installed on the Aircraft in the
+ condition required thereby (and including within this clause (v)
+
+ -39-
+
+
+
+
+
+ Lessee's obligation by the Return Occasion to re-install any Part for which a
+ substitution or replacement Part was installed on the Aircraft pursuant to this
+ paragraph).
+
+ In no event shall Lessor bear any liability or cost for any
+ alteration, modification or addition to, or for any grounding or suspension of
+ certification of, the Aircraft, or for any loss of revenue arising therefrom.
+ Lessee shall make no material alterations, modifications or additions to the
+ Aircraft (such as removal of seats, galleys, lavatories, major avionics
+ equipment or the like) that would affect the marketability of the Aircraft
+ without Lessor's and each Beneficiary's prior written consent. if Lessor and
+ each Beneficiary grant such consent, title to such removed Parts shall remain
+ with Lessor and Lessor and the Beneficiaries may request Lessee to reinstall
+ such Parts prior to termination of this Lease. If Lessor or Beneficiaries
+ request Lessee to reinstall such Parts, title to the Parts removed shall vest
+ in Lessee. All costs associated with such removal and reinstallation shall be
+ borne by Lessee.
+
+ Section 10. GENERAL TAX INDEMNITY.
+
+ (a) CERTAIN UNITED STATES TAXES. Lessee shall indemnify and
+ hold each Indemnitee harmless from and against all United States Withholding
+ Taxes (as defined herein) and United States Transportation Taxes (as defined
+ herein) which are imposed on such Indemnitee after the date hereof as a result
+ of a Tax Law Change (as defined herein). All payments required to be made by
+ Lessee under this Lease or any other Operative Document to any Indemnitee shall
+ be made free and clear of, and without deduction for or on account of, any such
+ United States Withholding Taxes or United States Transportation Taxes. If any
+ such United States Withholding Taxes or United States Transportation Taxes are
+ required to be withheld or deducted from any such payments, Lessee shall (i)
+ within the period for payment permitted by applicable law pay to the
+ appropriate Governmental Entity or taxing authority the full amount of such
+ United States Withholding Taxes or United States Transportation Taxes (and any
+ such additional United States Withholding Taxes or United States Transportation
+ Taxes in respect of the payment required under clause (ii) hereof) and make
+ such reports and filings in connection therewith in the manner required by
+ applicable Law, and (ii) pay to the relevant Indemnitee an additional amount
+ which (after deduction of all Taxes of any nature incurred by reason of the
+ payment or receipt of such additional amount) will be sufficient to yield to
+ the relevant Indemnitee the full amount which would have been received by it
+ had no deduction or withholding been made. Lessor will, and will cause each
+ Indemnitee to, provide Lessee with such forms or certificates as may from time
+ to
+
+ -40-
+
+
+
+
+
+ time be requested by Lessee (and required by applicable law) in order to
+ establish an exemption from (or reduced rate of) any such United States
+ Withholding Taxes or United States Transportation Taxes. As used herein, (x)
+ the term "TAX LAW CHANGE" means any change after the date hereof in the Code or
+ any treaty or other international agreement to which the United States is a
+ party, any proposed, final or temporary regulations thereunder, or the judicial
+ or official administrative interpretation of any of the foregoing; (y) the term
+ "UNITED STATES TRANSPORTATION TAXES" means the Taxes described in Section 887
+ of the Code or any successor to such Section; and (z) the term "UNITED STATES
+ WITHHOLDING TAXES" means Taxes imposed by the United States and which are
+ collected by withholding at source, or deduction from, any payments by Lessee
+ hereunder. Notwithstanding the foregoing, Lessee shall have no responsibility
+ for, and shall be entitled to withhold and deduct from payments hereunder or
+ any other Operative Documents, any such United States Withholding Taxes or
+ United States Transportation Taxes:
+
+ (A) which are imposed by reason of a voluntary transfer or
+ other disposition by the relevant Indemnitee of the Aircraft or this
+ Lease or any interest in either thereof (but not including any transfer
+ or disposition which occurs pursuant to the exercise of remedies arising
+ out of an Event of Default) or which exceed the amount of such United
+ States Withholding Taxes or United States Transportation Taxes which
+ would have been imposed had there not been such a transfer or
+ disposition;
+
+ (B) which are imposed on an Indemnitee by reason of a failure
+ by such Indemnitee to comply with its obligations set forth in the second
+ preceding sentence of this Section 10(a) or as a direct result of the
+ breach by such Indemnitee of this Lease or the gross negligence or
+ willful misconduct of such Indemnitee;
+
+ (C) which are imposed solely as a direct result of events or
+ circumstances occurring or arising after return of the Aircraft to Lessor
+ in accordance with this Lease and the performance by Lessee of all of its
+ obligations hereunder; or
+
+ (D) which the relevant Indemnitee is entitled to utilize as a
+ credit against or in reduction of its liability, if any, for Taxes
+ imposed by the United States for which Lessee is not responsible under
+ Section 10(b) hereof.
+
+ (b) GENERAL TAX INDEMNITY. In addition, and whether or not
+ any of the transactions contemplated by any of the Operative Documents
+ are consummated, except as set
+
+ -41-
+
+
+
+
+
+ forth in Section 10(c), Lessee agrees for the express benefit of each
+ Indemnitee to pay promptly when due, and to indemnify and hold harmless such
+ Indemnitee from, all Taxes (whether imposed upon such Indemnitee, the Aircraft,
+ the Airframe, the Engines, this Lease or any other Operative Document or
+ otherwise), by any Governmental Entity or taxing authority in the United States
+ of America or any other country or any taxing authority or political
+ subdivision thereof or therein or by any international taxing authority, upon
+ or with respect to, based upon or measured by any of the following:
+
+ (i) (x) the Aircraft, the Airframe, any Engine or any Part thereof, or
+ interest therein, this Lease or any of the other Operative Documents, (y) the
+ importation, exportation, condition, manufacture, purchase (under the
+ Operative Documents or otherwise), ownership, delivery, redelivery,
+ nondelivery, acceptance, rejection, assignment, possession, repossession,
+ return, use, performance, operation, control, settlement of any insurance or
+ other claim, sale, mortgaging, pledging, financing, leasing, subleasing, liens,
+ rental, retirement, abandonment, registration, preparation, installation,
+ modification, repair, testing, maintenance, replacement, transportation,
+ storage, location, condition, registration, reregistration, deregistration,
+ sale, transfer of title or other application or disposition of the Aircraft,
+ the Airframe, any Engine or any Part thereof or (z) the rentals, receipts or
+ earnings arising therefrom (including without limitation the Rent) and any
+ other amounts paid or payable with respect thereto or under any Operative
+ Document, or
+
+ (ii) the Lease or the other Operative Documents, or
+
+ (iii) otherwise with respect to or in connection with the transactions
+ contemplated by the Lease and the other Operative Documents.
+
+ (c) EXCEPTIONS TO INDEMNITY. The indemnity provided for in
+ Section 10(b) does not extend to any of the following Taxes:
+
+ (i) Taxes imposed on any Indemnitee in any jurisdiction in which such
+ Indemnitee is subject to such Taxes solely as a result of transactions or
+ activities unrelated to the transactions or activities contemplated by the
+ Operative Documents;
+
+ -42-
+
+
+
+
+
+ (ii) Taxes imposed on an Indemnitee as a result of a voluntary
+ transfer or other disposition of the Aircraft or this Lease or any interest in
+ either thereof by the Lessor or such Indemnitee unless such transfer or
+ disposition occurs pursuant to the exercise of remedies arising out of an Event
+ of Default (provided that Lessor and such Indemnitee shall in such event
+ consider in good faith any reasonable request by Lessee concerning an
+ appropriate jurisdiction in which such sale, transfer or disposition shall be
+ made);
+
+ (iii) Taxes attributable solely to events or circumstances occurring
+ or arising after return of the Aircraft to Lessor in accordance with this Lease
+ and the performance by Lessee of all of its obligations hereunder;
+
+ (iv) Taxes on an Indemnitee resulting solely as a direct result of the
+ breach of this Lease, gross negligence or willful misconduct of such
+ Indemnitee;
+
+ (v) Taxes which (A) are United States federal income Taxes (other than
+ United States Withholding Taxes or United States Transportation Taxes) or any
+ value added, consumption or similar Taxes which are imposed in lieu of or in
+ replacement of United States federal income Taxes to which the relevant
+ Indemnitee was theretofore subject or (B) are Taxes on, based on, or measured
+ by the net income of an Indemnitee and are imposed by any Governmental Entity
+ (other than the United States) or taxing authority thereof (or any Taxes which
+ are expressly imposed by such Governmental Entity or taxing authority in lieu
+ of Taxes on, based on, or measured by net income) except to the extent that
+ such Taxes are imposed by reason of the use or operation of the Aircraft, the
+ presence of Lessee or the making of payments by Lessee from, such jurisdiction;
+ PROVIDED, HOWEVER, that this exclusion shall not apply to Taxes which are, or
+ are in the nature of, sales, use, excise and similar Taxes;
+
+ (vi) Taxes (other than Taxes described in Section 10(c)(v)) which are
+ imposed in any taxing jurisdiction except to the extent that (A) such Taxes are
+ imposed solely by reason of the use or operation of the Aircraft, the presence
+ of Lessee or the making of payments by Lessee from, such jurisdiction ("Use
+ Jurisdiction Taxes") and (B) such Use Jurisdiction Taxes exceed in the
+ aggregate the amount of Taxes which would have been payable in such
+ jurisdiction in the absence therein of the use or operation of the Aircraft,
+ the presence of Lessee or the making of payments by Lessee from, such
+ jurisdiction;
+
+ -43-
+
+
+
+
+
+ (vii) Taxes arising out of, with respect to, based on or measured by
+ the granting by any Indemnitee of a security interest in the Aircraft or any
+ portion thereof or the value or principal amount of any debt created by any
+ Indemnitee; or
+
+ (viii) Taxes for which the relevant Indemnitee has expressly assumed
+ responsibility under this Lease or any other Operative Document.
+
+ (d) AFTER TAX BASIS. The amount which Lessee is required to
+ pay or indemnify against with respect to any amounts required to be paid or
+ indemnified against under this Section 10 or Section 13 shall include an
+ additional amount necessary to hold the recipient of the payment or indemnity
+ harmless on an after-tax basis from all Taxes (whether or not such taxes are
+ excluded under Section 10(a) or 10(c)), required to be paid by such recipient
+ with respect to such payment or indemnity, so as to restore the recipient on an
+ after-tax basis to the same position such recipient would have been in had such
+ amounts not been incurred or payable, after giving credit to Lessee for any
+ savings by such recipient in respect to any such Taxes by reason of deductions,
+ credits, allocations, or allowances in respect of the payment or accrual of the
+ amount indemnified against, including, without limitation, amounts described in
+ Section 10(a), Section 10(b) and/or this Section 10(d). All determinations as
+ to the amount and timing of realization of such tax savings shall be made by
+ the relevant Indemnitee in its sole good faith discretion, it being understood
+ that (i) Lessee shall have no right to examine or inspect any tax returns or
+ reports of such Indemnitee or any documents or records relating thereto, and
+ that (ii) a failure by the relevant Indemnitee to comply with its obligations
+ under this Section 10(d) shall not excuse Lessee from the performance of its
+ obligations under this Section 10 or Section 13.
+
+ (e) TIMING OF PAYMENT. Any amount due and payable to the
+ relevant Indemnitee pursuant to this Section 10 will be paid within 10 days
+ after receipt of a written demand therefor from such Indemnitee accompanied by
+ a written statement describing in reasonable detail the basis for such
+ indemnity and the computation of the amount so payable; PROVIDED, HOWEVER, that
+ such amount need not be paid by Lessee prior to the later of (i) five days
+ prior to the date the applicable Tax is payable to the appropriate Governmental
+ Entity or taxing authority or (ii) in the case of amounts which are being
+ contested by Lessee in good faith or by Lessor pursuant to Section 10(f), the
+ date such contest is finally resolved. If requested in writing by Lessee, and
+ at Lessee's sole cost and expense, any calculations by an Indemnitee of any
+ amount due and payable
+
+ -44-
+
+
+
+
+
+ hereunder shall be subject to review and verification by a firm of independent
+ certified public accounts of internationally recognized stature selected by
+ such Indemnitee and reasonably acceptable to Lessee (such approval not to be
+ unreasonably withheld or delayed). Such Indemnitee shall make available to such
+ accounting firm such information as shall be necessary for purposes of such
+ review and verification (but such information shall be held by such accounting
+ firm in strictest confidence and shall not in any event be disclosed or made
+ available to Lessee). If the result of such review is that Lessee was liable
+ for a smaller amount, the excess payment shall be returned by such Indemnitee
+ forthwith.
+
+ (f) TAX CONTESTS. (i) If written claim is made against an
+ Indemnitee for, or any Indemnitee acquires actual knowledge of a claim relating
+ to, Taxes with respect to which Lessee is or may be liable for a payment or
+ indemnity hereunder, such Indemnitee will, and Lessor shall cause such
+ Indemnitee to, promptly give Lessee notice in writing of such claim or Tax;
+ PROVIDED, HOWEVER, that such Indemnitee's failure to give notice will not
+ relieve Lessee of its obligations hereunder, except as to Taxes and expenses
+ which would have been avoidable in the absence of, and penalties resulting
+ from, such Indemnitee's failure to give such notice. So long as (i) a contest
+ of such Taxes does not involve any danger of the sale, forfeiture or loss of
+ the Aircraft or any interest therein, (ii) Lessee has provided Lessor with an
+ opinion of independent tax counsel acceptable to such Indemnitee that a
+ meritorious basis exists for contesting such claim and (iii) Lessee has made
+ adequate reserves for such Taxes or, if required by the relevant Indemnitee, an
+ adequate bond has been posted by Lessee, then the Indemnitee at Lessee's
+ written request will in good faith, with due diligence and at Lessee's sole
+ cost and expense, contest (or, upon Lessee's written request, permit Lessee to
+ contest in the name of the Indemnitee) the validity, applicability or amount of
+ such Taxes. If such contest is to be initiated by the payment of, and the
+ claiming of a refund for, any Taxes, Lessee shall advance to the relevant
+ Indemnitee sufficient funds (on an interest-free basis) to make such payments
+ and shall have agreed to indemnify such Indemnitee for any tax consequences
+ resulting from such advance of funds. Although the relevant Indemnitee may
+ consult in good faith with Lessee concerning the conduct of any contest, such
+ Indemnitee shall control the conduct of all proceedings relating to any such
+ contest which is brought by or on behalf of such Indemnitee. Any contest
+ initiated hereunder may be settled or discontinued by the relevant Indemnitee
+ at any time provided that such Indemnitee shall have waived any right to
+ indemnification for the Taxes being contested. Notwithstanding the foregoing,
+ if (x) a claim relates solely to Taxes for which
+
+ -45-
+
+
+
+
+
+ the Lessee has acknowledged in writing that it is liable under this Section 10,
+ (y) such claim can be severed and contested separately from all other claims
+ asserted against the relevant Indemnitee by the same taxing authority, and (z)
+ Lessee has made adequate reserves for the Taxes claimed or, if requested by
+ such Indemnitee, has posted an adequate bond for the payment of such Taxes,
+ then Lessee may, at its sole cost and expense, assume control of the contest of
+ such claim, provided that Lessee shall keep such Indemnitee fully informed as
+ to the conduct of all proceedings relating to such contest.
+
+ (g) REFUNDS. Upon receipt by the relevant Indemnitee of a
+ refund of all or any part of any Taxes (including without limitation any
+ deductions or withholdings referred to in Section 10(a)) which Lessee has paid,
+ such Indemnitee will, and Lessor will cause such Indemnitee to, pay to Lessee
+ the net amount of such taxes refunded, together with any interest (and, to the
+ extent previously paid by Lessee, any attorneys' fees or other costs awarded as
+ a result of a contest pursuant to Section 10(f)) received by such Indemnitee
+ with respect thereto; PROVIDED, HOWEVER, that no amount shall be payable to the
+ Lessee under this Section 10(g) if a Default or an Event of Default shall have
+ occurred and be continuing or prior to the time that Lessee shall have paid to
+ the relevant Indemnitee all amounts then due and owing to such Indemnitee under
+ this Section 10.
+
+ (h) COOPERATION IN FILING TAX RETURNS. In case any report or
+ return is required with respect to any Taxes which are subject to
+ indemnification by Lessee under this Section 10, Lessee will either make such
+ report or return in such manner as will show the respective interests of Lessor
+ and/or each relevant Indemnitee in the Aircraft, and send a copy of such report
+ or return to Lessor and such Indemnitee or will notify the Lessor or such
+ Indemnitee of such requirement, prepare such report or return in such manner as
+ shall be reasonably satisfactory to the Lessor or such Indemnitee, and present
+ such report or return to Lessor or such Indemnitee for execution and proper
+ filing. If actual notice is given by any taxing authority to an Indemnitee that
+ a report or return is required to be filed with respect to any such Taxes
+ referred to in this Section 10, the Indemnitee shall, and Lessor shall cause
+ the Indemnitee to, promptly notify Lessee of such required report or return.
+ Each Indemnitee agrees, and Lessor shall cause each Indemnitee, to respond to
+ any reasonable request of Lessee for information within the control of such
+ Indemnitee with respect to the filing of any such report or return, but Lessee
+ agrees to pay any reasonable costs, fees or other charges of independent
+ counsel or independent accountants incurred in connection with such response or
+ request. Lessee will cooperate with each Indemnitee in providing
+
+ -46-
+
+
+
+
+
+ information which may reasonably be required to fulfill such Indemnitee's tax
+ filing requirements and any audit information request arising from such filing.
+ Each Indemnitee shall, and Lessor shall cause each Indemnitee to, cooperate
+ with Lessee in providing information which may reasonably be required to
+ fulfill Lessee's tax filing requirements and any audit information request
+ arising from such filing.
+
+ (i) TAX SAVINGS. If as a result of the payment or accrual of
+ Taxes paid or indemnified by the Lessee an Indemnitee shall realize and
+ recognize any savings with respect to Taxes, such Indemnitee shall promptly
+ notify the Lessee that it has realized and recognized such savings and shall
+ pay to the Lessee within thirty (30) days of the realization of such savings an
+ amount equal to (i) the net reduction in Taxes realized and recognized by such
+ Indemnitee and (ii) the amount of any further net reduction in taxes realized
+ and recognized under such tax laws as a result of payments pursuant to this
+ sentence; PROVIDED, HOWEVER, that no amount shall be payable to the Lessee
+ under this Section 10(i) if a Default or an Event of Default shall have
+ occurred and be continuing or prior to the time that Lessee shall have paid to
+ the relevant Indemnitee all amounts then due and owing to such Indemnitee under
+ this Section 10 and that a subsequent disallowance of any such tax savings
+ shall be subject to indemnity hereunder without regard to any exclusions set
+ forth in this Section 10. All determinations as to the amount and timing of
+ realization of such tax savings shall be made by the relevant Indemnitee in its
+ sole good faith discretion, it being understood that (i) Lessee shall have no
+ right to examine or inspect any tax returns or reports of such Indemnitee
+ or any documents or records relating thereto, and that (ii) a failure by the
+ relevant Indemnitee to comply with its obligations under this Section 10(i)
+ shall not excuse Lessee from the performance of its obligations under this
+ Section 10.
+
+ (j) REVERSE INDEMNITY. If Lessee shall be required to pay any
+ amount attributable to Taxes of any Indemnitee for which Lessee is not
+ responsible under this Section 10, such Indemnitee shall reimburse Lessee for
+ the amount of any such excess payment within 5 days after demand therefor.
+
+ Section 11. CASUALTY OCCURRENCES.
+
+ (a) CASUALTY OCCURRENCE WITH RESPECT TO THE AIRFRAME.
+ Promptly (and in any event within seven (7) days) after a Casualty Occurrence
+ with respect to the Airframe and any Engine then installed thereon, Lessee
+ shall give Lessor and each Beneficiary written notice of such occurrence. On
+ the thirtieth (30th) day (or earlier if the insurance or
+
+ -47-
+
+
+
+
+
+ other proceeds have been paid earlier) after the date of the Casualty
+ Occurrence, Lessee shall pay to Lessor in immediately available funds the
+ sum of (A) the Casualty Value of the Aircraft less an amount equal to the
+ daily equivalent of Basic Rent (computed on the basis of a 365-day year)
+ for each day during the period commencing the day after the payment of
+ Casualty Value and extending to the day before the Basic Rent Payment Date
+ immediately succeeding the date of payment of such Casualty Value and (B)
+ all other Rent, other than amounts paid pursuant to clause (A), then due
+ and payable. Upon such payment (i) the obligation of Lessee to make further
+ payments of Basic Rent hereunder shall terminate, (ii) the Term shall
+ terminate with respect to the Aircraft and (iii) Lessor will transfer to
+ Lessee or applicable insurer, free and clear of Lessor's Liens and all other
+ Liens arising by or through Lessor, any Beneficiary or any Lender but
+ otherwise without recourse or warranty, all of Lessor's right, title and
+ interest, if any, in and to the Airframe and Engines (if any) suffering the
+ Casualty Occurrence, as well as all of Lessor's right, title and interest in
+ and to any Engine constituting part of the Aircraft but not installed
+ thereon at the time of the Casualty Occurrence; provided, however, that
+ there shall be excluded from such transfer any and all claims against any
+ Persons which arose prior to the date of such transfer, including without
+ limitation any and all claims against any Persons who may have been
+ responsible, in whole or in part, for the events giving rise to such
+ Casualty Occurrence.
+
+ (b) CASUALTY OCCURRENCE WITH RESPECT TO AN ENGINE. Upon a
+ Casualty Occurrence with respect to an Engine only, Lessee shall give Lessor
+ and each Beneficiary prompt written notice thereof and shall, within forty-five
+ (45) days after such occurrence, convey to Lessor, as replacement for the
+ Engine suffering a Casualty Occurrence, title to a Replacement Engine;
+ PROVIDED, HOWEVER, that such 45-day period shall be extended to 180 days after
+ the occurrence of such Casualty Occurrence if Lessee shall, prior to the end of
+ such 45-day period, have delivered to Lessor or the Beneficiaries all proceeds
+ of the insurance payable with respect to such damaged Engine and the amount of
+ such proceeds is at least equal to the replacement value thereof (as determined
+ reasonably and in good faith by the Beneficiaries). Each Replacement Engine
+ shall be (i) free of all Liens, (ii) in as good an operating condition as the
+ Engine being replaced, assuming the Engine being replaced was in the condition
+ and repair required by the terms hereof immediately prior to the Casualty
+ Occurrence, and (iii) in a condition (including as to the status of all logs,
+ records and technical documents) acceptable to the Beneficiaries in their sole
+ discretion, as evidenced by their written acknowledgement thereof. Prior to or
+ at the time of any such conveyance, Lessee, at its own expense, will promptly
+
+ -48-
+
+
+
+
+
+ (i) furnish Lessor with a full warranty bill of sale, in form and substance
+ reasonably satisfactory to Lessor and each Beneficiary, with respect to such
+ Replacement Engine; (ii) cause a supplement hereto, in form and substance
+ reasonably satisfactory to Lessor and each Beneficiary, subjecting such
+ Replacement Engine to this Lease, to be duly executed by Lessee, and recorded
+ pursuant to applicable Law; (iii) furnish Lessor and each Beneficiary with such
+ evidence of title to such Replacement Engine and of compliance with the
+ insurance provisions of Section 12 hereof with respect to such Replacement
+ Engine as Lessor or such Beneficiary may reasonably request; (iv) if reasonably
+ requested by Lessor or any Beneficiary, furnish Lessor with an opinion of
+ Lessee's counsel to the effect that title to such Replacement Engine has been
+ duly conveyed to Lessor and each Beneficiary, and that such Replacement Engine
+ is duly leased hereunder; (vi) furnish a certificate signed by a duly
+ authorized financial officer or executive of Lessee certifying that, upon
+ consummation of such replacement, no Default will exist hereunder; (vii)
+ furnish Lessor and each Beneficiary with such documents (including but not
+ limited to all technical documents) as Lessor or such Beneficiary may
+ reasonably request in connection with the consummation of the transactions
+ contemplated by this Section 11(b), in each case in form and substance
+ satisfactory to Lessor and such Beneficiary; and (viii) furnish such financing
+ statement covering the Replacement Engine as may be requested by Lessor or any
+ Beneficiary. Upon full compliance by Lessee with the terms of this Section
+ 11(b), Lessor will transfer to Lessee all of Lessor's right, title and interest
+ in the Engine which suffered the Casualty Occurrence free and clear of Lessor's
+ Liens and all other Liens arising by or through Lessor, any Beneficiary or any
+ Lender. For all purposes hereof, each such Replacement Engine shall be deemed
+ part of the property leased hereunder, shall be deemed an "Engine" as defined
+ herein and shall be deemed part of the Aircraft. No Casualty Occurrence covered
+ by this Section 11(b) shall result in any reduction in Rent.
+
+ (c) APPLICATION OF PROCEEDS AND PAYMENTS. Any payments
+ received at any time by Lessor or by Lessee from any insurer under any policy
+ of insurance (other than liability insurance) shall be applied in the manner
+ specified in Section 12(d), 12(e) or 12(f) hereof as applicable. Subject to
+ Section 11(f) hereof, any payments received at any time by Lessor or Lessee
+ from any Governmental Entity or other Person with respect to a Casualty
+ Occurrence will be applied as follows:
+
+ (i) unless clause (ii) below is applicable, so much of such
+ payments as shall not exceed the Casualty Value required to be paid by
+ Lessee
+
+ -49-
+
+
+
+
+
+ pursuant to Section 11(a) of this Lease shall be paid to Lessor in
+ reduction of Lessee's obligation to pay such Casualty Value if not
+ already paid by Lessee or, if already paid by Lessee (unless a Default
+ shall have occurred and be continuing), shall be applied by Lessor to
+ reimburse Lessee for its payment of such Casualty Value and the balance
+ of such payment, if any, remaining thereafter (if such payment is
+ received with respect to insurance other than liability insurance)
+ (unless a Default shall have occurred and be continuing) shall be paid
+ over to, or retained by, Lessee, except to the extent any such amount
+ is specifically allocable to an interest of Lessor; or
+
+ (ii) if such payments are received as a result of a Casualty
+ Occurrence with respect to an Engine which is being replaced pursuant
+ to Section 11(b), unless a Default shall have occurred and be
+ continuing (and except as otherwise contemplated by Section 11(b) if
+ the 45-day period specified for the replacement thereof is to be
+ extended to 180 days, as therein provided), all such payments shall be
+ paid over to, or retained by, Lessee if Lessee shall have fully
+ performed or, concurrently therewith has fully performed, the terms of
+ Section 11(b) and of Section 15 hereof with respect to the Casualty
+ Occurrence for which such payments are made.
+
+ (d) REQUISITION FOR USE BY GOVERNMENT WITH RESPECT TO THE
+ AIRCRAFT. In the event of the requisition for use by a Governmental Entity of
+ the Airframe or any Engine (other than a requisition constituting a Casualty
+ Occurrence), all Lessee's obligations under this Lease with respect to the
+ Airframe or Engine shall continue to the same extent as if such requisition had
+ not occurred. All payments received by Lessor or Lessee from the Governmental
+ Entity for the use of the Airframe or Engine during the Term therefor shall be
+ paid over to, or retained by, Lessee if no Default shall have occurred and be
+ continuing; and all payments received by Lessor or Lessee from the Governmental
+ Entity for the use of such item after the Term therefor shall be paid over to,
+ or retained by, Lessor.
+
+ (e) OTHER DISPOSITIONS. Any amounts not payable to or
+ retainable by Lessee pursuant to this Section 11 or Section 12 hereof because a
+ Default shall have occurred and be continuing shall be held by Lessor and shall
+ be paid over to Lessee when such Default shall cease to be continuing, except
+ that if Lessor shall have theretofore declared this Lease to be in default
+ pursuant to Section 18 hereof, such amounts shall be retained by Lessor and
+ disposed of in
+
+ -50-
+
+
+
+
+
+ accordance with the provisions thereof, with any balance remaining to be paid
+ to Lessee.
+
+ (f) APPLICATION IN DEFAULT. Any amount referred to in clause
+ (i) or (ii) of Section 11(c) which is otherwise payable to Lessee shall not be
+ paid to Lessee, or, if it has been previously paid to Lessee, and not yet
+ applied by Lessee as permitted or required hereunder shall be delivered from
+ Lessee to Lessor if at the time of such payment a Default shall have occurred
+ and be continuing. In such case, all such amounts shall be paid to and held by
+ Lessor as security for the obligations of Lessee or, at the option of Lessor,
+ applied by Lessor toward payment of any of Lessee's obligations at the time due
+ hereunder, as Lessor may elect. At such time as there shall not be continuing
+ any such Default, all such amounts at the time held by Lessor in excess of the
+ amount, if any, which Lessor has elected for application as provided above
+ shall be paid to Lessee.
+
+ Section 12. INSURANCE.
+
+ (a) PUBLIC LIABILITY AND PROPERTY DAMAGE INSURANCE. Lessee
+ will carry and maintain in effect, at its own expense, with Approved Insurers,
+ comprehensive public liability insurance (including, without limitation,
+ contractual liability and passenger legal liability) and property damage
+ insurance with respect to the Aircraft of the type usual and customary by
+ commercial scheduled airline standards for airline carriers operating similar
+ aircraft and providing for no less coverage than is carried by Lessee on
+ similar aircraft in its fleet. Such insurance shall be in an amount not less
+ than the amount applicable to similar passenger aircraft and engines which
+ comprise Lessee's fleet, and in any event not less than the amount under
+ "Public Liability and Property Damage Insurance" as set forth on Exhibit C-2
+ hereto Lessee shall not discriminate against the Aircraft in providing such
+ insurance.
+
+ (b) INSURANCE AGAINST LOSS OR DAMAGE. Lessee, at its own
+ expense, will maintain in effect with Approved Insurers "all-risk" ground and
+ flight aircraft hull insurance (which shall include, but not be limited to,
+ comprehensive war risk and allied perils, hijacking, a disappearance clause and
+ coverage against strikes, riots, commotions or labor disturbances, malicious
+ acts or acts of sabotage and unlawful seizure (including confiscation, arrest,
+ nationalization, seizure, restraint, detention, appropriation, requisition or
+ destruction thereat, by or under authority of any Governmental Entity), or
+ wrongful exercise of control of the Aircraft in flight by a person on board the
+ Aircraft acting without the consent of Lessee) covering the Aircraft and "all
+ risk" coverage insurance with
+
+ -51-
+
+
+
+
+
+ respect to Engines and Parts while not installed on the Aircraft or an
+ aircraft, which in each case is at least as broad as coverage maintained by
+ passenger airlines similarly situated to Lessee and operating similar aircraft
+ and engines which comprise Lessee's fleet (it being understood that the
+ obligations hereby imposed upon Lessee by reference to coverage maintained by
+ other airlines is not intended to result in an increase in the definition of
+ Casualty Value). Such insurance shall be for an amount not less than the
+ Casualty Value for the Aircraft and, where "all-risk" hull and war risk are
+ insured separately, shall, in relation to the applicable policies, incorporate
+ a 50/50 clause based on AVS 103, between the underwriters. Such insurance may
+ include provisions for deductibles in an amount usual and customary by
+ commercial scheduled airline standards for airline carriers operating similar
+ aircraft provided that (i) the amount of such deductibles must be no greater
+ than the lowest deductible amount applying to any B737-25A aircraft in Lessee's
+ fleet and (ii) in no event shall the amount of such deductibles exceed the
+ amount under "Deductible Amount" set forth on Exhibit C-2 hereto.
+
+ (c) REQUIRED POLICY DESIGNATIONS AND PROVISIONS. Each and any
+ policy of insurance obtained and maintained pursuant to this Section, and each
+ and any policy obtained in substitution or replacement for any such policies,
+ shall: (i) designate Lessor as owner of the Aircraft covered thereby, and shall
+ designate Lessor (in its individual capacity and as Owner Trustee), each
+ Beneficiary and their assigns as additional insureds (and, with respect to each
+ policy of insurance obtained and maintained pursuant to Section 12(b) hereof,
+ Beneficiaries as loss payee), as their interests may appear warranted each as
+ to itself no operational interest (but without imposing upon Lessor, any
+ Beneficiary or their assigns, any obligation to pay any premiums for any such
+ policies); (ii) expressly provide that, in respect of the interests of Lessor,
+ each Beneficiary and their assigns, in such policies, the insurance shall not
+ be invalidated by any action or omission of Lessee, and shall insure Lessor,
+ such Beneficiary and their assigns, regardless of any breach or violation of
+ any warranty, declaration or condition contained in such policies by Lessee;
+ (iii) provide that if such insurance is canceled by the Approved Insurers for
+ any reason whatsoever, or is adversely changed in any way with respect to the
+ interests of Lessor, any Beneficiary or their assigns, or if such insurance is
+ allowed to lapse for nonpayment of premium, such cancellation, adverse change
+ or lapse shall not be effective as to Lessor, such Beneficiary and their
+ assigns, for thirty (30) days (seven (7) days or such lesser period as may be
+ applicable in the case of any war risks or allied perils coverage) after
+ receipt by Lessor and such Beneficiary of written notice by such insurer or
+ insurers to
+
+ -52-
+
+
+
+
+
+ Lessor and such Beneficiary of such prospective cancellation, change or lapse,
+ (iv) include coverage for the territorial limits of any country in which the
+ Aircraft may at any time be located; (v) provide that, as against Lessor, each
+ Beneficiary and their assigns, the insurer waives any rights of set-off,
+ counterclaim or any other deduction, whether by attachment or otherwise, and
+ waives any rights it may have to be subrogated to any right of any insured
+ against Lessor, such Beneficiary or their assigns, with respect to the Aircraft
+ to the same extent that Lessee has waived its rights of subrogation by the
+ terms of its agreements to indemnify any such party pursuant to this Lease; and
+ (vi) provide that (a) unless Lessor or any Beneficiary shall provide written
+ notice to the Approved Insurers that an Event of Default shall have occurred
+ and be continuing, any payment in respect of any damage or loss not in excess
+ of $500,000 shall be payable directly to the Lessee or its order; PROVIDED,
+ that Lessor and each Beneficiary shall be given prompt written notice of any
+ payment in respect of any damage or loss to the Aircraft in excess of $150,000
+ and (b) any payment in respect of any damage or loss in excess of $500,000 (or
+ all proceeds whether or not in excess of $500,000 if an Event of Default shall
+ have occurred and be continuing), shall be payable directly to the
+ Beneficiaries or their assignees as loss payees, for the account of all
+ interests. Each such liability policy shall be primary without right of
+ contribution from any other insurance which may be carried by Lessor, any
+ Beneficiary or their assigns, and shall expressly provide that all of the
+ provisions thereof shall operate in the same manner as if there were a separate
+ policy covering each insured, provided that such provisions shall not operate
+ to increase the insurer's limit of liability.
+
+ Lessee shall have the right to carry insurance in reasonable
+ excess of the amounts required hereunder and the proceeds of such excess
+ insurance shall be payable to Lessee; PROVIDED that any such excess insurance
+ shall not prejudice the insurance required to be maintained by Lessee hereunder
+ and Lessee shall, upon request of a Beneficiary, notify the Beneficiaries of
+ the nature and amount of such excess insurance. Similarly, Lessor and each
+ Beneficiary shall have the right to carry additional and separate insurance for
+ its own benefit at its own expense, without, however, thereby limiting Lessee's
+ obligations under this Section 12.
+
+ (d) APPLICATION OF INSURANCE PROCEEDS FOR A CASUALTY
+ OCCURRENCE. It is agreed that insurance payments which arise from any policy of
+ insurance carried by Lessee and received as the result of the occurrence of a
+ Casualty Occurrence shall be applied as follows:
+
+ -53-
+
+
+
+
+
+ (i) if such payments are received with respect to a Casualty
+ Occurrence relating to the Airframe and Engines or engines installed on
+ the Airframe, so much of such payments as shall not exceed the amounts
+ due under Section 11(a) hereof shall be paid to Lessor for immediate
+ application toward sums owed by Lessee, and the balance to Lessee; and
+
+ (ii) if such payments are received with respect to a Casualty
+ Occurrence relating to an Engine under circumstances contemplated by
+ Section 11(b) hereof, such payment shall be paid over to Lessee,
+ provided that Lessee shall have fully performed or, concurrently
+ therewith, fully performs the terms of Section 11(b) hereof.
+
+ (e) APPLICATION OF INSURANCE PROCEEDS FOR OTHER THAN A
+CASUALTY OCCURRENCE. As between Lessor and Lessee all insurance payments in
+excess of $500,000 that are received by Lessor or the Beneficiaries under
+policies required to be maintained by Lessee pursuant to Section 12(b) as a
+result of any property damage or loss to the Airframe or any Engine not
+constituting a Casualty Occurrence, or to any Part will be held by Lessor or
+the Beneficiaries until Lessee furnishes Lessor with satisfactory evidence
+that the repairs or replacement property Lessee is required to perform or
+obtain in accordance with the terms of Section 9 of this Lease have been made
+or obtained by Lessee or, to the extent necessary to enable Lessee to make
+required progress payments in accordance with the workscope relating to the
+repair of the Aircraft, Lessor or the Beneficiaries shall make such interim
+progress payments upon receipt of copies of appropriate invoices or other
+evidence of the completion of the related work or the purchasing of related
+materials in accordance with the terms of such workscope or the related
+repair contract. Upon receipt of such evidence of repair or replacement,
+Lessor shall pay Lessee the amount of the insurance payment received with
+respect to such loss less the amount of any progress payments made to Lessee
+pursuant to this Section 12(e).
+
+ (f) APPLICATION IN DEFAULT. Any amount referred to in
+Section 12(d)(i) or (ii) or Section 12(e) which is otherwise payable to
+Lessee shall not be paid to Lessee, or, if it has been previously paid to
+Lessee, shall be delivered by Lessee to Lessor, if at the time of such
+payment, an Event of Default shall have occurred and be continuing. In either
+case, all such amounts shall be held by Lessor as security for the
+obligations of Lessee or, at the option of Lessor, applied by Lessor toward
+payment of any of Lessee's obligations at the time due hereunder. At such
+time as
+
+
+ -54-
+
+
+
+there shall not be continuing any such Event of Default, all such amounts at
+the time held by Lessor in excess of the amount, if any, which Lessor has
+elected for application as provided above shall be paid to Lessee.
+
+ (g) CERTIFICATES OF INSURANCE. On or before the Delivery
+Date, and thereafter on each renewal by Lessee of the insurance required
+hereby, but not less often than annually, Lessee will furnish to Lessor and
+each Beneficiary a certificate executed and delivered by an Approved Insurance
+Broker who is authorized by an Approved Insurer, appointed by Lessee,
+describing in reasonable detail insurance carried on the Aircraft and
+certifying that the insurance then maintained on the Aircraft complies with
+Section 12 of this Lease. Lessee will cause such Approved Insurance Broker who
+is authorized by an Approved Insurer to agree to advise Lessor and each
+Beneficiary in writing at least thirty (30) days (seven (7) days or such lesser
+period as may be applicable in the case of any war risk and allied perils
+coverage) prior to the termination or cancellation by the underwriters for any
+reason (including, without limitation, failure to pay the premium therefor) of
+any such insurance. Lessee further agrees to cause such Approved Insurance
+Broker (i) to advise Lessor and each Beneficiary in writing (x) as soon as such
+Approved Insurance Broker has knowledge that any insurance coverage carried and
+maintained on the Aircraft pursuant to this Section 12 will not be renewed or
+available upon expiration of the then existing insurance and (y) not later than
+seven (7) days prior to the expiration of the then existing insurance if Lessee
+has not given notice renewal instructions to the Approved Insurance Broker, and
+(ii) to deliver directly to Lessor and each Beneficiary the certificate of
+insurance described above in this paragraph (g) upon such renewal.
+
+ (h) Any insurance described above shall be placed and
+maintained throughout the Term in the London, Tokyo, United States, French or
+German aviation insurance markets with Approved Insurers, and Lessee's
+obligations under this Section 12 shall not be terminated or diminished in any
+respect for any reason, including any subleasing of the Aircraft; PROVIDED,
+HOWEVER, that if, in connection with any sublease of the Aircraft permitted
+hereby, the Permitted Sublessee is required by law to place or maintain some or
+any part of the insurance required hereby in an aviation insurance market other
+than the London, Tokyo, United States, French or German aviation insurance
+market, then Lessee shall cause such Permitted Sublessee to place and maintain
+in the London, Tokyo or United States aviation insurance market re-insurance
+policies fully covering such insurance, and any such re-insurance policy shall
+contain a "cut through" clause in form, scope and substance reasonably
+satisfactory to Lessor and each Beneficiary. In the event
+
+
+ -55-
+
+
+
+of any sublease of the Aircraft, Lessee shall cause to be delivered to Lessor
+and to each Beneficiary at least five Business Days prior to the commencement
+of such sublease, appropriate certificates of insurance and re-insurance
+complying with the requirements of CLAUSE (g) above.
+
+ (i) Notwithstanding anything in this Section 12 to the
+contrary, during the period of any CRAF activation contemplated in Section
+11(d) of this Lease, Lessor will accept the indemnification by the full faith
+and credit of the United States government in lieu of the insurance coverage
+required by this Section 12; provided, however, that (i) such indemnification
+by the United States government shall provide coverage against the same risks
+and on the terms as the risks and terms required by Section 12, (ii) such
+indemnification shall be in amounts that are not less than the insurance
+coverage contemplated in this Section 12, and (iii) Lessee shall not subject
+the Aircraft to the CRAF program without the Beneficiaries, prior written
+consent.
+
+ Section 13. INDEMNIFICATION.
+
+ Subject only to the limitations described in the last
+paragraph of this Section 13, Lessee agrees to indemnify, reimburse, hold
+harmless, protect and defend each Indemnitee for, from and against any and all
+claims, damages, losses, liabilities, demands, suits, judgments, causes of
+action, legal proceedings, whether civil or criminal, penalties, fines and
+other sanctions, and any reasonable attorney's fees and other reasonable costs
+and expenses in connection herewith or therewith, including any of the
+foregoing arising or imposed with or without Lessor's or Beneficiaries' fault
+or negligence (whether passive or active) or under the doctrine of strict
+liability (any and all of which are hereafter referred to as "Claims") which in
+any way may result from, pertain to or arise in any manner out of, or are in
+any manner related to (i) the Aircraft or any this Lease or Operative Documents
+or any document executed in connection herewith, or the breach of any
+representation, warranty or agreement made by Lessee hereunder or under any
+other such document, or (ii) the condition, manufacture, re-delivery, lease,
+acceptance, rejection, possession, return, disposition, storage, maintenance,
+use or operation of the Aircraft either in the air or on the ground, or (iii)
+any defect in the Aircraft (whether or not discovered or discoverable by Lessee
+or Lessor or any Beneficiary) arising from the material or any articles used
+therein or from the design, testing or use thereof or from any maintenance,
+service, repair, overhaul or testing of the Aircraft, whether or not the
+Aircraft is in the possession of Lessee, and regardless of where the Aircraft
+may then be located, or (iv) any transaction,
+
+
+ -56-
+
+
+
+approval or document contemplated by this Lease, Operative Documents or given
+or entered into in connection herewith; provided, however, that Lessee shall be
+subrogated to all rights and remedies which Lessor may have against the
+Manufacturer of the Aircraft and its subcontractors or any other party as to
+any such Claims, but only to the extent that Lessee satisfies its
+indemnification to the Indemnitees with respect to such Claims. Nothing herein
+shall require Lessee to indemnify any Indemnitee in respect of any Claim to the
+extent the facts or circumstances that form the basis for such Claim arose or
+existed prior to the Delivery Date, unless such Claim or any losses, costs
+(including attorneys, fees or expenses) or damages arise or are increased as a
+result of a breach by Lessee of its agreements herein or otherwise relate to
+such a breach (including the breach of any obligation to remedy a fact or
+circumstance that arose or existed prior to the Delivery Date). In the event
+Lessee is required to indemnify any Indemnitee hereunder, Lessee shall, upon
+demand, pay to such Indemnitee an amount which, after deduction of all Taxes
+and like charges required to be paid by such Indemnitee in respect of such
+payment, is equal to the amount of the indemnification required; provided,
+however, that Lessee shall not be required to pay or discharge any Claim
+brought by a third party so long as the validity or the amount thereof shall be
+diligently contested in good faith and on reasonable grounds by Lessee, at no
+cost or expense to Lessor.
+
+ Subject to Lessee's rights under Section 20(f), Lessee hereby
+waives, and releases each Indemnitee from, any Claims (whether existing now or
+hereafter arising) for or on account of or arising or in any way connected with
+injury to or death of personnel of Lessee or loss or damage to property of
+Lessee or the loss of use of any property which may result from or arise in any
+manner out of or in relation to the ownership, leasing, condition, use or
+operation of the Aircraft, either in the air or on the ground, or which may be
+caused by any defect in the Aircraft from the material or any article used
+therein or from the design or testing thereof, or use thereof, or from any
+maintenance, service, repair, overhaul or testing of the Aircraft regardless of
+when such defect may be discovered, whether or not the Aircraft is at the time
+in the possession of Lessee, and regardless of the location of the Aircraft at
+any such time.
+
+ The indemnities contained in this Section 13 shall continue
+in full force and effect notwithstanding the expiration or other termination of
+this Lease and are expressly made for the benefit of and shall be enforceable
+by each Indemnitee; PROVIDED, that, unless an Event of Default shall have
+occurred and be continuing, Lessee shall not be obligated to pay any indemnity
+pursuant to this
+
+
+ -57-
+
+
+
+Section 13 with respect to any amount to the extent that such amount arises out
+of or is measured by acts, failures to act, events or periods of time (or any
+combination of the foregoing) that occur after the Aircraft has been
+redelivered to Lessor pursuant to and in accordance with Section 16 hereof
+(under circumstances not involving a repossession pursuant to Section 18
+hereof) and is no longer subject to this Lease and all obligations of the
+Lessee under this Lease have been discharged (other than obligations which by
+their express terms survive the expiration of the Term of this Lease) unless
+any such act or event shall itself result from or be attributable to an act or
+omission of Lessee which occurred prior to the redelivery of the Aircraft and
+the discharge of Lessee's obligations under the Lease.
+
+ Notwithstanding the foregoing provisions of this Section 13,
+Lessee shall not be obligated to make any payment by way of indemnity to any
+Indemnitee in respect of any Claims to the extent such Claims result from the
+willful misconduct or gross negligence of such Indemnitee or to the extent
+relating solely to the breach or misrepresentation of Lessor or a Beneficiary
+under an Operative Document.
+
+ Section 14. LIENS.
+
+ Lessee shall not directly or indirectly create, incur,
+assume or suffer to exist any Lien on or with respect to the Aircraft or
+Engines, title thereto or any interest therein, except (i) the respective
+rights of Lessor and Lessee as herein provided; (ii) Lessor's Liens or any
+other Lien arising by or through Lessor, a Beneficiary or a Lender with
+respect to the Aircraft or Engines; (iii) Liens for Taxes either not yet due
+or being contested in accordance with Section 10 hereof, so long as adequate
+reserves are maintained with respect to such Liens and so long as the
+Aircraft or such Engine is not in danger of being lost, sold, confiscated,
+forfeited or seized as a result of any such Lien or contest; and (iv)
+inchoate materialmen's, mechanics', workmen's, repairmen's, employees' or
+other like Liens arising in the ordinary course of business, which either are
+not due and owing or are being contested in good faith by Lessee so long as
+the Aircraft or such Engine is not in danger of being lost, sold,
+confiscated, forfeited or seized as a result of any such Lien or contest.
+Lessee shall promptly, at its own expense, take such action as may be
+necessary to duly discharge any Lien (except for the Liens referred to in
+clauses (i), (ii), (iii) and (iv) of this Section 14) if the same shall arise
+at any time with respect to the Aircraft or any Engine (including any Part).

+ Section 15. PERFECTION OF TITLE AND FURTHER ASSURANCES.
+
+ If at any time, any filing or recording is reasonably
+necessary to protect the interests of Lessor or the Beneficiaries, Lessee, upon
+request by Lessor or any Beneficiary, shall cause this Lease and any and all
+additional instruments which shall be executed pursuant to the terms hereof, to
+be kept, filed and recorded and to be re-executed, re-filed and re-recorded in
+the appropriate office or offices pursuant to applicable Laws, to perfect,
+protect and preserve the rights and interests of Lessor hereunder and in the
+Aircraft. At the reasonable request of Lessor or any Beneficiary, Lessee shall
+furnish to Lessor and each Beneficiary an opinion of counsel or other evidence
+satisfactory to Lessor of each such filing or re-filing and recordation or
+re-recordation. All costs (including attorneys' fees and expenses) relating to
+effecting and maintaining the registration of this Lease, including the Lease
+Supplement, or any related document, shall be borne and paid by Lessee. All
+costs (including attorneys' fees and expenses) relating to effecting and
+maintaining the registration of the Aircraft with the FAA shall be borne and
+paid by Lessor or the Beneficiaries, provided that Lessee shall cooperate with
+Lessor and the Beneficiaries in connection therewith as provided above and bear
+the cost of changing the registration number of the Aircraft.
+
+ Without limiting the foregoing, Lessee shall do or cause
+to be done, at Lessee's cost and expense, any and all acts and things which
+may be required under the terms of the Mortgage Convention to perfect and
+preserve the title and interest of Lessor in the Aircraft within the
+jurisdiction of any signatory which has ratified the Mortgage Convention if
+such jurisdiction is in the territory in which Lessee intends to operate the
+Aircraft, as Lessor or any Beneficiary may reasonably request. Lessee shall
+also do or cause to be done, at its own expense, any and all acts and things
+which may be required of an aircraft operator under the terms of any other
+Law involving any jurisdiction in which Lessee intends to operate, or any and
+all acts and things which Lessor or any Beneficiary may reasonably request,
+to perfect and preserve Lessor's ownership rights regarding the Aircraft
+within any such jurisdiction.
+
+ In addition, Lessee will promptly and duly execute and
+deliver to Lessor such further documents and assurances and take such further
+actions as it may from time to time reasonably request in order to more
+effectively carry out the intent and purpose of this Lease and to establish
+and protect the rights and remedies created or intended to be created in
+favor of Lessor hereunder, including, without limitation, if reasonably
+requested by Lessor at the expense
+
+
+ -59-
+
+
+
+of Lessee, the execution and delivery or supplements or amendments hereto in
+recordable form, subjecting to this Lease any Replacement Engine and the
+recording or filing of counterparts thereof, in accordance with the Laws of any
+appropriate jurisdiction.
+
+ Section 16. RETURN OF AIRCRAFT AND RECORDS.
+
+ (a) RETURN.
+
+ (i) On the Return Occasion, Lessee will, unless Casualty
+ Occurrence has occurred, at its expense, redeliver the
+ Aircraft to Lessor at the Return Location in a condition
+ complying with the requirements of Exhibit E and this
+ Section 16:
+
+ (A) free and clear of all Liens (other than Lessor's Liens
+ or any Lien arising by or through Lessor, any Beneficiary
+ or any Lender);
+
+ (B) having the benefits of any indemnities and warranties
+ which have been assigned to and are held by Lessee
+ relating to the Aircraft assigned to Lessor;
+
+ (C) duly registered in the name of Lessor with the FAA;
+
+ (D) unless otherwise agreed by the Beneficiaries in a
+ condition so as to ensure the Aircraft has either a
+ current, valid and existing certification of
+ airworthiness for airline operation or (at the
+ Beneficiaries, election) an export certificate of
+ airworthiness, in either case, issued by the FAA; and
+
+ (E) if specified by the Beneficiaries, Lessee shall cooperate
+ with Lessor to ensure that the Aircraft is deregistered
+ from the FAA;
+
+ provided that Lessee complies with the foregoing and with all
+ of its obligations under this Lease, Lessor shall technically
+ accept redelivery of the Aircraft from Lessee at Lessee's
+ maintenance facilities in Honolulu, Hawaii before the
+ commencement of any storage period (it being understood that
+ if during the ferry flight to the Return Location any defect
+ or non-compliance which was purportedly corrected in connection
+ with the Final Inspection shall reoccur, Lessee shall be
+ responsible for rectifying such defect or non-compliance);
+ PROVIDED, HOWEVER, that if a C Check shall be performed in
+ connection with the Return
+
+
+ -60-
+
+
+ Occasion, then such technical inspection and acceptance shall
+ occur at the location of the facility in the United States of
+ America or Canada approved by FAA for C Check of 737-200
+ aircraft at which such C Check is performed.
+
+ (ii) In the event that Lessee does not return the Aircraft to
+ Lessor on the specified date of expiration or earlier
+ termination of this Lease, for any cause (other than due
+ to the fault of Lessor, any Beneficiary or the Lender),
+ then the obligations of Lessee under this Lease shall
+ continue and such continued use shall not be considered a
+ renewal of the terms of this Lease or a waiver of any
+ right of Lessor hereunder and Lessor may terminate
+ Lessee's right as to the Aircraft on written notice to
+ Lessee and Lessee shall fully indemnify Lessor, the
+ Lender and each other Indemnitee on demand against all
+ losses, liabilities, actions, proceedings, costs and
+ expenses thereby suffered or incurred by Lessor, the
+ Lender or any other Indemnitee. During such continued
+ use, damages in an amount equal to Basic Rent (as
+ provided below) shall continue to be paid by Lessee to
+ Lessor, and the performance of other obligations of
+ Lessee to Lessor shall continue hereunder. Basic Rent
+ shall be pro-rated on a daily basis for each day until
+ the Aircraft is actually delivered to Lessor, and all
+ other terms and conditions of this Lease shall remain in
+ full force and effect. Payment shall be made promptly
+ upon presentation of Lessor's invoice and any failure to
+ pay shall constitute a default of Lessee.
+
+ (b) FINAL INSPECTION. At least 10 days prior to redelivery of the
+Aircraft, Lessee will take the Aircraft out of service and make the Aircraft
+and all Aircraft Documents available to Lessor and the Beneficiaries for
+inspection at Lessee's facilities in Honolulu, Hawaii (or at the location of
+the facility in the United States of America or Canada approved by FAA for
+the C Check of 737-200 aircraft at which the C Check shall be performed, as
+provided in Section 16(a)(i) above, if applicable) (the "Final Inspection")
+in order to verify that the condition of the Aircraft complies with this
+Lease, and Lessor's and the Beneficiaries, representatives shall use their
+reasonable efforts to cause their representatives to commence such compliance
+verification as promptly as practicable at or following the beginning of such
+10-day period. Lessee agrees, at the Beneficiaries, request, to furnish due
+evidence that all service, maintenance, repairs, overhauls and modifications
+required under this Lease have been duly
+
+
+ -61-
+
+
+
+performed. Lessee shall make available to Lessor and the Beneficiaries at
+Lessee's principal maintenance base, not less than fifteen (15) Business Days
+prior to commencement of the Final Inspection, such documentation regarding the
+condition, use, maintenance, operation and history of the Aircraft during the
+Term, as requested by the Beneficiaries in order to enable Lessor and the
+Beneficiaries to verify that the condition of the Aircraft complies with this
+Lease. To the fullest extent possible, the Final Inspection shall be carried
+out during the C Check referred to in paragraph 2(a) of Exhibit E. The Final
+Inspection will consist of and be long enough to permit Lessor and the
+Beneficiaries to:
+
+ (i) generally review, test (as observer) and inspect the
+ Aircraft to Lessor's and the Beneficiaries, satisfaction
+ (which will include the opening of any areas of the
+ Aircraft if Lessor or the Beneficiaries reasonably
+ believe, based on prior inspections or other evidence,
+ that the opening of such areas would reveal that the
+ Aircraft does not completely comply with the requirements
+ of Exhibit E and this Section 16), to satisfy Lessor and
+ the Beneficiaries that the Aircraft completely complies
+ with the requirements of Exhibit E and this Section 16;
+
+ (ii) inspect the Aircraft Documents;
+
+ (iii) inspect the un-installed Parts;
+
+ (iv) observe a two hour demonstration flight (with up to four
+ of Lessor's or the Beneficiaries' representatives as
+ on-board observers);
+
+ (v) inspect the Engines, including, without limitation (i) by
+ observing a performance test in accordance with limits set
+ forth in the engine section of the Aircraft Maintenance
+ Manual and (ii) by performing a full and complete
+ borescope inspection of (a) the low pressure and high
+ pressure compressors and (b) turbine area; and
+
+ (vi) inspect the APU, including, without limitation (i) an APU
+ condition run (as observer) and (ii) by a full and
+ complete borescope inspection.
+
+The actions contemplated by the foregoing clauses (i) through (iv) shall be
+performed at Lessee's expense; provided that, unless an Event of Default
+shall have
+
+
+ -62-
+
+
+
+occurred or any inspection carried out under the foregoing clauses (i)
+through (iv) reveals discrepancies which require a further inspection, Lessee
+shall not be required to bear the travel and lodging expenses of Lessor's or
+the Beneficiaries, representatives.
+
+ (c) NON-COMPLIANCE. To the extent that, at the time of Final
+Inspection, the condition of the Aircraft does not comply with this Lease,
+Lessee will at the Beneficiaries, option:
+
+ (i) immediately rectify the non-compliance and, to the
+ extent the non-compliance extends beyond the Return
+ Occasion, the Term will be automatically extended
+ (including the obligation to pay Rent as referred to
+ in Section 16(a)(ii)) and this Lease will remain in
+ force until the non-compliance has been rectified; or
+
+ (ii) redeliver the Aircraft to Lessor and pay to Lessor
+ such amount as is mutually agreed to put the Aircraft
+ into the condition required by this Lease. Lessor
+ shall make all reasonable efforts to minimize such
+ costs.
+
+ (d) REDELIVERY. If applicable, upon redelivery Lessee will
+provide to Lessor and the Beneficiaries all documents (other than those as may
+be required to be supplied by Lessor or the Beneficiaries) necessary to export
+the Aircraft from the United States (including, without limitation, a valid and
+subsisting export license, if applicable, for the Aircraft) and required in
+relation to the deregistration of the Aircraft with the FAA.
+
+ In the event that Beneficiaries request Lessee to secure an
+export license (a) such request must be made upon sufficient notice in order to
+grant Lessee adequate time to procure such export license, (b) Lessor will
+render such timely assistance as is reasonably necessary, and (c) this may be
+requested in relation to the Return Occasion or subsequent to the Return
+Occasion.
+
+ (e) ACKNOWLEDGEMENT. Upon return of the Aircraft in
+accordance with the terms of this Lease, Lessor shall execute and deliver a
+Redelivery Acknowledgement in the form of Exhibit I hereto to Lessee.
+
+ (f) MAINTENANCE PROGRAM.
+
+ (i) Prior to the Return Occasion (unless the Aircraft has
+ suffered a Casualty Occurrence) and upon Lessor's or a
+ Beneficiary's request,
+
+
+ -63-
+
+
+
+ Lessee will provide Lessor or such Beneficiary or its
+ agent, in either case at Lessee's cost, reasonable
+ access to the Maintenance Program and the Aircraft
+ Documents in order to facilitate the Aircraft's
+ integration into any subsequent operator's fleet.
+
+ (ii) Lessee will, if requested by Lessor or a Beneficiary
+ to do so, upon return of the Aircraft deliver to
+ Lessor or the Beneficiaries a certified true, current
+ and complete copy of the Maintenance Program in
+ English. Lessor and the Beneficiaries agree that they
+ will not disclose the contents of the Maintenance
+ Program to any person or entity except to the extent
+ necessary to monitor Lessee's compliance with this
+ Lease and/or to bridge the maintenance program for the
+ Aircraft from the Maintenance Program to another
+ maintenance program after the Return occasion.
+
+ (g) FUEL. The amount of fuel in the Aircraft shall be no less
+than the amount of fuel upon Delivery Date. If requested by Lessor, Lessee will
+fuel the Aircraft in excess of the required amount by the preceding sentence at
+the Return Location, and Lessor will pay for the fuel exceeding such
+requirement on board the Aircraft on the Return Occasion at the direct cost
+paid by Lessee (without mark-up).
+
+ (h) STORAGE. If the Final Inspection is carried out in
+Honolulu, Hawaii and a Beneficiary requests in writing then Lessee shall, at
+Lessee's cost and expense during the first sixty (60) days and thereafter
+Lessor's cost and expense, provide Lessor with, or assist Lessor in procuring,
+storage facilities for the Aircraft for up to one hundred twenty (120) days.
+Such storage shall be at Lessee's maintenance base or if such maintenance base
+will be eventually unable to perform the required maintenance, any other
+location agreed between Lessor and Lessee which base or location is capable of
+performing any required maintenance on the Aircraft. With respect to the
+Aircraft while in storage, Lessee will maintain, or procure the maintenance
+of, an amount of fuel in each tank as required in accordance with the storage
+procedures at the storage location and as set forth herein. Lessee agrees,
+during such storage period, to perform, or procure the performance of, such
+maintenance required to maintain the airworthiness of the Aircraft (i) in
+accordance with the storage procedures prescribed by the Manufacturer or
+Lessee's Maintenance Program and (ii) in a condition required to be
+
+
+ -64-
+
+
+
+maintained at redelivery pursuant to the terms of Section 16(a). Risk of loss
+or damage to the Aircraft shall pass to Lessor at the commencement of storage,
+but Lessee will carry insurance, with Lessor and each Beneficiary named as an
+additional insured, on the Aircraft during such storage period as though the
+Aircraft were to remain in Lessee's fleet in accordance with the provisions of
+Section 12, except that Lessee shall not be required to maintain "all risks"
+flight insurance during such storage period but shall maintain insurance
+policies that cover the Aircraft in storage and test flights of the Aircraft on
+an hourly basis (as typically available and maintained under similar
+circumstances involving the storage and maintenance of aircraft). All amounts
+hereunder relating to storage, insurance and maintenance work for the first 60
+days of such storage period shall be for the account of Lessee and thereafter,
+shall be for the account of Lessor. Incremental costs incurred by Lessee after
+the first 60 days of storage which would not have been incurred had such
+storage period not exceeded 60 days shall be reimbursed by Lessor. Lessee
+further agrees to perform, or procure the performance of, at Lessor's cost, any
+other maintenance that Lessor may reasonably request. If, following the storage
+of the Aircraft in Hawaii, the Beneficiaries ferry the Aircraft to a location
+designated by the Beneficiaries in the Western Continental United States (the
+"Designated Location"), Lessee will reimburse the Beneficiaries for the cost of
+the ferry flight of the Aircraft from the storage location in Hawaii to such
+Designated Location. If the Aircraft is ferried to a location other than in the
+Western Continental United States, other than following a Default or an Event
+of Default, then (i) the Beneficiaries will bear any additional ferry flight
+costs and expenses incurred that are beyond the costs and expenses that would
+have been incurred if the Aircraft were ferried to a location in the Western
+Continental United States, and (ii) Lessee will bear the ferry flight costs and
+expenses that are equivalent to the ferrying of the Aircraft to a location in
+the Western Continental United States and shall pay such amount to Lessor or
+the Beneficiaries upon demand by Lessor or the Beneficiaries therefor.
+
+ (i) MAINTENANCE FOR RE-REGISTRATION. Lessee, at Lessee's
+cost, will, upon written notice from a Beneficiary not less than sixty (60)
+days prior to a Return Occasion, carry out such extra maintenance, repair or
+modification as may be required to enable the Aircraft to be in a condition
+to ensure that the Aircraft will meet and comply with (i) the requirements of
+any other country selected by the Beneficiaries and (ii) all civil aviation
+regulations, orders, rules and airworthiness directives of such country to
+permit the immediate re-registration and securing of a certificate of
+airworthiness in such country for the
+
+ -65-
+
+
+
+Aircraft (provided such regulations, orders, rules and airworthiness directives
+are no more restrictive than those of the FAA, and, so long as Lessee is
+otherwise in compliance with this Section 16 and Exhibit E, the time required
+to perform such extra maintenance shall not constitute an extension of the
+Term). If the cost of such maintenance, repair or modification exceeds the cost
+of the maintenance, repair or modification which Lessee would otherwise have
+incurred to ensure the Aircraft shall be in condition to comply with the terms
+of this Lease, Lessor shall promptly pay Lessee the difference between such
+costs at actual cost (without mark-up) to Lessee.
+
+ (j) ASSISTANCE FOR FUTURE LEASING/SALE.
+
+ (i) Lessor or any Beneficiary may, from time to time
+ during the last year of the Term, wish to make the
+ Aircraft available for inspection to designated
+ representatives or technical teams evaluating the Aircraft
+ for use after the end of the Term. Lessor or any
+ Beneficiary agrees to give Lessee not less than five (5)
+ days, advance notice of such inspection and Lessee agrees
+ to co-operate fully with Lessor's or such Beneficiary's
+ requests in making the Aircraft and Aircraft Documents
+ available to such authorized technical team. Lessor agrees
+ to be responsible for its costs in connection with any
+ such inspection and that such request will be reasonable
+ and will be coordinated with Lessee so as not to
+ unreasonably interfere with the operation or maintenance
+ of the Aircraft or the conduct of Lessee's business
+ (unless an Event of Default shall have occurred and be
+ continuing); PROVIDED, HOWEVER, that, unless an Event of
+ Default shall have occurred and be continuing, no such
+ inspection shall result in the delay of a scheduled flight
+ of Lessee;
+
+ (ii) Subject to prior coordination between the
+ Beneficiaries and Lessee, Lessee agrees that, during the
+ last year of the Term and following redelivery of the
+ Aircraft to Lessor, Lessee shall at any Beneficiary's
+ reasonable request and Lessee's cost make available to
+ Lessor and the Beneficiaries for such reasonable period as
+ the Beneficiaries may reasonably require technical and
+ engineering personnel qualified to provide the
+ Beneficiaries and any subsequent lessee or purchaser of
+ the Aircraft with such information as will enable any
+ subsequent lessee or purchaser of the Aircraft to be able
+ to bridge the Aircraft onto the maintenance program of
+ such subsequent lessee or purchaser.
+

+sequestration remains in effect, undismissed, unstayed or unvacated for a
+period of sixty (60) days after the date of entry thereof;
+
+ (j) A petition against Lessee in a proceeding under the

+
+ Upon the occurrence of any Event of Default and any time

+and without notice to Lessee, exercise one or more of the following remedies as
+Lessor in its sole discretion shall elect, to the extent available and
+permitted by, and subject to compliance with any mandatory requirements of,
+applicable Law then in effect:
+
+ (a) Demand that Lessee, and Lessee shall upon the written
+demand of Lessor and at Lessee's expense, immediately return the Aircraft to
+Lessor at any location in Hawaii or in the continental United States as
+specified by Lessor or the Beneficiaries and in the manner specified in such
+notice and in the condition specified in Section 16, in which event such return
+shall not be delayed for purposes of complying with the return conditions
+specified in Section 16 hereof (none of which conditions shall be deemed to
+affect Lessor's possession of the Aircraft) or delayed for any other reason.
+Notwithstanding the foregoing, at Lessor's option Lessee shall be required
+thereafter to take such actions as would be required by the provisions of this
+Lease if the Aircraft were being returned at the end of the Term hereof. In
+addition, Lessor, at its option and to the extent permitted by applicable Law,
+may enter upon the premises where all or any part of the Aircraft is located
+
+
+ -69-
+
+
+
+and take immediate possession of and, at Lessor's sole option, remove the same
+(and/or any engine which is not an Engine but which is installed on the
+Airframe, subject to the rights of the owner, lessor or secured party thereof)
+by summary proceedings or otherwise, all without liability accruing to Lessor
+or any Beneficiary for or by reason of such entry or taking of possession
+whether for the restoration of damage to property, or otherwise, caused by such
+entry or taking, provided that all actions of Lessor in this respect are
+reasonable in the circumstances and excepting damages caused by gross
+negligence or willful misconduct.
+
+ (b) Sell at private or public sale, as Lessor may determine,
+or hold, use, operate or lease to others the Aircraft as Lessor in its sole
+discretion may determine, all free and clear of any rights of Lessee; PROVIDED,
+HOWEVER, that nothing herein shall be construed as limiting any right of Lessor
+or any Beneficiary to sell, lease, assign or otherwise dispose of all or any
+part of the Aircraft under any circumstances (whether or not during the
+existence or continuance of an Event of Default) during the Term, subject only
+to Lessee's rights under SECTION 20(f).
+
+ (c) Whether or not Lessor shall have exercised, or shall
+thereafter at any time exercise, any of its rights under paragraph (a) or
+paragraph (b) of this Section 18, Lessor, by thirty (30) days written notice to
+Lessee specifying a payment date, may demand that Lessee pay to Lessor, and
+Lessee shall pay to Lessor, on the payment date specified in such notice, as
+liquidated damages for loss of bargain and not as a penalty (in lieu of the
+Basic Rent due for the period commencing after the date specified for payment
+in such notice), any unpaid Rent for the Aircraft (prorated in the case of
+Basic Rent on a daily basis) to and including the payment date specified in
+such Notice, plus the aggregate amount of all payments of Basic Rent for the
+remainder of the Term, discounted periodically (equal to installment frequency)
+to present worth at the interest rate of four percent (4%) per annum.
+
+ (d) In the event Lessor, pursuant to Section 18(b) above,
+shall have sold the Aircraft, then Lessor, in lieu of exercising its rights
+under Section 18(c) above, may, if it shall so elect, demand that Lessee pay
+Lessor, and Lessee shall pay to Lessor, as liquidated damages for loss of
+bargain and not as a penalty (in lieu of the Basic Rent due for the period
+commencing after such sale occurs), any unpaid Rent for the Aircraft due to and
+including the date of sale, plus the amount by which the Appraised Value (as
+hereafter defined) of the Aircraft, computed as of the date of such sale,
+exceeds the net cash proceeds of such sale. As used herein, "Appraised Value"
+means the fair market sales value of the Aircraft, as determined by an
+internationally recognized aircraft appraiser selected by the Beneficiaries (i)
+on the basis of either a physical inspection of the Aircraft or on the basis of
+a "desk top"
+
+
+ -70-
+
+
+
+appraisal, as the Beneficiaries shall determine, (ii) on the assumption that
+the Aircraft has been maintained in accordance with the requirements of this
+Lease and is in the condition required by Section 16 and Exhibit E, whether or
+not any such assumption is in fact the case, and (iii) at Lessee's cost and
+expense.
+
+ (e) De-register the Aircraft from the Aircraft Registry at
+the FAA, and proceed to re-register the Aircraft with the FAA or any other
+aircraft registry of any jurisdiction, in any case, in the name of Lessor,
+either or both Beneficiaries or any other Person, as the Beneficiaries shall
+determine.
+
+ (f) In the event that Lessor, pursuant to Section 18(b)
+above, shall, after having exercised reasonable efforts under the
+circumstances, have re-let the Aircraft under a lease which extends at least to
+the date upon which the Term for the Aircraft would have expired but for
+Lessee's default, Lessor, in lieu of exercising its rights under Section 18(c)
+above with respect to the Aircraft, may, if it shall so elect, demand that
+Lessee pay Lessor, and Lessee shall pay Lessor, as liquidated damages for loss
+of bargain and not as a penalty (in lieu of the Basic Rent for the Aircraft due
+after the time of re-letting) any unpaid Rent for the Aircraft due up to the
+date of re-letting, plus the amount, if any, by which the aggregate Basic Rent
+for the Aircraft (such Basic Rent being computed on the assumption that the
+Basic Rent as in effect on the date of such demand shall remain in effect at
+all times thereafter), which would otherwise have become due over the Term,
+discounted periodically (equal to installment frequency) to present worth as of
+the date of re-letting at the interest rate of four percent (4%) per annum,
+exceeds the aggregate basic rental payments to become due under the re-letting
+from the date of such re-letting to the date upon with the Term for the
+Aircraft would have expired but for Lessee's default, discounted periodically
+(equal to installment frequency) to present worth as of the date of the
+re-letting at the interest rate of four percent (4%) per annum.
+
+ (g) Proceed by appropriate court action or actions, either at
+law or in equity, to enforce performance by Lessee of the applicable covenants
+of this Lease and to recover damages for the breach thereof and to rescind this
+Lease.
+
+ (h) Terminate Lessee's right to possession and use of the
+Aircraft under this Lease by written notice (which notice shall be effective
+upon dispatch) and repossess the Aircraft, whereupon, Lessee shall forthwith
+deliver the Aircraft and all Aircraft Documents to Lessor or the Beneficiaries
+at such location as Lessor or the Beneficiaries shall specify.
+
+
+ -71-
+
+
+
+ (i) Seize or foreclose upon any collateral pledged to secure
+the obligations of Lessee hereunder; liquidate, dispose of, and realize upon
+any such collateral; and apply the proceeds thereof to the obligations of
+Lessee hereunder, in any case, as Lessor shall determine.
+
+ (j) Draw any amount available to be drawn under any Security
+Deposit or the Security Letter of Credit, and to apply the proceeds thereof to
+the obligations of Lessee hereunder, in any case, as Lessor shall determine.
+
+ In addition to the foregoing, Lessee shall be liable for any
+and all unpaid Rent during or after the exercise of any of the aforementioned
+remedies, together with interest on such unpaid amounts at the Overdue Rate,
+and until satisfaction of all of Lessee's obligations to Lessor hereunder and
+for all reasonable legal fees and other reasonable costs and expenses incurred
+by Lessor by reason of the occurrence of any Event of Default or the exercise
+of Lessor's remedies with respect thereto, including all costs and expenses
+incurred in connection with the return of the Aircraft in accordance with the
+terms of Section 16 hereof or in placing the Aircraft in the condition and with
+airworthiness certification as required by such Section.
+
+ In effecting any repossession, each of Lessor and each
+Beneficiary and its representatives and agents, to the extent permitted by law,
+shall: (i) have the right to enter upon any premises where it reasonably
+believes the Aircraft, the Airframe, an Engine or Part to be located and Lessee
+shall cooperate in giving Lessor such access; (ii) not be liable, in conversion
+or otherwise, for the taking of any personal property of Lessee which is in or
+attached to the Aircraft, the Airframe, an Engine or Part which is repossessed;
+provided, however, that Lessor shall return to Lessee all personal property of
+Lessee or its passengers which were on the Aircraft at the time Lessor re-takes
+possession of the Aircraft; (iii) not be liable or responsible, in any manner,
+for any inadvertent damage or injury to any of Lessee's property in
+repossessing and holding the Aircraft, the Airframe, an Engine or Part, except
+for that caused by or in connection with Lessor's gross negligence or willful
+acts; and (iv) have the right to maintain possession of and dispose of the
+Aircraft, the Airframe an Engine or Part on any premises owned by Lessee or
+under Lessee's control.
+
+ If requested by Lessor, Lessee, at its sole expense, shall
+assemble and make the Aircraft, the Airframe, an engine or Part available at a
+place designated by Lessor in accordance with Section 16 hereof. Lessee hereby
+agrees that, in the event of the return to or repossession by Lessor of the
+Aircraft, the Airframe, an Engine or Part, any rights in any warranty (express
+or implied) heretofore assigned to Lessee or otherwise held by Lessee shall
+without further act, notice or writing be assigned or-reassigned to
+
+
+ -72-
+
+
+
+Lessor, if assignable. Lessee shall be liable to Lessor for all reasonable
+expenses (including reasonable attorneys, fees and expenses), disbursements,
+costs and fees incurred in (i) re-possessing, storing and shipping the
+Aircraft, the Airframe, an Engine or Part and maintaining, repairing and
+refurbishing the Aircraft, the Airframe, an Engine or Part to the condition
+required by Section 16 hereof and (ii) preparing the Aircraft, the Airframe, an
+Engine or Part for sale or lease, advertising the sale or lease of the
+Aircraft, the Airframe, an Engine or Part and selling or releasing the
+Aircraft, the Airframe, an Engine or Part. Lessor is hereby authorized and
+instructed, at its option, to make reasonable expenditures which Lessor
+considers advisable to repair, restore, store, insure or maintain the Aircraft,
+the Airframe, an Engine or Part to the condition required by Section 16 hereof,
+all at Lessee's sole expense.
+
+ Lessee shall cooperate reasonably and in good faith with
+Lessor and any Beneficiary in connection with the exercise by Lessor or either
+Beneficiary of the rights and remedies provided hereby or at law upon and
+following the occurrence of an Event of Default, including by executing and
+delivering such instruments as Lessor or any Beneficiary shall reasonably
+request. In furtherance of the foregoing, Lessee hereby constitutes and
+appoints Lessor as the true and lawful agent and attorney-in-fact for Lessee
+for purposes of executing and delivering any instrument that may be necessary
+or appropriate in order to carry into effect any right or remedy of Lessor or
+any Beneficiary hereunder upon and following the occurrence of an Event of
+Default, including any consent to the de-registration of the Aircraft from the
+FAA. Any such instrument signed pursuant to the foregoing appointment may be
+signed in Lessee's name or in the name of Lessor. The foregoing appointment is
+coupled with an interest and is irrevocable.
+
+ No remedy referred to in this Section 18 is intended to be
+exclusive, but, to the extent permissible hereunder or under applicable Law,
+each shall be cumulative and in addition to any other remedy referred to above
+or otherwise available to Lessor at Law or in equity; and the exercise or
+beginning of exercise by Lessor of any one or more of such remedies shall not
+preclude the simultaneous or later exercise by Lessor of any or all of such
+other remedies. No express or implied waiver by Lessor of any Default shall in
+any way be, or be construed to be, a waiver of any future or subsequent
+Default.
+
+ Section 19. ALIENATION.
+
+ Lessor and each Beneficiary shall have the right at its sole
+cost and expense to assign, sell, encumber or otherwise dispose of any interest
+of Lessor or such Beneficiary in, to or under the Aircraft, the Trust Agreement
+or this Lease and/or the proceeds hereof, subject to the rights of Lessee under
+the provisions of this Lease,
+
+
+ -73-
+
+
+
+including by sale, transfer, pledge, assignment or other disposition to any
+Lender or to any other Person (other than an air carrier engaged in the airline
+business); PROVIDED, HOWEVER, that unless an Event of Default shall have
+occurred and be continuing, neither Lessor nor any Beneficiary shall undertake
+any action that (i) interferes with Lessee's rights under Section 20(f) hereof,
+(ii) disqualifies the Aircraft for registry with the FAA, or (iii) results in
+an increase in any liability of Lessee under Section 10, unless Lessor and each
+Beneficiary agree to waive their rights to be indemnified for any such increase
+in liability. To effect or facilitate any such sale, transfer, pledge,
+assignment, or other disposition, Lessee agrees to provide, at Lessor's sole
+cost and expense, such agreements, consents, conveyances or documents as may be
+reasonably requested by Lessor or such Beneficiary, which shall include,
+without limitation, a consent to such disposition executed by Lessee and in the
+case of an assignment of the Lease (other than an assignment for security
+purposes) an unrestricted release of Lessor from any obligations under this
+Lease arising after the date of such assignment; PROVIDED, HOWEVER, that such
+release shall not affect any liability of Lessor or such Beneficiary arising on
+or before the date of such assignment. Lessee hereby agrees that it will not
+assert against an assignee any Claim or defense which it may have against
+Lessor or such Beneficiary; PROVIDED, HOWEVER, that any such Claim or defense
+will survive such assignment and continue to be maintained against Lessor or
+such Beneficiary. No assignment or transfer hereunder shall result in Lessee
+being obligated to pay for the account of Lessor or such Beneficiary any
+greater amount than it would otherwise be obligated to pay hereunder, including
+without limitation any obligation of Lessee to pay amounts pursuant to Section
+10. The agreements, covenants, obligations, and liabilities contained herein
+including, but not limited to, all obligations to pay Rent and indemnify each
+Indemnitee are made for the benefit of each Indemnitee and their respective
+successors and assigns. In the event this Lease is assigned, or otherwise
+disposed of by Lessor or either Beneficiary, any assignee, transferee or
+mortgagee shall agree in writing with Lessee as a condition precedent thereto
+to be bound by the provisions of this Lease and not to disturb or otherwise
+interfere with the quiet enjoyment of Lessee of the Aircraft in accordance with
+the terms of this Lease so long as no Event of Default shall have occurred and
+be continuing.
+
+ Lessee shall include each Lender or any Person to whom an
+interest herein is assigned as an additional insured and loss payee in
+accordance with the provisions of Section 12 hereof and indemnify such Lender
+to the same extent Lessee has agreed to indemnify Lessor pursuant to Sections
+10 and 13 hereof. No Lender or any Person to whom an interest herein is
+assigned shall have any liability for the obligations of Lessor under any
+provision of this Lease.

+Section 20. MISCELLANEOUS.
+
+ (a) SEVERABILITY, AMENDMENT AND CONSTRUCTION. Any provision of this
+Lease which is prohibited or unenforceable in any jurisdiction shall, as to
+such jurisdiction, be ineffective to the extent of such prohibition or
+unenforceability without invalidating the remaining provisions hereof; any
+such prohibition or unenforceability in any jurisdiction shall not
+invalidate or render unenforceable such provision in any other jurisdiction.
+To the extent permitted by Law, Lessee hereby waives any provisions of Law
+which renders any provisions hereof prohibited or unenforceable in any
+respect. Lessee may not assign this Lease or its rights hereunder. This
+Lease supersedes any prior or contemporaneous agreements, whether oral or in
+writing, of the parties hereto and shall constitute the entire agreements of
+the parties hereto. No term or provision of this Lease may be changed,
+waived, discharged or terminated orally, but only by an instrument in
+writing expressed to be a supplement or amendment to this Lease signed under
+hand by an officer of the party against which the enforcement of the change,
+waiver, discharge or termination is sought. This Lease shall constitute an
+agreement of lease, and nothing herein shall be construed as conveying to
+Lessee any right, title or interest in the Aircraft or any Engine or Part
+except as a lessee only. The headings in this Lease are for convenience of
+reference only and shall not define or limit any of the terms of provisions
+hereof. Whenever required by the context hereof, the singular shall include
+the plural and vice versa. Reference to this Lease shall mean this Lease as
+amended or supplemented from time to time.
+
+ (b) GOVERNING LAW; JURISDICTION. This Lease shall in all respects be
+governed by, and construed in accordance with, the laws of the State of New
+York, except that the provisions of Section 21(a) (Security Deposit) and
+Section 21(b)(vi) shall be governed by the laws of the State of Delaware.
+
+ A. Lessee and Lessor each hereby irrevocably and expressly submit to
+the non-exclusive jurisdiction of the United States District Court for the
+Southern District of New York and to the New York Supreme Court, New York
+County for the purposes of any suit, action or proceeding arising out of
+this Lease or the Operative Documents. Final judgment against Lessee or
+Lessor in any such suit shall be conclusive, and may be enforced in any
+other jurisdictions by suit on the judgment or as otherwise permitted by
+applicable Law, a certified or true copy of which shall be conclusive
+evidence of the fact and of the amount of any indebtedness or liability of
+such party therein described; PROVIDED, HOWEVER, that Lessor or Lessee may
+at its option bring suit, or institute other judicial proceedings against
+the other party or any of its assets, in the courts of any
+
+ -75-
+
+
+
+
+
+country or place where such party or such assets may be found.
+
+ B. Each of Lessee and Lessor hereby irrevocably waives any objection
+which it may now or hereafter have to the laying of venue of any suit,
+action or proceeding brought in any court located in New York City, New York
+and hereby further irrevocably waives any claim that any such suit, action
+or proceeding brought in any such court has been brought in an inconvenient
+forum.
+
+ C. The foregoing submission to jurisdiction shall not be construed so
+as to limit the right of either party to take proceedings against the other
+in whatsoever jurisdictions shall to it seem fit nor shall the taking of
+proceedings in any one or more jurisdictions preclude the taking of
+proceedings in any other jurisdiction, whether concurrently or not.
+
+ D. Lessee hereby irrevocably appoints CT Corporation System, Inc., 1633
+Broadway, New York, New York 10019, as Lessee's agent and attorney-in-fact
+(the "Agent"), upon whom all service of summonses and other legal processes
+may be made with respect to any action, suit or proceeding relating to this
+Lease or any other Operative Document. The appointment of such Agent shall
+be irrevocable, and if the Agent revokes such relationship, prior to the
+effective date of such revocation, Lessee shall appoint a successor, which
+successor shall be in accordance with the provisions hereof. Prior to such
+change Lessee shall notify Lessor of such change of Agent. Lessee consents
+and agrees that any service under or in connection with this Lease shall be
+duly completed and served if mailed to Lessee at its address specified below
+or to the Agent at the address specified above, in either case, by
+registered or certified mail.
+
+ (c) NOTICES. All notices required under the terms and provisions hereof
+shall be in writing and any such notice shall become effective when
+deposited in the mails, registered with proper postage for air mail prepaid,
+or, if in the form of a telegram, telex or telecopy, when received,
+addressed if to the Lessee, the Lessor or any Beneficiary at their
+respective addresses set forth in Exhibit C-2 (or such other address as may
+be designated by the Lessee, the Lessor or such Beneficiary to the others).
+
+ (d) LESSOR'S RIGHT TO PERFORM FOR LESSEE. if Lessee fails to make any
+payment of Supplemental Rent required to be made by it hereunder or fails to
+perform or comply with any covenant, agreement or obligation contained
+herein, Lessor or any Beneficiary shall have the right but not the obligation
+ to make such payment or conform or comply with such agreement, covenant or
+obligation, and the amount of such payment and the amount of the reasonable
+expenses of Lessor or such Beneficiary incurred in connection with such
+payment or the performance thereof or compliance therewith,
+
+ -76-
+
+
+
+
+
+together with interest thereon at the Overdue Rate, shall be payable by
+Lessee to Lessor or such Beneficiary (as Supplemental Rent) upon demand.
+Lessor agrees to notify Lessee in writing prior to making any payment under
+this Section 20(d) (giving Lessee the opportunity to rectify the omission),
+unless the Aircraft will be in danger of loss, sale, confiscation,
+forfeiture or seizure should such payment not be made. The taking of any
+such action by Lessor or any Beneficiary pursuant to this Subsection 20(d)
+shall not constitute a waiver or release of any obligation of Lessee under
+the Lease, nor a waiver of any Event of Default which may arise out of
+Lessee's nonperformance of such obligation, nor an election or waiver by
+Lessor of any remedy or right available to Lessor under or in relation to
+this Lease.
+
+ (e) COUNTER PARTS. This Lease may be executed simultaneously in two or
+more counterparts, each of which shall be deemed an original, but all of
+which together shall constitute one and the same instrument. To the extent,
+if any, that this Lease constitutes chattel paper (as such term is defined in
+ the Uniform Commercial Code as in effect in any applicable jurisdiction) no
+security interest in this Lease may be created through the transfer or
+possession of any counterpart other than the counterpart which has been
+marked "Counterpart No. 1 - Chattel Paper Original" on the cover page
+thereof.
+
+ (f) QUIET ENJOYMENT. Lessor covenants that so long as an Event of
+Default shall not have occurred and be continuing, Lessee shall be entitled
+to quiet use, possession and enjoyment of the Aircraft in accordance with
+the terms of this Lease, without interference by Lessor or by any Person
+lawfully claiming by or through Lessor.
+
+ (g) BROKERS. Each party agrees to indemnify and hold the other harmless
+from and against any and all claims, suits, damages, costs and expenses
+(including, but not limited to, reasonable attorneys' fees) asserted by any
+agent, broker or other third party for any commission or compensation of any
+nature whatsoever based upon the lease of the Aircraft, if such claim,
+damage, cost or expense arises out of any action or alleged action by the
+indemnifying party, its employees or agents.
+
+ (h) FUNDING INDEMNITY. Without prejudice to any other rights Lessor or
+each Beneficiary may have under the terms of this Lease or any of the
+Operative Documents or otherwise,
+
+ (A) if Lessor or each Beneficiary (and/or any of Beneficiary's
+ Affiliates) enters into any Dollar based bank funding or
+ financing arrangement (including, without limitation, any swap,
+ hedge or similar arrangement, but excluding any currency swap or
+ currency hedge to which Lessee has not
+
+ -77-
+
+
+
+
+
+ consented) in connection with the fixing of the Basic Rent,
+ which is payable during the Term, and if the Aircraft shall not
+ be delivered to Lessee in accordance with the terms of this
+ Lease (other than by reason of the willful default of Lessor),
+ Lessee shall indemnify Lessor or each Beneficiary (and/or any of
+ Beneficiary's Affiliates) against, and shall pay on an after tax
+ basis to Lessor or each Beneficiary (and/or any of Beneficiary's
+ Affiliates) forthwith on demand, subject to the proviso set
+ forth below, all costs, fees (including, without limitation,
+ legal fees) expenses, obligations, liabilities and any other
+ amounts notified by the Beneficiaries to the Lessee (which
+ notification shall set out in reasonable detail the calculation
+ of the amounts claimed therein and such notification shall, in
+ the absence of manifest error, be conclusive) as having been
+ incurred, suffered or expended by Lessor or any Beneficiary
+ (and/or any of Beneficiary's Affiliates) or arising in connection
+ with the amendment, variation, rolling over, termination,
+ reconstitution, hedging, unwinding, covering or other adjustment
+ of any Dollar based bank funding or financing arrangement
+ (including, without limitation, any swap, hedge or similar
+ arrangement, but excluding any currency swap or currency hedge to
+ which Lessee has not consented) entered into or committed by
+ Lessor or any Beneficiary (and/or any of Beneficiary"s Affiliates)
+ for the purposes of the financing of the Aircraft and/or its
+ leasing to Lessee on the basis of the Basic Rent provided for
+ under this Lease; PROVIDED, HOWEVER, that if the interruption of
+ the Beneficiaries' funding results in a gain to the Beneficiaries
+ (net of Taxes or other charges incurred in connection therewith),
+ then, so long as no Default exists, the Beneficiaries shall remit
+ the amount of such gain (net of their costs relating to the
+ negotiation, preparation and execution of this Agreement and the
+ consummation of the transactions contemplated hereby) to Lessee;
+
+ (B) if an Event of Default occurs and the Aircraft is not delivered
+ or is repossessed in accordance with the terms of this Agreement
+ or otherwise, or if the Term is terminated earlier than the
+ Expiration Date by any reason including but not limited to the
+ early termination of the Term referred in clause 2(ii)(B) of the
+ Supplemental Agreement or a Casualty Occurrence (if such Casualty
+ Occurrence is covered by the insurance required by Section 12),
+ then Lessee shall indemnify Lessor or each Beneficiary (and/or
+ Beneficiary's Affiliate) against and shall pay on
+
+ -78-
+
+
+
+
+
+ an after tax basis to Lessor (and/or Beneficiary's Affiliate)
+ forthwith on demand, subject as provided below, all reasonable
+ costs, fees (including, without limitation, legal fees), expenses
+ obligations, liabilities and other amounts notified by the
+ Beneficiaries to Lessee (which notification shall set out the
+ calculation of the amounts claimed therein and such notification
+ shall, in the absence of manifest error, be conclusive) as having
+ been incurred, suffered or expended in connection with the
+ amendment, variation, rolling over, termination, reconstitution,
+ hedging, unwinding, covering or other adjustment of any Dollar
+ based bank funding or financing arrangement (including, without
+ limitation, any swap, hedge or similar arrangement, but excluding
+ any currency swap or currency hedge to which Lessee has not
+ consented) entered into or committed by Lessor or each Beneficiary
+ (and/or any of Beneficiary's Affiliates) for the purposes of the
+ financing of the Aircraft by Lessor or each Beneficiary and/or its
+ leasing of the Aircraft to Lessee on the basis of the fixed Basic
+ Rent provided for under this Lease;
+
+ PROVIDED THAT the provisions of (A) or (B) shall not impose or be
+ deemed to impose on Lessee any obligation for payment of any
+ amount representing the principal amount of any bank funding
+ or financing arrangement.
+
+ (i) PAYMENTS IN U.S. DOLLARS. All amounts to be paid hereunder to
+Lessor or Lessee shall be paid in Dollars, in immediately available funds.
+Lessee acknowledges that the specification of Dollars in this transaction is
+of the essence and that Dollars shall be the currency of account in any and
+all events. The obligations of Lessee or Lessor hereunder, to Lessor or
+Lessee, respectively, shall not be discharged by an amount paid in another
+currency, whether pursuant to a judgment or otherwise, to the extent that the
+ amount so paid on prompt conversion to Dollars under normal banking
+procedures does not yield the amount of Dollars owing to Lessor. In the
+event that any payment by Lessee or Lessor, respectively, whether pursuant
+to judgment or otherwise to Lessor or Lessee, respectively, upon conversion
+does not yield such amount of Dollars, Lessor or Lessee, as the case may be,
+shall have a separate cause of action against Lessee or Lessor, as the case
+may be, for the additional amount necessary to yield the amount of Dollars
+due and owing to Lessor or Lessee, as the case may be.
+
+ (j) COSTS. Each party hereto shall bear its own costs in respect of the
+preparation, negotiation and execution of this Lease, the Lease Supplement
+and any document ancillary thereto; PROVIDED, HOWEVER, that Lessor shall bear
+
+ -79-
+
+
+
+
+
+the costs and expenses incurred in connection with the registration of the
+Aircraft with the FAA (including the legal fees and expenses of special FAA
+counsel) and Lessee shall bear the costs and expenses incurred in connection
+with the filing and registration of the Lease and any change in the FAA
+registration number of the Aircraft requested by Lessee and approved by the
+Beneficiaries (including, without limitation, the legal fees and expenses of
+special FAA counsel).
+
+ (k) CONFIDENTIALITY. Neither Lessor nor Lessee hereto shall, at any
+time during the Term or after its termination or expiration, disclose to any
+Person any information relating to the matters set forth in this Lease or
+the business, financial or other affairs a confidential nature relating to
+the other party which may, in the course of the transactions contemplated
+hereby, have been disclosed or discovered, except that any such information
+may be so disclosed (i) with the written authority of the other party
+hereto, (ii) so far as may be necessary for the proper performance of its
+obligations hereunder, including the filing of this Lease with the FAA,
+(iii) to the extent required by law, ordered by a court of competent
+jurisdiction or by the relevant Governmental Entity responsible for taxation
+or any other applicable regulatory authority, (iv) to such party's auditors,
+counsel or other professional advisers, (v) to any Affiliate of a
+Beneficiary and (vi) to the extent required in connection with a public
+offering of debt or equity securities by Lessee. The parties hereto shall
+use all reasonable endeavors to prevent any such disclosure as aforesaid,
+except that Lessor or any Beneficiary may provide any potential purchaser of
+the Aircraft, any Lender or any potential assignee of this Lease or any of
+the Operative Documents with such information that any such person shall
+reasonably request of Lessor or such Beneficiary.
+
+ (l) SECTION 1110. The parties agree that Lessor and the Beneficiaries
+are entitled to the benefits and protections of Section 1110 of the U.S.
+Bankruptcy Code ("Section 1110"), and Lessee shall take such actions and
+effect such filings as may be necessary to enable Lessor and the
+Beneficiaries to continue to be entitled to such benefits and protections at
+all times from the date of the execution and delivery hereof until such time
+as the Aircraft is returned to Lessor or the Beneficiaries in compliance
+with the return conditions herein and this Lease is terminated. Lessee
+acknowledges that this Section is of fundamental importance to the
+transactions contemplated hereby and that neither Lessor nor the
+Beneficiaries would have entered into this Lease but for the rights intended
+to be conveyed to Lessor and the Beneficiaries by this Section and the
+protection and benefits of Section 1110.
+
+ (m) CONCERNING THE LESSOR. Wilmington Trust Company is entering into
+this Lease solely in its capacity
+
+ -80-
+
+
+
+
+
+as Trustee under the Trust Agreement and not in its individual capacity. As
+such, Wilmington Trust Company shall not be liable for or on account of any
+statements, representations, warranties, covenants or obligations stated to
+be those of Lessor hereunder.
+
+ (n) TRUE LEASE. THIS LEASE SHALL CONSTITUTE AN AGREEMENT OF LEASE AND
+IS A TRUE OPERATING LEASE, AND NOTHING HEREIN SHALL BE CONSTRUED AS
+CONVEYING TO LESSEE ANY RIGHT, TITLE, OR INTEREST IN THE AIRCRAFT OR ANY
+ENGINE OR PART EXCEPT AS A LESSEE ONLY. WITHOUT LIMITING THE FOREGOING,
+LESSEE WILL NOT FILE A TAX RETURN OR TAKE ANY OTHER ACTION WHICH IS
+INCONSISTENT WITH THE FOREGOING.
+
+ Section 21. SECURITY DEPOSIT.
+
+ (a) SECURITY DEPOSIT. Lessor hereby acknowledges Beneficiaries' receipt
+from Lessee of the Security Deposit subject to the Security Deposit
+Adjustment. In the event that the transactions contemplated by this Lease
+are not consummated (other than due to the fault of Lessee or the occurrence
+of an Event of Default), Lessor shall cause the Beneficiary to refund the
+Security Deposit (so long as no Default or Event of Default has occurred,
+without deducting any costs incurred by any Beneficiary or Lessor in
+connection with the proposed leasing of the Aircraft hereunder but after
+deducting the break funding costs incurred by the Beneficiaries and specified
+ in Section 20(h), if any) to Lessee. The Security Deposit is received by
+Lessor or the Beneficiaries as security for the timely and faithful
+performance by Lessee of all of Lessee's obligations under this Lease, and
+Lessee hereby grants Lessor a security interest therein and in all other
+sums deposited under this Section 21(a). Lessee agrees to execute and file
+with the appropriate Governmental Entities any and all documents necessary
+or reasonably requested by Lessor or any Beneficiary to evidence and perfect
+such security assignment in favor of Lessor. If Lessee fails to pay Rent
+hereunder when due or to pay any other sums due or to perform any of the
+other terms and provisions of this Lease or is otherwise in Default
+hereunder, in addition to all other rights Lessor shall have under the New
+York Uniform Commercial Code as a secured party, Lessor may use, apply or
+retain all or any portion of the Security Deposit in partial payment for
+sums due to Lessor by Lessee, to compensate Lessor for any sums it may in

+losses or expenses Lessor may suffer or incur as a result of Lessee's
+Default hereunder. If Lessor uses or applies all or any portion of such
+Security Deposit, such application shall not be deemed a cure of any
+Defaults, and Lessee shall within five (5) days after written demand
+therefor deposit with Lessor in cash an amount sufficient to restore the
+Security Deposit to the aggregate amount of such Security Deposit prior to
+Lessor's use or application and the failure of Lessee to do so shall be a
+material breach of
+
+ -81-
+
+
+
+
+
+this Lease by Lessee. Provided Lessee is not in Default under this Lease,
+such Security Deposit, less any costs incurred by Lessor in connection with
+the termination of the Lease or return of the Aircraft, shall be returned to
+Lessee promptly after the Expiration Date and Lessee's return of the
+Aircraft in compliance with Section 16 hereof. Lessee shall not be entitled
+to any interest earned on the Security Deposit.
+
+ (b) SECURITY LETTER OF CREDIT.
+
+ (i) Lessee hereby agrees with Lessor that, subject to paragraph
+ (vi) below, Lessee shall deliver to Lessor (or if specified by
+ the Beneficiaries, the Beneficiaries) the duly executed Security
+ Letter of Credit for the amount specified in Exhibit C-1.
+
+ (ii) The Security Letter of Credit shall remain in full force and
+ effect from the date hereof until the date that is three months
+ after the Expiration Date, provided that it may be renewable
+ annually so long as Lessor or the Beneficiaries may draw upon the
+ Security Letter of Credit at any time if the Security Letter of
+ Credit is not renewed on or before thirty (30) days prior to its
+ stated expiration or if Lessor or a Beneficiary receives a
+ termination notice from the issuing bank or institution.
+
+ (iii) Lessor or the Beneficiaries may draw upon the Security Letter of
+ Credit upon the occurrence and during the continuation of an
+ Event of Default and apply the proceeds thereof in or towards the
+ satisfaction of any sum or obligation due to Lessor or any
+ Beneficiary by Lessee which either Lessee fails to pay on the
+ due date or, as the case may be, the date of demand or after any
+ applicable grace period permitted for the payment thereof and/or
+ under this Lease or any of the Operative Documents or to
+ compensate Lessor or any Beneficiary for any sum which it may in
+ its discretion advance or expend as a result of the failure of
+ Lessee to comply with any of its obligations under this Lease or
+ any of the Operative Documents or in respect of any Default or
+ Event of Default, in respect of any indemnity payments, in any
+ case by delivering to the issuing bank or institutions a notice
+ in accordance with the terms of the Security Letter of Credit.
+ No such drawing under the Security Letter of Credit shall operate
+ to relieve Lessee of any obligation hereunder or constitute the
+ satisfaction of any such obligation (except to the extent of the
+ proceeds of such payment actually received by Lessor and the
+ Beneficiaries).
+
+ -82-
+
+
+
+
+
+ (iv) Upon any such drawing by Lessor or a Beneficiary, Lessee shall
+ reimburse the issuing bank and or a Beneficiary otherwise take
+ such action as may be necessary in order to restore the amount
+ available for drawing under the Security Letter of Credit to the
+ amount of such Security Letter of Credit specified in Exhibit C-1
+ promptly (and in any event within five Business Days) after such
+ Lessor's drawing and shall procure promptly that the issuing bank
+ or institutions forward a further letter of credit or guarantee
+ to Lessor evidencing that the amount has so been restored.
+
+ (v) Provided that no Default, or Event of Default has occurred and is
+ continuing, Lessor shall return the Security Letter of Credit to
+ Lessee for cancellation promptly after the date upon which the
+ Aircraft is redelivered to Lessor in accordance with the terms of
+ this Lease.
+
+ (vi) Notwithstanding the foregoing provisions of this Section 21(b),
+ Lessee may, on the Delivery Date, in lieu of the delivery to the
+ Beneficiaries of the Security Letter of Credit on the Delivery
+ Date, deposit with the Beneficiaries an amount in cash equal to
+ the amount of the Security Letter of Credit, as specified in
+ Exhibit C-1 (the "Security Letter of Credit Amount"). If Lessee
+ elects to make such deposit in lieu of the delivery of the
+ Security Letter of Credit, then Lessee shall effect such deposit
+ by wire transfer of funds to an account specified by one of the
+ Beneficiaries, and such Security Letter of Credit Amount shall
+ constitute part of the Security Deposit and shall be held by the
+ Beneficiaries as collateral security for the payment and
+ performance by the Lessee of its obligations hereunder and under
+ the other Operative Documents. The Beneficiaries shall have the
+ same rights, and shall be permitted to apply such Security Letter
+ of Credit Amount in the same manner, as is set forth in
+ Sections 18(i) and 21(a) above with respect to the Security
+ Deposit. Following the Delivery Date, Lessee shall have the
+ option of substituting the Security Letter of Credit described
+ above in this Section 21(b) in exchange for the Security Letter
+ of Credit Amount deposited with the Beneficiaries pursuant to
+ this clause (vi). To effect such substitution, Lessee shall
+ deliver the originally issued and executed Security Letter of
+ Credit (in the form and scope and in the amount required by
+ Exhibit C-1) to Lessor, and, promptly after Lessor's receipt
+ thereof, the Beneficiaries shall, so long as no Default or Event
+ of Default shall have occurred and be continuing, return the
+ Security Letter of
+
+ -83-
+
+
+
+
+
+ Credit Amount paid on the Delivery Date pursuant to this
+ clause (iv) to Lessee. If Lessee does not substitute the Security
+ Letter of Credit Amount with the Security Letter of Credit, so
+ long as no Default or Event of Default shall have occurred and be
+ continuing, the Security Letter of Credit Amount will be returned
+ to Lessee promptly after the return of the Aircraft pursuant to
+ Section 21(a).

+ 4,000 Flight Hours remaining until the next due D check or
+ its equivalent in accordance with the Subsequent User's
+ maintenance program.
+
+ (iii) In addition to (i) above, if the Beneficiaries request that

+ equivalent, Lessee will perform, or procure the performance
+ of, such D Check or equivalent, with Lessor contributing to
+ the cost of such D Check or equivalent by paying to Lessee
+ the incrementary cost (without markup) to perform such D
+ Check or equivalent; provided that the Term will not be
+ deemed to be extended solely because of such D Check or
+ equivalent.

+ (b) The condition of the Aircraft and installed systems upon return to
+ Lessor shall be as follows:
+
+
+
+
+
+ (i) each Engine and each life limited Part therein shall have no

+ remaining to the next scheduled replacement.
+
+ (ii) the APU and each life limited Part therein (if applicable)
+ shall have no less hours or time (whichever is applicable and
+ the more limiting factor) remaining until the next due
+ scheduled removal and overhaul as on the Delivery Date, and
+ Lessee shall have the option to swap APUs to meet the
+ requirements of this paragraph (ii);

+ (iii) the Landing Gear of the Aircraft and other time or life limited
+ parts of the Landing Gear shall have no less Flight Hours or
+ Cycles or any other life limit (whichever is applicable and
+ the more limiting factor) remaining until the next due
+ scheduled removal and overhaul as on the Delivery Date, and
+ Lessee shall have the option to swap Landing Gear to meet the
+ requirements of this paragraph (iii).
+
+3 OTHER MATTERS
+
+ (a) Provided necessary material and instructions are received in due
+ time (other than materials available by Lessee), any further work
+ required by the Beneficiaries, which can be accommodated within
+ the days already planned by Lessee for the above inspection and
+ check as set forth in paragraph 2(a) above, shall be performed, or
+ performance thereof shall be procured, by Lessee during the above
+ check and Lessor shall reimburse Lessee for the incremental costs

+subject, as to enforceability, to applicable bankruptcy, insolvency,
+reorganization, moratorium or other similar laws affecting the enforcement of
+creditors' rights generally, and, to general principles of equity.
+
+ 5. To our knowledge, there are no pending suits or proceedings
+before any court or any regulatory commission, board or other administrative
+governmental agency against or affecting Lessee which might have a materially

+
+ ## About
+
+ This extension takes a dataset as input, breaks it into chunks, and adds the result to a local/offline Chroma database.
+
+ The database is then queried during inference time to get the excerpts that are closest to your input. The idea is to create an arbitrarily large pseudo context.
+
+ The core methodology was developed and contributed by kaiokendev, who is working on improvements to the method in this repository: https://github.com/kaiokendev/superbig
+
+ ## Data input
+
+ Start by entering some data in the interface below and then clicking on "Load data".
+
+ Each time you load some new data, the old chunks are discarded.
+
+ ## Chat mode
+
+ #### Instruct
+
+ On each turn, the chunks will be compared to your current input and the most relevant matches will be appended to the input in the following format:
+
+ ```
+ Consider the excerpts below as additional context:
+ ...
+ ```
+
+ The injection doesn't make it into the chat history. It is only used in the current generation.
+
+ #### Regular chat
+
+ The chunks from the external data sources are ignored, and the chroma database is built based on the chat history instead. The most relevant past exchanges relative to the present input are added to the context string. This way, the extension acts as a long term memory.
+
+ ## Notebook/default modes
+
+ Your question must be manually specified between `<|begin-user-input|>` and `<|end-user-input|>` tags, and the injection point must be specified with `<|injection-point|>`.
+
+ The special tokens mentioned above (`<|begin-user-input|>`, `<|end-user-input|>`, and `<|injection-point|>`) are removed in the background before the text generation begins.
+
+ Here is an example in Vicuna 1.1 format:
+
+ ```
+ A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
+
+ USER:
+ <|injection-point|>
+
+ <|begin-user-input|>What datasets are mentioned in the text above?<|end-user-input|>
+ ASSISTANT:
+ ```
